[Xen-devel] [PATCH 0/2] Handle SMCs and HVCs in conformance with SMCCC

[Volodymyr Babchuk <volodymyr_babchuk@xxxxxxxx>]

Hello all,

This patch series adds a generic way to handle standard calls
that are defined in ARM SMC calling convention (SMCCC).

First patch adds generic handler and second one moves PSCI
handling code to that generic handler.

With this patch series guest can query hypervisor in a standard
way to determine which virtualization system is used.
The same applies to PSCI calls. Now guest can tell if PSCI calls
are handled by hypervisor or by, say, ARM TF.

Also those patches are needed for upcoming TEE support.

It was tested on RCAR H3 Platform.
