[Qemu-devel] [PULL 01/24] test-thread-pool: be more reliable

[Paolo Bonzini]

There is a rare race between the atomic_cmpxchg and
bdrv_aio_cancel/bdrv_aio_cancel_async invocations.  Detect it, the
only sensible we can do about it is to exit long_cb immediately.

[Qemu-devel] [PULL 02/24] vl: make -accel help to list enabled accelerators only

[Paolo Bonzini]

From: Wainer dos Santos Moschetta <wainersm@redhat.com>

Currently, -accel help shows all possible accelerators regardless
if they are enabled in the binary or not. That is a different
semantic from -cpu and -machine helps, for example. So this change
makes it to list only the accelerators which support is compiled
in the binary target.

Note that it does not check if the accelerator is enabled in the
host, so the help message's header was rewritten to emphasize
that. Also qtest is not displayed given that it is used for
internal testing purpose only.

[Qemu-devel] [PULL 05/24] i386: Enable IA32_MISC_ENABLE MWAIT bit when exposing mwait/monitor

[Paolo Bonzini]

From: Wanpeng Li <wanpengli@tencent.com>

The CPUID.01H:ECX[bit 3] ought to mirror the value of the MSR
IA32_MISC_ENABLE MWAIT bit and as userspace has control of them
both, it is userspace's job to configure both bits to match on
the initial setup.

[Qemu-devel] [PULL 06/24] edu: mmio: allow 64-bit access

[Paolo Bonzini]

From: Li Qiang <liq3ea@163.com>

The edu spec says the MMIO area can be accessed by 64-bit.
However currently the 'max_access_size' is not so the MMIO
access dispatch can only access 32-bit one time. This patch fixes
this to respect the spec.

[Qemu-devel] [PULL 08/24] edu: uses uint64_t in dma operation

[Paolo Bonzini]

From: Li Qiang <liq3ea@163.com>

The dma related variable dma.dst/src/cnt is dma_addr_t, it is
uint64_t in x64 platform. Change these usage from uint32_to
uint64_t to avoid trancation in edu_dma_timer.

[Paolo Bonzini]

Allow choosing the bus that the device will be placed on, in case
the machine has more than one.  Otherwise, the bus may not match
the base address of the controller we attach it to.

[Qemu-devel] [PULL 10/24] qgraph: fix qos_node_contains with options

[Paolo Bonzini]

Currently, if qos_node_contains was passed options, it would still
create an edge without any options.  Instead, in that case
NULL acts as a terminator.

[Qemu-devel] [PULL 11/24] libqos: move common i2c code to libqos

[Paolo Bonzini]

The functions to read/write 8-bit or 16-bit registers are the same
in tmp105 and pca9552 tests, and in fact they are a special case of
"read block"/"write block" functionality; read block in turn is used
in ds1338-test.

Move everything inside libqos-test, removing the duplication.  Account
for the small differences by adding to tmp105-test.c the "read register
after writing" behavior that is specific to it.

[Qemu-devel] [PULL 12/24] libqos: fix omap-i2c receiving more than 4 bytes

[Paolo Bonzini]

If more than 4 bytes are received, the FIFO cannot host the entire
contents of the transfer and STP will be nonzero before entering
the transfer loop.  Also, CNT will contain the number of bytes
left to be transferred instead of the total number of bytes in
the transfer.

(Reverse engineered from the omap_i2c.c source code; no available
datasheet).

This will fix ds1338-test for omap-i2c.

[Qemu-devel] [PULL 13/24] pca9552-test: do not rely on state across tests

[Paolo Bonzini]

receive_autoinc is relying on the LED state that is set by
send_and_receive.  Stop doing that, because qgraph resets the
machine between tests.

[Qemu-devel] [PULL 15/24] libqos: split I2CAdapter initialization and allocation

[Paolo Bonzini]

Provide *_init functions that populate an I2CAdapter struct without
allocating one, and make the existing *_create functions wrap them.

Because in the new setup *_create might return a pointer inside the
IMXI2C or OMAPI2C struct, create companion *_free functions to go
back to the outer pointer.

All this is temporary until allocation will be handled entirely by
qgraph.

[Qemu-devel] [PULL 16/24] libqos: convert I2C to qgraph

[Paolo Bonzini]

Create an i2c-bus interface, corresponding to the I2CAdapter struct.
Wrap IMXI2C and OMAPI2C with a QOSGraphObject, and add the get_driver
function to retrieve the I2CAdapter.

The conversion is still not complete; for simplicity, i2c_recv and
i2c_send (along with their wrappers) still take an adapter/address
pair.  Fixing that would be complicated until the tests are converted
to qgraph, so it is left for after the conversion.

[Qemu-devel] [PULL 21/24] libqos: i2c: move address into QI2CDevice

[Paolo Bonzini]

This removes the hardcoded I2C address from the tests.  The address
is passed via QOSGraphEdgeOptions to i2c_device_create and stored
in the QI2CDevice.

The i2c_send and i2c_recv functions, along with their wrappers,
therefore, can be changed to take a QI2CDevice rather than an
adapter/address pair.

[Qemu-devel] [PULL 22/24] ci: store Patchew configuration in the tree

[Paolo Bonzini]

Patchew cannot yet retrieve the configuration from the QEMU Git tree, but
this is planned.  In the meanwhile, let's start storing it as YAML
so that the Patchew configuration (currently accessible only to administrators)
is public and documented.

[Qemu-devel] [PULL 24/24] q35: Revert to kernel irqchip

[Paolo Bonzini]

From: Alex Williamson <alex.williamson@redhat.com>

Commit b2fc91db8447 ("q35: set split kernel irqchip as default") changed
the default for the pc-q35-4.0 machine type to use split irqchip, which
turned out to have disasterous effects on vfio-pci INTx support.  KVM
resampling irqfds are registered for handling these interrupts, but
these are non-functional in split irqchip mode.  We can't simply test
for split irqchip in QEMU as userspace handling of this interrupt is a
significant performance regression versus KVM handling (GeForce GPUs
assigned to Windows VMs are non-functional without forcing MSI mode or
re-enabling kernel irqchip).

The resolution is to revert the change in default irqchip mode in the
pc-q35-4.1 machine and create a pc-q35-4.0.1 machine for the 4.0-stable
branch.  The qemu-q35-4.0 machine type should not be used in vfio-pci
configurations for devices requiring legacy INTx support without
explicitly modifying the VM configuration to use kernel irqchip.
