Hi,
I build qemu with MingW, and after the linking, I find the qemu.exe depends on
some dlls like below, I understand the glib dependencies, but why qemu uses
libffi-6.dll, libiconv-2.dll, libpcre-1.dll libssp-0.dll, libintl-8.dll,
libpixman-1-0.dll, zlib1.dll? I just want to use TCG function an
There is a doc about the API of memory-mapped file on Windows
https://docs.microsoft.com/en-us/previous-versions/ms810613(v=msdn.10)?redirectedfrom=MSDN,
not sure anyone is working on it.
Thanks

Hi,
We are trying to run guest SMP code with qemu icount mode, but based on my
current understanding I don't think we can do that, because with icount
enabled, the multi cpus will be simulated in round-robin way(tcg kick vcpu

I'm running a rtos on qemu_x86 with icount mode enabled, shift value located in

Hi Alex,
If there is something wrong, please tell me. I really like to have some

Hi all,
Recently I'm using Qemu TCG icount mode, from the code I found Qemu timers run
at 1GHz, and for ArmV7M example, there will be conversion factor from qemu
timer to SysTick frequency which will be calculated by NANOSECONDS_PER_SECOND /
SYSCLK_FRQ.
