[PATCH v4.9.y 00/42] arm64 spectre patches

by Mark Rutland

Hi Greg, These patches backport arm64 spectre mitigations to v4.9.y (based on 4.9.93). I've done this backport from scratch, following the patches in the arm64 kpti branch [1] (which contrary to its name, also has spectre patches intended for backporting). To the best of my understanding the code is correct, in the context of the v4.9.y kernel, and I've tested the series on arm64 hardware available to me, using firmware with SMCCC 1.1 and branch predictor mitigations. I've Cc'd the usual suspects for testing. For anyone willing to test this, I've pushed this out to the stable/4.9.y/spectre branch of my kernel.org repo [2]. Note that I've left off the Qualcomm Falkor patches, as it was pointed out that necessary errata workarounds for Falkor were never backported, and thus I assume that no-one is using v4.9.y on Falkor parts. Shanker, do you have any idea whether people are using v4.9.y on Falkor? Thanks, Mark.

[PATCH] drm/i915/gvt: init mmio by lri command in vgpu inhibit context

by Weinan Li

commit cd7e61b93d068a80bfe6cb55bf00f17332d831a1 upstream. There is one issue relates to Coarse Power Gating(CPG) on KBL NUC in GVT-g, vgpu can't get the correct default context by updating the registers before inhibit context submission. It always get back the hardware default value unless the inhibit context submission happened before the 1st time forcewake put. With this wrong default context, vgpu will run with incorrect state and meet unknown issues. The solution is initialize these mmios by adding lri command in ring buffer of the inhibit context, then gpu hardware has no chance to go down RC6 when lri commands are right being executed, and then vgpu can get correct default context for further use. v3: - fix code fault, use 'for' to loop through mmio render list(Zhenyu) v4: - save the count of engine mmio need to be restored for inhibit context and refine some comments.
