The way the tile mode array index was calculated only makes sense for the CIK specific macrotile mode array.

2014-04-25drm/i915: Don't WARN nor handle unexpected hpd interrupts on gmch platformsDaniel Vetter
The status bits are unconditionally set, the control bits only enable the actual interrupt generation. Which means if we get some random other interrupts we'll bogusly complain about them. So restrict the WARN to platforms with a sane hotplug interrupt handling scheme. And even more important also don't attempt to process the hpd bit since we've detected a storm already. Instead just clear the bit silently.

2014-04-25drm/msm/mdp4: cure for the cursor blues (v2)Rob Clark
The hw cursor is relatively adept at triggering underflows, which manifest as a "blue flash" (since blue is configured as the underflow color). Juggle a few things around to tighten up the timing for setting cursor registers in DONE irq. And most importantly, don't ever disable the hw cursor. Instead flip it to a blank/empty cursor. This seems far more reliable, as even simply clearing the cursor-enable bit (with no other updates in previous/ following frames) can in some cases cause underflow. v1: original v2: add missing locking spotted by Micah Cc: Micah Richert <richert@braincorporation.com> Signed-off-by: Rob Clark <robdclark@gmail.com>
2014-04-25drm/msm: default to XR24 rather than AR24Rob Clark

In Matt Ropers primary plane series a set of prep patches like commit af2b653bfb4ef40931b4d101ca842ce0c5da57ef Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Apr 1 15:22:32 2014 -0700 drm/i915: Restrict plane loops to only operate on overlay planes (v2) ensured that all exisiting users of the mode_config->plane_list wouldn't change behaviour. Unfortunately tegra seems to have fallen through the cracks. Fix it. This regression was introduced in commit e13161af80c185ecd8dc4641d0f5df58f9e3e0af Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Apr 1 15:22:38 2014 -0700 drm: Add drm_crtc_init_with_planes() (v2) The result was that we've unref'ed the fb for the primary plane twice, leading to a use-after free bug. This is because the drm core will already set crtc->primary->fb to NULL and do the unref for us, and the crtc disable hook is called by the drm crtc helpers for exactly this case. Aside: Now that the fbdev helpers clean up planes there's no longer a need to do this in drivers. So this could probably be nuked entirely in linux-next.

2014-04-23drm/i915: get power domain in case the BIOS enabled eDP VDDPaulo Zanoni
If I unplug the eDP monitor, the BIOS of my machine will enable the VDD bit, then when the driver loads it will think VDD is enabled. It will detect that the eDP is not enabled and return false from intel_edp_init_connector. This will trigger a call to edp_panel_vdd_off_sync(), which trigger a WARN saying that the refcount of the power domain is less than zero. The problem happens because the driver gets a refcount whenever it enables the VDD bit, and puts the refcount whenever it disables the VDD bit. But on this case, the BIOS enabled VDD, so all we do is to call put() without calling get() first, so the code added is there to make sure we always have the get() in case the BIOS enabled the bit.

2014-04-23drm/i915: Don't check gmch state on inherited configsDaniel Vetter
... our current modeset code isn't good enough yet to handle this. The scenario is: 1. BIOS sets up a cloned config with lvds+external screen on the same pipe, e.g. pipe B. 2. We read out that state for pipe B and assign the gmch_pfit state to it. 3. The initial modeset switches the lvds to pipe A but due to lack of atomic modeset we don't recompute the config of pipe B. -> both pipes now claim (in the sw pipe config structure) to use the gmch_pfit, which just won't work.

In commit commit 6375b768a9850b6154478993e5fb566fa4614a9c Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Mon Mar 3 11:33:36 2014 +0200 drm/i915: Reject >165MHz modes w/ DVI monitors the driver started to filter out display modes which exceed the single-link DVI 165Mz dotclock limits when the monitor doesn't report itself as being HDMI compliant. The intent was to filter out all EDID derived modes that require dual-link DVI to operate since we don't support dual-link. However the patch went a bit too far and also causes the driver to reject such modes even when specified by the user. Normally we don't check the sink limitations when setting a mode from the user. This allows the user to specify any mode whether the sink reports to support it or not. This can be useful since often the sinks support more modes than they report in the EDID. So relax the checks a bit, and apply the single-link DVI dotclock limit only when filtering the mode list, and ignore the limit when setting a user specified mode.

git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 fixes from Ted Ts'o: "These are regression and bug fixes for ext4. We had a number of new features in ext4 during this merge window (ZERO_RANGE and COLLAPSE_RANGE fallocate modes, renameat, etc.) so there were many more regression and bug fixes this time around. It didn't help that xfstests hadn't been fully updated to fully stress test COLLAPSE_RANGE until after -rc1" * tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (31 commits) ext4: disable COLLAPSE_RANGE for bigalloc ext4: fix COLLAPSE_RANGE failure with 1KB block size ext4: use EINVAL if not a regular file in ext4_collapse_range() ext4: enforce we are operating on a regular file in ext4_zero_range() ext4: fix extent merging in ext4_ext_shift_path_extents() ext4: discard preallocations after removing space ext4: no need to truncate pagecache twice in collapse range ext4: fix removing status extents in ext4_collapse_range() ext4: use filemap_write_and_wait_range() correctly in collapse range ext4: use truncate_pagecache() in collapse range ext4: remove temporary shim used to merge COLLAPSE_RANGE and ZERO_RANGE ext4: fix ext4_count_free_clusters() with EXT4FS_DEBUG and bigalloc enabled ext4: always check ext4_ext_find_extent result ext4: fix error handling in ext4_ext_shift_extents ext4: silence sparse check warning for function ext4_trim_extent ext4: COLLAPSE_RANGE only works on extent-based files ext4: fix byte order problems introduced by the COLLAPSE_RANGE patches ext4: use i_size_read in ext4_unaligned_aio() fs: disallow all fallocate operation on active swapfile fs: move falloc collapse range check into the filesystem methods ...
2014-04-20um: Memory corruption on startupAnton Ivanov
The reverse case of this race (you must msync before read) is well known. This is the not so common one. It can be triggered only on systems which do a lot of task switching and only at UML startup. If you are starting 200+ UMLs ~ 0.5% will always die without this fix. Signed-off-by: Anton Ivanov <antivano@cisco.com> [rw: minor whitespace fixes] Signed-off-by: Richard Weinberger <richard@nod.at>
2014-04-20um: Missing pipe handlingAnton Ivanov
UML does not handle sigpipe. As a result when running it under expect or redirecting the IO from the console to an external program it will crash if the program stops or exits. Signed-off-by: Anton Ivanov <antivano@cisco.com> Signed-off-by: Richard Weinberger <richard@nod.at>
