Hi Again
Yep that fixed pulling in the saa7164: si2168 frontends:
[ 6778.591548] i2c i2c-15: Added multiplexed i2c bus 16
[ 6778.591556] si2168 15-0064: Silicon Labs Si2168 successfully attached
[ 6778.596252] si2157 13-0060: Silicon Labs Si2147/2148/2157/2158
successfully attached
[ 6778.597229] DVB: registering new adapter (saa7164)
YAY!!
Bottoms up!
What a painful process... first time I built the kernel from the rpm
source I must have stuffed something up and the resultant installed
rpm didn't have the module turned on.. aaarrrrggghhhhh...
Trying to rebuild the srpm again after tweaking the .config file and
copying it around to the various locations again just didn't work..
Eventually gave up and had to rip it all out and start afresh..
It's not that hard once you get the hang of it. I had to recompile
anyway, as I need saa716x, dvbloopback and backported drivers for DVBSky
T982, plus I need more then 8 dvb adapters. Semi-automated this of course:
https://github.com/bas-t/centos7-kernel
Well spotted on that one.. What a pain that the call to the i2c mux
create didn't result in a error :/
Now I just need to shutoff kernel updates..
Really need to push this up into the centos config.. I've noted that
it has been turned back on in other releases..
Will submit a bug.
Excellent idea. But as stated, I'll have to recompile anyway...

Hi, not sure if this is related.
I had to recompile the centos7 stock kernel with:
CONFIG_I2C_MUX=m
It was not enabled in the kernel config.

Sorry If I've posted this to the wrong section my first attempt..
Hi
I'm attempting to get an HVR2205 up and going.
CORE saa7164[1]: subsystem: 0070:f120, board: Hauppauge
WinTV-HVR2205 [card=13,autodetected]
Distribution is CentOS7 so I've pulled the v4l from media_build.git
Had to change a couple of things.. and another macro issue
regarding clamp() ..
Seems the kzalloc(4 * 1048576, GFP_KERNEL) in saa7164-fw.c was
failing..
kept getting: kernel: modprobe: page allocation failure: order:10,
mode:0x10c0d0
Have plenty of RAM free so surprised about that one.. tried some of
the tricks re increasing the vm.min_free_kbytes etc..
Any way I modified the routine to only allocate a single chunk
buffer based on dstsize and tweaked the chunk handling code..
seemed to fix that one.. fw downloaded and seemed to boot ok..
Next I'm running into a problem with the saa7164_dvb_register()
stage...
saa7164[1]: Hauppauge eeprom: model=151609
saa7164_dvb_register() Frontend/I2C initialization failed
saa7164_initdev() Failed to register dvb adapters on porta
I added some extra debug and identified that
client_demod->dev.driver is null..
However I'm now stuck as to what to tackle next..
I can provide more info, just didn't want to spam the list for my
first email..
Regards
Richard Tresidder
