[linux-dvb] Twinhan VP1020 and EM8300 (dxr3) under 2.6.3 ????

["Oliver Derks" <oli@linux-jungs.de>]

Hello everybody....

I have problems running my em8300 card TOGETHER with the twinhan DVB card
under kernel 2.6.3 ....

has anyone tried this?????

here are the details:

the em8300 card:

00:0d.0 Multimedia controller: Sigma Designs, Inc. REALmagic Hollywood Plus
DVD Decoder (rev 02)
        Flags: bus master, medium devsel, latency 64, IRQ 12
        Memory at cfe00000 (32-bit, non-prefetchable) [size=1M]
        Capabilities: [40] Power Management version 1


the twinhand dvb card:

00:09.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (
rev 11)
        Flags: bus master, medium devsel, latency 64, IRQ 11
        Memory at cdbfe000 (32-bit, prefetchable) [size=4K]
        Capabilities: [44] Vital Product Data
        Capabilities: [4c] Power Management version 2

00:09.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11
)
        Flags: bus master, medium devsel, latency 64, IRQ 11
        Memory at cdbff000 (32-bit, prefetchable) [size=4K]
        Capabilities: [44] Vital Product Data
        Capabilities: [4c] Power Management version 2


here is my module load/unload script for dvb:

#!/bin/sh
case "$1" in

  start)
          modprobe bttv card=0x71 i2c_hw=1

## the 0x68er card does nt work for me, freezes the system.....

          modprobe dvb_bt8xx
          modprobe dst dst_type=0 dst_type_flags=1
        # modprobe dst dst_type=0
  ;;

  stop)
        rmmod dst
        rmmod dvb_bt8xx
        rmmod dvb_core
        rmmod bt878
        rmmod tuner
        rmmod bttv
        rmmod i2c_algo_bit
        rmmod video_buf
        rmmod btcx_risc
        rmmod i2c_core
        rmmod videodev
        rmmod v4l2_common
        lsmod
   ;;
  *)
        echo "Use: dvb {start|stop}" >&2
        exit 1
   ;;
esac
here is the dmesg output:

took me quite a while to get that far.... 
...loading the bttv driver always froze the system....
until i made everything new from scratch with gcc 3.3 and kernel 2.6.3.
this part seemed (!) to be working fine....
watching tv with "xine dvb://" was possible.....


now to the em8300/dxr3
----------------------

to get my em8300/dxr3 card working i patched my kernel tree with 

http://www.jburgess.uklinux.net/linux-2.6.0-test9-dxr3.patch.bz2

from Jon Burgess (thanks man) , and after a little tweaking it worked for my
card.....
...here ist the shellscript:

#!/bin/sh
case "$1" in

  start)
         /sbin/modprobe i2c-algo-bit
         /sbin/modprobe adv717x pixelport_16bit=0
         /sbin/modprobe em8300 dicom_control=0
         em8300setup -f /usr/share/misc/em8300.uc

;;

  stop)
        fuser -k /dev/em8300-0
        fuser -k /dev/em8300_mv-0
        fuser -k /dev/em8300_ma-0
        rmmod em8300
        rmmod adv717x
        #rmmod bt865
        rmmod i2c-algo-bit
        rmmod i2c-core
   ;;

  *)
        echo "Use: dxr3 {start|stop}" >&2
        exit 1
   ;;
esac


here is the dmesg output:
 PCI: Found IRQ 12 for device 0000:00:0d.0
 em8300: EM8300 8300 (rev 2) bus: 0, devfn: 104, irq: 12, memory: 0xcfe000

 em8300: using MTRR
 em8300_main.o: Chip revision: 2
 adv717x.o: ADV7170 chip detected
 em8300: Microcode version 0x29 loaded

....i could play mpeg-files via "mplayer .vo dxr3" 
except for this:

which is constantly repeated during playing... first i thought i uses the
wrong includes while compiling kernel 2.6.3 (i did!) but changin them to the
proper kernel tree and recompiling mplayer did`nt change anything......

despite the error the card is playing anything fine and responding to the
em8300setup program....

but when i load the dvb driver it freezes the system again.....

..funny thing is i have to switch of the computer after this for a few
minutes, cause otherwise it waits forever before bootin at: "Checking NVRAM.."

so i guess there is some serious irq routing problem involved....
...(desperately) i tried to change some cards around and diabled some irq
using stuff in the bios... but guess what.... no go...:(((

after using linuxtv-1.1.1 on the kernel and recompiling nothing works
anymore...(okay i had to copy some things aroung to get the em8300 driver into
the kernel again, i guess i should`nt have done that, or probably patched it
properly with jons patch again????)

i am downloading 2.6.4. at the moment.... and start clean over again....

unless someone has some hints for me.....

sorry if i forgot something or just asking stupid questions... 
i am more or less just stumpling aroung......

any help would be appreciated

thanks
oli
