Message-ID: <20190704065843.GA21559@ogabbay-VM> (raw)
Hello Greg,
This is v2 of the pull request for habanalabs driver for kernel 5.3.
v2 contains the missing sign-off-by tags for the relevant commits.
The commits mostly contains improvements to the existing code base.
Nothing too exciting this time.
Please see the tag message for details on what this pull request contains.
Thanks,

habanalabs: Add busy engines bitmask to HW idle IOCTL (2019-07-01 13:59:45 +0000)
----------------------------------------------------------------
This tag contains the following changes for kernel 5.3:
- Change the way the device's CPU access the host memory. This allows the
driver to use the kernel API of setting DMA mask in a standard way (call
it once).
- Add a new debugfs entry to show the status of the internal DMA and
compute engines. This is very helpful for debugging in case a command
submission get stuck.
- Return to the user a mask of the internal engines indicating their busy
state.
- Make sure to restore registers that can be modified by the user to their
default values. Only applies to registers that are initialized by the
driver.
- Elimination of redundant and dead-code.
- Support memset of the device's memory with size larger then 4GB
- Force the user to set the device to debug mode before configuring the
device's coresight infrastructure
- Improve error printing in case of interrupts from the device
