2013-05-31drm, agpgart: Use pgprot_writecombine for AGP maps and make the MTRR optionalAndy Lutomirski4-22/+15
I'm not sure I understand the intent of the previous behavior. mmap on /dev/agpgart and DRM_AGP maps had no cache flags set, so they would be fully cacheable. But the DRM code (most of the time) would add a write-combining MTRR that would change the effective memory type to WC. The new behavior just requests WC explicitly for all AGP maps. If there is any code out there that expects cacheable access to the AGP aperture (because the drm driver doesn't request an MTRR or because it's using /dev/agpgart directly), then it will now end up with a UC or WC mapping, depending on the architecture and PAT availability. But cacheable access to the aperture seems like it's asking for trouble, because, AIUI, the aperture is an alias of RAM.

2013-05-31drm: Update drm_addmap and drm_mmap to use PAT WC instead of MTRRsAndy Lutomirski2-21/+21
Previously, DRM_FRAME_BUFFER mappings, as well as DRM_REGISTERS mappings with DRM_WRITE_COMBINING set, resulted in an unconditional MTRR being added but the actual mappings being created as UC-. Now these mappings have the MTRR added only if needed, but they will be mapped with pgprot_writecombine. The non-WC DRM_REGISTERS case now uses pgprot_noncached instead of hardcoding the bit twiddling. The DRM_AGP case is unchanged for now.

2013-05-31drm (ast, cirrus, mgag200, nouveau, savage, vmwgfx): Remove drm_mtrr_{add, del}Andy Lutomirski7-78/+35
This replaces drm_mtrr_{add,del} with arch_phys_wc_{add,del}. The interface is simplified (because the base and size parameters to drm_mtrr_del never did anything), and it no longer adds MTRRs on systems that don't need them.

2013-05-22drm/i915: avoid premature DP AUX timeoutsImre Deak2-2/+3
During DP AUX communication we might time out 1 jiffy too early, because the calculated expiry jiffy value is one less than needed. This is only one reason for false DP AUX timeouts. For a complete solution we also need the following fix, which is now queued for mainline: http://marc.info/?l=linux-kernel&m=136748515710837&w=2 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=64133 Signed-off-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-05-22drm/i915: avoid premature timeouts in __wait_seqno()Imre Deak1-1/+1
At the moment wait_event_timeout/wait_event_interruptible_timeout may time out 1 jiffy too early, as the calculated expiry time is 1 less than needed. Besides timing out too early this also means that the calculation of the remaining time will be incorrect and we will pass a non-zero remaining time to user space in case of a time out.

2013-05-22drm/i915: add msecs_to_jiffies_timeout to guarantee minimum durationImre Deak1-0/+15
We need this to avoid premature timeouts whenever scheduling a timeout based on the current jiffies value. For an explanation see [1]. The following patches will take the helper into use. Once the more generic solution proposed in the thread at [1] is accepted this patch can be reverted while keeping the follow-up patches.

2013-05-22drm/i915: force full modeset if the connector is in DPMS OFF modeImre Deak1-2/+22
Currently the driver's assumed behavior for a modeset with an attached FB is that the corresponding connector will be switched to DPMS ON mode if it happened to be in DPMS OFF (or another power save mode). This wasn't enforced though if only the FB changed, everything else (format, connector etc.) remaining the same. In this case we only set the new FB base and left the connector in the old power save mode. Fix this by forcing a full modeset whenever there is an attached FB and any affected connector is in a power save mode. V_2: Run the test for encoders in power save mode outside the the test for fb change: user space may have just disabled the encoders but left everything else in place. Make sure the connector list is not empty before running this test.
