On bochs DRM driver, the execution of "setterm --blank force" results
in a frozen screen instead of a blank screen. It's due to the lack of
the screen blanking support in its code.
Actually, the QEMU bochs vga side can switch to the blanking mode when
the bit 0x20 is cleared on VGA_ATT_IW register (0x3c0), which updates
ar_index in QEMU side. So, essentially, we'd just need to clear the
bit at pipe disable callback; that's what this patch does essentially.
However, a tricky part is that the access via VGA_ATT_IW is done in
"flip-flop"; the first write is for index and the second write is for
the data like palette. Meanwhile, in the current bochs DRM driver,
the flip-flop wasn't considered, and it calls only the register update
once with the value 0x20.
The spec and the actual VGA implementation in QEMU suggests that the
flip flop flag is discarded by reading the CRTC index register
(VGA_IS1_RC, 0x3da). So, in this patch, we add the helper to read a
byte and the call to clear the flip flop flag before changing the
blank / unblank setup via VGA_ATT_IW register.
v1->v2:
* discard ar_flip_flop by reading 0x3da, add bochs_vga_readb()
* include video/vga.h for VGA register definitions
* move the blank/unblank code to bochs_hw_blank()

At least sparc64 requires I/O-specific access to framebuffers. This
patch updates the fbdev console accordingly.
For drivers with direct access to the framebuffer memory, the callback
functions in struct fb_ops test for the type of memory and call the rsp
fb_sys_ of fb_cfb_ functions. Read and write operations are implemented
internally by DRM's fbdev helper.
For drivers that employ a shadow buffer, fbdev's blit function retrieves
the framebuffer address as struct dma_buf_map, and uses dma_buf_map
interfaces to access the buffer.
The bochs driver on sparc64 uses a workaround to flag the framebuffer as
I/O memory and avoid a HW exception. With the introduction of struct
dma_buf_map, this is not required any longer. The patch removes the rsp
code from both, bochs and fbdev.
v7:
* use min_t(size_t,) (kernel test robot)
* return the number of bytes read/written, if any (fbdev testcase)
v5:
* implement fb_read/fb_write internally (Daniel, Sam)
v4:
* move dma_buf_map changes into separate patch (Daniel)
* TODO list: comment on fbdev updates (Daniel)

Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support.
Subsequent patch will address this.
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
maybe a bit too much, hence the num_ioctls assignment prevents a
const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
from me.
- legacy drivers, because legacy requires non-const drm_driver.
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else
is way too much).
v2: Fix one misplaced const static, should be static const (0day)

Merge tag 'v5.8' into drm-next
I need to backmerge 5.8 as I've got a bunch of fixes sitting

Signed-off-by: Dave Airlie <airlied@redhat.com>
Recent kernels have been reported to panic using the bochs_drm
framebuffer under qemu-system-sparc64 which was bisected to
commit 7a0483ac4f ("drm/bochs: switch to generic drm fbdev emulation").
The backtrace indicates that the shadow framebuffer copy in
drm_fb_helper_dirty_blit_real() is trying to access the real
framebuffer using a virtual address rather than use an IO access
typically implemented using a physical (ASI_PHYS) access on SPARC.
The fix is to replace the memcpy with memcpy_toio() from io.h.
memcpy_toio() uses writeb() where the original fbdev code
used sbus_memcpy_toio(). The latter uses sbus_writeb().
The difference between writeb() and sbus_memcpy_toio() is
that writeb() writes bytes in little-endian, where sbus_writeb() writes
bytes in big-endian. As endian does not matter for byte writes they are
the same. So we can safely use memcpy_toio() here.
Note that this only fixes bochs, in general fbdev helpers still have
issues with mixing up system memory and __iomem space. Fixing that will
require a lot more work.
v3:
- Improved changelog (Daniel)
- Added FIXME to fbdev_use_iomem (Daniel)
v2:
- Added missing __iomem cast (kernel test robot)
- Made changelog readable and fix typos (Mark)
- Add flag to select iomem - and set it in the bochs driver

Instead rely on the automatic clean, for which we just need to check

drmm_kzalloc.
This is made possible by a preceeding patch which added a drmm_

The bochs driver (and virtual hardware) requires buffer objects to
reside in video ram to display them to the screen. So it can not
display the framebuffer console because the respective buffer object
is permanently pinned in system memory.
Using a shadow buffer for the console solves this problem. The console
emulation will pin the buffer object only during updates from the shadow
buffer. Otherwise, the bochs driver can freely relocated the buffer
between system memory and video ram.

When unloading the bochs-drm driver, a warning message is printed by
drm_mode_config_cleanup() because a reference is still held to one of
the drm_connector structs.
Correct this by calling drm_atomic_helper_shutdown() in
bochs_pci_remove().

The data structure |struct drm_vram_mm| and its helpers replace bochs'
TTM-based memory manager. It's the same implementation; except for the
type names.
v5:
* set .llseek via DRM_VRAM_MM_FILE_OPERATIONS
v4:
* don't select DRM_TTM or DRM_VRAM_MM_HELPER
v3:
* use drm_gem_vram_mm_funcs
* convert driver to drm_device-based instance
v2:
* implement bochs_mmap() with drm_vram_mm_mmap()

A BO's address has to be at least the minimum offset. Sharing this
test in ttm_bo_mmap() removes code from drivers. A full buffer-address
validation is still done within drm_vma_offset_lockup_locked().

Most TTM drivers define the constant DRM_FILE_PAGE_OFFSET of the same
value. The only exception is vboxvideo, which is being converted to the
new offset by this patch. Unifying the constants in a single place
simplifies the driver code.
