Hi, my little qemu project (I name it qemu-xp and will report on it later) has reached it's starting point. Unfortunately these "preparations" are so interesting they might be helpfull for users. Such an important but trivial thing is to make the clock in windows go right (now also with speed-step).
Currently I still run tests with win2003. My VM runs as a batch on
a server using an Atlon 3000. Access to that VM is via win terminal
server and rdesktop as client. This configuration runs better than
expected. Next test will be to let the WUS server run on this VM.
As you know one of the key things was async IO and async SDL (other-
wise windows does not run smootly). Another one are "optimisations" in
timer handling. The qemu-xp project would add a lot of code to make
qemu easier (and a little faster) to use in production environments.
So I decided to "refactor" the code while I was programming new stuff.
This currently causes problems in submitting reasonable patches. So
here is some source code that might be needed for my patches.
(1) osdep.c|h This layer seems to be required to prevent TLS and
mmap usage from glib. The code was completely unreadable due
to too many #ifdef - I added comments and indentations. Also
some malloc stuff was migrated to #defines in order to avoid
trivial wrapper functions (they are still there and can be ena-
bled). A new function qemu_mresize() was added. It is intended
for dynamic arrays - and dyn arrays are faster than malloc'ed
lists under some circumstances in systems that run under high
memory pressure (VMs always will).
(2) tools.c is a new file and will collect all the little helpers
that are scattered through qemu. I would move helper functions
and the typically #ifdef'ed stuff like Wait(n)/usleep(n*1000)
into this file. Currently qemu_set_errno() may find your atten-
tion.
To say it again: Currently I did some preparations for the real
work, but the real work has not yet begun!
Yours Juergen
