87e956e9 changed the fault handler to return -ENOSYS, which causes the iommu driver to print out a huge splat. Which wouldn't be quite so bad if nothing ever faulted. But seems like some EXA composite operations generate quite a lot of (seemingly harmless) faults. That is probably a userspace problem, but the huge increase in verbosity from iommu fault dumps makes things kind of unusable. We probably should actually log *some* message (not conditional on drm.debug). But ratelimit it. Signed-off-by: Rob Clark <robdclark@gmail.com>

Make sure these work handlers don't run after we system suspend or unload the driver. Note that we don't cancel the handlers during runtime suspend. That could lead to a lockup, since we take a runtime PM ref from the handlers themselves.

Atm, the HPD IRQ reenable timer can get rearmed right after it's canceled. Also to access the HPD IRQ mask registers we need to wake up the HW. Solve both issues by converting the reenable timer to a delayed work and grabbing a runtime PM reference in the work. By this we can also forgo canceling the timer during runtime suspend, since the only important thing there is that the HW is awake when we write the registers and that's ensured by the RPM ref. So do the cancelation only during driver unload time; this is also a requirement for an upcoming patch where we want to cancel all HPD related works only during system suspend and driver unload time, but not during runtime suspend. Note that there is still a race between the HPD IRQ reenable work and drm_irq_uninstall() during driver unload, where the work can reenable the HPD IRQs disabled by drm_irq_uninstall(). This isn't a problem since the HPD IRQs will still be effectively masked by the first level interrupt mask. v2-3: - unchanged v4: - use proper API for changing the expiration time for an already pending delayed work (Jani) Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> (v2) Cc: stable@vger.kernel.org (3.16+) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

During suspend we turn off the crtcs, but leave the staged config in place so that we can restore the display(s) to their previous state on resume. During resume when we attempt to apply the force pipe A quirk we use the load detect mechanism. That doesn't check whether there was an already staged configuration for the crtc since that's not even possible during normal runtime load detection. But during resume it is possible, and if we just blindly go and overwrite the staged crtc configuration for the load detection we can no longer restore the display to the correct state. Even worse, we don't even clear all the staged connector->encoder->crtc links so we may end up using a cloned setup for the load detection, and after we're done we just clear the links related to the VGA output leaving the links for the other outputs in place. This will eventually result in calling intel_set_mode() with mode==NULL but with valid connector->encoder->crtc links which will result in dereferencing the NULL mode since the code thinks it will have to a modeset. To avoid these problems don't use any crtc with new_enabled==true for load detection.

intel_enable_pipe_a() gets called with all the modeset locks already held (by drm_modeset_lock_all()), so trying to grab the same locks using another drm_modeset_acquire_ctx is going to fail miserably. Move most of the drm_modeset_acquire_ctx handling (init/drop/fini) out from intel_{get,release}_load_detect_pipe() into the callers (intel_{crt,tv}_detect()). Only the actual locking and backoff handling is left in intel_get_load_detect_pipe(). And in intel_enable_pipe_a() we just share the mode_config.acquire_ctx from drm_modeset_lock_all() which is already holding all the relevant locks. It's perfectly legal to lock the same ww_mutex multiple times using the same ww_acquire_ctx. drm_modeset_lock() will convert the returned -EALREADY into 0, so the caller doesn't need to do antyhing special. Fixes a hang on resume on my 830.
