drm/nouveau/flcn/msgq: move handling of init message to subdevs · d114a139

Ben Skeggs authored Jan 15, 2020

When the PMU/SEC2 LS FWs have booted, they'll send a message to the host
with various information, including the configuration of message/command
queues that are available.

Move the handling for this to the relevant subdevs.

drm/nouveau/flcn/qmgr: allow arbtrary priv + return code for callbacks · c80157a2

Ben Skeggs authored Jan 15, 2020

Code to interface with LS firmwares is being moved to the subdevs where it
belongs, rather than living in the common falcon code.

Arbitrary private data passed to callbacks is to allow for something other
than struct nvkm_msgqueue to be passed into the callback (like the pointer
to the subdev itself, for example), and the return code will be used where
we'd like to detect failure from synchronous messages.
