Subject: Guidelines to make RT patch for driver
Date: Fri, 30 Mar 2012 19:22:23 +0300 [thread overview]
Message-ID: <4F75DDBF.7050204@softerra.com> (raw)
Hello,
on my AT91SAM9263 based board RT patched kernel works great! Thanks to
all involved. But when ethernet is in use - latency, measured by
cyclictest, reach 7000000 and beyond.
The ethernet driver for this processor is macb.c. (in 3.2 it is in
drivers/net/ethernet/cadence, in 3.0 it is in drivers/net/).
I'm ready to find out how to RT-patch it and of course share the
resulted patch, but I need some starting point for patching drivers
besides general RT-stuff. I've noticed that some network drivers
patched in one way and others a in another. Maybe some discussion
existed which I didn't found. So any help would be greatly appreciated.
Thanks in advance,
Mikhail
