lib: sbi: add support for firmware features extension

2024-06-19T12:39:22Z

This extension allows the software running in supervisor mode to control the behavior of various features of the SBI [1]. Implement the support for such extension. Link: https://lists.riscv.org/g/tech-prs/message/924 [1] Signed-off-by: Clément Léger Reviewed-by: Anup Patel

lib: sbi: Add support for Svade and Svadu extensions

2024-06-18T11:11:32Z

Add support for Svade and Svadu extensions. When both are present in the device tree, the M-mode firmware should select the Svade extension to comply with the RVA23 profile, which mandates Svade and lists Svadu as an optional extension. Signed-off-by: Yong-Xuan Wang Reviewed-by: Anup Patel

sbi: sbi_domain_context: Fix trap context for domain context switching

2024-06-13T13:51:27Z

Save/restore sbi_trap_context during domain context switching to ensure proper trap handling and isolation. This maintains correct domain-specific state, avoiding context corruption.

sbi: sbi_domain_context: Add spinlock for updating domain assigned_harts

2024-05-07T14:41:30Z

Add spinlock protection to avoid race condition on assigned_harts during domain context switching. Also, rename/add variables for accessing the corresponding domain of target/current context. Signed-off-by: Alvin Chang Reviewed-by: Yu Chien Peter Lin Reviewed-by: Anup Patel

lib: sbi: sse: fix typos, comments and spacing errors

Fix some errors spotted by Samuel while reviewing the SSE implementation. Signed-off-by: Clément Léger Reported-by: Samuel Holland Reviewed-by: Anup Patel

lib: tests: Add test suite init function

2024-05-07T05:57:13Z

Allow to define an init function for the test suite. It could help us to initialize global variable once, and use them in multiple test cases after the initialization. For instance, if multiple test cases use the same atomic_t var, it could be helpful to call ATOMIC_INIT once during the suite initialization. Signed-off-by: Ivan Orlov Reviewed-by: Anup Patel

lib: sbi: Simplify wait_for_coldboot() implementation

2024-04-05T12:18:23Z

On QEMU virt machine with large number of HARTs, some of the HARTs randomly fail to come out of wait_for_coldboot() due to one of the following race-conditions: 1) Failing HARTs are not able to acquire the coldboot_lock and update the coldboot_hartmask in wait_for_coldboot() before the coldboot HART acquires the coldboot_lock and sends IPI in wake_coldboot_harts() hence the failing HARTs never receive IPI from the coldboot HART. 2) Failing HARTs acquire the coldbood_lock and update the coldboot_hartmask before coldboot HART does sbi_scratch_init() so the sbi_hartmask_set_hartid() does not update the coldboot_hartmask on the failing HARTs hence they never receive IPI from the coldboot HART. To address this, use a simple busy-loop in wait_for_coldboot() for polling on coldboot_done flag. Signed-off-by: Anup Patel
