lib: sbi: Add initial domain context management support

2024-03-10T04:56:42Z

The domain context management component in OpenSBI provides basic CPU context management routines for existing OpenSBI domain. As domain extension, it was initially designed to facilitate the suspension and resumption of domains, enabling secure domains to efficiently share CPU resources. The patch also provides an addition to the OpenSBI domain to provide updates on hart-domain assignment and declarations of contexts within the domain.

platform: generic: Add system suspend test

2023-02-27T14:20:51Z

When the system-suspend-test property is present in the domain config node as shown below, implement system suspend with a simple 5 second delay followed by a WFI. This allows testing system suspend when the low-level firmware doesn't support it. / { chosen { opensbi-domains { compatible = "opensbi,domain,config"; system-suspend-test; }; Signed-off-by: Andrew Jones Reviewed-by: Anup Patel

lib: sbi: Add system_suspend_allowed domain property

Only privileged domains should be allowed to suspend the entire system. Give the root domain this property by default and allow other domains to be given the property by specifying it in the DT. Signed-off-by: Andrew Jones Reviewed-by: Anup Patel

With the existing DT example in the doc OpenSBI won't boot anymore. Let's update the DT example so that it can work out of the box. Signed-off-by: Bin Meng Reviewed-by: Anup Patel
