All,

The following message thread is present in the Linux-Mips archives regarding
the use of gettimeofday on Broadcom MIPS systems.
http://www.linux-mips.org/archives/linux-mips/2006-01/msg00144.html  The
message thread specifically addresses the Dual-core Broadcom 1250 system,
and the kernel version mentioned in the message thread is 2.6.12.  I looked
at the files mentioned in the message thread in the 2.6.17 kernel, and the
changes suggested for arch/mips/dec/time.c were present in 2.6.17.  However,
the subsequent patches suggested in the message thread were not present in
the version of the 2.6.17 kernel I checked.  We'd like to ask if the patches
suggested in the message thread have been observed to influence performance
numbers obtained by other Linux system developers for Quad-core Broadcom
1480 systems?  If so, do the Linux-Mips developers suggest that we apply the
patches suggested in the message thread for our Broadcom 1480 MIPS specific
Linux 2.6.17 system implementation?

Thanks,

Gary
