All,
As we discussed in yesterday’s status meeting, There have been some unexpected complexities in delivering all of the components of the 5.15 kernel as planned. Let me give a quick status update on where we are and what we recommend continuing with.
Still in progress and yet to be delivered pending testing: cpufreq and cpuidle changes. With the fixes he has, Dmitry is able to boot and run the board with 4 cores and without the RCU messages previously seen.
With the remaining hours left in the original contract, Dmitry can work on the CPR and voltage regulator support issues which include additional GPU support, but those fixes will take more effort than currently remains in the budget. Dmitry currently estimates that full regulator support will require 5-10 more working days of effort. At present, there are roughly 3 days of effort left in the original budget, and at least one of those days will likely be consumed with cpufreq testing, branch creation, and support for SightLine testing.
Dmitry also believes that the fixes to CPR and the regulators will correct the spurious rebooting issue SightLine is seeing in one of the test images provided to date.
Linaro recommends that the agreement be extended out for an additional 10 days of budget in order to complete the CPR and regulator work. This should allow us to deliver the remaining work to provide SightLine with a 5.15 kernel fit for purpose on your production platforms.
If you agree with this approach, and I believe you have agreed in principle pending details, then I will forward an extension of the first contract for your review and signature.
As always, please do not hesitate to contact me with any questions or concerns.
Thank you.
Kind regards,
Paul
