Re: [Qemu-devel] Binaries for Windows
Dear all. This is my first post. My name is TAKEDA, toshiya. As Kazu announced, I work for Windows port binary release untill he comes back. I am developing mainly old Japanese computer/console emulators and now trying to implement NEC PC-98x1 architecture on QEMU. PC-98x1 architecture is very close to PC/AT and almost important components for exmaple PIC,PIT,DMA,etc are same. So I feel its not so difficult and I hope I can post patches before long. Thanks, TAKEDA, toshiya Hi, I will stop updating QEMU on Windows web site at least for several months. Because my eye condition becomes not good, I can't see display well. New binaries for Windows will be avialable here by TAKEDA Toshiya. He is developing old Japanese computer emulators. http://www1.interq.or.jp/t-takeda/top.html http://www1.interq.or.jp/~t-takeda/qemu/ Thank you for your help.

[Qemu-devel] [PATCH] Avoid immediate segfault of qemu-i386 on x86_64 host
Hi, I've got a systematic segfault in qemu-i386 ( 0.8.2, 0.9.0 and CVS, but not 0.8.1) on my x86_64. The segfault happens in glibc (2.4) initialization phase, before main : Program received signal SIGSEGV, Segmentation fault. 0x in ?? () (gdb) bt #0 0x in ?? () #1 0x6004a06f in __libc_csu_init () #2 0x2acb8cc1dbce in __libc_start_main (main=0x60005120 main, argc=1, ubp_av=0x7fff1e3192e8, init=0x6004a010 __libc_csu_init, fini=0x2acb8cf39270 initial+16, rtld_fini=0x2acb8c799c30 _dl_fini, stack_end=0x7fff1e3192d8) at libc-start.c:190 #3 0x60004b89 in _start () Basically, it tries to call a function through a function pointer, but this pointer is NULL, hence the segfault. The problems lies in the declaration in linux-user/main.c of __init_array_start variable and friends. Simply removing them do the trick and makes qemu-i386 work nicely. I don't really know why this is here; commit tells RH9 fix - path patch and code comment refers to a probable bug in ld. So I've just changed (in the attached patch) glibc requirement for those variable declarations from glibc=2.3 to glibc == 2.3. I guess it would need additional tests on a more wide variety of hosts.

[Qemu-devel] Partial fix for vvfat + -snapshot
Hi,
the attached patch is an attempt to fix support of
virtual FAT disk images when used with -snapshot
option.
This combination doesn't work anymore in 0.9.0,
and the reason seems to be that code in block.c
that handles -snapshot, completely disregards
the different filename format used for vvfat.
The patch only restores the -hdX fat:dirname
functionality, while additional options such
as :rw:, :floppy: :32: etc, still fail, as some
functions (e.g. path_combine() and path_is_absolute())
only support the fat: prefix.
I'm not sure the fix is correct (I doubt code in
block.c should know specific issues of different
drivers), but it works for my needs, and maybe
somebody else is interested.
The patch is agains 0.9.0.
Best Regards,
Lorenzo
