tumbleweedCarlFK: source vs binary package names00:01
mithroCarlFK: The front page only shows the src package name00:01
tumbleweedin the case of one binary package, I should probably have named the source the same as the binary00:01
CarlFKok, I kinda get it.  onto more fun.. ka boom :(00:02
CarlFKError! The directory /var/lib/dkms/vizzini/1.0.0/source/00:02

tumbleweedurgh, dkms stuff is hard to test in chroots00:05
tumbleweedso I hadn't tested that build00:06

tumbleweedah, yes, I can see the problem00:50

tumbleweedCarlFK: there's a new version published that should fix that01:15
mithrotumbleweed: merged!01:17
CarlFKtumbleweed: mithro DKMS: install completed.01:33
CarlFKwhat does that give me?01:33
tumbleweedit's the exar usb driver01:43
mithroCarlFK: with dkms you shouldn't need to recompile the module when a new kernel is installed01:57

CarlFKshouldn't I see it?02:03
CarlFK[email protected]:~/HDMI2USB-misoc-firmware$ ls /dev/ttyV*02:04
CarlFKthat has always worked02:05
CarlFKnever mind, now it is there.02:05
CarlFKI guess you need to un/plug it twice ...02:05
CarlFKtumbleweed: thank you so much for your packing wizzardry02:38
CarlFKif I may be so bold as to ask for more, the one that sets up the udev rule might be easy02:39
CarlFKbut I am talking on an empty stomach02:39
CarlFKso maybe I should go eat02:39
CarlFK bye02:39
tumbleweedCarlFK: that does set up a udev rule. is it not working?02:44
CarlFKtumbleweed:  oh..  I didn't know the udev was related to that02:46
tumbleweedit should create /lib/udev/rules.d/40-vizzini-dkms.rules02:46
CarlFKI have to go test crhome book and eat02:47
CarlFKsee ya02:47

CarlFK_florent_: mithro: does sending output to all 3 outputs (0,1,encoder) risk anything?21:46
CarlFKIt seemed to work ok, but I think I saw some chatter here that made me wonder21:46
mithro_florent_: I believe we have *just* enough bandwidth on the Atlys to do all 3 outputs and the 2 inputs at the same time21:47
mithroopps I mean CarlFK21:47
_florent_not sure it will work at 720p with the atlys, opsis is fine with that21:48
_florent_720p50 maybe21:49
CarlFKthe talk I recorded was 720p, all 3 outputs.  what is the 50 in 720p50 mean?21:50
mithro_florent_: isn't it quite late for you?21:51
mithro_florent_: I was wondering, does the Spartan-6 have enough IO bandwidth on the pins to do 1080p30/25/24 ? They claim that it can do 1080i60...21:53
_florent_what's the status of this: ?21:53

mithroCarlFK: see _florent_'s question :)21:54
CarlFK_florent_: mithro:  works fine now with that laptop.  want me to close it?21:55
CarlFKI am still trying to meet up with the chrome book that saw 2 resolutions.   but I would say that is a different problem that should get its own issue if it is still a problem21:56
_florent_ok, if you were not able to reproduce the EDID issue, then yes you can close the issue.21:57
_florent_1080p30 should be fine yes21:58
_florent_mithro: do you want to test 1080p?22:00
mithro_florent_: Yes22:01
mithro_florent_: if you fixed the base target, then we should be able to add "base" back into
tpbTitle: HDMI2USB-misoc-firmware/ at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at
_florent_yes base is fixed22:02
_florent_if you want to support 1080p30:22:03
_florent_- add a modeline for that22:04
_florent_- change the framebuffer size
tpbTitle: HDMI2USB-misoc-firmware/hdmi_in0.c at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at
_florent_- change the encoder buffer size
tpbTitle: HDMI2USB-misoc-firmware/JPEG_PKG.vhd at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at
_florent_not sure this last modification will fit22:06
CarlFK_florent_: given the way my Atlys is currently boxed, it would help if the defaults were different.  At least until Oct 3 ;)22:15
CarlFKwould that mess anyone up?22:15
tpbTitle: Create a HDMI2USB GUI controller · Issue #41 · timvideos/HDMI2USB-misoc-firmware · GitHub (at
_florent_do you want to write a script to configure the board?22:18
CarlFK_florent_: Oct 1,2  tumbleweed and me will  be doing pyconza - 2 rooms, new talk every 30 min.  if we have to reboot, it would be nice if it came up the way we needed it22:19
CarlFKI would prefer not to even have to run  script that changes from default to needed setup22:20
_florent_what configuration do you need?22:21
CarlFKinput from hdmi122:21
CarlFKoutput to 0,1,encoder - quality 8522:21
CarlFKoh yeah, encoder on :p22:22
CarlFKI keep forgetting to set that and wondering why things are working22:22
CarlFKhdmi 1 because that is how I currently have the board and cabled secured to the inside of a box.22:23
CarlFK720p (not sure if I should care what scan rate)22:26
_florent_OK, the only thing you have to do is changing these 3 lines22:26
tpbTitle: HDMI2USB-misoc-firmware/processor.c at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at
_florent_and generate the gateware22:26
_florent_(I'll build it for you is you are not able to built it)22:28
CarlFKthank you22:31
CarlFKheading home from coffee shop.  see you in 10 min22:39

CarlFKany chance you know what is needed to flash?23:07
*** CARAM__ has joined #timvideos23:07
CarlFKI reinstalled the OS on the box I use for flashing. hoping I don't need to install the IDE again23:08
mithro_florent_: I got most of the way through adding a command to the lm32 firmware which lets the user set an arbitrary EDID mode too - hoping to get that working tomorrow23:10
mithroCarlFK: it would be trivial to make that part of a udev script which runs on plugging in the Atlys or when the Atlys reboots23:11
CarlFKmithro: I suspect that is based on some shaky assumptions23:12
mithroCarlFK: like?23:13
CarlFKlike the commands don't change23:13
CarlFKrace conditions23:13
CarlFKthat I can even get udev script to fire at all23:14
CarlFKI am trying to make things simpler.  adding a script is the wrong direction23:14
mithroCarlFK: Well, compiling your own firmware is very simple - I have been trying to show you how you can customize it23:15
CarlFKmithro: I don't want to deal with a fork23:17
mithroCarlFK: make the changes and send them in a pull request and see if we'll merge them23:17
CarlFKwhich is another thing in the opposite direction of simple23:17
mithroCarlFK: the probably answer is yes23:17
mithroCarlFK: but it is easier to merge once you have it working and happy with the settings23:18
mithroCarlFK: and saves you having to wait for us to make the changes for you23:19
CarlFKI am pretty happy with the way things are going23:19
