The test selects between two identical values, so it doesn't look useful.
It turns out that the tested expression can only be true anyway, so drop
the test, the corresponding parameter, and the corresponding argument at
the only call site.

I have fixed few major issue. Could you perform boot
System call table generation script must be run to gener-
ate unistd_32/64.h and syscall_table_32/64/c32/spu.h files.
This patch will have changes which will invokes the script.

PowerPC uses a syscall table with native and compat calls
interleaved, which is a slightly simpler way to define two
matching tables.
As we move to having the tables generated, that advantage
is no longer important, but the interleaved table gets in
the way of using the same scripts as on the

Previously when a device was being emulated by an L1 guest for an L2
guest, that device couldn't then be passed through to an L3 guest. This
was because the L1 guest had no method for accessing L3 memory.
The hcall H_COPY_TOFROM_GUEST provides this access. Thus this setup for
passthrough can now
A guest cannot access quadrants 1 or 2 as this would result in an
exception. Thus introduce the hcall H_COPY_TOFROM_GUEST to be used by a
guest when it wants to perform an access to quadrants 1 or 2, for
example when it wants to access memory for one of its nested guests.
Also provide an
Allow for a device which is being emulated at L0 (the host) for an L1
guest to be passed through to a nested (L2) guest.
The existing kvmppc_hv_emulate_mmio function can be used here. The main
challenge is that for a load the result must be stored into the L2 gpr,
not an L1 gpr as would normally
The functions kvmppc_st and kvmppc_ld are used to access guest memory
from the host using a guest effective address. They do so by translating
through the process table to obtain a guest real address and then using
kvm_read_guest or kvm_write_guest to make the access with the guest real
address.
The kvmppc_ops struct is used to store function pointers to kvm
implementation specific functions.
Introduce two new functions load_from_eaddr and store_to_eaddr to be
used to load from and store to a guest effective address respectively.
Also implement these for the kvm-hv module. If we are
The POWER9 radix mmu has the concept of quadrants. The quadrant number
is the two high bits of the effective address and determines the fully
qualified address to be used for the translation. The fully qualified
address consists of the effective lpid, the effective pid and the
effective address.
There exists a function kvm_is_radix() which is used to determine if a
kvm instance is using the radix mmu. However this only applies to the
first level (L1) guest. Add a function kvmhv_vcpu_is_radix() which can
be used to determine if the current execution context of the vcpu is

The kvm capability KVM_CAP_SPAPR_TCE_VFIO is used to indicate the

Thus make this capability dependent on having the cpu feature
When booting a kvm-pr guest on a POWER9 machine the following message is
observed:

This is because the guest is expecting to be able to use 1T segments
however we don't indicate support for it. This is because we don't
