Did you change anything for BLAST except for rev F support?
I enabled APIC mode for BLAST.

I've got probably is a rev B, it is dead now, But I captured some dump before it went dead, I still try to understand why it runs in PIC mode... Does LinuxBIOS need to program PIC or APIC, I don't LinuxBIOS was doing that.. Would it cause problem if leave PIC/APIC unprogrammed?

woops, had that swapped. Rev A has 87427, B has 4307.

it is SMSC SCH 4307, I ported some code for that serail, it works.

Good.
I can not get serial output from that MB, what is your superio on
the
MB?

It is not Blast, it is newer version of Broadcom board, it is
called
Explosion board.

BLAST?
That code in the tree should work.

I was working this Broadcom bcm 5785 based reference board with LinuxBIOS, I have a NIC interrupt related issue, the eth0 DHCP detection
always
fail,
so I can not get an IP address for that NIC. I did what Peter Stuge suggested to dump the /proc/interrupts. It turns out the Linux is using PIC
mode,
not APIC mode. (Linux report multiple CPUs, so I assume Linux took MP
Table
somewhat correctly)
I checked chipset setting, the APIC indeed is enabled. I don't
see
Linux
is doing anything for PIC or APIC, I assume Linux kernel will
correctly
initialize PIC or APIC depends on MP Table reporting. right?
If anybody has any idea on why Linux is running at PIC mode,
Please
let
me know. I will be very appreciated.
Thanks

For the RTC patch, it is porting for a SMSC SIO, I didn't see LinuxBIOS has this SIO porting. The part number is SCH--4703, I don't know how to contribute it to LinuxBIOS tree.
Ahh! It's new code, sorry, forgot that.
Please have a look at
http://linuxbios.org/Development_Guidelines to
learn most if not all you need to know to submit a patch.
Also, when submitting patches, please make sure they apply
cleanly
to the very latest revision of the tree.
The simplest way to do this is to always keep your own tree
updated
by running svn up now and then, or when you see a new revision announced on the list. After an update, there may be conflicts
that
need to be resolved manually by you if you have been working on
code
that was also changed in the new revision.
I haven't get the chance to take look at my NIC issue yet, I
will
certainly check the interrupt when I get the chance.
Feel free to ask the list if you run into trouble!
//Peter
