- Test --numa_node 0 case
- damo show features implementation
- collapse by time
- Implement min/max snapshot format keyword
- damo reclaim: add a command for basic investigation
- helps ensure DAMON_RECLAIM is working as expected
- helps reporting issue
- Handle _damon_sysfs file i/o error for unsupported kernel features and
conflicts with concurrent ones
- Optimize 'replay' performance
- An approach for 2 MiB-granularity page management didn't show improvement
- Optionally use C program like 'masim'
- Let 'replay' further parse vmas and alloc/release memory
- Unify wss and footprints report types
- Fixup 'damo show' on schemes_tried_regions unsupported kernels
- Either make the warning clear, or support it using trace points
- (https://github.com/awslabs/damo/issues/101)
- 'diagnose' command
- check if nr_regions in bound
- check if DAMOS quota is in control
- 'damo monitor'
- add option to add snapshot as (optional) alternate of heatmap
- Show temperature histogram on holistic report
- heatmap: Support interactive zoom in/out/scrolling
- Implement single report formatter
- Extend 'report access' format arguments for wss, memfootprint, etc
- Provide virtual memory mapping information
- shows when what virtual address has mappend and unmapped
- Implement an official feature to check if 'damo' supports the system
- 'damo diagnose --kernel_support'? Or, 'damo report damon --kernel_support'?
- Automatically translate single allow filter to reject filter
- Pending. Just warning might be sufficient.
- Show intervals auto-tuning status on 'report access'
- If the tuning is activated, show positive sample rate and current tuned intervals
- Update tuned intervals when getting snapshot, for only intervals auto-tuning
enabled contexts
- Warn or error recording when intervals auto-tuning enabled.
- Disabling auto-tuning is another option.
- damo report access: allow appending formats
e.g., damo report access --format_snapshot_tail_append '<access observation ratio>'
- damo report access: show '<access observation ratio>' by default if
auto-tuning ongoing
- do not update monitoring intervals when doing snapshot
- reverting auto-tuned intervals, so make it not well working...
- make 'damo report heatmap' better
- provide three regions heatmap by default, or notice their existence
- better document the hidden regions
- Deprecate old features
- Deprecate 'damo report raw'
- notified as will-be-removed by 2025-03-09
- Deprecate 'damo status'
- notified as will-be-removed by 2025-02-26
- Deprecate 'damo show'
- notified as will-be-deprecated by 2025-02-26
- Deprecate heats report type in favor of heatmap report type
- notified as will-be-deprecated by 2025-02-26
- Deprecate translate_damos (done.)
- Deprecate single line per-scheme (done. code moved to _damon_deprecated)
- Deprecate v1-v3 schemes (done. necessary code moved to _damon_deprecated)
- Deprecate python2 support (done. code moved to _damon_deprecated)
- Deprecate scheme subcommand
- Can be replaced by start or tune
- Deprecate old scheme usages in tests
- Deprecate DAMON results record binary format (done. code moved to
_damon_deprecated)
