This fixes various coding style issues found in the SBI codes. No functional changes. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

lib: Introduce sbi_ipi_event_create/destroy() APIs

2020-01-22T06:40:44+00:00

This patch introduces sbi_ipi_event_create/destroy() APIs and struct sbi_ipi_event_ops for creating/destroying IPI events at runtime based of event operations. This new APIs will help platform code and utils code to create custom IPI events which are not part of generic OpenSBI library. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Introduce sbi_ipi_send_halt() API

2020-01-22T06:40:37+00:00

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: Introduce sbi_ipi_send_smode() API

2020-01-22T06:40:35+00:00

Instead of directly calling sbi_ipi_send_many(), we introduce sbi_ipi_send_smode() for injecting S-mode software interrupts. This way in future we can assign any IPI event number for S-mode IPIs within sbi_ipi.c only. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Move struct sbi_ipi_data definition to sbi_ipi.c

2020-01-22T06:40:33+00:00

The struct sbi_ipi_data is only used in sbi_ipi.c so move it to sbi_ipi.c from sbi_ipi.h. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Add ipi exit API

2020-01-07T06:41:02+00:00

We add sbi_ipi_exit() API for exit path handling in sbi_exit() implementation. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Add IPI extension in SBI

2019-12-23T03:42:13+00:00

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.

lib: Remove redundant IPI types

2019-12-23T03:42:08+00:00

We just need to distinguish only between FENCE and non FENCE related IPIs as all of the fence related requests are handled via fifo now. Remove the unnecessary IPI types related to individual fence types. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

lib: Better naming of unpriv APIs for wider use

2019-11-21T08:27:33+00:00

The unpriv APIs can be useful to external firmware and out-of-tree platform support code. This patch adds "sbi_" prefix to unpriv load/store APIs and rename struct riscv_unpriv to struct sbi_trap_info everywhere. We also place struct sbi_trap_info in sbi/sbi_trap.h so that we can use it for sbi_trap_redirect() as well. Overall, this patch will make naming of unpriv APIs consistent with other OpenSBI APIs.
