| giuliano | Hi. I'm building a uvcvideo.ko module, but have difficulties loading the new module on the system. May I ask for some help ? | 16:51 |
|---|---|---|
| giuliano | I opened bug 2000947, and received from laurent.pinchart@ideasonboard.com some c code to test... | 16:52 |
| -ubottu:#ubuntu-kernel- Bug 2000947 in linux (Ubuntu) "UVC Quanta 0408:4035 camera PROBLEM" [Undecided, Confirmed] https://launchpad.net/bugs/2000947 | 16:52 | |
| giuliano | yes | 16:52 |
| giuliano | this is the ghithub I'm testing right now | 16:52 |
| giuliano | https://github.com/Giuliano69/uvc_driver-for-Quanta-HD-User-Facing-0x0408-0x4035- | 16:52 |
| giuliano | I made a script to compile the module. The compilation ends correctly | 16:53 |
| giuliano | BUT the module is non loaded | 16:53 |
| giuliano | Hope the bash is well documented... what am I missing ? | 16:53 |
| giuliano | I see two main problems: | 16:54 |
| giuliano | 1) the dmesg shows this error failed to validate module [uvcvideo] BTF: -22 | 16:54 |
| giuliano | 2) there is a version mismatch between $ cat /proc/version_signature shows Ubuntu 5.15.0-57.63-generic 5.15.74. | 16:55 |
| giuliano | and modinfo uvcvideo.ko | 16:55 |
| Jeremy31 | giuliano: I just commented on your bug | 22:10 |
| giuliano | thanks Jeremy ! I saw your messagge on launchpad.. | 22:29 |
| Jeremy31 | giuliano: It is how I do bluetooth patches and I didn't see any module version issue with my method | 22:30 |
| giuliano | I installed inux-modules-extra-$(uname -r) where `uname -r` is 5.15.0-57-generic BUT .. | 22:31 |
| giuliano | The directory /usr/src/linux-headers-5.15.0-57-generic/drivers/media/usb/uvc/ has got only two make files, no C lang. File… | 22:31 |
| giuliano | do you mean a different directory ? | 22:31 |
| Jeremy31 | giuliano: You need the source code for linux-modules-extra | 22:32 |
| giuliano | I entered "sudo apt-get source linux-modules-extra-$(uname -r) | 22:32 |
| giuliano | " | 22:32 |
| giuliano | and it pulled 2045Mb... | 22:32 |
| giuliano | 204 | 22:32 |
| Jeremy31 | Don't use sudo for that | 22:32 |
| giuliano | Reading the console I now see... "dpkg-source: Informazioni: extracting linux in linux-5.15.0 | 22:34 |
| giuliano | " | 22:34 |
| Jeremy31 | Hopefully it isn't owned by root | 22:34 |
| giuliano | I ran the command from my home directory... | 22:35 |
| Jeremy31 | It might have different permissions | 22:36 |
| giuliano | hops... it created a new dir in my home .... owned by root.... | 22:36 |
| giuliano | gonna change the owner... | 22:36 |
| Jeremy31 | That will simplify things | 22:37 |
| giuliano | ok ... changed owner:group.. | 22:39 |
| giuliano | ok... the directory has got the c file inside... | 22:39 |
| giuliano | I would kindly ask... | 22:40 |
| Jeremy31 | Rename the original and copy the patched version in | 22:40 |
| giuliano | I've got in /usr/src/ a BIG tar file linux-source-5.15.0.tar.bz2 | 22:40 |
| giuliano | I used that file, extracting in my home and compiling | 22:41 |
| giuliano | that tar file is 153 MB but expanded got 1-2 Gb.... | 22:41 |
| giuliano | Shouldn't it be the ALL linux kernel ? Why I need to downlaod the linux-extra inf already is present that tar file ? | 22:41 |
| Jeremy31 | Just eliminating some possible problems with that linux-source file | 22:42 |
| Jeremy31 | I am not real sure how your built module ended up with vermagic of 5.15.64 | 22:43 |
| giuliano | renamed and downloaded the uvcvideo.c | 22:44 |
| giuliano | Should I run "make -j4 -C /lib/modules/$(uname -r)/build M=$(pwd) modules" in the top level of ~/linux-5.15.0 I just created ? | 22:45 |
| giuliano | or in the uvc dir ? | 22:46 |
| Jeremy31 | Run it in the uvc directory | 22:46 |
| Jeremy31 | Faster | 22:46 |
| giuliano | Skipping BTF generation for /home/giuliano/linux-5.15.0/drivers/media/usb/uvc/uvcvideo.ko due to unavailability of vmlinux | 22:46 |
| Jeremy31 | normal | 22:47 |
| giuliano | ?? | 22:47 |
| giuliano | what does it mean ? | 22:47 |
| Jeremy31 | IIRC it means Secure Boot is disabled | 22:47 |
| giuliano | my previous compileed module, failed modprove because "failed to validate module [uvcvideo] BTF: -22" | 22:47 |
| giuliano | is something similar with BTF ? | 22:48 |
| Jeremy31 | giuliano: Is there a uvcvideo.ko file in the directory now? | 22:48 |
| giuliano | yes, AND vermagic: 5.15.0-57-generic SMP mod_unload modversions | 22:48 |
| Jeremy31 | Copy it to the kernel | 22:49 |
| giuliano | cat /proc/version_signature | 22:49 |
| giuliano | Ubuntu 5.15.0-57.63-generic 5.15.74 | 22:49 |
| giuliano | Is the .63 missing ? | 22:49 |
| Jeremy31 | That is normal also, check in terminal> uname -r | 22:52 |
| giuliano | COPIED into /lib/modules/5.15.0-57-generic/kernel/drivers/media/usb/uvc | 22:53 |
| giuliano | should i change owner:group befor modprobe ? | 22:53 |
| Jeremy31 | No need to do that to anything in /home | 22:53 |
| giuliano | well... destination file was copied in system path /lib/modules/... | 22:54 |
| giuliano | and file shows | 22:54 |
| giuliano | -rw-rw-r-- 1 giuliano giuliano 4386720 gen 9 23:46 uvcvideo.ko | 22:54 |
| Jeremy31 | And using sudo to copy into /lib/modules already changed it | 22:54 |
| giuliano | I thougt... but checking ... it has not (?))) | 22:55 |

| giuliano | Well... I can get back to Pinchart.... the Cheese program is running | 22:56 |
| giuliano | and I can see myself in the window... BUT it is very slow.... extremely slow... | 22:57 |
| giuliano | thanks a lot for your help | 22:58 |
| Jeremy31 | Good luck | 22:59 |
| giuliano | thanks... | 22:59 |
| giuliano | I will try to fix this for all the other that have similar problem | 23:00 |
| Jeremy31 | If he has any new updates run this in the source directory before trying to make modules again> make -j4 -C /lib/modules/$(uname -r)/build M=$(pwd) clean | 23:00 |
| giuliano | you mean to run it in the uvc directory or in the root of the source ? | 23:02 |
| Jeremy31 | The linux-5.15 uvc directory in /home | 23:03 |
| giuliano | ok | 23:04 |
| giuliano | BTW I've got also another bug with the screen luminisity control. I can see the OSD reacting to my key pressed, but the screen does not change intensity. | 23:05 |
| giuliano | Even the top menu screen luminosity slider does not work… | 23:05 |
| giuliano | Strangely, I installed https://github.com/lordamit/Brightness, and it works… | 23:05 |
| giuliano | Where do you suggest me to start inspecting the code ? | 23:05 |
| giuliano | may be something ACPI related, or something at more higer leverl (gnome) ? | 23:05 |
| Jeremy31 | I have no clue, most of what I do is with wifi and bluetooth, but I can fix some issues compiling drivers | 23:07 |
| giuliano | ?? wifi ?? I noticed a failure about wifi in the dmesg.... but then it said it was loaded something... | 23:14 |
| giuliano | [ 3.286067] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-so-a0-hr-b0-66.ucode failed with error -2 | 23:14 |

| giuliano | Is someting to not working properly ? | 23:14 |
| Jeremy31 | giuliano: Normal for iwlwifi, the max and min firmware versions are specified in the module but it seems that version 65 or 66 aren't available so version 64 loaded | 23:17 |
| giuliano | thanks again for your help | 23:17 |
| giuliano | gonna inform Pichard of the progress !! | 23:18 |
| giuliano | Have a nice day ! | 23:18 |
| Jeremy31 | Good, later | 23:18 |
