2021-01-27habanalabs: update email address in sysfs/debugfs docsOded Gabbay1-29/+29
Use my kernel.org address for contact point instead of my private email address. Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
2020-09-22habanalabs: replace armcp with the generic cpucpOded Gabbay1-1/+17
ArmCP mandates that the device CPU is always an ARM processor, which might be wrong in the future. Most of this change is an internal renaming of variables, functions and defines but there are two entries in sysfs which have armcp in their names. Add identical cpucp entries but don't remove yet the armcp entries. Those will be deprecated next year. Add the documentation about it in sysfs documentation.

2020-05-19habanalabs: add hwmgr module for gaudiOded Gabbay1-0/+17
The hwmgr module is responsible for messages sent to GAUDI F/W that are not common to all habanalabs ASICs. In GAUDI, we provide the user a simplified mode of controlling the ASIC clock frequency. Instead of three different clocks, we present a single clock property that the user can configure via sysfs. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-09-05habanalabs: power management through sysfs is only for GOYAOded Gabbay1-2/+3
The ability of setting power management properties by the system administrator (through sysfs properties) is only relevant for the GOYA ASIC. Therefore, move the relevant sysfs properties to the GOYA sysfs specific file, to make the properties appear in sysfs only for GOYA cards.

2019-09-05habanalabs: remove write_open_cnt propertyOded Gabbay1-8/+1
This property has attempted to show the number of open file descriptors on the device. This was a stupid and futile attempt so remove this property completely. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-06-06docs/habanalabs: update text for some entries in sysfsOded Gabbay1-18/+24
This patch updates the description of some entries in sysfs for the habanalabs driver. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-02-18habanalabs: add sysfs and hwmon supportOded Gabbay1-0/+190
This patch add the sysfs and hwmon entries that are exposed by the driver. Goya has several sensors, from various categories such as temperature, voltage, current, etc. The driver exposes those sensors in the standard hwmon mechanism. In addition, the driver exposes a couple of interfaces in sysfs, both for configuration and for providing status of the device or driver. The configuration attributes is for Power Management: - Automatic or manual - Frequency value when moving to high frequency mode - Maximum power the device is allowed to consume The rest of the attributes are read-only and provide the following information: - Versions of the various firmwares running on the device - Contents of the device's EEPROM - The device type (currently only Goya is supported) - PCI address of the device (to allow user-space to connect between /dev/hlX to PCI address) - Status of the device (operational, malfunction, in_reset) - How many processes are open on the device's file Reviewed-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
