b6f2f446f66ff9 Cedric Xing 2025-04-07 54 * methods for updating measurement registers (MRs).
b6f2f446f66ff9 Cedric Xing 2025-04-07 55 * @name: Optional parent directory name.

b6f2f446f66ff9 Cedric Xing 2025-04-07 57 * @nr_mrs: Number of elements in @mrs.
b6f2f446f66ff9 Cedric Xing 2025-04-07 58 * @refresh: Callback function to load/sync all MRs from TVM hardware/firmware
b6f2f446f66ff9 Cedric Xing 2025-04-07 59 * into the kernel cache.
b6f2f446f66ff9 Cedric Xing 2025-04-07 60 * @write: Callback function to write to the MR specified by the parameter @mr.

b6f2f446f66ff9 Cedric Xing 2025-04-07 62 * @refresh takes two parameters:

b6f2f446f66ff9 Cedric Xing 2025-04-07 64 * * @tm - points back to this structure.
b6f2f446f66ff9 Cedric Xing 2025-04-07 65 * * @mr - points to the MR (an element of @mrs) being read (hence triggered
b6f2f446f66ff9 Cedric Xing 2025-04-07 66 * this callback).

b6f2f446f66ff9 Cedric Xing 2025-04-07 70 * the MR being read (@mr) but also all MRs with %TSM_MR_F_LIVE set.

b6f2f446f66ff9 Cedric Xing 2025-04-07 72 * @write takes an additional parameter besides @tm and @mr:
b6f2f446f66ff9 Cedric Xing 2025-04-07 73 *
b6f2f446f66ff9 Cedric Xing 2025-04-07 74 * * @data - contains the bytes to write and whose size is @mr->mr_size.

b6f2f446f66ff9 Cedric Xing 2025-04-07 76 * Both @refresh and @write should return 0 on success and an appropriate error
