Should there be a new post "Moving to kernel 5.5"?
Probably not until after Chrimbo.
It'll also need to be on the BRANCH=next at https://github.com/hexxeh/rpi-firmware to avoid surprising the casual users of rpi-update.

Wondering why 4.19 is till been worked on?
Because all the end user RPi kernel bases on the last LTS release, which is reliable.

That post looks like 5.5 for Pi4's will be very mainstream.

Should there be a new post "Moving to kernel 5.5"?
The Mainline 5.5 has only very little Pi4 support from a user perspective (No PCIe, USB, thermal or V3D support). Btw 5.5 is no LTS release.

There is USB keyboard and mouse in 5.3 Ubuntu, so they needed to tweak that?
PCIe is Ethernet?
Ubuntu reported Mesa 19.2 which is V3D aware.

LTS is not an issue for me, change does not scare me, I embrace digital disruption ;)
If I keep repeating it, I start to believe it :lol:
I guess it depends on the user and their requirements.

Probably lots of tiny details I don't know about, but mainstream does seem a bit closer to usable.
I guess I still need to learn more about what the Gentoo people like Sakaki/Roy and others and Canonical did to get their OS distributions to work.
I have been finding Buildroot is useful for learning the kernel basics.
I tried changing kernels in that and crashed and burned.

AFAIK Ubuntu and Gentoo doesn't use the mainline kernel. They still use the RPi vendor kernel or a fork. The distributions i'm aware of that use the mainline kernel are Arch (arm64 variant), Debian, OpenSuSE and Fedora.

The chances are good that Linux 5.5 will gain GENET support (Ethernet) for RPi4. PCIe is PCI express and a requirement for USB XHCI.

read config file,

Code: Select all

# CONFIG_ZSWAP is not set
# CONFIG_ZPOOL is not set
# CONFIG_ZBUD is not set
can we have it enable?

I'll let you know, my main rig is Arch testing, currently at 5.4.3, so getting close to 5.5
