drm: introduce a capability flag for syncobj timeline support

2019-05-02T02:36:47Z

Unfortunately userspace users of this API cannot be publicly disclosed yet. This commit effectively disables timeline syncobj ioctls for all drivers. Each driver wishing to support this feature will need to expose DRIVER_SYNCOBJ_TIMELINE. v2: Add uAPI capability check (Christian) Signed-off-by: Lionel Landwerlin Reviewed-by: Christian König (v1) Cc: Dave Airlie Cc: Daniel Vetter Cc: Christian König Cc: Chunming Zhou Reviewed-by: Dave Airlie Reviewed-by: Chunming Zhou Signed-off-by: Dave Airlie Link: https://patchwork.freedesktop.org/patch/msgid/20190416125750.31370-1-lionel.g.landwerlin@intel.com

This time around it is a bunch of cleanup and fixes, expanding gpu "zap" shader support (so we can take the GPU out of secure mode on boot) to a6xx, and small UABI extension to support robustness (see mesa MR 673).

drm/msm/gpu: Add submit queue queries

2019-04-19T18:50:06Z

Add the capability to query information from a submit queue. The first available parameter is for querying the number of GPU faults (hangs) that can be attributed to the queue. This is useful for implementing context robustness. A user context can regularly query the number of faults to see if it is responsible for any and if so it can invalidate itself. This is also helpful for testing by confirming to the user driver if a particular command stream caused a fault (or not as the case may be). Signed-off-by: Jordan Crouse Signed-off-by: Rob Clark

drm/msm: add param to retrieve # of GPU faults (global)

2019-04-19T18:50:00Z

For KHR_robustness, userspace wants to know two things, the count of GPU faults globally, and the count of faults attributed to a given context. This patch providees the former, and the next patch provides the latter. Signed-off-by: Rob Clark Reviewed-by: Jordan Crouse

drm/msm/gpu: add per-process pagetables param

2019-04-19T18:49:42Z

For now it always returns '0' (false), but once the iommu work is in place to enable per-process pagetables we can update the value returned. Userspace needs to know this to make an informed decision about exposing KHR_robustness. Signed-off-by: Rob Clark Reviewed-by: Jordan Crouse

drm/i915: Introduce struct class_instance for engines across the uAPI

2019-04-17T06:25:42Z

SSEU reprogramming of the context introduced the notion of engine class and instance for a forwards compatible method of describing any engine beyond the old execbuf interface. We wish to adopt this class:instance description for more interfaces, so pull it out into a separate type for userspace convenience.
