29 ## Pcd8259LegacyModeMask defines the default mask value for platform. This value is determined
30 # 1) If platform only support pure UEFI, value should be set to 0xFFFF or 0xFFFE;
31 # Because only clock interrupt is allowed in legacy mode in pure UEFI platform.
32 # 2) If platform install CSM and use thunk module:
33 # a) If thunk call provided by CSM binary requires some legacy interrupt support, the corresponding bit
34 # should be opened as 0.
35 # For example, if keyboard interfaces provided CSM binary use legacy keyboard interrupt in 8259 bit 2, then
36 # the value should be set to 0xFFFC
37 # b) If all thunk call provied by CSM binary do not require legacy interrupt support, value should be set
38 # to 0xFFFF or 0xFFFE.
39 #
40 # The default value of legacy mode mask could be changed by EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely
41 # need change it except some special cases such as when initializing the CSM binary, it should be set to 0xFFFF to
42 # mask all legacy interrupt. Please restore the original legacy mask value if changing is made for these special case.
