Subject: [PATCH 0/4] Driver updates to match frozen RPMI specification
Date: Mon, 12 May 2025 14:08:23 +0530 [thread overview]
Message-ID: <20250512083827.804151-1-apatel@ventanamicro.com> (raw)
The RPMI v1.0 specification is frozen and in public review so update
RPMI drivers to match last minute specification changes which were
based on ARC feedback.
These patches can also be found in the rpmi_fixes_v1 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,aia=aplic-imsic" as the QEMU machine name.
