BDRV_O_FILE is only used to communicate between bdrv_file_open and bdrv_open.
It affects two things: first bdrv_open only searches for protocols using
find_protocol instead of all image formats and host drivers. We can easily
move that to the caller and pass the found driver to bdrv_open.

CONFIG_USER_ONLY kinda sorta tries to manage the distinction between
qemu memory and guest memory. This can be seen in the PAGE_RESERVED

The Problem:
CONFIG_USER_ONLY kinda sorta tries to manage the distinction between
qemu memory and guest memory. This can be seen in the PAGE_RESERVED
frobbing and qemu_malloc etc. However, it doesn't handle random malloc
I need the PC and the executated instruction to extract a complete trace of the
execution in a file.
I found since the translation block is cached the -d in_asm option with not
output a complete execution trace. Only when the TB is cached is logged.
What does -singlestep means?
thanks,

These duplicates simply double the amount of output produced with no
extra information emitted.

Fine by me, though i'm maintaining none
The dirty and non-dirty pages are checked one by one. When most of the memory
is not dirty, checking the dirty and non-dirty pages by multiple page size
should be much faster than checking them one by one. We introduced bit-based
phys_ram_dirty for VGA, CODE, MIGRATION, MASTER, and
Modifies ram_save_block() and ram_save_remaining() to use
cpu_physical_memory_get_dirty_range() to check multiple dirty and non-dirty
pages at once.

I think the correct way to get the full instruction trace on a MIPS
emulated processor is:
the way you describe is slow because you are constantly re-generating the
TBs. The best way to do this is to add your instrumentation to the TBs.
I have code that does that for a recent version of

There might be cases where a few bytes would have been sent out to char

to char devs are only -1, indicating an error, or the complete length

My question was not an april fools' day joke. You are developers and answer to
this question may seem obvious to you, but it is not obvious to me. Please
answer. Thanks
Hi,
I always thought that the stop command provided by the monitor
interface would pause the VM completely, but it doesnt seem so?
I checked this by issuing the stop command on my VM, and noted its
clock. Few minutes later, I resumed the VM (with cont command). The
clock is immediately updated
Please send in any agenda items you are interested in covering.
thanks,
