> Sl6000 Hardware Accelerated Display?, Anyone figured out how to use it?

I've been looking at the kernel source for the SL6000's framebuffer driver, and I can see an API provided to access the hardware acceleration - but it's documentation is pretty much zero sad.gif

The only example of it being actually used in the driver itself is the tc6393_clear_screen() function, that uses the hardware rectangle fill to clear the screen. There's a very interesting looking command set provided in the tc6393fb.h file, and an ioctl provided to pass lists of commands to the graphics hardware for processing - but the actual commands (although defined) aren't actually documented sad.gif

The clear screen example in the driver is
static u32 cmd[6];
cmd[0] = PXAIO_COMDI_DSADR|PXAIO_COMDD_DSADR(((int)remapped_fbuf));
cmd[1] = PXAIO_COMDI_DHPIX|PXAIO_COMDD_DHPIX(xres - 1);
cmd[2] = PXAIO_COMDI_DVPIX|PXAIO_COMDD_DVPIX(yres - 1);
cmd[3] = PXAIO_COMDI_FILL|PXAIO_COMDD_FILL(0xffff);
cmd[4] = PXAIO_COMDI_FLGO;

Using the ioctl interface to the framebuffer, this would be:
static u32 cmd[6];
cmd[0] = 5;
cmd[1] = PXAIO_COMDI_DSADR|PXAIO_COMDD_DSADR(((int)remapped_fbuf));
cmd[2] = PXAIO_COMDI_DHPIX|PXAIO_COMDD_DHPIX(xres - 1);
cmd[3] = PXAIO_COMDI_DVPIX|PXAIO_COMDD_DVPIX(yres - 1);
cmd[4] = PXAIO_COMDI_FILL|PXAIO_COMDD_FILL(0xffff);
cmd[5] = PXAIO_COMDI_FLGO;
ioctl(fbHandle,TC6393FB_ACC_CMD_WRITE,cmd);

and then I'm guessing that if you want to make sure it's completed before carrying on, you can use:
ioctl(fbHandle,TC6393FB_ACC_SYNC,0);

But the tc6393 looks like it can do blitting as well....I've no idea what the rest of the command API def's actually do though?

And glory be - Toshiba haven't released a datasheet for the chip sad.gif
When I eventually get my hands on my SL6000 (my wife's hidden it 'til Christmas) I'll start trying some of the commands, see if I can work it out through trial & error.....unless someone else beats me to it of course smile.gif

SDL would go much quicker with a bit of the ol' hardware accel...

I have found the Tosa ROM 1.12 to be extremely slow in changing between applications compared to my theoretically slow sl5500's ROM 2.38. I hope this is the right thread!

I take notes and transfer information between various apps and was amazed at how long it has always taken to switch between already apps. Does this have to do with Accelerated display? I'm talking between browser, editor, email, even before installed any ipks to the bare bones 1.12.

thanks,
sdjf
