lib: sbi_domain: Use domain data support for per-domain hart context

2024-10-25T17:30:10Z

The per-domain hartindex_to_context_table[] is yet another per-domain data required for implementing hart entry into (or exit from) domain. Use the recently added domain data support for per-domain hart context so that a dedicated hartindex_to_context_table[] in struct sbi_domain is not needed.

The sbi_domain_context.h includes sbi_domain.h and the sbi_domain.h also includes sbi_domain_context.h. Remove this cyclic include in sbi_domain_context.h. Signed-off-by: Anup Patel Reviewed-by: Samuel Holland

lib: sbi: Use current_hartindex() where possible

This avoids calls to the expensive sbi_hartid_to_hartindex() function and also makes the firmware smaller. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

sbi: sbi_domain_context: Fix trap context for domain context switching

2024-06-13T13:51:27Z

Save/restore sbi_trap_context during domain context switching to ensure proper trap handling and isolation. This maintains correct domain-specific state, avoiding context corruption.

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.
