lib: sbi: Improve the alignment of boot-time prints

2024-12-24T06:30:47Z

Addition of "Experimental SBI Extensions" to the boot-time prints disturbs the alignment of other prints so adjust all boot-time prints accordingly. Signed-off-by: Anup Patel

lib: sbi: Print list of available SBI extensions at boot-time

2024-12-22T05:46:13Z

Add boot-time prints for list of available standard and experimental SBI extensions. Signed-off-by: Anup Patel

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.

lib: sbi_pmu: Fix the sanity check condition for hw event map

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

lib: sbi: sse: Fix a6 and a7 register content upon injection

2024-12-15T06:23:53Z

The specification states that a6 contains the current hart id and a7 contains the entry argument. This was inverted in the current implementation. Reported-by: Andrew Jones Signed-off-by: Clément Léger 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.

lib: sbi_misaligned_ldst: Add handling of vector load/store

2024-12-06T12:13:06Z

Add misaligned load/store handling for the vector extension to the sbi_misaligned_ldst library. This implementation is inspired from the misaligned_vec_ldst implementation in the riscv-pk project.

lib: sbi: Add SBI Message Proxy (MPXY) framework

2024-12-06T03:56:50Z

Introduce SBI Message Proxy (MPXY) framework which allows platform specific code or drivers to register message protocol specific channels. This framework enables the supervisor software to send messages belonging to different message protocols via OpenSBI firmware.
