I have upgraded my kernel to fix a certain VIA/IDE card driver problem. Unfortunately,
I am having difficulty getting the video capture drivers going...
Normally, I build the zoran 0.8 driver, but the build falls over like this:
zoran.c: In function `zr36057_init':
zoran.c:4260: too few arguments to function `video_register_device_R3a7ce584'
make[2]: *** [zoran.o] Error 1
make[2]: Leaving directory `/big/samba/Other/LinuxBits/Video/Current/zoran-driver-0.8'
So, I presume the interface has changed. However, looking at what IS provided
in the 2.4.9 kernel, there is a driver zr36067 module that seems to take
the same options/arguments as the zoran driver. The system logs indicate:
Aug 29 11:36:25 gate kernel: Zoran ZR36060 + ZR36057/67 MJPEG board driver

OK, so it appears to be an earlier 0.7 version of the driver, but I remember
this used to work. The problem I am getting occurs when I try to use any
tools, like xawtv, or lavrec:
Aug 29 11:36:34 gate kernel: DC10plus[0]: No bigphysarea_patch present, usage
of high memory disabled,
Aug 29 11:36:34 gate kernel: DC10plus[0]: sorry, could not allocate V4L buffers
of size 1280 KB.
Aug 29 11:36:34 gate kernel: DC10plus[0]: zoran_open: v4l_fbuffer_alloc failed
Now, I would have thought this big physarea facility would be in 2.4.9 by
default. Is there anything I need to do to configure this kernel? Or where
do I get this patch from? Or is the bigphysarea_patch error message a red
herring? I reserve memory using [append=" quiet mem=505M"] in the lilo boot
configuration, so it's not as if the memory isn't there.
Suggestions? Ed-T.
