Subject: Re: [dpdk-dev] [PATCH v3 0/2] Timer library changes
Date: Wed, 19 Dec 2018 04:35:36 +0100	[thread overview]
Message-ID: <1740997.qR0t5JnZGs@xps> (raw)

13/12/2018 23:26, Erik Gabriel Carrillo:
> This patch series modifies the timer library in such a way that
> structures that used to be statically allocated in a process's data
> segment are now allocated in shared memory.  As these structures contain
> lists of timers, new APIs are introduced that allow a caller to specify
> the particular structure instance into which a timer should be inserted
> or from which a timer should be removed.  This enables primary and
> secondary processes to modify the same timer list, which enables some
> multi-process use cases that were not previously possible; e.g. a
> secondary process can start a timer whose expiration is detected in a
> primary process running a new flavor of timer_manage().
> 
> The original library API is mostly unchanged, though implementations are
> updated to call into newly added functions with a default structure
> instance ID that provides the original behavior.  New functions are
> introduced to enable applications to allocate structure instances to
> house timer lists, and to reference them with an identifier when
> starting and stopping timers, and finally, to manage the timer lists
> referenced with an identifier.
> 
> My initial performance testing with the "timer_perf_autotest" test shows
> no performance regression or improvement, and inspection of the
> generated optimized code shows that the extra function call gets inlined
> in the functions that now have an extra function call. 
> 
> Depends on: https://patches.dpdk.org/patch/48417/
> 
> Changes in v3:
>  - remove C++ style comment in first patch in series (Stephen)
> 
> Changes in v2:
>  - split these changes out into their own series
>  - version the symbols where the existing ABI was updated, and
>    provide alternate implementation with behavior equivalent to original
>    behavior. Validated ABI compatibility with validate-abi.sh
>  - refactor changes to simplify patches
> 
> Erik Gabriel Carrillo (2):
>   timer: allow timer management in shared memory
>   timer: add function to stop all timers in a list
>
