Move the write to DISP_GAMMA_CFG to enable the Gamma LUT to after
programming the actual table to avoid potential visual glitches during
table modification.
Note:
GAMMA should get enabled in between vblanks, but this requires many
efforts in order to make this happen, as that requires migrating all
of the writes to make use of CMDQ instead of cpu writes and that's
not trivial. For this reason, this patch only moves the LUT enable.
The CMDQ rework will come at a later time.

The commit referenced in the Fixes tag had a couple problems (as
pointed out by Dan):
- qmp_put was never called, resulting in refcnt leaks
- failling to acquire the QMP mailbox on A7xx would not undo the probe
function properly
- the qmp_put call present in the code was unreachable

If the drm/msm init code gets an error during output modeset
initialisation, the kernel will report an error regarding DRM memory
manager not being clean during shutdown. This is because
msm_dsi_modeset_init() allocates a piece of GEM memory for the TX
buffer, but destruction of the buffer happens only at
msm_dsi_host_destroy(), which is called during DSI driver's remove()
time, much later than the DRM MM shutdown.
To solve this issue, move the TX buffer destruction to dsi_unbind(), so
that the buffer is destructed at the correct time. Note, we also have to
store a reference to the address space, because priv->kms->aspace is
cleared before components are unbound.

TEST_LENGTH passing ".size = sizeof(struct _struct) - 1" expects -EINVAL
from "if (ucmd.user_size < op->min_size)" check in iommufd_fops_ioctl().
This has been working when min_size is exactly the size of the structure.
However, if the size of the structure becomes larger than min_size, i.e.
the passing size above is larger than min_size, that min_size sanity no
longer works.
Since the first test in TEST_LENGTH() was to test that min_size sanity
routine, rework it to support a min_size calculation, rather than using
the full size of the structure.

In an MST topology the DSC capabilities are specific to each connector,
retrieved either from the sink if it decompresses the stream, or from a
branch device between the source and the sink in case this branch device
does the decompression. Accordingly each connector needs to cache its
own DSC DPCD and FEC capabilities, along with the AUX device through
which the decompression can be enabled. This patch prepares for that by
storing the capabilities and the DSC AUX device in the connector, for
now these just matching the version stored in intel_dp. The follow-up
patches will convert all users to look up these in the connector instead
of intel_dp, after which the intel_dp copies are removed.

The SM7125 platform is introduced, with support for Xiaomi Redmi Note 9
Pro. Support for Fairphone 5, on QCM6490, and BQ Aquaris M5, on MSM8939,
are introduced.
With the various QMP PHY bindings having been refactored, SC7180,
SC7280, SDM845, SM8150, and SM8250 are transitioned to the new USB/DP
combo PHY binding. IPQ6018, IPQ8074 MSM8998, SC7280, SC8180X, SDM845,
SM8150, SM8250, and SM8450 are transitioned to the new PCIe PHY binding,
and SC8180X is transitioned to the new UFS phy binding.
The UFS power supply situation is clarified, and a range of boards
across MSM8996, MSM8998, SM4250, SM6115, SM6125, SM8350, SM8450, and
SM8550 receives corrections for this.
On IPQ5018 watchdog support is introduced, and the SCM driver has SDI
(debug image) enabled - so that it can be disabled. On IPQ5332 USB is
enabled. The hwspinlock identifier is corrected across IPQ5332, IPQ6018,
IPQ8074 and IPQ9574.
The reserved-memory ranges for the remoteprocs on MSM8916 boards are
refactored, to reduce the amount of duplicated boilerplate definitions.
A number of nodes are transitioned to be disabled by default, to
facilitate new boards.
Samsung Galaxy Tab A 8.0 and Samsung Galaxy Tab A 9.7 gains display
support, and the latter capacitive keys. Samsung Galaxy J5 gains
accelerometer support. The Dragonboard 410c gains missing ADC7533
regulator definition, and an overlay forcing the board to operate in
host mode, for automation purposes.
On MSM8976, the outgoing IPC bits for modem and wcss are corrected, and
reserved-memory regions are updated.
Incorrect reserved-memory regions are also corrected for MSM8992 and
MSM8994 devices.
The QRB2210 RB1 board gets debug UART moved per hardware update.
regulator voltage ranges are corrected, remoteprocs are enabled, USB
SuperSpeed PHY is enabled, and GPIO LEDs are introduced for Bluetooth,
WiFi and a user LED.
Interrupts are described for the SGMII PHYs on SA8775P Ride platform,
and the inline crypto engine is introduced for UFS.
On SC7180 the audio DSP remoteproc is introduced. Additional SKUs of the
Lazor boards are added.The RT5682 audio codec part is reorganized to be
easier to maintain. On Trogdor devices, the touchscreen and display
panels are linked to improve the power cycling behavior across the two.
On SC7280 the cpuidle states are rewritten to support OS-initiated PCSI
mode. LMH interrupts are added, to receive feedback when throttling
occurs. The embedded usb debugger (EUD) description and the dummy
usb-c-connector node is removed, as this is not correctly described. The
USB3 pipe clock input of the global clock controller is properly
described.
Modem remoteproc is introduced on SDM630, and the SDM670 PDC mapping is
corrected.
On the SDM845 MTP PCIe support is introduced. The volumn down and reset
buttons are defined. Remoteproc firmware names and the WiFI
configuration is corrected.
On Sony Xperia XZ2, XZ2 Compact, and XZ3 GPIO lines names are provided
for TLMM and PMICs. The camera regulators are also added.
Display hardware blocks are added to SM6125, and enabled on Sony Xperia
10 II.
The ref clock is wired up to PCIe PHY on SM8150.
On SM8250/QRB5165, and the RB5 board, the DisplayPort controller and the
TCPM is introduced, with all the plumbing to get USB role and
orientation switching, as well as DisplayPort altmode to work.
Interconnects and power-domains are also described for the QUPs on this
platform.
Previously ignored PMICs are described for the SM8350 Hardware
Development Kit (HDK), and PMR735a regulators are introduced. The
pinctrl state for uart18 is corrected.
On SM8450 HDK audio routes are corrected, to enable the analog
microphones on the board. The addition of the PRNG is reverted, in favor
of an upcoming additon of a true RNG.
Constants are replaced with QCOM_SCM_VMID_* defines on a variety of
boards.
The SM8550 QRD board gets Bluetooth support, and the camera clock
controller is described.
Additionally, a number of fixes are introduced in a variety of platforms

Qualcomm ARM64 DeviceTree updates for v6.7
The SM7125 platform is introduced, with support for Xiaomi Redmi Note 9
Pro. Support for Fairphone 5, on QCM6490, and BQ Aquaris M5, on MSM8939,
are introduced.
With the various QMP PHY bindings having been refactored, SC7180,
SC7280, SDM845, SM8150, and SM8250 are transitioned to the new USB/DP
combo PHY binding. IPQ6018, IPQ8074 MSM8998, SC7280, SC8180X, SDM845,
SM8150, SM8250, and SM8450 are transitioned to the new PCIe PHY binding,
and SC8180X is transitioned to the new UFS phy binding.
The UFS power supply situation is clarified, and a range of boards
across MSM8996, MSM8998, SM4250, SM6115, SM6125, SM8350, SM8450, and
SM8550 receives corrections for this.
On IPQ5018 watchdog support is introduced, and the SCM driver has SDI
(debug image) enabled - so that it can be disabled. On IPQ5332 USB is
enabled. The hwspinlock identifier is corrected across IPQ5332, IPQ6018,
IPQ8074 and IPQ9574.
The reserved-memory ranges for the remoteprocs on MSM8916 boards are
refactored, to reduce the amount of duplicated boilerplate definitions.
A number of nodes are transitioned to be disabled by default, to
facilitate new boards.
Samsung Galaxy Tab A 8.0 and Samsung Galaxy Tab A 9.7 gains display
support, and the latter capacitive keys. Samsung Galaxy J5 gains
accelerometer support. The Dragonboard 410c gains missing ADC7533
regulator definition, and an overlay forcing the board to operate in
host mode, for automation purposes.
On MSM8976, the outgoing IPC bits for modem and wcss are corrected, and
reserved-memory regions are updated.
Incorrect reserved-memory regions are also corrected for MSM8992 and
MSM8994 devices.
The QRB2210 RB1 board gets debug UART moved per hardware update.
regulator voltage ranges are corrected, remoteprocs are enabled, USB
SuperSpeed PHY is enabled, and GPIO LEDs are introduced for Bluetooth,
WiFi and a user LED.
Interrupts are described for the SGMII PHYs on SA8775P Ride platform,
and the inline crypto engine is introduced for UFS.
On SC7180 the audio DSP remoteproc is introduced. Additional SKUs of the
Lazor boards are added.The RT5682 audio codec part is reorganized to be
easier to maintain. On Trogdor devices, the touchscreen and display
panels are linked to improve the power cycling behavior across the two.
On SC7280 the cpuidle states are rewritten to support OS-initiated PCSI
mode. LMH interrupts are added, to receive feedback when throttling
occurs. The embedded usb debugger (EUD) description and the dummy
usb-c-connector node is removed, as this is not correctly described. The
USB3 pipe clock input of the global clock controller is properly
described.
Modem remoteproc is introduced on SDM630, and the SDM670 PDC mapping is
corrected.
On the SDM845 MTP PCIe support is introduced. The volumn down and reset
buttons are defined. Remoteproc firmware names and the WiFI
configuration is corrected.
On Sony Xperia XZ2, XZ2 Compact, and XZ3 GPIO lines names are provided
for TLMM and PMICs. The camera regulators are also added.
Display hardware blocks are added to SM6125, and enabled on Sony Xperia
10 II.
The ref clock is wired up to PCIe PHY on SM8150.
On SM8250/QRB5165, and the RB5 board, the DisplayPort controller and the
TCPM is introduced, with all the plumbing to get USB role and
orientation switching, as well as DisplayPort altmode to work.
Interconnects and power-domains are also described for the QUPs on this
platform.
Previously ignored PMICs are described for the SM8350 Hardware
Development Kit (HDK), and PMR735a regulators are introduced. The
pinctrl state for uart18 is corrected.
On SM8450 HDK audio routes are corrected, to enable the analog
microphones on the board. The addition of the PRNG is reverted, in favor
of an upcoming additon of a true RNG.
Constants are replaced with QCOM_SCM_VMID_* defines on a variety of
boards.
The SM8550 QRD board gets Bluetooth support, and the camera clock
controller is described.
Additionally, a number of fixes are introduced in a variety of platforms
and boards, to align with Devicetree bindings.

Linux enables MSI-X before disabling INTx, but keeps MSI-X masked until
the table is filled. Then it disables INTx just before clearing MASKALL
bit. Currently this approach is rejected by xen-pciback.
According to the PCIe spec, device cannot use INTx when MSI/MSI-X is
enabled (in other words: enabling MSI/MSI-X implicitly disables INTx).
Change the logic to consider INTx disabled if MSI/MSI-X is enabled. This
applies to three places:
- checking currently enabled interrupts type,
- transition to MSI/MSI-X - where INTx would be implicitly disabled,
- clearing INTx disable bit - which can be allowed even if MSI/MSI-X is
enabled, as device should consider INTx disabled anyway in that case

Virtio guests send VIRTIO_MMIO_QUEUE_NOTIFY notification when they need
to notify the backend of an update to the status of the virtqueue. The
backend or another entity, polls the MMIO address for updates to know
when the notification is sent.
It works well if the backend does this polling by itself. But as we move
towards generic backend implementations, we end up implementing this in
a separate user-space program.
Generally, the Virtio backends are implemented to work with the Eventfd
based mechanism. In order to make such backends work with Xen, another
software layer needs to do the polling and send an event via eventfd to
the backend once the notification from guest is received. This results
in an extra context switch.
This is not a new problem in Linux though. It is present with other
hypervisors like KVM, etc. as well. The generic solution implemented in
the kernel for them is to provide an IOCTL call to pass the address to
poll and eventfd, which lets the kernel take care of polling and raise
an event on the eventfd, instead of handling this in user space (which
involves an extra context switch).
This patch adds similar support for xen.
Inspired by existing implementations for KVM, etc..
This also copies ioreq.h header file (only struct ioreq and related
macros) from Xen's source tree (Top commit 5d84f07fe6bf ("xen/pci: drop
remaining uses of bool_t")).

Currently the handling of events is supported either in the kernel or
userspace, but not both.
In order to support fast delivery of interrupts from the guest to the
backend, we need to handle the Queue notify part of Virtio protocol in
kernel and the rest in userspace.
Update the interrupt handler registration flag to IRQF_SHARED for event
channels, which would allow multiple entities to bind their interrupt
handler for the same event channel port.
Also increment the reference count of irq_info when multiple entities
try to bind event channel to irqchip, so the unbinding happens only
after all the users are gone.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.
This code was found with the help of Coccinelle, and audited and
fixed manually.

There are no longer any users of cpus_have_const_cap(), and therefore it
can be removed.
Remove cpus_have_const_cap(). At the same time, remove
__cpus_have_const_cap(), as this is a trivial wrapper of
alternative_has_cap_unlikely(), which can be used directly instead.
The comment for __system_matches_cap() is updated to no longer refer to
cpus_have_const_cap(). As we have a number of ways to check the cpucaps,
the specific suggestions are removed.
