What doesn't work well
- I had to disable -Werror in order to compile the kernel
- initfs hook is not executed
- Splash screens don't work and I cannot get framebuffer working in initramfs
- Screen is black after I've entered the password. Workaround:
sh /etc/postmarketos-mkinitfs/hooks/00-device-motorola-titan.sh`
- Cannot boot if kernel is XZ-compressed (it boots if you build it using Android's build system)
- flash_kernel: boot image is too big
- wifi: requires wcnss-service (see issue #373 and the wiki page Qualcomm MSM Interface).
- show_splash
# From initramfs /tmp # show_splash splash1.ppm.gz fbsplash: short read
