[Qemu-devel] about cache model in ARM emulation

2007-10-18 Thread Boy Dfx
Hello I'm a newbie in the use of ARM simulators. I got yesterday a question from my teacher and can't find the answer. I would like to know weather QEMU simulates a cache miss (cache miss holds a penalty in terms of clock cycles or clock cycles counted) for an ARM-type core. >From what I

[Qemu-devel] Debugging x86-64 apps from a 32bit host?

2007-10-18 Thread Simon Peter
Hi, is it possible to debug e.g. a x86-64 Linux kernel running in qemu-system-x86_64 on a 32bit host from that host with GDB? I cross-compiled a version of GDB with x86-64 support, so it can load the debugging symbols from the kernel (which is an ELF64 binary) and attached that to a running qemu-

The easy way to reproduce this is go to "http://landley.net/hg/firmware";, download tip, and "./build.sh powerpc". When it finishes building everything, cd build and "./run-powerpc.sh". What I did is build a new ppc_rom.bin (attached, source code is at http://landley.net/hg/firmware/raw-diff/9
