Title: shaders and the radeoHD driver Post by: peat on January 13, 2009, 11:12:29 PM i have been working on getting openarena working with my HD2400 using the radeoHD opensource driver , using the DRI , but I have a question relating to the shaders, they are creating stalls in the pipeline,
terrain.shader and weapons.shader seem to be the problem.. when I do a 3d pipeline clean check i hang. I think these shaders are at fault.. but need info on how they were generated.. have you guys run them trough shader analyzer.. for GPR or export utilzation.... :cool: Title: Re: shaders and the radeoHD driver Post by: fromhell on January 13, 2009, 11:34:09 PM .shader files in this case has nothing to do with glsl or fragment shaders.

so how are the shaders being loaded .. When i load my shader i have to explicity tell it where it is via a DMA into the FB ( local memory ) and then through the CP tell it where it is via thre indrect buffers... my shaders are precompiled through a windows ATI (catalyst) , converted from ELF (ATI output) to something meaning ful... and then i convert these to load addresses recognised by the GPU, but yours are loaded on demand (LOD), sorry but how can you load 64 shaders (whihc i saw in the logs ) without running through an ATI compiler (for GLSL) or through an assembler (for IL)... I am using the void show_state (adapter_t *adapt) function to detect the error... btw hte mouse response is bad , but that is thel east of the problem with the R6xxx and adeonHD driver.. :) Title: Re: shaders and the radeoHD driver Post by: peat on January 14, 2009, 01:29:14 AM hey fromhell,
me thinks we are going to hav to get tech very fast coz i dont see how openarena can prcoduce textured output , on the HD2400 without a precompiled shader... loaded into FB what do think.. coz i would like to use the 8 pipelines avaiable in the new r6xx arhiteciture and coz nvidia are not doing open source its kinda difficult to prgram for those guys...

They are textures, scripted to allow effects and interacting with game events and other things, but only textures, on Rage Pro or Voodoo or Riva TNT level hardware. They are not the same as pixel/fragment shaders, are not compiled into bytecode, and are not executed in GPU hardware.

when i finally finsished up last night it occured to me that that perhaps was the case , coz i could not reconcile such great graphics with not being H/W accelerated .. but i should have noticed the frame rate which on my gaming m/c should have been higher than it was thanks for the reply.. |
