Subject: [BUG] E7x05 chipset bug in 2.5 kernels' AGPGART driver.
Date: Wed, 2 Apr 2003 20:50:03 +0200 [thread overview]
Message-ID: <200304022050.03026.fendrakyn@europaguild.com> (raw)
Hello,
I noticed there is a bug in E7x05 (Granite Bay) chipset support of the AGPGART
driver that does not seem to have been submitted yet.
There is a mistake in the Makefile of drivers/char/agp, the line concerning
i7x05-agp support does not match the one in the Kconfig, thus e7x05 support
is never compiled, be it as a module or in the kernel.
There are mistakes in the i7x05-agp source code. A few missings ";" and some
undeclared functions prevent the module from properly compiling. Those
mistakes are easily fixed though.
The last problem is more important and I have yet to find a solution. It seems
like the driver stores device 0 in his agp_bridge->dev (0x255d for E7205,
0x2550 for E7505) but it uses registers from device 1 (0x2552) thus the
chipset cannot be configured properly. The fetch_size function fails to
determine aperture size.
Sorry if this is redundant and is already being looked at.
Gareth C.
P.S : include answers in C.C if you may, pretty please.
