Re: [Qemu-devel] kernel-kqemu and linux

2006-03-20 Thread Kevin F. Quinn

Sorry, still fails at the same place.  It recognises the APIC:

...
Found and enabled local APIC!
mapped APIC to d000 (fee0)
...

I noticed that before the 'kernel BUG' message I got a warning that
scrolled off the screen; so I halted qemu and captured it piece by
piece:

...
hda: cache flushes not supported
 hda:Badness in blk_remove_plug at block/ll_rw_blk.c:1436
 xx blk_remove_plug+0x69/0x70
 xx ide_do_request+0x3c2/0x3f0
 xx do_ide_request+0x24/0x30
 xx generic_unplug_device+0x10/0x20
 xx block_sync_page+0x3a/0x50
...
 xx kernel_thread_helper+0x5/0xc
 hda1 hda2 hda3
[ cut here ]
kernel BUG at mm/swap.c:215!
... then as before (I can transcribe the whole trace if you want).


The warning is the following code:

int blk_remove_plug(request_queue_t *q)
{
WARN_ON(!irqs_disabled())

"Badness in" comes from the WARN_ON macro.  So it appears that linux
expects the irqs to have been disabled, which they are in the normal
emulation but not in the virtualised kernel mode.


Without -kernel-kqemu I don't get the warning (or the BUG):

...
hda: cache flushes not supported
 hda1 hda2 hda3
hdc: ATAPI 4X CD-ROM drive, 512kB Cache

and it boots up & works fine.

Kev.

If it works then APIC usage will become the default on i386...



I'm afraid that makes no difference at all here..
PIII-M linux host and both 2.4 compiled for i386 and 2.6 compiled for PII linux 
guests

[Qemu-devel] kernel-kqemu and linux

Hi.
