[01:56] <gunchyo> if anyone isa round, curious how I can get uhm
[01:56] <gunchyo> IO data from a card
[01:56] <gunchyo> such as dbm, SNR
[01:56] <gunchyo> all that information. thanks.
[02:37] <Broly> check the PCI library functions?
[02:39] <gunchyo> dvb-fe-tool -m seems to be what I wanted
[02:42] <Broly> answered your own question! :)
[02:42] <gunchyo> yes :)
[02:42] <gunchyo> now just trying to get proper info to tvheadend...
[02:42] <gunchyo> 84% signal strength when -72dBm :/
[02:42] <gunchyo> and old card shows 59% strength, can't get dBm
[02:44] <Broly> fe_read_snr is a legacy function from what the docpages say, so maybe it won't work. but you said it's an older card that can't get it, so i dunno
[02:44] <Broly> https://linuxtv.org/downloads/v4l-dvb-apis-new/uapi/dvb/dvbapi.html (if you're not already there. you probably are)
[02:44] <gunchyo> someone mentioned looking at "the media tree for  better drivers"
[02:44] <gunchyo> how would I find what driver my card is using
[02:44] <Broly> try lspci
[02:45] <Broly> or lsusb if it's connected via usb
[02:45] <Broly> lspci -nnv
[02:46] <gunchyo> uhhh
[02:47] <gunchyo>  Pericom Semiconductor Device
[02:47] <gunchyo> thjink it's this one
[02:47] <gunchyo>  Kernel driver in use: pcieport
[02:47] <gunchyo>         Kernel modules: shpchp
[02:47] <Broly> there you go
[02:47] <Broly> shpchp i guess
[02:47] <gunchyo> so is this old or
[02:47] <gunchyo> er no
[02:47] <gunchyo> this is wrong
[02:47] <Broly> yup
[02:47] <Broly> you're right
[02:47] <Broly> that's just the pci driver stuff
[02:47] <gunchyo>  CX23887/8 PCIe Broadcast Audio and Video Decoder with 3D Comb
[02:47] <gunchyo>  Subsystem: Hauppauge computer works Inc. WinTV-quadHD
[02:47] <gunchyo> there it is
[02:47] <gunchyo>  Kernel driver in use: cx23885
[02:47] <gunchyo>         Kernel modules: cx23885
[02:48] <Broly> ther you go (i'm not familiar with tv cards i thought the pericom may have been it, didn't know you weren't sure)
[02:48] <Broly> the driver is fine
[02:48] <Broly> it's mainline
[02:49] <gunchyo> ok
[02:49] <gunchyo> someone mentioned before it has issues rn
[02:49] <Broly> https://www.linuxtv.org/wiki/index.php/Conexant_CX23885/7/8 not much documentation though on the official page
[02:49] <Broly> it's possible

[02:49] <gunchyo> and etc junk
[02:49] <Broly> you're using 4.14 etc?
[02:50] <Broly> https://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-quadHD_(DVB-T/T2/C)
[02:50] <Broly> Firmware
[02:50] <Broly> Requires dvb-demod-si2168-b40-01.fw, this is available through OpenELEC dvb-firmware repository
[02:50] <Broly> Drivers
[02:50] <Broly> Included in Linux Kernel v4.8. All 4 tuners working, able to watch TV.
[02:50] <gunchyo> 4.13
[02:50] <gunchyo> I use atsc
[02:50] <Broly> yeah more than recent enough
[02:50] <Broly> i guess that page is your best shot as a starting point
[02:51] <gunchyo> someone suggested i enable LNA
[02:52] <Broly> you're going to have to play with some settings, i imagine
[02:53] <Broly> default may not work very well. so take some care, but also don't be afraid
[02:54] <gunchyo> i am afraid
[02:54] <gunchyo> I don't wanna break anything :S
[02:55] <gunchyo> i thought this new card would be the be all end all that'd fix all my problems :(
[03:37] <gunchyo> thanks for all the help broly and b-rad :)
[03:37] <gunchyo> bye for now
[17:22] <Kobaz> izza broken
[17:22] <Kobaz> make[3]: *** No rule to make target '/home/kobaz/download/media_build/v4l/frame_vector.c', needed by '/home/kobaz/download/media_build/v4l/frame_vector.o'.  Stop.
[17:23] <Kobaz> master branch, f709aa4... media_build
[17:24] <Kobaz> full build log coming up in a few
[17:27] <b-rad> sounds like 4.2 backport didn't happen
[17:28] <Kobaz> most of it builds...
[17:28] <Kobaz> so it seems
[17:28] <b-rad> 4.2 is missing frame_vector.c
[17:28] <Kobaz> ah
[17:29] <Kobaz> https://pastebin.com/fdjrF6hn
[17:31] <b-rad> what kernel are you building for? because the system thinks 4.14.4
[17:33] <Kobaz> Linux markm 4.14.4 #1 SMP PREEMPT Sat Dec 9 13:45:54 EST 2017 x86_64 GNU/Linux
[17:40] <b-rad> interesting, i wonder why it's not finding it in your installed headers. The symbols are all exported so I wouldn't think the need to pull in the .c file
[17:40] <b-rad> you'll have to wait for someone more knowledgable about that detail
[17:53] <Kobaz> well
[17:53] <Kobaz> heh
[17:53] <Kobaz> the file's not there
[17:53] <Kobaz> find . -name frame_vector.c
[17:53] <Kobaz> nuttin
[17:54] <Kobaz> oh
[17:54] <Kobaz> i see
[17:55] <Kobaz> it's all symlinks into ../linux/drivers
[17:58] <Kobaz> okay so ./mm/frame_vector.c is a kernel item
[17:58] <Kobaz> yeah looks like it missed a symlink in the setup
[17:59] <Kobaz> markm {~/download/media_build/v4l} kobaz$ ln -s /usr/src/linux/mm/frame_vector.c
[17:59] <Kobaz> that did it
[18:06] <Kobaz> it built, yay
[18:21] <Kobaz> something is pretty wrong with the build setup
[18:21] <Kobaz> [1725402.898562] WARNING: You are using an experimental version of the media stack.                        As the driver is backported to an older kernel, it doesn't offer
[18:21] <Kobaz> 4.14 being flagged as an 'older kernel' ?
[18:33] <Broly> it's probably something that detects a mismatch between the kernel the driver was released with, and the kernel it is being used on
[18:33] <Broly> so it's the wrong thing to say, but it's being tripped for the correct reason (which is that the kernel the driver shipped with, does not match the one it is currently being used for)
