OpenGL upgrade (recompile mesa) on 14.1


Hi, I need to use OpenGL (>=3.2) which is provided by mesa (>=10.0). Current mesalib in 14.1 is 9.1. Can someone provide a list of package that I need to re-compile one after another? Thanks!

More general, I may also want to try Intel's new graphic driver. What's the list in that case?

Thanks a lot!

you may need to upgrade libdrm, xf86-video-intel, mesalib, mesa demos/tools?. Are you sure that your display card supports OpenGL 3.2?

Thanks for your input. I'm using a Intel HD 4400 and it supports OpenGL 4.0.

I have re-compiled mesa and libdrm. But when glxinfo still gives me:

Quote:
OpenGL version string: 3.0 Mesa 10.0.1
and the application still tells me your OpenGL version is 3.0 and we want at least 3.2. Any ideas?

The list is here

https://01.org/linuxgraphics/downloa...-stack-release

It does make a huge difference from the kernel i915 or i965 driver but man is it a lot of hair-pulling work. It is even difficult on the ones that Intel has made installers for since they aren't quite up to Intel's version requirements even on the lastest releases (I tried OpenSuse 12.3 and StudioUbuntu 13.10)

The kernel drivers gave me 3FPS on Ungine Heaven testbed. Intels drivers gave me 40FPS. My new nVidia card gives me 107 FPS at higher settings and with a LOT less work.

Mesa3D currently only carries the OpenGL 3.3 specification with MesaLib 10.0.1.

The only video cards that possibly have the OpenGL 4.x specification drivers are AMD's FGLRX driver and Nvidia's GLX driver, both proprietary drivers. Intel's OpenGL drivers are based on the open-source drivers.

Yes, it's very tedious...I hope Pat can upgrade them soon in -current. I may give a try on the whole stack listed in the link.

But do I need to re-compile other packages that depend on these driver package? e.x., mplayer?

Yes, why cannot Intel provide open-source drivers that can be used easily? I used Nvidia's proprietary drivers before and I found they were easy to use.

Intel contracted Tungsten Graphics, which developed open source drivers for the DRI, to write their open source xorg drivers. Since the open source implementation of OpenGL is MesaLib, it can only support the available API from the library provided. Nvidia and AMD utilize a different OpenGL implementation more closely based on the proprietary and licensed SGI OpenGL implementation which is why their drivers will provide advanced support factors which MesaLib has to have said code contributed back to it to gain said support.

From what I read, Intel is devoting considerable effort to creating a solid and easy to implement set of linux drivers. They are just very new to the game. I consider them to be very close to ATi who was new to the game years ago. nVidia is still the king but they have earned it by being the alternative "go to guy" basically forever and for everybody. They even made OS/2 and BeOS accelerated drivers. I've been using their Linux drivers for over 10 years, and rarely even been moderately disappointed.

The only current problem with nVidia is with certain older units and certain kernels and the available patches are "sketchy". Example: I have a perfectly good FX-5200 which is more than adequate for desktop and light gaming but it is nearly useless at this time to try to get it to operate properly with the legacy drivers and gcc 4x, or with a version 3x kernel. Serious Catch 22 but then the FX5200 is over 10 years old... ancient in PC years.
