lib: sbi: Allow ecall handlers to directly update register state

2023-12-19T10:26:37Z

Some of the upcoming SBI extensions (such as SSE) will directly update register state so improve the prototype of ecall handler to accommodate this. Further, this flexibility allows us to push the trap redirection from sbi_ecall_handler() to the sbi_ecall_legacy_handler(). Signed-off-by: Anup Patel

platform: Allow platforms to specify the size of tlb fifo

2023-09-10T05:51:05Z

For some platforms with a particularly high number of harts, if the tlb fifo is too small, it case harts to wait. Platforms should be allowed to specify the size of the tlb fifo. Signed-off-by: Xiang W Signed-off-by: Xing Xiaoguang Reviewed-by: Anup Patel

include: sbi: Remove extid parameter from vendor_ext_provider() callback

lib: sbi: Align SBI vendor extension id with mvendorid CSR

2023-02-27T05:56:35Z

As-per the SBI specification, the lower 24bits of the SBI vendor extension id is same as lower 24bits of the mvendorid CSR. We update the SBI vendor extension id checking based on above. Signed-off-by: Anup Patel

lib: sbi: Simplify system reset platform operations

2021-04-28T11:55:00Z

Instead of having system_reset_check() and system_reset() callbacks in platform operations, it will be much simpler for reset driver to directly register these operations as a device to the sbi_system implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis
