/*
|
|
||||||
|
|
||||||
/dev/3dfx device for 2.x kernels with MTRR settings enabled.
|
|
||||||
|
|
||||||
Compile with :
|
|
||||||
|
|
||||||
gcc -O2 -DMODULE -D__KERNEL__ -I/usr/src/linux/include -pipe
|
|
||||||
-fno-strength-reduce -malign-loops=2 -malign-jumps=2
|
|
||||||
-malign-functions=2 -c -o 3dfx.o 3dfx_driver.c
|
|
||||||
|
|
||||||
Add -D__SMP__ if you're running of an multi-processor system.
|
|
||||||
Add -DHAVE_MTRR if you have and want MTRR settings.
|
|
||||||
Add -g -Wall -Wstrict-prototypes -DDEBUG, if you are debugging.
|
|
||||||
|
|
||||||
Original by Daryll Straus.
|
|
||||||
Port to 2.1 kernel by Jon Taylor.
|
|
||||||
setmtrr_3dfx() added by Jens Axboe.
|
|
||||||
Combining 2.0 and 2.1/2.2 kernels into one rpm,
|
|
||||||
resetmtrr_3df(), and using correct pci calls for
|
|
||||||
2.1/2.2 kernels by Carlo Wood.

ChangeLog
|
|
||||||
|
|
||||||
2000/02/04 Joseph Kain <joseph@3dfx.com>
|
|
||||||
|
|
||||||
* Updated Carlo Woord's email address.
|
|
||||||
|
|
||||||
1999/12/22 Joseph Kain <joseph@3dfx.com>
|
|
||||||
|
|
||||||
* Support for new VMA structure in Kernels 2.3.14 and higher.
|
|
||||||
This patch is based on Dieter Nuetzel's work.
|
|
||||||
|
|
||||||
1999/11/09 Joseph Kain <joseph@3dfx.com>
|
|
||||||
|
|
||||||
* Made cards static to remove conflict with hisax ISDN driver.
|
|
||||||
|
|
||||||
1998/10/30 Carlo Wood <carlo@alinoe.com>
|
|
||||||
|
|
||||||
* Re-included module versions (this source was based on the
|
|
||||||
source by Jon Taylor which was based on an older version
|
|
||||||
by Daryll Straus. I now included the later changes made
|
|
||||||
by Daryll in this source too).
|
|
||||||
* Use pci_find_device for 2.1/2.2 kernels instead of the old
|
|
||||||
pcibios_find_device. Idem pci_present().
|
|
||||||
|
|
||||||
1998/10/21 Carlo Wood <carlo@alinoe.com>
|
|
||||||
|
|
||||||
* Fixed compile bugs related to 2.0 kernels.
|
|
||||||
|
|
||||||
1998/10/21 Carlo Wood <carlo@alinoe.com>
|
|
||||||
|
|
||||||
* `struct file_operations' was changed as of kernel 2.1.118,
|
|
||||||
fixed this module to also work with versions > 2.1.117.
|
|
||||||
|
|
||||||
* Machines that don't have mtrr still need <asm/uaccess.h>.
|
|
||||||
|
|
||||||
1998/10/20 Carlo Wood <carlo@alinoe.com>
|
|
||||||
|
|
||||||
* Finally fixed in init_module() the right way. This time I tested
|
|
||||||
it too (it now really works).
|
|
||||||
|
|
||||||
* Added resetmtrr_3dfx() to clean up the MTRR settings when the
|
|
||||||
module is unloaded. This is not really necessary but its clean.
|
|
||||||
It allows to compare using this device WITH MTRR with another
|
|
||||||
method WITHOUT MTRR, without being confused by sticky MTRR settings
|
|
||||||
for instance.
|
|
||||||
|
|
||||||
1998/10/18 Carlo Wood <carlo@alinoe.com>
|
|
||||||
|
|
||||||
* Forgot the '== -EBUSY' in init_module(), causing the registration of
|
|
||||||
character device to always fail. You need to reboot if you tried
|
|
||||||
the previous version (if there is junk in `cat /proc/devices' major 107).
|
|
||||||
|
|
||||||
1998/10/18 Carlo Wood <carlo@alinoe.com>
|
|
||||||
|
|
||||||
* struct file_operations fops_3dfx was initialized wrong:
|
|
||||||
`release_3dfx' was put on the place of `fsync', causing weird
|
|
||||||
behaviour :).
|
|
||||||
|
|
||||||
* Several warning fixes.
|
|
||||||
|
|
||||||
* setmtrr_3dfx did not always return a value, and the value was
|
|
||||||
ignored, effectively ignoring errors returned by mtrr_add().
