drm/amdgpu: disable CRTCs before teardown

2016-09-27T16:22:21Z

Some code called by drm_crtc_force_disable_all() wants to wait for all fences, so only do fence teardown after CRTCs are disabled. Fixes: 84b89bdcedf8 ("drm/amdgpu: Turn off CRTCs on driver unload") Cc: stable@vger.kernel.org # v4.8+ Signed-off-by: Grazvydas Ignotas Signed-off-by: Alex Deucher

drm/amdgpu: Disable RPM helpers while reprobing connectors on resume

2016-07-29T18:36:44Z

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 Reviewed-by: Alex Deucher Signed-off-by: Lyude Signed-off-by: Alex Deucher
