| 26 | ## Pcd8259LegacyModeMask defines the default mask value for platform. This value is determined\r |
| 27 | # 1) If platform only support pure UEFI, value should be set to 0xFFFF or 0xFFFE;\r |
| 28 | # Because only clock interrupt is allowed in legacy mode in pure UEFI platform.\r |
| 29 | # 2) If platform install CSM and use thunk module:\r |
| 30 | # a) If thunk call provided by CSM binary requires some legacy interrupt support, the corresponding bit \r |
| 31 | # should be opened as 0.\r |
| 32 | # For example, if keyboard interfaces provided CSM binary use legacy keyboard interrupt in 8259 bit 2, then\r |
| 33 | # the value should be set to 0xFFFC\r |
| 34 | # b) If all thunk call provied by CSM binary do not require legacy interrupt support, value should be set\r |
| 35 | # to 0xFFFF or 0xFFFE.\r |
| 36 | #\r |
| 37 | # Because the value is used as intialization value, PCD's type should be FixedAtBuild.\r |
| 38 | #\r |
| 39 | # The default value of legacy mode mask could be changed by EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely\r |
| 40 | # need change it except some special cases such as when initializing the CSM binary, it should be set to 0xFFFF to \r |
| 41 | # mask all legacy interrupt. Please restore the original legacy mask value if changing is made for these special case.\r |
