Pull vfs updates from Al Viro: "Assorted cleanups and fixes. Probably the most interesting part long-term is ->d_init() - that will have a bunch of followups in (at least) ceph and lustre, but we'll need to sort the barrier-related rules before it can get used for really non-trivial stuff.

2016-07-27Add braces to avoid "ambiguous ‘else’" compiler warningsLinus Torvalds1-1/+2
Some of our "for_each_xyz()" macro constructs make gcc unhappy about lack of braces around if-statements inside or outside the loop, because the loop construct itself has a "if-then-else" statement inside of it. The resulting warnings look something like this: drivers/gpu/drm/i915/i915_debugfs.c: In function ‘i915_dump_lrc’: drivers/gpu/drm/i915/i915_debugfs.c:2103:6: warning: suggest explicit braces to avoid ambiguous ‘else’ [-Wparentheses] if (ctx != dev_priv->kernel_context) ^ even if the code itself is fine. Since the warning is fairly easy to avoid by adding a braces around the if-statement near the for_each_xyz() construct, do so, rather than disabling the otherwise potentially useful warning. (The if-then-else statements used in the "for_each_xyz()" constructs are designed to be inherently safe even with no braces, but in this case it's quite understandable that gcc isn't really able to tell that). This finally leaves the standard "allmodconfig" build with just a handful of remaining warnings, so new and valid warnings hopefully will stand out.

2016-07-18drm/i915: Treat eDP as always connected, againVille Syrjälä1-1/+1
eDP should be treated as connected even if doesn't have an EDID. In that case we'll use the timings from the VBT. That used to be the case until commit f21a21983ef1 ("drm/i915: Splitting intel_dp_detect") broke things by considering even eDP disconnected if we fail to get an EDID for it. Fix things up again by treating eDP as always connected.

Some Kabylake SKUs are going to use Kabypoint PCH. It is mainly for Halo and DT ones. >From our specs it doesn't seem that KBP brings any change on the display south engine. So let's consider this as a continuation of SunrisePoint, i.e., SPT+. Since it is easy to get confused by a letter change: KBL = Kabylake - CPU/GPU codename. KBP = Kabypoint - PCH codename.

Past evidence with system hangs and hsds tie WaForceEnableNonCoherent and WaDisableHDCInvalidation to WaForceContextSaveRestoreNonCoherent. Documentation states that WaForceContextSaveRestoreNonCoherent would not be needed on skl past E0 but evidence proved otherwise. See commit <510650e8b2ab> ("drm/i915/skl: Fix spurious gpu hang with gt3/gt4 revs").

I've also realized that a pile of hang fixes for kbl landed in next, and no one thought of backporting it to 4.7 - kbl has lost prelim_hw_support tagging in 4.7-rc1 already. Mika is prepping a topic branch for those, will send you a separate pull request since it's quite a bit (but should be all well restricted to kbl code, so similar to polaris in amdgpu). * tag 'drm-intel-fixes-2016-07-14' of git://anongit.freedesktop.org/drm-intel: drm/i915: Ignore panel type from OpRegion on SKL drm/i915: Update ifdeffery for mutex->owner

Dell XPS 13 9350 apparently doesn't like it when we use the panel type from OpRegion. The OpRegion panel type (0) tells us to use use low vswing for eDP, whereas the VBT panel type (2) tells us to use normal vswing. The problem is that low vswing results in some display flickers. Since no one seems to know how this stuff is supposed to be handled, let's just ignore the OpRegion panel type on SKL for now. v2: Print the panel type correctly in the debug output Reported-by: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: drm-intel-fixes@lists.freedesktop.org References: https://lists.freedesktop.org/archives/intel-gfx/2016-June/098826.html Fixes: a05628195a0d ("drm/i915: Get panel_type from OpRegion panel details") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1468324837-29237-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Tested-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> (cherry picked from commit bb10d4ec3be4b069bfb61c60ca4f708f58f440f1) [danvet: Fix up cherry-pick conflict with an s/dev_priv/dev/.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
