hash: add lock-free r/w concurrency

Add lock-free read-write concurrency. This is achieved by the
following changes.

1) Add memory ordering to avoid race conditions. The only race
condition that can occur is -  using the key store element
before the key write is completed. Hence, while inserting the element
the release memory order is used. Any other race condition is caught
by the key comparison. Memory orderings are added only where needed.
For ex: reads in the writer's context do not need memory ordering
as there is a single writer.

key_idx in the bucket entry and pdata in the key store element are
used for synchronisation. key_idx is used to release an inserted
entry in the bucket to the reader. Use of pdata for synchronisation
is required due to updation of an existing entry where-in only
the pdata is updated without updating key_idx.

2) Reader-writer concurrency issue, caused by moving the keys
to their alternative locations during key insert, is solved
by introducing a global counter(tbl_chng_cnt) indicating a
change in table.

3) Add the flag to enable reader-writer concurrency during
run time.

Liang Ma [Fri, 19 Oct 2018 11:07:18 +0000 (12:07 +0100)]
power: add traffic pattern aware power control

1. Abstract

For packet processing workloads such as DPDK polling is continuous.
This means CPU cores always show 100% busy independent of how much work
those cores are doing. It is critical to accurately determine how busy
a core is hugely important for the following reasons:

   * No indication of overload conditions.

   * User does not know how much real load is on a system, resulting
     in wasted energy as no power management is utilized.

Compared to the original l3fwd-power design, instead of going to sleep
after detecting an empty poll, the new mechanism just lowers the core
frequency. As a result, the application does not stop polling the device,
which leads to improved handling of bursts of traffic.

When the system become busy, the empty poll mechanism can also increase the
core frequency (including turbo) to do best effort for intensive traffic.
This gives us more flexible and balanced traffic awareness over the
standard l3fwd-power application.

2. Proposed solution

The proposed solution focuses on how many times empty polls are executed.
The less the number of empty polls, means current core is busy with
processing workload, therefore, the higher frequency is needed. The high
empty poll number indicates the current core not doing any real work
therefore, we can lower the frequency to safe power.

In the current implementation, each core has 1 empty-poll counter which
assume 1 core is dedicated to 1 queue. This will need to be expanded in the
future to support multiple queues per core.

2.1 Power state definition:

LOW:  Not currently used, reserved for future use.

MED:  the frequency is used to process modest traffic workload.

HIGH: the frequency is used to process busy traffic workload.

2.2 There are two phases to establish the power management system:

a.Initialization/Training phase. The training phase is necessary
  in order to figure out the system polling baseline numbers from
  idle to busy. The highest poll count will be during idle, where
  all polls are empty. These poll counts will be different between
  systems due to the many possible processor micro-arch, cache
  and device configurations, hence the training phase.
  In the training phase, traffic is blocked so the training
  algorithm can average the empty-poll numbers for the LOW, MED and
  HIGH  power states in order to create a baseline.
  The core's counter are collected every 10ms, and the Training
  phase will take 2 seconds.
  Training is disabled as default configuration. The default
  parameter is applied. Sample App still can trigger training
  if that's needed. Once the training phase has been executed once on
  a system, the application can then be started with the relevant
  thresholds provided on the command line, allowing the application
  to start passing start traffic immediately

b.Normal phase. Traffic starts immediately based on the default
  thresholds, or based on the user supplied thresholds via the
  command line parameters. The run-time poll counts are compared with
  the baseline and the decision will be taken to move to MED power
  state or HIGH power state. The counters are calculated every 10ms.

3. Proposed  API

1.  rte_power_empty_poll_stat_init(struct ep_params **eptr,
uint8_t *freq_tlb, struct ep_policy *policy);
which is used to initialize the power management system.
 
2.  rte_power_empty_poll_stat_free(void);
which is used to free the resource hold by power management system.
 
3.  rte_power_empty_poll_stat_update(unsigned int lcore_id);
which is used to update specific core empty poll counter, not thread safe
 
4.  rte_power_poll_stat_update(unsigned int lcore_id, uint8_t nb_pkt);
which is used to update specific core valid poll counter, not thread safe
 
5.  rte_power_empty_poll_stat_fetch(unsigned int lcore_id);
which is used to get specific core empty poll counter.
 
6.  rte_power_poll_stat_fetch(unsigned int lcore_id);
which is used to get specific core valid poll counter.

7.  rte_empty_poll_detection(struct rte_timer *tim, void *arg);

hash: use partial-key hashing

This commit changes the hashing mechanism to "partial-key

This is  proposed in Bin Fan, et al's paper
"MemC3: Compact and Concurrent MemCache with Dumber Caching
and Smarter Hashing". Basically the idea is to use "xor" to
derive alternative bucket from current bucket index and
signature.

With "partial-key hashing", it reduces the bucket memory
requirement from two cache lines to one cache line, which
improves the memory efficiency and thus the lookup speed.

requests. Callers of rte_mp_request_sync() might check that
param afterwards and might read potentially unitialized memory.

The no-shconf check that makes us return early (with rc = 0) was
placed before the `reply` initialization. Fix this by making the
`reply` initialization occur first.

6 years agokvargs: fix processing a null list
Thomas Monjalon [Tue, 23 Oct 2018 16:01:40 +0000 (18:01 +0200)]
kvargs: fix processing a null list

In the doxygen description of rte_kvargs_process(), it is said:
If *kvlist* is NULL function does nothing.
It has been added by mistake here instead of rte_kvargs_free().
Anyway, null list should be correctly handled in both functions.

Comments are fixed in both functions and NULL handling is added
to rte_kvargs_process().

6 years agomem: fix resource leak

mem: fix resource leak

Segment preallocation code allocates an array of structures on the
heap but does not free the memory afterwards. Fix it by freeing it
at the end of the function, and changing control flow to always go
through that code path.
