As threatened, xorg-x11-6.8.0-r1 is stable for sparc as of earlier today. |
5 |
I have mentioned before that with Creator graphics and libGL, you now get |
6 |
a sort-of working ffb_dri.so for direct rendering. |
7 |
|
8 |
Rather than rehash what is going on with it, I am forwarding a copy |
9 |
of a bug I have opened for tracking libGL+ffb status. If you are a |
10 |
Creator graphics user, you might want to review the bug, and please |
11 |
post your experiences to it. Please do not open a new bug, because that |
12 |
makes tracking much harder, and so more likely to get lost. |
13 |

Summary: libGL (DRI for Creator graphics) sometimes fails with |
30 |
xorg-x11-6.8.0-r1 |
31 |
Product: Gentoo Linux |
32 |
Version: unspecified |
33 |
Platform: Sparc |

New with xorg-x11-6.8.0-r1, the direct rendering module ffb_dri.so for use with |
46 |
libGL (mesa) and Sun Creator graphics cards actually loads and runs. |
47 |
|
48 |
However, it is incomplete at this point. This means that some applications can use it |
49 |
with no problems (and run much faster as a result), but others do not run correctly. |
50 |
(Example: glxgears runs very fast, but is black-on-black so doesn't show anything. |
51 |
The Mesa 'stars' demo runs fine and is much faster.) |
52 |
|
53 |
On sparc, it is always built, and if in your xorc.conf file, you load dri and glx, |
54 |
it is used for libGL applications. Quick check: glxinfo starts out like this: |
55 |
================ferris@terciopelo:PROJECTS/SIMULATION/ALL-IN-ONE [246]% glxinfo|more |
56 |
name of display: :0.0 |
57 |
display: :0 screen: 0 |
58 |
direct rendering: Yes |
59 |
server glx vendor string: SGI |
60 |
server glx version string: 1.2 |
61 |
server glx extensions: |
62 |
GLX_ARB_multisample, GLX_EXT_visual_info, GLX_EXT_visual_rating, |
63 |
GLX_EXT_import_context, GLX_OML_swap_method, GLX_SGI_make_current_read, |
64 |
GLX_SGIS_multisample, GLX_SGIX_fbconfig |
65 |
client glx vendor string: SGI |
66 |
client glx version string: 1.4 |
67 |
=================== |
68 |
(The key being that 'direct rendering: Yes') |
69 |
|
70 |
If your application happens to fail, you can disable direct rendering for ffb |
71 |
with the LIBGL_ALWAYS_INDIRECT environment variable; e.g., |
72 |
================================== |
73 |
fmccor@terciopelo ferris $ LIBGL_ALWAYS_INDIRECT='yes' glxinfo |
74 |
name of display: terciopelo:0.0 |
75 |
display: terciopelo:0 screen: 0 |
76 |
direct rendering: No |
77 |
================================== |
78 |
|
79 |
If you set this in your environment, libGL behaves the same way as it did with |
80 |
xorg-x11-6.7.0. |
81 |
|
82 |
This is a known problem addressing current limitations in a work in progress. |
83 |
If you run into the problem, please report it on this bug and try to show what fails for you. |
84 |
We need that information to work on making this feature more robust. |
85 |
|
86 |
(By the way, if you are kernel-2.6.7, this does not apply. You can't get at drm |
87 |
for ffb at all, and that is a kernel problem/feature.) |
