2021-05-06sched,doc: sched_debug_verbose cmdline should be sched_verboseBarry Song
The cmdline should include sched_verbose but not sched_debug_verbose as sched_debug_verbose is only the variant name in code.

2021-04-17sched/debug: Rename the sched_debug parameter to sched_verbosePeter Zijlstra
CONFIG_SCHED_DEBUG is the build-time Kconfig knob, the boot param sched_debug and the /debug/sched/debug_enabled knobs control the sched_debug_enabled variable, but what they really do is make SCHED_DEBUG more verbose, so rename the lot. Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>
2020-11-19Documentation: scheduler: fix information on arch SD flags, sched_domain and ↵Barry Song
sched_debug This document seems to be out of date for many, many years. Even it has misspelled from the first day. ARCH_HASH_SCHED_TUNE should be ARCH_HAS_SCHED_TUNE ARCH_HASH_SCHED_DOMAIN should be ARCH_HAS_SCHED_DOMAIN Since v2.6.14, kernel completely deleted the relevant code and even arch_init_sched_domains() was deleted. Right now, kernel is asking architectures to call set_sched_topology() to override the default sched domains. On the other hand, to print the schedule debug information, users need to set sched_debug cmdline or enable it by sysfs entry. So this patch also adds the description for sched_debug.

2020-04-21Documentation: scheduler: fix outdated information on sched groupsAdrian Freund
The documentation claims that two sched groups must not overlap. This is no longer true, as overlapping sched groups are used on NUMA systems. This change has been introduced by commit e3589f6c81e47 and was documented by an in-code comment in commit 35a566e6e8a18.

2019-06-14docs: scheduler: convert docs to ReST and rename to *.rstMauro Carvalho Chehab
In order to prepare to add them to the Kernel API book, convert the files to ReST format. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
