4cd67adc44 This tag contains habanalabs driver changes for v5.15:
- Add a new uAPI (under the cs ioctl) to enable to user to reserve
   signals and signal them from within its workloads, while the driver
   performs the waiting. This allows finer granularity of pipelining
   between the different engines and resource utilization.
 
 - Add a new uAPI (under the wait_for_cs ioctl) to allow waiting
   on multiple command submissions (workloads) at the same time. This
   is an optimization for the user process so it won't need to call
   multiple times to the wait_for_cs ioctl.
 
 - Add new feature of "state dump", which can be triggered through new
   debugfs node. This is a similar concept to the kernel panic dump.
   This new mechanism retrieves information from the device in case
   one of the workloads that was sent by the user got stuck. This is
   very helpful for debugging the hang.
 
 - Add a new debugfs node to perform lookup of user pointers that are
   mapped to habana device's pmmu.
 
 - Fix to the tracking of user process when running inside a container.
 
 - Allow user to map more than 4GB of memory to the device MMU in single
   IOCTL call.
 
 - Minimize number of register reads done in GAUDI during user operation.
 
 - Allow user to retrieve the device's server type that the device is
   connected to.
 
 - Several fixes to the code of waiting on interrupts on behalf of the
   user.
 
 - Fixes and improvements to the hint mechanism in our VA allocation.
 
 - Update the firmware header files to the latest version while
   maintaining backward compatibility with older firmware versions.
 
 - Multiple fixes to various bugs.

89b213657c habanalabs: add userptr_lookup node in debugfs
It is useful to have the ability to see which user address was pinned
to which physical address during the initial mapping. We already have
all that info stored, but no means to search this data (which may be
quite large).

ba1dc7f273 Char / Misc driver changes for 5.15-rc1
Here is the big set of char/misc driver changes for 5.15-rc1.
 
 Lots of different driver subsystems are being updated in here, notably:
 	- mhi subsystem update
 	- fpga subsystem update
 	- coresight/hwtracing subsystem update
 	- interconnect subsystem update
 	- nvmem subsystem update
 	- parport drivers update
 	- phy subsystem update
 	- soundwire subsystem update
 and there are some other char/misc drivers being updated as well:
 	- binder driver additions
 	- new misc drivers
 	- lkdtm driver updates
 	- mei driver updates
 	- sram driver updates
 	- other minor driver updates.
 
 Note, there are no habanna labs driver updates in this pull request,
 that will probably come later before -rc1 is out in a different request.
 
 All of these have been in linux-next for a while with no reported
 problems.

Pull irq updates from Thomas Gleixner:
 "Updates to the interrupt core and driver subsystems:

  Core changes:

   - The usual set of small fixes and improvements all over the place,
     but nothing stands out

  MSI changes:

   - Further consolidation of the PCI/MSI interrupt chip code

   - Make MSI sysfs code independent of PCI/MSI and expose the MSI
     interrupts of platform devices in the same way as PCI exposes them.

  Driver changes:

   - Support for ARM GICv3 EPPI partitions

   - Treewide conversion to generic_handle_domain_irq() for all chained
     interrupt controllers

   - Conversion to bitmap_zalloc() throughout the irq chip drivers

   - The usual set of small fixes and improvements"

938b793fde habanalabs: expose state dump
To improve the user's ability to debug the case where a workload that
is part of executing training/inference of a topology is getting stuck,
we need to add a 'core dump' each time a CS times-out. The 'core dump'
shall contain all relevant Sync Manager information and corresponding
fence values.

The most recent dumps shall be accessible via debugfs, under
'state_dump' node. Reading from the node will provide the oldest dump
available. Writing an integer value X will discard X dumps, starting
with the oldest one, i.e. subsequent read will now return newer
dumps.

00ed1401a0 platform-msi: Add ABI to show msi_irqs of platform devices
PCI devices expose the associated MSI interrupts via sysfs, but platform
devices which utilize MSI interrupts do not. This information is important
for user space tools to optimize affinity settings.

Utilize the generic MSI sysfs facility to expose this information for

b25d5a1cd1 ACPI: platform-profile: call sysfs_notify() from platform_profile_store()
Drivers like thinkpad_acpi and ideapad_laptop call the
platform_profile_notify() helper when the profile is changed by hardware
(the embedded-controller/EC) in response to an EC handled hotkey.

This allows userspace to monitor for such changes by polling for POLLPRI
on the platform_profile sysfs file. But the profile can also be changed
underneath a userspace program monitoring it by anonther userspace program
storing a new value.

Add a sysfs_notify() call to platform_profile_store(), so that userspace
programs monitoring for changes also get notified in this case.

Also update the documentation to document that POLLPRI polling can be
used to watch for changes.

0f920277dc misc: gehc-achc: new driver
General Electric Healthcare's PPD has a secondary processor from
NXP's Kinetis K20 series. That device has two SPI chip selects:

The main interface's behaviour depends on the loaded firmware
and is currently unused.

The secondary interface can be used to update the firmware using
EzPort protocol. This is implemented by this driver using the
kernel's firmware API. The firmware is being flashed into
non-volatile flash memory, so it is enough to flash it once
and not on every boot. Flashing will wear the flash memory
(it has a life time of at least 10k programming cycles). At
the same time only occasional FW updates are expected (like e.g.
a BIOS update). Thus the firmware update is triggered via sysfs
instead of doing it in the driver's probe routine like many
other drivers.

7a6226db07 ACPI: DPTF: Add new PCH FIVR methods
Some additional information is required for updating PCH FIVR values
upon WiFi channel changes.

New attributes added to the existing sysfs:

fivr_switching_freq_mhz	: Get the FIVR switching control frequency.
			  Uses ACPI method GFCS.

fivr_switching_fault_status: Read the FIVR switching frequency control
			     fault status. Uses ACPI method GFFS.

ssc_clock_info : Presents SSC (spread spectrum clock) information for
		 EMI (Electro magnetic interference) control. Use ACPI
		 method GEMI (refer to the description of GEMI method
		 below).

GFFS
This ACPI method is used to read the FIVR switching frequency control
fault status.
Bits	Description
[0:0]	Fault status when set to 1
[31:1]	Reserved

GFCS
This ACPI method is used to read the FIVR switching control frequency.
Bits	Description
[11:0]	Actual Frequency = value * XTAL_FREQ / 128
[31:12]	Reserved

GEMI
This ACPI method is used to read the programmed register value for
EMI (Electro magnetic interference) control.

Bits	Description
[7:0]	Sets clock spectrum spread percentage:
	0x00=0.2% , 0x3F=10%
	1 LSB = 0.1% increase in spread (for
	settings 0x01 thru 0x1C)
	1 LSB = 0.2% increase in spread (for
	settings 0x1E thru 0x3F)
[8]	When set to 1, enables spread
	spectrum clock
[9]	0: Triangle mode. FFC frequency
	walks around the Fcenter in a linear
	fashion
	1: Random walk mode. FFC frequency
	changes randomly within the SSC
	(Spread spectrum clock) range
[10]	0: No white noise. 1: Add white noise
	to spread waveform
[11]	When 1, future writes are ignored.

227c4d507c f2fs-for-5.14-rc1
In this round, we've improved the compression support especially for Android
 such as allowing compression for mmap files, replacing the immutable bit with
 internal bit to prohibits data writes explicitly, and adding a mount option,
 "compress_cache", to improve random reads. And, we added "readonly" feature to
 compact the partition w/ compression enabled, which will be useful for Android
 RO partitions.
 
 Enhancement:
  - support compression for mmap file
  - use an f2fs flag instead of IMMUTABLE bit for compression
  - support RO feature w/ extent_cache
  - fully support swapfile with file pinning
  - improve atgc tunability
  - add nocompress extensions to unselect files for compression
 
 Bug fix:
  - fix false alaram on iget failure during GC
  - fix race condition on global pointers when there are multiple f2fs instances
  - add MODULE_SOFTDEP for initramfs
 
 As usual, we've also cleaned up some places for better code readability.

a16d8644ba Staging / IIO driver patches for 5.14-rc1
Here is the big set of IIO and staging driver patches for 5.14-rc1.
 
 Loads of IIO driver updates and additions in here, the shortlog has the
 full details.
 
 For the staging side, we moved a few drivers out of staging, and deleted
 the kpc2000 drivers as the original developer asked us to because no one
 was working on them anymore.
 
 Also in here are loads of coding style cleanups due to different intern
 projects focusing on the staging tree to try to get experience doing
 kernel development.
 
 All of these have been in the linux-next tree for a while with no
 reported problems.

Pull CXL (Compute Express Link) updates from Dan Williams:
 "This subsystem is still in the build-out phase as the bulk of the
  update is improvements to enumeration and fleshing out the device
  model. In terms of new features, more mailbox commands have been added
  to the allowed-list in support of persistent memory provisioning
  support targeting v5.15.

  The critical update from an enumeration perspective is support for the
  CXL Fixed Memory Window Structure that indicates to Linux which system
  physical address ranges decode to the CXL Host Bridges in the system.
  This allows the driver to detect which address ranges have been mapped
  by firmware and what address ranges are available for future hotplug.

  So, again, mostly skeleton this round, with more meat targeting v5.15.

  Summary:

   - Add support for the CXL Fixed Memory Window Structure, a recent
     extension of the ACPI CEDT (CXL Early Discovery Table)

   - Add infrastructure for component registers

   - Add HDM (Host-managed device memory) decoder definitions

   - Define a device model for an HDM decoder tree

   - Bridge CXL persistent memory capabilities to an NVDIMM bus /
     device-model

   - Switch to fine grained mapping of CXL MMIO registers to allow
     different drivers / system software to own individual register
     blocks

   - Enable media provisioning commands, and publish the label storage

bd31b9efbf SCSI misc on 20210702
This series consists of the usual driver updates (ufs, ibmvfc,
 megaraid_sas, lpfc, elx, mpi3mr, qedi, iscsi, storvsc, mpt3sas) with
 elx and mpi3mr being new drivers.  The major core change is a rework
 to drop the status byte handling macros and the old bit shifted
 definitions and the rest of the updates are minor fixes.

8053f2d752 perf/x86/intel/uncore: Add alias PMU name
A perf PMU may have two PMU names. For example, Intel Sapphire Rapids
server supports the discovery mechanism. Without the platform-specific
support, an uncore PMU is named by a type ID plus a box ID, e.g.,
uncore_type_0_0, because the real name of the uncore PMU cannot be
retrieved from the discovery table. With the platform-specific support
later, perf has the mapping information from a type ID to a specific
uncore unit. Just like the previous platforms, the uncore PMU is named
by the real PMU name, e.g., uncore_cha_0. The user scripts which work
well with the old numeric name may not work anymore.

Add a new attribute "alias" to indicate the old numeric name. The
following userspace perf tool patch will handle both names. The user
scripts should work properly with the updated perf tool.

73f37068d5 ptp: support ptp physical/virtual clocks conversion
Support ptp physical/virtual clocks conversion via sysfs.
There will be a new attribute n_vclocks under ptp physical
clock sysfs.

- In default, the value is 0 meaning only ptp physical clock
  is in use.
- Setting the value can create corresponding number of ptp
  virtual clocks to use. But current physical clock is guaranteed
  to stay free running.
- Setting the value back to 0 can delete virtual clocks and back
  use physical clock again.

Another new attribute max_vclocks control the maximum number of
ptp vclocks.

ed78f56e12 powerpc/papr_scm: Make 'perf_stats' invisible if perf-stats unavailable
In case performance stats for an nvdimm are not available, reading the
'perf_stats' sysfs file returns an -ENOENT error. A better approach is
to make the 'perf_stats' file entirely invisible to indicate that
performance stats for an nvdimm are unavailable.

So this patch updates 'papr_nd_attribute_group' to add a 'is_visible'
callback implemented as newly introduced 'papr_nd_attribute_visible()'
that returns an appropriate mode in case performance stats aren't
supported in a given nvdimm.

Also the initialization of 'papr_scm_priv.stat_buffer_len' is moved
from papr_scm_nvdimm_init() to papr_scm_probe() so that it value is
available when 'papr_nd_attribute_visible()' is called during nvdimm
initialization.

Even though 'perf_stats' attribute is available since v5.9, there are
no known user-space tools/scripts that are dependent on presence of its
sysfs file. Hence I dont expect any user-space breakage with this
patch.

Let's create /sys/fs/f2fs/<disk>/feature_list/ to meet sysfs rule.

Note that there are three feature list entries:
1) /sys/fs/f2fs/features
  : shows runtime features supported by in-kernel f2fs along with Kconfig.
    - ref. F2FS_FEATURE_RO_ATTR()

2) /sys/fs/f2fs/$s_id/features <deprecated>
  : shows on-disk features enabled by mkfs.f2fs, used for old kernels. This
    won't add new feature anymore, and thus, users should check entries in 3)
    instead of this 2).

3) /sys/fs/f2fs/$s_id/feature_list
  : shows on-disk features enabled by mkfs.f2fs per instance, which follows
    sysfs entry rule where each entry should expose single value.
    This list covers old feature list provided by 2) and beyond. Therefore,
    please add new on-disk feature in this list only.

8af9fa37b8 platform/x86: dell-privacy: Add support for Dell hardware privacy
add support for Dell privacy driver for the Dell units equipped
hardware privacy design, which protect users privacy of audio and
camera from hardware level. Once the audio or camera privacy mode
activated, any applications will not get any audio or video stream
when user pressed ctrl+F4 hotkey, audio privacy mode will be
enabled, micmute led will be also changed accordingly
The micmute led is fully controlled by hardware & EC(embedded controller)
and camera mute hotkey is Ctrl+F9. Currently design only emits
SW_CAMERA_LENS_COVER event while the camera lens shutter will be
changed by EC & HW(hardware) control

*The flow is like this:
1) User presses key. HW does stuff with this key (timeout timer is started)
2) WMI event is emitted from BIOS to kernel
3) WMI event is received by dell-privacy
4) KEY_MICMUTE emitted from dell-privacy
5) Userland picks up key and modifies kcontrol for SW mute
6) Codec kernel driver catches and calls ledtrig_audio_set
7) dell-privacy notifies EC, the timeout is cancelled and the HW mute
   is activated. If the EC is not notified then the HW mic mute will
   activate when the timeout triggers, just a bit later than with the
   active ack.

b4e326165e USB: misc: Add onboard_usb_hub driver
The main issue this driver addresses is that a USB hub needs to be
powered before it can be discovered. For discrete onboard hubs (an
example for such a hub is the Realtek RTS5411) this is often solved
by supplying the hub with an 'always-on' regulator, which is kind
of a hack. Some onboard hubs may require further initialization
steps, like changing the state of a GPIO or enabling a clock, which
requires even more hacks. This driver creates a platform device
representing the hub which performs the necessary initialization.
Currently it only supports switching on a single regulator, support
for multiple regulators or other actions can be added as needed.
Different initialization sequences can be supported based on the
compatible string.

Besides performing the initialization the driver can be configured
to power the hub off during system suspend. This can help to extend
battery life on battery powered devices which have no requirements
to keep the hub powered during suspend. The driver can also be
configured to leave the hub powered when a wakeup capable USB device
is connected when suspending, and power it off otherwise.

Technically the driver consists of two drivers, the platform driver
described above and a very thin USB driver that subclasses the
generic driver. The purpose of this driver is to provide the platform
driver with the USB devices corresponding to the hub(s) (a hub
controller may provide multiple 'logical' hubs, e.g. one to support
USB 2.0 and another for USB 3.x).

Note: the current series only supports hubs connected directly to
a root hub (through xhci-plat), support for other configurations
could be added if needed.

40ba17afdf cxl/acpi: Introduce cxl_decoder objects
A cxl_decoder is a child of a cxl_port. It represents a hardware decoder
configuration of an upstream port to one or more of its downstream
ports. The decoder is either represented in CXL standard HDM decoder
registers (see CXL 2.0 section 8.2.5.12 CXL HDM Decoder Capability
Structure), or it is a static decode configuration communicated by
platform firmware (see the CXL Early Discovery Table: Fixed Memory
Window Structure).

The firmware described and hardware described decoders differ slightly
leading to 2 different sub-types of decoders, cxl_decoder_root and
cxl_decoder_switch. At the root level the decode capabilities restrict
what can be mapped beneath them. Mid-level switch decoders are
configured for either acclerator (type-2) or memory-expander (type-3)
operation, but they are otherwise agnostic to the type of memory
(volatile vs persistent) being mapped.

Here is an example topology from a single-ported host-bridge environment
without CFMWS decodes enumerated.

7d4b5ca2e2 cxl/acpi: Add downstream port data to cxl_port instances
In preparation for infrastructure that enumerates and configures the CXL
decode mechanism of an upstream port to its downstream ports, add a
representation of a CXL downstream port.

On ACPI systems the top-most logical downstream ports in the hierarchy
are the host bridges (ACPI0016 devices) that decode the memory windows
described by the CXL Early Discovery Table Fixed Memory Window
Structures (CEDT.CFMWS).

4812be97c0 cxl/acpi: Introduce the root of a cxl_port topology
While CXL builds upon the PCI software model for enumeration and
endpoint control, a static platform component is required to bootstrap
the CXL memory layout. Similar to how ACPI identifies root-level PCI
memory resources, ACPI data enumerates the address space and interleave
configuration for CXL Memory.

In addition to identifying host bridges, ACPI is responsible for
enumerating the CXL memory space that can be addressed by downstream
decoders. This is similar to the requirement for ACPI to publish
resources via the _CRS method for PCI host bridges. Specifically, ACPI
publishes a table, CXL Early Discovery Table (CEDT), which includes a
list of CXL Memory resources, CXL Fixed Memory Window Structures
(CFMWS).

For now, introduce the core infrastructure for a cxl_port hierarchy
starting with a root level anchor represented by the ACPI0017 device.

Follow on changes model support for the configurable decode capabilities
of cxl_port instances, i.e. CXL switch support.
