Introduce HYPERVISOR_suspend() and a few additional empty stubs for Xen arch specific functions called by drivers/xen/manage.c. Signed-off-by: Stefano Stabellini Signed-off-by: David Vrabel

arm: xen: implement multicall hypercall support.

2014-04-24T12:09:46+00:00

As part of this make the usual change to xen_ulong_t in place of unsigned long. This change has no impact on x86. The Linux definition of struct multicall_entry.result differs from the Xen definition, I think for good reasons, and used a long rather than an unsigned long. Therefore introduce a xen_long_t, which is a long on x86 architectures and a signed 64-bit integer on ARM. Use uint32_t nr_calls on x86 for consistency with the ARM definition. Build tested on amd64 and i386 builds. Runtime tested on ARM. Signed-off-by: Ian Campbell Cc: Stefano Stabellini Cc: Konrad Rzeszutek Wilk Cc: Boris Ostrovsky Signed-off-by: David Vrabel

xen/arm: hypercalls

2012-09-14T13:33:21+00:00

Use r12 to pass the hypercall number to the hypervisor. We need a register to pass the hypercall number because we might not know it at compile time and HVC only takes an immediate argument. Among the available registers r12 seems to be the best choice because it is defined as "intra-procedure call scratch register". Use the ISS to pass an hypervisor specific tag. Changes in v2: - define an HYPERCALL macro for 5 arguments hypercall wrappers, even if at the moment is unused; - use ldm instead of pop; - fix up comments.
