Ben Widawsky reported missed IRQ issues and this patch here helps.
We have one other missed IRQ report still left on snb, reported by QA:
https://bugs.freedesktop.org/show_bug.cgi?id=46145
This is _not_ a regression due to the forcewake voodoo though, it
started showing up before that was applie

some quick private discussion releaved that the A-E in these defines are
also per-port. So I think we also need to r
I wanted to run this by folks before I start doing any actual work.
This is primarily for GPGPU, or perhaps *really* accurate rendering
requirements.
IVB+ has an interrupt to tell us when a cacheline seems to be going bad.
There is also a mechanism to remap the bad cachelines. The

badblocks and badram (memmap) both seem to be similar situations. A

RC6 residency should be in intervals of 1.28us, and the counter wraps.
Here is an example using awk to get the various RC6 and RC6+ residency
times in seconds, since boot.
cat /sys/kernel/debug/dri/0/i915_drpc_info | grep residency | awk -F':' -F' '
'{print $5 * 1.28 / 100}'
This is primar
Merge rc6 information into the power group for our device. Until now the
i915 driver has not had any sysfs entries (aside from the connector
stuff enabled by drm core). Since it seems like we're likely to have
more in the future I created a new file for sysfs stubs, as well as the
rc6 sysfs functio

This is meant to test the sysfs entry for showing rc6 residency in
milliseconds. Remember, sysfs is a permanent interface.
v2: use new get_card interface to try "all" devices
check rc6p and rc6pp in addition to rc6
v3: rename rc6_residency.c to sysfs_rc6_residency.c
