is nice and pretty and I would like to get it working as a NAS. If
not, I will stay with the Cubies. If they get far enough into the
uboot and kernel work by Hans, he has a nice multiport sata card
working for the Cubietruck, so I can go all sata, and not usb
drives
for my NAS. (This support is in F22, not F21). Hans ALMOST has the
CUbietruck internal WiFi working in the F23 alpha (kernel patches
needed), and will have it upstream 'soon', but don't hold your
breath
for the internal bluetooth. (see his projects page:
https://revspace.nl/KernelDriverProjects).
I think you need to stop bundling kernel work you speak of with
Fedora release numbers, the two aren't really related. There is
nothing stopping you from using the kernel with those features
(e.g. from F23a) on RSEL6 (F12 based) or RSEL7 (F19 based) and
having the hardware work on those.
If I do a RSEL7 for Cubies, I will indeed do that. That is use the
current F23a uboot and kernel (4.2.0-0.RC6) as it has all the
upstream work that Hans has provided (and more coming). But for the
pogoplug, the F18 remix has the most current kernel available to me
(3.8.7-201).
Indeed, that sounds right, since F18 was the last soft-float (i.e.
ARMv5)
release of Fedora. F19 and later are hard-float (ARMv7) only.
First I recall hearing 'soft-float' and 'hard-float'. What do those
terms mean (where can I read more?).
ARMv6 and earlier had no mandatory FPU support. I may be wrong,
but IIRC, ARMv5 and earlier had no optional FPU support, either.
On ARMv6 FPU support was optional (and R-Pi, for example, is
ARMv6 with a hardware FPU).
With ARMv7 and later, FPU is mandatory.
Soft-float / hard-float refers to how the FPU operands are passed.
In case of hard-float they are passed directly via the FPU
registers.
Here is a reasonably good summary on the subject:
