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 reStructuredText 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.

Due to the current design of the BO and VRAM manager, any object with XE_BO_FLAG_PINNED flag, which the PF driver uses during VF LMEM provisionining, is created with the TTM_PL_FLAG_CONTIGUOUS flag, which may cause VRAM fragmentation that prevents subsequent allocations of larger objects, like fair VF LMEM provisioning. To avoid such failures, round down fair VF LMEM provisioning size to next power of two size, to compensate what xe_ttm_vram_mgr is doing to achieve contiguous allocations.
