2025-10-06drm/vmwgfx: Fix a null-ptr access in the cursor snooperZack Rusin1-5/+12
Check that the resource which is converted to a surface exists before trying to use the cursor snooper on it. vmw_cmd_res_check allows explicit invalid (SVGA3D_INVALID_ID) identifiers because some svga commands accept SVGA3D_INVALID_ID to mean "no surface", unfortunately functions that accept the actual surfaces as objects might (and in case of the cursor snooper, do not) be able to handle null objects. Make sure that we validate not only the identifier (via the vmw_cmd_res_check) but also check that the actual resource exists before trying to do something with it.

2025-07-17Revert "drm/vmwgfx: Use dma_buf from GEM object instance"Thomas Zimmermann1-3/+3
This reverts commit aec8a40228acb385d60feec59b54573d307e60f3. The dma_buf field in struct drm_gem_object is not stable over the object instance's lifetime. The field becomes NULL when user space releases the final GEM handle on the buffer object. This resulted in a NULL-pointer deref. Workarounds in commit 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers") and commit f6bfc9afc751 ("drm/framebuffer: Acquire internal references on GEM handles") only solved the problem partially. They especially don't work for buffer objects without a DRM framebuffer associated. Hence, this revert to going back to using .import_attach->dmabuf.

Commit 81256a50aa0f ("x86/mm: Make memremap(MEMREMAP_WB) map memory as encrypted by default") changed the default behavior of memremap(MEMREMAP_WB) and started mapping memory as encrypted. The driver requires the fifo memory to be decrypted to communicate with the host but was relaying on the old default behavior of memremap(MEMREMAP_WB) and thus broke. Fix it by explicitly specifying the desired behavior and passing MEMREMAP_DEC to memremap.

2025-06-17drm/vmwgfx: Implement dma_fence_ops properlyIan Forbes5-500/+97
vmwgfx's fencing predates dma_fence and as a result dma_fence_ops was never properly implemented, especially with respect to enabling signaling. Because of this dma_fence callbacks don't work properly. This change implements enable_signaling properly so that dma_fence callbacks now work as expected. It also removes vmwgfx's custom implementation of fence callbacks and removes vmwgfx's custom dma_fence_ops::wait function which is no longer necessary now that enable_signaling works.

There was a possible race in vmw_update_seqno. Because of this race it was possible for last_read_seqno to go backwards. Remove this function and replace it with vmw_update_fences which now sets and returns the last_read_seqno while holding the fence lock. This serialization via the fence lock ensures that last_read_seqno is monotonic again.

On hotplug ports using in-band presence detect, the reset causes a Presence Detect Changed event, which mistakenly caused teardown and re-enumeration of the device. Drivers may need to annotate code that resets their device (Lukas Wunner) Virtualization: - Add an ACS quirk for Loongson Root Ports that don't advertise ACS but don't allow peer-to-peer transactions between Root Ports;
