From: Felipe Balbi <felipe.balbi@xxxxxxxxxxxxx> Hi folks, I'm trying to enable the framebuffer on Microsoft Surface Duo. Looking through some internal docs, it came to my attention that the bootloader will fill up the framebuffer address and size to a memory node names splash_region. Adding the node, I can see the address of the framebuffer. Creating the relevant framebuffer device using simple-framebuffer, I can't see it working. Tried dd if=/dev/urandom of=/dev/fb0 and fb-test. None of which manage to get rid of what's already on the screen, put there by the bootloader (platform Logo). Wondering if any of you have seen a behavior such as this and how did you manage to get framebuffer working on SM8150 (I see at least Sony Xperia has the node).
