Introduction

  • FreeBSD character device which gives you direct access to PS3 GPU from user-space.

Features

  • Upto 3 GPU contexts simultaneously.
  • Direct control of GPU FIFO from user-space.
  • Support for hardware cursors.
  • Mapping of GART memory into GPU address space is done by the driver. That means user-space applications do not have to worry about it.
  • Heap management for GART and VRAM memory.
  • Support for display buffers.

Kernel Driver

Building

  • You can cross-compile the kernel module or build it natively on PS3 FreeBSD.
  • The kernel module and the kernel should mactch. That means the kernel module should be build against the same kernel source else the kernel module cannot be loaded (The same applies on Linux).
cd /usr/devel
env MAKEOBJDIRPREFIX=/usr/obj/PS3 make TARGET=powerpc TARGET_ARCH=powerpc64 buildenv
cd /home/glevand/ps3gpu
make
ls -l ps3gpu.ko

Test

  • ps3gpu_test is a user-space application for testing ps3gpu kernel driver.
cd ps3gpu_test
make
