jchandra 2010-09-08 16:34:08 UTC FreeBSD src repository Modified files: sys/mips/rmi fmn.c msgring.h sys/mips/rmi/dev/xlr rge.c Log: SVN rev 212321 on 2010-09-08 16:34:08Z by jchandra Clean up fast message ring code for XLR. Fix message ring send path: - define msgrng_access_enable() which disables local interrupts and enables message ring access. Also define msgrng_restore() which restores interrupts - remove all other msgrng enable/disable macros, no need of critical_enter and other locking here. - message_send() fixup: re-read status until pending bit clears - message_send_retry() fixup: retry only few times with interrupts disabled - Fix up message_send/message_send_retry callers - call msgrng_access_enable() and msgrng_restore() correctly so that interrupts are not disabled for long. - removed unused and obsolete code from sys/mips/rmi/msgring.h - some style fixes - more later rge.c (XLR GMAC driver): - updated for the message ring changes - remove unused message_send_block() - retry on credit failure, this is not a permanent failure when credits are configured correctly. Add panic if credits are not available to send for a long time.
