hardware support

[Littlefield, Tyler]

hello all:
I had a question. I get an address mmio error when  I try to boot my 
debian box, along with this: INIT_I2C_LONG_IF
I'm curious of something. I have an 8-core AMD zambesi, is there support 
for this yet? I also have channel interleaving turned on (we can't 
really get it off), is this also something Linux would have issues with?

Dear Mr. /Ms. 
  Which  release of the kernel support the intel dp965 mainboard?
Best wishes to you!

We have had some problems bringing up SLES10/Xen on DL360 box (dual
processor). The Compaq boxes have this notion of "auto" mode for
MPS/APIC to deal with buggy OSes and under this setting (which is the
default setting), vanilla Linux (2.6.16) comes up on this box in UP mode
since it finds the local APIC disabled in bios. However, the xen based
kernel tries to come up MP and fails in a non-intuitive way by  hitting
a BUG in the hypervisor code. Following is the stack trace of the xen
based kernel:

[<ff10f8d6>] alloc_vcpu+0x36/0x120
  [<ff1518c0>] smp_prepare_cpus+0x460/0xd30
  [<ff132fcd>] intel_p6_mcheck_init+0xbd/0xe0
  [<ff1555b4>] get_mtrr_state+0xf4/0x110
  [<ff1508f1>] __start_xen+0x5d1/0x9e0
  [<ff123270>] new_tlbflush_clock_period+0x0/0x90
  [<ff10015a>] start_paging+0x52/0x54
  CPU0 FATAL TRAP 6 (invalid opcode), ERROR_CODE 0000, IN INTERRUPT
CONTEXT.
  System shutting down--need manual reset.

As opposed to the vanilla linux kernel (that fails to see the local
apic), xen sees the local apic (incorrectly) and fails to bring up the
secondary CPUs and finally takes the FATAL TRAP as described in the
trace above.

If however, the bios setting is changed to Full APIC mode, both the
vanilla linux kernel and the xen based kernel boot correctly. I wanted
to know if others have seen similar problems. Also, is somebody looking
at addressing  these kinds of issues?

Regards,

K. Y

Noone else has reported this particular issue. We are interested in 
fixing this kind of thing. It'd be interesting to know where the native 
Linux boot decides to stay uniprocessor. Could you send dmesg output 
from booting native Linux on this system in "auto" mode?

I'm hung up at building a Xen Linux kernel with, really, any hardware
support. I'm using the Xen source package pulled from the Xen home page,
which pulls 2.6.10 from kernel.org, and when I do a make menuconfig
ARCH=xen, I simply don't see any of the hardware I'm after listed. No
3c509, no radeon, no e100, nada. My reading of the Xen docs suggest I
should be able to build whatever hardware support I need into the Xen0
kernel- is this the proper method for providing drivers, or am I missing
the point completely?

It sounds like you haven't enabled driver domain support.  If you want to run 
a kernel in dom0, you'll need support for physical device access and dom0 ops 
compiled in.

The options are in the Xen config menu.  You may find it helpful to start from 
the dom0 default config (somewhere under arch/xen, I can't remember exactly 
right now - copy it to linux/.config before running menuconfig).

Cheers,
Mark

I am getting a SGI Challenge L with r4400 processors and would like to know 
the status of a linux port that will run on it????

None exists.  The systems which are supported are listed in the FAQ.
