Re: [Qemu-devel] Two quick requests.
If you really want to do this, do it properly. Make it an error to use a ro image if the user [implicitly] requests rw access. If there's no middle ground between silently misbehave and refuse to start if anything _might_ be wrong, then why does current qemu warn about the 1024 hz thing? Even at 1024Hz qemu still misbehaves, especially on heavily loaded hosts. 1024Hz is sufficient for most common operating systems most of the time, but many will run happily without it. e.g. many linux kernels only need 100 or 250Hz.

Hi.
With the attached patch I am able to use Kodak Advantix FD 300 APS

I tried to separate the linux dependencies with #ifdef __linux__, but
can not test this does not break compilation for other ports of qemu.
I don't understand why you need a #ifdef __linux__ in parallel.c.
Normally, the qemu character device should suffice to do the
appropriate abstraction.
...
I am too new with qemu to say how to develop the qemu character device
abstraction for these requirements.
Thanks for the offline tip, Fabrice.
Here is a new patch for EPP support. This time all linux code is in
ioctls. I hope you find it good enough.

[Qemu-devel] PATCH: updated solaris tap patch
This patch against current CVS is an update of the previously posted Solaris
TAP patch. This small change fixes a large performance problem with
inbound packets (scp, ftp). The author found that some packets were
concatenated, which was the reason for the poor performance. This patch
fixes the handling of inbound packets and the performance problem.
Using the tap to the localhost, downloaded several 50MB files
(1.6MB/sec-4.0MB/sec)
and using the bridge, downloaded a 60MB file from an external host and
got 649 KB/sec.
Thanks again to Sittichai Palingsong for the quick fix.

Alexander Voropay a écrit : Hi! This patch replaces hardcoded MIPS Malta bootloader with soft version. This preserves ROM area clean. Also it initializes MIPS $sp register as YAMON does. Well this patch looks basically ok, except that - It's not possible anymore for an OS to jmp at 0x1f00 to reboot (is it really necessary to simulate that). - It's not possible anymore to add some code to initialize the GT64120 BARs the way YAMON does (and from our discussion on IRC, it looks like this is necessary). It is also possible to modify the GT64120 code directly, but that can mess a possible bootloader (when one is available). So I suggest to hold this patch, at least until we have solved the GT64120 BARs problem. -- .''`.
