Hi,
I am trying to unify the build and setup of the DVB drivers for use
with multiple DVB-IP providers and Digital TV.
I use siemens-0.8.2 because I can't upgrade to 2.4 kernel yet (other
drivers are not yet supported) and 0.9 won't compile with syntax errors.
(odd, but deffered for the moment).
My system is a Slackware 7.0, with glibc 2.1.3 and kernel 2.2.19.
Trying to figure out the parameters for the modules, I came across some
variables I can't really figure out. Maybe some of you can, please, help
me: (correct me and fill in the blanks)
i2c_core.o:
debug=1 print debugging information
videodev.o: ?
saa7146_core.o:
mode=0(PAL), 1(NTSC)
buffers=2(double buffering), 4(more buffers for high performance
capture.
debug - debugging levels
saa7146_v4l.o:
debug=1 print debugging information
VES1893.o:
debug - debugging levels
VES1820.o:
debug - debugging levels
dmxdev.o: ?
dvb_demux.o: ?
dvb.o:
debug=1 print debugging information
fdebug ?????
vidmem ????? (allocate memory for video what? buffers? what units does
it use?)
vidlow ?????
outstream ?????
vidmode=CVBS_RGB_OUT (default). Analog output enabled (RCA connector on
back plate).
=NO_OUT. disable analog output
=CVBS_YC_OUT ???? (Y/C output on cards that have an S-Video connector
?)
(Y/C output on internal on-board connector? If so,
what's the pinout?)
(simultaneous with CVBS output on RCA connector)
=YC_OUT ????? (Only Y/C output, on what connector?)
??????? How do I enable the RGB outputs of the SkyStar 1 card ? (related
to this parameter?)
napi=1 ???? (napi=new api?)
init_chan=0 (default) show Pro7 on analog output when loading module.
Dish on Astra 1.
=2 show n-tv on analog output when loading module.
Dish on Astra 1.
why both predefined set to Astra 1?
tuner.o:
debug=1 print debugging information
type=-1 (default) tuner type. As defined in tuner.h
Not sure how it is automatically selected for the existing
card.
addr=0 (default)
Not sure how this is automatically set.
in i2c.h:
I don't really understand when and how this is used.

msp3400.c is never refered to in the Makefile.
What cards exactly do use this audio chip ?
ost/src
--------
dvbdev.o
demux.o
dmx.o
video.o
audio.o
sec.o
frontend.o
ca.o
--------
None of them seem to need parameters.
------------------------------------------------------------------------
makedev.napi :
mknod -m 0666 /dev/ost/ca2 c 249 1
device ca2 has MINOR=1 same as device ca1 while all other devices2 have
MINOR=2.
Is this a feature or a typo ?
------------------------------------------------------------------------
dvb_ost.c seem to be rewritten into dvb.c. Is it needed anymore ?
------------------------------------------------------------------------
dvb_comcode.h contains comments in german. Can someone help me translate
?
// Vereinbarung der Command/Message Codes und der Statusbits
// Verwendung im ARM UND im C++ Projekt
#define SECTION_IPMPE 0x0C // bis zu 4k gro_
#define SECTION_HIGH_SPEED 0x1C // vergré±›erter Puffer fnr High Speed
Filter
#define DATA_PIPING_FLAG 0x20 // fnr Data Piping Filter
------------------------------------------------------------------------
dvb_dpram4k.h contains comments in german. Can someone help me translate
?
/* Definition der Speicherbereiche und Register des
DPRAM (von PC aus gesehen) und des DRAM (am AV7110)
*/
------------------------------------------------------------------------
Makefile contains rules to build the firmware but the files are missing.
Shouldn't these rules be removed from the distribution ?
------------------------------------------------------------------------
ost/src/Makefile
test: test.o $(OBJS)
$(CC) $(CFLAGS) -I../include -o test $< $(OBJS)
This rule does not refer to any existing file.
