Slackware ARM : Project Road Map

This road map represents intentions rather than commitments, but gives you some insight into some of the ARM-specific enhancements in the pipeline.

Prior to the development of the 64bit port, “Slackware ARM” also referred to the 32bit version of the Slackware Operating System.

“Slackware ARM” is the umbrella project name for all Slackware activities on the ARM platform.

Slackware AArch64 / ARM 64bit

“AArch64” is ARM's marketing name for their 64bit platform. In the user space the platform is 'aarch64' and 'arm64' within the Linux Kernel. The names are synonymous.

"Committed" / Definitley-going-to-be-done

Category Enhancement More Owner ETA (+When it's ready)
Hardware Model Support Support HoneyComb LX2 Manufacturer page mralk3@slackware 2023 some time
Tutorial/Doc Complete document The Direct integration guide needs to be completed to enable the community to understand how to contribute Hardware Model support. A video will also be made to walk through it mozes@slackware Late 2023
All In One Installers Create bootable USB AiOs for x86/64 Continue hacking on tool mozes@ May 2023

Boot - OS Initial RAM disk os-initrd-mgr: Package only the Kernel modules required for the local environment. The generic OS InitRD contains the vast majority of Kernel modules in order to be able to support new Hardware Models. This inflates the InitRD by hundreds of MBs, delaying the booting of the OS. The kernel package will continue to ship a full-fat OS InitRD, and os-initrd-mgr will slim it down during the package post installation. If unable to collect the Kernel modules, os-initrd-mgr will preserve the previous set of Kernel modules. os-initrd-mgr will also be called from within the Installer, so the new OS has a trimmed initrd. May 2022
Tutorial/Doc Create a wiki doc and short video explaining how to use the Slackware ARM build system. There's a doc already in source/README.txt. This enables people to easily modify the Slackware Kernel and any packages required for their Hardware Model July 2022
pre-boot shell (slkpbs) stage 0 pre-script load n/a Insert a new first stage shell prior to the Kernel Module Loader scripts being executed. This enables them to be hacked upon which may make onboarding new HWMs easier. Dec 2022
All In One Installers Release and migrate Migrate to new AiO installers. Needs script work to modify paths and mask out the bare installers imgs, and update install guides. mozes@ Jan 2023
All In One Installers Upstream AiO for x86 Patch probe with filter code, write converter script for x86. Test and upstream mozes@ Jan 2023
Video support VC4 Video support for RPi4 Seems stable with Linux 6.1 mralk3, mozes Jan 2023

"Exploring" (Thinking About It)

Idea / Category Priority Further information Owner
have a/kernel-firmware package trigger an initrd rebuild. Low This is to capture any new firmware for their Hardware Model. However, the HWM firmware changes rarely, and if anybody really wants the OS InitRD to receive new firmware, they can run os-initrd-mgr. mozes@slackware
RK3399 U-Boot (SPI) flashing tool within the OS Low (it's not ancitipated that a new release of U-Boot for Slackware will be frequent). Productised version of this tool. Add a new package a/hwm-bw-rk3399, have it ship new and previous fw in /usr/share with command line options to flash either one. Wanted to couple this with slackpkg so that an 'update your spi flash' message could be delivered. I don't think this is an appropriate candidate for automation - it always needs user confirmation. mozes@slackware
Switch OSinitrd to use LZMA compression n/a os-initrd-mgr supports decompression of gzip and LZMA, but presently compresses with gzip. LZMA reduces size of initrd by ~10MB, but compression time is approx 4 mins compared to 1 minute for gzip; so increases time taken for kernel package upgrades and using os-initrd-mgr directly. kernel.SlackBuild would also need modifying to initially compress it. Unsure if it's worth the bother for the half second more it takes to load 10more MB. mozes@slackware
Hardware Model Support Slacking Support Pine64 PinePhone mralk3@slackware
Installer: Offer to upgrade the EEPROM firmware on RPi - It'd be a post installation script that checks if the relevant 2 packages are installed, validates if upgrade is available and offers. Not really sure it's worth it though as it'll always become out of date at some point - esp for a stable release.. mozes
Tutorial/Doc Non A-i-O Installation guides Take the previous HTTP and USB installation guides and link to them from the AiO guides, should people prefer to use the bare installer. No priority

Slackware ARM / 32bit

32bit Slackware ARM development ended with the release of Slackware 15.0.

Slackware ARM 32bit 15.0 is maintained with security fixes and other minor enhancements, however.
