One Step Closer to 3D Graphics Access...
Posted by XanTium | 15-10-2007 19:50 EST

From eurasia.nu:

The hunt for 3D graphics access from homebrew/linux ("Other OS") on the PS3 goes on and the guys over at ps2dev.org have made significant progress recently after IronPeter managed to blit the push buffer from user land using fifo control registers.

I don't know what that means exactly but this is great, full access to the graphics card running linux would be awesome. biggrin.gif

Hypervisor is using RSX under "Other OS" mode, for bltbit (i.e rectangle pixel copy from cpu side ram towards gpu side ram). GPU has been initialized properly by Hypervisor for that purpose.
Being able to insert our own bitblt commands after the one issued by HV at each frame, means that we can expect 2D rectangle hardware accelerated copy (with stretching or not) into Linux software.

fast 2D emulators, Linux driver allowing fast window moving on desktop, etc...

for 3D, it's more complex because it's possible the GPU hasn't been prepared for that by HV...

Also another big gain is the ability to store data into the 252Mb of gpu side ram and reuse it for immediate bltbit drawing (fast, this time).

We really can't say now that PS3 homebrew has only 256Mb.
We now have 506 Mb (252Mb more likely reserved for 2D sprites storage).
