Hello,
I am looking at how the main thread interrupts TCG thread. Inside
cpu-exec.c, in function cpu_tb_exec(), I can see that it executes one TB,
and when this is over, it can check for events from other threads (like
main thread). This is the reason why TCG thread can be interrupted.

Hi,
In target-arm/helper-a64.c, there is a call to crc32().
I searched everywhere in the source, but still cannot find this function

Any hint where this function is, please?
Thanks.
Hi,
I am wondering how the timer interrupt works in softmmu TCG mode (on X86)?
In general, we would have timer & code execution run in parallel, then once
in a while, the timer would interrupt the code execution to switch it out
to execute the timer interrupt.

Hi,
I am trying to find the definition of cpu_ldub_code() in Softmmu mode.
However, the only thing I can find is like this in include/exec/cpu_ldst.h:

Unfortunately, this is only for Usermode (CONFIG_USER_ONLY), so still I

Hi,
Anybody please help me on this dump-guest-memory command? How does the
virtual memory map to the dumped file?
For example, if x86 register RIP points to 0x12345, how does that map to
the dump file? Meaning how can I find where this address 0x12345 in the

The same OS boots fine in physical machine, and this OS comes with no

Hi,
Function regs_to_env() in target-i386/exec.h has a code like below:
...
#ifdef reg_EAX
env->regs[R_EAX] = EAX
#endif
...
However, elsewhere we have EAX defined as:
#define EAX (env->regs[R_EAX])
This means effectively, we have code like:
env->regs[R_EAX] = env->regs[R_EAX];

Could you compare the performance of TCG and TCI? I suppose th
This patch avoids handling write watchpoints on read-only memory access.
It also breaks the searching loop for watchpoint once the setup for
handling watchpoint later is done.

Hi,
I found that many Armadillo-packed programs fail to work on Qemu (but
is OK to run on KVM). Something must be wrong on the way we emulate
some instructions.
Anybody experiences this problem, and know where the issue is?
Thanks,
Jun

Hi,
In x86, GETPC() is implemented as below:
# define GETPC() ((void *)((unsigned long)__builtin_return_address(0) - 1))
As I understand, it gets the returned address on the stack, then
subtract 1 to get back to the above address.
Imagine we have code like this (pseudo asm code):
CALL
.

Hi,
I am wondering if is it possible to have multiple monitor interfaces
at the same time? If so, how can we open more than one?
This might be useful for something like libvirt, so while we leave one
monitor port for libvirt, we can still access to another one to
control Qemu?
Thanks,
J

It is not necessary to continue searching for watchpoint when we
already found one and setup for handling watchpoint in a search loop
in tlb_set_page().
This patch breaks that search loop on then.

Hi,
I am trying to debug a VM using gdb. I connected gdb to Qemu (latest
code from git repo), and issued below command:
...

The idea is to catch the write access to address 0x77f44cd8.
But after the "c" command, I saw that the window title of my VM

Hi,
I want to compile Qemu on Windows (then run it there). Is there any
instruction on how to do that?
(I googled around, to no avail)
Many thanks,

Thank you for the explanation of this code.
Qemu has a command named singlestep, which reduces the translated code
block to be only one instruction.
This new patch flushes TBs both when singlestep is on and off.

Hi,
I find the way we calculate the dummy field in CPUTLBEntry funny. What
is the point of having:
((-sizeof(target_ulong) * 3) & (sizeof(unsigned long) - 1))
in its size? Why shouldnt it be more simple, like below?

Hi,
I am writing a small tool to trace all the activities that write to an
area of (virtual) memory in Qemu.
I am currently doing that by putting my code at the top of the below
macro in softmmu_header.h

However, it seems I still miss some

Hi,
In the TLB entry, why do we need to maintain separately addr_read,
addr_write and addr_code? Is it impossible to have only one for all
the purposes?
As far as I can see in tlb_set_page(), these fields are mutually
exclusive, as they either enable or get invalid value (-1).

on already translated code.
This patch fixes the problem by flushing all the TB to force new code
generation.
