2013-02-20drm/nouveau/fifo/nvc0-: use interrupt 31 as an event triggerBen Skeggs4-3/+56
Generated if you try and use fifo method 0x20 on any subchannel, appears that it can be safely masked off without stalling the whole GPU. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/disp: port vblank handling to event interfaceBen Skeggs19-216/+226

2013-02-20drm/nv40/therm: reset temperature sensor on initMarcin Slusarz1-1/+11
Current uninitialized sensor detection does not work for me on nv4b and sensor returns crazy values (>190°C). It stabilises later, but it's too late - therm code shutdowns the machine... Let's just reset it on init. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Acked-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-02-20drm/nouveau/fan: handle the cases where we are outside of the linear zoneMartin Peres1-0/+7
This fixes a bug where, when temperature is outside of the linear range, fan pwm would be outside of the allowed range ([0, 100]) and could get negative in some cases. It seems like a regression that happened when we re-worked the fan management logic before merging.

2013-02-20drm/nouveau/therm: force a minimum hysteresis on temperature alarm thresholdsMartin Peres1-0/+7
This should avoid the situation where a user gets its kernel logs flooded when temperature oscillates around a threshold with 0°C hysteresis.

2013-02-20drm/nouveau/therm: don't try pwm/toggle control if GPIO_FAN is inputBen Skeggs2-7/+23
My GTX660 has the GPIO_FAN function, but it's configured in input-mode; presumably to monitor the frequency set by an I2C fan controller? Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-02-20drm/nouveau/therm: implement support for temperature alarmsMartin Peres9-1/+366
For now, we only boost the fan speed to the maximum and auto-mode when hitting the FAN_BOOST threshold and halt the computer when it reaches the shutdown temperature. The downclock and critical thresholds do nothing. On nv43:50 and nva3+, temperature is polled because of the limited hardware. I'll improve the nva3+ situation by implementing alarm management in PDAEMON whenever I can but polling once every second shouldn't be such a problem. v2 (Ben Skeggs): - rebased v3: fixed false-detections and threshold reprogrammation handling on nv50:nvc0 Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>

2013-02-20drm/nouveau/pbus: add a PBUS subdev that hands IRQs to the right subdevsMartin Peres21-4/+517
We are going to use PTHERM's IRQs for thermal monitoring but we need to route them first. On nv31-50, PBUS's IRQ line is shared with GPIOs IRQs. It seems like nv10-31 GPIO interruptions aren't well handled. I kept the original behaviour but it is wrong and may lead to an IRQ storm. Since we enable all PBUS IRQs, we need a way to avoid being stormed if we don't handle them. The solution I used was to mask the IRQs that have not been handled. This will also print one message in the logs to let us know. v2: drop the shared intr handler because of was racy v3: style fixes v4: drop a useless construct in the chipset-dependent INTR v5: add BUS to the disable mask v6 (Ben Skeggs): - general tidy to match the rest of the driver's style - nva3->nvc0, nva3 can be serviced just fine with nv50.c, rnndb even notes that the THERM_ALARM bit got left in the hw until fermi anyway.. so, it's not going to conflict - removed the peephole and user stuff, for the moment.. will handle them later if we find a good reason to actually care.. - limited INTR_EN to just what we can handle for now, mostly to prevent spam of unknown status bits (seen on at least nv4x) Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>
2013-02-20drm/nouveau/therm: implement automatic fan managementMartin Peres4-40/+139
v2: improved design but drops safety monitoring (to be in a later patch) v3: fix locking and mode management v4: gently fallback to the no-control mode when temperature cannot be got and use kernel-provided min/max macros v5 (Ben Skeggs): - rebased on my previous patches v6: fix hysterisis management in trip-based auto fan management This commit also forbids access to fan management to nvc0+ chipsets as fan management is already taken care of my PDAEMON's default fw.
