[Qemu-devel] A question about QEMU performance
Hi all,This is my question:If I run qemu for i386 without kqemu it uses soft-mmu, so it operates as another architetture as ppc or mips right?So... are the performace of qemu the same if I use i386 or mips or something change deeply? Example: if I run the same program on i386 emulation without kqemu or on mips are the performance circa the same?ThanksAle ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel

It's probably all relative to the speed of the cpu, host OS, compiler optimizations and trans cpu data transforms, as to how well the emulated system performs. ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
[Qemu-devel] qemu arm eabi (armel)
Does anyone have qemu running in user emulation with arm eabi, (armel), traps? I can get qemu-system booting an armel system. And I can get qemu-user running with the codesourcery gcc-3 eabi libc's, (ie, the ones with the codesourcery kernel call shims), but I haven't gotten it working yet with eabi kernel calls in user mode. Should this be expected to work in 0.8.2? --rich ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel

Re: [Qemu-devel] qemu arm eabi (armel)
Ok, then I'm confused because I'm seeing dumps just trying to run a null program. Unless there's NPTL setup stuff in crt0, I can't guess what might be going on yet. This same null binary runs on a qemu-system with suitable rootfs kernel. --rich [EMAIL PROTECTED] ./qemu-arm --version qemu-arm version 0.8.2, Copyright (c) 2003-2005 Fabrice Bellard [...] [EMAIL PROTECTED] ./qemu-arm ./null qemu: uncaught target signal 11 (Segmentation fault) - exiting ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel

Unless there's NPTL setup stuff in crt0, I can't guess what might be going on yet. This same null binary runs on a qemu-system with suitable rootfs kernel. The glibc startup code contains TLS initialisation that will fail on unpatched qemu. If you have applied the TLS patch there are a couple of other things that could cause problems: - Make sure it's picking up the correct target shared libraries (or link your test application statically). - Try configuring qemu with --static. The default (building qemu as a shared library) seems to cause strange problems on many systems. - Make sure uname -r reports at least 2.6.16 (qemu can lie for you).

[Qemu-devel] Installing linux from multiple installation CDs
Hi, I am trying to install linux as a guest OS on Windows using QEMU. How do I install linux from multiple installation cds? Thanks! Arini ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel

Arini Use the qemu monitor to change the disc in qemu's emulated cdrom drive. ie: Access the qemu monitor (ctrl-alt-2). (qemu) eject cdrom (qemu) change cdrom //./d: D is the drive letter associated with the physical cdrom. If it is an iso then use the full filename of the iso.
