am: 248e44fd4d am: 2d7db226f8 am: 70af4c884f Change-Id: I1ba365aa50baa7bb39a7875b6ce584aabd43b78a
2016-11-17Fix google-build-using-namespace warnings in cpu_ref.Chih-Hung Hsieh
* Remove "using namespace ..." statements. * Replace them with using declarations of the required names. * Enclose the C++ methods and static and extern "C" functions with namespace android and renderscript. * Keep global C++ functions as-is and add using declarations for them. Bug: 32670901 Test: build with WITH_TIDY=1 Change-Id: I818de466e8786a6c4f9ce0cd8e0fe027f34d7fad
2016-07-11Make boundary-check stricter.Hidehiko Abe
There was a bug to access uninitialized buffer. This CL fixes it. BUG=b/29375932 Change-Id: I16b57d8f06f493c6996c6aeacdaf139833e62653
2016-04-21Refactor ARM Blur prefill logic.Simon Hosie
Refactor the prefill logic for ARM (and improve documentation along the way) so as to fix some cases where data is read outside of the source image, and to minimise the remaining cases which must fall back to the C implementation. Change-Id: I3d06416b40c48dea06258e9f7bb5ddc246d7c710
2015-05-22Use "override" instead of "virtual" when replacing methods.Stephen Hines

2015-03-16Pass RsExpandKernelDriverInfo not RsExpandKernelParams.David Gross
Which is to say: retire RsExpandKernelParams and pass RsExpandKernelDriverInfo directly to kernel wrapper functions instead. Requires related change in frameworks/compile/libbcc. Change-Id: I453f45ec18f389e88e27fcfa57ddf245d077cb98
2014-11-10Enable ASM path for blur intrinsic when clippedJason Sams

2014-08-22Fix x86 build for SSSE3.Dan Albert
These functions were previously defined in a C file. The file was renamed to C++, but the extern "C"s were not removed. Change-Id: I62ec9ba7c73d24c221bbe3f7580cfd7f09bf701c

2014-08-18Remove the instep parameter.Chris Wailes
This patch removes the instep parameter from calls to expanded kernels and from the CPU reference implementation intrinsics. Change-Id: I059db548a57702c576963f6b17a002b2ee393cdb
2014-07-15Split the RsForEachStubParamStruct in two.Chris Wailes
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.

2014-05-22Enable ARM64 intrinsics.Jason Sams
This also moves ARM intrinsic ifdefs behing ARCH_ARM_USE_INTRINSICS instead of ARCH_ARM_HAVE_VFP. Change-Id: I48d3d55c77feb931e22288828247e281db43d32b

2014-04-22Improve RS intrinsics performance.Rose, James
Renderscript CPU performance for intrinsics cases is not good for x86 platforms. In many cases it is significantly slower even with SIMD Intrinsics. In current x86 implementation it is using full 32 bit multiplies which aren't well supported on current Atom platforms. This patch uses 16 bit multiply with 32 bit add pmaddwd instruction where appropriate. It also adds atom specificoptimizations to improve RS intrinsics performance.

2013-01-14Align all allocations to a 16-byte boundary.Stephen Hines
This change also fixes an issue in the Blur intrinsic, where we mis-cast a float array to float4 (and thus encountered some new alignment errors with the updated LLVM). Change-Id: I3955b38f156c35f4d160652c75ab416bae09b2c8
