Notes for AOSP on Samsung Exynos

• IMS wont work on SAMSUNG devices. SLSI IMS exists but is not compatible with Samsung modem firmware.
• Exynos devices do not use
  BOARD_KERNEL_CMDLINE
  . Instead, use
  CONFIG_CMDLINE
  and
  CONFIG_CMDLINE_EXTEND=y
  the kernel defconfig.
• Bootloader errors are logged to
  /proc/last_kmsg
• On most devices, you can use GCAM, with a few tweaks. HDR+ and Night Sight will probably not work. Use Samsung Camera Experiments. BSG MGC is the most stable and works on most devices. AGC and SGC are finnicky. For example, BSG works fine after patching camera libs(and disabling HDR+). AGC 9.4 doesnt seem to disable HDR+? Same with SGC

Note: I am fairly new to exynos, M34 being the first device I own. What I have put here is information collected (and probably misunderstood) by me, talking to other exynos devs.
