Here are the corrections needed for the queue ring buffer size
calculation for the following cases:
- Remove the KIQ VM flush ring usage.
- Add the invalidate TLBs packet for gfx10 and gfx11 queue.
- There's no VM flush and PFP sync, so remove the gfx9 real
ring and compute ring buffer usage.

Do VRAM accounting when doing migrations to vram to make sure
there is enough available VRAM and migrating to VRAM doesn't evict
other possible non-unified memory BOs. If migrating to VRAM fails,
driver can fall back to using system memory seamlessly.

During mode-2 reset, pci config space registers are affected at device
side. However, certain platforms have switches which assign virtual BAR
addresses and returns the same even after device is reset. This
affects pci_restore_state() as it doesn't issue another config write, if
the value read is same as the saved value.
Add a workaround to write saved config space values from driver side.
Presently, these switches are in platforms with SMU v13.0.6 SOCs, hence
restrict the workaround only to those.

Make SVM BOs more likely to get evicted than other BOs. These BOs
opportunistically use available VRAM, but can fall back relatively
seamlessly to system memory. It also avoids SVM migrations evicting
other, more important BOs as they will evict other SVM allocations
first.

IIO: 1st set of new device support, features and cleanup for 6.10
The Analog Device team (Paul Cercueil and Nuno Sa) have been working on
improving high speed device handling. They have had some support in their
own tree for many years, so it is great to see them bring it to upstream.
Some of that is seen here, with the first output device using the
IIO dmaengine infrastructure and a new DAC backend FPGA IP driver.
This makes use of a new set of interfaces to allow backend and
front end driver communication in a fashion that in theory at least
allows for a single driver for a given ADC / DAC independent of
the IP to which is being used to deal with the data bus and DMA aspects
of working with these devices. It is early days for this new
generic way of handling split devices, but as it's kernel internals only
we can merrily change anything about it as a wider diversity of devices
show up and we get a better feel for what works.
Alongside the usual set of new drivers and features we have
the automatic cleanup of fwnode_handle_put() which didn't quite make
it in last cycle. The equivalent DT version was merged by Rob Herring
via the DT binding tree and one patch using that in IIO can also be
found in this pull request. Rob has been making extensive use of that
infrastructure in the DT core which is good to see and provides more
evidence this basic approach is useful.
In some cases, the IIO driver was converted over from DT only to
using the generic firmware description handling of property.h
including using the new macros. The general preference for IIO
is to use this more generic handling where possible - a bunch of other
drivers have been converted this cycle as well.
New device support
==================
adi,ad7173
- New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8,
AD7176-2 and AD7177-2 ADCs.
- Follow up fix for an accidental use of logic not instead of bitwise.
adi,ad7944
- New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs.
- Later patch added use of new spi_optimize_message() to reduce overheads
of setting up a reused message.
- Additional changes later in series reduced code duplication.
adi,ad9739a RF DAC
- New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface.
adi,axi-dac
- Support for this FPGA IP used to send data to high performance DACs over
an interface such as JESD204B/C or parallel interfaces. Used in
conjunction with a DAC driver. The initial user is the ad9739a.
The dmaengine-buffer needed various changes to make it bidirectional.
avago,apds9306
- New driver for this ambient light sensor.
- Fix much later in this pull for an off by 1 error.
New device IDs
==============
For these at most an ID and a instance of chip specific data was needed.
Always nice to see manufacturers sticking to an existing software interface
for new parts.
allwinner,sun20i
- Add support for h616.
invensense,mpu6050
- Add support for ICM42688
maxim,max30102
- Add compatible for MAX30101
ti,dac5571
- Add compatible for DAC081C081
General
=======
fwnode_handle
- Support for cleanup.h based __free(fwnode_handle)
- Loop macro using this for looping over child nodes without needing to
call fwnode_handle_put() in ever early exit from the loop.
- Used in:
* adi,ad3552r
* adi,ad4130
* adi,ad5770r
* adi,ad74413r
* adi,ad7173
* adi,adfm2000
* linear,ltc2688
* linear,ltc2983
* maxim,max11410
* microchip,pac1934
* qcom,spmi-adc
* renesas,rz2gl
* st,ab8500
* st,stm32 (Fix for failure to set return value precedes this patch,
providing an example of why enabling direct returns makes bugs
less likely)
- Conversions to fwnode also using the cleanup logic
* adi,ad7124
* adi,ad7292
* freescale,fsl-imx25-gcq
- Other conversions to fwnode where the new cleanup handling isn't useful
* adi,ad7192
* avia,hx711
* freescale,mma8452
* nxp,fxls8962af
* st,spear
* ti,twl4030
Features
========
adi,adxl345
- Support SPI_3WIRE mode.
adi,ad9944
- Support 3-wire mode, note this isn't normal 3-wire SPI (unlike the
adxl345 change above), but rather a wiring scheme where the SPI
chip select is used to trigger conversions rather than using a
separate pin.
- Add some device specific documentation, mostly around the various wiring
schemes.
invensense,mpu6050
- Add Wake on Motion support as an IIO event and as a wake-up source.
linear,ltc2983
- Add vdd-supply.
ti,hdc3020
- Add power management using trigger on demand mode and adding suspend and
resume handling.
- Use reset GPIO if available.
Cleanup and fixes
================
iio core
- Use the various autocleanup and lock guards from cleanup.h to simplify
the IIO core.
- Don't set the pointer used for iio_priv() if it is zero sized as that
points beyond the end of the allocation. No driver actually uses it
in that case but good to clean this up.
various drivers
- Drop unnecessary casts of other pointer types to void *
docs
- Add missing ABI entry for in_temp_input.
adi,adx345
- General cleanup prior to adding spi-3wire mode.
adi,axi-adc
- Be more flexible and allow minor version changes as these are expected
to be backwards compatible.
avago,apds9300/9600
- Merge near identical bindings. The drivers are quite different, but
the bindings can be shared. The apds9306 binding introduced in this
series uses this shared binding doc as well.
- Add missing vdd-supply
- Update binding to use IRQ_TYPE_LEVEL_LOW instead of 8.
bosch,bmp280
- Organize headers
freescale,fxl-imx25-gcq
- Use devm_ for remaining probe() time setup allowing dropping
of specific error handling and remove() functions.
infineon,dps310
- Fix handling of negative temperatures
- Bring style of other similar calls inline with the form needed
for temperatures
- Ensure error handling of regmap calls is consistent within the driver.
- Simplify scale reading logic.
invensense,mpu6050
- Flip logic in binding to exclude devices without i2c-gate instead
of opting in. The list is expected to be much shorter as all recent
devices support this feature.
honeywell,hsc030pa
- Use spi_read() instead of opening coding.
renesas,rcar
- Use device_for_each_child_of_node_scoped() to remove need to manually
release. Left over from series the rest of which went in during 6.9.
st,ab8500
- Fix naming of function parameters in kernel-doc

On multiport supported controllers, each port has its own DP/DM and
SuperSpeed (if super speed capable) interrupts. As per the bindings,
their interrupt names differ from single-port ones by having a "_x"

names whether the controller is a multiport controller or not.

The logic for requesting interrupts is duplicated for each interrupt. In
the upcoming patches that introduces support for multiport, it would be
better to clean up the duplication before reading mulitport related
interrupts.
Refactor interrupt setup call by adding a new helper function for
requesting the wakeup interrupts. To simplify implementation, make
the display name same as the interrupt name expected in Device tree.

Currently the DWC3 driver supports only single port controller
which requires at least one HS PHY and at most one SS PHY.
But the DWC3 USB controller can be connected to multiple ports and
each port can have their own PHYs. Each port of the multiport
controller can either be HS+SS capable or HS only capable
Proper quantification of them is required to modify GUSB2PHYCFG
and GUSB3PIPECTL registers appropriately.
DWC3 multiport controllers are capable to service at most 15 High Speed
PHYs and 4 Supser Speed PHYs. Add support for detecting, obtaining and
configuring PHYs supported by a multiport controller.

Testing with KASAN and syzkaller revealed a bug in port.c:disable_store():
usb_hub_to_struct_hub() can return NULL if the hub that the port belongs to
is concurrently removed, but the function does not check for this
possibility before dereferencing the returned value.
It turns out that the first dereference is unnecessary, since hub->intfdev
is the parent of the port device, so it can be changed easily. Adding a
check for hub == NULL prevents further problems.
The same bug exists in the disable_show() routine, and it can be fixed the
same way.

GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY should be cleared
during initialization. Suspend during initialization can result in
undefined behavior due to clock synchronization failure, which often
seen as core soft reset timeout.
The programming guide recommended these bits to be cleared during
initialization for DWC_usb3.0 version 1.94 and above (along with
DWC_usb31 and DWC_usb32). The current check in the driver does not
account if it's set by default setting from coreConsultant.
This is especially the case for DRD when switching mode to ensure the
phy clocks are available to change mode. Depending on the
platforms/design, some may be affected more than others. This is noted
in the DWC_usb3x programming guide under the above registers.
Let's just disable them during driver load and mode switching. Restore
them when the controller initialization completes.
Note that some platforms workaround this issue by disabling phy suspend
through "snps,dis_u3_susphy_quirk" and "snps,dis_u2_susphy_quirk" when
they should not need to.

This commit fixes uvc gadget support on 32-bit platforms.
Commit 0df28607c5cb ("usb: gadget: uvc: Generalise helper functions for
reuse") introduced a helper function __uvcg_iter_item_entries() to aid
with parsing lists of items on configfs attributes stores. This function
is a generalization of another very similar function, which used a
stack-allocated temporary buffer of fixed size for each item in the list
and used the sizeof() operator to check for potential buffer overruns.
The new function was changed to allocate the now variably sized temp
buffer on heap, but wasn't properly updated to also check for max buffer
size using the computed size instead of sizeof() operator.
As a result, the maximum item size was 7 (plus null terminator) on
64-bit platforms, and 3 on 32-bit ones. While 7 is accidentally just
barely enough, 3 is definitely too small for some of UVC configfs
attributes. For example, dwFrameInteval, specified in 100ns units,
usually has 6-digit item values, e.g. 166666 for 60fps.

The OS descriptors logic had the high/low byte of w_value inverted, causing
the extended properties to not be accessible for interface != 0.
>From the Microsoft documentation:

OS_Desc_CompatID.doc (w_index = 0x4):
- wValue:
High Byte = InterfaceNumber. InterfaceNumber is set to the number of the
interface or function that is associated with the descriptor, typically
0x00. Because a device can have only one extended compat ID descriptor,
it should ignore InterfaceNumber, regardless of the value, and simply
return the descriptor.
Low Byte = 0. PageNumber is used to retrieve descriptors that are larger
than 64 KB. The header section is 16 bytes, so PageNumber is set to 0 for
this request.
We currently do not support >64KB compat ID descriptors, so verify that the
low byte is 0.

- wValue:
High byte = InterfaceNumber. The high byte of wValue is set to the number

Low byte = PageNumber. The low byte of wValue is used to retrieve

FFS based applications can utilize the aio_cancel() callback to dequeue
pending USB requests submitted to the UDC. There is a scenario where the
FFS application issues an AIO cancel call, while the UDC is handling a
soft disconnect. For a DWC3 based implementation, the callstack looks
like the following:
DWC3 Gadget FFS Application
dwc3_gadget_soft_disconnect() ...
--> dwc3_stop_active_transfers()
--> dwc3_gadget_giveback(-ESHUTDOWN)
--> ffs_epfile_async_io_complete() ffs_aio_cancel()
--> usb_ep_free_request() --> usb_ep_dequeue()
There is currently no locking implemented between the AIO completion
handler and AIO cancel, so the issue occurs if the completion routine is
running in parallel to an AIO cancel call coming from the FFS application.
As the completion call frees the USB request (io_data->req) the FFS
application is also referencing it for the usb_ep_dequeue() call. This can
lead to accessing a stale/hanging pointer.
commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently")
relocated the usb_ep_free_request() into ffs_epfile_async_io_complete().
However, in order to properly implement locking to mitigate this issue, the
spinlock can't be added to ffs_epfile_async_io_complete(), as
usb_ep_dequeue() (if successfully dequeuing a USB request) will call the
function driver's completion handler in the same context. Hence, leading
into a deadlock.
Fix this issue by moving the usb_ep_free_request() back to
ffs_user_copy_worker(), and ensuring that it explicitly sets io_data->req
to NULL after freeing it within the ffs->eps_lock. This resolves the race
condition above, as the ffs_aio_cancel() routine will not continue
attempting to dequeue a request that has already been freed, or the
ffs_user_copy_work() not freeing the USB request until the AIO cancel is
done referencing it.
This fix depends on
commit b566d38857fc ("usb: gadget: f_fs: use io_data->status
consistently")
Fixes: 2e4c7553cd6f ("usb: gadget: f_fs: add aio support")

In V3D, the conclusion of a job is indicated by a IRQ. When a job
finishes, then we update the local and the global GPU stats of that
queue. But, while the GPU stats are being updated, a user might be
reading the stats from sysfs or fdinfo.
For example, on `gpu_stats_show()`, we could think about a scenario where
`v3d->queue[queue].start_ns != 0`, then an interrupt happens, we update
the value of `v3d->queue[queue].start_ns` to 0, we come back to
`gpu_stats_show()` to calculate `active_runtime` and now,
`active_runtime = timestamp`.
In this simple example, the user would see a spike in the queue usage,
that didn't match reality.
In order to address this issue properly, use a seqcount to protect read
and write sections of the code.

Currently, we manually perform all operations to update the GPU stats
variables. Apart from the code repetition, this is very prone to errors,
as we can see on commit 35f4f8c9fc97 ("drm/v3d: Don't increment
`enabled_ns` twice").
Therefore, create two functions to manage updating all GPU stats
variables. Now, the jobs only need to call for `v3d_job_update_stats()`
when the job is done and `v3d_job_start_stats()` when starting the job.

We enumerate devices by attempting config reads to the Vendor ID of each
possible device. On conventional PCI, if no device responds, the read
terminates with a Master Abort (PCI r3.0, sec 6.1). On PCIe, the config
read is terminated as an Unsupported Request (PCIe r6.0, sec 2.3.2,
7.5.1.3.7). In either case, if the read addressed a device below a bridge,
it is logged by setting "Received Master Abort" in the bridge Secondary
Status register.
Clear any errors logged in the Secondary Status register after enumeration.
