[Qemu-devel] PCI support

[Qemu-devel] PCI support

[Fabrice Bellard]

Hi,

PCI support is now in the QEMU CVS. It is experimental so it is not 
enabled by default (use the runtime option '-pci'). There is support for 
an i440FX bridge, PIIX3 ISA bridge, PCI IDE controller (without DMA) and 
NE2000 PCI card. I tested it succesfully with a Linux 2.4.21 kernel.

I still have to add a correct IRQ allocation, PowerPC support and a 
dummy VGA PCI board.

Fabrice.

[Qemu-devel] PCI support

[Hetz Ben Hamo]

Hi,

It seems that few minutes ago, Fabrice has commited:

* Script to convert VMWare images to raw images
* PCI Support
* NE2K PCI card...

And I was wondering, is there a chance that QEMU will let a user use an 
UNUSED PCI card which is inside the host machine? (example - graphics 
card, network analyzer, etc..)

Also, not to nitpick, but why PIIX3 and not PIIX4? documentation problem?

Thanks,
Hetz

I've just done some quick testing of the new PCI bus on a Win98 guest.
Win98 didn't see the PCI bus at first, but running the Add New Hardware
wizard and getting it to detect new non-PNP hardware detected the PCI
bus. After installing the appropriate drivers (and going through several
reboots) it has detected the ISA bridge, IDE controller and NE2k.
However, Windows gives a warning about the NE2k at boot and disables it
- it shows up in the device manager with the (!) icon attached to it.
I've put up a couple of screenshots:

http://gir.eclinic.com.au/~lsd/qemu/win98/win98-ne2k-deviceman.png

Let me know if there's any more info that I can provide. I also tried
booting a Win2k system, but it failed with an INACCESSIBLE_BOOT_DEVICE
error (common when trying to transplant a Win2k system in to a new PC),
so I might try to do a fresh Win2k install instead.

Thanks

Fabrice!

it is almost unbelievable, how fast you are :-)

I tested two cases:

- booting Solaris 10

  It failed the last time without PCI support with this:

  http://tmp.janik.cz/QEMU/Solaris-10-x86-boot.png

  It still doesn't continue booting, but Boot path has been changed

  http://tmp.janik.cz/QEMU/Solaris-10-x86-boot-with-pci.png

  It is now /pci@0,0/pci-ide@3/ide@1/sd@0,0:a

  Solaris detection find both PCI Ethernet card and IDE. It is the same
  with Solaris 9.

- GRUB boot floppy with stage2.netboot
  (http://tmp.janik.cz/QEMU/floppy.img)

  In one project I'm working on, we use this image to boot the systems that
  do not support PXE natively in BIOS. It is a simple GRUB floppy with
  stage2.netboot (supporting many types of network cards). The GRUB config
  file contains entries like:

  title xAPOSTclient
    dhcp
    root (nd)
    kernel (nd)/9.0/linux install=nfs://10.7.7.104/install/9.0/CD1 autoyast=nfs://10.7.7.104/install/9.0/xAPOSTclient.xml textmode=1
    initrd (nd)/9.0/initrd

  The card inside vmware is detected as

  http://tmp.janik.cz/QEMU/GRUB-vmware.png

  But in QEMU the detection seems to not work:

  http://tmp.janik.cz/QEMU/GRUB-qemu.png

  It detected RTL8139 (which is IMHO the default in GRUB when nothing
  detected properly).

Keep up the good work!

hi.

a little something about the vmware conversion script:
it won't work with files that excede a certain size. i tried it with a 3.7G 
image, which was apparently too large for the c++ open() function to handle.
[using gentoo linux, kernel 2.6.6, gcc 3.3.2-r5 (20031218), propolice-3.3-7]

i don't know of a way to get out of this problem.
do you?

greets,
Rudi

Have you used -pci command line option? What does it print?

Failure is not an option. It comes bundled with your Microsoft product.
