No Simple Pipeline Handler Support

Description:

Arch doesn't enable the 'simple' pipeline handler in the libcamera package on x86 platforms. This makes libcamera (cam --list) unable to detect ipu6 cameras on Microsoft Surface Pro 8 devices. Please build libcamera with 'simple' pipeline handler enabled for x86 devices.

  • link to upstream bug report, if any: none

Steps to reproduce:

  1. Check to insure that intel_ipu6 camera kernel module is loaded using lsmod | grep ipu
  2. Check to see if libcamera detects the cameras in user space using cam --list
  3. Cameras are not detected.
