2019-08-01drm/i915: Lift intel_engines_resume() to callersChris Wilson
Since the reset path wants to recover the engines itself, it only wants to reinitialise the hardware using i915_gem_init_hw(). Pull the call to intel_engines_resume() to the module init/resume path so we can avoid it during reset.

2019-07-31drm/msm: Use the correct dma_sync calls in msm_gemRob Clark
[subject was: drm/msm: shake fist angrily at dma-mapping] So, using dma_sync_* for our cache needs works out w/ dma iommu ops, but it falls appart with dma direct ops. The problem is that, depending on display generation, we can have either set of dma ops (mdp4 and dpu have iommu wired to mdss node, which maps to toplevel drm device, but mdp5 has iommu wired up to the mdp sub-node within mdss).

2019-07-31drm/amdgpu: fix a potential information leaking bugWang Xiayang
Coccinelle reports a path that the array "data" is never initialized. The path skips the checks in the conditional branches when either of callback functions, read_wave_vgprs and read_wave_sgprs, is not registered. Later, the uninitialized "data" array is read in the while-loop below and passed to put_user(). Fix the path by allocating the array with kcalloc(). The patch is simplier than adding a fall-back branch that explicitly calls memset(data, 0, ...). Also it does not need the multiplication 1024*sizeof(*data) as the size parameter for memset() though there is no risk of integer overflow.

2019-07-30drm/i915/gvt: Adding ppgtt to GVT GEM context after shadow pdps settled.Colin Xu
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().

2019-07-29drm/i915: Make sure cdclk is high enough for DP audio on VLV/CHVVille Syrjälä
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: Stefan Gottwald <gottwald@igel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=111149 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190717114536.22937-1-ville.syrjala@linux.intel.com Acked-by: Chris Wilson <chris@chris-wilson.co.uk> (cherry picked from commit bffb31f73b29a60ef693842d8744950c2819851d) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2019-07-29drm/i915: Lock the engine while dumping the active requestChris Wilson
We cannot let the request be retired and freed while we are trying to dump it during error capture. It is not sufficient just to grab a reference to the request, as during retirement we may free the ring which we are also dumping. So take the engine lock to prevent retiring and freeing of the request.

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).

2019-07-29drm/i915: Deal with machines that expose less than three QGV pointsVille Syrjälä
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.
