2014-09-24drm: Fixup locking for universal cursor planesDaniel Vetter
Bunch of things amiss: - Updating crtc->cursor_x/y was done without any locking. Spotted by David Herrmann. - Dereferencing crtc->cursor->fb was using the wrong lock, should take the crtc lock. - Grabbing _all_ modeset locks torpedoes the reason why we added fine-grained locks originally: Cursor updates shouldn't stall on background stuff like probing outputs. Best is to just grab the crtc lock around everything and drop all the other locking. The only issue is that we can't switch planes between crtcs with that, so make sure that never happens when someone uses universal plane helpers. This shouldn't be a possible regression ever since legacy ioctls also only grabbed the crtc lock, so switching crtcs was never possible for the underlying plane object. And i915 (the only user of universal cursors thus far) has fixed cursor->crtc links.

2014-09-24drm: Don't update vblank timestamp when the counter didn't changeMario Kleiner
If we already have a timestamp for the current vblank counter, don't update it with a new timestmap. Small errors can creep in between two timestamp queries for the same vblank count, which could be confusing to userspace when it queries the timestamp for the same vblank sequence number twice. This problem gets exposed when the vblank disable timer is not used (or is set to expire quickly) and thus we can get multiple vblank disable<->enable transition during the same frame which would all attempt to update the timestamp with the latest estimate.

The only user I could dig out was i915 back when ums+gem was still a thing. But we've just very much killed that, and even when someone screams about that we should resurrect that with a special hack (wrapping drm_gem_mmap) in i915, not in the core code.

2014-09-23drm/ttm: Clean usage of ttm_io_prot() with TTM_PL_FLAG_CACHEDBenjamin Herrenschmidt
Today, most callers of ttm_io_prot() check TTM_PL_FLAG_CACHED before calling it since on some archs it will unconditionally create non-cached mappings. But not all callers do which is incorrect as far as I can tell.

2014-09-19drm/exynos: switch to universal plane APIAndrzej Hajda
The patch replaces legacy functions drm_plane_init() / drm_crtc_init() with drm_universal_plane_init() and drm_crtc_init_with_planes(). It allows to replace fake primary plane with the real one. Additionally the patch leaves cleanup of crtcs to core, this way planes and crtcs are cleaned in correct order.

2014-09-19drm/exynos: use drm generic mmap interfaceInki Dae
This patch removes DRM_EXYNOS_GEM_MMAP ictrl feature specific to Exynos drm and instead uses drm generic mmap. We had used the interface specific to Exynos drm to do mmap directly, not to use demand paging which maps each page with physical memory at page fault handler. We don't need the specific mmap interface because the drm generic mmap which uses vm offset manager stuff can also do mmap directly. This patch makes a userspace region to be mapped with whole physical memory region allocated by userspace request when mmap system call is requested. Changelog v2: - do not set VM_IO, VM_DONTEXPEND and VM_DONTDUMP. These flags were already set by drm_gem_mmap - do not include <linux/anon_inodes.h>, which isn't needed anymore.
