2017-08-14drm/i915: Avoid the gpu reset vs. modeset deadlockDaniel Vetter
... using the biggest hammer we have. This is essentially a weaponized version of the timeout-based wedging Chris added in commit 36703e79a982c8ce5a8e43833291f2719e92d0d1 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Jun 22 11:56:25 2017 +0100 drm/i915: Break modeset deadlocks on reset Because defense-in-depth is good it's good to still have both. Also note that with the locking change we can now restrict this a lot (old gpus and special testing only), so this doesn't kill the TDR benefits on at least anything remotely modern. And futuremore with a few tricks it should be possible to make a much more educated guess about whether an atomic commit is stuck waiting on the gpu (atomic_t counting the pending i915_sw_fence used by the atomic modeset code should do it), so we can improve this. But for now just start with something that is guaranteed to recover faster, for much better CI througput. This defacto reverts TDR on these platforms, but there's not really a single commit to specify as the sole offender. v2: Add a debug message to explain what's going on. We can't DRM_ERROR because that spams CI. And the timeout based fallback still prints a DRM_ERROR, in case something goes wrong. v3: Fix comment layout (Michel) Fixes: 4680816be336 ("drm/i915: Wait first for submission, before waiting for request completion") Fixes: 221fe7994554 ("drm/i915: Perform a direct reset of the GPU from the waiter") Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> (v2) Cc: Michel Thierry <michel.thierry@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> (v2) Reviewed-by: Michel Thierry <michel.thierry@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170808080828.23650-1-daniel.vetter@ffwll.ch (cherry picked from commit 97154ec242c14f646a3ab3b4da8f838d197f300d) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2017-08-14drm/i915: Suppress switch_mm emission between the same aliasing_ppgttChris Wilson
When switching between contexts using the aliasing_ppgtt, the VM is shared. We don't need to reload the PD registers unless they are dirty. Martin Peres reported an issue that looks like corruption between Haswell context switches, bisecting to commit f9326be5f1d3 ("drm/i915: Rearrange switch_context to load the aliasing ppgtt on first use"). Switching between the same mm (the aliasing_ppgtt is used for all contexts in this case) should be a nop, but appears to trigger some side-effects in the context switch. However, as we know the switch is redundant in this case, we can skip it and continue to ignore the issue until somebody feels strong enough to investigate full-ppgtt on gen7 again! Except.. Martin was using full-ppgtt which is not supported as it doesn't work correctly yet. So whilst the bisect did yield valuable information about the failures, the fix should not have any user impact under default settings, with the exception of a slightly lower throughput on xcs as the VM would always be reloaded. v2: Also remember to set the legacy_active_context following the switch on xcs (commit e8a9c58fcd9a ("drm/i915: Unify active context tracking between legacy/execlists/guc")) Fixes: f9326be5f1d3 ("drm/i915: Rearrange switch_context to load the aliasing ppgtt on first use") Fixes: e8a9c58fcd9a ("drm/i915: Unify active context tracking between legacy/execlists/guc") Reported-by: Martin Peres <martin.peres@linux.intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Martin Peres <martin.peres@linux.intel.com> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170812152724.6883-1-chris@chris-wilson.co.uk (cherry picked from commit 12124bea5b82dc1e917304aed703c27292270051) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2017-08-14drm/i915: Perform an invalidate prior to executing golden renderstateChris Wilson
As we may have just bound the renderstate into the GGTT for execution, we need to ensure that the GTT TLB are also flushed. On snb-gt2, this would cause a random GPU hang at the start of a new context (e.g. boot) and on snb-gt1, it was causing the renderstate batch to take ~10s. It was the GPU hang that revealed the truth, as the CS gleefully executed beyond the end of the golden renderstate batch, a good indicator for a GTT TLB miss.

2017-08-14brcmfmac: feature check for multi-scheduled scan fails on bcm4343x devicesArend Van Spriel
The firmware feature check introduced for multi-scheduled scan turned out to be failing for bcm4343{0,1,8} devices resulting in a firmware crash. The reason for this crash has not yet been root cause so this patch avoids the feature check for those device as a short-term fix.

2017-08-14arm64: allwinner: h5: fix pinctrl IRQsIcenowy Zheng
The pin controller of H5 has three IRQs at the chip's GIC, which represents three banks of pinctrl IRQs. However, the device tree used to miss the third IRQ of the pin controller, which makes the PG bank IRQ not usable. Add the missing IRQ to the pinctrl node.
