Hi Dave, drm-intel-next-2016-05-22: - cmd-parser support for direct reg->reg loads (Ken Graunke) - better handle DP++ smart dongles (Ville) - bxt guc fw loading support (Nick Hoathe) - remove a bunch of struct typedefs from dpll code (Ander) - tons of small work all over to avoid casting between drm_device and the i915 dev struct (Tvrtko&Chris) - untangle request retiring from other operations, also fixes reset stat corner cases (Chris) - skl atomic watermark support from Matt Roper, yay! - various wm handling bugfixes from Ville - big pile of cdclck rework for bxt/skl (Ville) - CABC (Content Adaptive Brigthness Control) for dsi panels (Jani&Deepak M) - nonblocking atomic commits for plane-only updates (Maarten Lankhorst) - bunch of PSR fixes&improvements - untangle our map/pin/sg_iter code a bit (Dave Gordon) drm-intel-next-2016-05-08: - refactor stolen quirks to share code between early quirks and i915 (Joonas) - refactor gem BO/vma funcstion (Tvrtko&Dave) - backlight over DPCD support (Yetunde Abedisi) - more dsi panel sequence support (Jani) - lots of refactoring around handling iomaps, vma, ring access and related topics culmulating in removing the duplicated request tracking in the execlist code (Chris & Tvrtko) includes a small patch for core iomapping code - hw state readout for bxt dsi (Ramalingam C) - cdclk cleanups (Ville) - dedupe chv pll code a bit (Ander) - enable semaphores on gen8+ for legacy submission, to be able to have a direct comparison against execlist on the same platform (Chris) Not meant to be used for anything else but performance tuning - lvds border bit hw state checker fix (Jani) - rpm vs. shrinker/oom-notifier fixes (Praveen Paneri) - l3 tuning (Imre) - revert mst dp audio, it's totally non-functional and crash-y (Lyude) - first official dmc for kbl (Rodrigo) - and tons of small things all over as usual I've cherry-picked the revert for the nonblocking stuff that landed right before I tagged this over, just to avoid too much confusion. This has a bunch of conflicts because git gets lots with us cherry-picking patches from -next to 4.7. But since it's all cherry-picks you can just pull in with "-X theirs" and it should all work out. Besides that I want a baseline with 4.7, drm-misc and this for a few patch series I also want to backmerge the entire pile into drm-intel-next again this week because of these conflicts. Would be awesome if you can handle all the -next pulls I've sent you on Thu, so that I can do the backmerge on Fri before I do the next tag round. btw Tomi missed 4.7 with his pull, so I'll ping him to get his omapdrm pile out now too to make sure it hits 4.8.

[RFC v2] Change dma_attrs from bitfield to unsigned long
by Krzysztof Kozlowski 01 Jun '16

01 Jun '16

Hi, This is second attempt to bring some safeness to dma_attrs. In v1 [0] I added const to data pointed by attrs. However Christoph Hellwig suggested getting rid of struct dma_attrs in favor of some simpler data type. Benefits of unsigned long for dma_attrs: 1. This is just simpler. Both in terms of reading the code and setting attributes. Instead of initializing local attributes on the stack and passing pointer to it to dma_set_attr(), just set the bits. 2. It brings safeness and checking for const correctness because the attributes are passed by value. The problem is that the patch touches the dma-mapping API so all the users have to be converted (ARM and ARM64 as of now). Any ideas to split it per smaller patches? The work is not finished yet, I would rather get some feedback before progressing further.

Hi Dave, Frist -misc pull for 4.8, with pretty much just random all over plus a few more lockless gem BO patches acked/reviewed by driver maintainers. I'm starting a bit earlier this time around because there's a few invasive patch series to land (nonblocking atomic prep work, fence prep work, rst/sphinx kerneldoc finally happening) and I need a baseline with all the branches merged. Cheers, Daniel The following changes since commit a39ed680bddb1ead592e22ed812c7e47286bfc03: drm/edid: add displayid detailed 1 timings to the modelist.
