All,

Here is where we stand on the project at the end of the day on Thursday:

Progress since yesterday:

- As promised, Dmitry turned his attention to preparing a preliminary 5.15 kernel with his clock driver patches for Sightline testing. That kernel has been published on the following public branch and is ready for Sightline's initial testing:

https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/log/?h=release/db820c/qcomlt-5.15

Dmitry notes that this kernel should be passed the kernel parameter 'maxcpus=2'.

Work in Progress:

- With the initial kernel published, work will return to the CBF/CPR patches, which when complete will be published on a separate branch.

Planned Work:

- Finish the CBF special handling in the CPR driver
- Utilize CBF for CPUfreq scaling
- Consider utilizing CPR driver for the GPU regulator powerup
- Finalize extra corner cases in the CPR driver

- Support for Sightline as required.

Budget burn: Yesterday, Dmitry spent 1.5 hours on the project, equating to 0.2 person-days. This leaves 5.6 person-days (45.0 hours) remaining in the engineering budget. I spent .25 hours (for a running total of 3 hours including the kickoff meeting and project set-up), meaning 37% of the PM time has been consumed.

We feel we are still on-track to to deliver the expected outcomes within current budget. We are especially pleased that we have been able to deliver an initial, testable 5.15 kernel with over half of the engineering budget remaining, and we hope Sightline will be pleased with the results.

As always, if you have any questions or concerns please reach out at any time.

Kind regards,
Paul
