Re: [Upstream] Re: [PATCH v3] arm64: dts: freescale: imx93-phycore-som: Delay the phy reset by a gpio

Hello Shawn,

sorry for bothering.

Can you tell me if there's anything missing or wrong with this patch,
or if there's anything else I can do so that it becomes applied?

Thanks and regards,
Christoph

I agree it is long enough, but i'm also surprised how slow
the
kernel
was. Are you using a fixed IP address, or dhcp?

I use a fixed IP address.

But isn't the bringup of ethernet+phy interface one of the last
things
that happens during the kernel boot-up?

Mounting the rootfs is somewhat towards the end of the core
kernel. But if you have an initramfs, there can be modules loaded
both
before and afterwards, and once the rootfs has been mounted, yet
more
modules can be loaded.

However, what timing would you expect?

I've seen interfaces configured up from deep within
register_netdev(). I don't remember the exact configuration, but
i
thought it was NFS root. It might be in combination with
initramfs.
If
you have the Ethernet driver as a module in the initramfs, and
are
using the "rootwait" option, it could be that you are already
past
the
point it would first mount the rootfs, and with every new device
popping into existence it is trying to see if the just created
device
allows it to do the mount. At that point, register_netdev() is
going
to trigger actions.
