[PATCH v6 0/7] rust/hrtimer: Various hrtimer + time additions
Posted by Lyude Paul 2 months, 1 week ago
This is a collection of various bindings that I added to hrtimer when I
was originally getting it ready to be used in rvkms. I've mostly been
waiting for Andreas's hrtimer series to go upstream before submitting
these.

All of these are currently being used within rvkms for vblank emulation.

Previous versions:
  Version 1: https://lkml.org/lkml/2025/4/2/1474
  Version 2: https://lkml.org/lkml/2025/4/15/1750
  Version 3 (only a revision of one patch): https://lkml.org/lkml/2025/4/15/1780
  Version 4: https://lkml.org/lkml/2025/4/29/1715
  Version 5: https://lkml.org/lkml/2025/6/13/1785

Usage example:
 (keep in mind, I haven't rebased the example entirely - but the only
  differences there is a few comments)

  rust: hrtimer: Add forward_now() to HrTimer and HrTimerCallbackContext
  rust: time: Add Instant::from_nanos()

Thanks for working on this series!

I would really appreciate it if you put more details in your version
log. Everything takes longer when I have to search for changes between
versions.


Best regards,

JFYI - I did, I usually include my changelogs per-patch below the cutoff line
(---). But if you'd prefer I put them on the cover letter instead that's fine
by me
