ATI zieht nach: Linuxtreiber für Radeon 8500(LE)

Linuxtreiber fand man bisher nur bei nVidia, doch langsam bieten auch andere Hersteller entsprechende Treiber an. Für die Profi-Karten FireGL 8700 und 8800 gab es schon länger Treiber für Linux, nun stellt ATI sie auch für die Radeon 8500(LE) bereit. Der Treiber ist noch Not Supported.

This driver is based on the xfree86 version mentioned in the document header.
(see http://www.xfree86.org/4.0/ for documentation)
You must install this version of xfree86 before installing the drivers for
the ATI Radeon 8500.

If your Linux distribution does not provide the XFree86 version that is
supported by the current driver version, you must download and install
the respective xfree86 binaries from
'ftp://ftp.xfree86.org/pub/XFree86/4.1.0/binaries/'
or from
'ftp://ftp.xfree86.org/pub/XFree86/4.2.0/binaries/'.
The current drivers for X4.1.0 and X4.2.0 may be compatible with XFree86
from revision X4.0.2 trough X4.2.0.
However, we do not explicitely verify this.

AMD Athlon XP, AMD AThlon 4, AMD Athlon MP and Model 6 Duron

Some Linux kernels have a conflicting cache attribute bug
that is exposed by advanced speculative caching in newer AMD
Athlon family processors (AMD Athlon XP, AMD Athlon 4, AMD
Athlon MP, and Models 6 and above AMD Duron). This kernel
bug usually shows up under heavy use of accelerated 3D graphics
with an AGP Graphics card.

Linux distributions based on kernel 2.4.19 and later
*should* incorporate the bug fix. But, older kernels
require help from the user in ensuring that a small portion
of advanced speculative caching is disabled (normally done
through a kernel patch) and a boot option is specified in
order to apply the whole fix.

ATI's driver automatically disables the small portion of
advanced speculative caching for the affected AMD processors
without the need to patch the kernel; it can be used even on
kernels which do already incorporate the kernel bug fix.
Additionally, for older kernels the user performs the boot
option portion of the fix by explicitly disabling 4MB
pages. This can be done from the boot command line by
specifying:

mem=nopentium

Or by adding the following line to etc/lilo.conf:

append = "mem=nopentium"
