Merge drm/drm-next into drm-misc-next
We haven't done any backmerge for a while due to the merge window, and it
starts to become an issue for komeda. Let's bring 5.4-rc1 in.

6b5ce4a1fb drm/vram: Move VRAM memory manager to GEM VRAM implementation
The separation between GEM VRAM objects and the memory manager is
artificial, as they are only used with each other. Copying both
implementations into the same file is a first step to simplifying
the code.

This patch only moves code without functional changes.

v3:
	* update to use dev->vma_offset_manager
v2:
	* update for debugfs support
	* typos in commit message

ff540b76f1 drm/ttm: add drm gem ttm helpers, starting with drm_gem_ttm_print_info()
Now with ttm_buffer_object being a subclass of drm_gem_object we can
easily lookup ttm_buffer_object for a given drm_gem_object, which in
turn allows to create common helper functions.

This patch starts off with a drm_gem_ttm_print_info() helper function
which adds some ttm specific lines to the debug output.

8e7cb1799b drm/i915: Extract intel_frontbuffer active tracking
Move the active tracking for the frontbuffer operations out of the
i915_gem_object and into its own first class (refcounted) object. In the
process of detangling, we switch from low level request tracking to the
easier i915_active -- with the plan that this avoids any potential
atomic callbacks as the frontbuffer tracking wishes to sleep as it
flushes.

tinydrm_display_pipe_init() has only one user now, so move it to mipi-dbi.

Changes:
- Remove drm_connector_helper_funcs.detect, it's always connected.
- Store the connector and mode in mipi_dbi instead of it's own struct.

Otherwise remove some leftover tinydrm-helpers.h inclusions.

d23d4d4dac drm/tinydrm: Move tinydrm_spi_transfer()
This is only used by mipi-dbi drivers so move it there.

The reason this isn't moved to the SPI subsystem is that it will in a
later patch pass a dummy rx buffer for SPI controllers that need this.
Low memory boards (64MB) can run into a problem allocating such a "large"
contiguous buffer on every transfer after a long up time.
This leaves a very specific use case, so we'll keep the function here.
mipi-dbi will first go through a refactoring though, before this will
be done.

Remove SPI todo entry now that we're done with the tinydrm.ko SPI code.

v2: Drop moving the mipi_dbi_spi_init() declaration (Sam)

0ccf52badd drm/vram: Don't export driver callback functions for PRIME
PRIME functionality is now provided by GEM object functions. The driver
callback functions are obsolete. So this patch renames them and turns
them into static internal functions of the VRAM helper library. The
implementation of gem_prime_mmap is now unused and the patch removes it.

v3:
	* kept each renamed function at its original location within file
	* kept documentation

805dc614d5 drm/prime: Update docs
Yes this is a bit a big patch, but since it's essentially a complete
rewrite of all the prime docs I didn't see how to better split it up.

Changes:
- Consistently point to drm_gem_object_funcs as the preferred hooks,
  where applicable.

- Document all the hooks in &drm_driver that lacked kerneldoc.

- Completely new overview section, which now also includes the cleaned
  up lifetime/reference counting subchapter. I also mentioned the weak
  references in there due to the lookup caches.

- Completely rewritten helper intro section, highlight the
  import/export related functionality.

- Polish for all the functions and more cross references.

I also sprinkled a bunch of todos all over.

Most important: 0 code changes in here. The cleanup motivated by
reading and improving all this will follow later on.

v2: Actually update the prime helper docs. Plus add a few FIXMEs that
I won't address right away in subsequent cleanup patches.

v3:
- Split out the function moving. This patch is now exclusively
  documentation changes.
- Typos and nits (Sam).

v4: Polish suggestions from Noralf.

1452c25b0e drm: Add helpers to kick off self refresh mode in drivers
This patch adds a new drm helper library to help drivers implement
self refresh. Drivers choosing to use it will register crtcs and
will receive callbacks when it's time to enter or exit self refresh
mode.

In its current form, it has a timer which will trigger after a
driver-specified amount of inactivity. When the timer triggers, the
helpers will submit a new atomic commit to shut the refreshing pipe
off. On the next atomic commit, the drm core will revert the self
refresh state and bring everything back up to be actively driven.

From the driver's perspective, this works like a regular disable/enable
cycle. The driver need only check the 'self_refresh_active' state in
crtc_state. It should initiate self refresh mode on the panel and enter
an off or low-power state.

Changes in v2:
- s/psr/self_refresh/ (Daniel)
- integrated the psr exit into the commit that wakes it up (Jose/Daniel)
- made the psr state per-crtc (Jose/Daniel)
Changes in v3:
- Remove the self_refresh_(active|changed) from connector state (Daniel)
- Simplify loop in drm_self_refresh_helper_alter_state (Daniel)
- Improve self_refresh_aware comment (Daniel)
- s/self_refresh_state/self_refresh_data/ (Daniel)
Changes in v4:
- Move docbook location below panel (Daniel)
- Improve docbook with references and more detailed explanation (Daniel)
- Instead of register/unregister, use init/cleanup (Daniel)
Changes in v5:
- Resolved conflict in drm_atomic_helper.c #include block
- Resolved conflict in rst with HDCP helper docs
Changes in v6:
- Fix include ordering, clean up forward declarations (Sam)

e5852bee90 drm/fb-helper: Remove drm_fb_helper_connector
All drivers add all their connectors so there's no need to keep around an
array of available connectors. Instead we just put the useable (not
writeback) connectors in a temporary array using
drm_client_for_each_connector_iter() everytime we probe the outputs.
Other places where it's necessary to look at the connectors, we just
iterate over them using the same iterator function.

Rename functions which signature is changed since they will be moved to
drm_client in a later patch.

d81294afee drm/fb-helper: Remove drm_fb_helper_crtc
struct drm_fb_helper_crtc is now just a wrapper around drm_mode_set so
use that directly instead and attach it as a modeset array onto
drm_client_dev. drm_fb_helper will use this array to store its modesets
which means it will always initialize a drm_client, but it will not
register the client (callbacks) unless it's the generic fbdev emulation.

Code will later be moved to drm_client, so add code there in a new file
drm_client_modeset.c with MIT license to match drm_fb_helper.c.

The modeset connector array size is hardcoded for the cloned case to avoid
having to pass in a value from the driver. A value of 8 is chosen to err
on the safe side. This means that the max connector argument for
drm_fb_helper_init() and drm_fb_helper_fbdev_setup() isn't used anymore,
a todo entry for this is added.

In pan_display_atomic() restore_fbdev_mode_force() is used instead of
restore_fbdev_mode_atomic() because that one will later become internal
to drm_client_modeset.

Locking order:
1. drm_fb_helper->lock
2. drm_master_internal_acquire
3. drm_client_dev->modeset_mutex

v6: Improve commit message (Sam Ravnborg)

v3:
- Use full drm_client_init/release for the modesets (Daniel Vetter)
- drm_client_for_each_modeset: use lockdep_assert_held (Daniel Vetter)
- Hook up to Documentation/gpu/drm-client.rst (Daniel Vetter)

Date:   Wed Apr 24 11:56:17 2019 -0700

    drm/doc: Document expectation that userspace review looks at kernel uAPI.

there's been concerns raised that we expect userspace people to do
in-depth kernel patch review. That's not reasonable, same way kernel
people can't review all the userspace we have. Try to clarify
expectations a bit more.

5fc537bfd0 drm/mcde: Add new driver for ST-Ericsson MCDE
This adds a new DRM driver for the ST-Ericsson Multi Channel
Display Engine, MCDE display controller.

This hardware has three independent DSI hosts and can composit
and display several memory buffers onto an LCD display. It
was developed for several years inside of ST-Ericsson and
shipped with a few million mobile phones from Sony and Samsung,
as well as with the Snowball community development board.

The driver is currently pretty rudimentary but supports a
simple framebuffer so we can get penguins and graphics when
using these SoCs.

59f5989ad4 drm: Integrate VRAM MM into struct drm_device
There's now a pointer to struct drm_vram_mm stored in struct drm_device.
DRM drivers that use VRAM MM should use this field to refer to their
instance of the data structure. Appropriate helpers are now provided as
well.

Adding struct drm_vram_mm to struct drm_device further avoids wrappers
and boilerplate code in drivers. This patch implements default functions
for callbacks in struct drm_driver and struct file_operations that use
the struct drm_vram_mm stored in struct drm_device. Drivers that need to
provide their own implementations can still do so.

The patch also adds documentation for the VRAM helper library in general.

The VRAM MM memory manager is a helper library that manages dedicated video
memory of simple framebuffer devices. It is supported to be used with
struct drm_gem_vram_object, but does not depend on it.

The implementation is based on the respective code from ast, bochs, and

03a9606e7f drm/fb-helper: Avoid race with DRM userspace
drm_fb_helper_is_bound() is used to check if DRM userspace is in control.
This is done by looking at the fb on the primary plane. By the time
fb-helper gets around to committing, it's possible that the facts have
changed.

Avoid this race by holding the drm_device->master_mutex lock while
committing. When DRM userspace does its first open, it will now wait
until fb-helper is done. The helper will stay away if there's a master.

Two igt tests fail with the new 'bail out if master' rule. Work around
this by relaxing this rule for drm_fb_helper_restore_fbdev_mode_unlocked()
until the tests have been fixed. Add todo entry for this.

Locking rule: Always take the fb-helper lock first.

v5: drm_fb_helper_restore_fbdev_mode_unlocked(): Use
    restore_fbdev_mode_force()

v2:
- Remove drm_fb_helper_is_bound() (Daniel Vetter)
- No need to check fb_helper->dev->master in
  drm_fb_helper_single_fb_probe(), restore_fbdev_mode() has the check.

drm: Add reservation_object to drm_gem_object
Many users of drm_gem_object embed a struct reservation_object into
their subclassed struct, so let's add one to struct drm_gem_object.
This will allow removing the reservation object from the subclasses
and removing the ->gem_prime_res_obj callback.

With the addition, add a drm_gem_reservation_object_wait() helper
function for drivers to use in wait ioctls.

badfa5be85 drm/doc: Make igts for cross-driver stuff strongly suggested
Compared to the RFC[1] no changes to the patch itself, but igt moved
forward a lot:

- gitlab CI builds with: reduced configs/libraries, arm cross build
  and a sysroot build (should address all the build/cross platform
  concerns raised in the RFC discussions).

- tests reorganized into subdirectories so that the i915-gem tests
  don't clog the main/shared tests directory anymore

- quite a few more non-intel people contributing/reviewing/committing
  igt tests patches.

I think this addresses all the concerns raised in the RFC discussions,
and assuming there's enough Acks and no new issues that pop up, we can
go ahead with this.

v2:
- Use "should" (in the usual RFC sense) to make it clear that in the
  end this is all up to reviewer's discretion, as usual (Jani).
- Also in the title s/mandatory/strongly suggested/ (me)
- Make it clear we're not going to block features if a testcase is not
  feasible, given hw and state of igt, both having some good gaps in
  what can be tested (Harry, Eric, Sean, ...).

ebcc0e6b50 drm/dp_mst: Introduce new refcounting scheme for mstbs and ports
The current way of handling refcounting in the DP MST helpers is really
confusing and probably just plain wrong because it's been hacked up many
times over the years without anyone actually going over the code and
seeing if things could be simplified.

To the best of my understanding, the current scheme works like this:
drm_dp_mst_port and drm_dp_mst_branch both have a single refcount. When
this refcount hits 0 for either of the two, they're removed from the
topology state, but not immediately freed. Both ports and branch devices
will reinitialize their kref once it's hit 0 before actually destroying
themselves. The intended purpose behind this is so that we can avoid
problems like not being able to free a remote payload that might still
be active, due to us having removed all of the port/branch device
structures in memory, as per:

commit 91a25e4631 ("drm/dp/mst: deallocate payload on port destruction")

Which may have worked, but then it caused use-after-free errors. Being
new to MST at the time, I tried fixing it;

commit 263efde31f ("drm/dp/mst: Get validated port ref in drm_dp_update_payload_part1()")

But, that was broken: both drm_dp_mst_port and drm_dp_mst_branch structs
are validated in almost every DP MST helper function. Simply put, this
means we go through the topology and try to see if the given
drm_dp_mst_branch or drm_dp_mst_port is still attached to something
before trying to use it in order to avoid dereferencing freed memory
(something that has happened a LOT in the past with this library).
Because of this it doesn't actually matter whether or not we keep keep
the ports and branches around in memory as that's not enough, because
any function that validates the branches and ports passed to it will
still reject them anyway since they're no longer in the topology
structure. So, use-after-free errors were fixed but payload deallocation
was completely broken.

Two years later, AMD informed me about this issue and I attempted to
come up with a temporary fix, pending a long-overdue cleanup of this
library:

commit c54c7374ff ("drm/dp_mst: Skip validating ports during destruction, just ref")

But then that introduced use-after-free errors, so I quickly reverted
it:

commit 9765635b30 ("Revert "drm/dp_mst: Skip validating ports during destruction, just ref"")

And in the process, learned that there is just no simple fix for this:
the design is just broken. Unfortunately, the usage of these helpers are
quite broken as well. Some drivers like i915 have been smart enough to
avoid accessing any kind of information from MST port structures, but
others like nouveau have assumed, understandably so, that
drm_dp_mst_port structures are normal and can just be accessed at any
time without worrying about use-after-free errors.

After a lot of discussion, me and Daniel Vetter came up with a better
idea to replace all of this.

To summarize, since this is documented far more indepth in the
documentation this patch introduces, we make it so that drm_dp_mst_port
and drm_dp_mst_branch structures have two different classes of
refcounts: topology_kref, and malloc_kref. topology_kref corresponds to
the lifetime of the given drm_dp_mst_port or drm_dp_mst_branch in it's
given topology. Once it hits zero, any associated connectors are removed
and the branch or port can no longer be validated. malloc_kref
corresponds to the lifetime of the memory allocation for the actual
structure, and will always be non-zero so long as the topology_kref is
non-zero. This gives us a way to allow callers to hold onto port and
branch device structures past their topology lifetime, and dramatically
simplifies the lifetimes of both structures. This also finally fixes the
port deallocation problem, properly.

Additionally: since this now means that we can keep ports and branch
devices allocated in memory for however long we need, we no longer need
a significant amount of the port validation that we currently do.

Additionally, there is one last scenario that this fixes, which couldn't
have been fixed properly beforehand:

- CPU1 unrefs port from topology (refcount 1->0)
- CPU2 refs port in topology(refcount 0->1)

Since we now can guarantee memory safety for ports and branches
as-needed, we also can make our main reference counting functions fix
this problem by using kref_get_unless_zero() internally so that topology
refcounts can only ever reach 0 once.

be5cadc7e7 drm/todo: Better defio support in the generic fbdev emulation
The current one essentially means you need CMA or a vmalloc backed
object, which makes fbdev emulation a special case.

Since implementing this will be quite a bit of work, capture the idea
in a TODO.

d3b2176782 drm: Add a new plane property to send damage during plane update
FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions
on the plane in framebuffer coordinates of the framebuffer attached to
the plane.

The layout of blob data is simply an array of "struct drm_mode_rect".
Unlike plane src coordinates, damage clips are not in 16.16 fixed point.
As plane src in framebuffer cannot be negative so are damage clips. In
damage clip, x1/y1 are inclusive and x2/y2 are exclusive.

This patch also exports the kernel internal drm_rect to userspace as
drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient
to represent damage for current plane size.

Driver which are interested in enabling FB_DAMAGE_CLIPS property for a
plane should enable this property using drm_plane_enable_damage_clips.

v2:
- Input validation on damage clips against framebuffer size.
- Doc update, other minor changes.

b39b5394fa drm/gem: Add drm_gem_object_funcs
This adds an optional function table on GEM objects.
The main benefit is for drivers that support more than one type of
memory (shmem,vram,cma) for their buffers depending on the hardware it
runs on. With the callbacks attached to the GEM object itself, it is
easier to have core helpers for the the various buffer types. The driver
only has to make the decision about buffer type on GEM object creation
and all other callbacks can be handled by the chosen helper.

drm_driver->gem_prime_res_obj has not been added since there's a todo to
put a reservation_object into drm_gem_object.

v3: Add todo entry

v2: Drop drm_gem_object_funcs->prime_mmap in favour of
drm_gem_prime_mmap() (Daniel Vetter)

v1:
- drm_gem_object_funcs.map -> .prime_map let it only do PRIME mmap like
  the function it superseeds (Daniel Vetter)
- Flip around the if ladders and make obj->funcs the first choice
  highlighting the fact that this the new default way of doing it

[Why]
Documentation is helpful for the community to understand our code.
This change does some high-level documentation of some DM interfaces
with DRM, and the amdgpu base driver.

[How]
An entry for AMDgpu DC has been added to Documentation/gpu/drivers.rst
TOC. amdgpu-dc.rst is created to pull in inline doc-strings, which:
- Provides an overview for "What is DM?"
- Documents AMDgpu DM lifecyle
- Documents IRQ management
- Documents atomic_check and commit_tail interfaces

HLSQ, SP and TP registers are only accessible from a special
aperture and to make matters worse the aperture is blocked from
the CPU on targets that can support secure rendering. Luckily the
GPU hardware has its own purpose built register dumper that can
access the registers from the aperture. Add a5xx specific code
to program the crashdumper and retrieve the wayward registers
and dump them for the crash state.

Also, remove a block of registers the regular CPU accessible
list that aren't useful for debug which helps reduce the size

c76f0f7cb5 drm: Begin an API for in-kernel clients
This the beginning of an API for in-kernel clients.
First out is a way to get a framebuffer backed by a dumb buffer.

Only GEM drivers are supported.
The original idea of using an exported dma-buf was dropped because it
also creates an anonomous file descriptor which doesn't work when the
buffer is created from a kernel thread. The easy way out is to use
drm_driver.gem_prime_vmap to get the virtual address, which requires a
GEM object. This excludes the vmwgfx driver which is the only non-GEM
driver apart from the legacy ones. A solution for vmwgfx will have to be
worked out later if it wants to support the client API which it probably
will when we have a bootsplash client.

935774cd71 drm: Add writeback connector type
Writeback connectors represent writeback engines which can write the
CRTC output to a memory framebuffer. Add a writeback connector type and
related support functions.

Drivers should initialize a writeback connector with
drm_writeback_connector_init() which takes care of setting up all the
writeback-specific details on top of the normal functionality of
drm_connector_init().

Writeback connectors have a WRITEBACK_FB_ID property, used to set the
output framebuffer, and a WRITEBACK_PIXEL_FORMATS blob used to expose the
supported writeback formats to userspace.

When a framebuffer is attached to a writeback connector with the
WRITEBACK_FB_ID property, it is used only once (for the commit in which
it was included), and userspace can never read back the value of
WRITEBACK_FB_ID. WRITEBACK_FB_ID can only be set if the connector is
attached to a CRTC.

Changes since v1:
 - Added drm_writeback.c + documentation
 - Added helper to initialize writeback connector in one go
 - Added core checks
 - Squashed into a single commit
 - Dropped the client cap
 - Writeback framebuffers are no longer persistent

Changes since v2:
 Daniel Vetter:
 - Subclass drm_connector to drm_writeback_connector
 - Relax check to allow CRTC to be set without an FB
 - Add some writeback_ prefixes
 - Drop PIXEL_FORMATS_SIZE property, as it was unnecessary
 Gustavo Padovan:
 - Add drm_writeback_job to handle writeback signalling centrally

Changes since v3:
 - Rebased
 - Rename PIXEL_FORMATS -> WRITEBACK_PIXEL_FORMATS

Chances since v4:
 - Embed a drm_encoder inside the drm_writeback_connector to
   reduce the amount of boilerplate code required from the drivers
   that are using it.

Changes since v5:
 - Added Rob Clark's atomic_commit() vfunc to connector helper
   funcs, so that writeback jobs are committed from atomic helpers
 - Updated create_writeback_properties() signature to return an
   error code rather than a boolean false for failure.
 - Free writeback job with the connector state rather than when
   doing the cleanup_work()

Changes since v7:
 - fix extraneous use of out_fence that is only introduced in a
   subsequent patch.

Changes since v8:
 - whitespace changes pull from subsequent patch

Changes since v9:
 - Revert the v6 changes that free the writeback job in the connector
   state cleanup and return to doing it in the cleanup_work() function

50525c332b drm: content-type property for HDMI connector
Added content_type property to drm_connector_state
in order to properly handle external HDMI TV content-type setting.

v2:
 * Moved helper function which attaches content type property
   to the drm core, as was suggested.
   Removed redundant connector state initialization.

v3:
 * Removed caps in drm_content_type_enum_list.
   After some discussion it turned out that HDMI Spec 1.4
   was wrongly assuming that IT Content(itc) bit doesn't affect
   Content type states, however itc bit needs to be manupulated
   as well. In order to not expose additional property for itc,
   for sake of simplicity it was decided to bind those together
   in same "content type" property.

v4:
 * Added it_content checking in intel_digital_connector_atomic_check.
   Fixed documentation for new content type enum.

v5:
 * Moved patch revision's description to commit messages.

v6:
 * Minor naming fix for the content type enumeration string.

v7:
 * Fix parameter name for documentation and parameter alignment
   in order not to get warning. Added Content Type description to
   new HDMI connector properties section.

v8:
 * Thrown away unneeded numbers from HDMI content-type property
   description. Switch to strings desription instead of plain
   definitions.

v9:
 * Moved away hdmi specific content-type enum from
   drm_connector_state. Content type property should probably not
   be bound to any specific connector interface in
   drm_connector_state.
   Same probably should be done to hdmi_picture_aspect_ration enum
   which is also contained in drm_connector_state. Added special
   helper function to get derive hdmi specific relevant infoframe
   fields.

v10:
 * Added usage description to HDMI properties kernel doc.

v11:
 * Created centralized function for filling HDMI AVI infoframe, based
   on correspondent DRM property value.

57692c94dc drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+
This driver will be used to support Mesa on the Broadcom 7268 and 7278
platforms.

V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's
complicated CL/shader validation scheme.  This massively changes the
GEM behavior, so I've forked off to a new driver.

v2: Mark SUBMIT_CL as needing DRM_AUTH.  coccinelle fixes from kbuild
    test robot. Drop personal git link from MAINTAINERS.  Don't
    double-map dma-buf imported BOs.  Add kerneldoc about needing MMU
    eviction.  Drop prime vmap/unmap stubs.  Delay mmap offset setup
    to mmap time.  Use drm_dev_init instead of _alloc.  Use
    ktime_get() for wait_bo timeouts.  Drop drm_can_sleep() usage,
    since we don't modeset.  Switch page tables back to WC (debug
    change to coherent had slipped in).  Switch
    drm_gem_object_unreference_unlocked() to
    drm_gem_object_put_unlocked().  Simplify overflow mem handling by
    not sharing overflow mem between jobs.
v3: no changes
v4: align submit_cl to 64 bits (review by airlied), check zero flags in
    other ioctls.

4394e96423 drm/xen-front: Remove CMA support
It turns out this was only needed to paper over a bug in the CMA
helpers, which was addressed in

commit 998fb1a0f4
Author: Liviu Dudau <Liviu.Dudau@arm.com>
Date:   Fri Nov 10 13:33:10 2017 +0000

    drm: gem_cma_helper.c: Allow importing of contiguous scatterlists with nents > 1

Without this the following pipeline didn't work:

domU:
1. xen-front allocates a non-contig buffer
2. creates grants out of it

dom0:
3. converts the grants into a dma-buf. Since they're non-contig, the
scatter-list is huge.
4. imports it into rcar-du, which requires dma-contig memory for
scanout.

-> On this given platform there's an IOMMU, so in theory this should
work. But in practice this failed, because of the huge number of sg
entries, even though the IOMMU driver mapped it all into a dma-contig
range.

With a guest-contig buffer allocated in step 1, this problem doesn't
exist. But there's technically no reason to require guest-contig
memory for xen buffer sharing using grants.

Given all that, the xen-front cma support is not needed and should be
removed.

c575b7eeb8 drm/xen-front: Add support for Xen PV display frontend
Add support for Xen para-virtualized frontend display driver.
Accompanying backend [1] is implemented as a user-space application
and its helper library [2], capable of running as a Weston client
or DRM master.
Configuration of both backend and frontend is done via
Xen guest domain configuration options [3].

Driver limitations:
 1. Only primary plane without additional properties is supported.
 2. Only one video mode supported which resolution is configured
    via XenStore.
 3. All CRTCs operate at fixed frequency of 60Hz.

1. Implement Xen bus state machine for the frontend driver according to
the state diagram and recovery flow from display para-virtualized
protocol: xen/interface/io/displif.h.

2. Read configuration values from Xen store according
to xen/interface/io/displif.h protocol:
  - read connector(s) configuration
  - read buffer allocation mode (backend/frontend)

3. Handle Xen event channels:
  - create for all configured connectors and publish
    corresponding ring references and event channels in Xen store,
    so backend can connect
  - implement event channels interrupt handlers
  - create and destroy event channels with respect to Xen bus state

4. Implement shared buffer handling according to the
para-virtualized display device protocol at xen/interface/io/displif.h:
  - handle page directories according to displif protocol:
    - allocate and share page directories
    - grant references to the required set of pages for the
      page directory
  - allocate xen balllooned pages via Xen balloon driver
    with alloc_xenballooned_pages/free_xenballooned_pages
  - grant references to the required set of pages for the
    shared buffer itself
  - implement pages map/unmap for the buffers allocated by the
    backend (gnttab_map_refs/gnttab_unmap_refs)

5. Implement kernel modesetiing/connector handling using
DRM simple KMS helper pipeline:

- implement KMS part of the driver with the help of DRM
  simple pipepline helper which is possible due to the fact
  that the para-virtualized driver only supports a single
  (primary) plane:
  - initialize connectors according to XenStore configuration
  - handle frame done events from the backend
  - create and destroy frame buffers and propagate those
    to the backend
  - propagate set/reset mode configuration to the backend on display
    enable/disable callbacks
  - send page flip request to the backend and implement logic for
    reporting backend IO errors on prepare fb callback

- implement virtual connector handling:
  - support only pixel formats suitable for single plane modes
  - make sure the connector is always connected
  - support a single video mode as per para-virtualized driver
    configuration

6. Implement GEM handling depending on driver mode of operation:
depending on the requirements for the para-virtualized environment,
namely requirements dictated by the accompanying DRM/(v)GPU drivers
running in both host and guest environments, number of operating
modes of para-virtualized display driver are supported:
 - display buffers can be allocated by either
   frontend driver or backend
 - display buffers can be allocated to be contiguous
   in memory or not

Note! Frontend driver itself has no dependency on contiguous memory for
its operation.

6.1. Buffers allocated by the frontend driver.

The below modes of operation are configured at compile-time via
frontend driver's kernel configuration.

6.1.1. Front driver configured to use GEM CMA helpers
     This use-case is useful when used with accompanying DRM/vGPU driver
     in guest domain which was designed to only work with contiguous
     buffers, e.g. DRM driver based on GEM CMA helpers: such drivers can
     only import contiguous PRIME buffers, thus requiring frontend driver
     to provide such. In order to implement this mode of operation
     para-virtualized frontend driver can be configured to use
     GEM CMA helpers.

6.1.2. Front driver doesn't use GEM CMA
     If accompanying drivers can cope with non-contiguous memory then, to
     lower pressure on CMA subsystem of the kernel, driver can allocate
     buffers from system memory.

Note! If used with accompanying DRM/(v)GPU drivers this mode of operation
may require IOMMU support on the platform, so accompanying DRM/vGPU
hardware can still reach display buffer memory while importing PRIME
buffers from the frontend driver.

6.2. Buffers allocated by the backend

This mode of operation is run-time configured via guest domain
configuration through XenStore entries.

For systems which do not provide IOMMU support, but having specific
requirements for display buffers it is possible to allocate such buffers
at backend side and share those with the frontend.
For example, if host domain is 1:1 mapped and has DRM/GPU hardware
expecting physically contiguous memory, this allows implementing
zero-copying use-cases.

Note, while using this scenario the following should be considered:
  a) If guest domain dies then pages/grants received from the backend
     cannot be claimed back
  b) Misbehaving guest may send too many requests to the
     backend exhausting its grant references and memory
     (consider this from security POV).

Note! Configuration options 1.1 (contiguous display buffers) and 2
(backend allocated buffers) are not supported at the same time.

7. Handle communication with the backend:
 - send requests and wait for the responses according
   to the displif protocol
 - serialize access to the communication channel
 - time-out used for backend communication is set to 3000 ms
 - manage display buffers shared with the backend

bbeba09fc8 drm/docs: Document "scaling mode" property better
Move it out of the csv dungeon.

While at it add the missing link to the helper functions for setting
up the "panel rotation" property.

Also OCD how we list enum property values and their corresponding docs.
Going for a nest definition list seams cleanest, no need for also making
it an uordered list.

3f0df756b6 drm/docs: Discourage adding more to kms-properties.csv
Motivated by patch review.

The table is really hard to read in source form, hard to edit, and
we've moved away to more focused sections about specific features and
how they're exposed in properties.

Those sections can then more easily enumerate options, link to helper
functions and other parts of the docs. All things that get ugly real
fast in the docs.

af2e01da34 docs: fix, intel_guc_loader.c has been moved to intel_guc_fw.c
With commit d9e2e0143c the 'GuC-specific firmware loader' doc
section was removed from intel_guc_loader.c without a
replacement.  So lets remove it from the Kernel-doc::

  .. kernel-doc:: drivers/gpu/drm/i915/intel_guc_loader.c
     :doc: GuC-specific firmware loader

With commit e8668bbcb0 intel_guc_loader.c was renamed to to
intel_guc_fw.c and to name just one, intel_guc_init_hw() was
renamed to intel_guc_fw_upload(). Since we get errors in the

5fca5ece6a drm/doc: Move legacy kms helpers to the very end
We don't want people to accidentally stumble over there.

Also rename the plane helpers to legacy plane helpers. After Ville's
patch to make the clipping helper atomic and move it to
drm_atomic_helper.c there's nothing left in there that should be
useful for modern drivers.

v2: Laurent had a few questions around how state is added to
drm_atomic_state, tried to clarify that. And spotted another sentence
where the docs suggested subclassing.

v3: Small polish (Alex).

da6c059697 drm/atomic: document how to handle driver private objects
DK put some nice docs into the commit introducing driver private
state, but in the git history alone it'll be lost.

Also, since Ville remove the void* usage it's a good opportunity to
give the driver private stuff some tlc on the doc front.

Finally try to explain why the "let's just subclass drm_atomic_state"
approach wasn't the greatest, and annotate all those functions as
deprecated in favour of more standardized driver private states. Also
note where we could/should extend driver private states going forward
(atm neither locking nor synchronization is handled in core/helpers,
which isn't really all that great).

v2: Spelling and phrasing improvements (Alex, DK).

404d1a3edc drm: Add panel orientation quirks, v6.
Some x86 clamshell design devices use portrait tablet screens and a display
engine which cannot rotate in hardware, so the firmware just leaves things
as is and we cannot figure out that the display is oriented non upright
from the hardware.

So at least on x86, we need a quirk table for this. This commit adds a DMI
based quirk table which is initially populated with 5 such devices: Asus
T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17.

This quirk table will be used by the drm code to let userspace know that
the display is not mounted upright inside the devices case through a new
panel orientation drm-connector property, as well as to tell fbcon to
rotate the console so that it shows the right way up.

Changes in v5:
-Add a kernel-doc comment documenting drm_get_panel_orientation_quirk()
-Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop,
 keeping only the (identical) sys_vendor and product_name matches.
 This is necessary because an older version of the bios has
 board_vendor set to VOIS instead of VIOS

Changes in v6:
-Add reference to added kernel-docs in Documentation/gpu/drm-kms-helpers.rst

Merge tag 'drm-for-v4.15-amd-dc' of git://people.freedesktop.org/~airlied/linux

Pull amdgpu DC display code for Vega from Dave Airlie:
 "This is the pull request for the AMD DC (display code) layer which is
  a requirement to program the display engines on the new Vega and Raven
  based GPUs. It also contains support for all amdgpu supported GPUs
  (CIK, VI, Polaris), which has to be enabled. It is also a kms atomic
  modesetting compatible driver (unlike the current in-tree display
  code).

  I've kept it separate from drm-next because it may have some things
  that cause you to reject it.

  Background story:

  AMD have an internal team creating a shared OS codebase for display at
  hw bring up time using information from their hardware teams. This
  process doesn't lead to the most Linux friendly/looking code but we
  have worked together on cleaning a lot of it up and dealing with
  sparse/smatch/checkpatch, and having their team internally adhere to
  Linux coding standards.

  This tree is a complete history rebased since they started opening it,
  we decided not to squash it down as the history may have some value.
  Some of the commits therefore might not reach kernel standards, and we
  are steadily training people in AMD to better write commit msgs.

  There is a major bunch of generated bandwidth calculation and
  verification code that comes from their hardware team. On Vega and
  before this is float calculations, on Raven (DCN10) this is double
  based. They do the required things to do FP in the kernel, and I could
  understand this might raise some issues. Rewriting the bandwidth would
  be a major undertaken in reverification, it's non-trivial to work out
  if a display can handle the complete set of mode information thrown at
  it.

  Future story:

  There is a TODO list with this, and it address most of the remaining
  things that would be nice to refine/remove. The DCN10 code is still
  under development internally and they push out a lot of patches quite
  regularly and are supporting this code base with their display team. I
  think we've reached the point where keeping it out of tree is going to
  motivate distributions to start carrying the code, so I'd prefer we
  get it in tree. I think this code is slightly better than STAGING
  quality but not massively so, I'd really like to see that float/double
  magic gone and fixed point used, but AMD don't seem to think the
  accuracy and revalidation of the code is worth the effort"

b9e56e41e0 Merge branch 'drm-next-4.15-dc' of git://people.freedesktop.org/~agd5f/linux into drm-next
Initial pull request for DC support.  We've completed a substantial amount of
the cleanup and restructuring in our TODO.  There are a few additional
cleanups that we are continuing to work on, but I don't think there are any
showstoppers remaining. We've tried to maintain most of the history for bisect
purposes.  Harry made sure all the commits build.  We've enabled DC for vega10
and Raven.  Pre-vega10 parts can be enabled via module parameter (amdgpu.dc=1),
but are not enabled by default at this point until we get further testing
upstream.

This code provides atomic modesetting support for DCE8 (CIK), DCE10 (Tonga,
Fiji), DCE11 (CZ, ST, Polaris), DCE12 (vega10), and DCN1 (RV) including
HDMI and DP audio, DP MST, and many other advanced display features.

+

Latest cleanups for DC from you and Harry.  Note that there is some
flickering on some older asics with this branch due to a regression in powerplay
that has already been fixed and will be included in my next non-DC pull request
next week.

179c02fe90 drm/tve200: Add new driver for TVE200
This adds a new DRM driver for the Faraday Technology TVE200
block. This "TV Encoder" encodes a ITU-T BT.656 stream and can
be found in the StorLink SL3516 (later Cortina Systems CS3516)
as well as the Grain Media GM8180.

I do not have definitive word from anyone at Faraday that this
IP block is theirs, but it bears the hallmark of their 3-digit
version code (200) and is used in two SoCs from completely
different companies. (Grain Media was fully owned by Faraday
until it was transferred to NovoTek this january, and
Faraday did lots of work on the StorLink SoCs.)

The D-Link DIR-685 uses this in connection with the Ilitek
ILI9322 panel driver that supports BT.656 input, while the
GM8180 apparently has been used with the Cirrus Logic CS4954
digital video encoder. The oldest user seems to be
something called Techwall 2835.

This driver is heavily inspired by Eric Anholt's PL111
driver and therefore I have mentioned all the ancestor authors
in the header file.

735f463af7 Merge tag 'drm-intel-next-2017-08-18' of git://anongit.freedesktop.org/git/drm-intel into drm-next
Final pile of features for 4.14

- New ioctl to change NOA configurations, plus prep (Lionel)
- CCS (color compression) scanout support, based on the fancy new
  modifier additions (Ville&Ben)
- Document i915 register macro style (Jani)
- Many more gen10/cnl patches (Rodrigo, Pualo, ...)
- More gpu reset vs. modeset duct-tape to restore the old way.
- prep work for cnl: hpd_pin reorg (Rodrigo), support for more power
  wells (Imre), i2c pin reorg (Anusha)
- drm_syncobj support (Jason Ekstrand)
- forcewake vs gpu reset fix (Chris)
- execbuf speedup for the no-relocs fastpath, anv/vk low-overhead ftw (Chris)
- switch to idr/radixtree instead of the resizing ht for execbuf id->vma
  lookups (Chris)

gvt:
- MMIO save/restore optimization (Changbin)
- Split workload scan vs. dispatch for more parallel exec (Ping)
- vGPU full 48bit ppgtt support (Joonas, Tina)
- vGPU hw id expose for perf (Zhenyu)

Bunch of work all over to make the igt CI runs more complete/stable.
Watch https://intel-gfx-ci.01.org/tree/drm-tip/shards-all.html for
progress in getting this ready. Next week we're going into production
mode (i.e. will send results to intel-gfx) on hsw, more platforms to
come.

Also, a new maintainer tram, I'm stepping out. Huge thanks to Jani for
being an awesome co-maintainer the past few years, and all the best
for Jani, Joonas&Rodrigo as the new maintainers!

what the most common existing style is.

forward.

Start a new style section in the i915 document to bolt the register

f89823c212 drm/i915/perf: Implement I915_PERF_ADD/REMOVE_CONFIG interface
The motivation behind this new interface is expose at runtime the
creation of new OA configs which can be used as part of the i915 perf
open interface. This will enable the kernel to learn new configs which
may be experimental, or otherwise not part of the core set currently
available through the i915 perf interface.

v2: Drop DRM_ERROR for userspace errors (Matthew)
    Add padding to userspace structure (Matthew)
    s/guid/uuid/ (Matthew)

v3: Use u32 instead of int to iterate through registers (Matthew)

v4: Lock access to dynamic config list (Lionel)

v5: by Matthew:
    Fix uninitialized error values
    Fix incorrect unwiding when opening perf stream
    Use kmalloc_array() to store register
    Use uuid_is_valid() to valid config uuids
    Declare ioctls as write only
    Check padding members are set to 0
    by Lionel:
    Return ENOENT rather than EINVAL when trying to remove non
    existing config

v6: by Chris:
    Use ref counts for OA configs
    Store UUID in drm_i915_perf_oa_config rather then using pointer
    Shuffle fields of drm_i915_perf_oa_config to avoid padding

v7: by Chris
    Rename uapi pointers fields to end with '_ptr'

v8: by Andrzej, Marek, Sebastian
    Update register whitelisting
    by Lionel
    Add more register names for documentation
    Allow configuration programming in non-paranoid mode
    Add support for value filter for a couple of registers already

0cac6ac198 drm: todo: Avoid accidental crossreferences
RST uses underscores at the end of words to create crossreferences and
it will accidentally try to link to tinydrm_ and drm_fb_ targets from

Use backslashes to escape the special meaning of the underscore.

57d30230c5 drm/doc: vblank cleanup
Unify and review everything, plus make sure it's all correct markup.
Drop the kernel-doc for internal functions. Also rework the overview
section, it's become rather outdated.

Unfortuantely the kernel-doc in drm_driver isn't rendered yet, but
that will change as soon as drm_driver is kernel-docified properly.

Also document properly that drm_vblank_cleanup is optional, the core
calls this already.

v2: Make it clear that cleanup happens in drm_dev_fini for drivers
with their own ->release callback (Thierry).

e9083420bb drm: introduce sync objects (v4)
Sync objects are new toplevel drm object, that contain a
pointer to a fence. This fence can be updated via command
submission ioctls via drivers.

There is also a generic wait obj API modelled on the vulkan
wait API (with code modelled on some amdgpu code).

These objects can be converted to an opaque fd that can be
passes between processes.

v2: rename reference/unreference to put/get (Chris)
fix leaked reference (David Zhou)
drop mutex in favour of cmpxchg (Chris)
v3: cleanups from danvet, rebase on drm_fops rename
check fd_flags is 0 in ioctls.
v4: export find/free, change replace fence to take a
syncobj. In order to support lookup first, replace
later semantics which seem in the end to be cleaner.

13dfc0540a drm/bridge: Refactor out the panel wrapper from the lvds-encoder bridge.
Many DRM drivers have common code to make a stub connector
implementation that wraps a drm_panel.  By wrapping the panel in a DRM
bridge, all of the connector code (including calls during encoder
enable/disable) goes away.

v2: Fix build with CONFIG_DRM=m, drop "dev" argument that should just
    be the panel's dev, move kerneldoc up a level and document
    _remove().
v3: Fix another breakage with CONFIG_DRM=m, fix breakage with
    CONFIG_OF=n, move protos under CONFIG_DRM_PANEL_BRIDGE, wrap a
    line.

bed41005e6 drm/pl111: Initial drm/kms driver for pl111
This is a modesetting driver for the pl111 CLCD display controller
found on various ARM platforms such as the Versatile Express. The
driver has only been tested on the bcm911360_entphn platform so far,
with PRIME-based buffer sharing between vc4 and clcd.

It reuses the existing devicetree binding, while not using quite as
many of its properties as the fbdev driver does (those are left for
future work).

v2: Nearly complete rewrite by anholt, cutting 2/3 of the code thanks
    to DRM core's excellent new helpers.
v3: Don't match pl110 any more, don't attach if we don't have a DRM
    panel, use DRM_GEM_CMA_FOPS, update MAINTAINERS, use the simple
    display helper, use drm_gem_cma_dumb_create (same as our wrapper).
v4: Change the driver's .name to not clash with fbdev in sysfs, drop
    platform alias, drop redundant "drm" in DRM driver name, hook up
    .prepare_fb to the CMA helper so that DMA fences should work.
v5: Move register definitions inside the driver directory, fix build
    in COMPILE_TEST and !AMBA mode.
v6: Drop TIM2_CLKSEL for now to be consistent with existing DT
    bindings, switch back to external register definitions.

2640981f36 drm: document drm_ioctl.[hc]
Also unify/merge with the existing stuff.

I was a bit torn where to put this, but in the end I decided to put
all the ioctl/sysfs/debugfs stuff into drm-uapi.rst. That means we
have a bit a split with the other uapi related stuff used internally,
like drm_file.[hc], but I think overall this makes more sense.

If it's too confusing we can always add more cross-links to make it
more discoverable. But the auto-sprinkling of links kernel-doc already
does seems sufficient.

Also for prettier docs and more cross-links, switch the internal
defines over to an enum, as usual.

v2: Update kerneldoc fro drm_compat_ioctl too (caught by 0day), plus a
bit more drive-by polish.

v3: Fix typo, spotted by xerpi on irc (Sergi).

v4: Add missing space in comment (Neil).
