Merge pull request #1829 from ashwinyes/develop_aarch64_dynamic_arch_support 
Add DYNAMIC_ARCH support for ARM64

Ashwin Sekhar T K d5aeff636f ARM64: Enable DYNAMIC_ARCH 
Enable DYNAMIC_ARCH feature on ARM64. This patch uses the cpuid
feature in linux kernel to detect the core type at runtime
(https://www.kernel.org/doc/Documentation/arm64/cpu-feature-registers.txt).

If this feature is missing in kernel, then the user should use the
OPENBLAS_CORETYPE env variable to select the desired core type.

Ashwin Sekhar T K d50abc8903 ARM64: Move parameters from parameter.c to param.h 
Remove the runtime setting of P, Q, R parameters for
targets ARMV8, THUNDERX2T99. Instead set them as constants
in param.h at compile time.

Ashwin Sekhar T K 351a0c777c ARM64: Remove XGENE1 references 
Remove XGENE1 target as the implementation for the
same is incomplete. Moreover whoever wishes to use
on XGENE1 can use the generic ARMV8 target as there
are no XGENE1 specific optimizations in OpenBLAS.

Merge pull request #1821 from ashwinyes/develop_aarch64_armv8neonkernels 
Use ThunderX2 Neon Kernels for ARMV8 Target
 2018-10-18 08:13:05 +02:00
Ashwin Sekhar T K 21f46a1cf2 ARM64: Use THUNDERX2T99 Neon Kernels for ARMV8 
Currently the generic ARMV8 target uses C implementations
for many routines. Replace these with the neon implementations
written for THUNDERX2T99 target which are upto 6x faster for
certain routines.
