Fast mem and devices snapshots (#16)
* Run docker probe only if docker or podman are available
The docker probe uses "sudo -n" which can cause an e-mail with a security warning
each time when configure is run. Therefore run docker probe only if either docker
or podman are available.
That avoids the problematic "sudo -n" on build environments which have neither
docker nor podman installed.

* tests/avocado/machine_aspeed.py: Reduce noise on the console for SDK tests
The Aspeed SDK images are based on OpenBMC which starts a lot of
services. The output noise on the console can break from time to time
the test waiting for the logging prompt.
Change the U-Boot bootargs variable to add "quiet" to the kernel
command line and reduce the output volume. This also drops the test on
the CPU id which was nice to have but not essential.

* tests/avocado: introduce alpine virt test for CI
The boot_linux tests download and run a full cloud image boot and
start a full distro. While the ability to test the full boot chain is
worthwhile it is perhaps a little too heavy weight and causes issues
in CI. Fix this by introducing a new alpine linux ISO boot in
machine_aarch64_virt.
This boots a fully loaded -cpu max with all the bells and whistles in
31s on my machine. A full debug build takes around 180s on my machine
so we set a more generous timeout to cover that.
We don't add a test for lesser GIC versions although there is some
coverage for that already in the boot_xen.py tests. If we want to
introduce more comprehensive testing we can do it with a custom kernel
and initrd rather than a full distro boot.

* vhost: mask VIRTIO_F_RING_RESET for vhost and vhost-user devices
Commit 69e1c14aa2 ("virtio: core: vq reset feature negotation support")
enabled VIRTIO_F_RING_RESET by default for all virtio devices.
This feature is not currently emulated by QEMU, so for vhost and
vhost-user devices we need to make sure it is supported by the offloaded
device emulation (in-kernel or in another process).
To do this we need to add VIRTIO_F_RING_RESET to the features bitmap
passed to vhost_get_features(). This way it will be masked if the device
does not support it.
This issue was initially discovered with vhost-vsock and vhost-user-vsock,
and then also tested with vhost-user-rng which confirmed the same issue.
They fail when sending features through VHOST_SET_FEATURES ioctl or
VHOST_USER_SET_FEATURES message, since VIRTIO_F_RING_RESET is negotiated
by the guest (Linux >= v6.0), but not supported by the device.

* acpi: x86: move RPQx field back to _SB scope
Commit 47a373faa6b2 (acpi: pc/q35: drop ad-hoc PCI-ISA bridge AML routines and let bus ennumeration generate AML)
moved ISA bridge AML generation to respective devices and was using
aml_alias() to provide PRQx fields in _SB. scope. However, it turned
out that SeaBIOS was not able to process Alias opcode when parsing DSDT,
resulting in lack of keyboard during boot (SeaBIOS console, grub, FreeDOS).
While fix for SeaBIOS is posted
https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/RGPL7HESH5U5JRLEO6FP77CZVHZK5J65/
fixed SeaBIOS might not make into QEMU-7.2 in time.
Hence this workaround that puts PRQx back into _SB scope
and gets rid of aliases in ISA bridge description, so
DSDT will be parsable by broken SeaBIOS.
That brings back hardcoded references to ISA bridge
PCI0.S08.P40C/PCI0.SF8.PIRQ
where middle part now is auto generated based on slot it's
plugged in, but it should be fine as bridge initialization
also hardcodes PCI address of the bridge so it can't ever
move. Once QEMU tree has fixed SeaBIOS blob, we should be able
to drop this part and revert back to alias based approach

* target/arm: Don't do two-stage lookup if stage 2 is disabled
In get_phys_addr_with_struct(), we call get_phys_addr_twostage() if
the CPU supports EL2. However, we don't check here that stage 2 is
actually enabled. Instead we only check that inside
get_phys_addr_twostage() to skip stage 2 translation. This means
that even if stage 2 is disabled we still tell the stage 1 lookup to
do its page table walks via stage 2.
This works by luck for normal CPU accesses, but it breaks for debug
accesses, which are used by the disassembler and also by semihosting
file reads and writes, because the debug case takes a different code
path inside S1_ptw_translate().
This means that setups that use semihosting for file loads are broken
(a regression since 7.1, introduced in recent ptw refactoring), and
that sometimes disassembly in debug logs reports "unable to read
memory" rather than showing the guest insns.
Fix the bug by hoisting the "is stage 2 enabled?" check up to
get_phys_addr_with_struct(), so that we handle S2 disabled the same
way we do the "no EL2" case, with a simple single stage lookup.

* target/arm: Use signed quantity to represent VMSAv8-64 translation level
The LPA2 extension implements 52-bit virtual addressing for 4k and 16k
translation granules, and for the former, this means an additional level
of translation is needed. This means we start counting at -1 instead of
0 when doing a walk, and so 'level' is now a signed quantity, and should
be typed as such. So turn it from uint32_t into int32_t.
This avoids a level of -1 getting misinterpreted as being >= 3, and
terminating a page table walk prematurely with a bogus output address.

beginning of each node that we handle here.
However, if we omit the path, we should make sure to not recurse
into child nodes in between, so that it is clear to which node
each property belongs. Thus store the children and links in a
temporary list and recurse only at the end of each node, when
all properties have already been printed.

A warning, "qemu: warning: console: no gl-unblock within" followed by
guest scanout lockup can happen if dpy_gl_update is called in a row
and the second call is made before gd_draw_event scheduled by the first
call is taking place. This is because draw call returns without decrementing
gl_block ref count if the dmabuf was already submitted as shown below.
(gd_gl_area_draw/gd_egl_draw)
if (dmabuf) {
if (!dmabuf->draw_submitted) {
return;
} else {
dmabuf->draw_submitted = false;
}
}
So it should not schedule any redundant draw event in case draw_submitted is
already set in gd_egl_fluch/gd_gl_area_scanout_flush.

Currently the hcd-xhci-pci and hcd-xhci-sysbus devices, which are
mostly wrappers around the TYPE_XHCI device, which is a direct
subclass of TYPE_DEVICE. Since TYPE_DEVICE devices are not on any
qbus and do not get automatically reset, the wrapper devices both
reset the TYPE_XHCI device in their own reset functions. However,
they do this using device_legacy_reset(), which will reset the device
itself but not any bus it has.
Switch to device_cold_reset(), which avoids using a deprecated
function and also propagates reset along any child buses.

* hw/audio/intel-hda: don't reset codecs twice
Currently the intel-hda device has a reset method which manually
resets all the codecs by calling device_legacy_reset() on them. This
means they get reset twice, once because child devices on a qbus get
reset before the parent device's reset method is called, and then
again because we're manually resetting them.
Drop the manual reset call, and ensure that codecs are still reset
when the guest does a reset via ICH6_GCTL_RESET by using
device_cold_reset() (which resets all the devices on the qbus as well
as the device itself) instead of a direct call to the reset function.
This is a slight ordering change because the (only) codec reset now
happens before the controller registers etc are reset, rather than
once before and then once after, but the codec reset function
hda_audio_reset() doesn't care.
This lets us drop a use of device_legacy_reset(), which is
deprecated.

Jonathan Cameron reported this following NULL pointer dereference when a

terminated:
1. qemu_cleanup() closes all drives, setting blk->root to NULL
2. qemu_cleanup() calls user_creatable_cleanup(), which results in a RAM
block notifier callback because the memory-backend-file is destroyed.
3. blk_unregister_buf() is called by virtio-blk's BlockRamRegistrar
notifier callback and undefined behavior occurs.

* vhost: enable vrings in vhost_dev_start() for vhost-user devices
Commit 02b61f38d3 ("hw/virtio: incorporate backend features in features")
properly negotiates VHOST_USER_F_PROTOCOL_FEATURES with the vhost-user
backend, but we forgot to enable vrings as specified in
docs/interop/vhost-user.rst:
If ``VHOST_USER_F_PROTOCOL_FEATURES`` has not been negotiated, the
ring starts directly in the enabled state.
If ``VHOST_USER_F_PROTOCOL_FEATURES`` has been negotiated, the ring is
initialized in a disabled state and is enabled by
``VHOST_USER_SET_VRING_ENABLE`` with parameter 1.
Some vhost-user front-ends already did this by calling
vhost_ops.vhost_set_vring_enable() directly:
- backends/cryptodev-vhost.c
- hw/net/virtio-net.c
- hw/virtio/vhost-user-gpio.c
But most didn't do that, so we would leave the vrings disabled and some
backends would not work. We observed this issue with the rust version of
virtiofsd [1], which uses the event loop [2] provided by the
vhost-user-backend crate where requests are not processed if vring is
not enabled.
Let's fix this issue by enabling the vrings in vhost_dev_start() for
vhost-user front-ends that don't already do this directly. Same thing
also in vhost_dev_stop() where we disable vrings.

* hw/nvme: fix aio cancel in format
There are several bugs in the async cancel code for the Format command.
Firstly, cancelling a format operation neglects to set iocb->ret as well
as clearing the iocb->aiocb after cancelling the underlying aiocb which
causes the aio callback to ignore the cancellation. Trivial fix.
Secondly, and worse, because the request is queued up for posting to the
CQ in a bottom half, if the cancellation is due to the submission queue
being deleted (which calls blk_aio_cancel), the req structure is
deallocated in nvme_del_sq prior to the bottom half being schedulued.
Fix this by simply removing the bottom half, there is no reason to defer
it anyway.

The data->clientcert and data->clientkey pointers can indeed be unset

those.
While we're at it, I also noticed that the code is only freeing
some but not all of the allocated strings in this function, and
indeed, valgrind is also complaining about memory leaks here.
So let's call g_free() on all allocated strings to avoid leaking

rtl8139: honor large send MSS value
The Large-Send Task Offload Tx Descriptor (9.2.1 Transmit) has a Large-Send MSS value where the driver specifies the MSS. See the datasheet here: http://realtek.info/pdf/rtl8139cp.pdf The code ignores this value and uses a hardcoded MSS of 1500 bytes instead. When the MTU is less than 1500 bytes the hardcoded value results in IP fragmentation and poor performance. Use the Large-Send MSS value to correctly size Large-Send packets. Jason Wang <jasowang@redhat.com> noticed that the Large-Send MSS value mask was incorrect so it is adjusted to match the datasheet and Linux 8139cp driver. This issue was discussed in the past here: https://lore.kernel.org/all/20161114162505.GD26664@stefanha-x1.localdomain/ Reported-by: Russell King - ARM Linux <linux@armlinux.org.uk> Reported-by: Tobias Fiebig <tobias+git@fiebig.nl> Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1312 Acked-by: Jason Wang <jasowang@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-Id: <20221117165554.1773409-4-stefanha@redhat.com> |

rtl8139: keep Tx command mode 0 and 1 separate
There are two Tx Descriptor formats called mode 0 and mode 1. The mode is determined by the Large Send bit. CP_TX_IPCS (bit 18) is defined in mode 1 but the code checks the bit unconditionally. In mode 0 bit 18 is part of the Large Send MSS value. Explicitly check the Large Send bit to distinguish Tx command modes. This avoids bugs where modes are confused. Note that I didn't find any actual bugs aside from needlessly computing the IP checksum when the Large Send bit is enabled.

rtl8139: avoid clobbering tx descriptor bits
The device turns the Tx Descriptor into a Tx Status descriptor after fully reading the descriptor. This involves clearing Tx Own (bit 31) to indicate that the driver has ownership of the descriptor again as well as several other bits. The code keeps the first dword of the Tx Descriptor in the txdw0 local variable. txdw0 is reused to build the first word of the Tx Status descriptor. Later on the code uses txdw0 again, incorrectly assuming that it still contains the first dword of the Tx Descriptor. The tx offloading code misbehaves because it sees bogus bits in txdw0. Use a separate local variable for Tx Status and preserve Tx Descriptor in txdw0.

hw/intc: add implementation of GICD_IIDR to Arm GIC
a66a24585f (hw/intc/arm_gic: Implement read of GICC_IIDR) implemented this for the CPU interface register.

hw/intc: clean-up access to GIC multi-byte registers
gic_dist_readb was returning a word value which just happened to work as a result of the way we OR the data together. Lets fix it so only the explicit byte is returned for each part of GICD_TYPER. I've changed the return type to uint8_t although the overflow is only detected with an explicit -Wconversion.

hw/sd: Fix sun4i allwinner-sdhost for U-Boot
Trying to run U-Boot for Cubieboard (Allwinner A10) fails because it cannot access SD card. The problem is that FIFO register in current allwinner-sdhost implementation is at the address corresponding to Allwinner H3, but not A10. Linux kernel is not affected since Linux driver uses DMA access and does not use FIFO register for reading/writing. This patch adds new class parameter `is_sun4i` and based on that parameter uses register at offset 0x100 either as FIFO register (if sun4i) or as threshold register (if not sun4i; in this case register at 0x200 is FIFO register). Tested with U-Boot and Linux kernel image built for Cubieboard and OrangePi PC.

hw/intc/arm_gicv3: fix prio masking on pmr write
With commit 39f29e599355 ("hw/intc/arm_gicv3: Use correct number of
priority bits for the CPU") the number of priority bits was changed from
the maximum value 8 to typically 5. As a consequence a few of the lowest
bits in ICC_PMR_EL1 becomes RAZ/WI. However prior to this patch one of
these bits was still used since the supplied priority value is masked
before it's eventually right shifted with one bit. So the bit is not
lost as one might expect when the register is read again.
The Linux kernel depends on lowest valid bit to be reset to zero, see
commit 33625282adaa ("irqchip/gic-v3: Probe for SCR_EL3 being clear
before resetting AP0Rn") for details.
So fix this by masking the priority value after it may have been right
shifted by one bit.

hw/pci-host/pnv_phb: Avoid quitting QEMU if hotplug of pnv-phb-root-port fails
Currently QEMU terminates if you try to hotplug pnv-phb-root-port in
an environment where it is not supported, e.g. if doing this:
echo "device_add pnv-phb-root-port" | \
./qemu-system-ppc64 -monitor stdio -M powernv9
To avoid this problem, the pnv_phb_root_port_realize() function should
not use error_fatal when trying to set the properties which might not
be available.

That is reported by Alexander Bulekov. https://gitlab.com/qemu-project/qemu/-/issues/1309
Here, the queue_index is the index of the cvq, but in some cases cvq
does not have the corresponding NetClientState, so overflow appears.
I add a check here, ignore illegal queue_index and cvq queue_index.
Note the queue_index is below the VIRTIO_QUEUE_MAX but greater or equal
than cvq index could hit this. Other devices are similar.

Revert "hw/block/pflash_cfi: Error out if dev length isn't power of 2"
Commit 334c388f25 ("pflash_cfi: Error out if device length
isn't a power of two") aimed to finish the effort started by
commit 06f1521795 ("pflash: Require backend size to match device,
improve errors"), but unfortunately we are not quite there since
various machines are still ready to accept incomplete / oversized
pflash backend images, and now fail, i.e. on Debian bullseye:
$ qemu-system-x86_64 \
-drive \
if=pflash,format=raw,unit=0,readonly=on,file=/usr/share/OVMF/OVMF_CODE.fd
qemu-system-x86_64: Device size must be a power of two.
where OVMF_CODE.fd comes from the ovmf package, which doesn't
pad the firmware images to the flash size:
$ ls -lh /usr/share/OVMF/
-rw-r--r-- 1 root root 3.5M Aug 19 2021 OVMF_CODE_4M.fd
-rw-r--r-- 1 root root 1.9M Aug 19 2021 OVMF_CODE.fd
-rw-r--r-- 1 root root 128K Aug 19 2021 OVMF_VARS.fd
Since we entered the freeze period to prepare the v7.2.0 release,
the safest is to revert commit 334c388f25707a234c4a0dea05b9df08d.

hw/virtio: introduce virtio_device_should_start
The previous fix to virtio_device_started revealed a problem in its use by both the core and the device code. The core code should be able to handle the device "starting" while the VM isn't running to handle the restoration of migration state. To solve this duel use introduce a new helper for use by the vhost-user backends who all use it to feed a should_start variable. We can also pick up a change vhost_user_blk_set_status while we are at it which follows the same pattern.

vhost-user: Support vhost_dev_start
The motivation of adding vhost-user vhost_dev_start support is to improve backend configuration speed and reduce live migration VM downtime. Today VQ configuration is issued one by one. For virtio net with multi-queue support, backend needs to update RSS (Receive side scaling) on every rx queue enable. Updating RSS is time-consuming (typical time like 7ms). Implement already defined vhost status and message in the vhost specification [1]. (a) VHOST_USER_PROTOCOL_F_STATUS (b) VHOST_USER_SET_STATUS (c) VHOST_USER_GET_STATUS Send message VHOST_USER_SET_STATUS with VIRTIO_CONFIG_S_DRIVER_OK for device start and reset(0) for device stop. On reception of the DRIVER_OK message, backend can apply the needed setting only once (instead of incremental) and also utilize parallelism on enabling queues. This improves QEMU's live migration downtime with vhost user backend implementation by great margin, specially for the large number of VQs of 64 from 800 msec to 250 msec.

intel-iommu: PASID support
This patch introduce ECAP_PASID via "x-pasid-mode". Based on the existing support for scalable mode, we need to implement the following missing parts: 1) tag VTDAddressSpace with PASID and support IOMMU/DMA translation with PASID 2) tag IOTLB with PASID 3) PASID cache and its flush 4) PASID based IOTLB invalidation For simplicity PASID cache is not implemented so we can simply implement the PASID cache flush as a no and leave it to be implemented in the future. For PASID based IOTLB invalidation, since we haven't had L1 stage support, the PASID based IOTLB invalidation is not implemented yet. For PASID based device IOTLB invalidation, it requires the support for vhost so we forbid enabling device IOTLB when PASID is enabled now. Those work could be done in the future. Note that though PASID based IOMMU translation is ready but no device can issue PASID DMA right now. In this case, PCI_NO_PASID is used as PASID to identify the address without PASID. vtd_find_add_as() has been extended to provision address space with PASID which could be utilized by the future extension of PCI core to allow device model to use PASID based DMA translation. This feature would be useful for: 1) prototyping PASID support for devices like virtio 2) future vPASID work 3) future PRS and vSVA work Reviewed-by: Peter Xu <peterx@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com> Message-Id: <20221028061436.30093-5-jasowang@redhat.com> Reviewed-by: Michael S.

intel-iommu: drop VTDBus
We introduce VTDBus structure as an intermediate step for searching the address space. This works well with SID based matching/lookup. But when we want to support SID plus PASID based address space lookup, this intermediate steps turns out to be a burden. So the patch simply drops the VTDBus structure and use the PCIBus and devfn as the key for the g_hash_table(). This simplifies the codes and the future PASID extension. To prevent being slower for past vtd_find_as_from_bus_num() callers, a vtd_as cache indexed by the bus number is introduced to store the last recent search result of a vtd_as belongs to a specific bus.

vfio: move implement of vfio_get_xlat_addr() to memory.c
- Move the implement vfio_get_xlat_addr to softmmu/memory.c, and change the name to memory_get_xlat_addr(). So we can use this function on other devices, such as vDPA device. - Add a new function vfio_get_xlat_addr in vfio/common.c, and it will check whether the memory is backed by a discard manager. then device can have its own warning.

hmat acpi: Don't require initiator value in -numa
The "Memory Proximity Domain Attributes" structure of the ACPI HMAT
has a "Processor Proximity Domain Valid" flag that is currently
always set because Qemu -numa requires an initiator=X value
when hmat=on. Unsetting this flag allows to create more complex
memory topologies by having multiple best initiators for a single
memory target.
This patch allows -numa without initiator=X when hmat=on by keeping
the default value MAX_NODES in numa_state->nodes[i].initiator.
All places reading numa_state->nodes[i].initiator already check
whether it's different from MAX_NODES before using it.

hw/i386/acpi-build: Resolve north rather than south bridges
The code currently assumes Q35 iff ICH9 and i440fx iff PIIX. Now that more AML generation has been moved into the south bridges and since the machines define themselves primarily through their north bridges, let's switch to resolving the north bridges for AML generation instead. This also allows for easier experimentation with different south bridges in the "pc" machine, e.g. with PIIX4 and VT82xx.

hw/i386/pc.c: CXL Fixed Memory Window should not reserve e820 in bios
Early-boot e820 records will be inserted by the bios/efi/early boot
software and be reported to the kernel via insert_resource. Later, when
CXL drivers iterate through the regions again, they will insert another
resource and make the RESERVED memory area a child.
This RESERVED memory area causes the memory region to become unusable,
and as a result attempting to create memory regions with
`cxl create-region ...`
Will fail due to the RESERVED area intersecting with the CXL window.
During boot the following traceback is observed:
0xffffffff81101650 in insert_resource_expand_to_fit ()
0xffffffff83d964c5 in e820__reserve_resources_late ()
0xffffffff83e03210 in pcibios_resource_survey ()
0xffffffff83e04f4a in pcibios_init ()
Which produces a call to reserve the CFMWS area:
(gdb) p *new
$54 = {start = 0x290000000, end = 0x2cfffffff, name = "Reserved",
flags = 0x200, desc = 0x7, parent = 0x0, sibling = 0x0,
child = 0x0}
Later the Kernel parses ACPI tables and reserves the exact same area as
the CXL Fixed Memory Window:
0xffffffff811016a4 in insert_resource_conflict ()
insert_resource ()
0xffffffff81a81389 in cxl_parse_cfmws ()
0xffffffff818c4a81 in call_handler ()
acpi_parse_entries_array ()
(gdb) p/x *new
$59 = {start = 0x290000000, end = 0x2cfffffff, name = "CXL Window 0",
flags = 0x200, desc = 0x0, parent = 0x0, sibling = 0x0,
child = 0x0}
This produces the following output in /proc/iomem:
590000000-68fffffff : CXL Window 0
590000000-68fffffff : Reserved
This reserved area causes `get_free_mem_region()` to fail due to a check
against `__region_intersects()`. Due to this reserved area, the
intersect check will only ever return REGION_INTERSECTS, which causes
`cxl create-region` to always fail.

msix: Assert that specified vector is in range
There were several different ways to deal with the situation where the vector specified for a msix function is out of bound: - early return a function and keep progresssing - propagate the error to the caller - mark msix unusable - assert it is in bound - just ignore An out-of-bound vector should not be specified if the device implementation is correct so let msix functions always assert that the specified vector is in range. An exceptional case is virtio-pci, which allows the guest to configure vectors. For virtio-pci, it is more appropriate to introduce its own checks because it is sometimes too late to check the vector range in msix functions.

acpi: pc/35: sanitize _GPE declaration order
Move _GPE block declaration before it gets referenced by other hotplug handlers. While at it move PCI hotplug (_E01) handler after PCI tree description to avoid forward reference to to not yet declared methods/devices. PS: Forward 'usage' usualy is fine as long as it's hidden within method, however 'iasl' may print warnings. So be nice to iasl/guest OS and do things in proper order. PS2: Also follow up patches will move some of hotplug code from PCI tree to _E01 and that also requires PCI Device nodes build first, before Scope can reuse that from global context.

acpi: pc/q35: drop ad-hoc PCI-ISA bridge AML routines and let bus ennumeration generate AML
PCI-ISA bridges that are built in PIIX/Q35 are building its own AML using AcpiDevAmlIf interface. Now build_append_pci_bus_devices() gained AcpiDevAmlIf interface support to get AML of devices atached to PCI slots. So drop ad-hoc build_q35_isa_bridge()/build_piix4_isa_bridge() and let PCI bus enumeration to include PCI-ISA bridge AML when it's enumerated by build_append_pci_bus_devices(). AML change is mostly contextual, which moves whole ISA hierarchy directly under PCI host bridge instead of it being described as separate \SB.PCI0.ISA block. Note: If bus/slot that hosts ISA bridge has BSEL set, it will gain new ASUN and _DMS entries (i.e. acpi-index support, but it should not cause any functional change and that is fine from PCI Firmware spec point of view), potentially it's possible to suppress that by adding a flag to PCIDevice but I don't see a reason to do that yet, I'd rather treat bridge just as any other PCI device if it's possible.
