[Qemu-devel] How to enable DEBUG_IOPORT?
All When I reading the code, i find in the cpu_log_items the CPU_LOG_IOPORT is not enabled since the DEBUD_IOPORT is not defined. I searched the configure file but find no option to enable this. So currently the only way to do this is comment out the macro in ioport.c? -- Wizard
[Qemu-devel] int128_add assumes the result will not exceed 128bits?
All, I am reading this code.
static inline Int128 int128_add(Int128 a, Int128 b){ Int128 r = {
a.lo + b.lo, a.hi + b.hi }; r.hi += (r.lo a.lo) || (r.lo b.lo);
return r;}
This assumes the result r will not exceed 128 bits?--

[Qemu-devel] User Mode Emulation
Hello! I want to run some Intel-Linux-Binaries on a PowerPC-Linux-Machine. Does somebody know how to copy the shared libraries and make them usable by qemu-i386? How to call ldconfig? I want to make a collection of some x86 and ppc-Libraries (like the qemu-gnemul-Package at the qemu-Website), but I found no documentation how to create such a Package. Can somebody help me? Thanks a lot! Chris -- Telefonieren Sie schon oder sparen Sie noch?

[Qemu-devel] qvm86
Hi! I tried to install qvm86 under SuSE Linux Enterprise Server 9 running on a Dual Pentium III with Kernel 2.6.5-7.139-smp. After compiling the module: modprobe qvm86 chmod 666 /dev/qvm86 In /var/log/messages I get the following output: kernel: qvm86: unsupported module, tainting kernel. kernel: qvm86: Module loaded kernel: qvm86: Created device 10.62 When I start qemu, it runs without qvm86 acceleration. I have no idea, why it isn't running with qvm86 on this machine. (Doing the same procedure on a debian system, everything is running perfect!) Thanks for your help!

[Qemu-devel] Time measurement under QEMU
Hello! I need a precise time measurement under QEMU with SLES 9 (Kernel 2.6.8) as host and guest. I synchronize the clock via ntpdate with a ntp-time-server. Then I start heavy load applications. When I execute ntpdate again, I get a negative offset, sometimes a positive offset with more than 1 second. That means that the clock runs slower (or faster) in the guest os. How can I get a time synchronisation between Host- and Guest-OS? I tried the following kernel options at the guest: nosmp noapic nolapic clock=pit But without success :-( Thanks for your help!

[Qemu-devel] Problems with ppc-emulation
Hello! I make different Benchmarks (lmbench / unixbench) on SuSE Linux Enterprise Server 9 (PPC) with SMP-Kernel running on a PowerPC host. The target OS is SLES9 for Intel x86 . With Unixbench 4.1.0 running at the emulated x86-machine I got the following error message: Recursion Test--Tower of Hanoi 1 2 3 awk: /root/unixbench-4.1.0/pgms/index.awk:18: fatal: division by zero attempted This message I get only with the x86-emulation. It doesn't appear when running on a real x86 or a real ppc-machine. Has anybody a solution for this? Best regards, Chris -- Telefonieren Sie schon oder sparen Sie noch?

[Qemu-devel] Re: timing problems
Hi! I checked my QEMU and I found the same Problems. I'm running SLES9 (x86) on an SLES9 (ppc) host. The target clock runs faster(? I've got positive offsets running ntpdate ?) than the host clock. I've tried severel kernel parameters (eg. clock=pit or clock=pmtmr) without any success. The timing problems seem to be not only a problem with Windows XP as guest os.

[Qemu-devel] opc.h and gen-op.h
Hello!
What is the job of the two files gen-op.h and opc.h? They were created by
dyngen -c / -g
I don't understand their content.
opc.h contains something like:
DEF(movl_A0_EAX, 0, 3)
DEF(addl_A0_EAX, 0, 5)
DEF(addl_A0_EAX_s1, 0, 6)
gen-op.h contains:
static inline void gen_op_movl_A0_EAX(void)
{
*gen_opc_ptr++ = INDEX_op_movl_A0_EAX;
}
static inline void gen_op_addl_A0_EAX(void)
{
*gen_opc_ptr++ = INDEX_op_addl_A0_EAX;
}
Can you help me?
Chris
