Parameters: what parameters are accepted by the capability.

are not detailed, but errors with specific meanings are.

7.1 KVM_CAP_PPC_ENABLE_HCALL
|
||||
|
||||
Architectures: ppc
|
||||
Parameters: args[0] is the sPAPR hcall number
|
||||
args[1] is 0 to disable, 1 to enable in-kernel handling
|
||||
|
||||
This capability controls whether individual sPAPR hypercalls (hcalls)
|
||||
get handled by the kernel or not. Enabling or disabling in-kernel
|
||||
handling of an hcall is effective across the VM. On creation, an
|
||||
initial set of hcalls are enabled for in-kernel handling, which
|
||||
consists of those hcalls for which in-kernel handlers were implemented
|
||||
before this capability was implemented. If disabled, the kernel will
|
||||
not to attempt to handle the hcall, but will always exit to userspace
|
||||
to handle it. Note that it may not make sense to enable some and
|
||||
disable others of a group of related hcalls, but KVM does not prevent
|
||||
userspace from doing that.
|
||||
|
||||
If the hcall number specified is not one that has an in-kernel
|
||||
implementation, the KVM_ENABLE_CAP ioctl will fail with an EINVAL
|
||||
error.
