[PATCH V5 0/8] Add basic ACPI support for risc-v virt
Posted by Sunil V L 1 year, 1 month ago
This series adds the basic ACPI support for the RISC-V virt machine. 
Currently only RINTC interrupt controller specification is approved by the
UEFI forum. External interrupt controller support in ACPI is in progress.

This adds support for RINTC and RHCT tables as specified in below ECR links
which are approved by UEFI forum.
RINTC - https://drive.google.com/file/d/1R6k4MshhN3WTT-hwqAquu5nX6xSEqK2l/view
RHCT - https://drive.google.com/file/d/1nP3nFiH4jkPMp6COOxP6123DCZKR-tia/view

These changes are also available @
https://github.com/vlsunil/qemu/tree/acpi_b1_us_review_V5

Changes since V4:
	1) Used possible_cpus to create cpu topology in DSDT, MADT and RHCT as
           per Igor's feedback.
        2) Moved MAINTAINER entries below ACPI/SMBIOS entry as per Drew's
           feedback
Changes since V3:
	1) Added back acpi_align_size() wrapper as per Drew's feedback
	2) Updated RB tags

Changes since V2:
	1) Squashed commits and updated commit message as per feedback from Daniel.
	2) Addressed comments from Drew.
	3) Updated tags.

Changes since V1:
	1) Addressed comments from Bin Meng.
	2) Made acpi switch default AUTO similar to other architectures.
	3) Re-based and added RB and ACKs.

The series is tested using SBI HVC console and initrd.

Test instructions:
1) Build Qemu with ACPI support (this series)

2) Build EDK2 as per instructions in
https://github.com/vlsunil/riscv-uefi-edk2-docs/wiki/RISC-V-Qemu-Virt-support

3) Build Linux with ACPI support using below branch
https://github.com/vlsunil/linux/commits/acpi_b1_us_review_ipi17_V2
after enabling SBI HVC and SBI earlycon options.

CONFIG_RISCV_SBI_V01=y
CONFIG_SERIAL_EARLYCON_RISCV_SBI=y
CONFIG_HVC_RISCV_SBI=y

4) Build buildroot.

Run with below command.
qemu-system-riscv64   -nographic \
-drive file=Build/RiscVVirtQemu/RELEASE_GCC5/FV/RISCV_VIRT.fd,if=pflash,format=raw,unit=1 \
-machine virt -smp 16 -m 2G \
-kernel arch/riscv/boot/Image \
-initrd buildroot/output/images/rootfs.cpio \
-append "root=/dev/ram ro console=hvc0 earlycon=sbi"

Thanks.  These all look good to me, but given that Igor had some 
feedback on the v4 and it's pretty much just been weekend since t hese 
went out I'm going to hold off until tomorrow before merging anything.  
They're all staged and passing the tests on my end, so everything's good 
as far as I'm concerned.

I've queued these up on riscv-to-apply.next.  I know it's pretty last 
minute, but IMO we're better off having these a cycle earlier as a lot 
of the dependencies here are cross-project and it'll be better tested if 
released.

If anyone has an issue please say something, I'll be tagging a PR soon.
