ENGR00163697 - FEC : Adjust MX53 Network stream throughput.
- When the system is very busy(such as play 1080p streaming in local)
the WIFI & FEC performance were very low.
- Enable the patch in uboot for WIFI and FEC performance:
If WIFI connect to PORT2, enable the config:
CONFIG_ADJUST_WIFI_FEC_PERFORMANCE
CONFIG_WIFI_SDHC_PORT2
If WIFI connect to port3, enable the config:
CONFIG_ADJUST_WIFI_FEC_PERFORMANCE
CONFIG_WIFI_SDHC_PORT3
- The solution of the patch:
I. Changing M4IF dynamic jump value to zero, which can guarantee FEC the
high rate of accessing bus.
II. Increase Master 4 priority for FEC.
Increase Master 2 and AHBMAX priority for WIFI.
- Test result:
i.MX53 FEC bandwidth (1080p streaming playback in local): 47.1 Mbits/sec.
