Re: [linux-yocto] [PATCH 47/57] Basic perf support for axxia plaform block provided by LSI.

2014-03-24 Thread Svennebring, Jonas

Hi,

The basic support includes:
* Generic AXXIA SMON (Statistic Monitor) functionality.

* Support for Memory Controllers:
  - DDRC, DDR Controllers.
  - ELM, Encryption Memory Controllers .

*Preparation for support of:
  - PCX, integrated Ethernet switch.
  - VP, virtual pipeline packet processing engines.

Documentation, VP/PCX support as well as patch alignment with coming ARM L3$ 
and interconnect is in the workings.

Best Regards,

//Jonas

Can we get a short feature listing of what is included in the basic support ?

A summary here is fine, and perhaps a README or other perf documentation update 
as well.

Looks good. Thanks for the summary.

Charlie: can we capture this in the log ?
