Title:
efifb on Linux guest fails to load when using VGA passthrough
Status in QEMU:
New
Bug description:
The EFI framebuffer fails to load when booting a Gentoo guest using
ovmf + vga_passthrough. I retested using they system rescue CD and
saw the same issue, but also noticed that when a second framebuffer
loads, nouveaufb in my case, the terminal appears. I have also
verified that the Gentoo min CD is not hanging at boot as I can type
'poweroff' after waiting a few minutes and the system responds by
powering off. I am unable to reproduce with seabios as I have been
unable to get vga passthrough to work with that BIOS.
Steps to Reproduce:
1. Install qemu and ovmf
2. Download systemrescuecd-x86-5.3.1.iso
3. Run qemu using one of the configurations below
4. Select first boot option in GRUB menu
5. Wait 30 seconds
6. Press enter # System rescue is prompting for the keymap between steps
5 and 6
7. Wait 2 minutes
8. Observe fb console
9. Note lack of output until very late in boot process
10. Check dmesg
11. Note efifb failed to load (invalid address)
12. Note nouveaufb started late in boot process
Expected Results:
The EFI FB to load and display output to monitor. This is the behavior I
see when booting the host system via UEFI.
Actual Results:
The EFI FB fails to load and display output. System fails to display any
output until nouveaufb loads. When booting using the Gentoo minCD, this makes
the system largely unusable.
Additional information:
Tested using Gentoo's app-emulation/qemu-3.0.0 version. Bug report:
https://bugs.gentoo.org/669880
I also tested qemu at git commit
179f9ac887973c818b2578bd79fa3ed2522657d4. Configuration log for the
build will be attached.
