Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:
Linux kernel >= v6.2 no longer boots on Apple's Virtualization.framework (x86_64).
It is reported that the issue is not reproducible on ARM64: https://github.com/lima-vm/lima/issues/1577#issuecomment-1561577694
## Reproduction
Checkout the kernel repo, and run `make defconfig bzImage`.
Create an initrd (see the attached `initrd-example.txt`)
Transfer the bzImage and initrd to an Intel Mac.
On Mac, download `RunningLinuxInAVirtualMachine.zip` from https://developer.apple.com/documentation/virtualization/running_linux_in_a_... , and build the `LinuxVirtualMachine` binary with Xcode. Building this binary with Xcode requires logging in to Apple. If you do not like logging in, a third party equivalent such as https://github.com/Code-Hex/vz/blob/v3.0.6/example/linux/main.go can be used.
Run `LinuxVirtualMachine /tmp/bzImage /tmp/initrd.img`. v6.1 successfully boots into the busybox shell. v6.2 just hangs before printing something in the console.
## Tested versions
v6.1: OK ... v6.1.0-rc2-00002-g60f2096b59bc (included in v6.2-rc1): OK v6.1.0-rc2-00003-g5c62d5aab875 (included in v6.2-rc1): NG <-- This commit caused a regression ... v6.2-rc1: NG ... v6.2: NG ... v6.3.0-rc7-00181-g8e41e0a57566 (included in v6.3): NG <-- Reverts 5c62d5aab875 but still NG ... v6.3: NG v6.4-rc3: NGTested on MacBookPro 2020 (Intel(R) Core(TM) i7-1068NG7 CPU @ 2.30GHz) running macOS 13.4.
The issue seems a regression in [5c62d5aab8752e5ee7bfbe75ed6060db1c787f98](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...) "ACPICA: Events: Support fixed PCIe wake event".
This commit was introduced in v6.2-rc1, and apparently reverted in v6.3 ([8e41e0a575664d26bb87e012c39435c4c3914ed9](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...)). However, v6.3 and the latest v6.4-rc3 still don't boot.
See bugzilla for the full thread.
Interestingly, this regression still occurs despite the culprit is reverted in 8e41e0a575664d ("Revert "ACPICA: Events: Support fixed PCIe wake event""), so this (obviously) isn't wake-on-lan regression, but rather early boot one.
Also, the reporter can't provide dmesg log (forget to attach serial console?).
Anyway, I'm adding it to regzbot:
#regzbot introduced: 5c62d5aab8752e https://bugzilla.kernel.org/show_bug.cgi?id=217485 #regzbot title: Linux v6.2+ (x86_64) no longer boots on Apple's Virtualization framework (ACPICA issue)
Thanks.
