[PATCH 7/7] omap3: make coresight register save across OFF modes a sysfs option
This adds a sysfs file at /sys/power/coresight_save which is used to control if the ETM and debug components' states should be saved and restored across OFF modes.

[PATCH 4/7] etm: do a dummy read from OSSRR during initialization
The first read from ETM OS save and restore register after the power down bit deassertion returns garbage.

[PATCH 6/7] save and restore etm state across core OFF modes
This prevents ETM stalls whenever core enters OFF mode. Original patch author is Richard Woodruff <r-woodruff2(a)ti.com>. This version of the patch makes use of the ETM OS save/restore mechanism, which takes about 55 words in omap3_arm_context[] instead of 128. Also, saving ETM context can be switched on/off at run... 25 Jul 2010 14:02

[PATCH 1/7] coresight: move struct tracectx inside etm driver
This is done so as to be able to make use of the coresight components' registers in assembler code (like omap sleep code). Also, there shouldn't be any users of this structure outside the etm driver.

[PATCH] cyber2000fb: fix machine hang on module load
Hello, I was testing two CyberPro 2000 based PCI cards on x86 and the machine always hanged completely when the cyber2000fb module was loaded. It seems that the card hangs when some registers are accessed too quickly after writing RAMDAC control register. With this patch, both card work. Add delay after RAMDAC c... 25 Jul 2010 14:02

[drm:i915_do_wait_request] *ERROR* i915_do_wait_request
Hi, I tried to run Xorg w/o dri on my notebook. Some time afterwards, a couple of suspend/resume cycles later, X crashed, showing ugly screens of horizontal and vertical stripes all over. Is this solely due to a X/dri bug? Shouldn't it be possible to run X w/o dri? Or might this indicate failing hardware, ma... 25 Jul 2010 12:58
