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: -

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: -

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: -

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: -

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:

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:

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. Tested-by:

This should avoid the situation where a user gets its kernel logs flooded when temperature oscillates around a threshold with 0°C hysteresis. This patch is just meant to fix broken vbios (as reported on a nv4e on sysfs hwmon interface. Signed-off-by:
