 |

Hello people
I have Direct Rendering working on my install but I recently noticed this in syslog:
| Code: | Jun 26 23:55:07 TsunaXbook kernel: allocation failed: out of vmalloc space - use vmalloc=<size> to increase size.
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] Maximum main memory to use for locked dma buffers: 929 MBytes.
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] Internal AGP support requested, but kernel AGP support active.
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] Have to use kernel AGP support to avoid conflicts.
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] AGP detected, AgpState = 0x1f000217 (hardware caps of chipset)
Jun 26 23:55:07 TsunaXbook kernel: agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.

Jun 26 23:55:07 TsunaXbook kernel: [fglrx] AGP enabled, AgpCommand = 0x1f000314 (selected caps)
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] free AGP = 54800384
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] max AGP = 54800384
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] free LFB = 114274304
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] max LFB = 114274304
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] free Inv = 0
Jun 26 23:55:07 TsunaXbook kernel: [fglrx] max Inv = 0

Jun 26 23:55:07 TsunaXbook kernel: [fglrx] total AGP = 16384

My 3D perf are poor and I think this might be the reason...
from what I understood, loading intel-agp and fglrx from /etc/modules.autoload.d/kernel-2.6 does load AGPGART automatically (since it's required as a dependency or something) and this prevents fglrx to load its own internal AGPGART module
You could say "ok right, why did you compile the kernel's internal AGPGART module then?"
Well simply because you have to compile it if you want to be able to also compile intel-agp which is absolutely required to access the AGP port...
So the question is: how can I tell my system to use fglrx's internal AGPGART module?
By the way, while searching on this forum, I found someone suggesting to add
| Code: | | Option "KernelModuleParm" "agplock=0" |
in /etc/X11/xorg.conf, I tried and it doesn't change anything...
Any constructive suggestion/advice/solution would be appreciated
Thanks

Not to use the internal apgart set | Code: | | Option "UseInternalAGPGART" "no" |

compile both (config_agpgart, config_agp_intel) as modules, then set
| Code: | | Option "UseInternalAGPGART" "yes" |
in your xorg.conf

I do have Option "UseInternalAGPGART" "yes" in xorg.conf and I want to use the internal AGPGART module
maybe shall I just remove fglrx and intel-agp from /etc/modules.autoload.d/kernel-2.6 and let Xorg load the modules by itself, maybe is it using some special way to load the modules with fglrx's internal agpgart module or something... this is weird anyway

AFAIK, if kernel's agpgart is loaded before the fglrx driver, fglrx can not use its own module, so you have to prevent loading the kernel module if you want to use ATI's built-in driver.

Try only listing fglrx in your modules.autoload (remove intel-agp).

help please
if I don't load anything about agp/dri in modules.autoload.d, I don't have DRI at all because fglrx doesn't load intel-agp (fglrx is loaded by Xorg since it's not in modules.autoload.d) so it can't access the AGP bridge fully and yeah this leads to NO DRI at all.
So I tried with
fglrx
intel-agp
agpgart
in modules.autoload.d, and it doesn't use INTERNAL AGPGART
I tried with
fglrx
intel-agp
same thing
with fglrx alone or with nothing, I don't have any DRI at all
any suggestion?
