The SMpro co-processor on Ampere Altra processor family is to monitor
and report various data included hwmon-related info, RAS errors, and
other miscellaneous information. The SMPro MFD driver initializes the
register map and instantiates all sub-devices. All the specifics will
be handled in the child drivers.
This patch set includes support for Ampere SMpro hwmon, errmon, and
misc as the child drivers. The hwmon driver supports accessing various
CPU sensors provided by the SMpro co-processor including temperature,
power, voltages, and current found on Ampere Altra processor family.
The errmon driver supports monitoring and reporting RAS-related errors.
The misc driver is to support reporting boot progress and other
miscellaneous information.

+Kernel driver Ampere(R)'s Altra(R) SMpro hwmon
+==============================================
+
+Supported chips:
+
+ * Ampere(R) Altra(R)
+
+ Prefix: 'smpro'
+
+ Reference: Altra SoC BMC Interface Specification
+
+Author: Thu Nguyen <thu@os.amperecomputing.com>
+
+Description
+-----------
+This driver supports hardware monitoring for Ampere(R) Altra(R) SoC's based on the
+SMpro co-processor (SMpro).
+The following sensor types are supported by the driver:
+
+ * temperature
+ * voltage
+ * current
+ * power
+
+The SMpro interface provides the registers to query the various sensors and
+their values which are then exported to userspace by this driver.
+
+Usage Notes
+-----------
+
+SMpro hwmon driver creates at least two sysfs files for each sensor.
+
+* File ``<sensor_type><idx>_label`` reports the sensor label.
+* File ``<sensor_type><idx>_input`` returns the sensor value.
+
+The sysfs files are allocated in the SMpro root fs folder.
+There is one root folder for each SMpro instance.
+
+When the SoC is turned off, the driver will fail to read registers
+and return -ENXIO.
+
+Sysfs entries
+-------------
+
+The following sysfs files are supported:
+
+* Ampere(R) Altra(R):

+Kernel driver Ampere(R)'s Altra(R) SMpro errmon
+===============================================
+
+Supported chips:
+
+ * Ampere(R) Altra(R)
+
+ Prefix: 'smpro'
+
+ Preference: Altra SoC BMC Interface Specification
+
+Author: Thu Nguyen <thu@os.amperecomputing.com>
+
+Description
+-----------
+
+This driver supports hardware monitoring for Ampere(R) Altra(R) SoC's based on the
+SMpro co-processor (SMpro).
+The following SoC alert/event types are supported by the errmon driver:
+
+* Core CE/UE error
+* Memory CE/UE error
+* PCIe CE/UE error
+* Other CE/UE error
+* Internal SMpro/PMpro error
+* VRD hot
+* VRD warn/fault
+* DIMM Hot
+
+The SMpro interface provides the registers to query the status of the SoC alerts/events
+and their data and export to userspace by this driver.
+
+The SoC alerts/events will be referenced as error below.
+
+Usage Notes
+-----------
+
+SMpro errmon driver creates the sysfs files for each error type.
+Example: ``error_core_ce`` to get Core CE error type.
+
+* If the error is absented, the sysfs file returns empty.
+* If the errors are presented, one each read to the sysfs, the oldest error will be returned and clear, the next read will be returned with the next error until all the errors are read out.
+
+For each host error type, SMpro keeps a latest max number of errors. All the oldest errors that were not read out will be dropped. In that case, the read to the corresponding overflow sysfs will return 1, otherwise, return 0.
+Example: ``overflow_core_ce`` to report the overflow status of Core CE error type.
+
+The format of the error is depended on the error type.
+
+1) For Core/Memory/PCIe/Other CE/UE error types::
+
+The return 48-byte in hex format in table below:
+
+ ======= ============= =========== ==========================================
+ OFFSET FIELD SIZE (BYTE) DESCRIPTION

+Kernel driver Ampere(R) Altra(R) SMpro miscellaneous
+====================================================
+
+Supported chips:
+
+ * Ampere(R) Altra(R)
+
+ Prefix: 'smpro'
+
+ Reference: Altra SoC BMC Interface Specification
+
+Author: Thu Nguyen <thu@os.amperecomputing.com>
+
+Description
+-----------
+
+This driver support the monitoring and configuration of various miscellaneous
+data provided by Ampere(R) Altra(R) SMpro processor.
+At this time, these include:
+
+ * Reading Boot Progress information
+ * Configuring SoC Power Limit
+
+Sysfs entries
+-------------
+
+1) Boot progress
+
+SMpro misc driver creates the sysfs files ``boot_progress``.
+The format of ``boot_progress`` file is as below::
+
+<boot stage><boot status><boot progress>
+
+Where:
+
+* Boot stage::
+
+ 0: SMpro firmware booting.
+ 1: PMpro firmware booting.
+ 2: ATF BL1 firmware booting.
+ 3: DDR initialization.
+ 4: DDR training report status.
+ 5: ATF BL2 firmware booting.
+ 6: ATF BL31 firmware booting.
+ 7: ATF BL32 firmware booting.
+ 8: UEFI firmware booting.
+ 9: OS booting.
+
+* Boot status::
+
+ 0: Not started.
+ 1: Started.
+ 2: Complete without error.
+ 3: Failure.
+
+* boot progress: 32 bits boot progress code
+
+The sysfs ``boot_progress`` only reports the boot state when the host is booting.
+If the host is already booted, it returns latest state.
+
+Example::
+
+ #cat boot_progress
+ 0102808454A8
+
+2) SoC Power Limit
+
+SMpro misc driver creates the sysfs file ``soc_power_limit`` to get/set the SoC Power Limit.
+
+Reading this sysfs return the current setting of SoC Power Limit (W) in decimal string.
+Writing the desired value in decimal string to set the SoC Power Limit in Watt (W).
+The range of SoC Power Limit is 90-500(W) and will be ignored if out of range.
+
+Example::
+
+ #cat soc_power_limit
+ 90
+ #echo 95 > soc_power_limit
+ #cat soc_power_limit
+ 95

Again, please put the Documentation/ABI/ entries in this commit so that
we can verify they are all correct. Putting them at the end of the
series makes it pretty impossible to review. Would you want to have to
match them all up the way you sent them?

Why is this file needed at all if you have the correct

instead of living in a file that will never be noticed if anything ever

Usage Notes
-----------
SMpro errmon driver creates the sysfs files for each error type.
-Example: ``error_core_ce`` to get Core CE error type.
+See :ref:`smpro_sysfs` for the list of errors and the corresponding
+sysfs files.
-* If the error is absented, the sysfs file returns empty.
-* If the errors are presented, one each read to the sysfs, the oldest error will be returned and clear, the next read will be returned with the next error until all the errors are read out.
+* If there is no errors, the sysfs file is empty.
+* Otherwise, when errors occur, the oldest error
+ will be returned on sysfs file reading and cleared. The next read will
+ return the next error until all the errors are read out.
-For each host error type, SMpro keeps a latest max number of errors. All the oldest errors that were not read out will be dropped. In that case, the read to the corresponding overflow sysfs will return 1, otherwise, return 0.
-Example: ``overflow_core_ce`` to report the overflow status of Core CE error type.
+For each host error type, SMpro keeps a latest max number of errors. All the
+oldest errors that were not read will be dropped. In that case, the read
+to the corresponding sysfs will return 1, otherwise return 0.
-The format of the error is depended on the error type.

-At this time, these include:
+The smpro-misc driver supports monitoring and configuration of various
+miscellaneous data provided by Ampere(R) Altra(R) SMpro processor.
+Currently, the driver supports:
- * Reading Boot Progress information
- * Configuring SoC Power Limit
+ * reading boot progress information
+ * configuring SoC power limit
Sysfs entries
-------------
1) Boot progress
-SMpro misc driver creates the sysfs files ``boot_progress``.
-The format of ``boot_progress`` file is as below::
+ The driver creates ``boot_progress`` sysfs file. Its format is described
+ as::
-<boot stage><boot status><boot progress>
+ <boot stage><boot status><boot progress>
-Where:
+ where:
-* Boot stage::
+ * ``<boot stage>`` can be:
- 0: SMpro firmware booting.
- 1: PMpro firmware booting.
- 2: ATF BL1 firmware booting.
- 3: DDR initialization.
- 4: DDR training report status.
- 5: ATF BL2 firmware booting.
- 6: ATF BL31 firmware booting.
- 7: ATF BL32 firmware booting.
- 8: UEFI firmware booting.
- 9: OS booting.

+ * 1: PMpro firmware booting.
+ * 2: ATF BL1 firmware booting.
+ * 3: DDR initialization.
+ * 4: DDR training report status.
+ * 5: ATF BL2 firmware booting.
+ * 6: ATF BL31 firmware booting.
+ * 7: ATF BL32 firmware booting.
+ * 8: UEFI firmware booting.
+ * 9: OS booting.
-* Boot status::
+ * ``<boot status>`` can be:
- 0: Not started.
- 1: Started.
- 2: Complete without error.
- 3: Failure.
+ * 0: Not started.
+ * 1: Started.
+ * 2: Complete without error.
+ * 3: Failure.
-* boot progress: 32 bits boot progress code
+ * ``<boot progress>``: 32-bit boot progress code
-The sysfs ``boot_progress`` only reports the boot state when the host is booting.
-If the host is already booted, it returns latest state.
+ The sysfs file only reports the boot state when the host is booting. If
+ the host is already booted, it returns the latest state.
-Example::

-2) SoC Power Limit
+2) SoC power limit
-SMpro misc driver creates the sysfs file ``soc_power_limit`` to get/set the SoC Power Limit.
+ The driver creates ``soc_power_limit`` sysfs file to get/set the SoC
+ power limit.
-Reading this sysfs return the current setting of SoC Power Limit (W) in decimal string.
-Writing the desired value in decimal string to set the SoC Power Limit in Watt (W).
-The range of SoC Power Limit is 90-500(W) and will be ignored if out of range.
+ Reading the file returns the current limit. Write the desired value in
+ decimal to set the limit (in watts). The valid limit range is 90-500 W.
+ If the value is out of range, it will be ignored.
-Example::
+ Example::
- #cat soc_power_limit
- 90
- #echo 95 > soc_power_limit

It is documented under the entry for the

I'm not sure what you mean by "to be generated automatically" but
information can be documented in the driver code itself and in the
Documentation/ABI entries.
Will drop this file and move them to both the driver code and to the
Documentaion/ABI entries in next version.

Thanks Guenter for picking the patches.
There are two issues found by Bagas [1] in document format and kernel
test robot [2] on smpro-hwmon.c. I'll fix them in separate patches.
