2021-08-12docs: sphinx-requirements: Move sphinx_rtd_theme to topAkira Yokosawa1-2/+1
sphinx_rtd_theme 0.5.2 has "docutils<0.17" in its requirements. docutils 0.17 released this April caused regression in sphinx_rtd_theme 0.5.1 [1]. By removing docutils and moving sphinx_rtd_theme before Sphinx in requirements.txt, the requirement of "docutils<0.17" can be met naturally.

2021-08-12docs: pdfdocs: One-half spacing for CJK translationsAkira Yokosawa3-2/+26
CJK documents are much easier to read with a wider baseline stretch. Applying onehalfspacing option of "setspace" package looks reasonable. Note: \usepackage{setspace} needs to be before that of hyperref in the preamble. The 'extrapackages' key (available since Sphinx 2.3) is for this purpose. For systems with Sphinx < 2.3, dummy commands of \onehalfspacing and \singlespacing are provided instead. One-half spacing is not effective in LaTeX sources generated by such revisions of Sphinx.

2021-08-12docs: pdfdocs: Add conf.py local to translations for ascii-art alignmentAkira Yokosawa1-0/+12
Globally choosing "Noto Sans Mono CJK SC" would result in sub-optimal look of literal blocks in Latin documents. Therefore, localize the font choice to translations by adding conf.py under Documentation/translations/. The local conf.py is enabled when the command: make SPHINXDIRS=translations pdfdocs is used to build the PDF. Resulting translations.pdf (under Documentation/output/translations/pdf) will have properly aligned ascii-art figures. NOTE: There remain mis-aligned ascii-art figures in Korean translations. This is due to the font designer's decision to assign slightly narrower widths (920) to Hangul characters in "Noto Sans Mono CJK KR" than those of Hanja (Hanzi/Kanji) characters (1000) [1].

"Noto Serif CJK SC" and its variants suit better with the roman font of Latin letters. On some distros such as Fedora, it is possible to partially install "Noto Sans CJK" fonts. So, if the Serif fonts are not found on the system, fall back to the Sans fonts.

2021-08-12docs: pdfdocs: Add CJK-language-specific font settingsAkira Yokosawa4-1/+62
zh_TW, ko_KR, and ja_JP translations have their preferred glyph sets different from that of zh_CN. To switch CJK font in the middle of the translations, introduce custom LaTeX macros listed below: \kerneldocBeginSC \kerneldocEndSC \kerneldocBeginTC \kerneldocEndTC \kerneldocBeginKR \kerneldocEndKR \kerneldocBeginJP \kerneldocEndJP , and embed a pair of macros in each language's index.rst. NOTE 1: Update of zh_TW/index.rst is deferred to a follow-up change. NOTE 2: Custom macros added here do not imply \kerneldocCJK(on|off). This is intentional. For example, \kerneldocCJKoff needs to be at the top of Italian translations' index.rst for the footer of final zh_TW page to be properly typeset.

To make generated LaTeX code portable across systems with different sets of available fonts, convert font-availability check in python code to LaTeX code by using a conditional command provided by the "fontspec" package. This will help those who run Sphinx on one machine/container and run latexmk on other machines/containers. Remove import of check_output as it is unused any more.

2021-08-12x86/reboot: Document how to override DMI platform quirksPaul Gortmaker2-1/+8
commit 5955633e91bf ("x86/reboot: Skip DMI checks if reboot set by user") made it so that it's not required to recompile the kernel in order to bypass broken reboot quirks compiled into an image: * This variable is used privately to keep track of whether or not * reboot_type is still set to its default value (i.e., reboot= hasn't * been set on the command line). This is needed so that we can * suppress DMI scanning for reboot quirks. Without it, it's * impossible to override a faulty reboot quirk without recompiling. However, at the time it was not eally documented outside the source code, and so this information isn't really available to the average user out there. The change is a little white lie and invented "reboot=default" since it is easy to remember, and documents well. The truth is that any random string that is *not* a currently accepted string will work. Since that doesn't document well for non-coders, and since it's unknown what the future additions might be, lay claim on "default" since that is exactly what it achieves.

We still have quite a bit more work to do with overall reworking of the ttm-based dg1 code, but the uapi stuff is now finalized with the latest pull. So remove that. This also fixes kerneldoc build warnings because we've included the same headers in two places, resulting in sphinx complaining about duplicated symbols. This regression has been created when we moved the uapi definitions to the real include/uapi/ folder in 727ecd99a4c9 ("drm/doc/rfc: drop the i915_gem_lmem.h header") v2: Fix a few references that I missed, the htmldocs build took forever.

ssh://git.freedesktop.org/git/drm/drm-intel into drm-next UAPI Changes: - Add I915_MMAP_OFFSET_FIXED On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid type. On devices without local memory, this caching mode is invalid. As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will be used, depending on the object placement on creation. WB will be used when the object can only exist in system memory, WC otherwise. Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888 - Reinstate the mmap ioctl for (already released) integrated Gen12 platforms Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is still to sunset the IOCTL even for integrated and require using mmap_offset. - Reject caching/set_domain IOCTLs on discrete Expected to become immutable property of the BO - Disallow changing context parameters after first use on Gen12 and earlier - Require setting context parameters at creation on platforms after Gen12 Rationale (for both): Allow less dynamic changes to the context to simplify the implementation and avoid user shooting theirselves in the foot. - Drop I915_CONTEXT_PARAM_RINGSIZE Userspace PR for compute-driver has not been merged - Drop I915_CONTEXT_PARAM_NO_ZEROMAP Userspace PR for libdrm / Beignet was never landed - Drop CONTEXT_CLONE API Userspace PR for Mesa was never landed - Drop getparam support for I915_CONTEXT_PARAM_ENGINES Only existed for symmetry wrt. setparam, never used. - Disallow bonding of virtual engines Drop the prep work, no hardware has been released needing it. - (Implicit) Disable gpu relocations Media userspace was the last userspace to still use them.

2021-08-11dt-bindings: pinctrl: mt8195: Use real world values for drive-strength argumentsChen-Yu Tsai1-4/+1
The original binding submission for MT8195 pinctrl described the possible drive strength values in micro-amps in its description, but then proceeded to list register values in its device tree binding constraints. However, the macros used with the Mediatek pinctrl bindings directly specify the drive strength in micro-amps, instead of hardware register values. The current driver implementation in Linux does convert the value from micro-amps to hardware register values. This implementation is also used with MT7622 and MT8183, which use real world values in their device trees. Given the above, it was likely an oversight to use the raw register values in the binding. Correct the values in the binding. Also drop the description since the binding combined with its parent, pinctrl/pincfg.yaml, the binding is now self-describing.
