Oded writes: 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 * tag 'misc-habanalabs-next-2019-07-04' of git://people.freedesktop.org/~gabbayo/linux: (31 commits) habanalabs: Add busy engines bitmask to HW idle IOCTL habanalabs: Add debugfs node for engines status habanalabs: Update the device idle check habanalabs: Allow accessing host mapped addresses via debugfs habanalabs: add WARN in case of bad MMU mapping habanalabs: remove DMA mask hack for Goya habanalabs: set Goya CPU to use ASIC MMU habanalabs: add MMU mappings for Goya CPU habanalabs: initialize MMU context for driver habanalabs: de-couple MMU and VM module initialization habanalabs: initialize device CPU queues after MMU init docs/habanalabs: update text for some entries in sysfs habanalabs: add rate-limit to an error message habanalabs: remove simulator dedicated code habanalabs: restore unsecured registers default values habanalabs: clear sobs and monitors in context switch habanalabs: make tpc registers secured habanalabs: don't limit packet size for device CPU habanalabs: support device memory memset > 4GB habanalabs: print event name for fatal and non-RAZWI events ...
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
