* You have to patch your LV1 and enable 4KB GPU IO page size support else ps3gpu won't work.

* You can either patch your LV1 permanently (e.g. with my ps3mfw task for LV1) or do it at run-time with my '''gpu_4kb_iopage.sh''' script.
* You can either patch your LV1 permanently (e.g. with my ps3mfw task for LV1) or do it at run-time with my '''gpu_4kb_iopage.sh''' script.
* By default, LV1 supports 1MB and 64KB GPU IO page sizes but we need 4KB page size. The reason for this is that it's very hard to allocate 1MB or 64KB continuous memory chunk in FreeBSD kernel (same applies for Linux).
* By default, LV1 supports 1MB and 64KB GPU IO page sizes but we need 4KB page size.
* gpu_4kb_iopage.sh should work with my petitboot and my Linux kernels and even on FreeBSD if you load ps3physmem driver before using the script.

* The application demonstrates how to allocate GART and VRAM memory, how to load, set and move cursor and how to flip.
* It shows you how to use RSX FIFO and send commands.
* It shows you how to use RSX DMA engine for memory copying (used e.g. in X11 driver all the time).
* It shows how to load vertex and fragment programs, draw vertices and flip displlay buffers.
* It shows how to use textures.

==Tiling==
* We have to use a different video pitch.
* Use e.g. ps3dm VUART driver and ps3vuart-tools to set video pitch allowed for tiling.

* The square in the middle of the screen is the source.
* The square on the left was copied from the source by RSX DMA using positive pitches, from top to bottom.
* The square on the right was copied from the source by RSX DMA using negative pitches, from bottom to top.
* Unfortunately it's not possible to make a screenshot of hardware cursor by dumping video ram content because hardware cursor is overlayed.

* You need this driver to run X11 server on PS3.
* You need this driver to run X11 server on PS3.
* The driver supports hardware acceleration through X11 EXA interface.
* Currently the driver uses only RSX DMA engine to copy memory.

* The driver is still work in progress but is usable. Expect to see some artefacts :)
