I need to stare at the code some more to fully understand it, but it looks like it wouldn't be all that hard to do. Basically just use the interrupt handler to pull all of the data out of the hardware and into a ring buffer in memory, and then a fast taskqueue to process that ring buffer. It would at least answer the question of whether the observed problems are due to ithread latency. And if done right, no locks would be needed in psmintr(). I seemed to have solved my mouse problem: [http://www.mail-archive.com/freebsd-current_at_freebsd.org/msg62824.html]. Solution: I disabled IPCA in the BIOS and the mouse problem went away. Does IPCA have anything to do with ACPI. Yes, I have googled and looked at anandtech forums and had no luck. In disabling IPCA have I disabled ACPI ? - aWReceived on Sun Nov 09 2003 - 18:19:50 UTC
