2016-05-10drm/i915: Re-enable GGTT earlier during resume on pre-gen6 platformsVille Syrjälä5-3/+20
Move the intel_enable_gtt() call to happen before we touch the GTT during resume. Right now it's done way too late. Before commit ebb7c78d358b ("agp/intel-gtt: Only register fake agp driver for gen1") it was actually done earlier on account of also getting called from the resume hook of the fake agp driver. With the fake agp driver no longer getting registered we must move the call up. The symptoms I've seen on my 830 machine include lowmem corruption, other kinds of memory corruption, and straight up hung machine during or just after resume. Not really sure what causes the memory corruption, but so far I've not seen any with this fix. I think we shouldn't really need to call this during init, but we have been doing that so I've decided to keep the call. However moving that call earlier could be prudent as well. Doing it right after the intel-gtt probe seems appropriate. Also tested this on 946gz,elk,ilk and all seemed quite happy with this change. v2: Reorder init_hw vs. enable_hw functions (Chris) Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: drm-intel-fixes@lists.freedesktop.org Fixes: ebb7c78d358b ("agp/intel-gtt: Only register fake agp driver for gen1") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1462559755-353-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-05-10Merge branch 'drm-etnaviv-next' of git://git.pengutronix.de:/git/lst/linux ↵Dave Airlie5-7/+24
into drm-next not much new stuff this time. A (micro-)optimization to allow the hangcheck timer to be coalesced with other wakeups in the system and a fix to handle mmaping of prime imported and userptr buffers correctly. I don't think we have seen any actual issues going back to this yet, so I figured it's safer to get this in via drm-next rather than smashing it into fixes. * 'drm-etnaviv-next' of git://git.pengutronix.de:/git/lst/linux: drm/etnaviv: fix mmap operations for userptr and dma-buf objects drm/etnaviv: take etnaviv_gem_obj in etnaviv_gem_mmap_obj drm/etnaviv: use deferrable timer for hangcheck handler timer: add setup_deferrable_timer macro

2016-05-09drm/i915: Add a FIXME about crtc !active vs. watermarksVille Syrjälä1-0/+5
When the crtc is enabled but !active, we should still compute the watermarks as if the planes were visible. That would make it more likely that the we can later transition to active without errors. Add a FIXME to remind people that we're doing the wrong thing now. We should perhaps just move the wm computation for each individual plane into the .check_plane hook, and later we'd just combine the results from all active planes.

Use the cdclk we're going to be using when the pipe gets enabled to compute the IPS linetime watermark. The current cdclk frequency is irrelevant at this point since it can still change.
