Hello everybody,


i start a new thread regarding one of my issue:


what i want to do is to to enable directGMA on my firepro; so that i would be able to use it with FPGA board card after. For that, i runned the following command (on suse 13.1) after my installation of the amd driver from AMD website :

aticonfig --initial --adapter=all -f

aticonfig --set-pcs-val=MCIL,DMAOGLExtensionApertureMB,96

aticonfig --set-pcs-u32=KERNEL,InitialPhysicalUswcUsageSize,96


i verified so that the pcs were correctly entered :

aticonfig --get-pcs-key=MCIL,DMAOGLExtensionApertureMB

     Value in hex (decimal): 0x00000060 (96)

aticonfig --get-pcs-key=KERNEL,InitialPhysicalUswcUsageSize

     Value in hex (decimal): 0x00000060 (96)


and then i reboot. After reboot nevertheless, i don't have extension GL_AMD_bus_addressable_memory when i run glxinfo; and when i try to get the pcs value that i initialized before reboot, here are the results :

aticonfig --get-pcs-key=KERNEL,InitialPhysicalUswcUsageSize

     Error: Key KERNEL,InitialPhysicalUswcUsageSize not found in PCS database

aticonfig --get-pcs-key=MCIL,DMAOGLExtensionApertureMB

     Error: Key MCIL,DMAOGLExtensionApertureMB not found in PCS database


here are the results of several command:
