feat(lfa): harden cancel handling and lock around LFA_CANCEL

2026-06-30T20:25:11+00:00

- block cancel once all active CPUs have entered ACTIVATE - take lfa_lock during cancel SMC handling Change-Id: I1443644845d19e0322f5d188461a1c4083c57707 Signed-off-by: Manish V Badarkhe Signed-off-by: John Powell

feat(lfa): serialize activate across CPUs and manage rendezvous policy

2026-06-30T20:25:03+00:00

Track activation state across CPUs so skip-rendezvous activations don’t block or interleave. Split activate into prepare/finish to latch the rendezvous policy, notify the platform once per activation, and only clear activation_pending after all callers finish. Return LFA_BUSY for conflicting skip requests and LFA_CALL_AGAIN for multi‑stage activations.

feat(lfa): lfa service updates

2026-06-30T15:42:43+00:00

This patch updates the LFA service components in preparation for BL31 specific changes. Change-Id: I6d4dd90b11fa1d8729c4f9026d2ddce0272aea76 Signed-off-by: John Powell

fix(lfa): validate component_id before activation check

2026-04-28T09:27:20+00:00

Reorder checks so component_id is validated before indexing lfa_components. Prevents out-of-range access when an invalid component_id is passed while activation is not pending. Change-Id: Ia0ae60d95c07840dfdc52ce0b4f7e511a28541bc Signed-off-by: Manish V Badarkhe Signed-off-by: Ashutosh Desai

fix(lfa): update activation_pending flag on SUCCESS

2026-02-25T22:03:58+00:00

This patch updates the 'activation_pending' only if the activator was able to successfully activate the component. The expectation is that the caller will either re-issue the activation or issue the LFA_CANCEL command. Change-Id: I1079a544adfbb90c7189e98a4fac991273a2fe30 Signed-off-by: Varun Wadekar

feat(lfa): introduce support for call_again for LFA_PRIME

2025-11-06T15:48:12+00:00

LFA_PRIME is a single-threaded operation that is not pinned to a specific CPU. The implementation must support calls being issued from different CPUs, even for several calls to prime the same component. This patch checks if the plat_lfa_load_auth_image return -EAGAIN indicating that the platform expects the LFA_PRIME call to be issued again. This is done by returning LFA_SUCCESS and setting flags[0] to 1, indicating that LFA_PRIME is incomplete and must be called again.

feat(lfa): allow LFA_PRIME from one CPU at a time

2025-11-06T11:24:59+00:00

LFA_PRIME is a single-threaded operation that is not pinned to a specific CPU. The implementation must support calls being issued from different CPUs, even for several calls to prime the same component. However, those calls must not happen concurrently. This patch introduces a spinlock across the LFA_PRIME call to support this requirement. In case of concurrent calls, the LFA_BUSY error code is returned to the caller.

chore(lfa): rename component_id to lfa_component_id

2025-10-22T08:01:03+00:00

Refactor the function lfa_is_prime_complete to use a more specific parameter name, lfa_component_id, enhancing code clarity. This change improves readability and reduces potential confusion with other component identifiers in the codebase.

fix(lfa): check error code from plat_lfa_load_auth_image

2025-10-14T16:14:15+00:00

This patch checks the return values from plat_lfa_load_auth_image and returns an LFA* error code to the caller, if required. Change-Id: I7c1cad8e5f24b0e4cfdf2667adeed30c4d33bda0 Signed-off-by: Varun Wadekar
