mm.c - dumb build thing...

Dom — Sun, 05 Oct 2003 05:47:36 -0000

in kos 1.2.0, while compiling kos under debian woody i
got an error about DBG_DEAD not being found in
kernel/arch/dreamcast/kernel/mm.c

adding #include <stdio.h> at the top of mm.c fixed it

fs_iso9660: trailing '.' after filenames returned by readdir

Walter van Niftrik — Sun, 26 Jan 2003 03:25:27 -0000

This isn't really a bug, but it would be nicer if
fn_postprocess() would strip off the trailing '.' that
appears after filenames without extension on some cd's.
Most of the other fs_iso9660 code has workarounds for
this, but iso_readdir returns filenames with the '.'
still intact.

Typo in vmu_pkg_crc()

Anonymous — Tue, 07 Jan 2003 20:29:26 -0000

There is a small typo in file vmu_pkg.c, function
vmu_pkg_crc().

This line:

n = (n << 1) ^ 4128;

should read

n = (n << 1) ^ 4129;

as described on Marcus' website.

const char string parameter

Jonas Hultén — Wed, 06 Nov 2002 15:36:04 -0000

There is a function in the ogg vorbis code that looks like
this:

int sndoggvorbis_start(char *filename,int loop);

The filename parameter should be declared with const
since it won't be changed.

gettimeofday()

Anonymous — Fri, 11 Oct 2002 12:32:29 -0000

gettimeofday() advances 2 seconds per second.

The current implementation:

timer_ms_gettime(&s, &m);
tv->tv_sec = rtc_unix_secs() + s;
tv->tv_usec = m * 1000;

Both timer_ms_gettime() and rtc_unix_secs() are
'running'. Maybe rtc_unix_secs() should be replaced by
a value that's obtained at boot time?

glOrtho inverts the "z-buffer"

Jonas Hultén — Wed, 18 Sep 2002 21:49:08 -0000

When using glOrtho as opposed to glPerspective, the
polygon clipping is reversed so that polygons nearer the
eye is drawn behind polygons futher away from the eye.
The testexample Test4.zip demonstrates this.

Out of memory when loading 8k sound

Jonas Hultén — Sat, 14 Sep 2002 00:16:24 -0000

When trying to load a specific sound, the following
happens:

kernel panic: out of memory; about to run over kernel
stack
arch: aborting the system

The sound is a 44100kHz mono WAVE file. The sound
and (crashing) source is included in Test3.zip

CDRom TOC structure correction

Jonas Hultén — Fri, 06 Sep 2002 15:10:02 -0000

The cdrom TOC structure contains a 'dunno'-field. This
contains the sector number after the last track on the
CD. It should be renamed.

cdrom.h:
/* TOC structure returned by the BIOS */
typedef struct {
uint32 entry[99];
uint32 first, last;
uint32 dunno;
} CDROM_TOC;

Create/destroy texture causes crash

Jonas Hultén — Thu, 05 Sep 2002 23:57:53 -0000

Creating and destroying a 128x128 pixels texture
(loaded as tga) crashes the dreamcast the third time.
Look at the attached code.

Sound loading crashes after reinit

Anonymous — Wed, 04 Sep 2002 15:30:16 -0000

If the sound manager is started, stopped and started
again, sound loading hangs the machine. The following
code does the trick:

snd_init();
int soundIndex = snd_sfx_load("/rd/dingmono.wav");
snd_sfx_unload(soundIndex);
snd_shutdown();

snd_init();
soundIndex = snd_sfx_load("/rd/dingmono.wav");
// control never returns here.
snd_sfx_unload(soundIndex);
snd_shutdown();
