x86: move vgetcpu mode probing to cpu detection

2008-10-13T08:21:49Z

Take it out of time initialization and move it to cpu detection time. Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar

x86: wrap MCA_bus test around an ifdef

2008-10-13T08:21:47Z

Only test for MCA_bus if support for MCA is compiled in. Also, for x86_64, write the code inside the conditional for consistency with i386. It won't bite us, since it'll probably never select CONFIG_MCA anyway. Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar

x86: rename timer_event_interrupt to timer_interrupt

x86: use user_mode_vm instead of user_mode

2008-10-13T08:21:34Z

For x86_64, it does not really matter. But makes the code equal to i386. Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar

x86: merge tsc_init and clocksource code

2008-07-09T05:43:27Z

Unify the clocksource code. Unify the tsc_init code. Signed-off-by: Alok N Kataria Signed-off-by: Dan Hecht Cc: Dan Hecht Signed-off-by: Ingo Molnar

x86: merge tsc calibration

2008-07-09T05:43:25Z

Merge the tsc calibration code for the 32bit and 64bit kernel. The paravirtualized calculate_cpu_khz for 64bit now points to the correct tsc_calibrate code as in 32bit. Original native_calculate_cpu_khz for 64 bit is now called as calibrate_cpu. Also moved the recalibrate_cpu_khz function in the common file. Note that this function is called only from powernow K7 cpu freq driver. Signed-off-by: Alok N Kataria Signed-off-by: Dan Hecht Cc: Dan Hecht Signed-off-by: Ingo Molnar

x86: use cpu_khz for loops_per_jiffy calculation, cleanup

2008-06-24T11:53:46Z

As suggested by Ingo, remove all references to tsc from init/calibrate.c TSC is x86 specific, and using tsc in variable names in a generic file should be avoided. lpj_tsc is now called lpj_fine, since it is related to fine tuning of lpj value. Also tsc_rate_* is called timer_rate_* Signed-off-by: Alok N Kataria Cc: Arjan van de Ven Cc: Daniel Hecht Cc: Tim Mann Cc: Zach Amsden Cc: Sahil Rihan Signed-off-by: Ingo Molnar

x86: use cpu_khz for loops_per_jiffy calculation

2008-06-23T20:51:33Z

On the x86 platform we can use the value of tsc_khz computed during tsc calibration to calculate the loops_per_jiffy value. Its very important to keep the error in lpj values to minimum as any error in that may result in kernel panic in check_timer. In virtualization environment, On a highly overloaded host the guest delay calibration may sometimes result in errors beyond the ~50% that timer_irq_works can handle, resulting in the guest panicking. Does some formating changes to lpj_setup code to now have a single printk to print the bogomips value. We do this only for the boot processor because the AP's can have different base frequencies or the BIOS might boot a AP at a different frequency.
