Subject: [PATCH B 0/3] tidspbridge: don't flood the mailbox
Date: Wed, 18 Mar 2009 03:26:42 +0200 [thread overview]
Message-ID: <1237339605-20697-1-git-send-email-felipe.contreras@gmail.com> (raw)
This patch series is meant to be applied on top of the previous one (A) and
fixes a very nasty problem that causes interrupts to be constantly dropped
since the mailbox is full most of the time. The details are explained in patch
0001.
Flooding the mailbox causes reliability issues (messages lost) and performance
issues (busy looping waiting for a slot in the mailbox).
Felipe Contreras (3):
tidspbridge: don't flood the mailbox on MemUnMap
tidspbridge: cleanup and remove HW_MMU_TLBFlushAll
tidspbridge: decreate timeout to a saner value
