...the basic platform support and the UART blacklisting. The series has also grown a constcorrectness fix for the other existing platforms too. Still no SATA support from upstream sadly. Bamvor has written some generic docs at http://wiki.xenproject.org/wiki/Xen_ARMv7_with_Virtualization_Extensions/Allwinner Thanks, Ian.

...ich use a custom usb protocol and usb redirection over the network for qemu. And although not the original author I'm now a days a maintainer of libusb, usb-3 bulk streams support in the xhci driver, the uas driver, and libahci_platform. In my spare time I work on u-boot and Linux support for Allwinner ARM SoCs, I'm a u-boot maintainer for these, and maintain the sata, mmc and usb kernel drivers. About a year ago I joined the Red Hat graphics team, where my first task was to help to get libinput up to a level where it could be used as the input stack for Wayland. The work on this is windin...

See http://www.gossamer-threads.com/lists/xen/devel/297170 for some information on how to get this going. I''ve rebased and addressed the review comments. With this rebase I''ve picked up some patches from Julien which were required to do things properly, so the gic v7 and device blacklisting patches have been changed to use the proper mechanisms. Previously I was able to boot

Goodmorning, I''m currently playing with XEN/arm on my Allwinner A20 (cubieboard2) I would like to get the XENFB driver working on domU. But currently in xen/arm there''s no support for VFB, atleast qemu is not supported. But this video http://www.youtube.com/watch?v=po1IeElg8tg and this one http://www.youtube.com/watch?v=Km6gBnIqaWo is showing a worki...

See http://www.gossamer-threads.com/lists/xen/devel/297170 for some information on how to get this going. I''ve rebased and addressed the review comments. As before several of the patches are not to be applied because they can be done better using infrastructure from Julien''s "Allow Xen to boot with a raw Device Tree" patch. They are included for completeness. With

...committed to ARM platforms for the power savings. At this point I don't know at all about the performance. I AM running my mailserver (Redsleeve6/Postfix/mysql/spammassasin/clamav/amavis) on a Cubietruck and it seems to be handling my mail load. The Cubieboard2 and Cubietruck both use the Allwinner A20 (1Gb mem/100Mb lan vs 2Gb mem/1Gb lan). Both have sata. The Wandboard quad is $40 more than the CT, but a quad cpu (vs duo). A number of linuxes are available for the various armv7 boards. The armv8s (64bit) are now coming out, but still pricey for my budget. But going from 70-90w wit...
