drm/vmwgfx: Fix an invalid read

2022-06-09T08:29:54+00:00

[ Upstream commit 10a26e0d5fc3574f63ce8a6cf28381b126317f40 ] vmw_move assumed that buffers to be moved would always be vmw_buffer_object's but after introduction of new placement for mob pages that's no longer the case. The resulting invalid read didn't have any practical consequences because the memory isn't used unless the object actually is a vmw_buffer_object. Fix it by moving the cast to the spot where the results are used.

drm/vmwgfx: validate the screen formats

2022-06-09T08:29:32+00:00

[ Upstream commit 8bb75aeb58bd688d70827ae179bd3da57b6d975b ] The kms code wasn't validating the modifiers and was letting through unsupported formats. rgb8 was never properly supported and has no matching svga screen target format so remove it. This fixes format/modifier failures in kms_addfb_basic from IGT.

drm/vmwgfx: Disable command buffers on svga3 without gbobjects

2022-05-13T14:29:36+00:00

With very limited vram on svga3 it's difficult to handle all the surface migrations. Without gbobjects, i.e. the ability to store surfaces in guest mobs, there's no reason to support intermediate svga2 features, especially because we can fall back to fb traces and svga3 will never support those in-between features. On svga3 we wither want to use fb traces or screen targets (i.e. gbobjects), nothing in between. This fixes presentation on a lot of fusion/esxi tech previews where the exposed svga3 caps haven't been finalized yet.

drm/vmwgfx: Initialize drm_mode_fb_cmd2

2022-05-13T14:29:24+00:00

Transition to drm_mode_fb_cmd2 from drm_mode_fb_cmd left the structure unitialized. drm_mode_fb_cmd2 adds a few additional members, e.g. flags and modifiers which were never initialized. Garbage in those members can cause random failures during the bringup of the fbcon. Initializing the structure fixes random blank screens after bootup due to flags/modifiers mismatches during the fbcon bring up.

drm/vmwgfx: Fix fencing on SVGAv3

2022-05-13T14:29:13+00:00

Port of the vmwgfx to SVGAv3 lacked support for fencing. SVGAv3 removed FIFO's and replaced them with command buffers and extra registers. The initial version of SVGAv3 lacked support for most advanced features (e.g. 3D) which made fences unnecessary. That is no longer the case, especially as 3D support is being turned on. Switch from FIFO commands and capabilities to command buffers and extra registers to enable fences on SVGAv3.

drm/vmwgfx: Fix gem refcounting and memory evictions

2022-04-21T01:30:43+00:00

v2: Add the last part of the ref count fix which was spotted by Philipp Sieweck where the ref count of cpu writers is off due to ERESTARTSYS or EBUSY during bo waits. The initial GEM port broke refcounting on shareable (prime) surfaces and memory evictions. The prime surfaces broke because the parent surfaces weren't increasing the ref count on GEM surfaces, which meant that the memory backing textures could have been deleted while the texture was still accessible. The evictions broke due to a typo, the code was supposed to exit if the passed buffers were not vmw_buffer_object not if they were. They're tied because the evictions depend on having memory to actually evict. This fixes crashes with XA state tracker which is used for xrender acceleration on xf86-video-vmware, apps/tests which use a lot of memory (a good test being the piglit's streaming-texture-leak) and desktops.
