what mean is notifyk.vpssm3_sva ?

Hi,

Mem is for declaring the total memory available to Linux. " notifyk.vpssm3_sva" is the address shared between Media controller and A8 Linux for doing Notify calls. Notify is used by VPSS.ko and V4L2 drivers. Here is link for memory map understanding for EZSDK http://processors.wiki.ti.com/index.php/EZSDK_Memory_Map

Hi,

As you are using DVRRDK, please refer to the memory map in <DVR_RDK_BASE>/dvr_rdk/mcfw/src_bios6/cfg/ti816x/config_1G.bld

This would tell you the size of each section and how the address of each section is calculated. We will have more detailed documentation about memory map in DVRRDK GA planned for Feb end.

For exact details on why the particular notify section is needed, you can refer to http://processors.wiki.ti.com/index.php/DM816X_AM389X_VPSS_Video_Driver_User_Guide
