lib: Introduce sbi_ipi_send_halt() API

2020-01-22T06:40:37Z

Instead of directly calling sbi_ipi_send_many(), we introduce sbi_ipi_send_halt() for halting a set of HARTs. This way in future we can assign any IPI event number for HART halting within sbi_ipi.c only. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: improve system reboot and shutdown implementation

2020-01-07T06:41:36Z

We improve sbi_system_reboot() an sbi_system_shutdown() by: 1. Calling halt IPI to all harts (except current HART) before calling platform reboot/shutdown hook. 2. Calling sbi_exit() instead of sbi_hang() in-case platform reboot/shutdown hook failed. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Add system early_exit and final_exit APIs

2020-01-07T06:40:48Z

This patch adds system-level early_exit and final_exit APIs with corresponding platform hooks. These new APIs will be primarily used by sbi_exit() in OpenSBI exit path. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Add IPI extension in SBI

2019-12-23T03:42:13Z

This patch adds new IPI extension which replaces ipi related v0.1 extensions. This also adds a new API for ipi sending as trap handling is not necessary in v0.2 SBI IPI related extensions. It also modifies the IPI sending code which now accepts hart mask as a value instead of S-mode virtual address. Thus, the caller should set it to exact hart mask value everytime.
