Marking incomplete. Please confirm this bug if you can reproduce this on Lucid's kvm.

[Bug 500009] Re: floating point exception when Windows NT 4 guest uses its cirrus driver
I am also facing this problem. :-( I used gdb to trace it down. In hw/cirrus_vga.c the exception is hit in cirrus_do_copy: Program received signal SIGFPE, Arithmetic exception. [Switching to Thread 0xb7dbeb90 (LWP 31952)] 0x080aaa85 in cirrus_do_copy (s=0x87474d4, dst=48, src=0, w=2, h=9) at /var/tmp/portage/app-emulation/qemu-kvm-0.12.1.2/work/qemu-kvm-0.12.1.2/hw/cirrus_vga.c:687 687 sx = (src % ABS(s-cirrus_blt_srcpitch)) / depth; (gdb) print s-cirrus_blt_srcpitch $1 = 0 (gdb) print s-vga.gr[0x26] $16 = 0 '\000' (gdb) print s-vga.gr[0x27] $17 = 0 '\000' Perhaps the registers are not properly initialized. I #defined DEBUG_BITBLT and got the following output: rop=0x0e mode=0x00 modeext=0x00 w=2 h=9 dpitch=1 spitch=0 daddr=0x00075300 saddr=0x writemask=0x00 There is only one line of output, so it seems to be the first BLITBLT operation, that failes. This really could be a bad initial register value. Unfortunately, I have no knowledge on the cirrus chip, so I cannot fix this problem. I hope, someone else can figure out a way to fix this. 73, Mario -- floating point exception when Windows NT 4 guest uses its cirrus driver https://bugs.launchpad.net/bugs/59 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
