3 years agokernel - Add TPS balancing mode to scsi_da (da* disks)

kernel - Add TPS balancing mode to scsi_da (da* disks)

* This feature brings write tps down to match read tps when both are
  pending.  Normally both read and write I/Os get at least a few tags,
  but because write I/O is buffered by devices, even giving it one tag
  can complete destroy read performance.

  To accomplish this the feature monitors approximate TPS using a counter
  with exponential decay and will temporarily sets write openings in the
  device queue to zero.

* SSDs usually do a better job on their own, but this feature won't hurt
  so we do not distinguish between HDDs and SSDs.

* New sysctls for this feature (feature is enabled by default):

  kern.cam.da.balance_enable 1 (0=disable, 1=enable)
  kern.cam.da.balance_ratio 100 (read:write ratio, 1:1 is 100)
  kern.cam.da.balance_debug 0 (log to console each second)

  You can adjust the read:write tps ratio as desired.  For example,
  the value 200 will adjust the ratio to 2:1.

  "pvplw" indefinitely.  The timing window is very short and the
  race is fairly difficult to reproduce.

* For this race to occur, more than one interaction must take
  place on other cpus against the placemarker being waited on
  by pv_placemarker_wait().  It takes multiple interactions for
  the WAKEUP bit to be lost.

  The first interaction can clear the WAKEUP bit and issue a
  wakeup() before we manage to interlock.  The second interaction
  can then reserve the placemarker so our conditional fails and

  sufficient due to cuteness on my part in overloading the WAKEUP
  bit on top of NOPLACEMARK (NOPLACEMARK is '-1').

* The solution is to both properly order the interlock AND use
  a cmpset loop to prevent accidently setting the WAKEUP bit on
  a marker that has already been released.
