For use in the next patch, we want to acquire a wakeref without having to wake the device up -- i.e. only acquire the engine wakeref if the engine is already active. Signed-off-by:

Since the reset path wants to recover the engines itself, it only wants to reinitialise the hardware using i915_gem_init_hw().

Windows guest can't run after force-TDR with host log: ... gvt: vgpu 1: workload shadow ppgtt isn't ready gvt: vgpu 1: fail to dispatch workload, skip ... The error is raised by set_context_ppgtt_from_shadow(), when it checks and found the shadow_mm isn't marked as shadowed. In work thread before each submission, a shadow_mm is set to shadowed in: shadow_ppgtt_mm() <-intel_vgpu_pin_mm() <-prepare_workload() <-dispatch_workload() <-workload_thread() However checking whether or not shadow_mm is shadowed is prior to it: set_context_ppgtt_from_shadow() <-dispatch_workload() <-workload_thread() In normal case, create workload will check the existence of shadow_mm, if not it will create a new one and marked as shadowed. If already exist it will reuse the old one. Since shadow_mm is reused, checking of shadowed in set_context_ppgtt_from_shadow() actually always see the state set in creation, but not the state set in intel_vgpu_pin_mm(). When force-TDR, all engines are reset, since it's not dmlr level, all ppgtt_mm are invalidated but not destroyed. Invalidation will mark all reused shadow_mm as not shadowed but still keeps in ppgtt_mm_list_head. If workload submission phase those shadow_mm are reused with shadowed not set, then set_context_ppgtt_from_shadow() will report error. Pin for context after shadow_mm pinned and shadow pdps settled. v2: Move set_context_ppgtt_from_shadow() after prepare_workload().

A single 32-bit PSR2 training pattern field follows the sixteen element array of PSR table entries in the VBT spec. But, we incorrectly define this PSR2 field for each of the PSR table entries. As a result, the PSR1 training pattern duration for any panel_type != 0 will be parsed incorrectly. Secondly, PSR2 training pattern durations for VBTs with bdb version >= 226 will also be wrong.

On VLV/CHV there is some kind of linkage between the cdclk frequency and the DP link frequency. The spec says: "For DP audio configuration, cdclk frequency shall be set to meet the following requirements: DP Link Frequency(MHz) | Cdclk frequency(MHz) 270 | 320 or higher 162 | 200 or higher" I suspect that would more accurately be expressed as "cdclk >= DP link clock", and in any case we can express it like that in the code because of the limited set of cdclk (200, 266, 320, 400 MHz) and link frequencies (162 and 270 MHz) we support. Without this we can end up in a situation where the cdclk is too low and enabling DP audio will kill the pipe. Happens eg. with 2560x1440 modes where the 266MHz cdclk is sufficient to pump the pixels (241.5 MHz dotclock) but is too low for the DP audio due to the link frequency being 270 MHz. v2: Spell out the cdclk and link frequencies we actually support Cc: stable@vger.kernel.org Tested-by:

set_page_dirty says: For pages with a mapping this should be done under the page lock for the benefit of asynchronous memory errors who prefer a consistent dirty state. This rule can be broken in some special cases, but should be better not to. Under those rules, it is only safe for us to use the plain set_page_dirty calls for shmemfs/anonymous memory. Userptr may be used with real mappings and so needs to use the locked version (set_page_dirty_lock).

When SAGV is forced to disabled/min/med/max in the BIOS pcode will only hand us a single QGV point instead of the normal three. Fix the code to deal with that instead declaring the bandwidth limit to be 0 MB/s (and thus preventing any planes from being enabled). Also shrink the max_bw sturct a bit while at it, and change the deratedbw type to unsigned since the code returns the bw as an unsigned int. Since we now keep track of how many qgv points we got from pcode we can drop the earlier check added for the "pcode doesn't support the memory subsystem query" case.

Gen2 doesn't have a frame counter and apparently we no longer provide a fake .get_vblank_counter() hook for it. That means all tracepoints calling that hook will oops. Update the tracepoints to use intel_crtc_get_vblank_counter() which will gracefully fall back to using the software counter. This is actually a better approach since we now get (hopefully accurate) frame numbers in the traces. This also gets rid of the raw driver->get_vblank_counter() calls, which we need to do in order to switch to the per-crtc vblank vfuncs. v2: Deal with new tracepoints v3: Use a distinct variable name for the internal crtc iterator (Chris) Cc: Shawn Guo <shawn.guo@linaro.org> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Fixes: 967dd484 ("drm: remove drm_vblank_no_hw_counter assignment from driver code") Signed-off-by:

Pull ARM SoC fixes from Olof Johansson: "Here's the first batch of fixes for this release cycle. Main diffstat here is the re-deletion of netx. I messed up and most likely didn't remove the files from the index when I test-merged this and saw conflicts, and from there on out 'git rerere' remembered the mistake and I missed checking it. Here it's done again as expected.

Pull x86 fixes from Thomas Gleixner: "A set of x86 fixes and functional updates: - Prevent stale huge I/O TLB mappings on 32bit. A long standing bug which got exposed by KPTI support for 32bit - Prevent bogus access_ok() warnings in arch_stack_walk_user() - Add display quirks for Lenovo devices which have height and width swapped - Add the missing CR2 fixup for 32 bit async pagefaults. Fallout of the CR2 bug fix series. - Unbreak handling of force enabled HPET by moving the 'is HPET counting' check back to the original place. - A more accurate check for running on a hypervisor platform in the MDS mitigation code. Not perfect, but more accurate than the previous one. - Update a stale and confusing comment vs. IRQ stacks" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/speculation/mds: Apply more accurate check on hypervisor platform x86/hpet: Undo the early counter is counting check x86/entry/32: Pass cr2 to do_async_page_fault() x86/irq/64: Update stale comment x86/sysfb_efi: Add quirks for some devices with swapped width and height x86/stacktrace: Prevent access_ok() warnings in arch_stack_walk_user() mm/vmalloc: Sync unmappings in __purge_vmap_area_lazy() x86/mm: Sync also unmappings in vmalloc_sync_all() x86/mm: Check for pfn instead of page in vmalloc_sync_one() -
