git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Heiko Carstens: - fix buffer size for in-kernel disassembler for ebpf programs. - fix two memory leaks in zcrypt driver. - expose PCI device UID as index, including an indicator if the uid is unique. - remove some oprofile leftovers. - improve stack unwinder tests. - don't use gcc atomic builtins anymore, just like all other architectures. Even though I'm sure the current code is ok, I totally dislike that s390 is the only architecture being special here; especially considering that there was a lengthly discussion about this topic and the outcome was not to use the builtins. Therefore open-code atomic ops again with inline assembly and switch to gcc builtins as soon as other architectures are doing. - couple of other changes to atomic and cmpxchg, and use atomic-instrumented.h for KASAN. - separate zbus creation, registration, and scanning in our PCI code which allows for cleaner and easier handling. - a rather large change to the vfio-ap code to fix circular locking dependencies when updating crypto masks. - move QAOB handling from qdio layer down to drivers. - add CRW inject facility to common I/O layer. This adds debugs files which allow to generate artificial events from user space for testing purposes. - increase SCLP console line length from 80 to 320 characters to avoid odd wrapped lines. - add protected virtualization guest and host indication files, which indicate either that a guest is running in pv mode or if the hypervisor is capable of starting pv guests. - various other small fixes and improvements all over the place. * tag 's390-5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (53 commits) s390/disassembler: increase ebpf disasm buffer size s390/archrandom: add parameter check for s390_arch_random_generate s390/zcrypt: fix zcard and zqueue hot-unplug memleak s390/pci: expose a PCI device's UID as its index s390/atomic,cmpxchg: always inline __xchg/__cmpxchg s390/smp: fix do_restart() prototype s390: get rid of oprofile leftovers s390/atomic,cmpxchg: make constraints work with old compilers s390/test_unwind: print test suite start/end info s390/cmpxchg: use unsigned long values instead of void pointers s390/test_unwind: add WARN if tests failed s390/test_unwind: unify error handling paths s390: update defconfigs s390/spinlock: use R constraint in inline assembly s390/atomic,cmpxchg: switch to use atomic-instrumented.h s390/cmpxchg: get rid of gcc atomic builtins s390/atomic: get rid of gcc atomic builtins s390/atomic: use proper constraints s390/atomic: move remaining inline assemblies to atomic_ops.h s390/bitops: make bitops only work on longs ...

Fix typos in the s5pv210 cpufreq driver (Bhaskar Chowdhury). - Fix cpufreq documentation links in Kconfig (Alexander Monakov). - Fix PCI device power state handling in pci_enable_device_flags() to avoid issuse in some cases when the device depends on an ACPI power resource (Rafael Wysocki). - Add missing documentation of pm_runtime_resume_and_get() (Alan Stern). - Add missing static inline stub for pm_runtime_has_no_callbacks() to pm_runtime.h and drop the unused try_to_freeze_nowarn() definition (YueHaibing). - Drop duplicate struct device declaration from pm.h and fix a structure type declaration in intel_rapl.h (Wan Jiabing). - Use dev_set_name() instead of an open-coded equivalent of it in the wakeup sources code and drop a redundant local variable initialization from it (Andy Shevchenko, Colin Ian King). - Use crc32 instead of md5 for e820 memory map integrity check during resume from hibernation on x86 (Chris von Recklinghausen). - Fix typos in comments in the system-wide and hibernation support code (Lu Jialin). - Modify the generic power domains (genpd) code to avoid resuming devices in the "prepare" phase of system-wide suspend and hibernation (Ulf Hansson). - Add Hygon Fam18h RAPL support to the intel_rapl power capping driver (Pu Wen). - Add MAINTAINERS entry for the dynamic thermal power management (DTPM) code (Daniel Lezcano). - Add devm variants of operating performance points (OPP) API functions and switch over some users of the OPP framework to the new resource-managed API (Yangtao Li and Dmitry Osipenko). - Update devfreq core: * Register devfreq devices as cooling devices on demand (Daniel Lezcano). * Add missing unlock opeation in devfreq_add_device() (Lukasz Luba). * Use the next frequency as resume_freq instead of the previous frequency when using the opp-suspend property (Dong Aisheng). * Check get_dev_status in devfreq_update_stats() (Dong Aisheng). * Fix set_freq path for the userspace governor in Kconfig (Dong Aisheng). * Remove invalid description of get_target_freq() (Dong Aisheng). -

Lots of little churn in here, and some larger churn as well. Major things are: - removal of wimax drivers, no one has this hardware anymore for this failed "experiment". - removal of the Google gasket driver, turns out no one wanted to maintain it or cares about it anymore, so they asked for it to be removed. - comedi finally moves out of the staging directory into drivers/comedi This is one of the oldest kernel subsystems around, being created in the 2.0 kernel days, and was one of the first things added to drivers/staging/ when that was created over 15 years ago. It should have been moved out of staging a long time ago, it's well maintained and used by loads of different devices in the real world every day. Nice to see this finally happen. - so many tiny coding style cleanups it's not funny. Perfect storm of at least 2 different intern project application deadlines combined to provide a huge number of new contributions in this area from people learning how to do kernel development.

2021-04-20s390/pci: expose a PCI device's UID as its indexNiklas Schnelle1-4/+7
On s390 each PCI device has a user-defined ID (UID) exposed under /sys/bus/pci/devices/<dev>/uid. This ID was designed to serve as the PCI device's primary index and to match the device within Linux to the device configured in the hypervisor. To serve as a primary identifier the UID must be unique within the Linux instance, this is guaranteed by the platform if and only if the UID Uniqueness Checking flag is set within the CLP List PCI Functions response. In this sense the UID serves an analogous function as the SMBIOS instance number or ACPI index exposed as the "index" respectively "acpi_index" device attributes and used by e.g. systemd to set interface names. As s390 does not use and will likely never use ACPI nor SMBIOS there is no conflict and we can just expose the UID under the "index" attribute whenever UID Uniqueness Checking is active and get systemd's interface naming support for free.

2021-04-13platform/x86: intel_pmc_core: export platform global reset bits via etr3 ↵Tamar Mashiah1-0/+20
sysfs file During PCH (platform/board) manufacturing process a global platform reset has to be induced in order for the configuration changes take the effect upon following platform reset. This is an internal platform state and is not intended to be used in the regular platform resets. The setting is exposed via ETR3 (Extended Test Mode Register 3). After the manufacturing process is completed the register cannot be written anymore and is hardware locked. This setting was commonly done by accessing PMC registers via /dev/mem but due to security concerns /dev/mem access is much more restricted, hence the reason for exposing this setting via the dedicated sysfs interface. To prevent post manufacturing abuse the register is protected by hardware locking and the file is set to read-only mode via is_visible handler. The register in MMIO space is defined for Cannon Lake and newer PCHs.

2021-04-09habanalabs/gaudi: add debugfs to DMA from the deviceOded Gabbay1-15/+53
When trying to debug program, the user often needs to dump large parts of the device's DRAM, which can reach to tens of GBs. Because reading from the device's internal memory through the PCI BAR is extremely slow, the debug can take hours. Instead, we can provide the user to copy data through one of the DMA engines. This will make the operation much faster. Currently, only GAUDI is supported. In GAUDI, we need to find a PCI DMA engine that is IDLE and set the DMA as secured to be able to bypass our MMU as we currently don't map the temporary buffer to the MMU. Example bash one-line to dump entire HBM to file (~2 minutes): for (( i=0x0; i < 0x800000000; i+=0x8000000 )); do \ printf '0x%x\n' $i | sudo tee /sys/kernel/debug/habanalabs/hl0/addr ; \ echo 0x8000000 | sudo tee /sys/kernel/debug/habanalabs/hl0/dma_size ; \ sudo cat /sys/kernel/debug/habanalabs/hl0/data_dma >> hbm.txt ; done Signed-off-by: Oded Gabbay <ogabbay@kernel.org>

2021-04-08power: supply: Add battery driver for Surface Aggregator ModuleMaximilian Luz1-0/+15
On newer Microsoft Surface models (specifically 7th-generation, i.e. Surface Pro 7, Surface Book 3, Surface Laptop 3, and Surface Laptop Go), battery and AC status/information is no longer handled via standard ACPI devices, but instead directly via the Surface System Aggregator Module (SSAM), i.e. the embedded controller on those devices. While on previous generation models, battery status is also handled via SSAM, an ACPI shim was present to translate the standard ACPI battery interface to SSAM requests. The SSAM interface itself, which is modeled closely after the ACPI interface, has not changed. This commit introduces a new SSAM client device driver to support battery status/information via the aforementioned interface on said Surface models. It is in parts based on the standard ACPI battery driver. Signed-off-by: Maximilian Luz <luzmaximilian@gmail.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>

2021-04-04PCI/IOV: Add sysfs MSI-X vector assignment interfaceLeon Romanovsky1-0/+29
A typical cloud provider SR-IOV use case is to create many VFs for use by guest VMs. The VFs may not be assigned to a VM until a customer requests a VM of a certain size, e.g., number of CPUs. A VF may need MSI-X vectors proportional to the number of CPUs in the VM, but there is no standard way to change the number of MSI-X vectors supported by a VF. Some Mellanox ConnectX devices support dynamic assignment of MSI-X vectors to SR-IOV VFs. This can be done by the PF driver after VFs are enabled, and it can be done without affecting VFs that are already in use. The hardware supports a limited pool of MSI-X vectors that can be assigned to the PF or to individual VFs. This is device-specific behavior that requires support in the PF driver. Add a read-only "sriov_vf_total_msix" sysfs file for the PF and a writable "sriov_vf_msix_count" file for each VF. Management software may use these to learn how many MSI-X vectors are available and to dynamically assign them to VFs before the VFs are passed through to a VM. If the PF driver implements the ->sriov_get_vf_total_msix() callback, "sriov_vf_total_msix" contains the total number of MSI-X vectors available for distribution among VFs. If no driver is bound to the VF, writing "N" to "sriov_vf_msix_count" uses the PF driver ->sriov_set_msix_vec_count() callback to assign "N" MSI-X vectors to the VF. When a VF driver subsequently reads the MSI-X Message Control register, it will see the new Table Size "N".

This includes providing a new directory per buffer that combines what was previously in buffer/ and scan_elements/. Old interfaces still in place for compatiblity. Note immuatable branch for scmi patches to allow for some significant rework going on in that subsystem. Merge required updating to reflect some changes in IIO. Late rebase to fix some wrong fixes tags due to some earlier rebases made necessary by messing up the immutable branch. IIO New Device Support * adi,ad5686 - Add info to support AD5673R and AD5677R * bosch,bmi088 - New driver supporting this accelerometer + gyroscope * cros_ec_mkbp - New driver for this proximity sensor that exposes a 'front' sensor. Very simple switch like device, but driver allows it to share interface with more sophisticated proximity sensors. * iio_scmi - New driver to support ARM SCMI protocol to expose underlying accelerometers and gyroscopes via this firmware interface. * st,st_magn - Add ID for IISMDC magnetometer. * ti,ads131e0 - New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs Counter New Device Support * IRQ or GPIO based counter - New driver for a conceptually simple counter that uses interrupts to perform the count. Features * core - Dual buffer supprt including: Various helpers to centralize handling of bufferer related elements. Document existing and new IOCTLs Register the IIO chrdev only if it can actually be used for anything. Rework attribute group creation in the core (lots of patches) Merge buffer/ and scan_elements/ entries into one list + maintain backwards compatible set. Introduce the internal logic and IOCTL to allow multiple buffers + access to an anon FD per buffer to actually read from it. Tidy up tools/iio/iio_generic_buffer and switch to new interfaces. Update ABI docs. A few follow up fixes, unsuprising as this was a huge bit of rework. - Move common case setting of trig->parent to the core. - Provide an iio_read_channel_processed_scale() to avoid loss of precision from iio_read_channel_processed() then applying integer scale. Use it in ntc_thermistor driver in hwmon. - Allow drivers to specify labels from elsewhere than DT. Use it for bmc150 and kxcjk-1013 labels related to position on 2 in one tablets. - Document label usage for proximity and accelerometer sensors. - Some local variable renames for consistency tools - Add -a parameter to iio_event_monitor to allow autoenabling of events. * acpi_als - Add trigger support for devices that don't support notification method. * adi,ad7124 - Allow more than 8 channels. This is a complex little device, but is capable of supporting up to 16 channels if the share certain configuration settings. * hrtimer-trigger - Support sampling frequency below 1Hz. * mediatek,mt8195-auxadc - Add compatible to binding docs (always also includes mt8173) * st,stm32-adc - Enable timetamps when not using DMA. * vishay,vcnl3020 - Sampling frequency control. Cleanup and minor fixes: * treewide - Use some getter and setter functions instead of opencoding. - Set of fixes for pointless casts in various drivers. - Avoid wrong kernel-doc marking on comment blocks. - Fix various other minor kernel-doc issues shown by W=1 * core - Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts. - Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0 - Add unit tests for iio_format_value() * docs - Fix formatting/typos in iio_configfs.rst and buffers.rst - Add documentation of index in buffers.rst - Fix scan element description - Avoid some issues with HTML generation from ABI docs by moving duplicated defintions to more generic files. - Drop reference to long dead mailing list. * 104-quad - Remove left over deprecated IIO counter ABI. * adi,adi-axi-adc - Fix wrong bit of docs. * adi,ad5791 - Typos * adi,ad9834 - Switch to device managed functions in probe. * adi,adis* - Add and use helpers for locking to reduced duplication. * adi,adis16480 - Fix calculation of sampling frequency when using pulse per second input. * adi,adis16475 - Calculate the IMU scaled internal sampling rate and runtime depending on sysfs based configuration rather than getting from DT. Drop now unnecessary property from DT bindings doc. * cros_ec - Fix result of a series of recent changes that means extended buffer attributes turn up in the wrong place.

2021-03-18thunderbolt: Add support for maxhopid XDomain propertyMika Westerberg1-0/+7
USB4 inter-domain spec mandates that the compatible hosts expose a new property "maxhopid" that tells the connection manager on the other side what is the maximum supported input HopID over the connection. Since this is depend on the lane adapter the cable is connected it needs to be filled in dynamically. For this reason we take a copy of the global properties and fill then for each XDomain connection upon first connect, and then keep updating it if the generation changes as services are being added/removed. We also take advantage of this copy to fill in the hostname. We also expose this maxhopid as an attribute under each XDomain device. While there drop kernel-doc entry for property_lock which seems to be left there when the structure was originally introduced. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

Since the new change to the IIO buffer infrastructure, the buffer/ and scan_elements/ directories have been merged into bufferY/ to have some attributes available per-buffer. This change updates the ABI docs to reflect this change. The hwfifo attributes are not updated, as for now these should be used via the legacy buffer/ directory until they are moved into core.

2021-03-11iio: documentation: Document accelerometer label useHans de Goede1-0/+7
Some 2-in-1 laptops / convertibles with 360° (yoga-style) hinges, have 2 accelerometers, 1 in their base and 1 in their display. In many cases the kernel can detect the location of each accelerometer based on e.g. information from the ACPI tables. It is important for userspace to know the location of the 2 accelerometers. Rather then adding a new sysfs-attribute for this we can relay this information to userspace by using standardized label strings for this. This mirrors how this is done for proximity sensors. This commit documents 2 new standardized label strings for this purpose: "accel-base" "accel-display" Note the "base" and "display" suffixes were chosen to match the values used for the systemd/udev hwdb.d/60-sensor.hwdb file's ACCEL_LOCATION property.

2021-03-11iio: documentation: Document proximity sensor label useHans de Goede1-0/+39
Add an entry to Documentation/ABI/testing/sysfs-bus-iio for the new device label sysfs-attribute support. And document the standardized labels which may be used with proximity sensors to hint userspace about the intended use of the sensor. Using labels to differentiate between the multiple proximity sensors which a modern laptop/tablet may have was discussed in this thread: https://lore.kernel.org/linux-iio/9f9b0ff6-3bf1-63c4-eb36-901cecd7c4d9@redhat.com/ As mentioned there the "proximity-wifi*" labels are already being used in this manner on some chromebooks, see e.g.: arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi arch/arm64/boot/dts/qcom/sc7180-trogdor-lte-sku.dtsi And the "proximity-palmrest" and "proximity-lap" labels are intended to be used with the lap and palmrest sensors found in recent Lenovo ThinkPad models.
