send bits buffer via IPC Links

Marat Shchuchinsky

Hello TI Teams!

Please let me know - Is this problem in MCFW (DVR-RDK for DM8168) sends data from DSP-ALG via IPC links direct to Host(A8), as is following connection:

[SYSTEM_LINK_ID_ALG_0] => [SYSTEM_DSP_LINK_ID_IPC_BITS_OUT_1] => [SYSTEM_HOST_LINK_ID_IPC_BITS_IN_1] => listen task

ThanX alot

This should work.

Is SYSTEM_DSP_LINK_ID_IPC_BITS_OUT_0 / SYSTEM_HOST_LINK_ID_IPC_BITS_IN_0 getting used for some other transfer?

ThanX for reply. but SYSTEM_HOST_LINK_ID_IPC_BITS_IN_0 used for recieve video encoded data. What about use

SYSTEM_DSP_LINK_ID_IPC_BITS_OUT_0 => SYSTEM_HOST_LINK_ID_IPC_BITS_IN_1 ??

Yes, it can be used.

ThanX again.

This IPC require any buffer' address translation on A8 side (Linux)? or address translation performed automatically by IPC links. I mean adress translation from DSP physical address to Linux virtual address.
