* x86: remove get_cycles_syncAndi Kleen2008-01-301-52/+8
| | | | | | | | | | | rdtsc is now speculation-safe, so no need for the sync variants of the APIs. [ mingo@elte.hu: removed the nsec_barrier() complication. ] Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: move tsc definitions to were they belongGlauber de Oliveira Costa2008-01-301-0/+4
| | | | | | | | | This patch wipes out the definitions of tsc_disable from processor_32.h and move it to tsc.h, were it belongs Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: split get_cycles_syncGlauber de Oliveira Costa2008-01-301-4/+33
| | | | | | | | | | | | | | This patch splits get_cycles_sync() into __get_cycles_sync(), and the rdtscll part. Paravirt guests cannot issue rdtscl directly, as it involves a function call in vdso area. So, using the __get_cycles_sync() base, we introduce vget_cycles_sync, which then calls the native version of rdtscll. Ideally, however, a guest should define its own clocksource, together with a vread function Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: move tsc related declarationsThomas Gleixner2008-01-301-2/+1
| | | | | | | | tsc has also it's own header file. Nuke the stupid 64 bit ifdef while at it. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: unify timex.h variantsThomas Gleixner2007-10-121-5/+6
| | | | | | | | | | Combine the timex.h variants and move the TSC related code into tsc.h. Move the set_cyc2ns_scale() call into the tsc calibraction code, where it belongs. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com>
* x86_64: Consolidate tsc calibrationThomas Gleixner2007-10-121-0/+4
| | | | | | | | | | | Move the TSC calibration code to tsc.c. Reimplement it so the pm timer can be used as a reference as well.
