  • dc762c4f8   staging: sm7xx: Use kernel framebuffer mode setting ... Browse Code »

    This patch implements dynamic framebuffer mode setting.

    Previous code works with mode setting in a hard code way. Previous hard
    code configuration is used as default configuration if dynamic mode
    setting or boot mode setting (via sm712vga_setup) is not used.

    Tested with SM712 supporting 1024x600x16 as default hardware resolution.

    Changes:

    - Implement fb_check_var and fb_set_par callbacks
    - Remove __maybe_unused decorator in function being used (sm712vga_setup)
    - Minor cleanup on initialization structs related with mode settings
    - Updated author copyright
    - Updated TODO file

  • ac751efa6   console: rename acquire/release_console_sem() to console_lock/unlock() ... Browse Code »

    The -rt patches change the console_semaphore to console_mutex. As a
    result, a quite large chunk of the patches changes all
    acquire/release_console_sem() to acquire/release_console_mutex()

    This commit makes things use more neutral function names which dont make
    implications about the underlying lock.

    The only real change is the return value of console_trylock which is
    inverted from try_acquire_console_sem()

    This patch also paves the way to switching console_sem from a semaphore to
    a mutex.

    no longer use pci_restore_state() at all (and that caused trivial
    conflicts with the "make pci_restore_state return void" patch)

  • 1d3c16a81   PCI: make pci_restore_state return void ... Browse Code »

    pci_restore_state only ever returns 0, thus there is no benefit in
    having it return any value. Also, a large majority of the callers do
    not check the return code of pci_restore_state. Make the
    pci_restore_state a void return and avoid the overhead.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

    support, the whole system may hang. for example, when copying some files
    from another machine to YeeLoong netbook with the sm7xx video driver via
    scp and when the screen output is enabled, the system may hang.

    Before the bug is fixed, remove the 2D acceleration!

    Yeeloong netbook has a sm712 video card, need this driver, but it is not
    ready to upstream yet, so, go to drivers/staing at first.

    This source code is originally from Silicon Motion Technology Corp, and
    maintained at http://dev.lemote.com/code/linux_loongson for YeeLoong
    netbook. I have done a lot of cleanups for it and merged it into my git
    repository at http://dev.lemote.com/code/rt4ls.

    Thanks to Simon for testing it on a little-endian x86 platform.

    Thanks to Olivier Croset for
    reporting the problem about __BIG_ENDIAN compiling problem and send a
    relative patch.

    The suspend/resume and blank support are contributed by Jason from
    Silicon Motion Technology.
