[Xen-devel] [PATCH 0/3] Separate the functions of the memory_mapping and iomem_permission DOMCTLs

[Arianna Avanzini <avanzini.arianna@xxxxxxxxx>]

Hello,

this patchset originates from the twelfth version of the series "Implement the
XEN_DOMCTL_memory_mapping hypercall for ARM" ([1]). It includes only the last
three patches, whose aim was to separate the functions of the memory_mapping
and iomem_permission DOMCTLs. The memory_mapping DOMCTL's behavior, in fact,
currently defaults to implicitly granting to a domain access permission to an
I/O-memory range that was to be mapped in its guest address space, while a
specific hypercall for granting access permissions to I/O-memory ranges exists.

With respect to v12 of the original patchset, the main change concerns the use
of libxl_defbool_val() to access the value of the gfx_passthru configuration
option, as indicated by Ian Campbell. Also, the description of commit 0002 has
been fixed in its lack of clarity pointed out by Ian Campbell.

The patches have been tested on a cubieboard2, with Linux v3.15 as a dom0
and both ERIKA Enterprise ([2]) and Linux v3.15 as a domU. It has also been
tested on an x86_64 machine with Linux v3.15 as both dom0 and domU.

Any feedback is, as usual, welcome.
Thank you,
Arianna
