* drm/nv84-/fence: prepare for emit/sync support of sysram sequencesBen Skeggs2013-02-20
| | | | Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/fence: make internal hooks part of the contextBen Skeggs2013-02-20
| | | | | | | A step towards being able to provide fences from other engines not connected to PFIFO. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv17/fence: split from nv10 codeBen Skeggs2013-02-20
| | | | Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv84-/fence: abstract class emit/sync functions to virt+sequenceBen Skeggs2013-02-20
| | | | | | | 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>
* drm/nv84/fence: access fences with full virtual address, not offsetBen Skeggs2013-02-20
| | | | | | | | 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>

* drm/nouveau/fifo/nvc0-: use interrupt 31 as an event triggerBen Skeggs2013-02-20
| | | | | | | 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>
* drm/nouveau/disp: port vblank handling to event interfaceBen Skeggs2013-02-20
| | | | | | | | | 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>
* drm/nouveau/disp/nv04: implement a base display object classBen Skeggs2013-02-20
| | | | | | Will be used for upcoming vblank event interfaces. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau/fifo/nvc0: improve interrupt handler somewhatBen Skeggs2013-02-20
| | | | | | | 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>

* drm/nv40/therm: reset temperature sensor on initMarcin Slusarz2013-02-20
| | | | | | | | | | | | 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.

* drm/nouveau/fan: fix selection of fan speed when fan->get returns an errorMarcin Slusarz2013-02-20
| | | | | | | | | | | 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>

* drm/nouveau/fan: handle the cases where we are outside of the linear zoneMartin Peres2013-02-20
| | | | | | | | | | | | | 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.

* drm/nouveau/therm: force a minimum hysteresis on temperature alarm thresholdsMartin Peres2013-02-20
| | | | | | | | | | | This should avoid the situation where a user gets its kernel logs flooded when temperature oscillates around a threshold with 0°C hysteresis.
