* Make VMCompilationPerformance an aggregated profile with defaultVictor Hsieh2022-05-161-13/+4
| | | | | | | | | | | | | | | | | | | | | | The VMCompilationPerformance profile is used to run Isolated Compilation in a Protected VM, normally during the device idle, where relevant APEXes are staged. The original VMCompilationPerformance introduced in aosp/2060891 does not have any specific definition and requires vendors to customize it. This change re-defines it as an aggregated profile with a default set of existing profiles, so that performance can be reasonable by default. This profile may be renamed to a more generic name later, e.g. "SCHED_SP_COMPUTE". Bug: 231437770 Test: Run `composd_cmd test-compile` on a local device. Before: 1m50s +/- 10s (with whatever that's default) After: 1m25s +/- 5s Ignore-AOSP-First: cherry pick from aosp/2097065 Change-Id: Ib8cd65782c818474fb129efbd9ef9a3e23ad1eb3 Merged-In: Ib8cd65782c818474fb129efbd9ef9a3e23ad1eb3

* Migrate the blkio controller to the v2 cgroup hierarchyBart Van Assche2022-03-281-12/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch preserves the following parameter values: * Foreground BFQ weight: 100 * Foreground CFQ group_idle: 0 * Foreground CFQ weight: 1000 * Background BFQ weight: 10 * Background CFQ group_idle: 0 * Background CFQ weight: 200 The foreground BFQ weight in task_profiles.json is the default BFQ weight. From https://www.kernel.org/doc/Documentation/block/bfq-iosched.txt: "weight (namely blkio.bfq.weight or io.bfq-weight): the weight of the group inside its parent. Available values: 1..10000 (default 100). The linear mapping between ioprio and weights, described at the beginning of the tunable section, is still valid, but all weights higher than IOPRIO_BE_NR*10 are mapped to ioprio 0." Bug: 213617178 Test: Booted Android in Cuttlefish and ran the following test: Test: adb -e shell cat /sys/fs/cgroup/*/*/io.bfq.weight | sort | uniq -c Test: 22 default 10 Test: 98 default 100 Change-Id: I7dfa521363a316592852fecce9192708c7a90514 Signed-off-by: Bart Van Assche <bvanassche@google.com>
* Add support for memcg v2 attributesBart Van Assche2022-03-171-2/+29
| | | | | | | | | | | | | | | | | | | | | Some but not all memcg v1 attributes exist in the v2 hierarchy. The following information comes from Shakeel Butt and Kamil Yurtsever, "cgroup v2 migration at Google", Linux Plumbers Conference 2018 ( https://lpc.events/event/2/contributions/204/attachments/143/378/LPC2018-cgroup-v2.pdf ): v1 v2 -------------------------- ---------- memory.limit_in_bytes memory.max memory.soft_limit_in_bytes memory.low Add support for cgroup attributes that have different names in the v1 and v2 hierarchies. Also add those memcg attributes that are used in lmkd. Bug: 213617178 Test: Tested lmkd with v1 and v2 memcg.

| | | | | | | | | Create a new group for dex2oat in cpu cgroup, which is dedicated for dex2oat processes. Also modify task profiles for this change. Bug: 201223712 Test: dex2oat group created Change-Id: Ic61f4b8a64d01c03549b680970805e12b9ce4fcc
* task_profiles.json: add taskprofile for dex2oat boot_complete policyWei Wang2021-07-121-1/+5
| | | | | | | | | | | | | | | Since installation time is also critical and sometime we want a finer control on its behavior for vendor. Instead of set dex2oat to background group, add a new task profile. The default policy is to mirror SP_BACKGROUND to be compatible with legacy devices.

| | | | | | | | | | | | | In some platforms, setting a different cpuset (or remove it) and/or uclamp setting is beneficial to both performance and power.
