[PATCH] Fix uninitialised spinlock in via-pmu-backlight code.

2006-11-04T01:33:45+00:00

The uninitialised pmu_backlight_lock causes the current Fedora test kernel (which has spinlock debugging enabled) to panic on suspend. This is suboptimal, so I fixed it.

[PATCH] backlight last round of fixes

2006-09-01T18:39:10+00:00

Fix some more problems (inverted use of semaphores in some places). He also moved my checks into within the protected section which is better. Signed-off-by: Michael Hanselmann Signed-off-by: Benjamin Herrenschmidt Cc: "Antonino A. Daplas" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] powerpc: More via-pmu backlight fixes

2006-09-01T18:39:09+00:00

The via-pmu backlight code (introduced in 2.6.18) has various design issues causing crashes on machines using it like the old Wallstreet powerbook (Michael, the author, never managed to test on these and I just got my hand on one of those old beasts). This fixes them by no longer trying to hijack the backlight device of the frontmost framebuffer (causing that framebuffer to crash) but having it's own local bits instead. Might look weird but it's better that way on those old machines, at least as a last-minute fix for 2.6.18. We might rework the whole thing later. This patch also changes the way it gets notified of sleep and wakeup in order to properly shut the backlight down on sleep and bring it back on wakeup.

[PATCH] powermac: More powermac backlight fixes

2006-07-31T20:28:45+00:00

This patch fixes several problems: - The legacy backlight value might be set at interrupt time. Introduced a worker to prevent it from directly calling the backlight code. - via-pmu allows the backlight to be grabbed, in which case we need to prevent other kernel code from changing the brightness. - Don't send PMU requests in via-pmu-backlight when the machine is about to sleep or waking up. - More Kconfig fixes.

[POWERPC] Xserve G5 thermal control fixes

2006-07-28T00:42:49+00:00

The thermal control for the Xserve G5s had a few issues. For one, the way to program the RPM fans speeds into the FCU is different between it and the desktop models, which I didn't figure out until recently, and it was missing a control loop for the slots fan, running it too fast. Both of those problems were causing the machine to be much more noisy than necessary. This patch also changes the fixed value of the slots fan for desktop G5s to 40% instead of 50%. It seems to still have a pretty good airflow that way and is much less noisy. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] fix up front-LED Kconfig

2006-07-25T15:26:08+00:00

This patch fixes the front-LED Kconfig issues I introduced while creating it. Apparently having a dependency isn't enough to have the select not evaluated or something like that. The patch also changes the default configuration for pmac32 select the default for the LED to be the IDE trigger. While I was at it, I completely updated the defconfig and also added snd-aoa to it.

[PATCH] powermac: Combined fixes for backlight code

2006-07-10T20:24:20+00:00

This patch fixes several problems: - pmac_backlight_key() is called under interrupt context, and therefore can't use mutexes or semaphores, so defer the backlight level for later, as it's not critical (original code by Aristeu S. Rozanski F. ). - Add exports for functions that might be called from modules - Fix Kconfig depdencies on PMAC_BACKLIGHT. - Fix locking issues on calls from inside the driver (reported by Aristeu S. Rozanski F., too) - Fix wrong calculation of backlight values in some of the drivers - Replace pmac_backlight_key_up/down by inline functions [akpm@osdl.org: fix function prototypes] Signed-off-by: Michael Hanselmann Acked-by: Aristeu S.

[PATCH] powerpc: fix SMU driver interrupt mapping

2006-07-10T20:24:20+00:00

The SMU driver tries to map an interrupt from the device-tree before the interrupt controllers in the machine have been enumerated. This doesn't work properly and cause machines like the Quad g5 to fail booting later on when some drivers waits endlessly for an SMU request to complete. This is the second problem preventing boot on the Quad g5. This fixes it and also makes the SMU driver a bit more resilient to not having an interrupt.
