Hello, Mesa3d users, Thanks for high-quality software, yesterday I've succeeded with building the latest git snap of Mesa/Gallium Cell Driver. Everything is OK with building, except two small issues: missing ";" after cell_velems_state struct definition in cell_context.h and missing libidentity.a target, that solved simply by performing make in src/gallium/driver/identity folder. With glxinfo it describes itself as OpenGL renderer string: Gallium 0.4 on Cell OpenGL version string: 1.5 Mesa 7.9-devel However, experimenting with driver on PS3 appears to be one big issue for me. First, running OpenGL apps returns "PPU: Multiple rendering contexts not yet supported on Cell.", then I was not able to connnect x11vnc server to E16 desktop session running on gallium drivers. And finally, none of progs/demos are working returning "unknown Opcode 0x00" for all 6 spus. So, what could be wrong with it, is current git main branch broken?? Does it work for you, what versions have you tested? Thanks, M. |

The Cell driver was broken a few weeks ago because of some new gallium architectural changes. I haven't had time to update the driver. I'd suggest using the Mesa "7.8" branch in the mean time. The Cell driver on that branch should be fine. -Brian |

Hello, Brian, Thanks for suggestion, Last night I've tried out 7.8 RC1 source tar ball from ftp://ftp.freedesktop.org/pub/mesa/7.8/RC/ Results are pretty same on PS3, I wonder what could be wrong with it: [root@host192-168-0-104 Mesa-7.8-rc1]# cd progs/xdemos/ [root@host192-168-0-104 xdemos]# ./glxgears SPU 2: bad opcode: 0x0 SPU 0: bad opcode: 0x0 spu_command.c:714: cmd_batch(): assertion 0 failed.
