[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [RFC PATCH v3 7/7] xen/arm: scmi: generate scmi dt node for DomUs
From: Oleksii Moisieiev <oleksii_moisieiev@xxxxxxxx>
This feature introduces SCMI support for DomU domains with partial SCMI DT
node generation.
During domain creation the following prerequisites are expected:
- SCMI node template in partial device-tree, which should contain all
subnodes used by DomU:
/ {
firmware {
scmi {
scmi_reset: protocol@19 {
\#reset-cells = <1>;
};
scmi_clk: protocol@14 {
\#clock-cells = <1>;
};
scmi_pinctrl: protocol@19 {
sdio_mux: mux {
};
mux1: mux1 {
};
};
};
};
passthrough {
sdio {
pinctrl-0 = <&sdio_mux>;
resets = <&scmi_reset 0x1>;
clocks = <&scmi_clk 0x1>;
};
dev1 {
resets = <&scmi_reset 2>;
pinctrl-0 = <&mux1>;
};
};
};
- properly defined "arm_sci" property in domain xl.cfg:
arm_sci = "type=scmi_smc_multiagent,agent_id=2"
- Platform/Xen DT exposed to Dom0 through Xen hypfs.
The Xen toolstack:
- obtains from Xen information about phys address of the SCMI shmem and
SMC/HVC id used by specified SCMI agent_id (domctl
XEN_DOMCTL_get_sci_info)
- creates the SCMI shmem node in domain DT using predefined guest MMIO
mappings and DT phandle
GUEST_SCI_SHMEM_BASE xen_mk_ullong(0x22001000)
GUEST_SCI_SHMEM_SIZE xen_mk_ullong(0x01000)
GUEST_PHANDLE_SCMI (GUEST_PHANDLE_IOMMU + 1)
- creates SCMI node in domain DT with:
- "shmem" phandle sets to GUEST_PHANDLE_SCMI
- "arm,smc-id" sets to SMC/HVC id obtained from Xen
- parses partial device tree and creates corresponding SCMI subnodes in
domain DT. All SCMI subnodes properties are copied from Xen DT except
phandles, which are taken from partial DT.
- maps the SCMI shmem into DomU GUEST_SCI_SHMEM_BASE address.
