2020-11-30T08:47:36+00:00

through the firmware message interface instead of reading the registers
directly.

habanalabs: add 'needs reset' state in driver

2020-11-30T08:47:33+00:00

The new state indicates that device should be reset in order
to re-gain funcionality.
This unique state can occur if reset_on_lockup is disabled
and an actual lockup has occurred.

habanalabs: fix cs counters structure

2020-11-30T08:47:31+00:00

Fix cs counters structure in uapi to be one flat structure instead
of two instances of the same other structure.
use atomic read/increment for context counters so we could use
one structure for both aggregated and context counters.

habanalabs: use enum for CB allocation options

2020-11-30T08:47:29+00:00

In the future there will be situations where queues can accept either
kernel allocated CBs or user allocated CBs, depending on different
states.

Therefore, instead of using a boolean variable of kernel/user allocated
CB, we need to use a bitmask to indicate that, which will allow to
combine the two options.

Add a flag to the uapi so the user will be able to indicate whether
the CB was allocated by kernel or by user. Of course the driver
validates that.
