drm/cirrus: correct register values for 16bpp

2014-02-13T21:48:03+00:00

commit 2510538fa000dd13a3e57b79bf073ffb1748976c upstream.

When the mode is set with 16bpp on QEMU, the output gets totally broken.
The culprit is the bogus register values set for 16bpp, which was likely
copied from from a wrong place.

i915: remove pm_qos request on error

2014-02-13T21:48:03+00:00

commit 22accca01713b13dac386ca90b787aadf88f6551 upstream.

Not removing pm qos request and free memory for it can cause crash,
when some other driver use pm qos. For example, this oops:

BUG: unable to handle kernel paging request at fffffffffffffff8
IP: [] plist_add+0x5b/0xd0

was caused by earlier i915 probe failure:

drm/i915: VLV2 - Fix hotplug detect bits

2014-02-13T21:48:03+00:00

commit 232a6ee9af8adb185640f67fcaaa9014a9aa0573 upstream.

Add new definitions for hotplug live status bits for VLV2 since they're
in reverse order from the gen4x ones.

Changelog:
- Restored gen4 bit definitions
- Added new definitions for VLV2
- Added platform check for IS_VALLEYVIEW() in dp_detect to use the correct
  bit defintions
- Replaced a lost trailing brace for the added switch()

[danvet: Switch to _VLV postfix instead of prefix and regroupg
comments again so that the g4x warning is right next to those defines.
Also add a _G4X suffix for those special ones. Also cc stable.]

drm/i915: Fix the offset issue for the stolen GEM objects

2014-02-13T21:48:03+00:00

commit ec14ba47791965d2c08e0a681ff44eacbf3c4553 upstream.

The 'offset' field of the 'scatterlist' structure was wrongly
programmed with the offset value from the base of stolen area,
whereas this field indicates the offset from where the interested
data starts within the first PAGE pointed to by 'scattterlist'
structure. As a result when a new GEM object allocated from stolen
area is mapped to GTT, it could lead to an overwrite of GTT entries
as the page count calculation will go wrong, refer the function
'sg_page_count'.

v2: Modified the commit message. (Chris)

drm/i915: Flush outstanding requests before allocating new seqno

2014-02-13T21:48:03+00:00

commit 304d695c3dc8eb65206b9eaf16f8d1a41510d1cf upstream.

In very rare cases (such as a memory failure stress test) it is possible
to fill the entire ring without emitting a request. Under this
circumstance, the outstanding request is flushed and waited upon. After
space on the ring is cleared, we return to emitting the new command -
except that we just cleared the seqno allocated for this operation and
trigger the sanity check that a request is only ever emitted with a
valid seqno. The fix is to rearrange the code to make sure the
allocation of the seqno for this operation is after any required flushes
of outstanding operations.

The bug exists since the preallocation was introduced in
