I am currently experimenting with getting accelerated Xorg on mobile devices, and in this case, the subject is a Samsung Galaxy Tab S 10.5. So far, I've been able to boot into Debian natively with the LineageOS kernel using fbdev. Is it possible that if I install the appropriate r7p0 X11 userspace binaries for the kernel's GPU, essentially replacing the Android gralloc binaries, I can gain GPU accelerated Xorg on an Android kernel with armsoc? Would I have to patch the kernel drivers to work with Linux binaries or are Android and Linux userspace binaries interchangeable?
Drivers are not fully replaceble, Gralloc/ION are not the same as drm_buf.
