From fe3fa1dd31b6da9c90cf181d64d6829313804cdd Mon Sep 17 00:00:00 2001 From: Sugandha Gupta Date: Fri, 25 Jan 2019 17:36:26 -0800 Subject: device3: Constraint send/recv_frame_size based on down/upstream MTU We need to properly contraint the send/recv_frame_size based on the minimum MTU of all the down/upstream blocks. This fixes the issue with E310 tx/rx streaming as it has smaller MTU sizes than the other usrps. --- host/lib/rfnoc/sink_block_ctrl_base.cpp | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) (limited to 'host/lib/rfnoc/sink_block_ctrl_base.cpp') diff --git a/host/lib/rfnoc/sink_block_ctrl_base.cpp b/host/lib/rfnoc/sink_block_ctrl_base.cpp index bb81706f9..f1d65350a 100644 --- a/host/lib/rfnoc/sink_block_ctrl_base.cpp +++ b/host/lib/rfnoc/sink_block_ctrl_base.cpp @@ -43,11 +43,19 @@ std::vector sink_block_ctrl_base::get_input_ports() const **********************************************************************/ size_t sink_block_ctrl_base::get_fifo_size(size_t block_port) const { - if (_tree->exists( - _root_path / "input_buffer_size" / str(boost::format("%d") % block_port))) { + if (_tree->exists(_root_path / "input_buffer_size" / std::to_string(block_port))) { return _tree ->access( - _root_path / "input_buffer_size" / str(boost::format("%d") % block_port)) + _root_path / "input_buffer_size" / std::to_string(block_port)) + .get(); + } + return 0; +} + +size_t sink_block_ctrl_base::get_mtu(size_t block_port) const +{ + if (_tree->exists(_root_path / "mtu" / std::to_string(block_port))) { + return _tree->access(_root_path / "mtu" / std::to_string(block_port)) .get(); } return 0; -- cgit v1.2.3
