What about not disabling Cocoa, and simply print a nice #error or #warning that explains that the quickdraw part needs fixing? Pierre.

I meant send a diff to the qemu-devel in a new mail with [Patch] in the subject so that it can be committed :-) However, at second thought, I think that it might need some re-work, see [1], and the arguments might need to be byte-swapped. Any suggestions how to fix this? As I said before, I think that the problem appears because: qemu signal handlers might be overridden by some mach calls, that could explain the problem you are encountering. We need to work on this. That's really not easy to fix, in two words. [1] I think it should consist in writing a custom implementation of semaphore_signal_trap, semaphore_signal_thread_trap, semaphore_wait_signal_trap, etc. that hook into signal.c.

I would guess mprotect is there for a reason so it doesn't seem like a good solution, besides the runs get substantially slower without mprotect.

[Qemu-devel] [Patch] siginfo fix for Darwin/Mac OS X
Hi, This patch is an attempt to suppress the anonymous struct siginfo trick, as it doesn't work on darwin since struct siginfo isn't defined, and stay anonymous. Here I use siginfo_t, assuming that it is defined on most platform. But feel free to add a typedef struct siginfo siginfo_t; for your platform if needed, or some other trick. (Variation of this hack is possible as struct __siginfo is valid on darwin. Feel free to use) Pierre.

Why does this make a difference?
struct siginfo is not defined on darwin. (it works because struct
siginfo is defined also as an anonymous structure in qemu header)
But after re-thinking, my patch is rather unelegant. I think we
should definitely use a void * type for info, rather than using the
anonymous struct siginfo trick. Any thought?

The cocoa video driver is lighter than the SDL one, since it doesn't require the SDL dependencies. And I don't get the full-screen point: cocoa.m still need much work, and that is why it doesn't support fullscreen (yet). (BTW Mike has been doing some great improvements which will be hopefully soon committed in the head cvs repository.) Hence the suggestion to go full SDL. Fabrice would like to see the native GTK, or Win32 qemu video coded. Because then a decent UI could be added to qemu. The front ends will always be limited, and the previous hack seems a bit crazy, and nearly nasty: you can do that directly via a video driver for qemu, and moreover it will let you far more control over qemu.

Pierre d'Herbemont, I have changed cocoa.m (0.7.0) to use openGL with very fast texturing. I removed the use of QuickDraw. The DisplayState data is now DMA'd to the graphics card instead of copied by the CPU. This uses apple's texture range extensions. The change means that the transfer of display memory incurs no CPU overhead. I also put in a bit more mouse stuff, and made some other fixes. I can't work out how to get the Window to get focus once it loses it, which is really a pain. I Shark'd it to make sure there wasn't any overhead from the texturing. I tested with Knoppix and FreeDOS. I am not sure if this is of interest to people, I just had a lazy weekend.

It is definitely a bug in Apple assembler I would say, so I suggest you
add a comment in the above patch in order to avoid somebody later on

I thought it was, but it seems to be not so buggy ;)
I have had a look at the Apple's as source code of Darwin 8.0 (10.4)
[1] and I have found an interesting comment :
/*
* If this is the mtcrf opcode (0x7c000120) and val is not zero and
* has exactly one bit set then use the new form of the mtcrf
* opcode. This has bit 0x0010 set and the FXM field is a bit
* mask. Else use the old form without bit 0x0010 set.
*/
I don't know what they are refering to, but that may have been
introduced by the PowerPC 970 or an other new PPC, since it was not
present on the Mac OS X 10.2's as [2].

[Qemu-devel] [Patch] target-ppc mtcrf instruction not recognized
Hi,
I have been playing with ppc-darwin-user. And I have to say that qemu-
ppc is too strict with ppc opcode validity:
On Mac OS X binary release called Tiger (or 10.4), the __bzero
function [1] contains a mtcrf, which has been translated to
0x7c901120, by Apple's as. Current qemu rejects it, saying it is
invalid. According to the IBM Specification the mtcrf instruction
[2], contains reserved flags, for which the values are unknown. qemu
assumes that those are set to 1, which is obviously wrong. The
attached patch provides a fix.
The mtcrf case might not be the only case in which such a situation
occurs. That would need a special attention, though being strict is
better than letting pass.
Pierre.
