Subject: dcache_blast() bug?
Date: Mon, 04 Jun 2001 10:34:48 -0700	[thread overview]
Message-ID: <3B1BC6B8.C58758FA@palmchip.com> (raw)


Hi all,

I'm seeing some odd memory behavior around the time when blast_dcache()
is called, leading me to think that the method may be a little buggy. 
It appears that memory is being corrupted (consistently so) over the
course of flushing the dcache.  This happens to my command line argument
string - arcs_cmdline.  Before the blast_dcache() call, it is
"console=ttyS0 ramdisk_start=0x9fcf0000 load_ramdisk=1", and after the
call, the corrupted data is "ttyS0 ra0".  I take it this isn't supposed
to happen?  any ideas of why the writeback_invalidate_d cache operation
may be losing data?

thanks,
-ian
