Sigh again
Did a module only build for the i2c-mux and got it into the currently
running kernel with a force to bypass the no symbol version for
module_layout error.. figured it was safe enough given it was the
identical kernel config etc from the centos vault...
Anyway still failed.. though the module seemed to install and is showing
with lsmod no dmesg barfs..
I'll try a full kernel build tomorrow..

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
