ppc patch queue 2019-06-12
Next pull request against qemu-4.1. The big thing here is adding
support for hot plug of P2P bridges, and PCI devices under P2P bridges
on the "pseries" machine (which doesn't use SHPC). Other than that
there's just a handful of fixes and small enhancements.

Commit 58ea30f5145 "Clean up header guards that don't match their file
name" messed up contrib/elf2dmp/qemu_elf.h and
tests/migration/migration-test.h.
It missed target/cris/opcode-cris.h and
tests/uefi-test-tools/UefiTestToolsPkg/Include/Guid/BiosTablesTest.h
due to the scripts/clean-header-guards.pl bug fixed in the previous
commit.
Commit a8b991b52dc "Clean up ill-advised or unusual header guards"
missed include/hw/xen/io/ring.h for the same reason.
Commit 3979fca4b69 "disas: Rename include/disas/bfd.h back to

This is the common header guard idiom:
/*
* File comment
*/
#ifndef GUARD_SYMBOL_H
#define GUARD_SYMBOL_H
... actual contents ...
#endif
A few of our headers have some #include before the guard.
target/tilegx/spr_def_64.h has #ifndef __DOXYGEN__ outside the guard.
A few more have the #define elsewhere.
Change them to match the common idiom. For spr_def_64.h, that means
dropping #ifndef __DOXYGEN__. While there, rename guard symbols to
make scripts/clean-header-guards.pl happy.

The pseries machine type already allows PCI hotplug and unplug via the
PAPR mechanism, but only on the root bus of each PHB. This patch extends
this to allow PCI to PCI bridges to be hotplugged, and devices to be
hotplugged or unplugged under P2P bridges.
For now we disallow hot unplugging P2P bridges. I tried doing that, but
haven't managed to get it working, I think due to some guest side problems
that need further investigation.
To do this we dynamically construct DRCs when bridges are hot (or cold)
added, which can in turn be used to hotplug devices under the bridge.

A P2P bridge will attempt to handle the hotplug with SHPC, which doesn't
work in the PAPR environment. Instead we want to direct all PCI hotplug
actions to the PAPR specific host bridge which will use the PAPR hotplug
mechanism.

DRC ids are more or less arbitrary, as long as they're consistent. For
PCI, we notionally build them from the phb's index along with PCI bus
number, slot and function number.
Using bus number is broken, however, because it can change if the guest
re-enumerates the PCI topology for whatever reason (e.g. due to hotplug
of a bridge, which we don't support yet but want to).
Fortunately, there's an alternative. Bridges are required to have a unique
non-zero "chassis number" that we can use instead. Adjust the code to
use that instead.
This looks like it would introduce a guest visible breaking change, but
in fact it does not because we don't yet ever use non-zero bus numbers.
Both chassis and bus number are always 0 for the root bus, so there's no
change for the existing cases.

spapr_pci.c currently has several confusingly similarly named functions for
various conversions between representations of DRCs. Make things clearer
by renaming things in a more consistent XXX_from_YYY() manner and remove
some called-only-once variants in favour of open coding.
While we're at it, move this code together in the file to avoid some extra
forward references, and split out construction and removal of DRCs for the
host bridge into helper functions.

Device nodes for PCI bridges (both host and P2P) describe both the bridge
device itself and the bus hanging off it, handling of this is a bit of a
mess.
spapr_dt_pci_device() has a few things it only adds for non-bridges, but
always adds #address-cells and #size-cells which should only appear for
bridges. But the walking down the subordinate PCI bus is done in one of
its callers spapr_populate_pci_devices_dt(). The PHB dt creation in
spapr_populate_pci_dt() open codes some similar logic to the bridge case.
This patch consolidates things in a bunch of ways:
* Bus specific dt info is now created in spapr_dt_pci_bus() used for both
P2P bridges and the host bridge. This includes walking subordinate
devices
* spapr_dt_pci_device() now calls spapr_dt_pci_bus() when called on a
P2P bridge
* We do detection of bridges with the is_bridge field of the device class,
rather than checking PCI config space directly, for consistency with
qemu's core PCI code.
* Several things are renamed for brevity and clarity

spapr_create_pci_child_dt() is a trivial wrapper around
spapr_populate_pci_child_dt(), but is the latter's only caller. So fold
them together into spapr_dt_pci_device(), which closer matches our modern
naming convention.
While there, make a number of cleanups to the function itself. This is
mostly using more temporary locals to avoid awkwardly long lines, and in
some cases avoiding double reads of PCI config space variables.

spapr_populate_pci_child_dt() adds a 'name' property to the device tree
node for PCI devices. This is never necessary for a flattened device tree,
it is implicit in the name added when the node is constructed. In fact
anything we do add to a 'name' property will be overwritten with something
derived from the structural name in the guest firmware (but in fact it is
exactly the same bytes).
So, remove that. In addition, pci_get_node_name() is very simple, so fold
it into its (also simple) sole caller spapr_create_pci_child_dt().
While we're there rename pci_find_device_name() to the shorter and more
accurate dt_name_from_class().

Every PHB must have a unique index. This is checked at realize but when
a duplicate index is detected, an error message mentioning BUIDs is
printed. This doesn't help much, especially since BUID is an internal
concept that is no longer exposed to the user.
Fix the message to mention the index property instead of BUID. As a bonus
print a list of indexes already in use.

Other accelerators have their own headers: sysemu/hax.h, sysemu/hvf.h,
sysemu/kvm.h, sysemu/whpx.h. Only tcg_enabled() & friends sit in
qemu-common.h. This necessitates inclusion of qemu-common.h into
headers, which is against the rules spelled out in qemu-common.h's
file comment.
Move tcg_enabled() & friends into their own header sysemu/tcg.h, and
adjust #include directives.

i386 (32 bit) emulation uses EFER in wrmsr and in MMU fault
processing.
But it does not included in VMState, because "efer" field is disabled with
This patch adds a section for 32-bit targets which saves EFER when
it's value is non-zero.

Add a "unavailable-features" QOM property to X86CPU objects that
have the same semantics of "unavailable-features" on
query-cpu-definitions. The new property has the same goal of
"filtered-features", but is generic enough to let any kind of CPU
feature to be listed there without relying on low level details
like CPUID leaves or MSR numbers.

Extract feature name listing code from
x86_cpu_class_check_missing_features(). It will be reused to
return information about CPU filtered features at runtime.

There was nothing armv7 specific about the bic+cmp sequence, however
looking at the set of guests more closely shows that the 8-bit immediate
operand for the bic can only be satisfied with one guest in tree:
baseline m-profile -- 10-bit pages with aligned 4-byte memory ops.
Therefore it does not seem useful to keep this path.

This changes the code generation for the tlb from e.g.
ldr ip, [r6, #-0x10]
ldr r2, [r6, #-0xc]
and ip, ip, r4, lsr #8
ldrd r0, r1, [r2, ip]!
ldr r2, [r2, #0x18]
to
ldrd r0, r1, [r6, #-0x10]
and r0, r0, r4, lsr #8
ldrd r2, r3, [r1, r0]!
ldr r1, [r1, #0x18]
for armv7 hosts. Rearranging the register allocation in
order to avoid overlap between the two ldrd pairs causes
the patch to be larger than it ordinarily would be.

This macro is now always empty, so remove it. This leaves the
entire contents of CPUArchState under the control of the guest

We have for some time had code within the tcg backends to
handle large positive offsets from env. This move makes
sure that need not happen. Indeed, we are able to assert
at build time that simple offsets suffice for all hosts.

Amusingly, we had already ignored the comment to keep this value
at the end of CPUState. This restores the minimum negative offset
from TCG_AREG0 for code generation.
For the couple of uses within qom/cpu.c, without NEED_CPU_H, add
a pointer from the CPUState object to the IcountDecr object within
CPUNegativeOffsetState.

Cleanup in the boilerplate that each target must define.
Replace xtensa_env_get_cpu with env_archcpu. The combination
CPU(xtensa_env_get_cpu) should have used ENV_GET_CPU to begin;
use env_cpu now.
Move cpu_get_tb_cpu_state below the include of "exec/cpu-all.h"
so that the definition of env_cpu is available.
