Re: Problem with compiling modules
drm with XFree86-4.1.0, linux-2.4.23 for ATI Radeon Mobility
and related problem with DRI
Warsaw January 12, 2004
Problem with compilation kernel modules,
linux-drm-4.1.0-kernelsource.tar.gz
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
from, http://www.xfree86.org/~alanh/
*****************************
Setup: Laptop Clevo 4600 (vel Eurocom 4600) with
Pentium III Mobility 1.2. GHz
ATI Radeon Mobility (Integrated) AGP 4x
M6-P (indicated also as R100/7000, or LY)
32 MB VideoRAM: 64bit DDR SDRAM (i830MP)
512 MB RAM
kernel Linux-2.4.23 (from, www.kernel.org)
XFree86-4.1.0-50 (from RedHat)
Mesa-3.4.2-10 (from RedHat for RH-7.2 and use with XFree86-4.1.0)
distribution Linux RedHat-7.2 (with erratic supplements)
gcc2.96-112.7.2 (from RedHat errata for 7.2)
(examination of using gcc-3.3.2 does not remove the trouble)
I am including the compilation report (revealing also possible causes
of the trouble) below the following message.
Compilation of linux-drm-4.2.0-kernelsource.tar.gz passes without
problem (I need however the modules for XFree86-4.1.0).
I have been tempted to compile the module by message from the XFree86
DRI discussion list stating that the module version from,
http://www.xfree86.org/~alanh/
can solve the following known problem of radeon.o module compiled
from the kernel linux-2.4.23 source (generally later than 2.4.18):
An effort of launching a graphic application using DRI results in total
freezing of the keyboard, mouse, screen so that only switch off can be
done (glxinfo shows that DRI , AGP and all the rest are enabled).
Kernel and all modules have been compiled using the same version of the
compiler, gcc2.96-112.7.2 (from RedHat-7.2 Errata)
However , I have observed that
launching the graphic application using DRI with XFree86-4.1.0 under
kernel 2.4.18 (Linux kernel 2.4.18 from http://www.kernel.org)
and subsequent warm restart to 2.4.23 removes this unrequired effect
as long as the machine is switched on (subsequently, a number of WARM
restarts can be done and this will not restore the freezing effect).
I have found this has most probably nothing with APM or using
the EXT3 and occurs with XFree86 subversions 4.1.0, 4.2.0 and
apparently does not depend on the subversion number.
Assignment of RAM intervals appears to be the only difference between
logss of X starting under linux-2.4.23 booted directly after switching
the machine on and the reports of starting X under the 2.4.23 warm
restarted from 2.4.18 under which a graphic application using DRI has been
launched. Note, starting X under 2.4.18 without launching such application
will not remove the effect of freezing after the warm restart to 2.4.23.
(examples of the application: gears, tunnel, tunnel2 )
I am sending this message in hope it will appear helpful in solving
the known problem of using DRI with ATI RADEON for kernels
later than 2.4.18
(others report the problem preserves also with Linux kernel 2.6.0,

warnings do not encourage using the driver formally compiled in this way).
