 +==== Kernel Package Build Helpers ====
 +
 +The Pinebook Pro (RK3399 SoC) requires a firmware blob to be installed within the OS InitRD (see further down) in order to light up one of the display ports.
 +To facilitate this, a helper script is executed from the kernel.SlackBuild script when the OS InitRD is constructed.  This helper extracts the relevant firmware blob from the Slackware a/kernel-firmware package.

 +== Firmware within the OS InitRD ==
 +
 +The RockPro64 requires a small blob of firmware for one of the display drivers.
 +This is included within /lib/firmware/rockchip
 +
 +<note important>Only firmware that is 100% required at Kernel module load time is added to the OS InitRD in order to keep the size down and to reduce overlap between the Slackware a/kernel-firmware package.  Firmware for a display driver is a must.  Firmware for Bluetooth et al is not.</note>
