rpi3 bare metal interrupt example

This is an example to demonstrate how to have a timer execute in EL1 on a raspberry pi 3 in bare metal assembly.

Created demo to support the user question in https://forums.raspberrypi.com/viewtopic.php?t=365600

Generate kernel with:

$ aarch64-none-elf-as -o rpi3-interrupt-demo.o rpi3-interrupt-demo.s 
$ aarch64-none-elf-ld --no-warn-rwx-segments -N -Ttext=0x0 -o rpi3-interrupt-demo.elf rpi3-interrupt-demo.o
$ aarch64-none-elf-objcopy --set-start=0x0 rpi3-interrupt-demo.elf -O binary rpi3-interrupt-demo.img

Taskcluster clean up

Worker inconsistencies

  • Two mechanisms for create generic worker windows AMIs (OCC and generic-worker scripts)
  • Config differences between worker types (C: drive vs Z: drive etc)
  • Payload differences between workers
  • Payload differences between platforms:
    • Automatically set env vars (e.g. TASKCLUSTER_*)
    • Mounts
    • Caolescing
  • Artifact format

Login v3

Goals

  • Users should be able to login easily to the tools site to carry out day-to-day tasks.
  • Users should be able to create and manage limited-access permanent credentials for use in their own automation
  • Permanent credentials tied to users should be disabled when those users lose the relevant permissions
  • All services have a consistent, reliable way to log who or what is making a particular request.
