Nicholas Piggin ccc5a4c5e1 spapr: Add SPAPR_CAP_AIL_MODE_3 for AIL mode 3 support for H_SET_MODE hcall
The behaviour of the Address Translation Mode on Interrupt resource is
not consistently supported by all CPU versions or all KVM versions: KVM
HV does not support mode 2, and does not support mode 3 on POWER7 or
early POWER9 processesors. KVM PR only supports mode 0. TCG supports all
modes (0, 2, 3) on CPUs with support for the corresonding LPCR[AIL] mode.
This leads to inconsistencies in guest behaviour and could cause problems
migrating guests.

This was not noticable for Linux guests for a long time because the
kernel only uses modes 0 and 3, and it used to consider AIL-3 to be
advisory in that it would always keep the AIL-0 vectors around, so it
did not matter whether or not interrupts were delivered according to
the AIL mode. Recent Linux guests depend on AIL mode 3 working as
specified in order to support the SCV facility interrupt. If AIL-3 can
not be provided, then H_SET_MODE must return an error to Linux so it can
disable the SCV facility (failure to do so can lead to userspace being
able to crash the guest kernel).

Add the ail-mode-3 capability to specify that AIL-3 is supported. AIL-0
is implied as the baseline, and AIL-2 is no longer supported by spapr.
AIL-2 is not known to be used by any software, but support in TCG could
be restored with an ail-mode-2 capability quite easily if a regression
is reported.

Modify the H_SET_MODE Address Translation Mode on Interrupt resource
handler to check capabilities and correctly return error if not
supported.

KVM has a cap to advertise support for AIL-3.

Emanuele Giuseppe Esposito aef04fc790 thread-pool: avoid passing the pool parameter every time
thread_pool_submit_aio() is always called on a pool taken from
qemu_get_current_aio_context(), and that is the only intended
use: each pool runs only in the same thread that is submitting
work to it, it can't run anywhere else.

Therefore simplify the thread_pool_submit* API and remove the
ThreadPool function parameter.

BALATON Zoltan fb27a3e9e7 hw/ppc/pegasos2: Fix PCI interrupt routing
According to the PegasosII schematics the PCI interrupt lines are
connected to both the gpp pins of the Mv64361 north bridge and the
PINT pins of the VT8231 south bridge so guests can get interrupts from
either of these. So far we only had the MV64361 connections which
worked for on board devices but for additional PCI devices (such as
network or sound card added with -device) guest OSes expect interrupt
from the ISA IRQ 9 where the firmware routes these PCI interrupts in
VT8231 ISA bridge. After the previous patches we can now model this
and also remove the board specific connection from mv64361. Also
configure routing of these lines when using Virtual Open Firmware to
match board firmware for guests that expect this.

This fixes PCI interrupts on pegasos2 under Linux, MorphOS and AmigaOS.

Frederic Barrat ddf0676f1a pnv_phb4_pec: Simplify/align code to parent user-created PHBs
When instantiating a user-created PHB on P9/P10, we don't really have
a reason any more to go through an indirection in pnv_chip_add_phb()
in pnv.c, we can go straight to the right function in
pnv_phb4_pec.c. That way, default PHBs and user-created PHBs are all
handled in the same file.  This patch also renames pnv_phb4_get_pec()
to pnv_pec_add_phb() to better reflect that it "hooks" a PHB to a PEC.

For P8, the PHBs are parented to the chip directly, so it makes sense
to keep calling pnv_chip_add_phb() in pnv.c, to also be consistent
with where default PHBs are handled. The only change here is that,
since that function is now only used for P8, we can refine the return
type.

So overall, the PnvPHB front-end now has a pnv_phb_user_get_parent()
function which handles the parenting of the user-created PHBs by
calling the right function in the right file based on the processor
version. It's also easily extensible if we ever need to support a
different parent object.

Frederic Barrat fa9dc22aec pnv_phb4_pec: Move pnv_phb4_get_pec() to rightful file
The function pnv_phb4_get_pec() exposes some internals of the PEC and
PHB logic, yet it was in the higher level hw/ppc/pnv.c file for
historical reasons: P8 implements the PHBs from pnv.c directly, but on
P9/P10, it's done through the CEC model, which has its own file. So
move pnv_phb4_get_pec() to hw/pci-host/pnv_phb4_pec.c, where it fits
naturally.

While at it, replace the PnvPHB4 parameter by the PnvPHB front-end,
since it has all the information needed and simplify it a bit.

No functional changes.

Markus Armbruster 2c6fe2e214 include/hw/ppc: Split pnv_chip.h off pnv.h
PnvChipClass, PnvChip, Pnv8Chip, Pnv9Chip, and Pnv10Chip are defined
in pnv.h.  Many users of the header don't actually need them.  One
instance is this inclusion loop: hw/ppc/pnv_homer.h includes
hw/ppc/pnv.h for typedef PnvChip, and vice versa for struct PnvHomer.

Similar structs live in their own headers: PnvHomerClass and PnvHomer
in pnv_homer.h, PnvLpcClass and PnvLpcController in pci_lpc.h,
PnvPsiClass, PnvPsi, Pnv8Psi, Pnv9Psi, Pnv10Psi in pnv_psi.h, ...

Move PnvChipClass, PnvChip, Pnv8Chip, Pnv9Chip, and Pnv10Chip to new
pnv_chip.h, and adjust include directives.  This breaks the inclusion
loop mentioned above.

Philippe Mathieu-Daudé 883f2c591f bulk: Rename TARGET_FMT_plx -> HWADDR_FMT_plx
The 'hwaddr' type is defined in "exec/hwaddr.h" as:

    hwaddr is the type of a physical address
   (its size can be different from 'target_ulong').

All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx:

 $ fgrep define include/exec/hwaddr.h
 #define HWADDR_H
 #define HWADDR_BITS 64
 #define HWADDR_MAX UINT64_MAX
 #define TARGET_FMT_plx "%016" PRIx64
         ^^^^^^
 #define HWADDR_PRId PRId64
 #define HWADDR_PRIi PRIi64
 #define HWADDR_PRIo PRIo64
 #define HWADDR_PRIu PRIu64
 #define HWADDR_PRIx PRIx64
 #define HWADDR_PRIX PRIX64

Since hwaddr's size can be *different* from target_ulong, it is
very confusing to read one of its format using the 'TARGET_FMT_'
prefix, normally used for the target_long / target_ulong types:

$ fgrep TARGET_FMT_ include/exec/cpu-defs.h
 #define TARGET_FMT_lx "%08x"
 #define TARGET_FMT_ld "%d"
 #define TARGET_FMT_lu "%u"
 #define TARGET_FMT_lx "%016" PRIx64
 #define TARGET_FMT_ld "%" PRId64
 #define TARGET_FMT_lu "%" PRIu64

Apparently this format was missed during commit a8170e5e97
("Rename target_phys_addr_t to hwaddr"), so complete it by
doing a bulk-rename with:

 $ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx)

Markus Armbruster edf5ca5dbe include/hw/pci: Split pci_device.h off pci.h
PCIDeviceClass and PCIDevice are defined in pci.h.  Many users of the
header don't actually need them.  Similar structs live in their own

pci_bridge.h, PCIHostBridgeClass and PCIHostState in pci_host.h,
PCIExpressHost in pcie_host.h, and PCIERootPortClass, PCIEPort, and
PCIESlot in pcie_port.h.

Move PCIDeviceClass and PCIDeviceClass to new pci_device.h, along with
the code that needs them.  Adjust include directives.

This also enables the next commit.

Currently objects including "hw/ppc/spapr.h" are forced to be
target specific due to the inclusion of "vof.h" in "spapr.h".

"spapr.h" only uses a Vof pointer, so doesn't require the structure
declaration. The only place where Vof structure is accessed is in
spapr.c, so include "vof.h" there, and forward declare the structure
in "spapr.h".

Markus Armbruster 047f2ca1ce qapi qdev qom: Elide redundant has_FOO in generated C
The has_FOO for pointer-valued FOO are redundant, except for arrays.
They are also a nuisance to work with.  Recent commit "qapi: Start to
elide redundant has_FOO in generated C" provided the means to elide
them step by step.  This is the step for qapi/qdev.json and
qapi/qom.json.

Said commit explains the transformation in more detail.  The invariant
violations mentioned there do not occur here.

Markus Armbruster 66997c42e0 cleanup: Tweak and re-run return_directly.cocci
Tweak the semantic patch to drop redundant parenthesis around the
return expression.

Coccinelle drops a comment in hw/rdma/vmw/pvrdma_cmd.c; restored
manually.

Coccinelle messes up vmdk_co_create(), not sure why.  Change dropped,
will be done manually in the next commit.

Line breaks in target/avr/cpu.h and hw/rdma/vmw/pvrdma_cmd.c tidied up
manually.

Whitespace in tools/virtiofsd/fuse_lowlevel.c tidied up manually.

checkpatch.pl complains "return of an errno should typically be -ve"
two times for hw/9pfs/9p-synth.c.  Preexisting, the patch merely makes
it visible to checkpatch.pl.

Bernhard Beschow 9eb6abbf6a hw/isa/vt82c686: Instantiate IDE function in host device
The IDE function is closely tied to the ISA function (e.g. the IDE
interrupt routing happens there), so it makes sense that the IDE
function is instantiated within the south bridge itself.

Stefan Hajnoczi 179938097d ppc patch queue for 2022-10-29:
This queue has the second part of the ppc4xx_sdram cleanups, doorbell
 instructions for POWER8,  new pflash handling for the e500 machine and a
 Radix MMU regression fix.
 
 It also has a lot of performance optimizations in the PowerPC emulation
 done by the researchers of the Eldorado institute. Between using gvec
 for VMX/VSX instructions, a full rework of the interrupt model and PMU
 optimizations, they managed to drastically speed up the emulation of
 powernv8/9/10 machines.  Here's an example with avocado tests:

Bernhard Beschow 63e4bf8e84 hw/ppc/e500: Implement pflash handling
Allows e500 boards to have their root file system reside on flash using
only builtin devices located in the eLBC memory region.

Note that the flash memory area is only created when a -pflash argument is
given, and that the size is determined by the given file. The idea is to
put users into control.

Daniel Henrique Barboza d890f2fa9f hw/ppc: set machine->fdt in spapr machine
The pSeries machine never bothered with the common machine->fdt
attribute. We do all the FDT related work using spapr->fdt_blob.

We're going to introduce a QMP/HMP command to dump the FDT, which will
rely on setting machine->fdt properly to work across all machine
archs/types.

Let's set machine->fdt in two places where we manipulate the FDT:
spapr_machine_reset() and CAS. There are other places where the FDT is
manipulated in the pSeries machines, most notably the hotplug/unplug
path. For now we'll acknowledge that we won't have the most accurate
representation of the FDT, depending on the current machine state, when
using this QMP/HMP fdt command. Making the internal FDT representation
always match the actual FDT representation that the guest is using is a
problem for another day.

spapr->fdt_blob is left untouched for now. To replace it with
machine->fdt, since we're migrating spapr->fdt_blob, we would need to
migrate machine->fdt as well. This is something that we would like to to
do keep our code simpler but it's also a work we'll leave for later.
