include: sbi_bitops: More useful bit operations

2020-03-08T05:39:46Z

This patch extends our bit operation library with mechanism to: 1. Iteratively traverse bits 2. Set bit 3. Clear bit 4. Change bit 5. ... other helpful functions ... Most the above is adopted from Xvisor sources. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: Move bits related defines and macros to sbi_bitops.h

2020-03-08T05:36:18Z

The right location for all bits related defines and macros is sbi_bitops.h hence this patch. With this patch, the sbi_bits.h is redundant so we remove it. 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.
