  • The contents of those directories were orphaned at the documentation
    body.

    While those directories could likely be moved to be inside some guide,
    I'm opting to just adding their indexes to the main one, removing the
    :orphan: and adding the SPDX header.

    For the drivers, the rationale is that the documentation contains
    a mix of Kernelspace, uAPI and admin-guide. So, better to keep them on
    separate directories, as we've be doing with similar subsystem-specific
    docs that were not split yet.

    For the others, well... I'm too lazy to do the move. Also, it
    seems to make sense to keep at least some of those at the main
    dir (like kbuild, for example). In any case, a latter patch
    could do the move.

  • Rotations and reflections setup are needed in some scenarios to initialise
    properly the initial framebuffer. Some drivers already had a bunch of
    quirks to deal with this, such as either a private kernel command line
    parameter (omapdss) or on the device tree (various panels).

    In order to accomodate this, let's create a video mode parameter to deal
    with the rotation and reflexion.

  • The conversion is actually:
    - add blank lines and identation in order to identify paragraphs;
    - fix tables markups;
    - add some lists markups;
    - mark literal blocks;
    - adjust title markups.

    At its new index.rst, let's add a :orphan: while this is not linked to
    the main index.rst file, in order to avoid build warnings.

    Also, removed the Maintained by, as requested by Geert.

  • This is a respin with a wider audience (all that get_maintainer returned)
    and I know this spams a *lot* of people. Not sure what would be the correct
    way, so my apologies for ruining your inbox.

    The 00-INDEX files are supposed to give a summary of all files present
    in a directory, but these files are horribly out of date and their
    usefulness is brought into question. Often a simple "ls" would reveal
    the same information as the filenames are generally quite descriptive as
    a short introduction to what the file covers (it should not surprise
    anyone what Documentation/sched/sched-design-CFS.txt covers)

    A few years back it was mentioned that these files were no longer really
    needed, and they have since then grown further out of date, so perhaps
    it is time to just throw them out.

    A short status yields the following _outdated_ 00-INDEX files, first
    counter is files listed in 00-INDEX but missing in the directory, last
    is files present but not listed in 00-INDEX.

    List of outdated 00-INDEX:
    Documentation: (4/10)
    Documentation/sysctl: (0/1)
    Documentation/timers: (1/0)
    Documentation/blockdev: (3/1)
    Documentation/w1/slaves: (0/1)
    Documentation/locking: (0/1)
    Documentation/devicetree: (0/5)
    Documentation/power: (1/1)
    Documentation/powerpc: (0/5)
    Documentation/arm: (1/0)
    Documentation/x86: (0/9)
    Documentation/x86/x86_64: (1/1)
    Documentation/scsi: (4/4)
    Documentation/filesystems: (2/9)
    Documentation/filesystems/nfs: (0/2)
    Documentation/cgroup-v1: (0/2)
    Documentation/kbuild: (0/4)
    Documentation/spi: (1/0)
    Documentation/virtual/kvm: (1/0)
    Documentation/scheduler: (0/2)
    Documentation/fb: (0/1)
    Documentation/block: (0/1)
    Documentation/networking: (6/37)
    Documentation/vm: (1/3)

    Then there are 364 subdirectories in Documentation/ with several files that
    are missing 00-INDEX alltogether (and another 120 with a single file and no
    00-INDEX).

    I don't really have an opinion to whether or not we /should/ have 00-INDEX,
    but the above 00-INDEX should either be removed or be kept up to date. If
    we should keep the files, I can try to keep them updated, but I rather not
    if we just want to delete them anyway.

    As a starting point, remove all index-files and references to 00-INDEX and
    see where the discussion is going.

  • Currently fbcon claims fbdevs as soon as they are registered and takes over
    the console as soon as the first fbdev gets registered.

    This behavior is undesirable in cases where a smooth graphical bootup is
    desired, in such cases we typically want the contents of the framebuffer
    (typically a vendor logo) to stay in place as is.

    The current solution for this problem (on embedded systems) is to not
    enable fbcon.

    This commit adds a new FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER config option,
    which when enabled defers fbcon taking over the console from the dummy
    console until the first text is displayed on the console. Together with the
    "quiet" kernel commandline option, this allows fbcon to still be used
    together with a smooth graphical bootup, having it take over the console as
    soon as e.g. an error message is logged.

    Note the choice to detect the first console output in the dummycon driver,
    rather then handling this entirely inside the fbcon code, was made after
    2 failed attempts to handle this entirely inside the fbcon code. The fbcon
    code is woven quite tightly into the console code, making this to only
    feasible option.

  • This adds a new command line option to select the fbcon margin color.

    The motivation for this is screens where black does not blend into the
    physical surroundings of the screen. For example, using an LCD (not the
    backlit kind), white text on a black background is hard to read, so
    inverting the colors is preferred. However, when you do this, most of the
    screen is filled with white but the margins are still filled with black.
    This makes a big, black, backwards 'L' on the screen. By setting
    fbcon=margin:7, the margins will be filled with white and the LCD looks as
    expected.

  • 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.

  • Pull drm updates from Dave Airlie:
    "Okay this is the big one, I was stalled on the fbdev pull req as I
    stupidly let fbdev guys merge a patch I required to fix a warning with
    some patches I had, they ended up merging the patch from the wrong
    place, but the warning should be fixed. In future I'll just take the
    patch myself!

    Outside drm:

    There are some snd changes for the HDMI audio interactions on haswell,
    they've been acked for inclusion via my tree. This relies on the
    wound/wait tree from Ingo which is already merged.

    Major changes:

    AMD finally released the dynamic power management code for all their
    GPUs from r600->present day, this is great, off by default for now but
    also a huge amount of code, in fact it is most of this pull request.

    Since it landed there has been a lot of community testing and Alex has
    sent a lot of fixes for any bugs found so far. I suspect radeon might
    now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable
    dynamic powermanagement for anyone.

    New drivers:

    Renesas r-car display unit.

    Other highlights:

    - core: GEM CMA prime support, use new w/w mutexs for TTM
    reservations, cursor hotspot, doc updates
    - dvo chips: chrontel 7010B support
    - i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
    Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
    support (this time for sure)
    - nouveau: async buffer object deletion, context/register init
    updates, kernel vp2 engine support, GF117 support, GK110 accel
    support (with external nvidia ucode), context cleanups.
    - exynos: memory leak fixes, Add S3C64XX SoC series support, device
    tree updates, common clock framework support,
    - qxl: cursor hotspot support, multi-monitor support, suspend/resume
    support
    - mgag200: hw cursor support, g200 mode limiting
    - shmobile: prime support
    - tegra: fixes mostly

    I've been banging on this quite a lot due to the size of it, and it
    seems to okay on everything I've tested it on."

  • The old code allowed very strange memory types. Now it works like
    all the other video drivers: ioremap_wc is used unconditionally,
    and MTRRs are set if PAT is unavailable (unless MTRR is disabled
    by a module parameter).

    UC, WB, and WT support is gone. If there are MTRR conflicts that prevent
    addition of a WC MTRR, adding a non-conflicting MTRR is pointless; it's
    better to just turn off MTRR support entirely.

    As an added bonus, any MTRR added is freed on unload.

  • Usage of /etc/modprobe.conf file was deprecated by module-init-tools and
    is no longer parsed by new kmod tool. References to this file are
    replaced in Documentation, comments and Kconfig according to the
    context.

    There are also some references to the old /etc/modules.conf from 2.4
    kernels that are being removed.

  • Enables page fault based detection of mmap writes to the framebuffer,
    which allows standard fbdev apps (like the generic fbdev xorg driver)
    to work on DisplayLink devices.

    Not all bugs are shaken out of the fb_defio path of udlfb, but it's
    tantalizingly close, so this seems a good time to enable by default.

    Alternatively, option can be disabled when running with an xorg driver
    that can more directly communicate damaged regions of the framebuffer
    via IOCTL. This is a simpler, higher perf option, when available.

  • By default, udlfb allocates a 2nd buffer to shadow what's across
    the bus on the USB device. It can operate without this shadow,
    but then it cannot tell which pixels have changed, and must send all.

    Saves host memory, but worsens the USB 2.0 bus bottleneck.

    This option allows users in very low memory situations (e.g.
    bifferboard) to optionally turn off this shadow framebuffer.

  • The video= parameter of the DRM drivers supports some additional flags that
    the normal fb drivers do not have. They also allow to limit these flags to
    specific outputs. Both things were previously undocumented.

    Also the parsing of the line had some oddities:
    -A lot of misplaced options were silently ignored or partly rejected instead
    of stopping the parsing immediately
    -The 'R' option is documented to follow the 'M' option if specified. It is not
    documented that 'M' is needed to specify 'R' (also this is the case for normal
    fb drivers). In fact the code is correct for normal fb drivers but wrong for
    DRM ones.
    The old code allowed 'R' only _before_ 'M' (since it parses backwards) and only
    if 'M' is given at all which is not needed for the DRM drivers.
    -the margins option ('m') was parsed but later ignored even if the later
    functions support it.
    -specifying multiple enable options at the same time did not lead to an error.
    -specifying something bogus for horizontal resolution (i.e. other things as
    digits) did not lead to an error but an invalid resolution was used.

    If any errors are encountered the position of the faulting string is now
    printed to the user and the complete mode is ignored. This gives much
    more consistent error behaviour.

    I also removed some useless assignments and changed the local flag variables
    to be bool.
