powerpc/mm: Update the WIMG check during H_ENTER
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
On powerpc, we must only signal huge page support to the guest if
all memory areas are capable of supporting huge pages. The commit
2d103aae87 ("fix hugepage support when using memory-backend-file")
already fixed the case when the user specified the mem-path property
for NUMA memory nodes instead of using the global "-mem-path" option.
However, there is one more case where it currently can go wrong.
When specifying additional memory DIMMs without using NUMA, e.g.
qemu-system-ppc64 -enable-kvm ... -m 1G,slots=2,maxmem=2G \
-device pc-dimm,id=dimm-mem1,memdev=mem1 -object \
memory-backend-file,policy=default,mem-path=/...,size=1G,id=mem1
the code in getrampagesize() currently assumes that huge pages
are possible since they are enabled for the mem1 object. But
since the main RAM is not backed by a huge page filesystem,
the guest Linux kernel then crashes very quickly after being
started. So in case the we've got "normal" memory without NUMA
and without the global "-mem-path" option, we must not announce
huge pages to the guest. Since this is likely a mis-configuration
by the user, also spill out a message in this case.

Recent server processors use the Hypervisor Emulation Assistance
interrupt for illegal instructions and *some* type of SPR accesses.
Also the code was always generating inval instructions even for priv
violations due to setting the wrong flags
Finally, the checking for PR/HV was open coded everywhere.
This reworks it all, using little helper macros for checking, and
adding the HV interrupt (which gets converted back to program check
in the slow path of excp_helper.c on CPUs that don't want it).

Under some circumstances, we need to direct ISI and DSI interrupts
at the hypervisor, turning them into HISI/HDSI, and using different
SPRs (HDSISR and HDAR) depending on the combination of MSR_DR and
the corresponding VPM bits in LPCR.
This moves part of the code into helpers that are fixed to select
the right exception type and registers. On pre-P7 processors, LPCR
is 0 which provides the old behaviour of directing the interrupts
at the supervisor.

This reworks emulation of the various "rfi" variants. I removed
some masking bits that I couldn't make sense of, the only bit that
I am aware we should mask here is POW, the CPU's MSR mask should
take care of the rest.
This also fixes some problems when running 32-bit userspace under
a 64-bit kernel.
This patch broke 32bit OpenBIOS when run under a 970 cpu. A fix was
proposed here :

This patch marks usb-bot as hot-pluggable device, makes attached
property settable and turns off auto-attach in case the device
was hotplugged.
Hot-plugging a usb-bot device with one or more scsi devices can be
done this way now:
(1) device-add usb-bot,id=foo
(2) device-add scsi-{hd,cd},bus=foo.0,lun=0
(2b) optionally add more devices (luns 0 ... 15).
(3) qom-set foo.attached = true

USB devices in attached state are visible to the guest. This patch adds
a QOM property for this. Write access is opt-in per device. Some
devices manage attached state automatically (usb-host, usb-serial,
usb-redir), so we can't enable write access universally but have to do
it on a case by case base. So far, no device opts in.

Commit 9432e53a5b added xen_sysdev as a
system device to serve as an anchor for removable virtual buses. This
introduced a build failure for non-x86 builds with CONFIG_XEN_BACKEND
set, as xen_sysdev was defined in a x86 specific file while being
consumed in an architecture independent source.
Move the xen_sysdev definition and initialization to xen_backend.c to
avoid the build failure.

In case the word size of the domU and qemu running the qdisk backend
differ BLKIF_OP_DISCARD will not work reliably, as the request
structure in the ring have different layouts for different word size.
Correct this by copying the request structure in case of different
word size element by element in the BLKIF_OP_DISCARD case, too.

Every IOMMU has some granularity which MemoryRegionIOMMUOps::translate
uses when translating, however this information is not available outside
the translate context for various checks.
This adds a get_min_page_size callback to MemoryRegionIOMMUOps and
a wrapper for it so IOMMU users (such as VFIO) can know the minimum
actual page size supported by an IOMMU.
As IOMMU MR represents a guest IOMMU, this uses TARGET_PAGE_SIZE
as fallback.
This removes vfio_container_granularity() and uses new helper in
memory_region_iommu_replay() when replaying IOMMU mappings on added
IOMMU memory region.

The 75x and 74xx processors have some thermal monitoring SPRs that
some OSes such as MacOS do use. Our current "dumb" implementation
isn't good enough and will cause some versions of MacOS to hang during
boot.
This lifts an improved emulation from MacOnLinux and adapts it to
qemu, thus fixing the problem.

Support for 0 value for memeory coherence is optional and with ppc64
we can always enable memory coherence. Linux kernel did that during
the development of 4.7 kernel. But that resulted in failure in Qemu
in H_ENTER hcall due to below check. The mentioned change was reverted
in the kernel and kernel right now enable memory coherence only if
cache inhibited is not set. Nevertheless update qemu WIMG flag check
to cover the case where we enable memory coherence along with cache
inhibited flag.
In order to handle older and newer kernel version consider both Cache
inhibitted and (cache inhibitted | memory conference) as valid values
for wimg flags.

Artyom has been working on QEMU's SPARC emulation for several years, providing
initial support for Solaris under qemu-system-sparc and more recently bugfixes
for qemu-system-sparc64 and TCG patch reviews. As work progresses on improving
emulation for sun4u machines and beyond, Artyom has agreed to take on
co-maintainership of SPARC with a focus on 64-bit architecture.
