From 432d59c56ef8a8eaefd847a40a01439e32317bff Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Thu, 7 Oct 2021 23:12:51 +0100 Subject: macfb: fix 24-bit RGB pixel encoding According to Apple Technical Note HW26: "Macintosh Quadra Built-In Video" the in-built framebuffer encodes each 24-bit pixel into 4 bytes. Adjust the 24-bit RGB pixel encoding accordingly which agrees with the encoding expected by MacOS when changing into 24-bit colour mode.
