This flag adds "apps" and "system" cgroups underneath the v2 hierarchy
root. Cgroups with UIDs < 10000 (AID_APP_START) will be placed
under "system" and others will be placed under "apps". UIDs under 10000
are reserved for core Android subsystems. This allows us to
apply different cgroup controls collectively to system processes and
normal applications.

This flag prevents memcg from being mounted as a v1 hierarchy, even if
cgroups.json specifies it should be mounted as v1. It will activate
memcg in the v2 hierarchy even if cgroups.json does not specify that it
should be activated in the v2 hierarchy.
The cgroup_disable=memory kernel command line argument will still
prevent memcg from being activated, as this forced memcg controller
is marked as optional.

We already get -Wall and -Werror from the build system, and we do not
want/need -Wexit-time-destructors since it prevents local statics with
non-trivial destructors.

This change enables headers like <span>. Inside the <span> header file
file the following guard makes its functionality unavailable when
building with std=gnu++-17:
#if _LIBCPP_STD_VER > 17
[ ... ]
#endif

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".

vendor_available modules were available to product modules.
However, not all vendor_available modules are required to be
available to product modules. Some modules want to be available only
to product modules but not vendor modules.
To cover the requirement, we separate product_available from
vendor_available.
vendor_available will not provide product available module.
Rename libcutils/include_vndk to libcutils/include_outside_system as
it provides the headers to the modules outside the system partition
including /product.

Modules contributing mainline modules (APK/APEX) should set
min_sdk_version as well as apex_available.
For now setting min_sdk_version doesn't change build outputs.
But build-time checks will be added soon.

whitelist by adding apex_available property to the Android.bp of the

Android build system added support for building translated binaries
used on natively bridged targets (arm on x86 for example).
However in order to avoid building unnecessary binaries and libraries
for such architectures most modules do not support native bridge by default.
All needed modules have to explicitly indicate if they may be used as part
of translated binary build.
This change enabled native bridge support for libprocessgroup modules
needed by libutils greylisted library (available for apps targeting
Android version < N).

The majority of libjsoncpp use is due to libprocessgroup. Static
linking reduces relocations required at runtime as well as compacts the
pages dirtied by relocations. On a 32-bit system, where this matters
the most, this reduces 8KB of dirty pages per libprocessgroup load.
Overall, the dirty page reduction on 32-bit cuttlefish is ~500KB.
Bug: 132275636
Test: Boot on cuttlefish. Calculate total amount of dirty memory used
for libprocessgroup and libjsoncpp.

(cherry picked from commit b562e68503)
Use the LL-NDK library to read cgroup.rc.
As a side-effect, the CgroupController class is changed
to a wrapper of ACgroupController* from the library. The
class itself essentially becomes the pointer, and can be
trivially copied. Modify all client code for this change.

Abstract usage of cgroups into task profiles that allows for changes
in cgroup hierarchy and version without affecting framework codebase.
Rework current processgroup and sched_policy API function implementations
to use task profiles instead of hardcoded paths and attributes.
Mount cgroups using information from cgroups.json rather than from init.rc
