  • 1a1e0a80c   sound: oss: dmasound: kill SLEEP() macro to avoid race ... Browse Code »

    The use of interruptible_sleep_on_timeout in the dmasound driver
    is questionable and we want to kill off all sleep_on variants.
    This replaces the calls with wait_event_interruptible_timeout
    where possible, to wait for a particular event instead of blocking
    in a racy way. In the sq_write function, the easiest solution is
    an open-coded prepare_to_wait loop.

  • 645ef9ef1   sound: autoconvert trivial BKL users to private mutex ... Browse Code »

    The usage of the BKL in the OSS sound drivers is
    trivial, and each of them only locks against itself,
    so it can be turned into per-driver mutexes.

    This is the script that was used for the conversion:

    file=$1
    name=$2
    if grep -q lock_kernel ${file} ; then
    if grep -q 'include.*linux.mutex.h' ${file} ; then
    sed -i '/include.*/d' ${file}
    else
    sed -i 's/include.*.*$/include /g' ${file}
    fi
    sed -i ${file} \
    -e "/^#include.*linux.mutex.h/,$ {
    1,/^\(static\|int\|long\)/ {
    /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex);

    } }" \
    -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \
    -e '/[ ]*cycle_kernel_lock();/d'
    else
    sed -i -e '/include.*\/d' ${file} \
    -e '/cycle_kernel_lock()/d'
    fi

  • 90dc763fe   sound: push BKL into open functions ... Browse Code »

    This moves the lock_kernel() call from soundcore_open
    to the individual OSS device drivers, where we can deal
    with it one driver at a time if needed, or just kill
    off the drivers.

    All core components in ALSA already provide
    adequate locking in their open()-functions
    and do not require the big kernel lock, so
    there is no need to add the BKL there.

  • 4b30fbde9   oss: fix O_NONBLOCK in dmasound_core ... Browse Code »

    We broke O_NONBLOCK handling in OSS dmasound_core in 2.3.11-pre3 - the
    original code copied f_flags to open_mode and then checked for
    O_NONBLOCK in there, but that got changed to copying f_mode and
    O_NONBLOCK has not reached that field in any kernel version.

    Since we do not care for any other bits, the fix is obvious...

  • 9c2e08c59   [PATCH] mark struct file_operations const 9 ... Browse Code »

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

    MODULE_PARM was actually breaking: recent gcc version optimize them out as
    unused. It's time to replace the last users, which are generally in the
    most unloved drivers anyway.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
