2014-06-11drm/nouveau/i2c: introduce locking at a per-port levelBen Skeggs
There's also provisions to allow a pad to be locked with a specific routing, for an indefinite period of time. This will be used in future patches. The G94+ pad driver will now also power-down pads when not required. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-06-11drm/nouveau/i2c: balance port acquire/releaseBen Skeggs
This was a half-finished hack before, just enough to handle the shared aux/i2c pad thing on G94 and up. We got lucky with locking etc up until now, as this was (generally) all protected by the DRM mode_config lock. It's about to become a lot more likely to hit the races.

2014-06-10drm/nouveau/kms/nv04-nv40: fix pageflip events via special case.Mario Kleiner
Cards with nv04 display engine can't reliably use vblank counts and timestamps computed via drm_handle_vblank(), as the function gets invoked after sending the pageflip events. Fix this by defaulting to the old crtcid = -1 fallback path on <= NV-50 cards, and only using the precise path on NV-50 and later.

2014-06-10drm/nv50-/mc: fix kms pageflip events by reordering irq handling order.Mario Kleiner
Whenever a single nouveau_mc_intr() main gpu irq-handler invocation was responsible for calling both, the vblank-irq handler (display engine irq) and kms-pageflip completion handler (from fifo irq), the order of invocation was wrong. nouveau_finish_flip() was called before drm_handle_vblank() for the vblank of pageflip completion, so the emitted pageflip event contained stale vblank count and timestamp from previous vblank. This caused failure in userspace to timestamp properly. Reorder order of invocation of engine irq handlers: Put NVDEV_ENGINE_DISP always on top, and thereby before NVDEV_ENGINE_FIFO, so that drm_handle_vblank() gets called to update vblank timestamps and count before potential pageflip events make use of that information. This works on nv-50 and later, where kms-pageflip completion triggers an irq either after a separate vblank irq, or both pageflip and vblank trigger one common irq invocation, but never before vblank irqs. v2 (Ben): - removed mods for nv04-nv40, it doesn't help there anyway - this is considered a hack, and a better solution should be found Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Cc: <stable@vger.kernel.org> # 3.13+
2014-06-10drm/nouveau/disp/nv04-nv40: abort scanoutpos query on vga analog.Mario Kleiner
nv04_disp_scanoutpos() must abort to trigger simple timestamping fallback if vtotal/htotal regs return zero. This happens if the output isn't a digital output, but a vga analog output, as the regs don't get initialized in that case. Fixes timestamping failure on nv-40 and earlier with vga output.

2014-06-10drm/nouveau/therm/fan/tach: default to 2 pulses per revolutionMartin Peres
I spent some time this weekend trying to find in the vbios the number of pulses per revolutions in the vbios but couldn't find it. It would seem all my cards have 2 pulses per revolution so let's stick to that until further notice. Thermal table's id 0x48 may indicate this information but it would seem that changing the value results in the blob power or clock gating the RPM counter... We should ask NVIDIA about that, should be trivial-enough for them to answer. Signed-off-by: Martin Peres <martin.peres@free.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-06-10drm/nouveau/graph: enable when using external fwAlexandre Courbot
nvc0_graph_ctor() would only let the graphics engine be enabled if its oclass has a proper microcode linked to it. This prevents GR from being enabled at all on chips that rely exclusively on external firmware, even though such a use-case is valid. Relax the conditions enabling the GR engine to also include the case where an external firmware has also been loaded. Also switch to external firmware if the graph class has no microcode linked to it. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

Adapt the NVC0 BAR driver to make it able to support chips that do not expose a BAR3.
