Hello,
I tried the cvs version from about a week ago with the latest kqemu driver, but
the network problem still exists. I am using:
qemu -net nic -net tap,ifname=my-tap
under Win2k with a Gentoo guest. The network throughput is about 20 MB ( per
Minute ! ).
When I use qemu 0.7.2 with the tap

Hello,
this is to inform you that I have extended the QEMU ARM emulation to
support coprocessor 14, as implemented in the Embedded ICE version
0b0010. This coprocessor implements the debug communications channel,
which is usually used to communicate via a JTAG-based hardware debugger.

There's a slippery slope both ways. If you assume vital parts of your system

Paul, thanks for the note.
In my case, the guest CPU is idle. The host CPU utilization is only 5

Hi Ken,
I'm attaching a pretty old patch I made (from the 0.7.1 days), which did

some quick hints on how to merge the 2. Basically it fills the select
Hi Ken,
please disregard my last mail on this... here's a current patch against

Hi,
I made a little patch of timer/clock for Linux host. It always trys to use

getitimer doesn't report a correct interval value.
