* 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 Assche2022-03-282-19/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Assche2022-03-172-4/+32
| | | | | | | | | | | | | | | | | | | | | 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.

* Add support for optional cgroup attributesBart Van Assche2022-03-161-1/+2
| | | | | | | | | | | Cgroup attributes like io.weight or io.bfq.weight only exist if the corresponding I/O scheduler has been loaded. Hence add support for ignoring failures to write to a cgroup attribute that does not exist. Bug: 213617178 Test: This patch has been tested in combination with patch "Migrate the blkio controller to the cgroup v2 hierarchy".

* Fix cgroup directory permissionsBart Van Assche2022-03-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | Cgroup attributes are set from three different contexts: (1) From the process that creates the cgroup directories. These processes are /system/bin/init, zygote and zygote64. (2) From the created process. Some but not all created processes have user ID and/or group ID 'system'. (3) The system_server process modifies certain cgroup attributes from other processes. Allow all processes from the system group, including system_server, to modify cgroup attributes from other processes. As one can see in init.rc, that file includes commands for granting the system group write permission for blkcg attributes. See also https://cs.android.com/android/platform/superproject/+/master:system/core/rootdir/init.rc Bug: 213617178 Test: Verified in the Cuttlefish emulator that this patch makes the Test: io.bfq.weight write errors disappear from logcat.

* libprocessgroup: introduce optional attribute for cgroup controllersSuren Baghdasaryan2021-03-113-3/+6
| | | | | | | | | | | | | | | | | | | | | Memory cgroup controller is not used by high-end Android devices and is disabled in Android kernels 5.10+, however Android Go devices still require this controller. Similarly schedtune controller is being replaced with cpu controller's utilclamp feature, however some devices are using older kernels which only support schedtune. To prevent spamming logcat with errors we need a way to mark a controller optional in such cases without removing it from cgroups.json file. Introduce "Optional" attribute to cgroup controller's cgroups.json description to accomodate these cases. When an optional controller fails to mount due to lack of support in the kernel it will log an informational message without generating further errors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current per-API level task profiles replace the latest task profiles rather than overriding the diffs. This poses an issue when a new feature is added which is applicable to older devices as well we have to change all per-API level profiles. Change the per-API task profile support to load the latest task profiles first and then override with per-API task profiles, similar to how vendor task profiles override system task profiles. This minimizes the changes we need to do to the per-API level task profiles going forward and is more consistent with how vendor task profiles work.

| | | | | | | | | | | | | | | | | | | | Add system-background cgroup hierarchy for uclamp and cpu bandwidth tuning. Bug: 170507876 Bug: 171740453 Test: boot and check cgroup Change-Id: I41745e7b3ac5c1d7ea7dd77f5db39c6895047446
* | libprocessgroup: uid/pid hierarchy for cgroup v2Marco Ballesio2020-12-022-12/+0
|/ | | | | | | | | | | | | | Enable the uid/pid hierarchy for all groups when using cgroup v2. Mount the hierarchy under the cgroup v2 root. Make sure that all files under the hierarchy are accessible by the system user. Test: booted the device, tested the freezer cgroup, manually verified the working of the freezer from logs and by checking statuses of processes. Bug: 168907513 Test: Booted the device, verified no regressions on process group access Change-Id: I73f3e767d377902af6e12facb503b9136fb39e08
* libprocessgroup: Support per-API level task profilesSuren Baghdasaryan2020-11-237-0/+2104
| | | | | | | | | | | | | | | | | | | When task profiles changes happen, devices released under older API levels might have to use the same profiles as before. This might be due to for missing kernel features or some other reasons. Add support for per-API task profiles to accommodate this scenario. With this mechanism when ro.product.first_api_level is non-empty, the system looks for /system/etc/profiles/task_profiles_<api level>.json file and uses it if it exists. If ro.product.first_api_level is not defined or per-API task profiles file does not exist the system falls back to the default /system/etc/profiles/task_profiles.json file. As before, these task profiles can be competely overwritten using /vendor/etc/task_profiles.json if needed.

| | | | | | | | | | Put tasks into a subgroup so that we can set things up e.g. soft cpu bandwidth and/or uclamp. Bug: 170507876 Bug: 171740453 Test: boot and check cgroup Change-Id: Iaeb081bc4f214aa23eb281e0c28a81ea581bb4d1
