      target-ppc: disable unsupported modes for SPR_CTRL/SPR_UCTRL · 4e381819
      由 Alexey Kardashevskiy 提交于 
      The Figure 17 "SPR encodings" of the PowerISA 2.07 describes CTRL SPR as:

                       priviledged
#   spr5-9 spr0-4 name mtspr mfspr len cat
136 00100  01000  CTRL   -    no    32  S
152 00100  11000  CTRL  yes    -    32  S

According to this chart, the hypervisor's CTRL (#152) does not support
reading, the user-space's CTRL (UCTRL, #136) does not support writing.

This replaces unsupported operations with the default SPR_NOACCESS hook.

      spapr_vscsi: Fix REPORT_LUNS handling · 3052f0d5
      由 Nathan Whitehorn 提交于 
      Intercept REPORT_LUNS commands addressed either to SRP LUN 0 or the well-known
LUN for REPORT_LUNS commands. This is required to implement the SAM and SPC
specifications.

Since SRP implements only a single SCSI target port per connection, the SRP
target is required to report all available LUNs in response to a REPORT_LUNS
command addressed either to LUN 0 or the well-known LUN. Instead, QEMU was
forwarding such requests to the first QEMU SCSI target, with the result that
initiators that relied on this feature would only see LUNs on the first QEMU
SCSI target.

Behavior for REPORT_LUNS commands addressed to any other LUN is not specified
by the standard and so is left unchanged. This preserves behavior under Linux
and SLOF, which enumerate possible LUNs by hand and so address no commands
either to LUN 0 or the well-known REPORT_LUNS LUN.

      spapr-pci: enable adding PHB via -device · 09aa9a52
      由 Alexey Kardashevskiy 提交于 
      Recent changes introduced cannot_instantiate_with_device_add_yet
and removed capability of adding yet another PCI host bridge via
command line for SPAPR platform (POWERPC64 server).

This brings the capability back and puts SPAPR PHB into "bridge"
category.

This is not much use for emulated PHB but it is absolutely required
for VFIO as we put an IOMMU group onto a separate PHB on SPAPR.

      PPC: KVM: fix "set one register" · 7a7c05d7
      由 Alexey Kardashevskiy 提交于 
      Due to missing @one_reg_id assignment in _spr_register(),
the kvm_get_one_reg/kvm_set_one_reg API has never really been working.

This reenables the API by assigning the @one_reg_id field in the SPR
descriptor.

      mmu-hash64: fix Virtual Page Class Key Protection · 363248e8
      由 Cédric Le Goater 提交于 
      commit f80872e2 (mmu-hash64: Implement
Virtual Page Class Key Protection) added a new page protection
mechanism based on page keys and the AMR register to control access.

The AMR register allows or prohibits reads and/or writes on a page
depending on the control bits associated to the key. A store or a load
is only permitted if the associate bit is 0 (Power ISA), and not 1 as
the code is currently doing. This patch modifies ppc_hash64_amr_prot()
to correct the protection check.

This issue was unvailed by commit ccfb53ed6360cac0d5f6f7915ca9ae7eed866412
(target-ppc: fix Authority Mask Register init value) which changed the
initialisation value of the AMR register to 0.

      target-ppc: fix Authority Mask Register init value · 0dc083fe
      由 Alexey Kardashevskiy 提交于 
      The existing default value (-1) of the AMR register forbids data access
to all 32 classes. Since the guest linux does not change this register,
we end up with the guest hanging right after switching from the real to
protected mode.

This sets the default AMR value to zero what enables data access for all
classes.

The only reason for not hitting this bug before is that
kvm_arch_put_registers() did not put any SPR to KVM due to missing
assignment of @one_reg_id in _spr_register() (which is going to be fixed
by a separate patch).

      KVM: Split QEMUMachine typedef into separate header · 9c06a1f7
      由 Alexander Graf 提交于 
      Older gcc versions (such as the one in SLES11) get confused when you declare
a typedef on the same struct twice.

To work around that limitation, let's extract the QEMUMachine typedef into a
separate header file that is guarded by preprocessor duplicate include checks.

This fixes the following type of compile errors for me:

  In file included from vl.c:125:
