When using the nouveau driver, my screen freezes (and stays frozen) when it starts to more than a minimum amount of work. To fix this, I've been using the nvidia driver with the Preferred Mode set to Prefer Maximum Performance. It looks like equivalent settings in nouveau are NvClkMode and NvMemExec. However, I didn't see any documentation specifying the valid options for these settings? What are the valid options for NvClkMode? What are the valid options for NvMemExec? Thanks. Joseph D. Wagner

The only way I can get my nvidia card to work is by using the nvidia driver with these settings: Section "Device" Identifier "Videocard0" Driver "nvidia" Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefaultAC=0x1" EndSection Otherwise, whether I use the nouveau or nivida driver, it

...uld work on the majority of machines (if not all). In order to reclock, PFIFO must be paused. The first patch hooks up the corrent pausing method for NV50/NV84. Unfortunately, SUBDEV_CLOCK is initialised before ENFINE_FIFO, leading to a nullptr dereference when trying to reclock using config="NvClkMode=xx". Although "failure" on other cards is not as explicit, they do seem to stir up some registers in the PFIFO space as well. I am therefore led to believe the proper fix is initialising PFIFO earlier. However, although I can simply reorder some bits in device.h, I don't oversee...

There might be some callers of nouveau_clock_astate(), and they are from inetrrupt context. So we must ensure that this function can be atomic in that condition. This patch adds one parameter which is subsequently passed to nouveau_pstate_calc(). Therefore we can choose whether we want to wait for the pstate work's completion or not.

Hi, This is a try to have some simple DVFS (Dynamic Voltage and Frequency Scaling) support for GK20A. Instead of relying on other existing frequency scaling framework, we create a simple subdev in Nouveau for the same purpose. That's because we don't want to make the DVFS implementation for GK20A far more than enough in the beginning and hinder the implementation for dGPU in the future.
