* ALSA: usbaudio - use printf format instead of hardcoding itAndreas Bergmeier2009-01-271-7/+7
| | | | | | | | Rather use printf format instead of hardcoding prefix like 0x. A next step would be to predefine certain formats. Signed-off-by: Andreas Bergmeier <lcid-fire@gmx.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* sound: usb-audio: make URB sizes more equalClemens Ladisch2009-01-261-24/+5
| | | | | | | | | | Distribute the packets evenly among the URBs, instead of making all URBs except the last one to have the maximum size. This makes the timing of pointer updates more regular and removes some special cases from the code. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* sound: usb-audio: limit playback queue lengthClemens Ladisch2009-01-261-1/+8
| | | | | | | | | | Once our URBs contain enough packets, queueing more URBs does not give us any additional underrun protection (as we use double-buffering) but just increases latency unnecessarily. Therefore, we try to limit the queue length to some reasonable value. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* sound: usb-audio: use normal number of frames for no-data URBsClemens Ladisch2009-01-261-3/+3
| | | | | | | | | | When sending a silence URB (before playback has started, or when it is paused), use the number of frames that would be normally sent instead of a single frame so that the rate at which completion interrupts arrive is consistent.

| * async: fix __lowest_in_progress()Arjan van de Ven2009-01-121-5/+16
| | | | | | | | | | | | | | | | | | | | | | At 37000 feet somewhere near Greenland I woke up from a half-sleep with the realisation that __lowest_in_progress() is buggy. After landing I checked and there were indeed 2 problems with it; this patch fixes both: * The order of the list checks was wrong * The locking was not correct.

| * script: improve markup_oops.pl to also decode oopses in modulesArjan van de Ven2009-01-121-9/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There has been some light flamewar on lkml about decoding oopses in modules (as part of the crashdump flamewar). Now this isn't rocket science, just the markup_oops.pl script cheaped out and didn't handle modules. But really; a flamewar all about that?? What happened to C++ in the kernel or reading files from inside the kernel? This patch adds module support to markup_oops.pl; it's not the most pretty perl but it works for my testcases...

The problem was in some new code that attempted to handle the case where a system is shut down while rcutorture is still running, for example, when rcutorture is built into the kernel so that it cannot be removed. The fix causes the rcutorture threads to "park" in an schedule_timeout_uninterruptible(MAX_SCHEDULE_TIMEOUT) rather than trying to get them to terminate cleanly. Concurrent shutdown and rmmod is illegal. I believe that this is 2.6.29 material, as it is used in some testing setups. For reference, here are the rcutorture operating modes: CONFIG_RCU_TORTURE_TEST=m This is the normal rcutorture build. Use "modprobe rcutorture" (with optional arguments) to start, and "rmmod rcutorture" to stop. If you shut the system down without doing the rmmod, you should see console output like: rcutorture thread rcu_torture_writer parking due to system shutdown One for each rcutorture kthread. CONFIG_RCU_TORTURE_TEST=y CONFIG_RCU_TORTURE_TEST_RUNNABLE=n Use this if you want rcutorture built in, but don't want the test to start running during early boot. To start the torturing: echo 1 > /proc/sys/kernel/rcutorture_runnable To stop the torturing, s/1/0/ You will get "parking" console messages as noted above when you shut the system down. CONFIG_RCU_TORTURE_TEST=y CONFIG_RCU_TORTURE_TEST_RUNNABLE=y Same as above, except that the torturing starts during early boot. Only for the stout of heart and strong of stomach. The same /proc entry noted above may be used to control the test. Located-by: Eric Sesterhenn <snakebyte@gmx.de> Tested-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: Paul E.

To configure wakeup sources, a subtree for the demoboards is created under /sys/power/db1x: sys/ `-- power `-- db1x |-- gpio0 |-- gpio1 |-- gpio2 |-- gpio3 |-- gpio4 |-- gpio5 |-- gpio6 |-- gpio7 |-- timer |-- timer_timeout |-- wakemsk `-- wakesrc The nodes 'gpio[0-7]' and 'timer' configure the GPIO0..7 and M2 bits of the SYS_WAKEMSK (wakeup source enable) register. Writing '1' enables a wakesource, 0 disables it. The 'timer_timeout' node holds the timeout in seconds after which the TOYMATCH2 event should wake the system. The 'wakesrc' node holds the SYS_WAKESRC register after wakeup (in hex), the 'wakemsk' node can be used to get/set the wakeup mask directly. For example, to have the timer wake the system after 10 seconds of sleep, the following must be done in userspace: echo 10 > /sys/power/db1x/timer_timeout echo 1 > /sys/power/db1x/timer echo mem > /sys/power/sleep This patch also removes the homebrew CPU frequency switching code. I don't understand how it could have ever worked reliably; it does not communicate the clock changes to peripheral devices other than uarts.

As a nice side effect, this also enables use of the 'wait' instruction for runtime idle power savings. If the counters aren't enabled/working properly, fall back on the cp0 counter clock code.

This patch renames the core cp0 counter clocksource / clockevent functions from mips_* to r4k_* and updates the wrappers in asm-mips/time.h to call these renamed functions instead. Chips which can detect whether it is safe to use a chip-specific timer can now fall back on the cp0 counter if necessary and possible (e.g. Alchemy with a follow-on patch). Existing behaviour is not changed in any way. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
