Itanium support has been removed from EDK2 aroun 2019.
|
|
|
8ff9b3 |
ITANIUM_HANDOFF_STATUS data structure looks to be
|
|
|
8ff9b3 |
some leftover from that process.
|
|
|
8ff9b3 |
|
|
|
8ff9b3 |
There is also positive sidefect of this data structure removal.
|
|
|
8ff9b3 |
Due to HOB allocation type used in PEI stage there is a limit
|
|
|
8ff9b3 |
how much data about virtual CPU can be hold. This limit result
|
|
|
8ff9b3 |
in only 1024 vCPU can be used by VM.
|
|
|
8ff9b3 |
With Itanium related data structure removed more allocated space
|
|
|
8ff9b3 |
can be used for vCPU data and with current allocation limit
|
|
|
8ff9b3 |
will change from 1024 to around 8k vCPUs.
