Subject: kernel for 405 w/ FPU available
Date: Wed, 11 Dec 2002 16:27:55 -0700 [thread overview]
Message-ID: <3DF7C9FB.C1BB9BA5@midrivers.com> (raw)
I've finished the initial work to support the IBM 405pm
[405 core, larger caches, FPU] and was wondering if anyone
wants it integrated into the _devel tree.
I worked out of the 2.4 _devel rsync tree (2.4.20-rc2) as I wasn't
able to get my bitkeeper snapshot to compile for walnut.
High level view of the changes:
config.in changes to set a cpu type of 405pm,
FPU unavailable exception, load_up_fpu(), giveup_fpu(),
additions to the ibm ethernet code to support the multiplexed
mal ints on the 405pm,
bits & pieces to tie it all together, and a hack or 2 which ought
to be reworked.
Missing:
no PCI, DMA or IDE support yet.
send me email if The Powers That Be want this stuff. It has been
stress tested with a mix of fpu tasks and handling a ping flood.
Mark
