when testing in qemu, launching each ap became slower and slower because all the ap's where spinning in syncclock() waiting for cpu0 to update its mach0->tscticks, which happens only much later after all cpu's have been started up. now we wait for each cpu to do its timer callibration and manually update our tscticks while we wait and each cpu will not spin but halt while waiting for active.thunderbirdsarego. this reduces the system load and noise for timer callibration and makes the mp startup linear with regard to the number of cores. |
