Hi, i'm trying to write a simple driver (on windows 7 x64) that hook general Protection Exception from idt, i would to know why when i add to my isr a call to an API (like KdPrint) the system hang, i saw that on windows xp must be corrected the value of segment registers, what i need to do on win7?
my goal is to add to my isr a dpc routine that does some functions, it is possible?
thank's for attention and sorry my bad English.
I think I found the problem, if I add the SWAPGS instruction at the beginning and at the end of my ISR the DPC routine runs fine but now I have the problem that once that the ISR was performed the CPU is in x86 mode
