2020-05-27T15:46:43Z

commit bc850943486887e3859597a266767f95db90aa72 upstream. We need to preserve fatal errors from fences that are being terminated as we hook them up.

drm/i915/gvt: Init DPLL/DDI vreg for virtual display instead of inheritance.

2020-05-27T15:46:43Z

commit f965b68188ab59a40a421ced1b05a2fea638465c upstream. Init value of some display vregs rea inherited from host pregs. When host display in different status, i.e. all monitors unpluged, different display configurations, etc., GVT virtual display setup don't consistent thus may lead to guest driver consider display goes malfunctional. The added init vreg values are based on PRMs and fixed by calcuation from current configuration (only PIPE_A) and the virtual EDID.

drm/etnaviv: fix perfmon domain interation

2020-05-27T15:46:41Z

commit 40b697e256ccdb88aaff424b44b4d300eb8460e8 upstream. The GC860 has one GPU device which has a 2d and 3d core. In this case we want to expose perfmon information for both cores. The driver has one array which contains all possible perfmon domains with some meta data - doms_meta. Here we can see that for the GC860 two elements of that array are relevant: doms_3d: is at index 0 in the doms_meta array with 8 perfmon domains doms_2d: is at index 1 in the doms_meta array with 1 perfmon domain The userspace driver wants to get a list of all perfmon domains and their perfmon signals. This is done by iterating over all domains and their signals. If the userspace driver wants to access the domain with id 8 the kernel driver fails and returns invalid data from doms_3d with and invalid offset. This results in: Unable to handle kernel paging request at virtual address 00000000 On such a device it is not possible to use the userspace driver at all. The fix for this off-by-one error is quite simple.

drm/amd/display: Prevent dpcd reads with passive dongles

drm/amd/display: add basic atomic check for cursor plane

2020-05-20T06:20:33Z

commit 626bf90fe03fa080d8df06bb0397c95c53ae8e27 upstream. This patch adds a basic cursor check when an atomic test-only commit is performed. The position and size of the cursor plane is checked. This should fix user-space relying on atomic checks to assign buffers to planes.

Make the "Reducing compressed framebufer size" message be DRM_INFO_ONCE()

2020-05-20T06:20:32Z

commit 82152d424b6cb6fc1ede7d03d69c04e786688740 upstream. This was sort of annoying me: random:~$ dmesg | tail -1 [523884.039227] [drm] Reducing the compressed framebuffer size. This may lead to less power savings than a non-reduced-size. Try to increase stolen memory size if available in BIOS. random:~$ dmesg | grep -c "Reducing the compressed" 47 This patch makes it DRM_INFO_ONCE() just like the similar message farther down in that function is pr_info_once().

drm/i915/gvt: Fix kernel oops for 3-level ppgtt guest

2020-05-20T06:20:24Z

[ Upstream commit 72a7a9925e2beea09b109dffb3384c9bf920d9da ] As i915 won't allocate extra PDP for current default PML4 table, so for 3-level ppgtt guest, we would hit kernel pointer access failure on extra PDP pointers. So this trys to bypass that now. It won't impact real shadow PPGTT setup, so guest context still works. This is verified on 4.15 guest kernel with i915.enable_ppgtt=1 to force on old aliasing ppgtt behavior.
