Hi edk2 members

               I have a question for your help.
               I want to enable qemu+kvm+ovmf to boot up windows xp, then ovmf support winxp starting-up?
               qemu command:
               qemu-system-x86_64 -hda winxp.img -boot c -enable-kvm -cpu host -bios ./OVMF.fd -m 512 -vga cirrus -net nic,model=rtl8139 -net user -usbdevice tablet -localtime
               Then if ovmf support, could you provide me the way to compile the OVMF.fd?

Thanks,
Junhao

To my understanding, the first Windows "family" with any kind of UEFI
support is Windows 7.

OvmfPkg/README has some comments on Windows support:

If you'd like to virtualize Windows XP on QEMU/KVM, please use SeaBIOS for
guest firmware.

You can also try to build OVMF with -D CSM_ENABLE, but for that, you'll
have to build SeaBIOS in CSM mode first, and embed that binary into OVMF
at build time. Please ask David for details (CC'd).

Thanks
Laszlo

Hi Laszlo
	Thank you very much for your great support.

Hi David

Hi David 

	I have found this compiled OVMF-with-csm.fd can support winxp booting up.
	OVMF-with-csm.fd path: https://www.kraxel.org/repos/jenkins/seabios/seabios.git-csm-1.12.0-33.63.g43f5df7.x86_64.rpm
	Then could you help to provide me the compile method and base code to reproduce this OVMF-with-csm.fd?

Ah, good point, I should have remembered that Gerd offers a CSM build in
his repo!

So, you can easily look up the build instructions, in Gerd's SeaBIOS and
OVMF RPM "spec" files. Check out these git repositories:

  https://git.kraxel.org/cgit/jenkins/seabios/
  https://git.kraxel.org/cgit/jenkins/edk2/

Specifically:

  https://git.kraxel.org/cgit/jenkins/seabios/tree/seabios.git.spec
  https://git.kraxel.org/cgit/jenkins/edk2/tree/edk2.git.spec.template

HTH,
Laszlo

Right, thanks.

Ultimately it's as simple as:

 • Build SeaBIOS with CONFIG_CSM
 • Drop the resulting Csm16.bin into OvmfPkg/Csm/Csm16/ in the EDK2 tree
 • Build EDK2 with -DCSM_ENABLE

Someone else mailed me recently to say they'd copied the Csm packages
over from OvmfPkg to Quark and had Windows booting on Galileo boards.  

Hm, I wonder if we should move the CSM support out of OVMF and into
somewhere more generic, since it really is generic and not platform-
specific?

Thanks David, follow these steps, I can reproduce the OVMF-with-csm.fd.
However, I find that when I choose remotes/origin/master branch, after compiling, qemu+kvm+ovmf+winxp can't 
boot up, but when I choose remotes/origin/UDK2018, the compiled OVMF.fd can work.
So the latest edk2 code have removed CSM support? Could I apply the CSM patch to 
the latest edk2 code to support my work because our project is based on the latest EDK2 code, thanks.

I can't make some decisions, from my view, maybe CSM module can be 
an independent patch for user to apply or reject :)

Junhao

FYI there is a regression in master for OVFM right now: https://bugzilla.tianocore.org/show_bug.cgi?id=2266 so you might be hitting that.

We moved the CSM infrastructure under OvmfPkg because IntelFrameworkPkg
/ IntelFrameworkModulePkg were slated for removal, and this was how we
could salvage the CSM:

https://bugzilla.tianocore.org/show_bug.cgi?id=1811

We could likely move it out of OVMF, but if the destination is still the
edk2 tree -- which I would strongly prefer, as long as we support the
CSM at all --, then it will take a new top level directory (CsmPkg, for
example).

No other package maintainer was willing to maintain the CSM, and even
under OvmfPkg, I agreed to it only if you'd assume its reviewership. So
now you'd likely have to introduce CsmPkg, and become its sole (or
primary) maintainer.

I'm 100% OK with that. (Both as OvmfPkg co-maintainer, and as one of the
stewards that might have to ACK (I think?...) the creation of another
top-level directory).

Thanks
Laszlo
