Subject: cx88-dsp.c: missing __divdi3 on 32bit kernel
Date: Mon, 06 Apr 2009 22:40:38 +0200 [thread overview]

Hello,
Commit 02fde69f31dc (and 7152a23142bc) on http://linuxtv.org/hg/v4l-dvb/
adds new file cx88-dsp.c which uses 64bit divisions, but these are somehow
not supported on 32bit kernels.
message during compile:
WARNING: "__divdi3" [/root/v4l-dvb/v4l/cx88xx.ko] undefined
Maybe we can use only s32, but I don't know if it's precise enough for that magic math.
Or use some ugly hacks to do 64bit division with 32bit variables.
What hardware do I need to test the cx88-dsp code?
Any suggestions?
- Miroslav
