The IRQs will run on whichever core calls this function (this is why it's called separately from dvi_init)

Setup first set of control block lists, configure the control channels, and trigger them. Control channels will subsequently be triggered only by DMA

Make a sequence of paced transfers to the relevant FIFO

Set up control channels to make transfers to data channels' control registers (but don't trigger the control channels -- this is done either by data c

Always-inline else the compiler does rash things like passing structs in memory

result can not be == left or right

Sprites may have an array of metadata on the end. One word per line, encodes first opaque pixel, last opaque pixel, and whether the span in between is

Set up an interpolator to follow a straight line through u,v space

Set up an interpolator to generate pixel lookup addresses from fp1616 numbers in accum1, accum0 based on the parameters of sprite sp and the size of t

User is describing a sequence of transformations from texture space to screen space, which are applied by premultiplying a column vector. However, har

a * b * 2

Appears as a counterclockwise rotation (when viewed from texture space to screen space) Units of angle are 256 = one turn

Pixel format RGB222

This takes a 24-bit (RGB 888) colour palette and makes palettes of TMDS symbols suitable for performing fullres encode. The TMDS palette buffer should

This takes a 16-bit (RGB 565) colour palette and makes palettes of TMDS symbols suitable for performing fullres encode. The TMDS palette buffer should

Ugh copy/paste but it lets us garbage collect the TMDS stuff that is not being used from .scratch_x

Version where each record in q_colour_valid is one scanline:

Encoding a single channel at a time is not the most efficient way to use this hardware, because it means we read the colour buffer multiple times, but
