|
||||
.SH NAME
|
||||
testaccel \- test the old style blitter functions and vga_ext_set()
|
||||
.SH SYNOPSIS
|
||||
|
||||
.BI "testaccel [ -nowait ] [ { all | " videomodes "... } ]
|
||||
|
||||
.SH DESCRIPTION
|
||||
Program to test the old blitter functions in a screen mode. Checks
|
||||
the 8-bit wide color lookup tables on Mach32's with type 2 DACs
|
||||
as well.
|
||||
[I think '6bpp' and '8bpp' are silly names for the 8-bit
|
||||
LUT thing -- bpp is bits per pixel, in the framebuffer - HH :-)]
|
||||
|
||||
After each test it waits for a key press except when
|
||||
.B -nowait
|
||||
is
|
||||
given.
|
||||
|
||||
You can specify names of modes to test on the command line
|
||||
or specify
|
||||
.B all
|
||||
to loop over all svgalib modes.
|
||||
|
||||
The program will run on any card, however, most of the tests can
|
||||
only be performed on a Mach32.
|
||||
|
||||
The subtest are in turn:
|
||||
|
||||
.TP
|
||||
.B 1 -
|
||||
For each 256 color mode the program sees if it is possible to
|
||||
enable a special mode with 8 bits per color in the RGB lookup
|
||||
table. If so, for example 256 different shades of blue can
|
||||
be implemented.
|
||||
The program displays as much blue shades as possible in a shade
|
||||
from dark (left) to bright (right) and some text in an
|
||||
opposite direction on top of it. In case 56 different shades
|
||||
are supported, the screen is divided and shows a rough 64 shades
|
||||
scale (ordinary vga) on top and the smooth shade below.
|
||||
Right now 256 different shades are only possible on a Mach32 with
|
||||
RAMDAC of type 2.
|
||||
For modes with few pixels only, the program might fail to print
|
||||
the text properly and will 'wrap' it around the screen edges.
|
||||
.TP
|
||||
.B 2 -
|
||||
Draws a bouncing 'linux' logo stopping after a fixed amount of
|
||||
1 pixel steps. Uses
|
||||
.BR vga_bitblt (3)
|
||||
on the image plus a one pixel
|
||||
outline in border color to move the pixel around the screen.
|
||||
The Mach32 is
|
||||
.B very
|
||||
fast in this discipline.
|
||||
.TP
|
||||
.B 3 -
|
||||
Draws filled rectangles using
|
||||
.BR vga_fillblt (3).
|
||||
At first a series
|
||||
of larger to smaller centered rectangles is drawn to fill the
|
||||
screen.
|
||||
For 256 or less color modes these will use a sequence of 256
|
||||
random colors. For 32K or more color modes it will use colors
|
||||
0 up too, however, you'll usually just see a repeating series
|
||||
of blues (limitations of monitor/human eye, the blue's differ
|
||||
not enough for the eye to see). Then a bunch of random boxes
|
||||
in random places is drawn overwriting each other.
|
||||
The Mach32 is
|
||||
.B very
|
||||
fast in this discipline.
|
||||
.TP
|
||||
.B 4 -
|
||||
Draws small fish bitmaps and then larger linux logos in random
|
||||
positions using
|
||||
.BR vga_imageblt (3).
|
||||
They just overlap each other
|
||||
The Mach32 is poor in this discipline. If you have a linear
|
||||
frame buffer enabled, it is used instead to perform this function
|
||||
(even if the program does not use a linear frame buffer otherwise).
|
||||
Usually this is twice as fast for Mach32.
|
||||
.TP
|
||||
.B 5 -
|
||||
Use
|
||||
.BR vga_hlinelistblt (3)
|
||||
o do some simple polygon fills: squares,
|
||||
circles, diamonds of random sizes, positions and colors. Again,
|
||||
the Mach32 is
|
||||
.B very
|
||||
fast in this discipline, but somehow slowed
|
||||
down by the imperfect prototype of this function. Again,
|
||||
the polygons just overlap each other.
|
||||
|
||||
The resp. tests will only be performed where supported by the
|
||||
hardware. For Mach32 this means only SVGA 256, 32K, 64K color modes.
|
||||
The linear frame buffer emulated
|
||||
.BR vga_imageblt (3)
|
||||
works for all SVGA modes
|
||||
though.
|
||||
.P
|
||||
|
||||
The program prints the number of pixels drawn and the time required
|
||||
plus the resulting rate of pixels per second. For Mach32 the rate
|
||||
depends on the amount of screen accesses (2 per pixel move for
|
||||
.BR vga_bitblt (3),
|
||||
1 per pixel move for
|
||||
.BR vga_fillblt "(3) and "
|
||||
.BR vga_hlinelistblt (3);
|
||||
also twice bytes
|
||||
are affected for 32K, 64K color modes). On a non VRAM card you'll
|
||||
also note the effect of the memory access caused by the generation
|
||||
of the video frames (more colors/rez/sync rates => less speed).
|
||||
Also, higher modes draw more pixels per call, thus less call and
|
||||
setup overhead.
|
||||
|
||||
Here are the rates for my card on an almost idle 486 EISA system
|
||||
which should be fairly optimal (2MB VRAM EISA Mach32) except maybe
|
||||
the linear frame buffer emulated imageblt which might be faster on
|
||||
PCI card:

This demo is part of svgalib and can be found in the
|
||||
.I demos/
|
||||
subdirectory of the original svgalib distribution. However, it is not installed in the system
|
||||
by default, s.t. it is unclear where you can find it if your svgalib was installed by some
|
||||
linux distribution. Even then, when you have the demo on your system, you probably won't have
|
||||
the sources s.t. it is only of limited use for you.
|
||||
|
||||
In case of any such problem, simply get an svgalib distribution from the net. You even
|
||||
don't need to install it. Just
|
||||
.B make
|
||||
in the
|
||||
.I demos/
|
||||
subdirecty. As of this writing,
|
||||
.I svgalib-1.2.12.tar.gz
|
||||
is the latest version and can be retrieved by ftp from
|
||||
.IR "sunsite.unc.edu" " at " "/pub/Linux/libs/graphics"
|
||||
and
|
||||
.IR "tsx-11.mit.edu" " at " "/pub/linux/sources/libs"
|
||||
which will most probably be mirrored by a site close to you.
