Actually, as it did receive few tuning, the support is disabled by default, but it can opt-in with the option ADAPTIVE_LOCKMGRS. Due to the nature of lockmgrs, adaptive spinning needs to be selectively enabled for any interested lockmgr. The support is bi-directional, or, in other ways, it will work in both cases if the lock is held in read or write way. In particular, the read path is passible of further tunning using the sysctls debug.lockmgr.retries and debug.lockmgr.loops . Ideally, such sysctls should be axed or compiled out before release. Addictionally note that adaptive spinning doesn't cope well with LK_SLEEPFAIL. The reason is that many (and probabilly all) consumers of LK_SLEEPFAIL are mainly interested in knowing if the interlock was dropped or not in order to reacquire it and re-test initial conditions. This directly interacts with adaptive spinning because lockmgr needs to drop the interlock while spinning in order to avoid a deadlock (further details in the comments inside the patch). Final note: finding someone willing to help on tuning this with relevant workloads would be either very important and appreciated. Tested by: jeff, pho Requested by: many

# On the handling of kernel options
|
|
#
|
|
# All kernel options should be listed in NOTES, with suitable
|
|
# descriptions. Negative options (options that make some code not
|
|
# compile) should be commented out; LINT (generated from NOTES) should
|
|
# compile as much code as possible. Try to structure option-using
|
|
# code so that a single option only switch code on, or only switch
|
|
# code off, to make it possible to have a full compile-test. If
|
|
# necessary, you can check for COMPILING_LINT to get maximum code
|
|
# coverage.
|
|
#
|
|
# All new options shall also be listed in either "conf/options" or
|
|
# "conf/options.<machine>". Options that affect a single source-file
|
|
# <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options
|
|
# that affect multiple files should either go in "opt_global.h" if
|
|
# this is a kernel-wide option (used just about everywhere), or in
|
|
# "opt_<option-name-in-lower-case>.h" if it affects only some files.
|
|
# Note that the effect of listing only an option without a
|
|
# header-file-name in conf/options (and cousins) is that the last
|
|
# convention is followed.
|
|
#
|
|
# This handling scheme is not yet fully implemented.
|
|
#
|
|
#
|
|
# Format of this file:
|
|
# Option name filename
|
|
#
|
|
# If filename is missing, the default is
|
|
# opt_<name-of-option-in-lower-case>.h
