2012-11-29drm/exynos: fix lockdep for event_lock wrt. vbl_time_lockImre Deak
Currently the exynos driver calls drm_vblank_off() with the event_lock held, while drm_vblank_off() will lock vbl_time and vblank_time_lock. This lock dependency chain conflicts with the one in drm_handle_vblank() where we first lock vblank_time_lock and then the event_lock. Fix this by removing the above drm_vblank_off() calls which are in fact never executed: drm_dev->vblank_disable_allowed is only ever non-zero during driver init, until it's set in {fimd,vidi}_subdrv_probe. Both the driver init and open code is protected by drm_global_mutex, so the earliest page flip ioctl can happen only after vblank_disable_allowed is set to 1. Thus {fimd,vidi}_finish_pageflip - with pending flip events - will always get called with vblank_disable_allowed being 1.

2012-11-29drm/exynos: call drm_vblank_put for each queued flip eventImre Deak
It's guaranteed that for each event on pageflip_event_list we have called drm_vblank_get() - see exynos_drm_crtc_page_flip() - so checking for this is redundant. Also we need to call drm_vblank_put() for each event on the list, not only once, otherwise we'd leak vblank references if there are multiple events on the list.

2012-11-29drm/exynos: fix overlay updating issueInki Dae
Chagelog v2: Move encoder's dpms updating into exynos_drm_encoder_commit function because when crtc's dpms is updated, encoder's dpms is updated also. This would induce the issue that encoder isn't disabled after crtc is disabled. Changelog v1: This patch fixes a issue that overlay data aren't applied to real hardware when dpms off goes to on after setcrtc was requested like below, dpms off -> setcrtc -> dpms off -> dpms on For this, it makes encoder's dpms to be updated when setcrtc is requested.

2012-11-29Merge branch 'for-airlied' of git://people.freedesktop.org/~danvet/drm-intel ↵Dave Airlie
into drm-next Daniel writes: Besides the big item of lifting the "preliminary hw support" tag from the Haswell code, just small bits&pieces all over: - Leftover Haswell patches and some fixes from Paulo - LyncPoint PCH support (for hsw) - OOM handling improvements from Chris Wilson - connector property and send_vblank_event refactorings from Rob Clark - random pile of small fixes Note that the send_vblank refactorings will cause some locking WARNs to show up. Imre has fixed that up, but since all the driver changes outside of the drm core have been for exonys, those four patches are merged through the exonys-next tree. Meh, I've forgotten to cherry-pick an important fix from Ben for a regression in the 3.8 gen6+ gtt code. New pull request below.

2012-11-29drm/i915: Fix pte updates in ggtt clear rangeBen Widawsky
This bug was introduced by me: commit e76e9aebcdbfebae8f4cd147e3c0f800d36e97f3 Author: Ben Widawsky <ben@bwidawsk.net> Date: Sun Nov 4 09:21:27 2012 -0800 drm/i915: Stop using AGP layer for GEN6+ The existing code uses memset_io which follows memset semantics in only guaranteeing a write of individual bytes. Since a PTE entry is 4 bytes, this can only be correct if the scratch page address is 0. This caused unsightly errors when we clear the range at load time, though I'm not really sure what the heck is referencing that memory anyway. I caught this is because I believe we have some other bug where the display is doing reads of memory we feel should be cleared (or we are relying on scratch pages to be a specific value).

2012-11-29drm/nve0: allow specification of channel engine type in abi16 callBen Skeggs
Previously, if either vram/gart handles were specified as ~0, the ioctl call would fail. In order to hack engine selection into the ioctl for kepler, we now define (fb_ctxdma_handle == ~0) to mean "engine mask is in tt_ctxdma_handle". This approach also allows new userspace to detect lack of support for non-PGRAPH channels on older kernels. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
