HOWTO: enable 3d acceleration w/ Rage Mobility (mach64)

[ellobo]

turned out that I needed to download extra dev packages (randr, render and video) before it would go past step 5. I have completed all the steps but I still do not have DRI, according to GLXinfo.

I had to autogenerate ja make install those randr, render and video. After that rest went smoothly to the end. But glxinfo states still Direct Rendering NO. xorg.conf has 16-bit color and everything should be ok, but something is still wrong I guess.

Make sure you ran the last command in step 2 while in /tmp/working/ to ensure you have downloaded mesa.

Hope this helps!

hello all
Thanks for the tuto but:....

After have adding
sudo apt-get install x11proto-render-dev
sudo apt-get install x11proto-video-dev
sudo apt-get install x11proto-randr-dev

and modified tmp/working/mesa/configs/linux-dri (to be 'DRI_DIRS = mach64')
and modified /tmp/working/drm/linux-core/drm_compat.c (comment out the function "vm_insert_pfn" )=> /*static int vm_insert_pfn

and do before step 4

cd /tmp/working/drm
./autogen.sh
./configure --prefix=/tmp/build-dir
make install
cd /tmp/build-dir/lib/
sudo cp -P libdrm* /usr/lib/ (must be su to copy)


seems that all is ok but at step 10
pop@pop-laptop:/tmp/working/drm/linux-core$ sudo cp -P /tmp/build-dir/lib/mesalibs/* /usr/lib/dri/

cp: ne peut évaluer `/tmp/build-dir/lib/mesalibs/*': Aucun fichier ou répertoire de ce type

(There is no directory /tmp/build-dir/lib/mesalibs/)

pop@pop-laptop:/tmp/working/drm/linux-core$ sudo cp /tmp/build-dir/drm/* /lib/modules/$KERNEL/kernel/drivers/char/drm/
cp: la cible `/lib/modules//kernel/drivers/char/drm/' n'est pas un répertoire: Aucun fichier ou répertoire de ce type

(and no directory /lib/modules//kernel/drivers/char/drm/)

pop@pop-laptop:/tmp/working/drm/linux-core$ sudo cp /tmp/build-dir/drm/* /lib/modules/$KERNEL/kernel/drivers/char/drm/


And then after reboot

pop@pop-laptop:~$ glxinfo | grep "direct rendering"Mach64 DRI driver expected DRM version 1.0.x but got version 2.0.0
libGL warning: 3D driver returned no fbconfigs.
libGL error: InitDriver failed
libGL error: reverting to (slow) indirect rendering
direct rendering: No

Don't know where i miss something?


Any help??

Oops, you spotted another typo in my list of steps... The directory is /tmp/build-dir/mesalibs, not /tmp/build-dir/lib/mesalibs.

My apologies!

hello
so... no luck i have to re-install fresh version from CD feisty (7.04) and then... it seems to work

pop@pop:~$ glxinfo | grep "direct"
direct rendering: Yes

But it seems to be very slow for direct rending...

So i thing to go back to edgy util another way to enable direct rending

Thank you for all

How do comment out the vm_insert line? I tried /* lllllllllll */ but that didn't work.

unlock:
spin_unlock(&mm->page_table_lock);
return ret;
}

static int vm_insert_pfn(struct vm_area_struct *vma, unsigned long addr,
unsigned long pfn)

{
int ret;
if (!drm_pte_is_clear(vma, addr))
return -EBUSY;


Thank you.

Hello
For i've done this:
/*static int vm_insert_pfn(struct vm_area_struct *vma, unsigned long addr,
unsigned long pfn)
{
int ret;
if (!drm_pte_is_clear(vma, addr))
return -EBUSY;

ret = io_remap_pfn_range(vma, addr, pfn, PAGE_SIZE, vma->vm_page_prot);
return ret;
}*/

And it works
Bye

Thank you. Everything went fine after tht 8 step however I still don't have rendering enabled.

Thank you. Everything went fine after tht 8 step however I still don't have rendering enabled.

So ... What's the message?
don't forget to replace $KERNEL by the value on uname -r and do before step 4

cd /tmp/working/drm
./autogen.sh
./configure --prefix=/tmp/build-dir
make install
cd /tmp/build-dir/lib/
sudo cp -P libdrm* /usr/lib/ (must be su to copy)

Bye
