commit c4f9c4c2b3f1831e932e04db992cf6fe92c2a95a upstream. It's needed for 3 pipe support as well as just regular functionality (e.g. DisplayPort).

drm/radeon/kms: make an aux failure debug only

commit 091264f0bc12419560ac64fcef4567809d611658 upstream. Can happen when there is no DP panel attached, confusing users. Make it debug only. Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/nouveau: initialize chan->fence.lock before use

2011-11-21T22:35:20+00:00

commit 5e60ee780e792efe6dce97eceb110b1d30bab850 upstream. Fence lock needs to be initialized before any call to nouveau_channel_put because it calls nouveau_channel_idle->nouveau_fence_update which uses fence lock. BUG: spinlock bad magic on CPU#0, test/24134 lock: ffff88019f90dba8, .magic: 00000000, .owner: /-1, .owner_cpu: 0 Pid: 24134, comm: test Not tainted 3.0.0-nv+ #800 Call Trace: spin_bug+0x9c/0xa3 do_raw_spin_lock+0x29/0x13c _raw_spin_lock+0x1e/0x22 nouveau_fence_update+0x2d/0xf1 nouveau_channel_idle+0x22/0xa0 nouveau_channel_put_unlocked+0x84/0x1bd nouveau_channel_put+0x20/0x24 nouveau_channel_alloc+0x4ec/0x585 nouveau_ioctl_fifo_alloc+0x50/0x130 drm_ioctl+0x289/0x361 do_vfs_ioctl+0x4dd/0x52c sys_ioctl+0x42/0x65 system_call_fastpath+0x16/0x1b It's easily triggerable from userspace.

drm/i915: Fix object refcount leak on mmappable size limit error path.

2011-11-21T22:35:19+00:00

commit 14660ccd599dc7bd6ecef17408bd76dc853f9b77 upstream. I've been seeing memory leaks on my system in the form of large (300-400MB) GEM objects created by now-dead processes laying around clogging up memory. I usually notice when it gets to about 1.2GB of them. Hopefully this clears up the issue, but I just found this bug by inspection.

drm/radeon/kms: set HPD polarity in hpd_init()

2011-11-11T17:44:09+00:00

commit 64912e997f0fe13512e4c7b90e4f7c11cb922ab5 upstream. Polarity needs to be set accordingly to connector status (connected or disconnected). Set it up in hpd_init() so first hotplug works reliably no matter what is the initial set of connector. hpd_init() also covers resume so HPD will work correctly after resume as well.

drm/radeon/kms: add MSI module parameter

2011-11-11T17:44:08+00:00

commit a18cee15ed4c8b6a35f96b7b26a46bac32e04bd9 upstream. Allow the user to override whether MSIs are enabled or not on supported ASICs. MSIs are disabled by default on IGP chips as they tend not to work. However certain IGP chips only seem to work with MSIs enabled. I suspect this is a chipset or bios issue, but I'm not sure what the proper fix is. This will at least make diagnosing and working around the problem much easier.
