Our current FW loading process is the same for all FWs: - Pin FW to GGTT at the start of the ggtt->uc_fw node - Load the FW - Unpin This worked because we didn't have a case where 2 FWs would be loaded on the same GGTT at the same time. On MTL, however, this can happen if both GTs are reset at the same time, so we can't pin everything in the same spot and we need to use separate offset. For simplicity, instead of calculating the exact required size, we reserve a 2MB slot for each fw. v2: fail fetch if FW is > 2MBs, improve comments (John) v3: more comment improvements (John) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: John Harrison <john.c.harrison@intel.com> Cc: Alan Previn <alan.previn.teres.alexis@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221108020600.3575467-3-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.
