Since aarch64 has different neon syntax from aarch32 and has no support of (older) arm-simd, there are no SIMD accelerations for pixman on aarch64.
We need new implementations. Added: https://bugs.freedesktop.org/show_bug.cgi?id=94758 The patch is too large (yes, 10k lines of asm are added), I cannot attach the patch to this mail. Please find proposed patch from the above bug ticket, or just check: https://bugs.freedesktop.org/attachment.cgi?id=122634 Benchmark results are attached above ticket. Typical result is: normal: src_n_8_x888 = L1: 38.33 L2: 40.58 M: 39.91 ( 11.87%) HT: 31.31 VT: 30.42 R: 29.14 RT: 18.14 ( 171Kops/s) src_n_8_8888 = L1: 38.37 L2: 40.61 M: 39.92 ( 11.87%) HT: 31.30 VT: 30.41 R: 29.14 RT: 18.11 ( 171Kops/s) neon: src_n_8_x888 = L1: 344.76 L2: 348.59 M:275.93 ( 80.42%) HT:116.32 VT:109.72 R: 92.61 RT: 40.25 ( 348Kops/s) src_n_8_8888 = L1: 346.17 L2: 348.63 M:276.15 ( 80.48%) HT:116.43 VT:109.72 R: 92.48 RT: 40.28 ( 348Kops/s) I've only tested the code with Qualcomm DragonBoard 410c (Cortex-A53 * 4, 1.2GHz). Can anyone test it on other aarch64 platform ?
