enabling directgma feature problem, can't get extension

Jump to solution

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:

fglrxinfo

display: :0  screen: 0

OpenGL vendor string: Advanced Micro Devices, Inc.

OpenGL renderer string: HAWAII XTGL (67A0)

OpenGL version string: 4.4.13084 Compatibility Profile Context FireGL 14.301.1019

and the xorg.conf :

    SubSection "Display"

    EndSubSection

EndSection

Any idea from where is the problem?

Hi,

to me this looks like a bug. Can you please let me know which Linux distribution you are using? Can you confirm you are running a 64 Bit version. We will try to reproduce and fix it.

In the meantime can you try the following to enable DGMA:

1: Switch to runleven 3: init 3

2: Enabel DGMA:

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

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

3: Unload driver: rmmod fglrx.ko

4: Start X: init 5

Now try if the extension is exposed and DGMA was enabled. if it is working you can use it as workaround until we find out why the settings get deleted at boot.

Hello Chris,

Following your instructions, i indeed get the extensions available when running clinfo and glxinfo. I now need to make the code works .

here are the results you may want to find out the bug :

uname -a

Linux ipecamera2 3.11.10-29-desktop #1 SMP PREEMPT Thu Mar 5 16:24:00 UTC 2015 (338c513) x86_64 x86_64 x86_64 GNU/Linux

cat /proc/version

Linux version 3.11.10-29-desktop (geeko@buildhost) (gcc version 4.8.1 20130909 [gcc-4_8-branch revision 202388] (SUSE Linux) ) #1 SMP

to be honest, i wonder if this is not coming by the fact i get this ASPEED graphic card, which is some sort of integrated motherboard graphic card. If you want more, just ask me out of the forum, i think it will be easier.

however, thanks for your prompt answer.
