Subject: [PATCH v2 00/17] RPMI and SBI MPXY support for OpenSBI
Date: Fri, 29 Nov 2024 21:20:35 +0530 [thread overview]
Message-ID: <20241129155052.2866712-1-apatel@ventanamicro.com> (raw)
This series adds RPMI and SBI MPXY support for OpenSBI. The RPMI service
groups supported include system reset, system suspend, HSM, CPPC, and
clock. The RPMI clock serivice group is exposed to supervisor software
as an MPXY channel.
These patches can also be found in the rpmi_mpxy_v2 branch at:
https://github.com/avpatel/opensbi.git
To test these patches, use the dev-upstream branch of the following repos:
* https://github.com/ventanamicro/qemu.git
* https://github.com/ventanamicro/linux.git
To enable QEMU RPMI emulation (using librpmi) for virt machine, use
"virt,rpmi=on" as the QEMU machine name.
Changes since v1:
- Rebased on latest OpenSBI
- Use the recently introduced helpers for generic driver initialization
- Updated RPMI drivers to match the latest RPMI specification
- Don't support fixed number of channels in RPMI shared memory mailbox driver
- Added new patch9 for support RPMI HSM based FDT fixup
- Improved arrangment of barrier in __smq_rx() and __smq_tx()
