lib: Print interrupt and exception delegation in boot prints

2020-02-19T04:28:48Z

We print MIDELEG and MEDELEG CSRs as part of boot prints so that boot log shows the interrupts and exceptions delegated to S-mode. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Atish Patra

lib: Add dynamic registration of SBI extensions

2020-01-22T06:43:34Z

This patch extends our SBI ecall implementation to allow dynamic registration of various SBI extensions. Using this dynamic registration we can break-up SBI ecall implementation into multiple files and even register experimental/custom SBI extensions from platform code.

lib: Initialize TLB management directly from coldboot/warmboot path

2020-01-22T06:40:49Z

Currently, the remote TLB management is initialized via IPI init which is counter intuitive. This patch initializes remote TLB management directly from init_coldboot() and init_warmboot() after IPI init is done. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Add sbi_init_count() API

2020-01-07T06:41:48Z

We add sbi_init_count() API which provides number of times a given HART completed init sequence (warmboot/coldboot). This will be very useful in debugging. With upcoming SBI HSM extension, it will also help in implementing one-time init code for each HART. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Add irqchip exit API

2020-01-07T06:41:19Z

We add an optional platform irqchip exit hook for exit path handling in sbi_exit() implementation. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Add ipi exit API

2020-01-07T06:41:02Z

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 timer exit API

2020-01-07T06:40:55Z

We add sbi_timer_exit() API for OpenSBI exit path handling in sbi_exit() implementation. 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 initial sbi_exit() API

2020-01-07T06:40:35Z

This patch adds initial implementation of sbi_exit() API which can be used to perform OpenSBI exit sequence for current HART. The sbi_exit() implementation will be further extended by subsequent patches. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Remove unnecessary checks from init_coldboot() and init_warmboot()

2020-01-07T04:52:24Z

We remove unnecessary checks related to hart hotplug and disabled hart in coldboot and warmboot init path. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
