| 2008-12-31 | [PATCH] fast vdso implementation for CLOCK_THREAD_CPUTIME_ID | Martin Schwidefsky | |
| The extract cpu time instruction (ectg) instruction allows the user process to get the current thread cputime without calling into the kernel. The code that uses the instruction needs to switch to the access registers mode to get access to the per-cpu info page that contains the two base values that are needed to calculate the current cputime from the CPU timer with the ectg instruction.
