2021-12-09drm/vmwgfx: Implement DRIVER_GEMZack Rusin1-7/+3
This is initial change adding support for DRIVER_GEM to vmwgfx. vmwgfx was written before GEM and has always used TTM. Over the years the TTM buffers started inherting from GEM objects but vmwgfx never implemented GEM making it quite awkward. We were directly setting variables in GEM objects to not make DRM crash. This change brings vmwgfx inline with other DRM drivers and allows us to use a lot of DRM helpers which have depended on drivers with GEM support. Due to historical reasons vmwgfx splits the idea of a buffer and surface which makes it a littly tricky since either one can be used in most of our ioctl's which take user space handles. For now our BO's are GEM objects and our surfaces are opaque objects which are backed by GEM objects. In the future I'd like to combine those into a single BO but we don't want to break any of our existing ioctl's so it will take time to do it in a non-destructive way.

2021-07-28drm/vmwgfx: Cleanup loggingZack Rusin1-4/+0
The code was using the old DRM logging functions, which made it hard to figure out what was coming from vmwgfx. The newer logging helpers include the driver name in the logs and make it explicit which driver they're coming from. This allows us to standardize our logging a bit and clean it up in the process. vmwgfx is a little special because technically the hardware it's running on can be anything from the last 12 years or so which is why we need to include capabilities in the logs in the first place or otherwise we'd have no way of knowing what were the capabilities of the platform the guest was running in.

2021-02-25drm: Use state helper instead of the plane state pointerMaxime Ripard1-1/+1
Many drivers reference the plane->state pointer in order to get the current plane state in their atomic_update or atomic_disable hooks, which would be the new plane state in the global atomic state since _swap_state happened when those hooks are run.

2019-04-08drm/vmwgfx: Be more restrictive when dirtying resourcesThomas Hellstrom1-1/+2
Currently we flag resources as dirty (GPU contents not yet read back to the backing MOB) whenever they have been part of a command stream. Obviously many resources can't be dirty and others can only be dirty when written to by the GPU. That is when they are either bound to the context as render-targets, depth-stencil, copy / clear destinations and stream-output targets, or similarly when there are corresponding views into them. So mark resources dirty only in these special cases. Context- and cotable resources are always marked dirty when referenced. This is important for upcoming emulated coherent memory, since we can avoid issuing automatic readbacks to non-dirty resources when the CPU tries to access part of the backing MOB.

2018-07-03drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_objectThomas Hellstrom1-50/+50
Initially vmware buffer objects were only used as DMA buffers, so the name DMA buffer was a natural one. However, currently they are used also as dumb buffers and MOBs backing guest backed objects so renaming them to buffer objects is logical. Particularly since there is a dmabuf subsystem in the kernel where a dma buffer means something completely different. This also renames user-space api structures and IOCTL names correspondingly, but the old names remain defined for now and the ABI hasn't changed. There are a couple of minor style changes to make checkpatch happy.

SOU primary plane prepare_fb hook depends upon dmabuf_size to pin up BO (and not call a new vmw_dmabuf_init) when a new fb size is same as current fb.

2018-03-22drm/vmwgfx: Unpin the screen object backup buffer when not usedThomas Hellstrom1-8/+21
We were relying on the pinned screen object backup buffer to be destroyed when not used. But if we hold a copy of the atomic state, like when hibernating, the backup buffer might not be destroyed since it's refcounted by the atomic state. This causes us to hibernate with a buffer pinned in VRAM. Fix this by only having the buffer pinned when it is actually used by a screen object.

2018-03-21drm/vmwgfx: Fix a destoy-while-held mutex problem.Thomas Hellstrom1-2/+3
When validating legacy surfaces, the backup bo might be destroyed at surface validate time. However, the kms resource validation code may have the bo reserved, so we will destroy a locked mutex. While there shouldn't be any other users of that mutex when it is destroyed, it causes a lock leak and thus throws a lockdep error. Fix this by having the kms resource validation code hold a reference to the bo while we have it reserved. We do this by introducing a validation context which might come in handy when the kms code is extended to validate multiple resources or buffers.

This will allow new members of that union to be added in the future without changing code related to the existing vbl event type.

This way, delivery doesn't need to have the crtc ID available. v2: * Remove 'dev' argument from create_vblank_event It wasn't being used anyways, and if we need it in the future, we can always get it from crtc->dev. * Check for MODESETTING before looking for crtc in queue_vblank_event UMS drivers will oops if we try to get a crtc, so make sure we're modesetting before we try to find a crtc_id to fill into the event.
