Subject: [SDL] WinCE timers, continued

Here's a strange timer for Windows CE that doesn't ignore time across
suspends.  It uses GetSystemTime to keep the time continuous, and GetTicks to
get finer-grained readings than 1 second.  It detects the difference between
the GetTicks time and GetSystemTime time on power-on to keep the error within
one second max.

It's not a patch on the current win32 timer code -- took one look at that and
figured it had more than enough #ifdefs already.  It's windows-ce specific.

Another thing I've noticed is that the Windows CE 4.0 and newer API has
functions warn processes about suspends.  This is something SDL REALLY needs
for audio in particular, because turning it off while it's playing causes
anything that uses audio to hardlock the system on power-on.  Unfortunately I
don't have 4.0 to play with.  :(

Subject: [PATCH]SDL mprotect() crash fix

(I'm going to throw this patch your way at the suggestion of #SDL --
for some reason, I had some difficulty sending it to the main list
last time, and I go bonkers subscribing to send each email or
patch...)

Currently, when I run SDL applications as non-root using
SDL_VIDEODRIVER=dga, the fbdev fallback mprotect()s read/write the
proper size of mmapped /dev/fb0 (7.5MB), but on framebuffer release
mprotect()s read-only the range by the entire size of my video memory
(128MB), which causes a segfault:

#0  0x002a9a27 in ?? () from /lib/libc.so.6
#1  0x04a63eb6 in SDL_XDGAUnmapFramebuffer (screen=3D0) at XF86DGA2.c:978
#2  0x04a63efc in SDL_XDGACloseFramebuffer (dpy=3D0x9d3f008, screen=3D0)
    at XF86DGA2.c:268
#3  0x04a68b57 in DGA_Available () at SDL_dgavideo.c:98
#4  0x04a53677 in SDL_VideoInit (driver_name=3D0xbfb0bfc7 "dga", flags=3D0)
    at SDL_video.c:180
#5  0x04a2613f in SDL_InitSubSystem (flags=3D32) at SDL.c:74
#6  0x04a2617c in SDL_Init (flags=3D32) at SDL.c:166
#7  0x08049722 in main (argc=3D1, argv=3D0x0) at testwin.c:32

This is SDL 1.2.8 on Fedora Core 4, radeon driver for a Radeon 9250,
xorg-x11-6.8.2-37.

I've attached a one-line patch against SDL CVS that updates the size
of the framebuffer at framebuffer map time so that the mprotect() on
unmap will be the same size.  I'm not sure if this is the best
approach (i.e. one might want to retain the original value), but it
does make my SDL applications work without segfaulting.

-- Best of luck, Mark Schreiber

Subject: SDL_numjoysticks: multiply defined

The following linker error is produced when I try to build SDL CVS on Tru64.
ld:
.libs/libSDL.lax/libjoystick.a/SDL_sysjoystick.o: SDL_numjoysticks:
multiply defined

SDL_numjoysticks is defined in both src/joystick/SDL_joystick.c:48: and
SDL12/src/joystick/dummy/SDL_sysjoystick.c:37:.
As a result, compilation produce "multiply defined" errors, when link.

Subject: [PATCH] build SDL with nonexecutable stack


libSDL is by default marked with an executable stack, which it doesn't
actually need. the reason for this is that there are assembler files in the
source tree not properly annotated with the "noexec stack" section. As such
the linker does a safe-fallback and marks the whole lib as "requires
executable stack".

the patch below removes this by adding annotations. As far as I can see it
shouldn't break anything.

Subject: [SDL] SDL_SoftStretch() fixed!

Ok, after debugging the night I found the error:

in video/SDL_stretch.c in Line 81

    /* See if we need to regenerate the copy buffer */
    if ( (src_w == last.src_w) &&
         (dst_w == last.src_w) && (bpp == last.bpp) ) {
        return(0);
    }

the second comparison should be (dst_w == last dst_w).
Perhaps someone could apply it to the source...

Regards,
  Thomas Omilian

Subject: [SDL] [RFC] get_ticks broken on linux

It uses gettimeofday to calculate the timedifference.
Gettimeofday returns current time which is seldom monotonous.
This breaks SDL timer subsystem. (time callbacks and all that
get borked when the time difference ms is suddenly ~ 2^32)

I posted a message about this earlier but got no response.
Some thoughts on this matter would be appreciated.
(Or even an explanation for the lack of interest.)

A patch below would use the posix timers that have been around
since posix 93 and do provide a good source of monotonous time
on linux boxes (and on few others too).

The following patch is also availabe at:
http://www.hut.fi/u/tkyntola/SDL-1.2.9-clockfix.patch

It's against 1.2.9, but I can easily rediffit against
the cvs branch is needed.

cheers,

Subject: [SDL] [PATCH] Use nanosleep on OS X

Hi,

The current version of SDL_Delay on OS X seems to always sleep at least 10
msec. OS X has nanosleep(), which performs shorter sleeps well. The
attached patch makes it use that one instead of select() as currently.

Subject: [SDL] [PATCH] Switching between fullscreen/windowed on OS X

Hi,

When switching from fullscreen to windowed mode for opengl applications,
the current version of SDL sets an harmless error, regarding usage of a
NULL semaphore. This is due to code which tries to shut down a blitting
thread, which is only started for double buffered 2d video modes, not for
opengl. The attached patch fixes this.
