Rather than open coding VM binds and VMA tracking, use the GPUVA library. GPUVA provides a common infrastructure for VM binds to use mmap / munmap semantics and support for VK sparse bindings. The concepts are: 1) xe_vm inherits from drm_gpuva_manager 2) xe_vma inherits from drm_gpuva 3) xe_vma_op inherits from drm_gpuva_op 4) VM bind operations (MAP, UNMAP, PREFETCH, UNMAP_ALL) call into the GPUVA code to generate an VMA operations list which is parsed, committed, and executed. v2 (CI): Add break after default in case statement. v3: Rebase v4: Fix some error handling v5: Use unlocked version VMA in error paths v6: Rebase, address some review feedback mainly Thomas H v7: Fix compile error in xe_vma_op_unwind, address checkpatch Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
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.
