would cxgbe be a good example of using firmware files?

ddi_ufm is the way, I believe

I'm not sure how you choose among the drivers using it

I'd guess that and nvme are the most heavily used

i don't think that is for reading a (volatile, not NVM) file to write to the device during attach or such

i guess technically it'd be more of an opaque blob

for E810 (ice) it apparently requires what intel calls a 'dynamic device personalization (DDP)' file that is loaded from the OS during 'initialization' (i.e. attach)... on fbsd, this is apparently done as a separate module (ice_ddp), but based on the readme with it, it seems like the file is redistributable, so instead of trying to wrap it in a module or convert it to a giant .h file, i thoguht there's a way

to read it from the filesystem

(apparently the DDP is required for things like RSS)

and the card enters a 'safe mode' without it

(it seems like most of the other bits in it wouldn't be as useful at this time)

(this is also unlike i40e where the card apparently includes a default configuration in it's NVM)

jbk: Assuming this is a file that basically needs to be read and installed in the hw every boot then yeah, the firmload(9F) bits are what I'd use. The cxgbe examples are fine.

ok
