OKAY So havent updated much since 5.12 cuz of various graphic driver issues. The only remaining one is "dpu encoder timeout" If not running compiz it will just slow you down and spam your log files to rediculous sizes. Unfortunatly compiz freezes so anything your working on is lost wo extreme measures. The dpu encoder seems to have become slightly less often with newer kernels. Whats in here well the cpu turbo freq is now considered a reg freq cuz so many patches over so many kernel versions couldnt get it to work, like it simply wouldnt go into that freq ever. Now all is good. Using slightly older sound stack cuz of breaks in recent versions. FTDI mpsse drivers for i2c and spi look into the tools/16ton folder for support. Also an actual schematic for this laptop! Is in tools/16ton as well. As per usual the various wifi restrictions for ath10k have been removed no more no-ir/radar/tx-power limits from crda or from AP, all of 2.4ghz is open etc. I hardbake the regulatory.db file directly into the kernel but the crda/wireless-reg files I used are in tools/16ton. Some other various drivers for usb-to-i2c etc have been added and usb devices etc. Various little c630 fixes. I will mention altho it recovers from them fine the wifi driver has picked up some rather very common and intrusive issues as of late. Its unrelated to my wifi patches I always test seperatly. But dont be surprised if logs fill up with ATH errors. Oh and sound too no matter which sound stack they all have a ton of errors reported to logs. I was going thru and limiting the various log spammers, but I eventually got tired of keeping up with it. The information below is mostly legacy stuff tho sum may still apply. The supported hardware is old. Altho I havent personally tested the cellular modem has drivers and everything it needs, and I do believe the Displayport over usb-c has most, if not everything it needs. The DPort may need a out of tree patch or two I havent looked into it. kernel version 5.12.x apparently needs newer a630_sqe.fw I deleted my windows install so not sure if it came downin updates but i grabbed from here; https://anduin.linuxfromscratch.org/sources/linux-firmware/qcom/ seems to work fine for me so far This is for the qualcomm aarch64 laptop YOGA C630, with this kernel and these directions expect the following WORKS; accelerated graphics panel audio speakers/headphones (no internal mic) wifi bluetooth usb touchpad/keyboard/touchscreen camera battery meter (UPDATE much better reporting now thanks to a patch found at steevs kernel) Venus video encoder/decoder CPU turbo/boost frequencies UNTESTED BUT POSSIBLE LTE cell modem (My understanding is it needs an active sim and connection to tower with active data connection to present, i have no sim) DisplayPort over usb-c (I don't have a cable, and we dont have a working usb type-c driver) DOESN'T'T WORK LTE cell modem (My understanding is it needs more work, like context channels, possible changes to sum protocols and ip tools) Internal mic (which i believe is some sorta mic array with its own firmware "qcwdsp850.mbn"?) Sensor Low Power Island (im not sure if this includes the accelerometer or just temp etc firmware files qcslpi850.mbn qcslpi850_cls.mbn ive found no patches/dev?) UPDATE: Big shout out to Steev , his kernel has become the defacto kernel for linaro, He keeps bringing in awesome UPDATE: patches, he introduced me to pwcli where i found the ath10k patches for not waiting on dead device (gamechanger) UPDATE: And on top of all that despite the extreme gap between our intelligence and skill he still gives me a hand. UPDATE: Thank you Steev!! https://steev.net/tags/c630/ https://github.com/steev/ ALL CREDIT GOES TO THE GODS AT LINARO, id list names but i dont know who everyone is and what they do. i was adding patches from at least a half dozen places before finding Anderssons github page. That guy must be like the Gandolph of awesome programmers, so so many patches have come from him. i digress anyway; This assumes you have already followed the directions from https://github.com/aarch64-laptops/build and you have the four services installed (NEWEST POSSIBLE SOURCE REQUIRED) and you followed wifi link at https://github.com/aarch64-laptops/build/blob/master/misc/lenovo-yoga-c630/wifi/README.md and the gpu link https://github.com/aarch64-laptops/build/blob/master/misc/lenovo-yoga-c630/gpu/README.md and then HOPEFULLY followed the ubuntu system upgrade instructions at the bottom of the README to ubuntu 20.04 newer versions of alsa and pulseaudio are required for ucm2 tho ucm did work and i believe didnt have the sync issues if using =>5.7kernels Booting the remote procs get the firmware from windows partition UPDATE: the c630/yoga_fw_extract.sh fil in kernel source has my hacked up celliwig yoga_fw_extract.sh for all this stuff and more. wget https://raw.githubusercontent.com/Celliwig/Lenovo-Yoga-c630/master/yoga_fw_extract/yoga_fw_extract.sh chmod +x yoga_fw_extract.sh ./yoga_fw_extract.sh kernel 5.5 and newer need a diff firmware directory sudo mkdir -p /lib/firmware/qcom/LENOVO/81JL sudo cp /lib/firmware/qcom/c630/* /lib/firmware/qcom/LENOVO/81JL/ we also need qcdxkmsuc850.mbn ipa_fws.elf qcvss850.mbn EXAMPLE; use same method to find sudo find /mnt -name qcdxkmsuc850.mbn (it may find multiple ls -la them and use the newest) INSTALL FIRMWARE; cp qcdxkmsuc850.mbn /lib/firmware/qcom/LENOVO/81JL ipa_fws.elf; use pil-splitter.py found in this kernels C630 folder or https://github.com/remittor/qcom-mbn-tools/blob/master/pil-splitter.py python2 pil-splitter.py ipa_fws.elf ipa_fws then copy the resulting files to /lib/firmware qcvss850.mbn is the firmware for venus enc/dec which currently doesnt work on c630.(UPDATE: VENUS WORKS NOW!) the venus mods link to mdt_loader which means it should be able to load the "full" .mdt file. ive tried both split and full it loads without the metadata error but doesnt reset. eitherway; SINGLE FILE METHOD; mkdir /lib/firmware/qcom/venus-5.2 cp qcvss850.mbn /lib/firmware/qcom/venus-5.2/venus.mdt SPLIT FILE METHOD; mkdir /lib/firmware/qcom/venus-5.2 python2 pil-splitter.py qcvss850.mbn venus cp venus* /lib/firmware/qcom/venus-5.2/ Now their are sum .jsn files that i dont know what are used for but well grabem in case git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git sudo cp linux-firmware/qcom/sdm845/*.jsn /lib/firmware/qcom/LENOVO/81JL/ BLUETOOTH firmwares are in linux-firmware/qca/* Now we want to add the required firmware files to the initrd but celliwig saved the day with initramfs-tools hook that does this for us wget https://github.com/Celliwig/Lenovo-Yoga-c630-packages/raw/master/initramfs-tools-firmware/initramfs-tools-firmware_0.1_all.deb sudo dpkg -i initramfs-tools-firmware_0.1_all.deb sudo update-initramfs -k $(uname -r) -c If installed on older kernel update /etc/initramfs-tools/firmware to look like this; qcom/LENOVO/81JL/qcdsp1v2850.mbn qcom/LENOVO/81JL/qcdsp2850.mbn qcom/LENOVO/81JL/qccdsp850.mbn qcom/LENOVO/81JL/qcadsp850.mbn GRUB; Grub needs a few boot options added. edit /etc/default/grub find the line; GRUB_CMDLINE_LINUX_DEFAULT="efi=novamap" and replace with GRUB_CMDLINE_LINUX_DEFAULT="efi=novamap pd_ignore_unused clk_ignore_unused" sudo update-grub (will update the new settings) INSTALLING KERNEL!!!!

TOUCHPAD After hundreds of hours of use my touchpad is wearing down. It now constantly does "Tap and Drag" and is always copying files and text accidently. The last ditch option is to turn this off. The official answer with dconf editor did not work for me but synclient did synclient TapAndDragGesture=0 UPDATE: I wrote an extremely simple gui for synclient found here https://github.com/bm16ton/syn-gui MODEM edit dts file (already in this kernel) and add the firmware find/download ipa_fws.elf from windows partition. use pil_splitter.py to split into files with prefix ipa_fws copy to firmware directory.it now shows in dmesg that the modem is booted. I cannot test further because i believe if i had an active sim once the modem connected to a tower and had data i would get a rmnet device that i could use ip to setup. something similiar to; ip link add link wwp0s20u5i2 name rmnet0 type rmnet mux_id 1 and use something like qmicli or modemmanager to get it going? UPDATE; Needs more things mainlined, will try and keep an eye on this USB PERIPHERAL unfortunatly the usb type-c stuff isnt working but we can boot with a port in peripheral (just cant switch to host without reboot) edit arch/arm64/boot/dts/qcom/sdm850-lenovo-yoga-c630.dts and change; &usb_1_dwc3 { dr_mode = "host"; }; to; &usb_1_dwc3 { dr_mode = "peripheral"; }; you can just compile the dtb with make dtbs, now boot with the new dtb file and install umtp from; https://github.com/viveris/uMTP-Responder start with umtprd-ffs.sh it requires the functionfs libcomposite kernel modules which i will add to the 16ton_defconfig FIXES; SHUTDOWN; the system will crash on shutdown if connected to wireless AP. FIX; add this script/service which disconnects wifi at start of shutdown, in C630 directory sudo cp C630/usr/local/bin/disconnect-wifi.sh /usr/local/bin/disconnect-wifi.sh sudo chmod +x /usr/local/bin/disconnect-wifi.sh sudo cp C630/etc/systemd/system/iw-disconnect.service /etc/systemd/system/iw-disconnect.service sudo systemctl enable iw-disconnect.service The system will crash on shutdown if firefox is running when starting shutdown, simply close firefox. UPDATE; After installing updates (i believe systemd was amongst the list) the wifi shutdown script no longer works for me, so I replaced my shutdown icon with this script; #!/bin/bash nmcli device disconnect wlan0 & /usr/local/bin/closeallapps killall /usr/lib/firefox/firefox sleep 1.3 mate-session-save --shutdown-dialog THE /usr/local/bin/closeallapps script contains; #!/bin/bash for n in $(wmctrl -l | awk -v name=$1 '$0 ~ name{print $1}'); do wmctrl -i -c $n; done USB; sum devices that use too little power will not enumerate, my hack is to add a resistor if possible, or use a usb vol/amp meter in-line. GTK SLOW WINDOW CREATION; The headphone/speakers fix script didnt catch do it manually and they will open fine. No idea the connection. LOOSE ABILITY TO RUN su OR sudo (just stalls/sits) shutdown with systemctl it doesnt need privlidges systemctl poweroff NOTES; If you do have a lock up or shutdown that fails/panics and reboots expect your next 3 boots to be wonky. Most likely the wifi or sound wont work then on next boot again one or the other wont work. Sometimes everything will work on the first or second boot but it still takes 3 to get normal. Not sure what causes this, if it was leaving hardware is a strange state i thought maybe booting windows would set things correct but the one time i tried it didnt. Commonly with remoteproc/wifi/etc crashes sudo and su will stop working. Rather then a harsh shutdown systemctl poweroff will shutdown the machine without the need for sudo/su
