Disclaimer: I am well aware that it is the complete wild west right now
as far as accelerators go and that every vendor (that I happen to work
for, just not in the same group as Scott) is just seeking to get their
drivers included upstream and hopefully for good reasons.
From a cursory look however, it sounds like there could be a little
better re-utilization of standards, standard framework and interfaces:
- about 2/3 of your sysfs attributes should incline you to implement a
HWMON device, not a complicated one, but anything that indicates
current, power, temperature, alerts etc. should be considered
- cannot the firmware loading be supported over remoteproc somehow?
- could not the TTY interface be using virtio or an existing UART?
- what is the format of the message over BAR2 that you expose in patch 13?
Is there a reference user-space implementation that you can link to this
patch submission in case people are curious?
Thanks
