drm/nouveau/pmu/gm200-: avoid touching PMU outside of DEVINIT/PREOS/ACR

2021-11-12T22:46:03Z

There have been reports of the WFI timing out on some boards, and a patch was proposed to just remove it. This stuff is rather fragile, and I believe the WFI might be needed with our FW prior to GM200. However, we probably should not be touching PMU during init on GPUs where we depend on NVIDIA FW, outside of limited circumstances, so this should be a somewhat safer change that achieves the desired result.

drm/nouveau/subdev: store full subdev name in struct

2021-02-11T00:14:26Z

Much easier to store this to avoid having to reconstruct a string for a specific subdev, taking into account whether it's instanced or not. Signed-off-by: Ben Skeggs Reviewed-by: Lyude Paul

drm/nouveau/pmu/gm20x: don't pretend we support loading with our custom FW

2020-07-24T08:50:48Z

It technically loads, and runs, but is ultimately pointless outside of a very narrow window (fanless systems where one wants to attempt using the, broken for a lot of gm20x, memory reclocking code). It's also potentially dangerous to override the VBIOS-provided "Pre-OS" PMU, which would be responsible for fan control otherwise. Signed-off-by: Ben Skeggs

drm/nouveau/acr: store a mask of LS falcons the controlling LSFW can bootstrap

2020-07-24T08:50:48Z

This will prevent some pain with broken firmware trees, as under some circumstances the HSFW can fail and leave the GPU in a state we don't know how to recover from. Signed-off-by: Ben Skeggs
