2018-07-03drm: Change deadlock-avoidance algorithm for the modeset locks.Thomas Hellstrom1-1/+1

2018-07-03locking: Implement an algorithm choice for Wound-Wait mutexesThomas Hellstrom2-2/+2
The current Wound-Wait mutex algorithm is actually not Wound-Wait but Wait-Die. Implement also Wound-Wait as a per-ww-class choice. Wound-Wait is, contrary to Wait-Die a preemptive algorithm and is known to generate fewer backoffs. Testing reveals that this is true if the number of simultaneous contending transactions is small. As the number of simultaneous contending threads increases, Wait-Wound becomes inferior to Wait-Die in terms of elapsed time. Possibly due to the larger number of held locks of sleeping transactions. Update documentation and callers. Timings using git://people.freedesktop.org/~thomash/ww_mutex_test tag patch-18-06-15 Each thread runs 100000 batches of lock / unlock 800 ww mutexes randomly chosen out of 100000.

2018-07-03drm: add missing ctx argument to plane transitional helpersRussell King10-11/+15
In commits: 34a2ab5e0689 ("drm: Add acquire ctx parameter to ->update_plane") 1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable") a pointer to a drm_modeset_acquire_ctx structure was added as an argument to the method prototypes. The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument. A number of buggy users were added for drm_plane_helper_disable() which need to be fixed up for this change, which we do by passing a NULL ctx argument.

2018-07-02dma-fence: Allow wait_any_timeout for all fencesDaniel Vetter1-5/+0
When this was introduced in commit a519435a96597d8cd96123246fea4ae5a6c90b02 Author: Christian König <[email protected]> Date: Tue Oct 20 16:34:16 2015 +0200 dma-buf/fence: add fence_wait_any_timeout function v2 there was a restriction added that this only works if the dma-fence uses the dma_fence_default_wait hook. Which works for amdgpu, which is the only caller. Well, until you share some buffers with e.g. i915, then you get an -EINVAL. But there's really no reason for this, because all drivers must support callbacks. The special ->wait hook is only as an optimization; if the driver needs to create a worker thread for an active callback, then it can avoid to do that if it knows that there's a process context available already. So ->wait is just an optimization, just using the logic in dma_fence_default_wait() should work for all drivers. Let's remove this restriction.

2018-07-02dma-fence: Make ->enable_signaling optionalDaniel Vetter1-4/+5
Many drivers have a trivial implementation for ->enable_signaling. Let's make it optional by assuming that signalling is already available when the callback isn't present. v2: Don't do the trick to set the ENABLE_SIGNAL_BIT unconditionally, it results in an expensive spinlock take for everyone. Instead just check if the callback is present. Suggested by Maarten. Also move misplaced kerneldoc hunk to the right patch.

2018-07-01drm/pl111: Support Nomadik LCDC variantLinus Walleij6-13/+145
The Nomadik has a variant of the PL110 known as "Color LCD Controller" LCDC. This variant has the same bit ordering as the DRM subsystem (in difference from the other variants) and adds a few bits for the control of 5551, 565 etc in the control register. Notably it also adds a packed RGB888 24BPP mode. We add support by detecting this variant and also adding a small plug-in that will mux the LCDC out if the ASIC happens to be muxed to the other graphics controller (they are mutually exclusive).

Pull block fixes from Jens Axboe: "Small set of fixes for this series. Mostly just minor fixes, the only oddball in here is the sg change. The sg change came out of the stall fix for NVMe, where we added a mempool and limited us to a single page allocation. CONFIG_SG_DEBUG sort-of ruins that, since we'd need to account for that. That's actually a generic problem, since lots of drivers need to allocate SG lists.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix dm core to use more efficient bio_split() instead of bio_clone_bioset(). Also fixes splitting bio that has integrity payload. - Three fixes related to properly validating DAX capabilities of a stacked DM device that will advertise DAX support. - Update DM writecache target to use 2-factor allocator arguments. Kees says this is the last related change for 4.18. - Fix DM zoned target to use GFP_NOIO to avoid triggering reclaim during IO submission (caught by lockdep). - Fix DM thinp to gracefully recover from running out of data space while a previous async discard completes (whereby freeing space). - Fix DM thinp's metadata transaction commit to avoid needless work. * tag 'for-4.18/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: prevent DAX mounts if not supported dax: check for QUEUE_FLAG_DAX in bdev_dax_supported() pmem: only set QUEUE_FLAG_DAX for fsdax mode dm thin: handle running out of data space vs concurrent discard dm raid: don't use 'const' in function return dm zoned: avoid triggering reclaim from inside dmz_map() dm writecache: use 2-factor allocator arguments dm thin metadata: remove needless work from __commit_transaction dm: use bio_split() when splitting out the already processed bio

2018-06-29Revert "i2c: algo-bit: init the bus to a known state"Wolfram Sang1-5/+0
This reverts commit 3e5f06bed72fe72166a6778f630241a893f67799. As per bugzilla #200045, this caused a regression. I don't really see a way to fix it without having the hardware. So, revert the patch and I will fix the issue I was seeing originally in the i2c-gpio driver itself. I couldn't find new users of this algorithm since, so there should be no one depending on the new behaviour.
