2020-09-22habanalabs: no need for DMA_SHARED_BUFFEROded Gabbay1-1/+0
Now that the driver no longer uses dma_buf, we can remove the select of DMA_SHARED_BUFFER from kconfig. Signed-off-by: Oded Gabbay <[email protected]>
2020-09-22habanalabs: allow to wait on CS without sleepOded Gabbay1-2/+5
The user sometimes wants to check if a CS has completed to clean resources. In that case, the user doesn't want to sleep but just to check if the CS has finished and continue with his code. Add a new definition to the API of the wait on CS. The new definition says that if the timeout is 0, the driver won't sleep at all but return immediately after checking if the CS has finished.

2020-09-22habanalabs/gaudi: increase timeout for boot fit loadOded Gabbay1-1/+1
The firmware running in the boot stage takes more time to execute due to increased security mechanisms. Therefore, we need to increase the timeout we wait for the boot fit to finish loading. Signed-off-by: Oded Gabbay <[email protected]>

2020-09-22habanalabs: use smallest possible alignment for virtual addressesOmer Shpigelman1-38/+48

For future ASICs, we increase this field by one nibble. This field was not used by the current ASICs so this change doesn't break anything. Signed-off-by: Oded Gabbay <[email protected]>
2020-09-22habanalabs: Fix alignment issue in cpucp_info structureOfir Bitton1-0/+1
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.

2020-09-22habanalabs: replace armcp with the generic cpucpOded Gabbay13-313/+331
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.
