Subject: [dpdk-dev] [PATCH 0/2] Eventdev ABI changes for DLB/DLB2
Date: Wed, 14 Oct 2020 16:36:13 -0500 [thread overview]
Message-ID: <1602711375-10685-1-git-send-email-timothy.mcdaniel@intel.com> (raw)
In-Reply-To: <1599843507-19970-2-git-send-email-timothy.mcdaniel@intel.com>
This series implements the eventdev ABI changes required by
the DLB and DLB2 PMDs. This ABI change was announced in the
20.08 release notes [1]. This patch was initially part of
the V1 DLB PMD patchset.
The DLB hardware does not conform exactly to the eventdev interface.
1) It has a limit on the number of queues that may be linked to a port.
2) Some ports are further restricted to a maximum of 1 linked queue.
3) It does not (currently) have the ability to carry the flow_id as part
of the event (QE) payload.
Due to the above, we would like to propose the following enhancements.
1) Add new fields to the rte_event_dev_info struct. These fields allow
the device to advertise its capabilities so that applications can take
the appropriate actions based on those capabilities.
2) Add a new field to the rte_event_dev_config struct. This field allows
the application to specify how many of its ports are limited to a single
link, or will be used in single link mode.
3) Replace the dedicated implicit_release_disabled field with a bit field
of explicit port capabilities. The implicit_release_disable functionality
is assigned to one bit, and a port-is-single-link-only attribute is
assigned to another, with the remaining bits available for future
assignment.
Note that it was requested that we split this app/test
changes out from the eventdev ABI patch. As a result,
neither of these patches will build without the other
also being applied.
Major changes since V1:
Reworded commit message, as requested
Fixed errors reported by clang
Testing showed no performance impact due to the flow_id template code
added to test app.
