This value is determined # 1) If platform only support pure UEFI, value should be set to 0xFFFF or 0xFFFE; # Because only clock interrupt is allowed in legacy mode in pure UEFI platform. # 2) If platform install CSM and use thunk module: # a) If thunk call provided by CSM binary requires some legacy interrupt support, the corresponding bit # should be opened as 0. # For example, if keyboard interfaces provided CSM binary use legacy keyboard interrupt in 8259 bit 2, then # the value should be set to 0xFFFC # b) If all thunk call provied by CSM binary do not require legacy interrupt support, value should be set # to 0xFFFF or 0xFFFE. # # The default value of legacy mode mask could be changed by EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely # need change it except some special cases such as when initializing the CSM binary, it should be set to 0xFFFF to # mask all legacy interrupt. Please restore the original legacy mask value if changing is made for these special case. # gPcAtChipsetPkgTokenSpaceGuid.Pcd8259LegacyModeMask|0xFFFF|UINT16|0x00000001 ## Pcd8259LegacyModeEdgeLevel defines the default edge level for legacy mode's interrrupt controller. gPcAtChipsetPkgTokenSpaceGuid.Pcd8259LegacyModeEdgeLevel|0x0000|UINT16|0x00000002 ## This PCD specifies whether we need enable IsaAcpiCom1 device. gPcAtChipsetPkgTokenSpaceGuid.PcdIsaAcpiCom1Enable|TRUE|BOOLEAN|0x00000003 ## This PCD specifies whether we need enable IsaAcpiCom2 device. gPcAtChipsetPkgTokenSpaceGuid.PcdIsaAcpiCom2Enable|TRUE|BOOLEAN|0x00000004 ## This PCD specifies whether we need enable IsaAcpiPs2Keyboard device. gPcAtChipsetPkgTokenSpaceGuid.PcdIsaAcpiPs2KeyboardEnable|TRUE|BOOLEAN|0x00000005 ## This PCD specifies whether we need enable IsaAcpiPs2Mouse device. gPcAtChipsetPkgTokenSpaceGuid.PcdIsaAcpiPs2MouseEnable|TRUE|BOOLEAN|0x00000006 ## This PCD specifies whether we need enable IsaAcpiFloppyA device. gPcAtChipsetPkgTokenSpaceGuid.PcdIsaAcpiFloppyAEnable|TRUE|BOOLEAN|0x00000007 ## This PCD specifies whether we need enable IsaAcpiFloppyB device. gPcAtChipsetPkgTokenSpaceGuid.PcdIsaAcpiFloppyBEnable|TRUE|BOOLEAN|0x00000008 [Guids] gPcAtChipsetPkgTokenSpaceGuid = { 0x326ae723, 0xae32, 0x4589, { 0x98, 0xb8, 0xca, 0xc2, 0x3c, 0xdc, 0xc1, 0xb1 } }
