Andy:

I went ahead and compiled and installed the kernel as I posted earlier using make localmodconfig / compressed modules and did some additional things like removed any support for all processors except AMD which was still enabled in menuconfig and a little tweaking to get gcc optimized for my processor's instruction sets per an arch wiki.

Some of the results are a little amazing.

The kernel size reduced a little (not much) from 6.9M to 6.7M

The amazing things:

I put the 2 module trees in an uncompressed tarball. Below the original UDL module tree is 4.11.0-rc5+.tar and the new localmodconfig-compressed module tree is 4.11.0-rc5+-localmodconfig.tar. As you can see the size from the 2 trees went from 3G to 54M:

mod-trees.png 

The time it took here to compile the new kernel / modules went from normally @90 min to 18 min:

localmodconfig-compile.png 

The total contents of my /lib/modules/4.11.0-rc5+/kernel/drivers/media/dvb-frontends/ directory and also showing the modules as being compressed:

And my 7301 works perfect. Also take a look at majortom's new Band Width mod he put under the BER. Kinda cool isn't it:

Ray,

Thanks for the 'make localmodconfig' info.  I can see where maybe my 'make allmodconfig' just got a lot easier.

Jim:

That would certainly disable all of the modules you are not using that make allmodconfig enabled; which is pretty much all of the modules possible get enabled. I can definitely see how it would help you out saving time and a headache to weed out the unwanted modules.

Did some thinking what you said tonight; have no idea why this issue you previously posted popped up in my mind but some of my usb ports here have the capability of being faster than the others for some reason. I wonder if you have tested plugging in your device in different ports on your computer.

Also in the back of my mind seems like I remember that a device pluged in a hub would lock in it's speed for that hub and another device plugged in the same hub would use that locked in speed. I could be wrong on this part; I have not read up on it in a long time. My old age could be making me dream things.

I have no usb speed glitches here with my devices.

I'm in a relearning phase.[confused]


USB might be fine to a point; it still has bandwidth bottle necks compared to pci.

Updated the media_build_udl system today, if anyone wants to try it.
https://bitbucket.org/majortom/media_build_udl
Installs the drivers from UDL's latest commit + a means access iq registers of lgdt3306a demod..

Also, decided to make a repo for firmware.
https://bitbucket.org/majortom/dvb-firmwares/overview

Might make it easier to add/subtract from the dvb-firmwares.tar.bz2 archive that media_build_udl
downloads. There were a few firmwares that UDL was including, that weren't in the original tarball,
so that's updated now too.

Sidenote:
These two files were in both the original tarball and UDL's tree, but they differ.. No clue what is actually different, but went with UDL's file
dvb-firmwares/dvb-demod-si2168-b40-01.fw differ
dvb-firmwares/dvb-tuner-si2158-a20-01.fw differ

I get this warning in dmesg with UDL's latest kernel. I wonder if anyone else has noticed it. It looks like it may have to be with fuse. My drives seem to be loading ok. I sure do not want any corruption.

This is on my desktop; not the rpi. UDL's kernel is at 4.12.0-rc1 and the arch-pi's raspian kernel is at 4.12.0-rc2 and it's fuse does not give this warning. It uses the same software version.

Thanks,

I guess it may have to be something with my hardware here then. My last fuse update was 21 days ago.

Code:

[2017-05-06 01:50] [ALPM] installed fuse2 (2.9.7-3)

In case any one has a 955Q this is what the IQ plot looks like.

Good job Majortom!!!!

I also was having issues with the fuse module on my MS Surface 3 but not on my main PC. I removed the moduel in the ,config and it seems to fix the issue.

Do a git pull as I just pushed the change

Here is another pic of majortom's 955Q IQ plot mod from my raspberry pi. Majortom has raised stv090x-iq program from the dead and it is alive and kicking now.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
