Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

oprofile: Rename variable timeout_jiffies and move to oprofile_files.c This patch renames timeout_jiffies into an oprofile specific name. The macro MULTIPLEXING_TIMER_DEFAULT is changed too. Also, since this variable is controlled using oprofilefs, its definition is moved to oprofile_files.c. Signed-off-by: Robert Richter <robert.richter@amd.com>

int oprofile_set_backtrace(unsigned long depth);
oprofile: Implement performance counter multiplexing The number of hardware counters is limited. The multiplexing feature enables OProfile to gather more events than counters are provided by the hardware. This is realized by switching between events at an user specified time interval. A new file (/dev/oprofile/time_slice) is added for the user to specify the timer interval in ms. If the number of events to profile is higher than the number of hardware counters available, the patch will schedule a work queue that switches the event counter and re-writes the different sets of values into it. The switching mechanism needs to be implemented for each architecture to support multiplexing. This patch only implements AMD CPU support, but multiplexing can be easily extended for other models and architectures. There are follow-on patches that rework parts of this patch.
