[src/trunk]: src/sys/arch/hp300/dev Add bitmap access ops support for SGC CRX...
details: https://anonhg.NetBSD.org/src/rev/4082af84955a
branches: trunk
changeset: 948264:4082af84955a

description:
Add bitmap access ops support for SGC CRX (A1659-66001) framebuffer.
Also modify existing 425e EVRX attachment to use updated MI sti(4) ops
more efficiently.
The Xorg server and mlterm-wscons (that support wsdisplay bitmap) work
fine on SGC hp425t.
No particular comments on port-hp300@ and port-hppa@:

https://mail-index.netbsd.org/port-hp300/2020/12/20/msg000185.html
Special thanks to Miod Vallat again, for contributing the SGC CRX
framebuffer with the SGC connector and flexible cable for HP9000/425t.
He also contributed DIO-II "Hyperion" monochrome framebuffer and
1 plane grayscale SGC GRX (A1924-66001), and I've confirmed hyper(4)
just works even with Xorg server. I will try GRX as the next project.
