drm: Upcast struct drm_device.dev to struct pci_device; replace pdev

We have DRM drivers based on USB, SPI and platform devices. All of them
are fine with storing their device reference in struct drm_device.dev.
PCI devices should be no exception. Therefore struct drm_device.pdev is
deprecated.

Instead upcast from struct drm_device.dev with to_pci_dev(). PCI-specific
code can use dev_is_pci() to test for a PCI device. This patch changes
the DRM core code and documentation accordingly.

Daniel Vetter [Fri, 15 Jan 2021 16:47:39 +0000 (17:47 +0100)]
dma-buf: Add debug option

We have too many people abusing the struct page they can get at but
really shouldn't in importers. Aside from that the backing page might
simply not exist (for dynamic p2p mappings) looking at it and using it
e.g. for mmap can also wreak the page handling of the exporter
completely. Importers really must go through the proper interface like
dma_buf_mmap for everything.

I'm semi-tempted to enforce this for dynamic importers since those
really have no excuse at all to break the rules.

Unfortuantely we can't store the right pointers somewhere safe to make
sure we oops on something recognizable, so best is to just wrangle
them a bit by flipping all the bits. At least on x86 kernel addresses
have all their high bits sets and the struct page array is fairly low
in the kernel mapping, so flipping all the bits gives us a very high
pointer in userspace and hence excellent chances for an invalid
dereference.

v2: Add a note to the @map_dma_buf hook that exporters shouldn't do
fancy caching tricks, which would blow up with this address scrambling
trick here (Chris)

Enable by default when CONFIG_DMA_API_DEBUG is enabled.

v3: Only one copy of the mangle/unmangle code (Christian)

v4: #ifdef, not #if (0day)

v5: sg_table can also be an ERR_PTR (Chris, Christian)

drm/ttm: WARN_ON non-empty lru when disabling a resource manager

ttm_resource_manager->use_type is only used for runtime changes by
vmwgfx. I think ideally we'd push this functionality into drivers -
ttm itself does not provide any locking to guarantee this is safe, so
the only way this can work at runtime is if the driver does provide
additional guarantees. vwmgfx does that through the
vmw_private->reservation_sem. Therefore supporting this feature in
shared code feels a bit misplaced.

As a first step add a WARN_ON to make sure the resource manager is
empty. This is just to make sure I actually understand correctly what
vmwgfx is doing, and to make sure an eventual subsequent refactor
doesn't break anything.

This check should also be useful for other drivers, to make sure they
haven't leaked anything.

- when running, ttm_resource_manager->use_type is protected through
  vmw_private->reservation_semaphore against concurrent execbuf or
  well anything else that might evict or reserve buffers
- during suspend/resume there's nothing else running, hence
  vmw_pm_freeze and vmw_pm_restore do not need to take the same lock.
- this also holds for the SVGA_REG_ENABLE register write

Hence it is safe to just remove that spinlock.

drm/vc4: Move mmap implementation into GEM object function

Moving vc4's mmap code from vc4_mmap() into a GEM object function
allows for the use drm_gem_mmap() and drm_gem_prime_mmap(). The content
of vc4_drm_fpos can then be generated by DEFINE_DRM_GEM_FOPS().

The actual mmap implementation is just a check if the BO is a validated
shader plus the default CMA mmap code.

Standard DRM panel driver for DSI command mode panel used by omapfb2 is also
available now. Just like the other panels its module name clashes with the
module from drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated
omapfb2 fbdev driver. As omapfb2 can only be compiled when the omapdrm driver
is disabled, and the DRM panel drivers are useless in that case, make the
omapfb2 panel depend on the standard DRM panels being disabled to fix
the name clash.
