[MPlayer-users] mga_vid and kernel 2.5

[Bartek Jakubski]

I'm by no means kernel or mplayer hacker and I barely know C, so I can't
guarantee _anything_ about information presented below... :-)

To compile and use mga_vid under recent 2.5.x kernel small changes have to
be done to the code:

---------------


simple_strtol is exported since 2.5.31 and pci_dev structure changed in
2.5.48

Now, to take advantage of a new kernel build system use the following
Makefile:

---------------
ifneq ($(KERNELRELEASE),)
obj-m       := mga_vid.o

else
KDIR        := /lib/modules/$(shell uname -r)/build
PWD         := $(shell pwd)

default:
        $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
endif
---------------

It is pretty self-explanatory.

'make' should build the mga_vid.ko - the module itself (warning: you need
write access to kernel source dir!)

NOTE: To use matroxfb with current 2.5.x kernel you need to apply patch from:
ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/ called
mga-KERNELVERSION.gz
