ppa kernel

Install ppa kernel on ubuntu20.04 via:

add-apt-repository ppa:tuxinvader/lts-mainline -y
apt update -y
apt-get install -y linux-generic-5.19

After reboot, check the kernel via:

# uname -r
5.19.3-051903-generic

Customization of Kernel

uncomment the deb-srcfor ppa:

# cat /etc/apt/sources.list.d/tuxinvader-ubuntu-lts-mainline-focal.list 
deb http://ppa.launchpad.net/tuxinvader/lts-mainline/ubuntu focal main
deb-src http://ppa.launchpad.net/tuxinvader/lts-mainline/ubuntu focal main
# apt update

Get the source code:

# apt install linux-source-5.19.3
# ls /usr/src/linux-source-5.19.3/
debian  debian.master  linux-source-5.19.3.tar.bz2

Get the build-dep for kernel:

# apt build-dep linux-generic-5.19
# apt build-dep linux-doc

Prepare the build tree:

# cd /usr/src/linux-source
# bunzip2 linux-source-5.19.3.tar.bz2
# tar xf linux-source-5.19.3.tar
# mv linux-source-5.19.3/* .
# mkdir debian/stamps

Build via:

# fakeroot debian/rules clean
# fakeroot debian/rules editconfigs
# fakeroot debian/rules binary-headers binary-generic binary-perarch

build will take sometimes, so drink a cup of H~~~ot tea and wait.

Check the built result:

# ls /usr/src/*.deb
/usr/src/linux-buildinfo-5.19.3-051903-generic_5.19.3-051903.202208220846_amd64.deb

Kernel upgrading

vfio in linux-zen, performance is bad.

# git clone git://mirrors.ustc.edu.cn/linux.git
# cd linux/
# git checkout tags/v5.19.3 -b 5.19.3

Steps

Install sddm:

# pacman -S sddm xorg

After reboot, examine the kernel and the sg1 pci infos:

[root@archvfio ~]# lspci | grep -i vga

07:00.0 VGA compatible controller: Intel Corporation SG1 [Server GPU SG-18M] (rev 01)

Linux archvfio 5.19.1-arch2-1 #1 SMP PREEMPT_DYNAMIC Thu, 11 Aug 2022 16:06:13 +0000 x86_64 GNU/Linux

Add virtio gpu into blacklist:

# vim /etc/modprobe.d/blacklist.conf
   # blacklist virtio_gpu

Didn’t take effects, change the graphical to qxl and added blacklist qxl:

/images/2022_08_15_14_23_35_535x518.jpg

Take effects:

[root@archvfio ~]# lsmod | grep qxl
[root@archvfio ~]# ls /dev/dri/
by-path  card0	renderD128

Examine the sg1 connected info:

for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done
DP-1: disconnected
DP-2: disconnected
DP-3: disconnected
HDMI-A-1: disconnected
HDMI-A-2: disconnected
HDMI-A-3: disconnected
HDMI-A-4: disconnected

Edit the Xorg configuration files and start the benchmark:

# vim /etc/pacman.conf

sudo apt-get install gcc-10 g++-10
git config --global user.email "you@example.com"
git config --global user.name "Your Name"

Get the repo from ustc.edu.cn, and replace the repo for proxy.

$ curl -sSL  'https://gerrit-googlesource.proxy.ustclug.org/git-repo/+/master/repo?format=TEXT' |base64 -d > ~/bin/repo
$ chmod a+x ~/bin/repo
## 如果提示无法连接到 gerrit.googlesource.com，可以编辑 ~/bin/repo，把 REPO_URL 一行替换成下面的：
## REPO_URL = 'https://gerrit-googlesource.proxy.ustclug.org/git-repo'

Repo init:

repo init -u https://github.com/BlissRoms-x86/manifest.git -b r11-r36

Repo sync(Using redsocks):

repo sync -j8

After repo sync:

cd prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6
git checkout 2078a6bf9e5479104cfe2cbf54e9602672bd89f7

Build via:

. build/envsetup.sh
lunch android_x86_64-userdebug
export NO_KERNEL_CROSS_COMPILE=true
export BLISS_BUILD_VARIANT=foss
mka iso_img -j8

The generated iso is listed as:

out/target/product/x86_64/BlissOS-14.3-x86_64-202207270925_k-_m-r11-r36.iso is built successfully.
