2014-12-01drm/g84-/fifo: ack non-stall interrupt before handling itBen Skeggs3-4/+4
Closes a very unlikely race that can occur if another NonStallInterrupt method passes between checking fences and acking the previous interrupt. With this change, the interrupt will re-fire under such conditions. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

The binary driver modifies the default context to have this value, rather than 0x3d0040, *after* it's filled the buffer with the usual golden data. We don't really have anything in place to locate the correct offset to do these type of modifications outside of the generation function, so this will have to do.

2014-10-02drm/nouveau: make sure display hardware is reinitialised on runtime resumelinux-3.17Ben Skeggs3-53/+26
Linus commit 05c63c2ff23a80b654d6c088ac3ba21628db0173 modified the runtime suspend/resume paths to skip over display-related tasks to avoid locking issues on resume. Unfortunately, this resulted in the display hardware being left in a partially initialised state, preventing subsequent modesets from completing. This commit unifies the (many) suspend/resume paths, bringing back display (and fbcon) handling in the runtime paths. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-10-02drm/nouveau: punt fbcon resume out to a workqueueBen Skeggs2-6/+18
Preparation for some runtime pm fixes. Currently we skip over fbcon suspend/resume in the runtime path, which causes issues on resume if fbcon tries to write to the framebuffer before the BAR subdev has been resumed to restore the BAR1 VM setup. As we might be woken up via a sysfs connector, we are unable to call fb_set_suspend() in the resume path as it could make its way down to a modeset and cause all sorts of locking hilarity. To solve this, we'll just delay the fbcon resume to a workqueue. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-10-02drm/nouveau: fix regression on original nv50 boardBen Skeggs1-1/+6
Xorg (and any non-DRM client really) doesn't have permission to directly touch VRAM on nv50 and up, which the fence code prior to g84 depends on. It's less invasive to temporarily grant it premission to do so, as it previously did, than it is to rework fencenv50 to use the VM. That will come later on.

2014-09-30drm/nouveau: nv84+: fix fence context seqno'sMaarten Lankhorst1-2/+1
This fixes a regression introduced by "drm/nouveau: rework to new fence interface" (commit 29ba89b2371d466). The fence sequence should not be reset after creation, the old value is used instead. 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 <ted@tedp.id.au> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> Tested-by: Ted Percival <ted@tedp.id.au> Acked-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
