10adb0c2029f112b5738228617d5645f6ecea0c5 29-Mar-2016 David Gross <dgross@google.com> Multithreaded execution of certain general reduction kernels; reduction test overhaul.

A reduction kernel is eligible for multithreaded execution if it has a
combiner function and it is launched over a 1D iteration space.

Note: Properties debug.rs.reduce-accum and debug.rs.reduce-split-accum
are added for debugging multithreaded reduction.

The following changes are made to reduction tests in RsTest:
- Overhaul the test framework -- now data-driven, and can execute the same
test multiple times with different seeds and input sizes, features
separate sets of quick correctness tests, full correctness tests,
and performance tests. (Performance tests are not run by default.)
- Report timing information for test execution.
- Report more information for fz* kernel testing.
- Remove dp kernel testing -- this involved floating-point arithmetic
which is not guaranteed to produce identical results between java
and rs or for different rs multithreaded executions.
- Add sumgcd kernel testing. This is intended to be representative of
a compute-heavy kernel.
- findMinAndMax kernel testing must compare cell value not cell index
-- two or more cells might have the same min or max value, and java
and various rs multithreaded executions are not guaranteed to find
the same cell.
- Fix bug in findMinAndMax kernel's combiner function. (It behaved
incorrectly when operating on an accumulator datum that has been
initialized but never passed to the accumulator function.)
- RsTest now requests largeHeap.

Requires coordinated change in frameworks/compile/libbcc in order
for RsTest to run.

At present, general reduction kernels are run single-threaded.

Also: Remove dead struct field MTLaunchStructForEach::sig.

11fd9ec1ab8dfa7ae45c6edeea48dddc4633efea 11-Jul-2015 Matt Wala <wala@google.com> CPU ref: Fix potential buffer over-read / uninitialized memory access.

GetCpuInfo() was reading /proc/cpuinfo into a string without properly
null terminating the result. The resulting unterminated string was
being passed to strstr().

Change the code to read the file with fgets(), which ensures the
result is null terminated. Also, document the GetCpuInfo() function
and the global variable that it sets.

8409d6414dd4a42aa59779fcfe9fce18648cb135 29-Apr-2015 Stephen Hines <srhines@google.com> Add RSGlobalInfoPass information to RS driver.

Bug: 20306487

This change enables vendor drivers to configure support for including
additional information about global variables in the emitted CPU code.
This information includes the number of total global variables, the
names of these variables, the addresses of these variables and the
sizes of these variables. The driver can also select whether the
information includes constant (immutable) globals or not.

The reference driver defaults to embedding information about each of
the existing, non-constant global variables.

Bug: 18322681

- In rsCpuScript, if property rs.skip.linkloader is set, look for a .so
file in the cache directory and load it. If it is not available, use
bcc to generate relocatable object file and link it to a .so using
ld.mc. Use the embedded symbols in .rs.info and follow steps similar
to the compatibility library to invoke script functions or access
script variables.
- Add rs* symbols like rsGetAllocation to libRSCpuRef (ala
libRSSupport). Do necessary changes to argument types to get mangled
names correct.
- Make 64-bit version of rsSetObject take two pointers instead of a
pointer and a large object. rsIsObject takes a pointer instead of a
large object. Otherwise, we get failures in x86_64 due to calling
convention mismatch. To match the function names in the shared object
path, define these functions as 'extern "C"' with their mangled names.
- Add stubbed Math functions from rsCpuRuntimeMath and
rsCpuRuntimeMathFuncs into libRSCpuRef.so.
- Coalesce separate #ifdef paths in libRSCpuRef. Function parameters
for runtime callbacks and bcc plugin are needed in the
non-compatibilty path, but take default NULL arguments. This patch
introduces these parameters into the compatibility path as well, and
passes default NULL arguments.

This patch simplifies the RenderScript driver and CPU reference implementation
by removing the distinction between sing- and multi-input kernels in many
places. The distinction is maintained in some places due to the need to
maintain backwards compatibility. This permits the deletion of some functions
and struct members that are no longer needed. Several related functions were
also cleaned up.

This patch splits the RsForEachStubParamStruct into two smaller structs, one
used specifically by the driver and the other by the expanded kernels. Doing
so makes it clearer what data is used where. In addition, fewer data are
copied between memory locations during kernel invocation.

Several fields that were not being used were removed from the structs.

4b3c34e6833e39bc89c2128002806b654b8e623d 11-Jun-2014 Chris Wailes <chriswailes@google.com> Adds support for multi-input kernels to Frameworks/RS.

This patch modifies Frameworks/RS in the following ways:
* Adjusted the data-layout of the C/C++ version of RsForEachStubParamStruct to
accommodate a pointer to an array of input allocations and a pointer to an
array of stride sizes for each of these allocatoins.
* Adds a new code path for Java code to pass multiple allocations to a RS
* Packs base pointers and step values for multi-input kernels into the new
RsForEachStubParamStruct members.

Bug: 7342767

This change adds support (hidden behind the EXTERNAL_BCC_COMPILER ifdef)
for loading plugin libraries via the external bcc toolchain. The external
bcc compiler loads the named library and will then invoke a customized
rsCompilerDriverInit() from that library.
