[Xen-devel] [HACKATHON 2016] ARM Status

[Apologies for the late send]

Xen - ARM Status
There was discussion on the following items:

*) Booting Xen on 64-bit ARM SoC
  o) Unfortunately Xen was executed in EL1.
  o) Advice was given that the firmware should boot the Xen in EL2.
  o) The ARMv7 secure mode switch to Hyp trick is not valid on AArch64.

*) ARMv7 Cubietruck bringup was also discussed
  o) One pain point mentioned was debugging the DomU guest
  o) There are no debug capabilities for a Xen guest, but
  o) There are a set of hyp calls that can be placed in the guest to
     aid with debugging.
  o) The documentation on these hyp calls needs refreshing in a wiki
  o) Details of these can be found at: xen/arch/arm/traps.c

*) There is no list of names/ownership for HW platforms
  o) This is due to it being non-trivial to deduce a name from wiki
  o) If people care about a board, they should make themselves known.
