2020-07-24drm/nouveau/nvfw: firmware structures should begin with nvfw_Timur Tabi1-4/+4
Rename all structures that are used directly by firmware to have a nvfw_ prefix. This makes it easier to identify structures that have a fixed, specific layout. A future patch will define several more such structures, so it's important to be consistent now. Signed-off-by: Timur Tabi <ttabi@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2020-01-15drm/nouveau/flcn/msgq: pass explicit message queue pointer to recv()Ben Skeggs1-2/+1

2020-01-15drm/nouveau/flcn/msgq: move handling of init message to subdevsBen Skeggs1-39/+18
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. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-01-15drm/nouveau/flcn/msgq: drop nvkm_msgqueue argument to functionsBen Skeggs1-26/+19

2020-01-15drm/nouveau/flcn/msgq: simplify msg_queue_pop() error handlingBen Skeggs1-18/+7
We always want at least requested size, make anything less a more direct error condition. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-01-15drm/nouveau/flcn/msgq: remove error handling for msg_queue_open(), it can't failBen Skeggs1-7/+2

2020-01-15drm/nouveau/flcn/qmgr: rename remaining nvkm_msgqueue bits to nvkm_falcon_qmgrBen Skeggs1-2/+2

2020-01-15drm/nouveau/flcn/qmgr: support syncronous command submission from common codeBen Skeggs1-3/+5
Functions implementing FW commands had to implement this themselves, let's move that to common code and plumb the return code from callbacks through. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-01-15drm/nouveau/flcn/qmgr: allow arbtrary priv + return code for callbacksBen Skeggs1-7/+8
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.

2020-01-15drm/nouveau/flcn/qmgr: move sequence tracking from nvkm_msgqueue to ↵Ben Skeggs1-4/+6

2020-01-15drm/nouveau/flcn/msgq: explicitly create message queue from subdevsBen Skeggs1-0/+39
Code to interface with LS firmwares is being moved to the subdevs where it belongs, rather than living in the common falcon code. This is an incremental step towards that goal. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-01-15drm/nouveau/flcn: split msgqueue into multiple piecesBen Skeggs1-0/+216
To make things clearer while modifying the interfaces, split msgqueue into Queue Manager, Command Queue, and Message Queue. There should be no code changes here, these will be done incrementally. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
