DAMO

./damo report access

整理下思路

For controlling DAMON (monitoring and monitoring-based system optimization)
- start, tune, and stop are included
For snapshot and visualization of DAMON’s monitoring results and running status
- show, and status are included
For recording the access monitoring results and utilizing the records
- record, report and replay are included
For more convenient use of damo
- version and fmt_json are included
replay 是什么个搞法

为什么使用 perf

perf_event_damon_aggregated = ‘damon:damon_aggregated’ perf_event_damon_monitor_intervals_tune = ‘damon:damon_monitor_intervals_tune’ perf_event_damos_before_apply = ‘damon:damos_before_apply’

	TP_printk("ctx_idx=%u scheme_idx=%u target_idx=%lu nr_regions=%u %lu-%lu: %u %u",
			__entry->context_idx, __entry->scheme_idx,
			__entry->target_idx, __entry->nr_regions,
			__entry->start, __entry->end,
			__entry->nr_accesses, __entry->age)

scheme 中的 filter 和 quota 是做什么的?

snapshot 是做什么的?

temperature

好像这个东西就可以了

不需要配置的那么复杂的

./damo report damon
kdamond 0
    state: on, pid: 10030
    context 0
        ops: vaddr
        target 0
            pid: 2958
        intervals: sample 5 ms, aggr 100 ms, update 1 s
        nr_regions: [10, 1,000]

这里的 1s 的 update 是什么意思?

admin/kdamonds/0/contexts/0/monitoring_attrs/intervals/update_us:1000000

而且这个完全不去使用 nr_regions 也是 nb 啊，似乎只有在需要获取数据的时候，才会读取这些东西。

似乎 scheme 这个东西完全没有作用啊

这里的 filter 的概念是什么?

是的确可以不去使用 perf 的

sudo ./damo start sudo ./damo report access

这个就可以直接看到原始数据了。 sudo ./damo report access –json

nb 的 auto-tuning 啊:

调试的小技巧

src/_damo_fs.py 中，将其修改为 debug_do_print = True 之后，可以看到和文件的交换过程是什么

开启一个 process 的跟踪之后，可以看到结果是这样的:

似乎是一个 context 下可以多一个

https://docs.kernel.org/admin-guide/mm/damon/usage.html#sysfs-schemes

是一个 context 监控一个 process 还是多个 process

似乎 damon 可以自动跟踪被 fork 出来的 process

为什么不可以支持细粒度的分析，既然 lru 都支持了。

似乎是可以慢慢解决的
