Revision	Date	Author	Comments
1.7	06-Dec-2024	macallan	allow placement of the glyph cache anywhere in VRAM mostly for weird HP graphics hardware that has usable off-screen memory to the right of the visible screen instead of below it
1.6	08-Jun-2023	macallan	branches: 1.6.6; allow drivers to specify horizontal alignment of glyph cache cells for things like SX which have alignment restrictions
1.5	02-Jun-2017	macallan	branches: 1.5.42; make glyph caches reconfigurable
1.4	04-Oct-2012	macallan	branches: 1.4.14; allow caching of glyphs with attributes other than the default while there, also add support for underlined characters
1.3	22-Apr-2012	uebayasi	branches: 1.3.2; Add newline at end of file; fix ALL build for me.
1.2	19-Apr-2012	macallan	no need to convert cell number to coordinates every time we draw a glyph from cache - just stick the coordinates directly into the map
1.1	16-Feb-2012	macallan	branches: 1.1.2; 1.1.4; generic support for caching glyphs in video memory for speeding up anti-aliased fonts on slow CPUs

1.5.42.1	05-Jul-2023	martin	Pull up following revision(s) (requested by abs in ticket #224): sys/dev/wscons/wsdisplay_vconsvar.h: revision 1.34 sys/dev/wscons/wsdisplay_glyphcachevar.h: revision 1.6 sys/arch/sparc/dev/cgfourteen.c: revision 1.94 sys/arch/sparc/dev/cgfourteen.c: revision 1.95 sys/dev/sbus/mgx.c: revision 1.21 sys/dev/sbus/mgx.c: revision 1.22 sys/dev/sbus/mgx.c: revision 1.23 sys/dev/wscons/wsdisplay_vcons.c: revision 1.65 sys/dev/wscons/wsdisplay_vcons.c: revision 1.66 sys/dev/wscons/wsdisplay_glyphcache.c: revision 1.12 sys/arch/sparc/dev/sxvar.h: revision 1.5 sys/arch/sparc/dev/sx.c: revision 1.6 sys/arch/sparc/dev/sx.c: revision 1.7 make vcons_putchar_buffer() return a flag indicating if anything actually changed, skip the actual drawing op if nothing did add flags for drivers to requesr R2L bit/byte-ordered fonts, default to L2R, chack them in vcons_load_font() instead of just trusting that we'd get what we need initialize the diagnostic register with the value suggested by the SunOS header. This sets a bunch of undocumented bits and yields a 10% speed increase when rendering antialiased text. use macros compatible with xf86-video-suncg14 to issue SX instructions much more readable, alignment weirdness is handled automatically and code is interchangable allow drivers to specify horizontal alignment of glyph cache cells for things like SX which have alignment restrictions add counter to periodically drain the instruction queue in order to avoid stalling the MBus during long SX operations adapted from xf86-video-suncg14 - use sx_wait() to avoid stalling the MBus - request 32bit alignment for glyphcache cells wait for the engine to go idle before issuing rectfill commands we get occasional overlap with blit commands if we just wait for fifo slots needs further investigation, it is possible that not all writes to drawing engine registers are pipelined and of course we don't have docs following a hunch... - cache DEC and FG registers, only write them if the value actually changes - wait for the engine to go idle before writing DEC - wait for FIFO slots on everything else with this we avoid waiting if possible and still avoid overlapping blit and fill commands
