[Qemu-devel] [PATCH 0/9] Intel Mac target support

[Qemu-devel] [PATCH 0/9] Intel Mac target support

[Alexander Graf]

Hi,

the following patchset enables qemu to run Mac OS X with disabled
AppleIntelCPUPowerManagement.kext, by emulating hardware that resembles
an Intel Mac close enough. The following patches are included:

1. DMI
This is based on the DMI support by Ryan Harper. As it is currently
unclear, if this approach is taken or if the Bochsbios is going to be
patched, I would recommend to not apply this patch for now. I still
submit it for completeness and because I have touched parts of it.

2. HPET
This adds an HPET emulator device. It is not feature-complete but should
suffice for this purpose.

3. LPC
This adds a dummy LPC device the HPET is located on.

4. AppleSMC
Apples binary protection sits in the fan control, which is the AppleSMC
chip. This emulates the devices and takes the protective key from the
command line.

5. CoreDUO
Mac OS X as is has a condition to only run on family 13 Intel CPUs, so
this adds a definition for a CoreDuo CPU and an MSR as well as a CPUID
instruction that is required by Mac OS X

6. IDE
The oldest supported IDE controller in Mac OS X is the ICH6. This is an
incomplete implementation for that controller, that suffices for running
Mac OS X and worked with libata for me as well.

7. IntelMac
To leave the default behavior unchanged, this adds a "mac" machine
definition that automatically chooses the right hardware for an emulated
Intel Mac.

8. Multiboot
To boot Mac OS X a mach bootloader has to be run. David Elliot modified
the original i386 Mac OS X BIOS based bootloader to emulate the EFI
entries and support multiboot, an easy but straight-forward kernel
loading interface founded by grub. To boot multiboot-compliant kernels
directly, this adds support for multiboot loading to the -kernel option.

9. Bochsbios
Several ACPI entries were missing from the bios and the new controllers
need to be initialized properly.
This patch is against the bochsbios. Should this rather be sent to the
bochs ML?

Cheers,

Alex

I'm really having a hard time understanding if this is irony or not ;-).

I don't think there's irony as qemu is the first emulator fit for  
Leopard[1], AFAIK.

[1] For non-Apple freaks: "Leopard", that's Mac OS X v10.5, the most  
recent Macintosh OS.

Well, no, it's not an irony, and I'm really happy with such
advancement and I'm looking forward at trying that, with both Qemu,
KQemu and KVM.
