question about qemu+kvm+ovmf+winxp
|
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

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).

Thank you very much for your great support. Hi David Refer to http://www.linux-kvm.org/downloads/lersek/ovmf-whitepaper-c770f8c.txt. Interested users and developers should look for OVMF's "-D CSM_ENABLE" build-time option, and check out the <https://www.kraxel.org/repos/> continuous integration repository, which provides CSM-enabled OVMF builds. Could you help me to choose which branch supporting CSM, and more details, thanks very much. Thanks, Junhao

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? Thanks, Junhao

Hi DavidAh, 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 -----Original Message-----

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?

-----Original Message-----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. Someone else mailed me recently to say they'd copied the Csm packagesI 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. Thanks, Andrew Fish

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
