[libcamera-devel] [PATCH] android: nautilus: Add camera HAL configuration

[Umang Jain]

nautilus has two internal cameras, one UVC and one for the IPU3.
However, libcamera assumes all UVC cameras as 'external' hence, mark
the location of UVC camera in HAL configuration as 'external' too.

Note that the presence of UVC camera in camera HAL will complain:

> ERROR HAL camera_device.cpp:701 '\_SB_.PCI0.XHCI.RHUB.HS09-9:1.0-04f2:b647':
  Failed to map mandatory Android format IMPLEMENTATION_DEFINED (0x00000022): aborting
> ERROR HAL camera_hal_manager.cpp:153 Failed to initialize camera:
  \_SB_.PCI0.XHCI.RHUB.HS09-9:1.0-04f2:b647

This is related to a known issue of UVC cameras on HAL which do not
provide NV12 by default.

Also, if we don't mention the UVC camera in the config:

> ERROR HALConfig camera_hal_config.cpp:393 Camera
  '\_SB_.PCI0.XHCI.RHUB.HS09-9:1.0-04f2:b647' not described in the HAL
  configuration file
> ERROR HAL camera_device.cpp:701 '\_SB_.PCI0.XHCI.RHUB.HS09-9:1.0-04f2:b647':
  Failed to map mandatory Android format IMPLEMENTATION_DEFINED (0x00000022): aborting
> ERROR HAL camera_hal_manager.cpp:153 Failed to initialize camera:
  \_SB_.PCI0.XHCI.RHUB.HS09-9:1.0-04f2:b647
