src/conio bitmap_con.c 1.41 1.42
Update of /cvsroot/sbbs/src/conio
In directory cvs:/tmp/cvs-serv24813
Modified Files:
bitmap_con.c
Log Message:
Fix bug in initialization of alternate fonts. There are two special values
for the four current fonts... -99 (uninitialized), and -1 (loaded font).
-99 was supposed to be automagically converted to CP437, but a bug in
revision 1.40 (Feb 27, 2015) made this not happen. As a result, the font
was copied from an index of -99 in the font data array. This was garbage
on some platforms and appears to have caused crashes in others.

In directory cvs:/tmp/cvs-serv11398
Modified Files:
bitmap_con.c
Log Message:
Added range checks when initializing textinfo.screenwidth and screeheight (don't wrap around if value is > 255) - presumably these textinfo struct members were left as unsigned chars (8-bits) to preserve compatiblity with legacy conio apps, but I'm not sure. Perhaps we could increase these to
at least 16-bit integers or bigger in the future, in which case these range checks would need to be removed or replaced.

src/conio bitmap_con.c 1.61 1.62
Update of /cvsroot/sbbs/src/conio
In directory cvs:/tmp/cvs-serv5244
Modified Files:
bitmap_con.c
Log Message:
Exciting new bitmap features
1) Fix last commit. Crashes/Video corruption resolved.
2) Add ccputs() and cputch() to ciolib. These take a colour value as their
first argument, which is a palette entry. They otherwise work the same
as their counterpart without the c prefix.
3) Add a flags member to vstat which needs to be set before loading a mode.
The only defined flag is currently VIDMODES_FLAG_PALETTE_VMEM.
4) If VIDMODES_FLAG_PALETTE_VMEM is set, allocate 32-bit arrays for the
foreground and background palette entries for each cell.
5) Have bitmap_con.c use the palette vmem flag.
6) Have movetext() copy the palette entries along with the regular vmem.
In theory now, bitmap_con.c will handle giant colour palettes, and anything that uses movetext() (ie: scrolling) will maintain the colours.
gettext() and puttext() unfortunately can not access the palette memory... we'll see if we need extended replacements for them or not.

Modified Files:
src/conio/bitmap_con.c
Log Message:
Push update_pixels down and force a redraw on font change.
update_pixels should only be set when at least one pixel has
actually been changed... setting it when pixels have not been
changed causes unneeded screen updates.
Previously, a font change asserted (incorrectly) that the pixels in
the screen had been modified, so the change would occur at the end
of the next blink cycle when alt fonts are checked. Now it
requests a full redraw from vmem when a font is changed, which will
trigger a redraw the next time the blinker thread triggers (~5ms).

Modified Files:
src/conio/bitmap_con.c
Log Message:
Another large speedup... only update bitmap when drawing a frame
Previously, every change would be flushed through to the bitmap, now
it only flushes before a frame is sent to the driver, or when specific
things (like setting pixels) occur.
This about doubles the throughput again, running the test at 11
seconds (started at 179). At a 16× speedup now from when I started.
This can now display at about 10Mbps, which is still kinda slow,
but at least it's not completely terrible anymore.
This could likely be improved by better timing of the frame
generation... it tries to hot 100Hz right now, which is a bit
excessive.

Log Message:
Another big speedup...
Since we update the bitmap before drawing a frame now, we can just
mark the cells incorrectly moved by advancing the bitmap ringbuffer
as dirty and known they'll be redrawn.
This gets rid of the memmove on full-width scrolling, and gets us
into the 6s range.

Fix major performance regression in RIP rendering
A high number of RIP commands use setpixel(), and it was updated
to scan the whole vmem for changes on each call. Now we just extract
the part that is relevant and only update the one cell if needed.
This also adds parameter validation to bitmap_setpixel() which can
prevent some memory corruption and crashes.

Log Message:
Fix up cursor and blinking rates, step 1...
For "PC" modes, cursor blinked at 1/16th of the VSYNC rate, so use
the CGA timings, where were generally the slowest of the bunch...
This means cursor blink at 3.745Hz, and character blink at 1.8725Hz.
For Prestel, character blink was 0.75Hz with a 3:1 On:Off ratio.
The cursor on the other hand was 1/32th the VSYNC and was generally
PAL, so 1.5625Hz.
I still need to dig into C64 and Atari modes, because they're likely
way off now (assuming either supports blinking).

Modified Files:
src/conio/bitmap_con.c
Log Message:
Adjust Prestel cursor flash.
It appears that it flashes at 1.5Hz with the off period synchronized
to the blinking text off period.
Still no idea what generates it though.

Synchronize blink rate to real Model B
Keyop provided a video of flashing stuff for me. This now
synchronizes with that video. Can't get any better than that.

Modified Files:
src/conio/bitmap_con.c
Log Message:
Split the happy path font rendering into separate function
And merge the single/double height ones into the same function.
Normalize all the types while I'm here.
With this, the happy path draw_char_row_fast() is very simple and
easy to keep updated, and all of the complexity goes into
draw_char_row_slow().
There seems to be around a 20% performance difference between them,
but it can be hard to tell for sure because of the time spent
cheating.
Note that it doesn't appear to be worth cheating if we're going fast,
but that's getting a bit too deep for my tastes.

Log Message:
Add silly check to make coverity happy.
This is in the fastpath, but it's on the slow side where I don't
mind the occasional extra silly check.
