2014-10-16drm/radeon: fix vm page table block size calculationAlex Deucher1-1/+1
The page offset is 12 bits. For example if we have an 8 GB VM, we'd need 33 bits. The number of bits needed for PD + PT is 21 (33 - 12 or log2(8) + 18), not 20 (log2(8) + 17). Noticed by Alexey during code review. Signed-off-by: Alex Deucher <[email protected]> Cc: [email protected]
2014-10-16drm/ttm: Don't evict BOs outside of the requested placement rangeMichel Dänzer1-3/+17
The radeon driver uses placement range restrictions for several reasons, in particular to make sure BOs in VRAM can be accessed by the CPU, e.g. during a page fault. Without this change, TTM could evict other BOs while trying to satisfy the requested placement, even if the evicted BOs were outside of the requested placement range. Doing so didn't free up any space in the requested placement range, so the (potentially high) eviction cost was incurred for no benefit. Nominating for stable because radeon driver changes in 3.17 made this much more noticeable than before.

2014-10-13drm/mst: rework payload table allocation to conform better.Dave Airlie2-20/+59
The old code has problems with the Dell MST monitors due to some assumptions I made that weren't true. I initially thought the Virtual Channel Payload IDs had to be in the DPCD table in ascending order, however it appears that assumption is bogus. The old code also assumed it was possible to insert a member into the table and it would move other members up, like it does when you remove table entries, however reality has shown this isn't true. So the new code allocates VCPIs separate from entries in the payload tracking table, and when we remove an entry from the DPCD table, I shuffle the tracking payload entries around in the struct. This appears to make VT switch more robust (still not perfect) with an MST enabled Dell monitor. Signed-off-by: Dave Airlie <[email protected]>

On destruction the final value is written, to prevent another source of accidental wraparound in case of a channel being destroyed after a hang, and unblocking any other channel that may wait on the about-to-be-deleted channel to signal. I'm nothing if not optimistic about any hope of recovery from that. ;-) Reported-by: Ted Percival <[email protected]> Signed-off-by: Maarten Lankhorst <[email protected]> Tested-by: Ted Percival <[email protected]> Acked-by: Ben Skeggs <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

2014-09-29drm/i915: Do not store the error pointer for a failed userptr registrationChris Wilson1-8/+16
If we fail to create our mmu notification, we report the error back and currently store the error inside the i915_mm_struct. This not only causes subsequent registerations of the same mm to fail (an issue if the first was interrupted by a signal and needed to be restarted) but also causes us to eventually try and free the error pointer.

2014-09-29Revert "drm/i915/bdw: BDW Software Turbo"Daniel Vetter5-241/+39
This reverts commit c76bb61a71083b2d90504cc6d0dda2047c5d63ca. It's apparently too broken so that Rodrigo submitted a patch to add a config option for it. Given that the design is also ... suboptimal and that I've only merged this to get lead engineers and managers off my back for one second let's just revert this. /me puts on combat gear again It was worth a shot ...
