  "message": "[PATCH] ipmi: add timer thread\n\nWe must poll for responses to commands when interrupts aren\u0027t in use.  The\ndefault poll interval is based on using a kernel timer, which varies with HZ.\nFor character-based interfaces like KCS and SMIC though, that can be way too\nslow (\u003e15 minutes to flash a new firmware with KCS, \u003e20 seconds to retrieve\nthe sensor list).\n\nThis creates a low-priority kernel thread to poll more often.  If the state\nmachine is idle, so is the kernel thread.  But if there\u0027s an active command,\nit polls quite rapidly.  This decrease a firmware flash time from 15 minutes\nto 1.5 minutes, and the sensor list time to 4.5 seconds, on a Dell PowerEdge\nx8x system.\n\nThe timer-based polling remains, to ensure some amount of responsiveness even\nunder high user process CPU load.\n\nChecking for a stopped timer at rmmod now uses atomics and del_timer_sync() to\nensure safe stoppage.\n\nSigned-off-by: Matt Domsch \u003cMatt_Domsch@dell.com\u003e\nSigned-off-by: Corey Minyard \u003cminyard@acm.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
