[Qemu-devel] PCI support

[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

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.

[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.

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-boot.png
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!
