OpenVG Benchmark

longyun — Thu, 05 Jul 2018 15:50:59 GMT

I run VGStressTest in imx-gpu-sdk and compare Benchmark between different backend (fb, wayland) , different Release (L4.1.15_2.0.0_ga, L3.14.52-1.1.0_ga). The issue is that the performance between different backend in same Release version is almost same, but the benchmark in Release L4.1.15_2.0.0_ga is a half of L3.14.52-1.1.0_ga. I built these images in Release L4.1.15_2.0.0_ga from Yoctor Project, and got L3.14.52-1.1.0_ga image from nxp factory SD card. My test board is imx6qpsabresd. I want to know what causes GPU performance degradation.

Hi Long

performance may be affected by arm/gpu errata fixes which were added in latest linux bsps,

for example please check #define CONFIG_ARM_ERRATA* in uboot/include/configs/mx6_common.h

uboot-imx.git - Freescale i.MX u-boot Tree

Best regards
igor
