" This is a bit more than I'd like to be pushing at this point in a
cycle, but it's a fairly important issue. There's been numerous
reports of more recent GP10[2467] boards failing to load, and I've
worked with NVIDIA FW engineers and tracked this down to the FW we've
been using not properly supporting the boards in question.
I've pushed an update to linux-firmware with the new FW version, which
unfortunately contains API changes vs the older firmware.
This series teaches the ACR subsystem inside nouveau enough to be able
to deal with supporting multiple incompatible FW revisions, and adds
support to the relevant chipsets for loading the newer FW revision, if
it's available."

Some newer boards with these chipsets aren't compatible with the prior
version of the SEC2 FW, and fail to load as a result.
This newer FW is actually the one we already use on >=GP108.
Unfortunately, there are interface differences in GP108's FW, making it
impossible to simply move files around in linux-firmware to solve this.
We need to be able to keep compatibility with all linux-firmware/kernel
combinations, which means supporting both firmwares.

It's not enough to have per-falcon structures anymore, we have multiple

nv50_head_atomic_duplicate_state() makes a copy of nv50_head_atom
struct. This patch adds copying of struct member named "or", which
previously was left uninitialized in the duplicated structure.
Due to this bug, incorrect nhsync and nvsync values were sometimes used.
In my particular case, that lead to a mismatch between the output
resolution of the graphics device (GeForce GT 630 OEM) and the reported
input signal resolution on the display. xrandr reported 1680x1050, but
the display reported 1280x1024. As a result of this mismatch, the output
on the display looked like it was cropped (only part of the output was
actually visible on the display).
git bisect pointed to commit 2ca7fb5c1c ("drm/nouveau/kms/nv50: handle
SetControlOutputResource from head"), which added the member "or" to
nv50_head_atom structure, but forgot to copy it in
nv50_head_atomic_duplicate_state().

Modesetting only, still waiting on ACR/GR firmware from NVIDIA for Turing

HW has error checks in place which check that pixel depth is explicitly
provided on DP, while HDMI has a "default" setting that we use.
In multi-display configurations with identical modelines, but different
protocols (HDMI + DP, in this case), it was possible for the DP head to
get swapped to the head which previously drove the HDMI output, without
updating HeadSetControlOutputResource(), triggering the error check and
hanging the core update.

"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.

For a while, we've had the problem of i2c bus access not grabbing
a runtime PM ref when it's being used in userspace by i2c-dev, resulting
in nouveau spamming the kernel log with errors if anything attempts to
access the i2c bus while the GPU is in runtime suspend. An example:
[ 130.078386] nouveau 0000:01:00.0: i2c: aux 000d: begin idle timeout ffffffff
Since the GPU is in runtime suspend, the MMIO region that the i2c bus is
on isn't accessible. On x86, the standard behavior for accessing an
unavailable MMIO region is to just return ~0.
Except, that turned out to be a lie. While computers with a clean
concious will return ~0 in this scenario, some machines will actually
completely hang a CPU on certian bad MMIO accesses. This was witnessed
with someone's Lenovo ThinkPad P50, where sensors-detect attempting to
access the i2c bus while the GPU was suspended would result in a CPU
hang:

watchdog: BUG: soft lockup - CPU#5 stuck for 23s! [sensors-detect:12438]
Yikes! While I wanted to try to make it so that accessing an i2c bus on
nouveau would wake up the GPU as needed, airlied pointed out that pretty
much any usecase for userspace accessing an i2c bus on a GPU (mainly for
the DDC brightness control that some displays have) is going to only be
useful while there's at least one display enabled on the GPU anyway, and
the GPU never sleeps while there's displays running.
Since teaching the i2c bus to wake up the GPU on userspace accesses is a
good deal more difficult than it might seem, mostly due to the fact that
we have to use the i2c bus during runtime resume of the GPU, we instead
opt for the easiest solution: don't let userspace access i2c busses on
the GPU at all while it's in runtime suspend.
Changes since v1:
* Also disable i2c busses that run over DP AUX

Commit 3a6536c51d ("drm/nouveau: Intercept ACPI_VIDEO_NOTIFY_PROBE")
added a definition of ACPI_VIDEO_NOTIFY_PROBE because <acpi/video.h> didn't
supply one. Later, commit eff4a751cc ("ACPI / video: Move
ACPI_VIDEO_NOTIFY_* defines to acpi/video.h") moved ACPI_VIDEO_NOTIFY_PROBE
and other definitions to <acpi/video.h>, so the copy in nouveau_display.c
is now unnecessary.
Remove the unnecessary definition from nouveau_display.c.

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5b
("kbuild: do not drop -I without parameter").

There was a nouveau DDX that relied on legacy context ioctls to work,

drm: Turn off Legacy Context Functions
The context functions are not used by the i915 driver and should not
be used by modeset drivers. These driver functions contain several bugs
and security holes. This change makes these functions optional can be
turned on by a setting, they are turned off by default for modeset
driver with the exception of the nouvea driver that may require them with
an old version of libdrm.

This changes the fb name from "nouveaufb" to "nouveaudrmfb".
Aside: I wonder whether the in_interrupt() check is good enough for
the nouveau acceleration. Cargo-cult says drm_can_sleep() is needed,
which isn't actually working if you pick a .config without PREEMPT.
For the generic fbdev defio support we've gone with offloading
everything to a worker. For the non-accel callbacks (set_par, blank
and friends) checking for oops_in_progress is good enough to catch all
the evil calling contexts.

KMS drivers really should all be able to restore their display state
on resume without fbcon helping out. So make this the default.
Since I'm not entirely foolish, make it only a default, which drivers
can still override. That way when the inevitable regression report
happens I can fix things up with a one-liner plus FIXME comment that
someone should fix up the suspend/resume code in that driver.
But at least all new drivers won't be broken by accident as soon as
you turn off fbcon because "suspend/resume worked when I tested it".
