Subject: [RFC PATCH v2 00/17] Linux SBI MPXY and RPMI drivers
The SBI v3.0 MPXY extension [1] and RPMI v1.0 [2] specifications are
in stable state and under ARC review at the RISC-V International so
as part of the RVI process we would like to receive an early feedback
on the device tree bindings and mailbox drivers hence this series.
Currently, most of the RPMI and MPXY drivers are in OpenSBI whereas
for Linux only has SBI MPXY mailbox controller driver, RPMI clock
driver.and RPMI system MSI driver This series also includes ACPI
support for SBI MPXY mailbox controller and RPMI system MSI drivers.
These patches can be found in the riscv_sbi_mpxy_mailbox_v2 branch at:
https://github.com/avpatel/linux.git
To test these patches, boot Linux on "virt,rpmi=on,aia=aplic-imsic"
machine with OpenSBI and QEMU from the dev-upstream QEMU branch at:
https://github.com/ventanamicro/opensbi.git
https://github.com/ventanamicro/qemu.git
[1] https://github.com/riscv-non-isa/riscv-sbi-doc/releases
[2] https://github.com/riscv-non-isa/riscv-rpmi/releases
Changes since v1:
- Addressed DT bindings related comments in PATCH2, PATCH3, and
PATCH7 of v1 series
- Addressed comments in PATCH6 and PATCH8 of v1 series
- New PATCH6 in v2 series to allow fwnode based mailbox channel
request
- New PATCH10 and PATCH11 to add RPMI system MSI based interrupt
controller driver
- New PATCH12 to PATCH16 which adds ACPI support in SBI MPXY
mailbox driver and RPMI system MSI driver
- New PATCH17 to enable required kconfig option to allow graceful
shutdown on QEMU virt machine
