Enable EINJv2 Support
|
expand
|
The goal of this update is to allow the driver to simultaneously support EINJ and EINJv2. The implementation follows the approved ACPI specs(1)(2) that enables the driver to discover system capabilities through GET_ERROR_TYPE. Note: The first two ACPICA patches are to be dropped once merged in ACPICA project, see pull request(3). (1) https://github.com/tianocore/edk2/issues/9449 (2) https://github.com/tianocore/edk2/issues/9017 (3) https://github.com/acpica/acpica/pull/977 Note: This revision includes a minor change to the user interface, where users no longer input component array size, instead the size of the array is parsed by counting lines from user input.
