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,
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

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?
uint8_t dummy[(1 CPU_TLB_ENTRY_BITS) -
on already translated code.
This patch fixes the problem by flushing all the TB to force new code
generation.

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).
Thanks,
