Review request for ACPI ECRs

Hi All,
Please review below Engineering Change Request (ECR) to update the ACPI spec for enabling basic ACPI support for RISC-V. 1) Add INTC structure in MADT Table - https://docs.google.com/document/d/13YdZzUv0mRHBotdy4Qjqrzb-83mjM31AyEXXfgodcNw/edit?usp=sharing 2) Add new RISC-V Hart Capabilities Table (RHCT). https://docs.google.com/document/d/1-hQMzSNTEfNqudIENhGxrrb0Yr5MEo4NcZwXZlvdx6k/edit?usp=sharing 3) Add AIA interrupt controllers in MADT table https://docs.google.com/document/d/1rbdXsON4OMJ0QB3UvkfkIa8hdySbWArIKqPRUli7AU0/edit?usp=sharing First two ECRs do not have a dependency on any RVI specs which are not frozen. But the third ECR has a dependency on AIA spec to be frozen. Hence this AIA ECR will NOT be sent to UEFI forum until AIA spec is frozen. The PoC for these ECRs is complete and ACPI enabled Linux boots on qemu platform. Below are links to the source code for the PoC. qemu - https://github.com/ventanamicro/qemu/tree/dev-upstream edk2 - https://github.com/ventanamicro/edk2/tree/dev-upstream edk2-platforms - https://github.com/ventanamicro/edk2-platforms/tree/dev-upstream linux - https://github.com/ventanamicro/linux/tree/dev-upstream You can find how to build and test these changes in this link - https://github.com/riscv-non-isa/riscv-acpi/wiki/PoC-:-How-to-build-and-test-ACPI-enabled-kernel You can provide the feedback by commenting in the document itself. I am hoping to send at least first two ECRs to UEFI forum by 8th August 2022. So, appreciate your help to improve these ECRs before 4th August 2022 (45 days from today). Feel free to reach out if you have any questions. Thanks! Sunil |

Please provide your comments in this version of the documents. 1) Non-AIA ECRs a) RHCT - version 2: https://docs.google.com/document/d/1LlCefO_0GQ_7Tf3lzfMPETEfMlGo2FfLRJ09IMqJKEk/edit?usp=sharing b)MADT RINTC - version 2: https://docs.google.com/document/d/1waaAqDyTWvYcCSd1Df-vj0EKCA1nukKF_puclaVYkSo/edit?usp=sharing 2) AIA ECRs a) MADT - AIA RINTC (version 2) : https://docs.google.com/document/d/1LBKD1gyi6kOfE3V2WiFOPz1h4MlmxHDj7vkjjfSygBo/edit?usp=sharing b) MADT - AIA IMSIC/APLIC version 2: https://docs.google.com/document/d/1zDainvcxD14eawsyc3y1s78zP7ruefyGzcsP1bBak3w/edit?usp=sharing PoC Code has been updated at same location as earlier.
