include: sbi: Add SBI MPXY notification related defines

2026-06-10T12:43:10Z

The SBI MPXY notification header related offsets are missing from the sbi_ecall_interface.h hence add these defines. Signed-off-by: David E. Garcia Porras Signed-off-by: Anup Patel Link: https://lore.kernel.org/r/20260608125257.3220114-5-anup.patel@oss.qualcomm.com Signed-off-by: Anup Patel

lib: sbi: Fix undefined behavior in signed shifts in sbi_hart.c

2026-03-09T06:43:20Z

UBSan detected undefined behavior in sbi_hart.c and sbi_fwft.c (in the case of sbi_fwft.c, the bug comes from a macro call defined at sbi_ecall_interface.h) caused by shifting a signed integer into the sign bit (1 << 31) This can be fixed by using the 1UL literal, ensuring defined arithmetic. Please let me know if there’s any other most suitable solution for this bug.

lib: sbi_pmu: Fix xINH bits configuring

2025-12-01T05:36:36Z

Before this patch sbi_pmu_ctr_start() ignores flags received in sbi_pmu_ctr_cfg_match() including inhibit ones. To prevent it, save flags together with event_data and use them both in sbi_pmu_ctr_start().

lib: sbi: sse: Add support for SSTATUS.SDT

2025-03-27T12:46:44Z

Similarly to what is done for SPELP, handle SSTATUS.SDT upon event injection. In order to mimick an interrupt, set SDT to 1 for injection and save its previous value in interrupted_flags[5:5]. Restore it upon completion. Signed-off-by: Clément Léger Reviewed-by: Andrew Jones

lib: sbi: sse: Add support for SSTATUS.SPELP

2025-03-27T12:46:28Z

As raised during the ARC review, SPELP was not handled during the event injection process. Save it as part of the interrupted flags, clear it before injecting the event and restore it after completion. Signed-off-by: Clément Léger Reviewed-by: Andrew Jones

lib: sbi: sse: Rename STATUS* interrupted flags to SSTATUS*

2025-03-27T12:45:44Z

As raised by Andrew on the kvm-unit-test review, this flags are meant to hold SSTATUS bits in the specification. Rename them to match that. Signed-off-by: Clément Léger Reviewed-by: Andrew Jones

lib: sbi: sse: Update SSE event ids

The latest specification added new high priority RAS events and renamed the PMU to PMU_OVERFLOW. Signed-off-by: Clément Léger Reviewed-by: Andrew Jones

lib: add tests for sbi_ecall functionality

2025-03-23T11:26:54Z

This patch adds unit tests for verifying the sbi_ecall version, impid handling, and extension registration functions. The tests ensure that the extension registration and unregistration work as expected. Signed-off-by: Akshay Behl Reviewed-by: Anup Patel
