[libcamera-devel] [RFC PATCH 00/14] Preliminary FULL plumbing

[Paul Elder]

This patch series adds controls and plumbing necessary for 5 controls to
satisfy FULL requirements:
- AeLock
- AeEnable (AE_MODE)
- AwbLock
- AwbMode
- MaxLatency (SYNC_MAX_LATENCY)

Patch 1/14 has the plumbing for capability detection. It does not need
to be reviewed; it is only included for dependency resolution.

Patches 2/14 to 5/14 add the necessary controls.

Patches 2/14 and 6/14 to 9/14 plumb the controls into the HAL. They all
plumb into the static metadata, and only a few into the result metadata.

Patches 10/14 to 14/14 plumb the controls into the IPU3 pipeline
handler.

As for IPA capability discovery, I think we can simply do an extension
of what I have on 10/14 to 14/14 on IPU3, just one layer over.

I hope that the patches for the HAL plumbing can give us some insight to
the requirements of the refactor capability manager.

Paul Elder (14):
  android: Add infrastructure for determining capabilities and hardware
    level
  android, controls: Add and plumb MaxLatency control
  controls: Replace AeLocked with AeState, and add AeLock
  controls: Replace AwbEnable with AwbMode
  controls: Replace AwbLocked with AwbState, and add AwbLock
  android: Plumb AeEnable control
  android: Plumb AeLock control
  android: Plumb AwbMode control
  android: Plumb AwbLock control
  FULL: pipeline: ipu3: Set MaxLatency ControlInfo
  FULL: pipeline: ipu3: Set AeEnable ControlInfo
