Hi,
There's a good chance this is the same as lp 1714331 - fixed by a newer OVMF.

Title:
Windows 7 guest won't boot on qemu 2.10 (works on 2.9)
Status in QEMU:
New
Bug description:
Qemu version: 2.10 stable.
Guest: Windows 7 SP1 x64, virtio drivers are already installed in the guest.
Command line:

Windows hangs at boot with waving flag screen (flag doesn't freeze,
keeps waving indefinitely). Same command line boots fine with Qemu
2.9. I tried changing machine type to pc-q35-2.9 - same result.

Ok, so I cloned from github and am bisecting like this (it's been a while, correct me if I'm wrong):

It's just the newer compiler is more fussy than the old one so when you
bisect you're not getting fixes for newer compilers. You can pass
flags to the configure to use extra clfgas to turn this particular
warning off.

The newer GCC compilers are more fussy - just add '--disable-werror'
when running 'configure' to make it ignore the warning

Just did a test to be sure: pulled latest git
(a9158a5cba955b79d580a252cc58ff44d154e370) - guest didn't launch.
Reverted 208fa0e43645edd0b0d8f838857dfc79daff40a8 - guest launched
successfully.
Can someone please take a look at this? I don't want to get stuck at
2.9.0 :)

Windows hangs at boot with waving flag screen (flag doesn't freeze,
keeps waving indefinitely). Same command line boots fine with Qemu
2.9. I tried changing machine type to pc-q35-2.9 - same result.

Did a bit of testing: w7 iso boots to install screen with seabios but
stuck at win boot logo with ovmf.
I've heard (maybe wrongly) that seabios would also break in that case.

Thanks, Gerd, for the CC -- I agree, this commit (208fa0e43645) almost

OVMF places the VBE Shim into the C segment, and points the 0x10

looking at it more, question is why do we have a separate
piece of ram mapped here that overlays system ram.
Can we remove this memory region and let guest use
underling initial memory?

I'd also like to mention that, when we originally worked on the VBE
Shim, I tried to put it elsewhere. Obviously it has to be pointed-to by
a real mode interrupt vector, which limits quite a bit where it can go
at all; the point is that I tried to put it into low *RAM* (under
640KB).
It didn't work. Windows 7 would only accept the VBE Shim when it existed
in the C segment, i.e. where a VGA option ROM would normally be located.
This is just to say that moving the VBE Shim out of the C segment (into
real-mode addressible RAM) will not work.
The symptom described in the original report is likely due to
- Windows following the 0x10 interrupt vector (from page 0) to the C
segment,
- copying a bunch of zeros into its real mode emulator from the C
segment (where now no actual VBE code can be found),
- and then seeing no results when the real mode emulator executes the
zeros.

What I mentioned earlier was not that SeaBIOS would break.
Instead, I said that building OVMF, with the SeaBIOS CSM (Compatibility
Support Module) embedded into it, would break, exactly the same way as
the VBE Shim.
Quoting the CSM Spec from Intel: "The CSM provides compatibility support
between the Framework and traditional, legacy BIOS code and allows
booting a traditional OS or booting an EFI OS off a device that requires
a traditional option ROM (OpROM)."
https://github.com/tianocore/tianocore.github.io/wiki/Compatibility-
Support-Module
Upstream edk2 contains no such module out of the box. However, SeaBIOS
has been extended with a build target (CONFIG_CSM) that produces such a
binary. This binary can be then embedded in the edk2 source tree (see
"OvmfPkg/Csm/Csm16/ReadMe.txt"), and then OVMF can be built with -D
CSM_ENABLE.
This will allow OVMF to boot legacy OSes, and those OSes will think they
are being booted on a legacy BIOS machine.
While the SeaBIOS CSM itself is provided by the SeaBIOS project, the
infrastructure that sets it up under UEFI comes from edk2. The two
important drivers are -- built into OVMF only with -D CSM_ENABLE --:
- IntelFrameworkModulePkg/Csm/LegacyBiosDxe/LegacyBiosDxe.inf
- IntelFrameworkModulePkg/Csm/BiosThunk/VideoDxe/VideoDxe.inf
The former driver (LegacyBiosDxe) needs write access to the memory area
at 0xc0000, so that it can install legacy PCI option ROMs. The service
it provides is called "EFI_LEGACY_BIOS_PROTOCOL.InstallPciRom"; it loads
a traditional OpROM into traditional OpROM address space (0xC0000 to
0xFFFFF region).
The latter driver (VideoDxe) asks the former driver to install such an
option ROM (for video services) from the PCI ROM BAR.
Therefore, if the area at 0xc0000 is unwriteable for the guest, then
neither the VBE Shim, nor its alternative -- namely the full-blown
SeaBIOS CSM -- can function in OVMF.

ovmf seems to not touch pam configuration, so rom remains mapped.
seabios in contrast maps the address range to ram instead.
IIRC ovmf does that too in CSM mode.
So, yes, probably this is fixable in ovmf.

I don't understand; the code that I quoted above -- and that LaunchPad
messed up -- explicitly changes the PAM registers:
//
// Put the shim in place first.
//
Pam1Address = PCI_LIB_ADDRESS (0, 0, 0, 0x5A);
//
// low nibble covers 0xC0000 to 0xC3FFF
// high nibble covers 0xC4000 to 0xC7FFF
// bit1 in each nibble is Write Enable
// bit0 in each nibble is Read Enable
//
Pam1 = PciRead8 (Pam1Address);
PciWrite8 (Pam1Address, Pam1 | (BIT1 | BIT0));
...
//
// Clear Write Enable (bit1), keep Read Enable (bit0) set
//
PciWrite8 (Pam1Address, (Pam1 & ~BIT1) | BIT0);

I don't see how.

Re: comment 14, "is there a way to fix vbeshim instead of reverting RO
limitation that commit introduced?":
I don't think so; please see my earlier comments 15 and 17. To
elaborate:
If a user wants to boot Windows 7 on OVMF, they have *three* options:
(1) Build the SeaBIOS CSM (CONFIG_CSM=y), and embed it into OVMF, like
described above. Then, boot Windows 7 in *Legacy Mode*.
--> Windows 7 will think that it runs on a plain BIOS machine. The VBE
Services will be provided to Windows 7 by (a) the edk2 CSM
infrastructure, (b) the SeaBIOS CSM, and (c) the VGABIOS PCI oprom
together.
(2) Build the SeaBIOS CSM (CONFIG_CSM=y), and embed it into OVMF, like
described above. Then, boot Windows 7 in *UEFI Mode*.
--> Windows 7 will think that it runs on a UEFI machine, *but* because
Windows 7 has a bug, it will want to invoke VBE services nonetheless.
The VBE Services will be provided to Windows 7 by (a) the edk2 CSM
infrastructure, (b) the SeaBIOS CSM, and (c) the VGABIOS PCI oprom
together.
(3) Build OVMF without the SeaBIOS CSM, then boot Windows 7 in UEFI
Mode.
--> Windows 7 will think that it runs on a UEFI machine, *but* because
Windows 7 has a bug, it will want to invoke VBE services nonetheless.
The VBE Services will be provided to Windows 7 by the VBE Shim that OVMF
installs during boot.
Option #1 and option #2 no longer work because the CSM infrastructure in edk2 needs to be able to write 0xc0000.
Option #3 no longer works because OVMF needs to put the VBE Shim into
place at 0xc0000.
Basically, Windows 7 wants to find the VBE services at 0xc0000, regardless of the method that it is booted with, ie. Legacy or UEFI. (As I said, this is a Windows 7 bug.) If that memory area is not writeable to the guest, then OVMF cannot satisfy the (buggy) Windows 7 requirement, using either of options #1, #2 or #3.

Correct, and that's because edk2 commit db27e9f3d8f0 fixed the PAM
register offsets for Q35, in the CSM platform support. At that time we
missed that the same should be done in the VBE Shim as well.
I'm going to do it for the VBE Shim now.
(I'm pretty sure UEFI Windows 7 boots fine with the VBE Shim right now,
on QEMU 2.10, if the machine type is i440fx, not q35.)
Thanks for the help!

Ahh, wait, now I remember something -- the PAM registers are at a
different location on Q35!!!
If that's what's wrong, then it is indeed an OVMF bug. Let me see if I
can write a patch.

Indeed the CSM platform support had the same error one and half years
ago, see:

Thank you, Gerd, for the hint!

Title:
Windows 7 guest won't boot on qemu 2.10 (works on 2.9)
Status in QEMU:
New
Bug description:
Qemu version: 2.10 stable.
Guest: Windows 7 SP1 x64, virtio drivers are already installed in the guest.
Command line:
qemu-system-x86_64 \
-nodefaults \
-nodefconfig \
-machine type=q35,accel=kvm \
-enable-kvm \
-cpu host \
-m 2048 \
-vga virtio \
-boot menu=on \
-smbios file=/path/dmidecode_BIOS.bin \
-acpitable file=/path/acpi_slic.bin \
-bios /path/OVMF_CODE.fd \
-net none \
-drive if=virtio,media=disk,file=/media/win7.qcow2 \
-device pcie-root-port \
-device ich9-usb-ehci1 \
-device ich9-usb-uhci1 \
-device ich9-usb-uhci2 \
-device ich9-usb-uhci3
Windows hangs at boot with waving flag screen (flag doesn't freeze,
keeps waving indefinitely). Same command line boots fine with Qemu
2.9. I tried changing machine type to pc-q35-2.9 - same result.

I CC'd Aleksei on the series, but testing is welcome from anyone. (The

I assume this has been completely fixed in edk2, so I'm closing this
QEMU bug now.
