3.3 Configure IPU to Support IPUMM and Decode Link at the Same Time

Linux use the IPUMM to decode in PSDKLA. The decode/encode link is in VISION-SDK for RVC/Animation decoding. So, you must support IPUMM and the decode link in M4. This should be configured in cfg.mk

For example, in J6 EVM: sdk/vision_sdk/apps/configs/tda2xx_evm_linux_all/cfg.mk IVAHD_INCLUDE aims to support the decode/encode link. IPUMM_INCLUDE aims to support IPUMM. The reference code is shown below:

# Both IVAHD_INCLUDE & IPUMM_INCLUDE should not be set to "yes"
# Only one should be enabled to avoid IVA-HD resource conflict
IPUMM_INCLUDE=yes
IVAHD_INCLUDE=yes
