drm/radeon: make some dpm errors debug only

"Could not force DPM to low", etc. is usually harmless and just confuses users. Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/nouveau/nvif: allow userspace access to its own client object

drm/nouveau/gr/gf100-: fix oops when calling zbc methods

Somehow missed these two when removing dodgy void casts during the rework. Signed-off-by: Ben Skeggs

drm/nouveau/gr/gf117-: read NV_PGRAPH_GPC_GPM_PD_PES_TPC_ID_MASK from correct GPC

2015-11-25T05:31:21Z

Each GPCCS unit was reading the mask from GPC0, which causes problems on boards where some GPCs are missing PPCs. Part of the fix for fdo#92761. Signed-off-by: Ben Skeggs

drm/nouveau/gr/gf100-: split out per-gpc address calculation macro

2015-11-25T05:31:21Z

There's a few places where we need to access a GPC register from ucode, but outside of the falcon's io address space. To do this we need to calculate the offset based on which GPC we're executing on. This used to be done manually, but we've since found a "base" offset that can be added by the hardware. To use this, an extra bit needs to be set in the register address, which is what this macro achieves. There should be no functional change from this commit. Signed-off-by: Ben Skeggs

drm/nouveau/bios: return actual size of the buffer retrieved via _ROM

2015-11-25T05:31:21Z

Fixes detection of a failed attempt at fetching the entire ROM image in one-shot (a violation of the spec, that works a lot of the time). Tested on a HP Zbook 15 G2. Signed-off-by: Ben Skeggs

drm/nouveau/instmem: protect instobj list with a spinlock

2015-11-25T05:31:21Z

No locking is required for the traversal of this list, as it only happens during suspend/resume where nothing else can be executing. Fixes some of the issues noticed during parallel piglit runs. Signed-off-by: Ben Skeggs
