I'm planning on 1 hour for this meeting.

The agenda for the meeting (and where we'll keep the minutes) is here:

The agenda for the July 22 meeting will be available in the above document before the call.
This is what I've got so far:

- ELC boot-time post-mortem
   - What ideas should we follow up on to advance upstream?

  - Status of patches or docs being considered for upstream
    - print initlevel
    - bootstage stash driver
    - show_delta 2.0
    - deferred initcalls
    - better probe details (function name, to map to source line)
    - pre-timer init cycle count durations (and tool)
    - anything outstanding for deferred memory init?
    - documentation or tuning guide?

- Round-table of on-going work
     - Tim currently working on:
         - boot time early cycle counts (Tim)
         - boot-time regression test
         - mapping printks and initcalls to source lines, to accumulate boot time per Linux sub-system
   - boot caching (The Good Penguin work)
   - boot-time data wiki (Tim)
   - Unified Boot Log (Vishnu, TI)
   - elinux wiki Boot-Time pages
      - https://elinux.org/Boot_Time_Project_Ideas
    - Automatically reducing kernel configuration (Michael)
    - Android working on parallelized module loading (Saravana)
    - some udev integration with systemd (Federico)
     
 - Conference and meetups:
   - ELC 2025 - June 23-25, Denver, USA - pretty good lineup of boot-time topics
     - presentations and videos are now available: https://elinux.org/ELC_2025_Presentations
   - ELCE 2025 - August 25-27, Amsterdam, The Netherlands
   - LPC 2026 - December 11-13, 2025, Tokyo, Japan

Next meeting: August 26th falls during Embedded Linux Conference Europe 2025,
so we'll skip that as a call.  If there's enough interest, we might be able to schedule an unconference
session for boot-time discussions in Amsterdam, for those present.
Our next call will likely be September 23rd.
