[Qemu-devel] Lament: 0.6 breaks usermode

[Qemu-devel] Lament: 0.6 breaks usermode

[Wim Vanderbauwhede]

I am disappointed with the direction qemu has taken.

Up to 0.5.5, I had rather decent usermode functionality with qemu-i386
on linux/PPC: Acrobat reader, Firefox with flash, even Wine after a
fashion. I was happy.

With version 0.6 up to and including the most recent snapshot, it's
gone: lots of "free(): invalid pointer 0x....!" , segfaults and no
functionality. 
I had hoped the user mode stuff would get better not worse.

FYI, I use:

kernel 2.6.6-2mdk
gcc  3.4.1 
glibc 2.3.3
binutils-2.15.90.0.3-1mdk

Also FYI, I got a compilation error in 0.6.0 due to an error in
cpu-exec.c:

     struct ucontext *uc = puc;
     unsigned long pc;

It's still there in the latest snapshot.

As fabrice mentioned before, the "system wide" approach is now taking a higher 
priority due to people want to use this more then user level mode..

I'm sure that if someone will submit some patches to fix the errors, Fabrice 
will commit it (I can host those patches if anyone wants, just CC me with 
those patches)..

Thanks,
Hetz

Hetz, thanks for your support.

But I think it unlikely that someone will submit patches to fix
usermode, as it seems none of the developers is interested. 
I'm just a user, fixing some compilation errors is the most I can do.
