Subject: [dpdk-dev] [PATCH v8 0/4] ethdev: add speed capabilities and refactor link API
Date: Sun, 14 Feb 2016 23:17:35 +0100	[thread overview]
Message-ID: <1455488259-1000-1-git-send-email-marcdevel@gmail.com> (raw)
In-Reply-To: <1454028127-10401-1-git-send-email-marcdevel@gmail.com>

The current rte_eth_dev_info abstraction does not provide any mechanism to
get the supported speed(s) of an ethdev.

For some drivers (e.g. ixgbe), an educated guess could be done based on the
driver's name (driver_name in rte_eth_dev_info), see:

http://dpdk.org/ml/archives/dev/2013-August/000412.html

However, i) doing string comparisons is annoying, and can silently
break existing applications if PMDs change their names ii) it does not
provide all the supported capabilities of the ethdev iii) for some drivers it
is impossible determine correctly the (max) speed by the application
(e.g. in i40, distinguish between XL710 and X710).

In addition, the link APIs do not allow to define a set of advertised link
speeds for autonegociation.

This series of patches adds the following capabilities:

* speed_capa bitmap in rte_eth_dev_info, which is filled by the PMDs
  according to the physical device capabilities.
* refactors link API in ethdev to allow the definition of the advertised
  link speeds, fix speed (no auto-negociation) or advertise all supported
  speeds (default).

WARNING: this patch series, specifically 3/4, is NOT tested for most of the
PMDs, due to the lack of hardware. Only generic EM is tested (VM). Reviewing
and testing required by PMD maintainers.

* * * * *

v2: rebase, converted speed_capa into 32 bits bitmap, fixed alignment
(checkpatch).

v3: rebase to v2.1. unified ETH_LINK_SPEED and ETH_SPEED_CAP into ETH_SPEED.
    Converted field speed in struct rte_eth_conf to speed, to allow a bitmap
    for defining the announced speeds, as suggested M. Brorup. Fixed spelling
    issues.

v4: fixed errata in the documentation of field speeds of rte_eth_conf, and
    commit 1/2 message. rebased to v2.1.0. v3 was incorrectly based on
    ~2.1.0-rc1.

v5: revert to v2 speed capabilities patch. Fixed MLX4 speed capabilities
    (thanks N. Laranjeiro). Refactored link speed API to allow setting
    advertised speeds (3/4). Added NO_AUTONEG option to explicitely disable
    auto-negociation. Updated 2.2 rel. notes (4/4). Rebased to current HEAD.

v6: Move link_duplex to be part of bitfield. Fixed i40 autoneg flag link
    update code. Added rte_eth_speed_to_bm_flag() to .map file. Fixed other
    spelling issues. Rebased to current HEAD.

v7: Rebased to current HEAD. Moved documentation to v2.3. Still needs testing
    from PMD maintainers.

v8: Rebased to current HEAD. Modified em driver impl. to not touch base files.
    Merged patch 5 into 3 (map file). Changed numeric speed to a 64 bit value.
    Filled-in speed capabilities for drivers bnx2x, cxgbe, mlx5 and nfp in
    addition to the ones of previous patch sets.
