Now that each FW has its own reserved area, we can keep them always pinned and skip the pin/unpin dance on reset. This will make things easier for the 2-step HuC authentication, which requires the FW to be pinned in GGTT after the xfer is completed. Since the vma is now valid for a long time and not just for the quick pin-load-unpin dance, the name "dummy" is no longer appropriare and has been replaced with vma_res. All the functions have also been updated to operate on vma_res for consistency. Given that we pin the vma behind the allocator's back (which is ok because we do the pinning in an area that was previously reserved for thus purpose), we do need to explicitly re-pin on resume because the automated helper won't cover us. v2: better comments and commit message, s/dummy/vma_res/ Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Alan Previn <alan.previn.teres.alexis@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230531235415.1467475-2-daniele.ceraolospurio@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.
