# verify-x68000-scb.sh - SCB gate for the X68000: proves that the per-band
|
|
# palette reloads the text-plane present depends on land where they must, on
|
|
# a screen that changes palette 147 times a frame.
|
|
#
|
|
# The X68000 port presents to the text plane, which has ONE 16-entry palette,
|
|
# so it honors the SCB by reloading that palette as the beam scans: a CRTC
|
|
# raster interrupt (src/x68000/jlX68kRasterIsr.s) stores a band's sixteen
|
|
# colors in the horizontal blanking before the band's first line. Each reload
|
|
# has a window of about 400 dots (~18 us): after the last stage pixel of the
|
|
# line above and before the first stage pixel of the band. Land early and the
|
|
# end of the line above shows the new colors; land late and the start of the
|
|
# band shows the old ones; miss and the whole band does.
|
|
#
|
|
# Boots Human68k headless under MAME with SCB.X (examples/scb): all sixteen
|
|
# palettes, every color distinct per palette, a change on every line for 128
|
|
# of the 200 lines, irregular runs for the rest, 20 stripes using every color
|
|
# on every line, the whole stage redrawn and every palette set again on every
|
|
# pass. Once the stripes are up and have settled, the Lua below taps every
|
|
# write to the text palette ($E82200), to the raster compare (CRTC R09), to
|
|
# MFP ISRA (the interrupt's exit) and every read of the $138 vector (its
|
|
# entry), timestamped on the emulated clock -- MAME's x68000 runs the
|
|
# cycle-exact 68000 core, so a write's timestamp is its bus cycle -- and
|
|
# converts each to a beam position with the screen's own timing. It then
|
|
# checks CAPTURE whole frames, computing what every stage line shows from the
|
|
# program's SCB and palette rules (the same rules as examples/scb/scb.c, not
|
|
# the output):
|
|
#
|
|
# timeline the palette in effect at each line's first stage pixel is that
|
|
# line's palette, and no palette write lands between its first and
|
|
# last stage pixel. This is what a CRT shows: a palette write takes
|
|
# effect at once. Every band start's reload is also measured: how
|
|
# long after the last stage pixel of the line above it began, and
|
|
# how long before the band's first stage pixel it finished.
|
|
# bitmap MAME's own rendering, read back with screen:pixels() on SNAPSHOTS
|
|
# frames, shows each line in its palette -- or, only where the next
|
|
# line starts a band, partly in the next line's: MAME draws a line
|
|
# when the NEXT line's display begins (x68k_crtc.cpp hsync ->
|
|
# update_partial(scan - 1)), so a reload that lands correctly in
|
|
# the blanking before a line is drawn onto the line above it, unless
|
|
# a raster interrupt drew that line first (raster_irq). MAME's
|
|
# bitmap therefore cannot place a reload to the line; the timeline
|
|
# can. This check catches gross misplacement independently of the
|
|
# taps.
|
|
# exit after ESC the program exits and gives the $138 vector and MFP
|
|
# channel 14 back -- and the two clock vectors it held while it
|
|
# ran, which are checked then: $114 (jlX68kTickIsr, chained onto
|
|
# Human68k's Timer C) and $134 (jlX68kVdispIsr, the frame counter
|
|
# _VDISPST installs, with MFP channel 13 enabled).
|
|
#
|
|
# It also reports the interrupt's cost (time inside it per frame), the latency
|
|
# from each raster match to the vector fetch, and the slack of the compare
|
|
# write the interrupt's timing rests on (jlX68kRasterIsr.s step 2).
|
|
#
|
|
# Human68k's Timer C tick runs throughout, and text is typed during the whole
|
|
# capture so the IOCS keyboard interrupt runs too: both are MFP interrupts at
|
|
# IPL 6, like the raster interrupt, and a raster match that falls inside one of
|
|
# them is taken late (the Timer C dispatcher used to make reloads miss their
|
|
# line; see src/x68000/jlX68kTickIsr.s). The DMAC-driven ADPCM path is not
|
