Hi Mark, Yes I am getting the emails from qemu-devel thanks (seems pretty slow though - the website is faster) I replied to a couple but its over my head mostly now! I didn't notice Michael had done a v2 patch for 5.1, that's fine with me.

Great work Simon! I'm not an ACPI expert but that certainly seems a plausible solution - I'll have to defer the final review to someone else though. The quickest way to get this reviewed is to follow the procedure at https://wiki.qemu.org/Contribute/SubmitAPatch which is basically send a "git format-patch" email to the qemu-devel mailing list. Adding as CC the appropriate maintainers shown by running "./scripts/get_maintainer.pl /path/to/my.patch" as indicated in Section 2.1 "CC the relevant maintainer" will help ensure it gets the attention of the right people.

No worries - I didn't spot that those memory regions were implemented as
single-byte registers which means the access size won't matter anyway.
I had a quick look at your command line again and the only other obvious
thing I spotted was that a 64-bit access to the q35 "blackhole" region
might also be affected by this change in logic. Does the diff below help
at all?

Thanks for the bisection, that's really helpful - that particular patch
fixes the way in which memory region access sizes are treated as valid.
The obvious device to look at here is isa-apple-smc since I suspect that
has less CI coverage.

- does the following patch help at all?

memory: Revert "memory: accept mismatching sizes in
memory_region_access_valid"
Memory API documentation documents valid .min_access_size and
.max_access_size
fields and explains that any access outside these boundaries is blocked.
This is what devices seem to assume.
However this is not what the implementation does: it simply
ignores the boundaries unless there's an "accepts" callback.
Naturally, this breaks a bunch of devices.
Revert to the documented behaviour.
Devices that want to allow any access can just drop the valid field,
or add the impl field to have accesses converted to appropriate
length.

Title:
Qemu after v5.0.0 breaks macos guests
Status in QEMU:
New
Bug description:
The Debian Sid 5.0-6 qemu-kvm package can no longer get further than
the Clover bootloader whereas 5.0-6 and earlier worked fine.
So I built qemu master from github and it has the same problem,
whereas git tag v5.0.0 (or 4.2.1) does not, so something between
v5.0.0 release and the last few days has caused the problem.
Here's my qemu script, pretty standard macOS-Simple-KVM setup on a
Xeon host:
qemu-system-x86_64 \
-enable-kvm \
-m 4G \
-machine q35,accel=kvm \
-smp 4,sockets=1,cores=2,threads=2 \
-cpu
Penryn,vendor=GenuineIntel,kvm=on,+sse3,+sse4.2,+aes,+xsave,+avx,+xsaveopt,+xsavec,+xgetbv1,+avx2,+bmi2,+smep,+bmi1,+fma,+movbe,+invtsc
\
-device
isa-applesmc,osk="ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
\
-smbios type=2 \
-drive if=pflash,format=raw,readonly,file="/tmp/OVMF_CODE.fd" \
-drive if=pflash,format=raw,file="/tmp/macos_catalina_VARS.fd" \
-vga qxl \
-device ich9-ahci,id=sata \
-drive id=ESP,if=none,format=raw,file=/tmp/ESP.img \
-device ide-hd,bus=sata.2,drive=ESP \
-drive id=InstallMedia,format=raw,if=none,file=/tmp/BaseSystem.img \
-device ide-hd,bus=sata.3,drive=InstallMedia \
-drive id=SystemDisk,if=none,format=raw,file=/tmp/macos_catalina.img \
-device ide-hd,bus=sata.4,drive=SystemDisk \
-usb -device usb-kbd -device usb-mouse
Perhaps something has changed in Penryn support recently, as that's
required for macos?

Also on a related note, kernel 5.6/5.7 (on Debian) hard crashes the
host when I try GPU passthrough on macos, whereas Ubuntu20/Win10 work
fine - as does 5.5 kernel.

[Bug 1886318] Re: Qemu after v5.0.0 breaks macos guests
Indeed it is, but bear in mind it was QEMU 5.1 release feature freeze this week so most developers are busy rebasing and fixing up bugs from the resulting merge. Given that you have already built QEMU from source, what would help enormously is if you can do a "git bisect" between the v5.0.0 tag (working) and your current master (not working) and provide the output of "git bisect log" in this bug report. By identifying the individual commit that broke your test case, it is much easier for developers to understand the issue and propose a fix.
