From: Emma Finn <[email protected]> This commit adds a new command to allow the user to switch the active action implementation at runtime.
Usage: $ ovs-appctl odp-execute/action-impl-set scalar This commit also adds a new command to retrieve the list of available action implementations. This can be used by to check what implementations of actions are available and what implementation is active during runtime. Usage: $ ovs-appctl odp-execute/action-impl-show Added separate test-case for ovs-actions show/set commands: PMD - ovs-actions configuration Signed-off-by: Emma Finn <[email protected]> Signed-off-by: Kumar Amber <[email protected]> Signed-off-by: Sunil Pai G <[email protected]> Co-authored-by: Kumar Amber <[email protected]> Co-authored-by: Sunil Pai G <[email protected]> Acked-by: Harry van Haaren <[email protected]> --- v9: rebase conflict on NEWS --- NEWS | 2 ++ lib/automake.mk | 1 + lib/odp-execute-private.c | 12 ++++++++++ lib/odp-execute-private.h | 2 ++ lib/odp-execute-unixctl.man | 10 +++++++++ lib/odp-execute.c | 44 +++++++++++++++++++++++++++++++++++++ tests/pmd.at | 39 ++++++++++++++++++++++++++++++++ vswitchd/ovs-vswitchd.8.in | 1 + 8 files changed, 111 insertions(+) create mode 100644 lib/odp-execute-unixctl.man diff --git a/NEWS b/NEWS index aeba359e5..cf35f4ae4 100644 --- a/NEWS +++ b/NEWS @@ -51,6 +51,8 @@ Post-v2.17.0 The old variant is kept for backward compatibility. * Add actions auto-validator function to compare different actions implementations against default implementation. + * Add command line option to switch between different actions + implementations available at run time. - Linux datapath: * Add offloading meter tc police. diff --git a/lib/automake.mk b/lib/automake.mk index 23ba4fab0..5c3b05f6b 100644 --- a/lib/automake.mk +++ b/lib/automake.mk @@ -584,6 +584,7 @@ MAN_FRAGMENTS += \ lib/netdev-dpdk-unixctl.man \ lib/dpif-netdev-unixctl.man \ lib/dpif-netlink-unixctl.man \ + lib/odp-execute-unixctl.man \ lib/ofp-version.man \ lib/ovs.tmac \ lib/ovs-replay.man \ diff --git a/lib/odp-execute-private.c b/lib/odp-execute-private.c index 780d6d289..38be22ec9 100644 --- a/lib/odp-execute-private.c +++ b/lib/odp-execute-private.c @@ -67,6 +67,18 @@ odp_execute_action_set(const char *name) return NULL; } +void +odp_execute_action_get_info(struct ds *string) +{ + ds_put_cstr(string, "Available Actions implementations:\n"); + for (int i = 0; i < ACTION_IMPL_MAX; i++) { + ds_put_format(string, " %s (available: %s, active: %s)\n", + action_impls[i].name, + action_impls[i].available ?
