kernel-6.8.4-expSEHDsec-fsync-fcpu-RPMs 07-15-2024 (still 6.8.2 running)

!!! NEW BIG FIX IN CPU FUNCTION RATE FOR FASTER CPU "JIFFIES/MIPS" PER CYCLE

20-30 second boot time and now every single process running with ps ax is slightly faster from faster jiffies rate

lest we remember how "jiffies" work before the MIPS era (machine instructions per second)

grub now requires vga=845 in the /etc/default/grub and /boot/grub2/grub.cfg in order to show the penguin logo on boot

vga=845 is video mode 34D on my system its 1920x1080x32 or vga=913 video mode for 1920x1080x24

testing events at boot now takes 15 seconds instead of 3 minutes to register kobjects and to check event inside of nodes

BUG IN CRYPTSETUP WITH LUKS FOR RHEL/FEDORA and DEBIAN/UBUNTU SYSTEMS

• build from source

to make a small rpm use disable-debugging in the kernel source folder where .config is located after running make menuconfig




disable-debugging-info.sh


build from source update

# fedora 39/40

make -j24 binrpm-pkg

# debian11

apt install bc cpio kmod libelf-dev:native libssl-dev:native rsync debhelper devscripts lsb-release build-essential linux-source bc kmod cpio flex libncurses5-dev libelf-dev libssl-dev dwarves bison bc kmod cpio flex libncurses5-dev libelf-dev libssl-dev dwarves bison libc-dev

directory should match the CWD for KERNELRELEASE=
./linux-image-6.8.3-c4pt000-expSEHDsec-fsync

make -j24 bindeb-pkg KERNELRELEASE=6.8.3-c4pt000-expsehdsec-fsync KBUILD_BUILD_VERSION=72

# requires updating to newer systems with newer dracut Fedora 39 and newer

# Tested working 100% on Fedora 39 (Fedora 35 is not supported for 6.8.2)

# Fedora 39 and up might or might not work on Fedora 35

Fedora 35 has an older dracut version that doesnt support missing "CONFIG_MICROCODE_[intel/amd]" from the kernel config

so the only way to install with rpm -ivh --force kernel-6.8.2****.rpm is to use dracut version 0.59.1 and higher or 0.60.0 dracut with newer systems like Fedora 39 and or Debian bookwork possibly

Same functions as 5.11.6 for experimental hardened security functions only new updates now for security features in the virtualization options ("kobject" kernel-objects, event tracing, BATMAN mesh networking for wifi clusters, RENO TCP instead of CUBIC TCP, hardened Selinux policies when they are actually enabled with enforcing, hardened memory stack, faster more responsive Dyanamic Tick for the processor and BUS when the governor starts clocking through the bitstream

right now HAXM has to be installed manually from the tar.gz its not part of the kernel-devel package for /usr/src/kernels right now

./haxm-install.sh
modprobe haxm
lsmod | grep haxm
