Pull drm fixes from Dave Airlie: "Nothing too unusual here for rc2. Except the amdgpu DMCU firmware loading fix caused build breakage with a different set of Kconfig options. I've just reverted it for now until the AMD folks can rewrite it to avoid that problem. i915: - boosting fix - bump ready task fixes - GVT - reset fix, error return, TRTT handling fix amdgpu: - DMCU firmware loading fix - Polaris 10 pci id for kfd - picasso screen corruption fix - SR-IOV fixes - vega driver reload fixes - SMU locking fix - compute profile fix for kfd vmwgfx: - integer overflow fixes - dma sg fix sun4i: - HDMI phy fixes gma500: - LVDS detection fix panfrost: - devfreq selection fix" * tag 'drm-fixes-2019-05-24-1' of git://anongit.freedesktop.org/drm/drm: (32 commits) Revert "drm/amd/display: Don't load DMCU for Raven 1" drm/panfrost: Select devfreq drm/gma500/cdv: Check vbt config bits when detecting lvds panels drm/vmwgfx: integer underflow in vmw_cmd_dx_set_shader() leading to an invalid read drm/vmwgfx: NULL pointer dereference from vmw_cmd_dx_view_define() drm/vmwgfx: Use the dma scatter-gather iterator to get dma addresses drm/vmwgfx: Fix compat mode shader operation drm/vmwgfx: Fix user space handle equal to zero drm/vmwgfx: Don't send drm sysfs hotplug events on initial master set drm/i915/gvt: Fix an error code in ppgtt_populate_spt_by_guest_entry() drm/i915/gvt: do not let TRTTE and 0x4dfc write passthrough to hardware drm/i915/gvt: add 0x4dfc to gen9 save-restore list drm/i915/gvt: Tiled Resources mmios are in-context mmios for gen9+ drm/i915/gvt: use cmd to restore in-context mmios to hw for gen9 platform drm/i915/gvt: emit init breadcrumb for gvt request drm/amdkfd: Fix compute profile switching drm/amdgpu: skip fw pri bo alloc for SRIOV drm/amd/powerplay: fix locking in smu_feature_set_supported() drm/amdgpu/gmc9: set vram_width properly for SR-IOV drm/amdgpu/soc15: skip reset on init ...

/* TODO
- * Right now only scan LRI command on KBL and in inhibit context.
- * It's good enough to support initializing mmio by lri command in
- * vgpu inhibit context on KBL.
+ * In order to let workload with inhibit context to generate
+ * correct image data into memory, vregs values will be loaded to
+ * hw via LRIs in the workload with inhibit context. But as
+ * indirect context is loaded prior to LRIs in workload, we don't
+ * want reg values specified in indirect context overwritten by
+ * LRIs in workloads. So, when scanning an indirect context, we
+ * update reg values in it into vregs, so LRIs in workload with
+ * inhibit context will restore with correct values
