As announced in 20.08 release notes, the terms for lcore role
will change in 20.11 release.

This is a project wide patchset to terminolgy used for DPDK lcore.
The term "master" referring to lcore is replaced with "main" and
"slave" lcore is replaced with "worker" lcore.

This is most visible in API for rte_get_master_lcore() which is
replaced with rte_get_main_lcore(). And the macros for iterating
over lcores are replaced as well.

The first patch introduces a way to mark macro's as deprecated
as well.

Stephen Hemminger (15):
  eal: add macro to mark macros as deprecated
  eal: rename lcore word choices
  rte_power: replace rte_master_lcore with rte_main_lcore
  drivers: replace master lcore with main lcore
  doc: replace master lcore with main lcore
  app/test: replace uses of master/slave
  app/test-pmd: replace master lcore with main lcore
  app/test-eventdev: replace use of master lcore with main lcore
  app: replace references to master/slave
  examples: replace use of master with main
  examples/multi_process: replace references to master/slave
  examples/performance-thread: replace reference to master lcore
  examples/qos: replace references to master
  examples/ipsec-secgw: replace master lcore with main lcore
  examples: replace master lcore with main lcore

Add a macro that causes GCC and CLANG to emit a warning when
a deprecated macro is used.

Replace master lcore with main lcore and
replace slave lcore with worker lcore.

Keep the old functions and macros but mark them as deprecated
for this release.

The "--master-lcore" command line option is also deprecated
and any usage will print a warning and use "--main-lcore"
as replacement.

+  The iterator for worker lcores will also change:

As announced in 20.08 release notes, the terms for lcore role
will change in 20.11 release.

This is a project wide patchset to terminolgy used for DPDK lcore.
The term "master" referring to lcore is replaced with "main" and
"slave" lcore is replaced with "worker" lcore.

This is most visible in API for rte_get_master_lcore() which is
replaced with rte_get_main_lcore(). And the macros for iterating
over lcores are replaced as well.

The first patch introduces a way to mark macro's as deprecated
as well.

v2
   - fix more places found by Anatoly and grep
   - add coding style update
   - add memif changes

Update the coding style document to include a policy against
introducing new master/slave usage. This is taken from the similar
place in the Linux kernel coding style.

 DPDK also provides an optimized way to store elements in lockless rings.
 This should be used in all data-path code, when there are several consumer and/or producers to avoid locking for concurrent access.
 
+Naming
+------
+
+For symbol names and documentation, new usage of
+'master / slave' (or 'slave' independent of 'master') and 'blacklist /
+whitelist' is not allowed.
+
+Recommended replacements for 'master / slave' are:
+    '{primary,main} / {secondary,replica,subordinate}'
+    '{initiator,requester} / {target,responder}'
+    '{controller,host} / {device,worker,proxy}'
+    'leader / follower'
+    'director / performer'
+
+Recommended replacements for 'blacklist/whitelist' are:
+    'denylist / allowlist'
+    'blocklist / passlist'
+
+Exceptions for introducing new usage is to maintain compatiablity
+with an existing (as of 2020) hardware or protocol
+specification that mandates those terms.

Replace master lcore with main lcore and
replace slave lcore with worker lcore.

Keep the old functions and macros but mark them as deprecated
for this release.

The "--master-lcore" command line option is also deprecated
and any usage will print a warning and use "--main-lcore"
as replacement.

Replace master/slave terms in this driver.

The memory interface drivers uses a client/server architecture
so change the variable names and device arguments to that.

The previous devargs are maintained for compatiablity, but if
used cause a notice in the log.

As announced in 20.08 release notes, the terms for lcore role
will change in 20.11 release.

This is a project wide patchset to terminolgy used for DPDK lcore.
The term "master" referring to lcore is replaced with "main" and
"slave" lcore is replaced with "worker" lcore.

This is most visible in API for rte_get_master_lcore() which is
replaced with rte_get_main_lcore(). And the macros for iterating
over lcores are replaced as well.

The first patch introduces a way to mark macro's as deprecated
as well.

Note: this patch will fail checkpatch because current versions
of checkpatch flag use of master/slave as an error. Also,
until the whole patch series is applied, the build will generate
non-fatal warnings.

v3
   - incorporate still more places where master/slave was still used

v2
   - fix more places found by Anatoly and grep
   - add coding style update
   - add memif changes

Update the coding style document to include a policy against
introducing new master/slave usage. This is taken from the similar
place in the Linux kernel coding style.

 DPDK also provides an optimized way to store elements in lockless rings.
 This should be used in all data-path code, when there are several consumer and/or producers to avoid locking for concurrent access.
 
+Naming
+------
+
+For symbol names and documentation, new usage of
+'master / slave' (or 'slave' independent of 'master') and 'blacklist /
+whitelist' is not allowed.
+
+Recommended replacements for 'master / slave' are:
+    '{primary,main} / {secondary,replica,subordinate}'
+    '{initiator,requester} / {target,responder}'
+    '{controller,host} / {device,worker,proxy}'
+    'leader / follower'
+    'director / performer'
+
+Recommended replacements for 'blacklist/whitelist' are:
+    'denylist / allowlist'
+    'blocklist / passlist'
+
+Exceptions for introducing new usage is to maintain compatiablity
+with an existing (as of 2020) hardware or protocol
+specification that mandates those terms.

Replace master lcore with main lcore and
replace slave lcore with worker lcore.

Keep the old functions and macros but mark them as deprecated
for this release.

The "--master-lcore" command line option is also deprecated
and any usage will print a warning and use "--main-lcore"
as replacement.

  To: dev; +Cc: Stephen Hemminger

Replace master/slave terms in this driver.

The memory interface drivers uses a client/server architecture
so change the variable names and device arguments to that.

The previous devargs are maintained for compatiablity, but if
used cause a notice in the log.
