2013-02-20drm/nv17/fence: split from nv10 codeBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nv84-/fence: abstract class emit/sync functions to virt+sequenceBen Skeggs
Now can be used to operate on any buffer mapped into the GPU virtual address and not just the main inter-channel sync buffer. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nv84/fence: access fences with full virtual address, not offsetBen Skeggs
Allows most of the code to be shared between nv84/nvc0 implementations, and paves the way for doing emit/sync on non-VRAM buffers (multi-gpu, dma-buf). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/gpio/nve0: interrupt regs moved on kepler apparentlyBen Skeggs

2013-02-20drm/nouveau/fifo/nv84: support user event triggerBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/fifo/nvc0-: use interrupt 31 as an event triggerBen Skeggs
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 Skeggs
This removes the nastiness with the interactions between display and software engines when handling vblank semaphore release interrupts. Now, all the semantics are handled in one place (sw) \o/. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/disp/nv04: implement a base display object classBen Skeggs
Will be used for upcoming vblank event interfaces. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/fifo/nvc0: improve interrupt handler somewhatBen Skeggs
Logs extra info for interrupts that have a sub-status register, and handles the "special" ack from INTR bit 31. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-02-20drm/nv40/therm: reset temperature sensor on initMarcin Slusarz
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/therm: turn on fan only when threshold hit in positive directionMarcin Slusarz

2013-02-20drm/nouveau: remove unnecessary null pointer check from nouveau_fence_newCong Ding
the variable chan is dereferenced in line 190, so it is no reason to check null again in line 198. Signed-off-by: Cong Ding <dinggnu@gmail.com> Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-02-20drm/nouveau/fan: fix selection of fan speed when fan->get returns an errorMarcin Slusarz
fan->get returns int, but we write it to unsigned variable, and then check whether it's >= 0 (it always is) Found by smatch: drivers/gpu/drm/nouveau/core/subdev/therm/fan.c:61 nouveau_fan_update() warn: always true condition '(duty >= 0) => (0-u32max >= 0)' Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-02-20drm/nouveau/fan: handle the cases where we are outside of the linear zoneMartin Peres
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 Peres
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: set legacy bios data before parsing the structureEmil Velikov
Commit 767baf82 drm/nouveau: remove some more unnecessary legacy bios code has introduced a regression my misplacing the code that sets the major/chip versions, which are used whist parsing the bmp/bit structure in vbios Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/therm: don't try pwm/toggle control if GPIO_FAN is inputBen Skeggs
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/hwmon: add missing alarm thresholdsMartin Peres

2013-02-20drm/nouveau/therm: implement support for temperature alarmsMartin Peres
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>
