From 930fa39c601d1601884ca6ead9f44841f0348f18 Mon Sep 17 00:00:00 2001 From: Martin Braun Date: Wed, 26 Jan 2022 10:12:38 +0100 Subject: rfnoc: Update the MTU forwarding property for some blocks Note that the default MTU forwarding policy is ONE_TO_ONE, therefore, it is only strictly necessary to modify the MTU forwarding policy for blocks that route data in a different manner. However, it may be nice to explicitly state the forwarding policy for the benefit of the reader. The following blocks had their policies updated: - addsub: ONE_TO_FAN - duc: ONE_TO_ONE - dmafifo: ONE_TO_ONE - null block: DROP - replay block: DROP - split stream: ONE_TO_FAN - switchboard: ONE_TO_FAN --- host/lib/rfnoc/split_stream_block_control.cpp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'host/lib/rfnoc/split_stream_block_control.cpp') diff --git a/host/lib/rfnoc/split_stream_block_control.cpp b/host/lib/rfnoc/split_stream_block_control.cpp index 17485882a..b98949514 100644 --- a/host/lib/rfnoc/split_stream_block_control.cpp +++ b/host/lib/rfnoc/split_stream_block_control.cpp @@ -41,6 +41,10 @@ public: // the split stream block. set_prop_forwarding_policy(forwarding_policy_t::USE_MAP); set_action_forwarding_policy(forwarding_policy_t::USE_MAP); + // MTU forwarding doesn't allow for USE_MAP, but we assume that packets + // coming in may potentially go to any output port.
