iMX6Q VPU performance

What settings would give lower memory load?

Anyway I think someone at Freescale should be able to answer if it is possible to encode 1920x1080 @ 30 fps with memory running at 396 MHz or if it is some other issue we are facing.

Hello,

You may try the following :

Make sure below QoS settings are done in u-boot DCD table:

/* enable AXI cache for VDOA/VPU/IPU */

DATA 4 0x020e0010 0xF00000CF

/* set IPU AXI-id0 Qos=0xf(bypass) AXI-id1 Qos=0x7 */

DATA 4 0x020e0018 0x007F007F

DATA 4 0x020e001c 0x007F007F

2.
Force CPU to run at maximal frequency

$ echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Have a great day,
Yuri
