ocxl: control via sysfs whether the FPGA is reloaded on a link reset
Some opencapi FPGA images allow to control if the FPGA should be reloaded on the next adapter reset. If it is supported, the image specifies it through a Vendor Specific DVSEC in the config space of function 0.

powerpc/papr_scm: Fetch nvdimm health information from PHYP
Implement support for fetching nvdimm health information via
H_SCM_HEALTH hcall as documented in Ref[1]. The hcall returns a pair
of 64-bit bitmap, bitwise-and of which is then stored in
'struct papr_scm_priv' and subsequently partially exposed to
user-space via newly introduced dimm specific attribute
'papr/flags'. Since the hcall is costly, the health information is
cached and only re-queried, 60s after the previous successful hcall.
The patch also adds a documentation text describing flags reported by
the the new sysfs attribute 'papr/flags' is also introduced at
Documentation/ABI/testing/sysfs-bus-papr-pmem.

Merge branch 'x86/srbds' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 srbds fixes from Thomas Gleixner:
"The 9th episode of the dime novel "The performance killer" with the
subtitle "Slow Randomizing Boosts Denial of Service".
SRBDS is an MDS-like speculative side channel that can leak bits from
the random number generator (RNG) across cores and threads. New
microcode serializes the processor access during the execution of
RDRAND and RDSEED. This ensures that the shared buffer is overwritten
before it is released for reuse. This is equivalent to a full bus
lock, which means that many threads running the RNG instructions in
parallel have the same effect as the same amount of threads issuing a
locked instruction targeting an address which requires locking of two
cachelines at once.
The mitigation support comes with the usual pile of unpleasant
ingredients:
- command line options
- sysfs file
- microcode checks
- a list of vulnerable CPUs identified by model and stepping this
time which requires stepping match support for the cpu match logic.
- the inevitable slowdown of affected CPUs"
* branch 'x86/srbds' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/speculation: Add Ivy Bridge to affected list

RDMA 5.8 merge window pull request
A few large, long discussed works this time. The RNBD block driver has
been posted for nearly two years now, and the removal of FMR has been a
recurring discussion theme for a long time. The usual smattering of
features and bug fixes.
- Various small driver bugs fixes in rxe, mlx5, hfi1, and efa
- Continuing driver cleanups in bnxt_re, hns
- Big cleanup of mlx5 QP creation flows
- More consistent use of src port and flow label when LAG is used and a
mlx5 implementation
- Additional set of cleanups for IB CM
- 'RNBD' network block driver and target. This is a network block RDMA
device specific to ionos's cloud environment. It brings strong multipath
and resiliency capabilities.
- Accelerated IPoIB for HFI1
- QP/WQ/SRQ ioctl migration for uverbs, and support for multiple async fds
- Support for exchanging the new IBTA defiend ECE data during RDMA CM
exchanges
- Removal of the very old and insecure FMR interface from all ULPs and
drivers. FRWR should be preferred for at least a decade now.

- Various small driver bugs fixes in rxe, mlx5, hfi1, and efa
- Continuing driver cleanups in bnxt_re, hns
- Big cleanup of mlx5 QP creation flows
- More consistent use of src port and flow label when LAG is used and
a mlx5 implementation
- Additional set of cleanups for IB CM
- 'RNBD' network block driver and target. This is a network block
RDMA device specific to ionos's cloud environment. It brings strong
multipath and resiliency capabilities.
- Accelerated IPoIB for HFI1
- QP/WQ/SRQ ioctl migration for uverbs, and support for multiple
async fds
- Support for exchanging the new IBTA defiend ECE data during RDMA CM
exchanges
- Removal of the very old and insecure FMR interface from all ULPs
and drivers. FRWR should be preferred for at least a decade now"

powerpc updates for 5.8
- Support for userspace to send requests directly to the on-chip GZIP
accelerator on Power9.
- Rework of our lockless page table walking (__find_linux_pte()) to make it
safe against parallel page table manipulations without relying on an IPI for
serialisation.
- A series of fixes & enhancements to make our machine check handling more
robust.
- Lots of plumbing to add support for "prefixed" (64-bit) instructions on
Power10.
- Support for using huge pages for the linear mapping on 8xx (32-bit).
- Remove obsolete Xilinx PPC405/PPC440 support, and an associated sound driver.
- Removal of some obsolete 40x platforms and associated cruft.
- Initial support for booting on Power10.

Power management updates for 5.8-rc1
- Rework the system-wide PM driver flags to make them easier to
understand and use and update their documentation (Rafael Wysocki,
Alan Stern).
- Allow cpuidle governors to be switched at run time regardless of
the kernel configuration and update the related documentation
accordingly (Hanjun Guo).
- Improve the resume device handling in the user space hibernarion
interface code (Domenico Andreoli).
- Document the intel-speed-select sysfs interface (Srinivas
Pandruvada).
- Make the ACPI code handing suspend to idle print more debug
messages to help diagnose issues with it (Rafael Wysocki).
- Fix a helper routine in the cpufreq core and correct a typo in
the struct cpufreq_driver kerneldoc comment (Rafael Wysocki, Wang
Wenhu).
- Update cpufreq drivers:
* Make the intel_pstate driver start in the passive mode by
default on systems without HWP (Rafael Wysocki).
* Add i.MX7ULP support to the imx-cpufreq-dt driver and add
i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).

A fair amount of stuff this time around, dominated by yet another massive
set from Mauro toward the completion of the RST conversion. I *really* hope we are getting close to the end of this. Meanwhile, those patches reach pretty far afield to update document references around the tree; there should be no actual code changes there. There will be, alas, more of the usual trivial merge conflicts. Beyond that we have more translations, improvements to the sphinx scripting, a number of additions to the sysctl documentation, and lots of fixes. -----BEGIN PGP SIGNATURE----- iQFDBAABCAAtFiEEIw+MvkEiF49krdp9F0NaE2wMflgFAl7VId8PHGNvcmJldEBs d24ubmV0AAoJEBdDWhNsDH5Yq/gH/iaDgirQZV6UZ2v9sfwQNYolNpf2sKAuOZjd bPFB7WJoMQbKwQEvYrAUL2+5zPOcLYuIfzyOfo1BV1py+EyKbACcKjI4AedxfJF7 +NchmOBhlEqmEhzx2U08HRc4/8J223WG17fJRVsV3p+opJySexSFeQucfOciX5NR RUCxweWWyg/FgyqjkyMMTtsePqZPmcT5dWTlVXISlbWzcv5NFhuJXnSrw8Sfzcmm SJMzqItv3O+CabnKQ8kMLV2PozXTMfjeWH47ZUK0Y8/8PP9+cvqwFzZ0UDQJ1Xaz oyW/TqmunaXhfMsMFeFGSwtfgwRHvXdxkQdtwNHvo1dV4dzTvDw= =fDC/ -----END PGP SIGNATURE----- Merge tag 'docs-5.8' of git://git.lwn.net/linux Pull documentation updates from Jonathan Corbet: "A fair amount of stuff this time around, dominated by yet another massive set from Mauro toward the completion of the RST conversion.

ACPI: DPTF: Add battery participant driver
This driver adds support for Dynamic Platform and Thermal Framework battery participant device support. These attributes are presented via sysfs interface under the platform device for the battery participant: $ls /sys/bus/platform/devices/INT3532:00/dptf_battery current_discharge_capbility_ma max_platform_power_mw no_load_voltage_mv high_freq_impedance_mohm max_steady_state_power_mw Refer to the documentation at Documentation/ABI/testing/sysfs-platform-dptf for details. Here the implementation reuses existing dptf-power.c as the motivation and processing is same. It also shares one ACPI method. Here this change is using participant type, "PTYP" method to identify and do different processing. By using participant type, create/delete either "dptf_power" or "dptf_battery" attribute group and send notifications. The particpant type for for the battery participant is 0x0C. ACPI methods description: PMAX (Intel(R) Dynamic Tuning Platform Max Power Supplied by Battery): This object evaluates to the maximum platform power that can be supported by the battery in milli watts. PBSS (Intel(R) Dynamic Tuning Power Battery Steady State): This object returns the max sustained power for battery in milli watts. RBHF (Intel(R) Dynamic Tuning High Frequency Impedance): This object returns high frequency impedance value that can be obtained from battery fuel gauge. VBNL (Intel(R) Dynamic Tuning No-Load Voltage) This object returns battery instantaneous no-load voltage that can be obtained from battery fuel gauge in milli volts CMPP (Intel(R) Dynamic Tuning Current Discharge Capability) This object returns battery discharge current capability obtained from battery fuel gauge milli amps.

ACPI: DPTF: Additional sysfs attributes for power participant driver
Add two additional attributes to the existing power participant driver:
rest_of_platform_power_mw: (RO) Shows the rest of worst case platform
power in mW outside of S0C. This will help in power distribution to SoC
and rest of the system. For example on a test system, this value is 2.5W
with a 15W TDP SoC. Based on the adapter rating (adapter_rating_mw), user
space software can decide on proper power allocation to SoC to improve
short term performance via powercap/RAPL interface.
prochot_confirm: (WO) Confirm EC about a prochot notification.
Also userspace is notified via sysfs_notify(), whenever power source or
rest of the platform power is changed. So user space can use poll()
system call on those attributes.
The ACPI methods used in this patch are as follows:
PROP
This object evaluates to the rest of worst case platform power in mW.
Bits:
23:0 Worst case rest of platform power in mW.
PBOK
PBOK is a method designed to provide a mechanism for OSPM to change power
setting before EC can de-assert a PROCHOT from a device. The EC may
receive several PROCHOTs, so it has a sequence number attached to PSRC
(read via existing attribute "platform_power_source"). Once OSPM takes
action for a PSRC change notification, it can call PBOK method to confirm
with the sequence number.
Bits:
3:0 Power Delivery State Change Sequence number
30 Reserved
31 0 – Not OK to de-assert PROCHOT
1 – OK to de-assert PROCHOT
PSRC (Platform Power Source): Not new in this patch but for
documentation for new bits
This object evaluates to an integer that represents the system power
source as well as the power delivery state change sequence number.
Bits:
3:0 The current power source as an integer for AC, DC, USB, Wireless.
0 = DC, 1 = AC, 2 = USB, 3 = Wireless Charging
7:4 Power Delivery State Change Sequence Number. Default value is 0
Notifications:
0x81: (Power State Change) Used to notify when the power source has
changed.
0x84: (PROP change) Used to notify when the platform rest of power has
changed.

kernel/printk: add kmsg SEEK_CUR handling
Userspace libraries, e.g. glibc's dprintf(), perform a SEEK_CUR operation
over any file descriptor requested to make sure the current position isn't
pointing to junk due to previous manipulation of that same fd. And whenever
that fd doesn't have support for such operation, the userspace code expects
-ESPIPE to be returned.
However, when the fd in question references the /dev/kmsg interface, the
current kernel code state returns -EINVAL instead, causing an unexpected
behavior in userspace: in the case of glibc, when -ESPIPE is returned it
gets ignored and the call completes successfully, while returning -EINVAL
forces dprintf to fail without performing any action over that fd:
if (_IO_SEEKOFF (fp, (off64_t)0, _IO_seek_cur, _IOS_INPUT|_IOS_OUTPUT) ==
_IO_pos_BAD && errno != ESPIPE)
return NULL;
With this patch we make sure to return the correct value when SEEK_CUR is
requested over kmsg and also add some kernel doc information to formalize
this behavior.

Expose MIPI DisCo Slave properties in sysfs. For Slave properties and Data Port 0, the attributes are managed with simple devm_ support. A Slave Device may have more than one Data Port (DPN), and each Data Port can be sink or source. The attributes are created dynamically using pre-canned macros, but still use devm_ with a name attribute group to avoid creating kobjects - as requested by GregKH. In the _show function, we use container_of() to retrieve port number and direction required to extract the information. Audio modes are not supported for now.

In Gaudi there is a feature of clock gating certain engines. Therefore, add this property to the device structure. In addition, due to a limitation of this feature, the driver needs to dynamically enable or disable this feature during run-time. Therefore, add ASIC interface functions to enable/disable this function from the common code. Moreover, this feature must be turned off when the user wishes to debug the ASIC by reading/writing registers and/or memory through the driver's debugfs. Therefore, add an option to enable/disable clock gating via the debugfs interface. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> |

w1_therm: adding bulk read support to trigger multiple conversion on bus
Adding bulk read support:
Sending a 'trigger' command in the dedicated sysfs entry of bus master
device send a conversion command for all the slaves on the bus. The sysfs
entry is added as soon as at least one device supporting this feature
is detected on the bus.
The behavior of the sysfs reading temperature on the device is as follow:
* If no bulk read pending, trigger a conversion on the device, wait for
the conversion to be done, read the temperature in device RAM
* If a bulk read has been trigger, access directly the device RAM
This behavior is the same on the 2 sysfs entries ('temperature' and
'w1_slave').
Reading the therm_bulk_read sysfs give the status of bulk operations:
* '-1': conversion in progress on at least 1 sensor
* '1': conversion complete but at least one sensor has not been read yet
* '0': no bulk operation. Reading temperature on ecah device will trigger
a conversion
As not all devices support bulk read feature, it has been added in device
family structure.
The attribute is set at master level as soon as a supporting device is
discover. It is removed when the last supported device leave the bus.
The count of supported device is kept with the static counter
bulk_read_device_counter.
A strong pull up is apply on the line if at least one device required it.
The duration of the pull up is the max time required by a device on the
line, which depends on the resolution settings of each device. The strong
pull up could be adjust with the a module parameter.
Updating documentation in Documentation/ABI/testing/sysfs-driver-w1_therm
and Documentation/w1/slaves/w1_therm.rst accordingly.

As alarms temperature level are store in a 8 bit register on the device and are signed values, a safe cast shall be performed using the min and max temperature that device are able to measure. This is done by int_to_short inline function. A 'write_data' field is added in the device structure, to bind the correct writing function, as some devices may have 2 or 3 bytes RAM.

w1_therm: optimizing temperature read timings
Optimizing temperature reading by reducing waiting conversion time according to device resolution settings, as per device specification. This is device dependent as not all the devices supports resolution setting, so it has been added in device family structures. The process to read the temperature on the device has been adapted in a new function 'convert_t()', which replace the former 'read_therm()', is introduce to deal with this timing. Strong pull up is also applied during the required time, according to device power status needs and 'strong_pullup' module parameter. 'temperature_from_RAM()' function is introduced to get the correct temperature computation (device dependent) from device RAM data. An new sysfs entry has been added to ouptut only temperature. The old entry w1_slave has been kept for compatibility, without changing its output format. Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

w1_therm: adding eeprom sysfs entry
The driver implement 2 hardware functions to access device RAM: * copy_scratchpad * recall_scratchpad They act according to device specifications. As EEPROM operations are not device dependent (all w1_therm can perform EEPROM read/write operation following the same protocol), it is removed from device families structures. Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

w1_therm: adding resolution sysfs entry
Adding resolution sysfs entry (RW) to get or set the device resolution Write values are managed as follow: * '9..12': resolution to set in bit * Anything else: do nothing Read values are : * '9..12': device resolution in bit * '-xx': xx is kernel error when reading the resolution Only supported devices will show the sysfs entry. A new family has been created for DS18S20 devices as they do not implement resolution feature. The resolution of each device is check when the device is discover by the bus master, in 'w1_therm_add_slave(struct w1_slave *)'. The status is stored in the device structure w1_therm_family_data so that the driver always knows the resolution of each device, which could be used later to determine the required conversion duration (resolution dependent). The resolution is re evaluate each time a user read or write the sysfs entry. To avoid looping through the w1_therm_families at run time, the pointer 'specific_functions' is set up to the correct 'w1_therm_family_converter' when the slave is added (which mean when it is discovered by the master). This initialization is done by a helper function 'device_family(struct w1_slave *sl)', and a dedicated macro 'SLAVE_SPECIFIC_FUNC(sl)' allow the access to the specific function of the slave device. 'read_scratchpad' and 'write_scratchpad' are the hardware functions to access the device RAM, as per protocol specification. It cancel the former 'precision' functions, which was only set and never read (so not stored in the device struct). Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

w1_therm: adding ext_power sysfs entry
Adding ext_power sysfs entry (RO). Return the power status of the device: - 0: device parasite powered - 1: device externally powered - xx: xx is kernel error The power status of each device is check when the device is discover by the bus master, in 'w1_therm_add_slave(struct w1_slave *)'. The status is stored in the device structure w1_therm_family_data so that the driver always knows the power state of each device, which could be used later to determine the required strong pull up to apply on the line. The power status is re evaluate each time the sysfs ext_power read by a user. The hardware function 'read_powermode(struct w1_slave *sl)' act just as per device specifications, sending W1_READ_PSUPPLY command on the bus, and issue a read time slot, reading only one bit. A helper function 'bool bus_mutex_lock(struct mutex *lock)' is introduced. It try to aquire the bus mutex several times (W1_THERM_MAX_TRY), waiting W1_THERM_RETRY_DELAY between two attempt.
