[Qemu-devel] User-space emulation on Mac OS X to run Mac OS X Intel applications
Hi all, Looking at qemu, it seems as if it could be possible to allow it to run Intel OS X apps on PowerPC OS X, much like a reverse Rosetta. The x86 frameworks/libraries are included with Xcode, so possibly everything else could run natively, just have the app itself emulated. Is anybody willing to try getting this to work?

[Qemu-devel] Problems with Qemu 0.7.2
(With or without kqemu) 1) When switching from qemu, it doesn't like letting go of the mouse. If you don't have it grabbed, and click on another window, it will grab the mouse again, and the title bar will cycle through "Qemu" and "Qemu - Press ctrl-alt to exit grab. If you use the keyboard to move the focus, it acts as it should (in other words, no qemu grabbing). 2) "Video memory" is somehow being corrupted by changing resolution. See: http://kirk.math.twsu.edu/family/james/pics/computer/qemu-visual-errors1.png for the effect of switching from 800x600 to 640x480. (The other way it does not result in corruption.) Also changing from 16-bit to 24-bit causes corruption. (Similar to that seen in the screenshot. I can't detect a definite pattern, other than text and some icons display correctly.) 3) The video doesn't appear to handle ARGB as can be seen in the screenshot: http://kirk.math.twsu.edu/family/james/pics/computer/swiftshader-errors.png If you zoom in on that one, to see individual pixels, one can notice a dark, blue, green, red pattern.

But this doesn't really help you anyways. The m68k target supports a very simple semihosting syscall layer, similar to the the "angel" swi interface already implemented on Arm targets. Neither of these help darwin emulation. It's worth noting that OSX has two types of syscalls. IIRC one uses positive syscall IDs, th other negative: - The Darwin syscalls. Thees are more-ore-less the same as the linux layer, and should be fairly easy. You can also examine/borrow from the open source Darwin kernels. - The Mach syscalls, and all the message passing bits (eg IOkit). Some (many?) of these are proprietary. Might not be too hard to pass these through to an OSX host, but I wouldn't bet on it. Paul ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
[Qemu-devel] qemu-ppc fails to run clone with CLONE_VM, threaded programs, non-static programs
Hello,
I'm attempting to run cross-compiled programs with qemu-ppc. Basic
statically-linked programs work perfectly. However, if I attempt to run
non-static programs or threaded programs, or if I attempt to call
clone() with the CLONE_VM flag set, I get an invalid data memory access.
Threaded programs get an error when calling pthread_create, with an
invalid data memory access at 0x0018. A simple test program using
clone with CLONE_VM gets an invalid data memory access at 0x0008.
Non-static programs get an invalid data memory access at various
addresses around 0x0de0, before ever reaching main().
I've attached the test program I used to test clone(), as it seems to be
the simplest test case which fails. I'd be happy to help with debugging
this problem; if you need any more information or you'd like me to run
additional tests, please let me know.
I've tested both the Debian-packaged qemu-7.0 and an unmodified
qemu-0.7.2 from qemu.org ; with the latter, all of the above tests still
fail, but I get a few more error messages along the lines of "Invalid
segfault errno (a00)" and "qemu: uncaught target signal 11
(Segmentation fault) - exiting". In addition, when I run the
hello-clone program under qemu-7.2, the parent also experiences an
"invalid data memory access" error and segfaults, whereas with 7.0 the
parent ran fine and only the child had an "invalid data memory access"
error and segfault.
Some background: I'm a member of the Portland State Aerospace Society,
and we're in the process of switching our rocket's flight computer
(which runs Debian GNU/Linux) over to PowerPC. I'm attempting to get our
flight-control software to run under qemu-ppc so that I can test it
under simulation; the flight-control software currently makes use of
pthreads.

I worked with pbrook on #qemu to debug this issue. The problem turns
out to be that qemu's do_fork function on PowerPC zeroes out r7-r31 in
the new CPU state structure after a clone, which it should not do, as
the child's registers should match the parent; it also does not zero
register r3, which holds the return value and should be zero in the
child. I've prepared and attached a patch which should solve this problem.
