habanalabs: split MMU properties to PCI/DRAM

2019-11-21T09:35:46+00:00

Split the properties used for MMU mappings to DRAM and PCI (host) types. This is a prerequisite for future ASICs support. Note that in Goya ASIC, the PMMU and DMMU are the same (except of page sizes) as only one MMU mechanism is used for both of the mapping types. Hence this patch should not have any effect on current behavior. Signed-off-by: Omer Shpigelman Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: re-factor MMU masks and documentation

2019-11-21T09:35:46+00:00

Some cosmetics around the MMU code to make it more self-explanatory. Signed-off-by: Omer Shpigelman Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: set ETR as non-secured

2019-11-21T09:35:45+00:00

ETR should always be non-secured as it is used by the users to record profiling/trace data. Signed-off-by: Oded Gabbay Reviewed-by: Omer Shpigelman

habanalabs: use registers name defines for ETR block

2019-11-21T09:35:45+00:00

We have a single ETR block in the SOC, so use explicit register name defines for initializing this block. This makes it more readable and maintainable. Signed-off-by: Oded Gabbay Reviewed-by: Omer Shpigelman

habanalabs: Add a new H/W queue type

2019-11-21T09:35:45+00:00

This patch adds a support for a new H/W queue type. This type of queue is for DMA and compute engines jobs, for which completion notification are sent by H/W. Command buffer for this queue can be created either through the CB IOCTL and using the retrieved CB handle, or by preparing a buffer on the host or device SRAM/DRAM, and using the device address to that buffer. The patch includes the handling of the 2 options, as well as the initialization of the H/W queue and its jobs scheduling.

habanalabs: handle F/W failure for sensor initialization

2019-11-21T09:35:44+00:00

In case the F/W fails to initialize the thermal sensors, print an appropriate error message to kernel log and fail the device initialization. Reviewed-by: Tomer Tayar Signed-off-by: Oded Gabbay

habanalabs: stop using the acronym KMD

2019-09-05T11:55:27+00:00

We want to stop using the acronym KMD. Therefore, replace all locations (except for register names we can't modify) where KMD is written to other terms such as "Linux kernel driver" or "Host kernel driver", etc. Signed-off-by: Oded Gabbay Reviewed-by: Omer Shpigelman

habanalabs: display card name as sensors header

2019-09-05T11:55:27+00:00

To allow the user to use a custom file for the HWMON lm-sensors library per card type, the driver needs to register the HWMON sensors with the specific card type name. The card name is supplied by the F/W running on the device. If the F/W is old and doesn't supply a card name, a default card name is displayed as the sensors group name.

habanalabs: add uapi to retrieve device utilization

2019-09-05T11:55:27+00:00

Users and sysadmins usually want to know what is the device utilization as a level 0 indication if they are efficiently using the device. Add a new opcode to the INFO IOCTL that will return the device utilization over the last period of 100-1000ms. The return value is 0-100, representing as percentage the total utilization rate.
