gned-off-by: Oded Gabbay <ogabbay@kernel.org> 2021-04-09habanalabs: support DEVICE_UNUSABLE error indication from FWKoby Elbaz In case of multiple ECC errors, FW will set the DEVICE_UNUSABLE bit. On boot-up, the driver will therefore fail inserting the device.

Formerly asic specific PLL numbering is now common for all asics. To be backward compatible a bit in dev status is defined, if the bit is not set LKD will keep working with old PLL numbering.

Signed-off-by: Oded Gabbay <ogabbay@kernel.org> 2020-12-28habanalabs/gaudi: disable CGM at HW initializationOded Gabbay In case the clock gating was enabled in preboot we need to disable it at the H/W initialization stage before touching the MME/TPC registers. Otherwise, the ASIC can get stuck. If the security is enabled in the firmware level, the CGM is always disabled and the driver can't enable it.

Driver will check if HW is dirty only after it validated preboot is up. If HW is dirty, driver will perform a hard reset according to the FW capability. In addition, FW defines a new message which driver need to send in order to initiate a hard reset.

This field was not used by the current ASICs so this change doesn't break anything. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> 2020-09-22habanalabs: Fix alignment issue in cpucp_info structureOfir Bitton Because the device CPU compiler aligns structures to 8 bytes, struct cpucp_info has an alignment issue as some parts in the structure are not aligned to 8 bytes. It is preferred that we explicitly insert placeholders inside the structure to avoid confusion in order to validate this scenario, we printed both pointers: __u8 cpucp_version[VERSION_MAX_LEN]; (0xffff899c67ed4cbc) __le64 dram_size; (0xffff899c67ed4d40) we see difference of 132 bytes although the first array is only 128 bytes long, Meaning compiler added a 4 byte padding.

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.
