Justin T. Gibbs 5fb0f52712 Improve sync recovery algorithm: ... o Remove PSM_SYNCERR_THRESHOLD1. This value specified how many sync errors were required before the mouse is re-initialised. Re-initialisation is now done after (packetsize * 2) sync errors as things aren't likely to improve after that. o Reset lastinputerror when re-initialisation occurs. We don't want to continue to drop data after re-initialisation. o Count the number of failed packets independently of the syncerrors statistic. syncerrors is useful for recovering sync within a single packet. pkterrors allows us to detect when the mouse changes its packet mode due to some external event (e.g. KVM switch). o Reinitialize the mouse if we see more than psmpkterrthresh errors during the validation period. The validation period begins as soon as a sync error is detected and continues until psmerrsecs/msecs time has elapsed. The defaults for these two values force a reset if we see two packet errors in a 2 second period. This allows rapid detection of packet framing errors caused by the mouse changing packet modes. o Export psmpkterrthresh as a sysctl o Export psmloglevel as a sysctl. o Enable more debugging code to be enabled at runtime via psmloglevel. o Simplify verbose conditioned loging by using a VLOG macro. o Add several comments describing the sync recovery algorithm of this driver.
