Pull drm updates from Dave Airlie: "This seems to have been a comparatively quieter merge window, I assume due to holidays etc. The "biggest" change is AMD header cleanups, which merge/remove a bunch of them. The AMD gpu scheduler is now being made generic with the etnaviv driver wanting to reuse the code, hopefully other drivers can go in the same direction. Otherwise it's the usual lots of stuff in i915/amdgpu, not so much stuff elsewhere. Core: - Add .last_close and .output_poll_changed helpers to reduce driver footprints - Fix plane clipping - Improved debug printing support - Add panel orientation property - Update edid derived properties at edid setting - Reduction in fbdev driver footprint - Move amdgpu scheduler into core for other drivers to use. i915: - Selftest and IGT improvements - Fast boot prep work on IPS, pipe config - HW workarounds for Cannonlake, Geminilake - Cannonlake clock and HDMI2.0 fixes - GPU cache invalidation and context switch improvements - Display planes cleanup - New PMU interface for perf queries - New firmware support for KBL/SKL - Geminilake HW workaround for perforamce - Coffeelake stolen memory improvements - GPU reset robustness work - Cannonlake horizontal plane flipping - GVT work amdgpu/radeon: - RV and Vega header file cleanups (lots of lines gone!) - TTM operation context support - 48-bit GPUVM support for Vega/RV - ECC support for Vega - Resizeable BAR support - Multi-display sync support - Enable swapout for reserved BOs during allocation - S3 fixes on Raven - GPU reset cleanup and fixes - 2+1 level GPU page table amdkfd: - GFX7/8 SDMA user queues support - Hardware scheduling for multiple processes - dGPU prep work rcar: - Added R8A7743/5 support - System suspend/resume support sun4i: - Multi-plane support for YUV formats - A83T and LVDS support msm: - Devfreq support for GPU tegra: - Prep work for adding Tegra186 support - Tegra186 HDMI support - HDMI2.0 and zpos support by using generic helpers tilcdc: - Misc fixes omapdrm: - Support memory bandwidth limits - DSI command mode panel cleanups - DMM error handling exynos: - drop the old IPP subdriver. etnaviv: - Occlusion query fixes - Job handling fixes - Prep work for hooking in gpu scheduler armada: - Move closer to atomic modesetting - Allow disabling primary plane if overlay is full screen imx: - Format modifier support - Add tile prefetch to PRE - Runtime PM support for PRG ast: - fix LUT loading" * tag 'drm-for-v4.16' of git://people.freedesktop.org/~airlied/linux: (1471 commits) drm/ast: Load lut in crtc_commit drm: Check for lessee in DROP_MASTER ioctl drm: fix gpu scheduler link order drm/amd/display: Demote error print to debug print when ATOM impl missing dma-buf: fix reservation_object_wait_timeout_rcu once more v2 drm/amdgpu: Avoid leaking PM domain on driver unbind (v2) drm/amd/amdgpu: Add Polaris version check drm/amdgpu: Reenable manual GPU reset from sysfs drm/amdgpu: disable MMHUB power gating on raven drm/ttm: Don't unreserve swapped BOs that were previously reserved drm/ttm: Don't add swapped BOs to swap-LRU list drm/amdgpu: only check for ECC on Vega10 drm/amd/powerplay: Fix smu_table_entry.handle type drm/ttm: add VADDR_FLAG_UPDATED_COUNT to correctly update dma_page global count drm: Fix PANEL_ORIENTATION_QUIRKS breaking the Kconfig DRM menuconfig drm/radeon: fill in rb backend map on evergreen/ni. drm/amdgpu/gfx9: fix ngg enablement to clear gds reserved memory (v2) drm/ttm: only free pages rather than update global memory count together drm/amdgpu: fix CPU based VM updates drm/amdgpu: fix typo in amdgpu_vce_validate_bo ...

It was only checking the divider when determing the closest match if it could not match the requested rate exactly. For a projector connected to an Olimex A20-OLinuXino-LIME using HDMI with a native resolution of 1280x800 and pixel clock of 83.5 MHz, this resulted in 1280x800 mode not being available and the following in dmesg when the kernel is booted with drm.debug=0x3e: [drm:drm_mode_debug_printmodeline] Modeline 37:"1280x800" 60 83500 1280 1352 1480 1680 800 810 816 831 0x48 0x5 [drm:drm_mode_prune_invalid] Not using 1280x800 mode: NOCLOCK Fixes: 9c5681011a0c ("drm/sun4i: Add HDMI support") Signed-off-by: Jonathan Liu <net147@gmail.com> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180109020323.11852-4-net147@gmail.com

2018-01-11drm/sun4i: hdmi: Check for unset best_parent in sun4i_tmds_determine_rateJonathan Liu
It is possible that if there is no exact rate match and "rounded = clk_hw_round_rate(parent, ideal)" gives high enough values (e.g. if rounded is 2 * ideal) that the condition "abs(rate - rounded / i) < abs(rate - best_parent / best_div)" is never met and best_parent is never set. This results in req->rate and req->best_parent_rate being assigned 0. To avoid this, we set best_parent to the first calculated rate if it is unset. The sun4i_tmds_calc_divider function already has a similar check.

2017-12-20drm/sun4i: hdmi: Move the mode_valid callback to the encoderMaxime Ripard
When attached to the connector, the mode_valid callback will only filter the modes provided by the connector itself as part of its probe. However, it will not be doing it when the mode is provided by the userspace, which still might result in a broken configuration. In order to enforce these constraints, move our mode_valid callback to the encoder which doesn't have this behaviour.

The commit 4c7f16d14a33 ("drm/sun4i: Fix TCON clock and regmap initialization sequence") moved a bunch of logic around, but forgot to update the gotos after the introduction of the err_free_dotclock label. It means that if we fail later that the one introduced in that commit, we'll just to the old label which isn't free the clock we created. This will result in a breakage as soon as someone tries to do something with that clock, since its resources will have been long reclaimed.

2017-12-15drm/sun4i: validate modes for HDMIHans Verkuil
When I connected my cubieboard running 4.15-rc1 to my 4k display I got no picture. Some digging found that there is no check against the upper pixelclock limit of the HDMI output, so X selects a 4kp60 format at 594 MHz, which obviously won't work. The patch below adds a check for the upper bound of what this hardware can do, and it checks if the requested tmds clock can be obtained. It also allows for the +/- 0.5% pixel clock variation that the HDMI spec permits. That code is based on commit 22d0be2a557e ("drm: arcpgu: Allow some clock deviation in crtc->mode_valid() callback") from Jose Abreu for drm/arc.

Premultiply and color key control registers are already set to zero by initialization code few lines above. Furthermore, it seems that colorkeying doesn't really work. It's not used in BSP driver and experiments with it all failed. Just remove the code.

2017-12-05drm/sun4i: Remove setting alpha mode in DE2 driverJernej Skrabec
Current code sets alpha mode to global alpha mode and global alpha value to 0xff which is totaly opaque. That is not needed for two reasons: - only one plane is active and thus it can be blended only with background, which is black, - it will hinder proper blending when more than one plane is supported Default mode (0) considers pixel alpha value or 0xff if pixel has no alpha information. Global alpha value is ignored in this case. Because of that, just remove the code.

2017-11-30drm/sun4i: use sun4i_tcon_of_table to check if a device node is a TCONChen-Yu Tsai
The sun4i DRM driver maintains a list of compatible strings it uses to check if a device node within the display component graph is a TCON. The TCON driver also has this list, used to bind the TCON driver to the device. These two lists are identical. Instead of maintaining two identical lists, export the list from the TCON driver for the DRM driver to use.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.
