2020-05-08drm/i915/gvt: Support PPGTT table load commandZhenyu Wang1-0/+45
The PPGTT in context image can be overridden by LRI cmd with another PPGTT's pdps. In such case, the load mm is used instead of the one in the context image. So we need to load its shadow mm in GVT and replace ppgtt pointers in command. This feature is used by guest IGD driver to share gfx VM between different contexts. Verified by IGT "gem_ctx_clone" test. v4: - consolidate shadow mm handlers (Yan) - fix cmd shadow mm pin error path v3: (Zhenyu Wang) - Cleanup PDP register offset check - Add debug check for guest context ppgtt update - Skip 3-level ppgtt guest handling code. The reason is that all guests now use 4-level ppgtt table and the only left case for 3-level table is ancient aliasing ppgtt case. But those guest kernel has no use of PPGTT LRI command. So 3-level ppgtt guest for this feature becomes simply un-testable. v2: (Zhenyu Wang) - Change to list for handling possible multiple ppgtt table loads in one submission. Make sure shadow mm is to replace for each one.

git://anongit.freedesktop.org/drm/drm-intel into drm-next Merge tag 'gvt-next-2018-09-04' drm-intel-next-2018-09-06-1: UAPI Changes: - GGTT coherency GETPARAM: GGTT has turned out to be non-coherent for some platforms, which we've failed to communicate to userspace so far. SNA was modified to do extra flushing on non-coherent GGTT access, while Mesa will mitigate by always requiring WC mapping (which is non-coherent anyway). - Neuter Resource Streamer uAPI: There never really were users for the feature, so neuter it while keeping the interface bits for compatibility. This is a long due item from past.

MI_NOOP is a common command appearing in almost all command buffers, put it into a fastpath can improve perfomance, especially in command buffers contains lots of MI_NOOPs (0s). Take glmark2 as an example, 3% performance increase is observed after introduced this patch. Meanwhile, in case where abundant in MI_NOOPs, up to 12% performance increase is measured. v2: use lowercase for index of MI_NOOP in cmd_info (zhenyu wang) Signed-off-by: Li Weinan <[email protected]> Signed-off-by: Zhao Yan <[email protected]> Signed-off-by: Zhenyu Wang <[email protected]>

Commit cd7e 61b9"init mmio by lri command in vgpu inhibit context" initializes registers saved/restored in context with its vreg value through lri command in ring buffer. It relies on vreg got updated on every guest access. There is a case found that Linux guest uses lri command in inhibit-ctx to update the register. This patch adds vreg update on this case. v2: move mmio_attribute functions to gvt.h (Zhenyu) v3: use mask_mmio_write in vreg update v4: refine codes and add more comments (Zhenyu) Fixes: cd7e61b9("drm/i915/gvt: init mmio by lri command in vgpu inhibit context") Signed-off-by: Hang Yuan <[email protected]> Signed-off-by: Weinan Li <[email protected]> Signed-off-by: Zhenyu Wang <[email protected]>
