The PMF driver allocates a shared memory buffer using tee_shm_alloc_kernel_buf() for communication with the PMF-TA. The latest PMF-TA version introduces new structures with OEM debug information and additional policy input conditions for evaluating the policy binary. Consequently, the shared memory size must be increased to ensure compatibility between the PMF driver and the updated PMF-TA. To do so, introduce the new PMF-TA UUID and update the PMF shared memory configuration to ensure compatibility with the latest PMF-TA version. Additionally, export the TA UUID. These updates will result in modifications to the prototypes of amd_pmf_tee_init() and amd_pmf_ta_open_session().

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.
