1. Periodic Time Sync b/w driver and FW. Periodic time sync sets the time of the FW to be the same as the time of the Driver (HOST). With Existing driver, time stamp synchronization occurs only during Driver load and controller reset. With Patch1 - Period time sync implementation facilitates driver to sync time stamp periodically with IO_UNIT_CONTROL request. 2. Persistent support for diag triggers. mpt3sas driver support Automatic Firmware Diagnostic Buffer feature. As part of this feature, drivers provide Trigger from IOCTL and SysFS interface using which user can set/get/ clear triggers. Driver releases Diagnostic buffer registered with firmware if any trigger gets hit. The triggers set by user are not persistent across system reboots. As a result triggers set by user will be lost after each reboot. This patch set uses Persistent Trigger Pages so that triggers set by user will not be lost across system reboots.
