 260   ## Pcd8259LegacyModeMask defines the default mask value for platform. This
 261   #  value is determined.
 262   #  1) If platform only support pure UEFI, value should be set to 0xFFFF or
 263   #     0xFFFE; Because only clock interrupt is allowed in legacy mode in pure
 264   #     UEFI platform.
 265   #  2) If platform install CSM and use thunk module:
 266   #     a) If thunk call provided by CSM binary requires some legacy interrupt
 267   #        support, the corresponding bit should be opened as 0.
 268   #        For example, if keyboard interfaces provided CSM binary use legacy
 269   #        keyboard interrupt in 8259 bit 1, then the value should be set to
 270   #        0xFFFC.
 271   #     b) If all thunk call provied by CSM binary do not require legacy
 272   #        interrupt support, value should be set to 0xFFFF or 0xFFFE.
 273   #
 274   #  The default value of legacy mode mask could be changed by
 275   #  EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely need change it
 276   #  except some special cases such as when initializing the CSM binary, it
 277   #  should be set to 0xFFFF to mask all legacy interrupt. Please restore the
