[dpdk-dev] [PATCH v5 0/9] Expose IXGBE extended stats to DPDK apps

[dpdk-dev] [PATCH v5 0/9] Expose IXGBE extended stats to DPDK apps

[Maryam Tahhan]

This patch set implements xstats_get() and xstats_reset() in dev_ops for
ixgbe to expose detailed error statistics to DPDK applications. The
dump_cfg application was extended to demonstrate the usage of
retrieving statistics for DPDK interfaces and renamed to proc_info
in order reflect this new functionality. This patch set also removes non
generic statistics from the statistics strings at the ethdev level and
marks the relevant registers as depricated in struct rte_eth_stats.

v2:
 - Fixed patch dependencies.
 - Broke down patches into smaller logical changes.

v3:
 - Removes non-generic stats fields in rte_stats_strings and deprecates
   the fields related to them in struct rte_eth_stats.
 - Modifies rte_eth_xstats_get() to return generic stats and extended stats.
 
v4:
 - Replace count use in the loop in ixgbe_dev_xstats_get() function definition with i.
 - Breakdown "ixgbe: add NIC specific stats removed from ethdev" into two patches, one
   that adds the stats and another that extends ierrors to include more error stats.
 - Remove second call to ixgbe_dev_xstats_get() from rte_eth_xstats_get().

v5:
 - Added documentation for proc_info.
 - Fixed proc_info copyright year.
 - Display queue stats for all devices in proc_info.

Maryam Tahhan (9):
  ixgbe: move stats register reads to a new function
  ixgbe: add functions to get and reset xstats
  ethdev: expose extended error stats
  ethdev: remove HW specific stats in stats structs
  ixgbe: add NIC specific stats removed from ethdev
  ixgbe: return more errors in ierrors
  app: remove dump_cfg
  app: add a new app proc_info
  doc: Add documentation for proc_info

[dpdk-dev] [PATCH v5 1/9] ixgbe: move stats register reads to a new function

[Maryam Tahhan]

Move stats register reads to ixgbe_read_stats_registers() as it will be
used by the functions to retrieve stats and extended stats.

+proc_info Application
+========================
+
+The proc_info application is a Data Plane Development Kit (DPDK) application
+that runs as a DPDK secondary process and is capable of retrieving port
+statistics, resetting port statistics and printing DPDK memory information.
+This application extends the original functionality that was supported by
+dump_cfg.
+
+Running the Application
+-----------------------
+The application has a number of command line options:
+
+.. code-block:: console
+
+   ./$(RTE_TARGET)/app/proc_info -- -m | [-p PORTMASK] [--stats | --xstats |
+   --stats-reset | --xstats-reset]
+
+Parameters
+~~~~~~~~~~
+**-p PORTMASK**: Hexadecimal bitmask of ports to configure.
+
+**--stats**
+The stats parameter controls the printing of generic port statistics. If no
+port mask is specified stats are printed for all DPDK ports.
+
+**--xstats**
+The stats parameter controls the printing of extended port statistics. If no
+port mask is specified xstats are printed for all DPDK ports.
+
+**--stats-reset**
+The stats-reset parameter controls the resetting of generic port statistics. If
+no port mask is specified, the generic stats are reset for all DPDK ports.
+
+**--xstats-reset**
+The xstats-reset parameter controls the resetting of extended port statistics.
+If no port mask is specified xstats are reset for all DPDK ports.
+
+**-m**: Print DPDK memory information.
