saa7134 >8 channels

[liviud]

Hello

I want to use 4 china boards with saa7x chipsets, so i have 16 channels.
everything ok, i tested this boards with ZM and it worked, but the problem appears when i need to use options, becouse when i try :

[root@atlantis usr]# modprobe saa7134 card=33,33,33,33,33,33,33,33,33,33,33,33,33,33,33,33
FATAL: Error inserting saa7134 (/lib/modules/2.6.24.3-12.fc8/kernel/drivers/media/video/saa7134/saa7134.ko): Invalid argument

dmesg:
card: can only take 8 arguments
saa7134: `33' invalid for parameter `card'

first 8 channels work, but the rest ... the same story:
saa7134[4]: subsystem: 1131:0000, board: UNKNOWN/GENERIC [card=0,autodetected]

any ideeas ?

I'd say that it's a limit of either the driver and/or the chip.

[liviud]

yea, i know that, but any ideea how to jump over that ?

[cordel]

Sorry mate, I don't code driver stuff so I can't be of any use there.

For saa7134 chipset this problem can be solved in few steps

1. download kernel sources
2. edit drivers/media/video/saa7134/saa7134.h , search for
#define SAA7134_MAXBOARDS 8
#define SAA7134_INPUT_MAX 8
and change values in what you need
3. compile
4. reboot and play

i hoppe this will help

[cordel]

Yeah but the question remains, does it work, meaning can you get all the inputs functioning at once?
I am sure the cap was there for a reason, maybe for the old pci buss since it can't handle much. So what results are you getting?

[liviud]

Yes is workin', i have video on all 16 inputs, i don't realy know why that limit is there but i see the same limit in bt* driver, and i think is the same limit in the driver.

PS. i've tested on nvidia and via moterboard's.

[cordel]

What chipsets?
Certain chipsets from both manufactures have issues with at least bttv, so this would be useful to know.

[liviud]

right now is workin' with saa7134, for bt* i will test soon

[cordel]

No I mean mainboard chip sets. Sorry I was a bit vague. BT878 has issues with some Nvidia, SiS, and Via chipsets. Mostly around the earliy P4 release time frame.

Glad to hear it
Still would be interested to hear how it performs though

[azir]

It runs well anyway, but I'm quite unsatisfied with full 8 monitor in montage so I grouped into 2 groups, each 4 monitor ..

It runs Zoneminder-1.23.2 on Slackware-12, just run as server, no monitor, keyboard, mouse. Only run services required by zm and me I need ssh
cam settings:
func = modect
size = 320x240, RGB24
buffer = default
MaxFPS = AlarmMaxFPS = 12

Browser Firefox 2.0.0.4 w/ config:
network.http.pipelining = true
network.http.proxy.pipelining = true
network.http.pipelining.maxrequest = 32
network.http.max-connections-* = 32
network.http.max-persistent-connections-* = 32

cpu load
idle = 0.51
peak = 1.96
this post http://www.zoneminder.com/forums/viewtopic.php?t=6419 seems work for me

I'm having the same iusse making work two 8 chip saa7134 cards at the same time on ubuntu server..

Have anyone got a patch to solve that?
