2010-12-08drm/nv04-nv40: Give "gpuobj->cinst" the same meaning as on nv50.Francisco Jerez1-2/+2
No functional changes, just simplify some code paths a bit. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-12-03drm/nv50: initial work to allow multiple evo channelsBen Skeggs1-1/+1

2010-11-18drm/nouveau: Avoid lock dependency between ramht and ramin spinlocks.Francisco Jerez1-27/+44
The ramht code called some gpuobj functions with the HARDIRQ-safe RAMHT spinlock held, this could potentially lead to a dead lock because ramin_lock is HARDIRQ-unsafe. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-09-24drm/nouveau: Don't remove ramht entries from the neighboring channels.Francisco Jerez1-0/+18

2010-09-24drm/nouveau: protect ramht_find() from oopsing if on channel without ramhtBen Skeggs1-0/+3
This doesn't actually happen now, but there's a test case for an earlier kernel where a GPU error is signalled on one of nv50's fake channels, and the ramht lookup by the IRQ handler triggered an oops. This adds a check for RAMHT's existance on a channel before looking up an object handle. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-09-24drm/nouveau: add spinlock around ramht modificationsBen Skeggs1-20/+56
