2016-07-29drm/radeon: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar
alloc_workqueue replaces deprecated create_singlethread_workqueue(). Each hardware CRTC has a single flip work queue. When a radeon_flip_work_func item is queued, it needs to be executed ASAP because even a slight delay may cause the flip to be delayed by one refresh cycle. Hence, a dedicated workqueue with WQ_HIGHPRI set, has been used here since a delay can cause the outcome to miss the refresh cycle. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary here.

2016-07-29drm/amdgpu: Disable RPM helpers while reprobing connectors on resumeLyude
Just about all of amdgpu's connector probing functions try to acquire runtime PM refs. If we try to do this in the context of amdgpu_resume_kms by calling drm_helper_hpd_irq_event(), we end up deadlocking the system. Since we're guaranteed to be holding the spinlock for RPM in amdgpu_resume_kms, and we already know the GPU is in working order, we need to prevent the RPM helpers from trying to run during the initial connector reprobe on resume. There's a couple of solutions I've explored for fixing this, but this one by far seems to be the simplest and most reliable (plus I'm pretty sure that's what disable_depth is there for anyway). Reproduction recipe: - Get any laptop dual GPUs using PRIME - Make sure runtime PM is enabled for amdgpu - Boot the machine - If the machine managed to boot without hanging, switch out of X to another VT. This should definitely cause X to hang infinitely. Changes since v1: - add appropriate #ifdef checks for CONFIG_PM. This is not very useful, but it appears some kernel test suites test compiling amdgpu with CONFIG_PM disabled, which results in this patch breaking the builds if we don't include this #ifdef Cc: stable@vger.kernel.org Cc: Alex Deucher <alexdeucher@gmail.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Lyude <cpaul@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2016-07-27Add braces to avoid "ambiguous ‘else’" compiler warningsLinus Torvalds
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.

2016-07-26drm/sti: use new Reset APILee Jones
Since 0b52297f228 ("reset: Add support for shared reset controls") the new Reset API now demands consumers choose either an *_exclusive or a *_shared line when requesting reset lines. This issue was found when running a kernel containing the aforementioned patch which includes an informitive WARN(). It implies that one or more used reset lines are in fact shared. This is why we're using the *_shared variant.
