lib: utils: Fix irqchip registration for PLIC and APLIC

2024-12-24T08:36:09Z

Currently, the same irqchip instance is registered for multiple PLIC and APLIC instances which causes the sbi_list_for_each_entry() loop in the sbi_irqchip_init() to hang at boot-time. To address the above issue, register a separate irqchip instance for each PLIC and APLIC instance.

lib: utils: Mark RPMI drivers as experimental

2024-12-21T12:52:47Z

These drivers were merged on an experimental basis without the RPMI specification being frozen. As a result, they may not be compatible with the frozen version of the RPMI protocol. Additionally, their devicetree bindings have not been reviewed and are subject to change. Warn the user that these drivers make no compatibility guarantees, and that their behavior and devicetree bindings may change incompatibly in future versions of OpenSBI.

lib: sbi_pmu: Verify the raw events first during event info

2024-12-15T08:43:12Z

The raw events have same event_idx. Thus, the event info sanity check only relies on the select mask. The raw event check should be done first so that regular hardware events can be verified using event idx range check.

2024-12-15T08:36:52Z

The hardware event map function invoked from platform code should exclude any raw events as there is a separate function for the raw events. Fixes: d8a483fc7fd0 ("lib: sbi_pmu: PMU raw event v2 support") Signed-off-by: Atish Patra Reviewed-by: Anup Patel

Makefile: Don't enable V-extension using -march option

2024-12-15T06:00:48Z

Enabling V-extension using -march option causes OpenSBI boot-time hang with LLVM compiler. As a work-around, don't enable V-extension using -march option and instead use a custom OpenSBI specific define inform availability of V-extension to lib/sbi/sbi_trap_v_ldst.c.
