There is a script that I use, /usr/local/firmware/extract-fw-all. I copy the script to a working area, then download latest firmware from https://gitlab.com/kernel-firmware/linux-firmware, then:

# tar -xf linux-firmware-main.tar.gz
# sync
# cp -a -f --remove-destination linux-firmware-main/* /usr/lib/firmware/
# sync
# ./extract-fw-all

# mkdir -p firmware_linux_all_k6p12-20250128/usr/lib
# cp -a fnd-firmware/lib/firmware firmware_linux_all_k6p12-20250128/usr/lib/

took out some big firmware, to firmware_linux_extra_k6p12-20250128

# dir2pet firmware_linux_all_k6p12-20250128

The PET is 110MB, very big. The previous one, used in Easy Scarthgap and Daedalus, is 103MB.

Hopeful fix fstrim on USB SSD

January 28, 2025 — BarryK

I posted about compiling the kernel 6.12.11 with change to hopefully support TRIM over USB:

Kernel 6.12.11 compiled on Easy Scarthgap — January 28, 2025

...there is also a link to forum discussion.

After more reading, I have devised code in the 'init' script in the initrd, that intends to detect if a USB SSD supports TRIM, then enables usage of fstrim. This is the modified code:

###execute TRIM on ssd###
TRIMflg=''
if [ "$WKG_FS" == "ext4" ];then #200302  200621 now have full hdparm.
 #20250127 discard_granularity test not work 6.12.x kernel...
 #TESTdiscard="$(cat /sys/block/${WKG_DRV}/queue/discard_granularity 2>/dev/null)"
 TESTdiscard="$(cat /sys/block/${WKG_DRV}/queue/discard_max_bytes 2>/dev/null)"
 if [ -n "$TESTdiscard" ];then
  if [ "$TESTdiscard" != "0" ];then
   TRIMflg='1'
  fi
 fi
 #20250128 hdparm detect and CONFIG_USB_UAS kernel now maybe can run fstrim...
 if [ "$TESTdiscard" == "0" ];then
  hdparm -I /dev/${WKG_DRV} | grep 'Data Set Management TRIM supported'
  if [ $? -eq 0 ];then
   #fstrim may still not work, depends if usb interface supports usb-attached-scsi
   #ref: https://askubuntu.com/questions/860618/fstrim-on-external-ssd-drives-dont-work
   #ref: https://www.jeffgeerling.com/blog/2020/enabling-trim-on-external-ssd-on-raspberry-pi
   #figuring out my own method, this matches scsi number to drive:
   T1="$(ls -d -1 /sys/bus/scsi/drivers/sd/*/block/${WKG_DRV} | head -n 1)"
   #ex: /sys/bus/scsi/drivers/sd/6:0:0:0/block/sdb
   if [ -n "$T1" ];then
    T2="$(echo -n "$T1" | rev | cut -f 3 -d '/' | rev)" #ex: 6:0:0:0
    T3="$(find /sys/devices/ -path "*/scsi_disk/${T2}/*" -name provisioning_mode)"
    #ex: /sys/devices/pci0000:00/0000:00:14.0/usb2/2-4/2-4:1.0/host6/target6:0:0/6:0:0:0/scsi_disk/6:0:0:0/provisioning_mode
    if [ -n "$T3" ];then
     T4="$(cat "$T3")"
     if [ "$T4" == "full" ];then
      echo unmap > $T3
      #ex: this changes /sys/block/sdb/queue/discard_max_bytes from 0 to 4294966784
     fi
     #test again...
     TESTdiscard="$(cat /sys/block/${WKG_DRV}/queue/discard_max_bytes 2>/dev/null)"
     if [ "$TESTdiscard" != "0" ];then
      TRIMflg='1'
     fi
    fi
   fi
  fi
 fi
fi
export TRIMflg #read in /sbin/fscheck

Now, if the USB interface supports USB-attached-SCSI-protocol (UASP), then hopefully fstrim will work after doing the above.

Kernel 6.12.11 compiled on Easy Scarthgap

January 28, 2025 — BarryK

Easy Scarthgap 6.5.6 has the 6.12.10 kernel. I have compiled 6.12.11, making these two changes (bold):

# USB Host Controller Drivers
#
CONFIG_USB_C67X00_HCD=y
CONFIG_USB_XHCI_HCD=y
# CONFIG_USB_XHCI_DBGCAP is not set
CONFIG_USB_XHCI_PCI=y
CONFIG_USB_XHCI_PCI_RENESAS=y


# NOTE: USB_STORAGE depends on SCSI but BLK_DEV_SD may
# also be needed; see USB_STORAGE Help for more info
#
CONFIG_USB_STORAGE=y
# CONFIG_USB_STORAGE_DEBUG is not set
CONFIG_USB_STORAGE_REALTEK=y
CONFIG_REALTEK_AUTOPM=y
CONFIG_USB_STORAGE_DATAFAB=y
CONFIG_USB_STORAGE_FREECOM=y
CONFIG_USB_STORAGE_ISD200=y
CONFIG_USB_STORAGE_USBAT=y
CONFIG_USB_STORAGE_SDDR09=y
CONFIG_USB_STORAGE_SDDR55=y
CONFIG_USB_STORAGE_JUMPSHOT=y
CONFIG_USB_STORAGE_ALAUDA=y
CONFIG_USB_STORAGE_ONETOUCH=m
CONFIG_USB_STORAGE_KARMA=m
CONFIG_USB_STORAGE_CYPRESS_ATACB=y
CONFIG_USB_STORAGE_ENE_UB6250=y
CONFIG_USB_UAS=y

The first change was due to I read somewhere that a USB3 interface, with a Renesas chip, was being treated as USB2 only, and enabling this fixed it.

The second change is in response to discussion here:

https://forum.puppylinux.com/viewtopic.php?t=13709

...but I still don't know how that helps to detect if a USB SSD supports trim.

I recently compiled 6.12.10 kernel for Easy Daedalus, see blog post:

Linux kernel 6.12.10 compiled in Easy Daedalus — January 24, 2025

...and will leave it at that.

OpenEmbedded Scarthgap revision-4 compile

January 27, 2025 — BarryK

This is a complete recompile in my fork of OpenEmbedded/Yocto of the packages used to build EasyOS Scarthgap-series. This is based upon OE/Yocto release 5.0.6:

https://wiki.yoctoproject.org/wiki/Releases

Which I have named "revision-4", and all the binary packages have "-r4" in their name, for example "acpid-2.0.34-r4-nocona-64.tar.xz". The current release of EasyOS, 6.5.6, is built with "revision-3" build in OE, which is based on the Yocto 5.0.4 release. Here are the package version changes r3 to r4:

chromium-x11     131.0.6778.85 131.0.6778.139
expat            2.6.3         2.6.4

libstd-rs        1.75.0        1.80.1

systemd-boot     255.4         255.13
tzdata           2024a         2024b
vim              9.1.0698      9.1.0764
xserver-xorg     21.1.13       21.1.14

Chromium needs special mention, as we were stuck, the Chromium developers upped the minimum required rust version from 1.75 to 1.80. The OE/Yocto Scarthgap release only has the former. The guys though, have a way around this, with something called a "meta-lts-mixins" layer, see here:

https://git.yoctoproject.org/meta-lts-mixins

...what that means practically, is that this has backported rust 1.80.1 to Scarthgap. See my post here:

Fix for version depth limit

January 25, 2025 — BarryK

Alfons discovered a little bug. He sent me a snapshot of Easy Version Control (in the Filesystem menu), showing that the depth-limit is 5, yet there are now 6 versions. In other words, when he updated to Scarthgap 6.5.6, it was the 6th, so the oldest version, 6.4.4, should have been deleted.

The cause was that /var/local/version-history-depth did not exist. This is read by the 'init' script in the initrd, but if the file doesn't exist then depth calculation will be messed up.

File /var/local/version-history-depth only gets created when Easy Version Control is run, and it looks like Alfons had never run it before. And of course the session has to be saved after running Easy Version Control.

I fixed it in the 'init' script by creating it if it doesn't exist, and assigning a default of "5".
