Description John moser 2004-03-30 09:15:34 UTC
using dlloader, I get consistent frustrations such as the one in 
bug #377 and now this new one. 
http://bugs.xfree.org/show_bug.cgi?id=1120 on xfree's bugzilla 
shows what some people are doing to get dlloader to work. 
Loading dependencies by hand, fun. 
This time around: 
radeon_drv.so wants gRADEONEntityIndex in ati_drv.so 
ati_drv.so wants ATIPreInit in atimisc_drv.so 
atimisc_drv.so wants ATIMemoryTypeNames_88800CX in ati_drv.so 
Read back those last two.  Either everything that ati and 
radeon need should go in atimisc, or atimisc and ati should 
be collapsed into ati (since ati_drv.so is actually used as 
a driver). 
http://bugs.gentoo.org/show_bug.cgi?id=43177 on the Gentoo 
Bugzilla shows just why I don't use the elfloader. 
This. . . . is annoying.
Comment 1 Egbert Eich 2004-05-27 23:21:35 UTC
Currently the elf loader is not supported for loading driver modules.
I assume that the problem with the circular dependecies can get resolved
by using lazy bindings and only resolve symbols when used.
Anyway, this will be dealt with when support for shared driver objects is added.
Currently this is not considered a bug as the feature that would require action is 
not in yet.
Comment 2 solar[@]gentoo.org 2004-05-28 01:45:56 UTC

I think you mean the 'dlloader' is not supported. I wish this silly poorly 
designed 'elfloader' was not supported.  Anyway this could be fully
supported if you wanted to as we Gentoo & the PaX Teams have tracked
down and sometimes patched every single problem with the existing
codebase when trying to do use dlloader.

Free free to contact myself or the PaX Team if you need help in fixing 
the existing codebase.

Note 1: lazy bindings are for code not data.
Note 2: I think this bug should be reopened.
Comment 3 Adam Jackson 2004-06-25 23:05:34 UTC
reopening, this is valid.
Comment 4 Adam Jackson 2004-06-25 23:06:43 UTC
this is fixed in debrix; i'm taking it to remind myself to merge the fixes back
to xorg.
Comment 5 Adam Jackson 2004-07-21 22:49:21 UTC
fix assignment.
Comment 6 Adam Jackson 2004-08-04 17:43:31 UTC
closing.  mostly fixed in CVS, except for one or two issues i'll hit tonight.
