During load balance, the scheduler evaluates the number of tasks that a group
of CPUs can handle. The current method assumes that tasks have a fix load of
SCHED_LOAD_SCALE and CPUs have a default capacity of SCHED_CAPACITY_SCALE.
This assumption generates wrong decision by creating ghost cores or by
removing real ones when the original capacity of CPUs is different from the
default SCHED_CAPACITY_SCALE. We don't try anymore to evaluate the number of
available cores based on the group_capacity but instead we evaluate the usage
of a group and compare it with its capacity
This patchset mainly replaces the old capacity method by a new one and has kept
the policy almost unchanged whereas we could certainly take advantage of this
new statistic in several other places of the load balance.
The utilization_avg_contrib is based on the current implementation of the
load avg tracking. I also have a version of the utilization_avg_contrib that
is based on the new implementation proposal [1] but haven't provide the patches
and results as [1] is still under review. I can provide change above [1] to
change how utilization_avg_contrib is computed and adapt to new mecanism.
Change since V5
- remove patches that have been merged since v5 : patches 01, 02, 03, 04, 05, 07
- update commit log and add more details on the purpose of the patches
- fix/remove useless code with the rebase on patchset [2]
- remove capacity_orig in sched_group_capacity as it is not used
- move code in the right patch
- add some helper function to factorize code
Change since V4
- rebase to manage conflicts with changes in selection of busiest group [4]
Change since V3:
- add usage_avg_contrib statistic which sums the running time of tasks on a rq
- use usage_avg_contrib instead of runnable_avg_sum for cpu_utilization
- fix replacement power by capacity
- update some comments
Change since V2:
- rebase on top of capacity renaming
- fix wake_affine statistic update
- rework nohz_kick_needed
- optimize the active migration of a task from CPU with reduced capacity
- rename group_activity by group_utilization and remove unused total_utilization
- repair SD_PREFER_SIBLING and use it for SMT level
- reorder patchset to gather patches with same topics
Change since V1:
- add 3 fixes
- correct some commit messages
- replace capacity computation by activity
- take into account current cpu capacity

arm64-allnoconfig
arm-multi_v7_defconfig
x86_64-defconfig
This patchset removes some single-platform compatibility tricks related
to DEBUG_LL and, as a result, allows multi_v7_defconfig derived builds
to enable DEBUG_LL. Currently the user selected kbuild setting is
ignored and the PL01X's DEBUG_LL stub is silently selected instead. This
is a pain if your hardware doesn't have this cell, not least because it
takes a little time to figure out that kbuild built the wrong code.
Warning:
silentoldconfig on PL011 single platforms will result in DEBUG_LL
being directed at ICEDCC rather than PL011. This should only
affect silentoldconfig since oldconfig prompts and the defconfigs have
been updated to avoid this problem.
Changes since v12:
- v11 spuriously missed out changes from v10 and v11 (it was incorrectly
derived from v9). All changes have been reinstated after thorough
review of the diff between v13 and v11 (many thanks to Aaro Koskinen).
- Merged the changes to 8250 related changes to defconfig files into
a single patch (Arnd Bergmann).
Changes since v11:
- Fixed sort order of Kconfig symbols (review of Russell King)
- Reviewed all defconfigs for the selection of DEBUG_UART_NONE. All
identified have 8250-based UARTs and are switched to DEBUG_LL_UART_8250
(review of Arnd Bergmann).
- Fixed regression in the netx macros (bad setting of \rp and \rv.
- Rebased on latest mainline (v3.18-rc1). Note that two patches from v11
were merged upstream and are no longer included here.
- Added a trivial fix to the defaults list for DEBUG_UART_PHYS which came
to my attention as a merge conflict.
Changes since v10:
- Fixed typos in the omap1 config help texts (review of Aaro Koskinen).
Changes since v9:
- Removed a spuriously introduced (and unused) config variable from
the netx patch (review of Paul Bolle).
- Fix netx macro to ensure \rv is correctly initialized.
- Rebased on v3.17rc4.
Changes since v8:
- Regenerated patch series with --find-renames to properly track code
movement.
Changes since v7:
- Killed DEBUG_LL_UART_NONE completely and migrated over the four remaining
platforms that relied on this (Arnd Bergmann, Russell King). This
fixes some problems with oldconfig builds.
- Rebased on latest mainline (v3.17rc1).
Changes since v6:
- Removed a patch to limit DEBUG_LL_UART_NONE to platforms that support
it because it almost time to drop DEBUG_LL_UART_NONE anyway (only
four platforms still use it).
- Rebased on latest mainline (v3.16rc3).
Changes since v5:
- Shortened the list of platforms that can select DEBUG_LL_UART_NONE
(changes Arnd Bergmann)
- Rebased on latest mainline (v3.15rc7).
Changes since v4:
- Rebased to latest mainline (and tested again). No functional changes.
Changes since v3:
- Converted from a single patch to a series.
- Tested defconfig builds of all impacted platforms.
Changes since v2:
- Switch from def_bool to bool (thanks Russell King)
Changes since v1:
- Remove pointless single platform support (thanks Arnd Bergmann)
