Jiri Pirko says: ==================== devlink: Add support for resource abstraction Arkadi says: Many of the ASIC's internal resources are limited and are shared between several hardware procedures. For example, unified hash-based memory can be used for many lookup purposes, like FDB and LPM. In many cases the user can provide a partitioning scheme for such a resource in order to perform fine tuning for his application. In such cases performing driver reload is needed for the changes to take place, thus this patchset also adds support for hot reload. Such an abstraction can be coupled with devlink's dpipe interface, which models the ASIC's pipeline as a graph of match/action tables. By modeling the hardware resource object, and by coupling it to several dpipe tables, further visibility can be achieved in order to debug ASIC-wide issues. The proposed interface will provide the user the ability to understand the limitations of the hardware, and receive notification regarding its occupancy. Furthermore, monitoring the resource occupancy can be done in real-time and can be useful in many cases. --- v2->v3 - Mix/Max/Gran attributes. - Add resource consumption per table. - Change basic resource unit to 'entry'. - ABI documentation. v1->v2 - Add resource size attribute. - Fix split bug. ==================== Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
