Current has mesa 23.1.3 and kernel 6.1.

Been a while since i built a kernel. Way i did it was (as root):

• download from kernel.org into /usr/src/ (wget https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.4.3.tar.xz for example)
• cd /usr/src/ and tar xvf the-downloaded-tarball
• rm linux - it's a link to kernel source, so that programs can compile against the kernel (rarely necessary)
• ln -s linux-downloaded-one linux - makes new link to downloaded kernel
• cp linux-installed-kernel/.config linux/ - copy the old config to the new
• cd linux then make oldconfig - a lot of questions about all the new options, that should include the new arc drivers if they are not included into old ones
• make menuconfig or make nconfig - are TUI-s to configure the kernel. nconfig has a search (F8)
• make bzImage modules - to compile the kernel and modules (basically shared libs)
• make modules_install - copies modules to /lib/modules/version (important as most drivers are modules)
• cp arch/x86_64/boot/bzImage /boot/vmlinuz-version - copy the kernel core to /boot
• edit /etc/lilo.conf - if you use grub then idk
• go to bottom, copy the whole block including image = ... , keep the original to have a bootable kernel
• change /boot/vmlinuz to whatever i called mine
• run lilo
• reboot
• reorder lilo boot order if i forgot to before, and lilo then reboot again to confirm

Not the official slackware way, but.. actually slack is the slackware way. Have borked my system plenty of times and had to dig up the install cd/usb to fix it.

There is documentation on slackbook http://www.slackbook.org/html/system-configuration-kernel.html but it's a bit outdated. You can always ask questions on the official forum https://www.linuxquestions.org/questions/slackware-14/
