[Qemu-devel] Debugging registers DR0, DR7 don't work

[Paolo Minazzi]

I'm Paolo Minazzi and I am a new user of QEMU.
I use it to learn protected mode programming in asm.
QEMU is very useful as I can avoid to reset continuosly my PC.

Nevertheless I have a problem.
I have tried to write an asm program to try dr0 and dr7 debugging register.
I have found that this register don' work and I cannot receive the 
excepction 1.
My program instead works fine in a real DOS system.

Does someone indicate me how to enable debugging register with QEMU ?

Thanks in advance
