Remove libutils.so dependency from libRSDriver, libRSCpuRef, and most
parts of libRS_internal.
NOTE: we're resolving dependencies to provide a model for vendors.
For us, all this code is above the HAL, thus the dependencies
are acceptable; whereas for vendors, their equivalent of this code is
below the HAL, and so the dependencies are not acceptable.
This CL resolves the libutils dependency by:
- Implement the timings functions in android::renderscript namespace
using NDK APIs, instead of using libutils counterparts.
- Replace android::Vector and android::String8 by std::vector and
std::string.
- PROPERTY_VALUE_MAX is replaced as PROP_VALUE_MAX.
This CL didn't resolve the libutils dependency of rsFont.cpp and
rsDebugger.cpp in libRS_internal:
The dependent functionality in rsDebugHelper.h is off by default, and
only intended for use during development; and rsFont.cpp is part of
graphics API which is not implemented below the HAL and is not used as
a model by vendors.
Additionally, this CL fixed the bug that mNodes was sorted in a
decreasing order. Nodes in ScriptGroup should be executed in
ascending order. The bad sort was only for support lib; so there was a
previously-unknown bug in support lib implementation of ScriptGroup.
Background:
libutils contains a collection of things like Vector, String8,
CallStack. It served the purpose similar to a STL library, when there
was no stable STL implementation available in Android. And most
importantly, it is not part of NDK.
Support lib used to use our own implementations of android::Vector and
android::String8, because it can only depend on NDK, similarly for the
timing related functions.
As part of the Treble requirements, native RS, including vendor version
libRS_internal, libRSDriver, libRSCpuRef could only depend on NDK
too. So we need to break the dependency on libutils. And since we now
have reasonable support of STLs, we should use that instead.
Bug: 34396220
Test: mm, and all CTS tests pass on Bullhead;
RsTest and RSTest_CompatLib (both native and compat path) also pass.
