if you like waiting 2 minutes to move the mouse 1 pixel in a fullscreen game (not to mention the 4-10 hours it takes to switch from desktop to the game) then I may put something like that in
for a faster speed it'd most likely be intel cpu's only though (perhaps specific branches of intel cpu's at that), and might be 32-bit only, or require dbvm, so also a limited number of intel cpu's and only those with certified bioses (some bioses have fucked usb smm routines)
Info for myself IF i decide to add it
Code: |
IA32_DEBUGCTL : Bits to set
BTF (single-step on branches) flag (bit 1) or LBR (system wide)
BTS (branch trace store) flag (bit 7)
BTINT (branch trace interrupt) flag (bit 8)
BTS_OFF_OS (branch trace off in privileged code) flag (bit 9)
Might be dbvm only due to taskswitch detection enabling/disabling logging
the log on Trace flag might be used, but will rape normal debuggers in the system

here's a picture showing the current progress
The selective part isn't implemented yet as the system I'm testing on doesn't have the select msr ability

Yup it's dbvm only.
Unless you're in 32-bit and hook the windows taskswitch routine and enable the debug msr on taskswitch to a thread in the specific process, and disable when going to a thread not in the target process. (and in vista+ you may have to mess with the debugger as well as vista+ will interfere)
