"ARM Advanced SIMD" is an extension that provides + * instructions to perform parallel computations on vectors of 8, 16, + * 32, 64 and 128 bit quantities. NEON requires VFPv32-D32 since all + * NEON registers are also mapped to the same register banks. + * + * VFPv4-D16, adds a few instructions on top of VFPv3-D16 in order to + * perform fused multiply-accumulate on VFP registers, as well as + * half-precision (16-bit) conversion operations. + * + * VFPv4-D32 is VFPv4-D16 with 32, instead of 16, FPU double precision + * registers. + * + * VPFv4-NEON is VFPv4-D32 with NEON instructions. It also adds fused + * multiply-accumulate instructions that work on the NEON registers. + * + * NOTE: Similarly, "VFPv4" might either reference VFPv4-D16 or VFPv4-D32 + * depending on context. + * + * The following information was determined by scanning the binutils-2.22 + * sources: + * + * Basic VFP instruction subsets: + * + * #define FPU_VFP_EXT_V1xD 0x08000000 // Base VFP instruction set. + * #define FPU_VFP_EXT_V1 0x04000000 // Double-precision insns. + * #define FPU_VFP_EXT_V2 0x02000000 // ARM10E VFPr1. + * #define FPU_VFP_EXT_V3xD 0x01000000 // VFPv3 single-precision. + * #define FPU_VFP_EXT_V3 0x00800000 // VFPv3 double-precision. + * #define FPU_NEON_EXT_V1 0x00400000 // Neon (SIMD) insns. + * #define FPU_VFP_EXT_D32 0x00200000 // Registers D16-D31. + * #define FPU_VFP_EXT_FP16 0x00100000 // Half-precision extensions. + * #define FPU_NEON_EXT_FMA 0x00080000 // Neon fused multiply-add + * #define FPU_VFP_EXT_FMA 0x00040000 // VFP fused multiply-add + * + * FPU types (excluding NEON) + * + * FPU_VFP_V1xD (EXT_V1xD) + * | + * +--------------------------+ + * | | + * FPU_VFP_V1 (+EXT_V1) FPU_VFP_V3xD (+EXT_V2+EXT_V3xD) + * | | + * | | + * FPU_VFP_V2 (+EXT_V2) FPU_VFP_V4_SP_D16 (+EXT_FP16+EXT_FMA) + * | + * FPU_VFP_V3D16 (+EXT_Vx3D+EXT_V3) + * | + * +--------------------------+ + * | | + * FPU_VFP_V3 (+EXT_D32) FPU_VFP_V4D16 (+EXT_FP16+EXT_FMA) + * | | + * | FPU_VFP_V4 (+EXT_D32) + * | + * FPU_VFP_HARD (+EXT_FMA+NEON_EXT_FMA) + * + * VFP architectures: + * + * ARCH_VFP_V1xD (EXT_V1xD) + * | + * +------------------+ + * | | + * | ARCH_VFP_V3xD (+EXT_V2+EXT_V3xD) + * | | + * | ARCH_VFP_V3xD_FP16 (+EXT_FP16) + * | | + * | ARCH_VFP_V4_SP_D16 (+EXT_FMA) + * | + * ARCH_VFP_V1 (+EXT_V1) + * | + * ARCH_VFP_V2 (+EXT_V2) + * | + * ARCH_VFP_V3D16 (+EXT_V3xD+EXT_V3) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V3D16_FP16 (+EXT_FP16) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V4_D16 (+EXT_FP16+EXT_FMA) + * | | + * | ARCH_VFP_V4 (+EXT_D32) + * | | + * | ARCH_NEON_VFP_V4 (+EXT_NEON+EXT_NEON_FMA) + * | + * ARCH_VFP_V3 (+EXT_D32) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V3_FP16 (+EXT_FP16) + * | + * ARCH_VFP_V3_PLUS_NEON_V1 (+EXT_NEON) + * | + * ARCH_NEON_FP16 (+EXT_FP16) + * + * -fpu=<name> values and their correspondance with FPU architectures above: + * + * {"vfp", FPU_ARCH_VFP_V2}, + * {"vfp9", FPU_ARCH_VFP_V2}, + * {"vfp3", FPU_ARCH_VFP_V3}, // For backwards compatbility. + * {"vfp10", FPU_ARCH_VFP_V2}, + * {"vfp10-r0", FPU_ARCH_VFP_V1}, + * {"vfpxd", FPU_ARCH_VFP_V1xD}, + * {"vfpv2", FPU_ARCH_VFP_V2}, + * {"vfpv3", FPU_ARCH_VFP_V3}, + * {"vfpv3-fp16", FPU_ARCH_VFP_V3_FP16}, + * {"vfpv3-d16", FPU_ARCH_VFP_V3D16}, + * {"vfpv3-d16-fp16", FPU_ARCH_VFP_V3D16_FP16}, + * {"vfpv3xd", FPU_ARCH_VFP_V3xD}, + * {"vfpv3xd-fp16", FPU_ARCH_VFP_V3xD_FP16}, + * {"neon", FPU_ARCH_VFP_V3_PLUS_NEON_V1}, + * {"neon-fp16", FPU_ARCH_NEON_FP16}, + * {"vfpv4", FPU_ARCH_VFP_V4}, + * {"vfpv4-d16", FPU_ARCH_VFP_V4D16}, + * {"fpv4-sp-d16", FPU_ARCH_VFP_V4_SP_D16}, + * {"neon-vfpv4", FPU_ARCH_NEON_VFP_V4}, + * + * + * Simplified diagram that only includes FPUs supported by Android: + * Only ARCH_VFP_V3D16 is actually mandated by the armeabi-v7a ABI, + * all others are optional and must be probed at runtime. + * + * ARCH_VFP_V3D16 (EXT_V1xD+EXT_V1+EXT_V2+EXT_V3xD+EXT_V3) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V3D16_FP16 (+EXT_FP16) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V4_D16 (+EXT_FP16+EXT_FMA) + * | | + * | ARCH_VFP_V4 (+EXT_D32) + * | | + * | ARCH_NEON_VFP_V4 (+EXT_NEON+EXT_NEON_FMA) + * | + * ARCH_VFP_V3 (+EXT_D32) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V3_FP16 (+EXT_FP16) + * | + * ARCH_VFP_V3_PLUS_NEON_V1 (+EXT_NEON) + * | + * ARCH_NEON_FP16 (+EXT_FP16) + * + */ diff --git a/winpr/libwinpr/sysinfo/cpufeatures/cpu-features.h b/winpr/libwinpr/sysinfo/cpufeatures/cpu-features.h new file mode 100644 index 0000000..9520c8a --- /dev/null +++ b/winpr/libwinpr/sysinfo/cpufeatures/cpu-features.h @@ -0,0 +1,324 @@ +/* + * Copyright (C) 2010 The Android Open Source Project + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in + * the documentation and/or other materials provided with the + * distribution. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS + * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT + * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS + * FOR A PARTICULAR PURPOSE ARE DISCLAIMED.
