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) Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Sumit Semwal <sumit.semwal@linaro.org> Cc: "Christian König" <christian.koenig@amd.com> Cc: David Stevens <stevensd@chromium.org> Cc: linux-media@vger.kernel.org Cc: linaro-mm-sig@lists.linaro.org Link: https://patchwork.freedesktop.org/patch/msgid/20210115164739.3958206-1-daniel.vetter@ffwll.ch

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.

Other way round is a bit inconsistent (but not buggy in any kind). This is prep work so that ttm_resource_manager_set_used can assert that the resource manager is empty.

This isn't actually protecting anything becuase: - 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.

The GEM mmap code relies on the GEM object's mmap callback to set the VMA's vm_ops field. This is easily forgotten and already led to a memory leak in the CMA helpers. Instead set the vm_ops field in the DRM core code to the GEM object's value. Drivers with different needs can override this in their mmap callback. v2: * support (vm_ops == NULL) if mmap is given; required by VRAM helpers Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Fixes: f5ca8eb6 ("drm/cma-helper: Implement mmap as GEM CMA object functions") Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reported-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> Tested-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Eric Anholt <eric@anholt.net> Cc: dri-devel@lists.freedesktop.org Link: https://patchwork.freedesktop.org/patch/msgid/20210115093038.10345-1-tzimmermann@suse.de

Currently the kmalloc allocation for config is not being null checked and could potentially lead to a null pointer dereference. Fix this by adding the missing null check.

The function vc4_prime_import_sg_table() is an otherwise empty wrapper around CMA's drm_gem_cma_prime_import_sg_table(). Removing it in favor of the latter allows to initialize vc4_drm_driver with CMA's initializer macro.

The new >8k CEA modes have dotclocks reaching 5.94 GHz, which means our clock*1000 will now overflow the 32bit unsigned integer. Switch to 64bit maths to avoid it.

We can't be setting the display_id register to an invalid value because that makes our device reset the fb which causes nasty flicker (due to destruction and creation of a new fb). Also we can't be using the BITS_PER_PIXEL register if the 8BIT_EMULATION is not supported.

Lets try to cleanup the usage of the term FIFO which we used for both our MMIO based cmd queue processing and for general command processing which could have been using command buffers interface. We're going to rename the functions which are processing commands (and work either via MMIO or command buffers) as _cmd_ and functions which operate on the MMIO based commands as FIFO to match the SVGA device naming.

Throttling was used before fencing to implement early vsync support in the xorg state tracker a long time ago. The xorg state tracker has been removed years ago and no one else has ever used throttling. It's time to remove this code, it hasn't been used or tested in years.

Going forward the svga device might reuse mmio for general register accesses, in order to prepare for that we need to cleanup our naming and handling of fifo specific mmio reads and writes. As part of this work lets switch to managed mapping of the fifo mmio to make the error handling cleaner.
