habanalabs: expose reset counters via existing INFO IOCTL

2019-11-21T09:35:47+00:00

Expose both soft and hard reset counts via INFO IOCTL.
This will allow system management applications to easily check
if the device has undergone reset.

habanalabs: export uapi defines to user-space

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

The two defines that control the maximum size of a command buffer and the
maximum number of JOBS per CS need to be exported to the user as they are
part of the API towards user-space.

habanalabs: expose card name in INFO IOCTL

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

To enable userspace processes, e.g. management utilities, to display the
card name to the user, add the card name property to the HW_IP
structure that is copied to the user in the INFO IOCTL.

habanalabs: add opcode to INFO IOCTL to return clock rate

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

Add a new opcode to the INFO IOCTL to allow the user application to
retrieve the ASIC's current and maximum clock rate. The rate is
returned in MHz.

misc: fastrpc: add mmap/unmap support

2019-10-10T13:28:10+00:00

Support the allocation/deallocation of buffers mapped to the DSP.

When the memory mapped to the DSP at process creation is not enough,
the fastrpc library can extend it at runtime. This avoids having to do
large preallocations by default.

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.

habanalabs: add uapi to retrieve aggregate H/W events

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

Add a new opcode to INFO IOCTL to retrieve aggregate H/W events. i.e. the
events counters are NOT cleared upon device reset, but count from the
loading of the driver.

Add the code to support it in the device event handling function.

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.

habanalabs: Make the Coresight timestamp perpetual

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

The Coresight timestamp is enabled for a specific debug session using
the HL_DEBUG_OP_TIMESTAMP opcode of the debug IOCTL.
In order to have a perpetual timestamp that would be comparable between
various debug sessions, this patch moves the timestamp enablement to be
part of the HW initialization.
The HL_DEBUG_OP_TIMESTAMP opcode turns to be deprecated and shouldn't be
used. Old user-space that will call it won't see any change in the
behavior of the debug session.
