there's no difference on modern hardware. (Note I didn't verify this.)
Judging by a google search for "qreal" "float" "arm" this difference
causes endless problems. I even found a Fedora build bug related to it.
However it's a matter for upstream to fix it. Not something we could
carry around only in Fedora IMHO.

virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
I need to replace my Lenovo x120e duo core Fedora (F17 still) notebook
soon; I am getting USB errors...
So can I get a comparable arm notebook to get better battery etc and put
F19 on it? And will I get enough apps (I really only need fairly
'basic' 'office' apps) at this time. Oh and 'cheap' (< $400), 200+Gb,
and keyboard is manditory :)
I was pointed to the Asus TF700T, but it is only a 10" display.
My search fu is typically weak, and I have not found a list of systems
to evaluate that I could consider.
So I got myself a second mirabox and figured I'd try to get F19 on there.
I got myself a microSD card as well, and wrote the image on there. When
into the mirabox, I can see the SD card from linux and mount the
But after that I seem to be stuck. The instructions on
seem to stop after the "write the image" step and don't have any
actually booting from the SD card.
I figured I'd just try to manually load kernel/initramfs from the card,
but I seem
to have issues accessing it from U-boot:
Card did not respond to voltage select!
Manufacturer ID: ff
Tran Speed: -1
Rd Block Len: -1
SD version 15.15
High Capacity: Yes
Bus Width: 1-bit
I'm also not sure which kernel version to point to. From the config file
it seems like
the supplied kernels do have CONFIG_ARM_APPENDED_DTB set to y; can I
together uImage-3.9.5-301.fc19.armv7hl and the DTB, or do I need to add
to vmlinuz and then convert to uImage?
U-boot version on the mirabox is
U-Boot 2009.08 (Sep 16 2012 - 22:50:06)Marvell version: 1.1.2 NQ
If I can find some time later today I might try putting the image on a
USB stick and
booting from that instead of the SD card, but that's not something I'd
want to keep
as a permanent solution.
Idea anyone ?
