| | | | | | | | | | | | | | | | | | The 3rd LED on this board is something like a power-led, it is on all the time. With this change to the leds-wrap driver it is possible to use this LED too. Signed-off-by: Michael Loeffler <zvpunry@zvpunry.de> Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
| * leds: Fix led-gpio active_low default brightnessRaphael Assenat2008-02-07
| | | | | | | | | | | | | | | | | | | | When gpio_direction_output() is called, led_dat->active_low is used as default value. This means that the led will always be off by default. cdev.brightness should really have been set to LED_OFF unconditionally to reflect this behavior.

| * | mga_dma: return 'err' not just zero from mga_do_cleanup_dma()Jesper Juhl2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While reading some code I stumbled across the use of 'err' in drivers/char/drm/mga_dma.c::mga_do_cleanup_dma() and I think there's a small problem. The variable is only used inside #if __OS_HAS_AGP which is fine, but all that ever happens is an assignment to the variable - it is never actually used for anything. The variable is nicely initialized to zero which is also what the return statement at the end of function returns (always at the moment). It looks to me like that function should be returning 'err' instead of always just returning 0. Here's a patch to do that.

| * | [CPUFREQ] Eliminate cpufreq_userspace scaling_setspeed deadlockVenki Pallipadi2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eliminate cpufreq_userspace scaling_setspeed deadlock. Luming Yu recently uncovered yet another cpufreq related deadlock. One thread that continuously switches the governors and the other thread that repeatedly cats the contents of cpufreq directory causes both these threads to go into a deadlock. Detailed examination of the deadlock showed the exact flow before the deadlock as: Thread 1 Thread 2 ________ ________ cats files under /sys/devices/.../cpufreq/ Set governor to userspace Adds a new sysfs entry for scaling_setspeed cats files under /sys/devices/.../cpufreq/ Set governor to performance Holds cpufreq_rw_sem in write mode Sends a STOP notify to userspace governor cat /sys/devices/.../cpufreq/scaling_setspeed Gets a handle on the above sysfs entry with sysfs_get_active Blocks while trying to get cpufreq_rw_sem in read mode Remove a sysfs entry for scaling_setspeed Blocks on sysfs_deactivate while waiting for earlier get_active (on other thread) to drain At this point both threads go into deadlock and any other thread that tries to do anything with sysfs cpufreq will also block. There seems to be no easy way to avoid this deadlock as long as cpufreq_userspace adds/removes the sysfs entry under same kobject as cpufreq. Below patch moves scaling_setspeed to cpufreq.c, keeping it always and calling back the governor on read/write. This is the cleanest fix I could think of, even though adding two callbacks in governor structure just for this seems unnecessary. Note that the change makes scaling_setspeed under /sys/.../cpufreq permanent and returns <unsupported> when governor is not userspace.

This new note type is not used by any consumers of core files yet, but support can be added. I don't even have any hardware with SPE capabilities, so I've never seen such a note. But this demonstrates how simple it is to export register information in core dumps when the user_regset style is used for the low-level code.
