Yicong Yang 97f4effeb6 hw/acpi/aml-build: Only generate cluster node in PPTT when specified
Currently we'll always generate a cluster node no matter user has
specified '-smp clusters=X' or not. Cluster is an optional level
and will participant the building of Linux scheduling domains and
only appears on a few platforms. It's unncessary to always build
it when it cannot reflect the real topology on platforms having no
cluster implementation and to avoid affecting the linux scheduling
domains in the VM. So only generate the cluster topology in ACPI
PPTT when the user has specified it explicitly in -smp.

Tested qemu-system-aarch64 with `-smp 8` and linux 6.1-rc1, without
this patch:
estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_*
ff	# cluster_cpus
0-7	# cluster_cpus_list
56	# cluster_id

with this patch:
estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_*
ff	# cluster_cpus
0-7	# cluster_cpus_list
36	# cluster_id, with no cluster node kernel will make it to
	  physical package id

Longpeng c672f348cb vdpa-dev: get iova range explicitly
In commit a585fad26b ("vdpa: request iova_range only once") we remove
GET_IOVA_RANGE form vhost_vdpa_init, the generic vdpa device will start
without iova_range populated, so the device won't work. Let's call
GET_IOVA_RANGE ioctl explicitly.

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
headers: PCIBusClass and PCIBus in pci_bus.h, PCIBridge in
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.

Hyman Huang(黄勇) c9bdc449f9 vhost-user: Fix the virtio features negotiation flaw
This patch aims to fix unexpected negotiation features for
vhost-user netdev interface.

When openvswitch reconnect Qemu after an unexpected disconnection
and Qemu therefore start the vhost_dev, acked_features field in
vhost_dev is initialized with value fetched from acked_features
field in NetVhostUserState, which should be up-to-date at that
moment but Qemu could not make it actually during the time window
of virtio features negotiation.

So we save the acked_features right after being configured by
guest virtio driver so it can be used to restore acked_features
field in vhost_dev correctly.

Bin Meng 5decd2c521 hw/intc: sifive_plic: Change "priority-base" to start from interrupt source 0
At present the SiFive PLIC model "priority-base" expects interrupt
priority register base starting from source 1 instead source 0,
that's why on most platforms "priority-base" is set to 0x04 except
'opentitan' machine. 'opentitan' should have set "priority-base"
to 0x04 too.

Note the irq number calculation in sifive_plic_{read,write} is
correct as the codes make up for the irq number by adding 1.

Let's simply update "priority-base" to start from interrupt source
0 and add a comment to make it crystal clear.

changed the value of VIRT_IRQCHIP_NUM_SOURCES from 127 to 53, which

While we are here, we also fix the comments of platform bus irq range

Conor Dooley 592f0a9429 hw/{misc, riscv}: pfsoc: add system controller as unimplemented
The system controller on PolarFire SoC is access via a mailbox. The
control registers for this mailbox lie in the "IOSCB" region & the
interrupt is cleared via write to the "SYSREG" region. It also has a
QSPI controller, usually connected to a flash chip, that is used for
storing FPGA bitstreams and used for In-Application Programming (IAP).

Linux has an implementation of the system controller, through which the
hwrng is accessed, leading to load/store access faults.

Add the QSPI as unimplemented and a very basic (effectively
unimplemented) version of the system controller's mailbox. Rather than
purely marking the regions as unimplemented, service the mailbox
requests by reporting failures and raising the interrupt so a guest can
better handle the lack of support.

Crypto Processor and does not show up on the MSS memory map either.

FIC 0, 1 & 3 do show up in the MSS memory map and neither FICs 0 or 1
are represented in QEMU, leading to load access violations while booting
Linux for Icicle if PCIe is enabled as the root port is connected via
either FIC 0 or 1.

Conor Dooley 13cd1d6eaf hw/misc: pfsoc: add fabric clocks to ioscb
On PolarFire SoC, some peripherals (eg the PCI root port) are clocked by
"Clock Conditioning Circuitry" in the FPGA. The specific clock depends
on the FPGA bitstream & can be locked to one particular {D,P}LL - in the
Icicle Kit Reference Design v2022.09 or later this is/will be the case.

Linux v6.1+ will have a driver for this peripheral and devicetrees that
previously relied on "fixed-frequency" clock nodes have been switched
over to clock-controller nodes. The IOSCB region is represented in QEMU,
but the specific region of it that the CCCs occupy has not so v6.1-rcN
kernels fail to boot in QEMU.

Add the regions as unimplemented so that the status-quo in terms of boot
is maintained.

Richard Henderson 39004a71d8 tcg: Reorg function calls
Pre-compute the function call layout for each helper at startup.
Drop TCG_CALL_DUMMY_ARG, as we no longer need to leave gaps
in the op->args[] array.  This allows several places to stop
checking for NULL TCGTemp, to which TCG_CALL_DUMMY_ARG mapped.

For tcg_gen_callN, loop over the arguments once.  Allocate the TCGOp
for the call early but delay emitting it, collecting arguments first.
This allows the argument processing loop to emit code for extensions
and have them sequenced before the call.

For tcg_reg_alloc_call, loop over the arguments in reverse order,
which allows stack slots to be filled first naturally.

Philippe Mathieu-Daudé 46d80a56a1 hw/ppc/spapr: Reduce "vof.h" inclusion
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".

Philippe Mathieu-Daudé c0a55a0c9d hw/sd/sdhci: Support big endian SD host controller interfaces
Some SDHCI IP can be synthetized in various endianness:
https://github.com/u-boot/u-boot/blob/v2021.04/doc/README.fsl-esdhc

 - CONFIG_SYS_FSL_ESDHC_BE

   ESDHC IP is in big-endian mode. Accessing ESDHC registers can be
   determined by ESDHC IP's endian mode or processor's endian mode.

Our current implementation is little-endian. In order to support
big endianness:

- Rename current MemoryRegionOps as sdhci_mmio_le_ops ('le')
- Add an 'endianness' property to SDHCIState (default little endian)
- Set the 'io_ops' field in realize() after checking the property
- Add the sdhci_mmio_be_ops (big-endian) MemoryRegionOps.

Code has not been used practically since its inception (2004)

or maybe even earlier, but it was consuming contributors time
as QEMU was being rewritten.
Drop it for now. Whomever would like to actually
use the thing, can make sure it actually works/reintroduce
it back when there is a user.

PS:
I've stumbled upon this when replacing PCIDeviceClass::is_bridge
field with QOM cast to PCI_BRIDGE type. Unused DEC 21154
was the only one trying to use the field with plain PCIDevice.
It's not worth keeping the field around for the sake of the code
that was commented out 'forever'.

Begin weaning user-only away from PageDesc.

Since, for user-only, all TB (and page) manipulation is done with
a single mutex, and there is no virtual/physical discontinuity to
split a TB across discontinuous pages, place all of the TBs into
a single IntervalTree. This makes it trivial to find all of the
TBs intersecting a range.

Retain the existing PageDesc + linked list implementation for
system mode.  Move the portion of the implementation that overlaps
the new user-only code behind the common ifdef.

Peter Maydell f4c636b0c2 pci: Convert child classes of TYPE_PCIE_ROOT_PORT to 3-phase reset
Convert the TYPE_CXL_ROOT_PORT and TYPE_PNV_PHB_ROOT_PORT classes to
3-phase reset, so they don't need to use the deprecated
device_class_set_parent_reset() function any more.

We have to do both in the same commit, because they keep the
parent_reset field in their common parent class's class struct.

Note that pnv_phb_root_port_class_init() was pointlessly setting
dc->reset twice, once by calling device_class_set_parent_reset()
and once directly.

Convert the child classes TYPE_PS2_KBD_DEVICE and
TYPE_PS2_MOUSE_DEVICE to the 3-phase reset system.  This allows us to
stop using the old device_class_set_parent_reset() function.

We don't need to register an 'exit' phase function for the
subclasses, because they have no work to do in that phase.  Passing
NULL to resettable_class_set_parent_phases() will result in the
parent class method being called for that phase, so we don't need to
register a function purely to chain to the parent 'exit' phase
function.

Thomas Huth 3d81e8cf0c hw/misc: Move some arm-related files from specific_ss into softmmu_ss
The header target/arm/kvm-consts.h checks CONFIG_KVM which is marked as
poisoned in common code, so the files that include this header have to
be added to specific_ss and recompiled for each, qemu-system-arm and
qemu-system-aarch64. However, since the kvm headers are only optionally
used in kvm-constants.h for some sanity checks, we can additionally
check the NEED_CPU_H macro first to avoid the poisoned CONFIG_KVM macro,
so kvm-constants.h can also be used from "common" files (without the
sanity checks - which should be OK since they are still done from other
target-specific files instead). This way, and by adjusting some other
include statements in the related files here and there, we can move some
files from specific_ss into softmmu_ss, so that they only need to be
compiled once during the build process.

Kevin Wolf 1b3ff9feb9 block: GRAPH_RDLOCK for functions only called by co_wrappers
The generated coroutine wrappers already take care to take the lock in
the non-coroutine path, and assume that the lock is already taken in the
coroutine path.

The only thing we need to do for the wrapped function is adding the
GRAPH_RDLOCK annotation. Doing so also allows us to mark the
corresponding callbacks in BlockDriver as GRAPH_RDLOCK_PTR.

Emanuele Giuseppe Esposito 90830f5950 block: use co_wrapper_mixed_bdrv_rdlock in functions taking the rdlock
Take the rdlock already, before we add the assertions.

All these functions either read the graph recursively, or call
BlockDriver callbacks that will eventually need to be protected by the
graph rdlock.

Do it now to all functions together, because many of these recursively
call each other.

For example, bdrv_co_truncate calls BlockDriver->bdrv_co_truncate, and
some driver callbacks implement their own .bdrv_co_truncate by calling
bdrv_flush inside. So if bdrv_flush asserts but bdrv_truncate does not
take the rdlock yet, the assertion will always fail.

Emanuele Giuseppe Esposito e6d3f7a602 block-coroutine-wrapper.py: introduce annotations that take the graph rdlock
Add co_wrapper_bdrv_rdlock and co_wrapper_mixed_bdrv_rdlock option to
the block-coroutine-wrapper.py script.

This "_bdrv_rdlock" option takes and releases the graph rdlock when a
coroutine function is created.

This means that when used together with "_mixed", the function marked
with co_wrapper_mixed_bdrv_rdlock will support both coroutine and
non-coroutine case, and in the latter case it will create a coroutine
that takes and releases the rdlock. When called from a coroutine, the
caller must already hold the graph lock.

Example:
void co_wrapper_mixed_bdrv_rdlock bdrv_f1();

Becomes

static void bdrv_co_enter_f1()
{
    bdrv_graph_co_rdlock();
    bdrv_co_function();
    bdrv_graph_co_rdunlock();
}

void bdrv_f1()
{
    if (qemu_in_coroutine) {
        assume_graph_lock();
        bdrv_co_function();
    } else {
        qemu_co_enter(bdrv_co_enter_f1);
        ...
    }
}

When used alone, the function will not work in coroutine context, and
when called in non-coroutine context it will create a new coroutine that
takes care of taking and releasing the rdlock automatically.

Example:
void co_wrapper_bdrv_rdlock bdrv_f1();

Becomes

static void bdrv_co_enter_f1()
{
    bdrv_graph_co_rdlock();
    bdrv_co_function();
    bdrv_graph_co_rdunlock();
}

void bdrv_f1()
{
    assert(!qemu_in_coroutine());
    qemu_co_enter(bdrv_co_enter_f1);
    ...
}

About their usage:
- co_wrapper does not take the rdlock, so it can be used also outside
  the block layer.
- co_wrapper_mixed will be used by many blk_* functions, since the
  coroutine function needs to call blk_wait_while_drained() and
  the rdlock *must* be taken afterwards, otherwise it's a deadlock.
  In the future this annotation will go away, and blk_* will use
  co_wrapper directly.
- co_wrapper_bdrv_rdlock will be used by BlockDriver callbacks, ideally
  by all of them in the future.
- co_wrapper_mixed_bdrv_rdlock will be used by the remaining functions
  that are still called by coroutine and non-coroutine context. In the
  future this annotation will go away, as we will split such mixed
  functions.
