Weine's investigation on benchmarking the suspend/resume process pointed out a lot of the time in suspend/resume is being spent reprobing. While the reprobing process is a lengthy one for good reason, we don't need to hold up the entire suspend/resume process while we wait for it to finish. Luckily as it turns out, we already trigger a full connector reprobe in i915_hpd_poll_init_work(), so we can just ditch reprobing in i915_drm_resume() entirely. This won't lead to less time spent resuming just yet since now the bottleneck will be waiting for the mode_config lock in drm_kms_helper_poll_enable(), since that will be held as long as i915_hpd_poll_init_work() is reprobing all of the connectors. But we'll address that in the next patch. Signed-off-by:

According to BSpec, cdclk for BDW has to be not less than 432 MHz with DP audio enabled, port width x4, and link rate HBR2 (5.4 GHz). With cdclk less than 432 MHz, enabling audio leads to pipe FIFO underruns and displays cycling on/off. Let's apply this work around to GEN9 platforms too, as it fixes the same issue. v2: Move drm_device to drm_i915_private conversion Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97907 Cc: stable@vger.kernel.org Cc: Libin Yang <libin.yang@linux.intel.com> Signed-off-by:

With cdclk less than 432 MHz, enabling audio leads to pipe FIFO underruns and displays cycling on/off. From BSpec: "Display» BDW-SKL» dpr» [Register] DP_TP_CTL [BDW+,EXCLUDE(CHV)] Workaround : Do not use DisplayPort with CDCLK less than 432 MHz, audio enabled, port width x4, and link rate HBR2 (5.4 GHz), or else there may be audio corruption or screen corruption." Since, some DP configurations (e.g., MST) use port width x4 and HBR2 link rate, let's increase the cdclk to >= 432 MHz to enable audio for those cases. v4: Changed commit message v3: Combine BDW pixel rate adjustments into a function (Jani) v2: Restrict fix to BDW Retain the set cdclk across modesets (Ville) Cc: stable@vger.kernel.org Signed-off-by:Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

commit bc0629a7 ("drm/i915: Track pages pinned due to swizzling quirk") fixed one problem, but revealed a whole lot more. The root cause of the pin count mismatch for the swizzle quirk (for L-shaped memory on gen3/4) was that we were incrementing the pages_pin_count upon getting the backing pages but then overwriting the pages_pin_count to set it to 1 afterwards. With a little bit of adjustment to satisfy the GEM_BUG_ON sanitychecks, the fix is to replace the explicit atomic_set with an atomic_inc. v2: Consistently use atomics (not mix atomics and helpers) within the lowlevel get_pages routines. This makes the atomic operations much clearer. Fixes: 1233e2db ("drm/i915: Move object backing storage manipulation") Signed-off-by:

When supplying a view to vma_compare() it is required that the supplied i915_address_space is the global GTT. I tested the VMA instead (which is the current position in the rbtree and maybe from any address space). Reported-by:

Use i915_gem_object_pin_map() for the guc client's lifetime to replace the peristent kmap + frequent kmap_atomic with a permanent vmapping. This avoids taking the obj->mm.lock mutex whilst inside irq context later.

Commit 1bec9b0b ("drm/i915/shrinker: Only shmemfs objects are backed by swap") stopped considering the userptr objects in shrinker callbacks. Restore that so idle userptr objects can be discarded in order to free up memory. One change further to what was introduced in 1bec9b0b is to start considering userptr objects in oom but that should also be a correct thing to do. v2: Introduce I915_GEM_OBJECT_IS_SHRINKABLE.
