@ -795,6 +795,24 @@ It is recommended to use this API instead of the KVM_SET_MEMORY_REGION ioctl.

The KVM_SET_MEMORY_REGION does not allow fine grained control over memory
|

allocation and is deprecated.

4.35 KVM_SET_TSS_ADDR
|
||||
|
||||
Capability: KVM_CAP_SET_TSS_ADDR
|
||||
Architectures: x86
|
||||
Type: vm ioctl
|
||||
Parameters: unsigned long tss_address (in)
|
||||
Returns: 0 on success, -1 on error
|
||||
|
||||
This ioctl defines the physical address of a three-page region in the guest
|
||||
physical address space. The region must be within the first 4GB of the
|
||||
guest physical address space and must not conflict with any memory slot
|
||||
or any mmio address. The guest may malfunction if it accesses this memory
|
||||
region.
|
||||
|
||||
This ioctl is required on Intel-based hosts. This is needed on Intel hardware
|
||||
because of a quirk in the virtualization implementation (see the internals
|
||||
documentation when it pops into existence).
