| 42 | ## Pcd8259LegacyModeMask defines the default mask value for platform. This value is determined
|
|---|
| 43 | # 1) If platform only support pure UEFI, value should be set to 0xFFFF or 0xFFFE;
|
|---|
| 44 | # Because only clock interrupt is allowed in legacy mode in pure UEFI platform.
|
|---|
| 45 | # 2) If platform install CSM and use thunk module:
|
|---|
| 46 | # a) If thunk call provided by CSM binary requires some legacy interrupt support, the corresponding bit
|
|---|
| 47 | # should be opened as 0.
|
|---|
| 48 | # For example, if keyboard interfaces provided CSM binary use legacy keyboard interrupt in 8259 bit 2, then
|
|---|
| 49 | # the value should be set to 0xFFFC
|
|---|
| 50 | # b) If all thunk call provied by CSM binary do not require legacy interrupt support, value should be set
|
|---|
| 51 | # to 0xFFFF or 0xFFFE.
|
|---|
| 52 | #
|
|---|
| 53 | # The default value of legacy mode mask could be changed by EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely
|
|---|
| 54 | # need change it except some special cases such as when initializing the CSM binary, it should be set to 0xFFFF to
|
|---|
| 55 | # mask all legacy interrupt. Please restore the original legacy mask value if changing is made for these special case.
