System: NetBSD onyx.absd.org 4.0_STABLE NetBSD 4.0_STABLE (_ACPI_) #4: Sun Apr 20 17:33:56 BST 2008 root@iris.absd.org:/var/obj/i386/home/netbsd/4/sys/arch/i386/compile/_ACPI_ i386
Architecture: i386
Machine: i386
>Description:
When an ACPI enabled kernel is booted under qemu it cannot detect
the network or disk devices. Booting a kernel with ACPI disabled,
or running qemu with -no-acpi does not show the issue.
Its quite likely this is a qemu bug, but it could also be qemu
showing up an edge case in NetBSD's ACPI support.
Other devices, including the emulated CD drive appear to be
detected fine
>How-To-Repeat:
- Install qemu
- Download the latest i386 boot.iso from
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-daily/HEAD/.../i386/installation/cdrom/boot.iso
- Create a virtual disk 'qemu-img create -f qcow2 test.img 1G'
- Boot the ISO image 'qemu -hda test.img -cdrom boot.iso -boot d'
If you want to interrupt the boot to disable ACPI then you need to
hit space *extremely* quickly after the qemu window opens, as the
boot timer countdown runs much faster under qemu.

Log Message:
Apply fixes from jmcneill@ for PR port-i386/38729
(ACPI kernel booted under qemu cannot detect devices):
- make MP SCANPCI function for ACPI_SCANPCI and MPBIOS_SCANPCI
return a number of attached PCI busses
- if no valid PCI busses are attached in the MP SCANPCI function,
try to probe and attach pci0 at mainbus as well as kernels
with no SCANPCI options
"Feel free to check it in" from jmcneill@.
Tested in pkgsrc qemu-0.9.1 (both i386 and x86_64) on NetBSD/i386.
Note original jmcneill's patch was posted on March:
http://mail-index.NetBSD.org/port-i386/2009/03/24/msg001281.html
and I also applied it to amd64:
http://mail-index.NetBSD.org/port-i386/2009/03/24/msg001283.html
but x86 MP attach functions have been reorganized by dyoung@ on April:
http://mail-index.NetBSD.org/source-changes/2009/04/17/msg219992.html
so I've modified the original patches to adapt the changes.
(mpacpi_scan_pci() and mpbios_scan_pci() have been merged into
common mp_pci_scan() in new arch/x86/x86/mp.c)
For netbsd-5 and netbsd-5-0 branches, the original patches should be
applied cleanly, and they have been tested by abs@ on a selection of
i386 boxes and in qemu.
