From f516b51169020ea1957010fbd1005d746f01b1d9 Mon Sep 17 00:00:00 2001 From: dimitri staessens Date: Wed, 19 Oct 2016 22:25:46 +0200 Subject: lib: Demultiplex the fast path The fast path will now use an incoming ring buffer per flow per process. This necessitated the development of a new method for the asynchronous io call, which is now based on an event queue system for scalability (fqueue). The ipcpd's and tools have been updated to this API. --- include/ouroboros/shm_flow_set.h | 63 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 include/ouroboros/shm_flow_set.h (limited to 'include/ouroboros/shm_flow_set.h') diff --git a/include/ouroboros/shm_flow_set.h b/include/ouroboros/shm_flow_set.h new file mode 100644 index 00000000..32db5d36 --- /dev/null +++ b/include/ouroboros/shm_flow_set.h @@ -0,0 +1,63 @@ +/* + * Ouroboros - Copyright (C) 2016 + * + * Management of flow_sets for fqueue + * + * Dimitri Staessens + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
