Mesa 12.x?

[pq5190362]

Hi,

any chance you could update the Xorg-7.7-3d.tcz extension in the x86 and x86_64 repos with Mesa 12.x:

http://www.mesa3d.org/

?

Regards

[Juanito]

Hmm - that's not a small task - it might have to wait for tc-8.x...

[Juanito]

Updated in the X86_64 repo - x86 to follow.

Take care to update all X related extensions at the same time

[Juanito]

updated in the x86 repo

[Misalf]

Will the  xf86-video*  extensions need a rebuild as well or do I need to reconfigure something?

Before the update, none of the 3D applications I tried ran properly. Graphical artifacts or displaying just black.
Now 3D works but it's extremely slow compared to TC-6.x.

I'm using:
Xorg-7.7-3d.tcz
xf86-video-intel.tcz

TC-7.x x86

This means that software acceleration is being used.

You mentioned that you got a black screen previously, which would seem to indicate that hardware acceleration doesn't work with either the old or the new version for you?

[Juanito]

Do you get this when the kms driver loads:

Try to find the cause for that "driver pointer missing", maybe "strace glxgears" or Xorg.0.log shows something.

edit: Also try LIBGL_DEBUG=verbose glxgears

Yes. Neither the old nor the new version works.

Do you get this when the kms driver loads:

Haven't seen that so far. Where would it be displayed? While booting using  loglevel=  bootcode?

This line is the culprit. The i915 driver requires -march=i586 minimum.

[Juanito]

OK - I'll look tomorrow - do we want to use i686 for this as a minimum?

[curaga]

I'm not sure if there's 3d users on old cpus really, and the performance improves a lot with newer targets. Something like -march=pentium-m just for mesa might be ok. Maybe ask here if there's users on older ones and wait a week?

Will the  xf86-video*  extensions need a rebuild as well or do I need to reconfigure something?

Really couldn't hurt to update the DDX drivers.

Especially xf86-video-intel. xf86-video-intel is in constant development, but the Tiny Core Linux repos only have an old snapshot from 2015.

So, it couldn't hurt to update the Tiny Core Linux repos with a fresh snapshot of xf86-video-intel, directly from git.

By the way:

In recent events, Debian and Ubuntu more or less have deprecated xf86-video-intel in favour of xf86-video-modesetting, for more details see:

https://tjaalton.wordpress.com/2016/07/23/intel-graphics-gen4-and-newer-now-defaults-to-modesetting-driver-on-x/

https://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/intel-linux/886898-ubuntu-debian-abandon-intel-x-org-driver-for-most-hardware-moves-to-modesetting-ddx

https://www.reddit.com/r/archlinux/comments/4cojj9/it_is_probably_time_to_ditch_xf86videointel/

xf86-video-modesetting no longer is a separate package. xf86-video-modesetting is built into xorg-server since xorg-server 1.17.0.

To get the latest version of xf86-video-modesetting, it would be necessary to update xorg-server to the latest version, which is 1.18.4 at the time of writing this:
