[Qemu-devel] Adding support for Mac OS X ppc64 host

[Qemu-devel] Adding support for Mac OS X ppc64 host

[Andreas Faerber]

Hello,

This mini series adds TCG target support for OSX/ppc64
and fixes the Cocoa frontend for ppc64.

With these patches applied, qemu and qemu-system-x86_64
are usable. Tested on Mac OS X v10.5 with a Haiku disk image
and a Fedora 12 installation disk.

qemu-system-sparc works fine, too.

qemu-system-sparc64 works on ppc64 while it didn't on ppc!
qemu-system-ppc appears to hang on ppc64 but doesn't on ppc.

I suggest we start applying these patches and try to fix
these weird issues afterwards.

Regards,

Andreas

[Qemu-devel] [PATCH 1/3] TCG: Mac OS X support for ppc64 target

[Andreas Faerber]

Darwin/ppc64 does not use function descriptors,
adapt prologue and tcg_out_call accordingly.
GPR2 is available for general use, so let's use it.

[Qemu-devel] [PATCH 2/3] Cocoa: ppc64 host support

[Andreas Faerber]

Fix integer usage in the Cocoa backend: NSInteger is long on LP64.

http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSView_Class/Reference/NSView.html#//apple_ref/doc/uid/20000014-BBCFHHCD

This makes the graphical display show up on a ppc64 host.

No need to add R13, it's reserved anyhow.

The frame format is different to that of PPC-elf64abi, shouldn't really
make a difference here, then again i don't have access to PPC64 Mac OSX,
so can't really verify that.

Otherwise looks good.. Should i commit it with R13 fixed?

I checked that the linkage area is 48, too, the LR offset is 16, too.
The parameter area was depicted as 64 < 128.
So I guess we're good there.

> Otherwise looks good.. Should i commit it with R13 fixed?

About the callee-save stuff I was less certain. Feel free to make  
modifications (e.g., moving tcg_out_call up?) or have me resubmit.

Sorry, i don't get this part, i was just thinking of removing R13 from
the list. Moving tcg_out_call?

[Qemu-devel] [PATCH v2 1/3] TCG: Mac OS X support for ppc64 target

[Andreas Faerber]

Darwin/ppc64 does not use function descriptors,
adapt prologue and tcg_out_call accordingly.
GPR2 is available for general use, so let's use it.

http://developer.apple.com/mac/library/documentation/DeveloperTools/Conceptual/LowLevelABI/110-64-bit_PowerPC_Function_Calling_Conventions/64bitPowerPC.html

v2:
- Don't mark reserved GPR13 as callee-save.
- Move tcg_out_b up.
- Fix unused variable warning in prologue.

Interesting! Unfortunately I don't have a PPC64 Apple machine handy, so I can't test it.

I cc'ed you so that you could check your earlier x86_64 Mac patch  
series, if you care. I don't have an x86_64 Mac at hands myself.

Btw I'll be looking into bringing the Cocoa frontend on par with SDL,  
namely closing the app when closing the window and not creating the  
window in -nographic mode. That's awful when debugging!

Oh I see, I'll test it later today or tomorrow.

I agree. I did a patch for that once - might be worth searching the ML for that. Basically it searched the args for a "-nographic" parameter. Pretty hacky, but at least it worked.

I know that this is endorsed by apple since 10.5 but NSInteger will break compiling on Tiger and older. Int on the other hand is only throwing a warning on Leopard if I'm not mistaken.

Especially with qemu, one has to have an eye on the type... NSInteger can be an int or a long, depending on the host...

#if __LP64__ || NS_BUILD_32_LIKE_64
	typedef long NSInteger;
	typedef unsigned long NSUInteger;
#else
	typedef int NSInteger;
	typedef unsigned int NSUInteger;
#endif

I have no G5 at hand to test either.

You appear to be right there... no trace of it in 10.4u SDK.

On Leopard ppc it just warns and works because NSInteger == int.
On Leopard ppc64 it warns and fails at runtime because NSInteger != int.

Right, so we do need NSInteger - I'll add a version check. Thanks for  
the feedback!

[Qemu-devel] [PATCH v3 1/3] TCG: Mac OS X support for ppc64 target

[Andreas Faerber]

Darwin/ppc64 does not use function descriptors,
adapt prologue and tcg_out_call accordingly.
GPR2 is available for general use, so let's use it.

http://developer.apple.com/mac/library/documentation/DeveloperTools/Conceptual/LowLevelABI/110-64-bit_PowerPC_Function_Calling_Conventions/64bitPowerPC.html

v2:
- Don't mark reserved GPR13 as callee-save.
- Move tcg_out_b up.
- Fix unused variable warning in prologue.

Sorry, I meant tcg_out_b. Just declaring it was the least intrusive  
patch.

I've sent a v2 series, doing the above plus silencing a warning.
They are also available for pulling from git://repo.or.cz/qemu/ 
afaerber.git, branch tcg-osx-ppc64.

Does it work on linux ppc64? If so how exactly did you test that
(so that i can try to debug it here)

Haven't had a chance to test on other ppc[64] platforms yet.

On Linux add -nographic.

I was only able to find debian-40r3-sparc-netinst.iso here on ppc/linux
it boots (i think):

<snip snip>
boot: expert
Allocated 8 Megs of memory at 0x40000000 for kernel
Loaded kernel version 2.6.18
Loading initial ramdisk (3882238 bytes at 0xC00000 phys, 0x40C00000 virt)...
-
Remapping the kernel... done.
Booting Linux...

And it sits there while i'm losing patience..

Can you retry with netinst, if it behaves like CD-1 in your case the
problem is most likely confined to OSX, otherwise i would have to search
for CD-1 better.

Thanks will try system-ppc later..

I've tried Debian 4.0r4a ppc netinst CD on Linux/ppc64 and spotted  
different but similar deviations:

ppc64 qemu-system-ppc segfaults after "returning from prom_init".
ppc64 qemu-system-ppc64 boots the default "install" option fine.

amd64 qemu-system-ppc does not exhibit this crash.
amd64 qemu-system-ppc64 boots okay, too.

Weird things going on there, it fails (but only semi-reliably!) inside
helper_lsw it appears that while argument passed to it is correct the
memory reference (inside ldl) uses sign extended version of the address.

I'm a bit stumped...

Should be fixed by 591d6f1dfdb60ab0a4cc487cd5781fa799dcac4b, can you
verify?

Verified-by: Andreas Färber <andreas.faerber@web.de> :)

ppc-softmmu no longer crashes on Linux/ppc64. Didn't notice any  
regression or improvement on OSX/ppc64 - no influence on x86/x64 Haiku  
or sparc64 Debian on Linux/ppc64.

Good catch, thanks!

I tried with 4.0r8 businesscard: Such a hang I could reproduce on  
Linux/ppc and Linux/ppc64 and OSX/ppc64 and Linux/amd64 only when  
running with qemu-system-sparc64, but not with qemu-system-sparc.

Also, on Linux/ppc64, qemu and qemu-system-x86_64 render Haiku nightly  
image r34558 x86gcc2 unusable (desktop garbled, no cursor), while on  
Linux/ppc and OSX/ppc64 (r34514) and Linux/amd64 it works okay.

So the problem is in no way limited to ppc, good to know.

That's vga/display issue (have you tried -vga std ?, FranГois REVOL 
mentioned that it works with one of those and doesn't work with others)
