From: "Mike Gorchak"
Subject: New QNX patches

Please apply patch qnx4.diff, which is attached. What has been done:
1)Added back OpenGL ES renderer for QNX target. Added few corrections to
OpenGL ES renderer to let it work under QNX. OpenGL ES renderer do not
support textures under QNX, so I think some additional work must be done.
2) Added GL_OES_query_matrix extension to SDL_opengles.h header file, which
required by OpenGL ES 1.1 specification.
3) Added attribute clearing at the entrance of function
SDL_GL_GetAttribure(). Added error checking into the function
SDL_GL_GetAttribure(), because some attributes can't be obtained in OpenGL
ES 1.0.
4) Porting testdyngles to OpenGL ES 1.0 (1.1 has glColor4ub() and
glColor4f() functions, but 1.0 has glColor4f() only).
5) Added error checking after obtaining attributes using
SDL_GL_GetAttribute() function to the testgl2 and testgles.
6) Small correction to testmultiaudio with printing errors.
7) Added software and accelerated OpenGL ES 1.0 support into the QNX GF
driver.

Please remove ./src/audio/nto directory - it will not be used anymore.
Please create ./src/audio/qsa directory and add content of the archive
qsa.tar.gz into this directory. I rewrote some sound code, added support for
multiple audio cards, enumeration, etc. Added initial support for capture.

As far as I can understand SDL 1.3 is not supporting audio capture right now
? Sam, Am I right ? Or audio capture must be supported through the
PlayDevice routine ?

And last, please put file SDL_gf_opengles.c to  the ./src/video/qnxgf
directory. It is OpenGL ES 1.1 emulation layer for some functions, which are
not supported by OpenGL ES 1.0.

QNX Photon and GF drivers are under construction. Please be patient. QNX Photon and GF drivers are being constructed.
QNX QSA (QNX Sound Architecture) driver is ready.
QNX CDROM driver is ready.
QNX HID input driver is being constructed.
----------------------
-- SDL QSA driver --
----------------------
Due to QNX Sound Architecture limitations software could not determine
what playback channels are designed for, so some casus can be. For example,
output after testmultiaudio test utility execution:
Using audio driver: qsa
playing on device #0: ('Vortex 8820 @ fb000000 d0')...done.
playing on device #1: ('Vortex 8820 @ fb000000 d1')...done.
playing on device #2: ('i8x0 @ d800 d0')...done.
playing on device #3: ('i8x0 @ d800 d1')...done.
playing on all devices...
Open device 3 failed: QSA: snd_pcm_channel_params failed: Invalid argument
If speakers are connected to both audio cards: Vortex 8820 and Intel
Integrated Audio we can hear sound playback on device #0 and devices #2, #3
only. Device #1 is an unknown PCM channel which does not produce any sound.
As for error during device #3 opening, it's caused by QSA software mixer
channel, because it can't open real hardware device #2, since it's already
opened by SDL.
After simultaneous sound playback on all devices utility testmultiaudio
stays running waiting for sound playback finish on device #1, which is
locked up due to some Aureal Vortex 8820 driver limitations.

b) As confirmed by QSSL none of existing video drivers has support of
doublescan low-resolution video modes. So modes below 640x480 are not
supported. If your video driver supports low-resolution video modes, please
add SDL_GF_LOWRESOLUTION flag to the gf_devicename array in the SDL_qnxgf.c
source file.
