Hi!=0D
=0D
I would like to publish two debug features which were needed for other stuf=
f=0D
I work on.=0D
=0D
One is the reworked lx-symbols script which now actually works on at least=
=0D
gdb 9.1 (gdb 9.2 was reported to fail to load the debug symbols from the ke=
rnel=0D
for some reason, not related to this patch) and upstream qemu.=0D
=0D
The other feature is the ability to trap all guest exceptions (on SVM for n=
ow)=0D
and see them in kvmtrace prior to potential merge to double/triple fault.=0D
=0D
This can be very useful and I already had to manually patch KVM a few=0D
times for this.=0D
I will, once time permits, implement this feature on Intel as well.=0D
=0D
Best regards,=0D
