[R-engine-developers] New comer to r-engine

[Cedric C. <ri...@ha...>]

Hi !

I just get a second hand pcg-c1msx some days ago, and I'm willing to 
have the motion-eye working (not that I really need it, but as a coder 
it's challenging).

I tried your code and play a little with it. I mostly get the same 
results than you (SAA7113 Fail, mb86393 recognized).

So, just to be sure I understand what we have : The camera send its flow 
to a Phillips SAA7114 wich then send it to the Fujitsu mb86393, both 
circuit beeing given the name 'r-engine' by sony. The mb86393 is a PCI 
device and the code a driver of another engine ('Triumph' driver) was 
given by Fujitsu (considering japanese comments and documentation). The 
mb86393 and the saa7114 communicates via i2c. In the driver given by 
Fujitsu, the mb86393 was used with the SAA7113 instead, wich is a 
similar but simplier chip. We do not care because we know everything 
about the saa7114 thanx to previous work in media/video.

Am I right ?

If so, can I ask you a question : how do we know for the saa7114 ? The 
information comes from sony/fujitsu, or is it just a guess based on chip 
recognition ? I ask because I tried to read some of its registers 
without success.

Then, if it turns out to be a sa7114, why not reusing fully the sa7114.c 
by coding the mb86393 driver as a pci_device *AND* as a i2c_adapter ? 
Maybe I'm just too unfamiliar with the linux internal designs...
