I think this question must have been asked a million times, but is their any
way to get even 800 X 600 X 16bit support in QNX RTP running on CL-GD-5446
???
any response will be appreciated
thanks

Hi Ripunjay,
Currently there isn’t support for the Cirrus Logic video chipsets,
however in Patch A, there is a SVGA driver that will allow you to get
higher resolutions as well as more colors. However this driver is
unaccelerated.

thanks a ton Erick,
now where can i get the PATCH A that you are talking about???

It’s not yet publicly available. The feature list has been
frozen, and it’s in QA’s hands now. Those of us in the building
have learned to be… cautious in our expectations of patch
release dates.

Does this driver NOT REQUIRE VESA 2.0 spec video BIOS? If it still
needs VESA 2.0 compliance then it still won’t help all the people
wanting to run QNXRTP on older laptops. The “acceleration” on those
older chips didn’t go much beyond a few windows specific rectangle,
line and blitting functions. The smaller memory footprint and
enhanced speed of QNXRTP should more than make up for the “loss”
of any little video acceleration from a 5 year old video chip.
But to be stuck with 4bit color is, well, ewwww! Oh well, I’m off
to download the updated ISO image.

It is designed to work in ‘bank-switched’ mode so it does not need VESA
BIOS.

Indeed, it works remarkably fast on my laptop with Trident chip. The
vesa driver does not work there.

And exactly how are rectangles, lines and blitting Windows specific? We use
all of those features.
Personally, I think the farther back you go in video card land, the more
important accelleration is. Using the CPU to draw a rectangle over an AGP
bus is much much faster than trying to do so over an ISA bus. Using
accellerated hardware to draw a rectangle is almost completely independant
of the bus speed.
Good news then!

OK, OK, the functions and supporting drivers were originally optimized
for Windows. Sheesh. Of course anyone can write a driver for any OS that
calls those same acceleration functions if they have the chip specs or
the time to hack/reverse engineer them.
