Could you elaborate on what do you think is needed? I have some of patches to firmware loader and wondering if we should coordinate out efforts. I have
1. convert from using a timer to wait_for_comletion_timeout which simplifies logic 2. tightening of state transition rules and removing possible memory leak (very unlikely) 3. converting firmware_priv to fw_class_dev to simplify memory management. 4. removing request_firmware_nowait as noone seems to be using it - and I doubt one would ever want to request firmware from an interrupt. 5. Creating firmware class in a separate thread to work around selinux (with prism54 firmware is loaded when interface is configured and thus firware loader runs in context of /sbin/ip which may not have access to sysfs. Having separate thread will ensure that firmware loader runs in kernel context).
And I was thinking about caching firmware (siomething like if you do "echo 2 > /sys/class/firmware/blah/loading" instead of 0 it will keep a copy of the firmware in memory. One could see all firmwares in /sys/class/firmware/loaded/<xxx> and by erase cached firmware by echoing 0 into it).
What do you think?
