+  * Post-setup changes required to select which one user should boot
+    * i.e., change initramfs / kernel lines to -v8 in config.txt / config-kernel.txt
+    * https://chat.rockylinux.org/rocky-linux/pl/e7h9sqcb4pdnpqpwah3wcjxjac
+* Neil and Sherif spoke to risc-v folks at FOSDEM/SOOCon24
+  * No exact timeline, but hoping to get leads on hardware to use
+
+## Open Floor
+
+* Stack: the wiki looks abandoned because the index page is empty/stubbed
+
+## Action Items
+
+* Follow up on Orange Pi5
+* Follow up on Libre boards
+* Create variant for 16k kernel
+* Kernel Packer for altarch
+* Actually put content on wiki index/landing page so it doesn't look abandoned

+# SIG/AltArch meeting 2024-02-23
+
+## Attendees
+
+* Neil Hanlon
+* Sherif Nagy
+* Brian Clemens
+* Stack
+* Alan Sill
+
+## Follow Ups
+
+* SBC Support - We're close on a lot of the boards we aim to support (Orange Pi, Libre boards, Rock Pro, RPi5, etc)
+  * Raspberry Pi5
+    * Needs 16k kernel variant
+* arm-trusted-firmware in staging for 8 and 9
+  * please test, adds support for some SBCs we target
+* RISC-V - Communications ongoing with RISC-V foundation for firmware
+  * What else do we want aside from what they may be able to give us?
+
+## Open Floor
+
+* Alan has Turing Pi boards to run his Pis--would be nice to be able to test these
+  * Jeff Geerling did a video recently on Turing Pi cluster board
+  * "little clusters" -- just shared NFS, works ok. needs to be NVME because of i/o thrashing, though
+* Stack: there has been a lot of interest in SBCs in Rocky the past few months
+  * Would be good to have a plan to convert interested parties to contributors
+    * we have a lot of SBC $$$ to spend on HW for folks
+  * Roadmap & Status -- What do we support, who supports it, what works/doesn't work
+  * https://git.resf.org/testing/SBC-progress-tracking
+* Risc-V
+  * Alan has [Lichee Pi 4a](https://wiki.sipeed.com/hardware/en/lichee/th1520/lc4a/lc4a.html) | https://sipeed.com/licheepi4a
+* Should we include non-altarch (x86_64) SBCs in our list of what works?
+  * They work out of the box (for the most part), so, let's just include them
+  * https://radxa.com/products/x/x2l/#techspec - GPIO via a Pico
+    * Alan wants to get this running under Rocky at some point
+      * also looking at https://www.mixtile.com/cluster-box/
+* Stack: Grace Hopper?
+  * seems to be only debian from NVidia
+  * Brian: Yoshi (CIQ) may have a contact that knows more information about Grace Hopper and Rocky
+* Sherif: Intel GPU update
+  * Met with them through HPC SIG (Jeremy)
+  * DKMS version first for testing
+  * Later: signed for secureboot and installable as kmod package (kernel SIG)
+    * User tools in HPC SIG
+  * NVIDIA -- maybe we can talk to them after we show this working well, collaborate
+    * Needs legal review and sign-off from NVIDIA
+    * many questions about this... e.g. How can we trust signing a proprietary blob for SB signing?
+* Stack's SBC tower: https://52pi.com/products/52pi-rack-tower-acrylic-cluster-case-for-raspberry-pi-12-layer?_pos=21&_sid=39b8f5ea0&_ss=r
+
+## Action Items
+
+* Neil to reach out to Equinix regarding arm hw for altarch
+* Neil to reply to RV folks
+* Neil to look into wiki content population
+* Neil to file ticket to investigate kernel packer to repack upstream RPi kernel
+* Neil to work on SBC Kernel variant config in KernelPacker
+* Sherif to work on Raspberry Pi kernel variants
+
