Randy Dunlap 26bea42771 Documentation: ioctl: add entry for nsfs.h
All userspace ioctls major/magic number should be documented in
Documentation/userspace-api/ioctl/ioctl-number.rst, so add
the entry for <linux/nsfs.h>.

Linus Torvalds e229b429bb Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for
 5.12-rc1.  Over time it seems like this tree is collecting more and more
 tiny driver subsystems in one place, making it easier for those
 maintainers, which is why this is getting larger.
 
 Included in here are:
 	- coresight driver updates
 	- habannalabs driver updates
 	- virtual acrn driver addition (proper acks from the x86
 	  maintainers)
 	- broadcom misc driver addition
 	- speakup driver updates
 	- soundwire driver updates
 	- fpga driver updates
 	- amba driver updates
 	- mei driver updates
 	- vfio driver updates
 	- greybus driver updates
 	- nvmeem driver updates
 	- phy driver updates
 	- mhi driver updates
 	- interconnect driver udpates
 	- fsl-mc bus driver updates
 	- random driver fix
 	- some small misc driver updates (rtsx, pvpanic, etc.)
 
 All of these have been in linux-next for a while, with the only reported
 issue being a merge conflict in include/linux/mod_devicetable.h that you
 will hit in your tree due to the dfl_device_id addition from the fpga
 subsystem in here.  The resolution should be simple.

Linus Torvalds 825d150875 cxl for 5.12
Introduce an initial driver for CXL 2.0 Type-3 Memory Devices. CXL is
 Compute Express Link which released the 2.0 specification in November.
 The Linux relevant changes in CXL 2.0 are support for an OS to
 dynamically assign address space to memory devices, support for
 switches, persistent memory, and hotplug. A Type-3 Memory Device is a
 PCI enumerated device presenting the CXL Memory Device Class Code and
 implementing the CXL.mem protocol. CXL.mem allows device to advertise
 CPU and I/O coherent memory to the system, i.e. typical "System RAM" and
 "Persistent Memory" in Linux /proc/iomem terms.
 
 In addition to the CXL.mem fast path there is an administrative command
 hardware mailbox interface for maintenance and provisioning. It is this
 command interface that is the focus of the initial driver. With this
 driver a CXL device that is mapped by the BIOS can be administered by
 Linux. Linux support for CXL PMEM and dynamic CXL address space
 management are to be implemented post v5.12.

This series consists of the usual driver updates (ufs, ibmvfc,

 is bound to cause conflicts with a trivial change somewhere).  The

Ben Widawsky 583fa5e71c cxl/mem: Add basic IOCTL interface
Add a straightforward IOCTL that provides a mechanism for userspace to
query the supported memory device commands. CXL commands as they appear
to userspace are described as part of the UAPI kerneldoc. The command
list returned via this IOCTL will contain the full set of commands that
the driver supports, however, some of those commands may not be
available for use by userspace.

Memory device commands first appear in the CXL 2.0 specification. They
are submitted through a mailbox mechanism specified in the CXL 2.0
specification.

The send command allows userspace to issue mailbox commands directly to
the hardware. The list of available commands to send are the output of
the query command. The driver verifies basic properties of the command
and possibly inspect the input (or output) payload to determine whether
or not the command is allowed (or might taint the kernel).

Shuo Liu 9c5137aedd virt: acrn: Introduce VM management interfaces
The VM management interfaces expose several VM operations to ACRN
userspace via ioctls. For example, creating VM, starting VM, destroying
VM and so on.

The ACRN Hypervisor needs to exchange data with the ACRN userspace
during the VM operations. HSM provides VM operation ioctls to the ACRN
userspace and communicates with the ACRN Hypervisor for VM operations
via hypercalls.

HSM maintains a list of User VM. Each User VM will be bound to an
existing file descriptor of /dev/acrn_hsm. The User VM will be
destroyed when the file descriptor is closed.

Ioana Ciornei 2cf1e703f0 bus: fsl-mc: add fsl-mc userspace support
Adding userspace support for the MC (Management Complex) means exporting
an ioctl capable device file representing the root resource container.

This new functionality in the fsl-mc bus driver intends to provide
userspace applications an interface to interact with the MC firmware.

Commands that are composed in userspace are sent to the MC firmware
through the FSL_MC_SEND_MC_COMMAND ioctl.  By default the implicit MC
I/O portal is used for this operation, but if the implicit one is busy,
a dynamic portal is allocated and then freed upon execution.

The command received through the ioctl interface is checked against a
known whitelist of accepted MC commands. Commands that attempt a change
in hardware configuration will need CAP_NET_ADMIN, while commands used
in debugging do not need it.

The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter which
was manufactured by the now-defunct ICP Vortex company, later acquired by
Adaptec and superseded by the aacraid series of controllers.  The driver
itself would require a major overhaul before any modifications can be
attempted, but seeing that it's unlikely to have any users left it should
rather be removed completely.

Mark Pearson 8e0cbf3563 Documentation: Add documentation for new platform_profile sysfs attribute
On modern systems the platform performance, temperature, fan and other
hardware related characteristics are often dynamically configurable. The
profile is often automatically adjusted to the load by some
automatic-mechanism (which may very well live outside the kernel).

These auto platform-adjustment mechanisms often can be configured with
one of several 'platform-profiles', with either a bias towards low-power
consumption or towards performance (and higher power consumption and
thermals).

Introduce a new platform_profile sysfs API which offers a generic API for
selecting the performance-profile of these automatic-mechanisms.

that uses 4 bytes per pixel) and formats with 8 bits per pixel (stored
in 3 or 4 bytes). For the latter category, the names use a components
order convention that is the opposite of the first category, and the
opposite of DRM pixel formats. This has led to lots of confusion in the
past, and would really benefit from being explained more precisely. Do
so, which also prepares for the addition of additional RGB pixels
formats.

Mauro Carvalho Chehab 38d8dfe0a9 media: pixfmt-meta-rkisp1.rst: fix two build warnings
With Sphinx 2.x: those two warnings are produced:

/devel/v4l/docs/sphinx2/Documentation/output/videodev2.h.rst:6: WARNING: undefined label: v4l2-meta-fmt-rk-isp1-params (if the link has no caption the label must precede a section header)

The reason is that there's no blank line between the two
identifiers.

Hans Verkuil 3abfc314c5 media: vicodec: add V4L2_ prefix before FWHT_VERSION and FWHT_FL_*
The FWHT stateless 'uAPI' was staging and marked explicitly in the
V4L2 specification that it will change and is unstable.
Note that these control IDs were never exported as a public API,
they were only defined at the driver's code.

While not too late, let's rename them is preparation for promoting
the stateless FWHT codec API as a public API.
