We don't do CPU access to GPU contexts so making the GPU access snoop the CPU caches seems silly, and potentially expensive. v2: Use !IS_VALLEYVIEW instead of HAS_LLC as this is really about what the PTEs can represent.

Loading cursors to the LCD controller's SRAM can be corrupted when the configured pixel clock is relatively slow. This seems to be caused when we write back-to-back to the SRAM registers. There doesn't appear to be any status register we can read to check when an access has completed. Inserting a dummy read between the writes appears to fix the problem.

During resume the intel hda audio driver depends on the i915 driver reinitializing the audio power domain. Since the order of calling the i915 resume handler wrt. that of the audio driver is not guaranteed, move the power domain reinitialization step to the resume_early handler. This is guaranteed to run before the resume handler of any other driver. The power domain initialization in turn requires us to enable the i915 pci device first, so move that part earlier too. Accordingly disabling of the i915 pci device should happen after the audio suspend handler ran. So move the disabling later from the i915 resume handler to the resume_late handler. v2: - move intel_uncore_sanitize/early_sanitize earlier too, so they don't get reordered wrt. intel_power_domains_init_hw() Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=76152Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Takashi Iwai <tiwai@suse.de> Cc: stable@vger.kernel.org [danvet: Add cc: stable and loud comments that this is just a hack.] [danvet: Fix "Should it be static?" sparse warning reported by Wu Fengguang's kbuilder.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
