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. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEE7TEboABC71LctBLFZR1NuKta54AFAmEvnt8ACgkQZR1NuKta 54B6GwgAgDZE/watviT5VzS/Cb5wXitOjLfq9eEOVqwD7+sT0c6PDSpIMiFnz4BV yCPttVAWJPgcQFde/6WXHz8kAsG1dMDQ6ClXHWwNyhxdjVuRAeoHjChlkoW3E0SW ZiSoWcQy6bCPmy0mfy6reZsJzO1IOokW0QpYVbQKbxaxS9TdVKhBIMWkALUPqQCz JfA2LEn4ZMbQIGdcm7gb5NI2xlBok94IKv3D5i9Isy3IyT1+yIYoncHZHDwBK6oV uhVvQK4it8i+wfEbxE1CHavPmXQXlvziIZNQ0TqlAOzncN4tc6a3mSdnJKcpinmS Gy93ceWgXxJDZbpTIXHB18lMg4z5yg== =I/ND -----END PGP SIGNATURE----- Merge tag 'misc-habanalabs-next-2021-09-01' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into char-misc-next Oded writes: 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.

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).

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.

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.

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 platform MSI.

NCQ priority is an optional feature of the NCQ feature set and should not be confused with the NCQ feature set itself.

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. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J.

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.

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.

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.

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.

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.

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. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

Networking changes for 5.14.
Core: - BPF: - add syscall program type and libbpf support for generating instructions and bindings for in-kernel BPF loaders (BPF loaders for BPF), this is a stepping stone for signed BPF programs - infrastructure to migrate TCP child sockets from one listener to another in the same reuseport group/map to improve flexibility of service hand-off/restart - add broadcast support to XDP redirect - allow bypass of the lockless qdisc to improving performance (for pktgen: +23% with one thread, +44% with 2 threads) - add a simpler version of "DO_ONCE()" which does not require jump labels, intended for slow-path usage - virtio/vsock: introduce SOCK_SEQPACKET support - add getsocketopt to retrieve netns cookie - ip: treat lowest address of a IPv4 subnet as ordinary unicast address allowing reclaiming of precious IPv4 addresses - ipv6: use prandom_u32() for ID generation - ip: add support for more flexible field selection for hashing across multi-path routes (w/ offload to mlxsw) - icmp: add support for extended RFC 8335 PROBE (ping) -

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.
Fixes:

f2fs: clean up /sys/fs/f2fs/<disk>/features
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. - ref.

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.

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.

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. /sys/bus/cxl/devices/root0 ├── devtype ├── dport0 -> ../../../LNXSYSTM:00/LNXSYBUS:00/ACPI0016:00 ├── port1 │ ├── decoder1.0 │ │ ├── devtype │ │ ├── locked │ │ ├── size │ │ ├── start │ │ ├── subsystem -> ../../../../../../bus/cxl │ │ ├── target_list │ │ ├── target_type │ │ └── uevent │ ├── devtype │ ├── dport0 -> ../../../../pci0000:34/0000:34:00.0 │ ├── subsystem -> ../../../../../bus/cxl │ ├── uevent │ └── uport -> ../../../../LNXSYSTM:00/LNXSYBUS:00/ACPI0016:00 ├── subsystem -> ../../../../bus/cxl ├── uevent └── uport -> ../../ACPI0017:00 Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Link: https://lore.kernel.org/r/162325695128.2293823.17519927266014762694.stgit@dwillia2-desk3.amr.corp.intel.com Signed-off-by: Dan Williams <dan.j.williams@intel.com> |

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).

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.
