Subject: MIPS 4KEc with 2.6.15
Date: Mon, 07 Jan 2008 09:39:29 +0900 [thread overview]
Message-ID: <478174C1.2090708@lundman.net> (raw)
Hello list,
I have an embedded device running 2.6.15 kernel on a MIPS 4KEc 300MHz
CPU. It was configured for Sigma's tango2 board, which I know nothing
about, so I picked a mips-board by random, "atlas", and found I can
produce working kernel module compiles.
However, when I compiled FUSE kernel module, it behaves erratically in a
way making the FUSE developer think I may have come across the cache
coherency bug in arm and mips, fixed sometime around 2.6.17.
Since I can not change the kernel that is running, I was looking for
alternate solutions. FUSE itself has a work around, that calls
flush_cache_page(), but I found that mips-board atlas does not have this
defined:
fuse: Unknown symbol flush_cache_page
Should I try other mips-boards that may have this function call defined?
Do I have other ways to avoid the cache coherence bug?
The /proc/ksyms is gone, so I do not think I am able to check what
symbols their kernel has.
Lund
