git://anongit.freedesktop.org/git/drm-intel into drm-next Final pile of features for 4.14 - New ioctl to change NOA configurations, plus prep (Lionel) - CCS (color compression) scanout support, based on the fancy new modifier additions (Ville&Ben) - Document i915 register macro style (Jani) - Many more gen10/cnl patches (Rodrigo, Pualo, ...) - More gpu reset vs. modeset duct-tape to restore the old way. - prep work for cnl: hpd_pin reorg (Rodrigo), support for more power wells (Imre), i2c pin reorg (Anusha) - drm_syncobj support (Jason Ekstrand) - forcewake vs gpu reset fix (Chris) - execbuf speedup for the no-relocs fastpath, anv/vk low-overhead ftw (Chris) - switch to idr/radixtree instead of the resizing ht for execbuf id->vma lookups (Chris) gvt: - MMIO save/restore optimization (Changbin) - Split workload scan vs. dispatch for more parallel exec (Ping) - vGPU full 48bit ppgtt support (Joonas, Tina) - vGPU hw id expose for perf (Zhenyu) Bunch of work all over to make the igt CI runs more complete/stable. Watch https://intel-gfx-ci.01.org/tree/drm-tip/shards-all.html for progress in getting this ready. Next week we're going into production mode (i.e. will send results to intel-gfx) on hsw, more platforms to come. Also, a new maintainer tram, I'm stepping out.

2017-07-31efifb: allow user to disable write combined mapping.Dave Airlie1-0/+6
This patch allows the user to disable write combined mapping of the efifb framebuffer console using an nowc option. A customer noticed major slowdowns while logging to the console with write combining enabled, on other tasks running on the same CPU. (10x or greater slow down on all other cores on the same CPU as is doing the logging). I reproduced this on a machine with dual CPUs. Intel(R) Xeon(R) CPU E5-2609 v3 @ 1.90GHz (6 core) I wrote a test that just mmaps the pci bar and writes to it in a loop, while this was running in the background one a single core with (taskset -c 1), building a kernel up to init/version.o (taskset -c 8) went from 13s to 133s or so. I've yet to explain why this occurs or what is going wrong I haven't managed to find a perf command that in any way gives insight into this. 11,885,070,715 instructions # 1.39 insns per cycle vs 12,082,592,342 instructions # 0.13 insns per cycle is the only thing I've spotted of interest, I've tried at least: dTLB-stores,dTLB-store-misses,L1-dcache-stores,LLC-store,LLC-store-misses,LLC-load-misses,LLC-loads,\mem-loads,mem-stores,iTLB-loads,iTLB-load-misses,cache-references,cache-misses For now it seems at least a good idea to allow a user to disable write combining if they see this until we can figure it out. Note also most users get a real framebuffer driver loaded when kms kicks in, it just happens on these machines the kernel didn't support the gpu specific driver.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - a few DM integrity fixes that improve performance. One that address inefficiencies in the on-disk journal device layout. Another that makes use of the block layer's on-stack plugging when writing the journal. - a dm-bufio fix for the blk_status_t conversion that went in during the merge window. - a few DM raid fixes that address correctness when suspending the device and a validation fix for validation that occurs during device activation. - a couple DM zoned target fixes. Important one being the fix to not use GFP_KERNEL in the IO path due to concerns about deadlock in low-memory conditions (e.g. swap over a DM zoned device, etc). - a DM DAX device fix to make sure dm_dax_flush() is called if the underlying DAX device is operating as a write cache. * tag 'for-4.13/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm, dax: Make sure dm_dax_flush() is called if device supports it dm verity fec: fix GFP flags used with mempool_alloc() dm zoned: use GFP_NOIO in I/O path dm zoned: remove test for impossible REQ_OP_FLUSH conditions dm raid: bump target version dm raid: avoid mddev->suspended access dm raid: fix activation check in validate_raid_redundancy() dm raid: remove WARN_ON() in raid10_md_layout_to_format() dm bufio: fix error code in dm_bufio_write_dirty_buffers() dm integrity: test for corrupted disk format during table load dm integrity: WARN_ON if variables representing journal usage get out of sync dm integrity: use plugging when writing the journal dm integrity: fix inefficient allocation of journal space

Sending patches with SVG files via e-mail has a drawback: line size could be bigger than 998, with is the limit given by RFC 5322[1]. So, we need to enforce a lower limit, in order to allow those patches to be properly reviewed.
