[RFC PATCH 0/4] Add ocode late binding support for CRI

[RFC PATCH 0/4] Add ocode late binding support for CRI

[Badal Nilawar]

Ocode is the OOBMSM telemetry/manageability firmware, and on CRI it is
loaded through late binding flow.

Dependancy: There is dependancy on mei side of patches to support ocode late binding,
	    which are not upstreamed yet. Hence, this patch is marked as RFC.

Badal Nilawar (4):
  drm/xe/xe_late_bind_fw: Refactor pm flow
  drm/xe/xe_late_bind_fw: Add support to load Ocode firmware on CRI
  drm/xe/xe_late_bind_fw: Track firmware load status
  drm/xe/xe_late_bind_fw: Enable late binding support for CRI

since it is now static, you can perhaps remove entirely the
prefix 'xe_late_bind_' to make it shorter.

I prefer without it but I don't believe it hurts to keep it. Up to you:

I think it'd better to keep an empty line before the "out" label.

Are we expecting different ocodes for each PCI id? if not, we could name 
this like the other fw binaries as <platform>_ocode.bin (e.g., 
cri_ocode.bin)

Why is this check being removed? is MEI/CSC now going to accept bigger 
payloads?

This will now automatically look for ocode for bmg as well. not an 
issue, but potentially noise in dmesg. Maybe we could change 
has_late_bind to be a mask of supported fw types? that way we can set it 
to BIT(XE_LB_FW_FAN_CONTROL) on BMG and BIT(XE_LB_FW_OCODE) on CRI and 
skip the FW type if not set in the mask. Not a blocker.

[RFC PATCH 3/4] drm/xe/xe_late_bind_fw: Track firmware load status

[Badal Nilawar]

In CRI, Intel PMT depends on the ocode runtime status. Track the
late-binding firmware load status and expose an API, for xe_vsec driver,
to query it.

I think it would be better to send this patch with the series that adds 
the xe_vsec changes, otherwise we have no idea from a review POV on how 
you plan to use the new exposed API.

I am not convinced that this is the correct place for this. We might 
have cases in the future where we want to do a flush without clearing 
the state (e.g. before a reset).
Also, in the suspend scenario you're already adding xe_late_bind_fw_stop.

This returns a value from xe_late_bind_fw_status, so might be worth just 
saying that.
also, you haven't defined the enum as starting from 0.
