Deprecation notification of Socionext Uniphier, Arm fvp_ve, Broadcom Stingray platforms

by Boyan Karatotev

Hello, During a recent code ownership cleanup we have identified three platforms that lack designated code owners: Socionext Uniphier, Arm fvp_ve, Broadcom Stingray platforms. All three have not had any significant activity for some time now and as such we are going to mark them as deprecated. The patches to do that are here: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/53842. We will go ahead with them in the next week or so unless we hear any objections. These platforms will not be removed until after the next v2.16 release scheduled for later this year. We will not proceed with removal if code owners are found before then. Thanks, Boyan

SDEI: SDEI_EVENT_0 trigger dropped while PE masked — by design?

by wtliang785

Hi all, I'd like to ask whether the following behavior of SDEI_EVENT_0 is intended, and whether it's a known limitation of the SDEI + GIC SGI semantics. I've read the code carefully but want to confirm the intent before relying on or working around it. ## Setup - TF-A SDEI, event 0 is a "signalable" private event whose backing interrupt is a Secure SGI (on our platform, SGI 9). - include/services/sdei.h, SDEI_DEFINE_EVENT_0(_intr) -> SDEI_PRIVATE_EVENT(SDEI_EVENT_0, _intr, SDEI_MAPF_SIGNALABLE) - services/std_svc/sdei/sdei_main.c: asserts event 0 must be a Secure SGI and may only carry SIGNALABLE|PRIVATE. ## What I observe in code When the PE is SDEI-masked (client called SDEI_PE_MASK) and the SGI backing event 0 fires, the handler does *not* preserve the trigger: 1. The EL3 FIQ is taken and acked in bl31/ehf.c ehf_el3_interrupt_handler() via plat_ic_acknowledge_interrupt() (reads ICC_IAR — interrupt now Active, its Pending bit consumed). 2. It reaches sdei_intr_handler() (services/std_svc/sdei/sdei_intr_mgmt.c). At L463, state->pe_masked is true, so it calls handle_masked_trigger() and returns 0. 3. handle_masked_trigger() : /* Nothing to do for event 0 */ if (map->ev_num == SDEI_EVENT_0) return; i.e. for event 0 it does none of the "freeze for replay" steps that a normal private event takes : plat_ic_disable_interrupt(intr); plat_ic_set_interrupt_pending(intr); plat_ic_end_of_interrupt(intr_raw); state->pending_enables = true; So while the PE is masked, an event-0 trigger is acknowledged and then silently dropped, with nothing stored for replay on the next SDEI_PE_UNMASK. ## Why I think this happens (and want to confirm) The "freeze for replay" mechanism for normal private events relies on re-asserting Pending via plat_ic_set_interrupt_pending(), because the ack already consumed the Pending bit. But for an SGI this is not permitted — plat/common/plat_gicv3.c: asserts it out: void plat_ic_set_interrupt_pending(unsigned int id) { /* Disallow setting SGIs pending */ assert(id >= MIN_PPI_ID); gicv3_set_interrupt_pending(id, plat_my_core_pos()); } So event 0 (backed by an SGI) cannot have its Pending bit re-asserted in software, which is consistent with the "Nothing to do for event 0" early return. Combined with the level/merge semantics of GIC SGIs (a sender firing the same SGI N times is represented as a single Pending, not a count), this means a masked-PE client can at most learn "an event happened while masked", never how many or which — by design. ## My questions 1. Is dropping an event-0 trigger while the PE is masked the intended behaviour (a consequence of "event 0 is a signalable SGI, counting is not guaranteed"), rather than a bug? The "Nothing to do for event 0" comment reads as deliberate, but I'd like explicit confirmation. 2. Is the recommended mitigation simply to avoid firing event 0 while the PE is masked (buffer on the sender side, deliver after unmask), or to use a normal explicit event for anything requiring precise accounting? Or is there a platform hook intended for this case that I'm missing (e.g. plat_sdei_handle_masked_trigger — though that path is only taken for shared ANY-PE events , not event 0)? 3. Separately (not the focus of this question): on this masked path neither handle_masked_trigger() nor sdei_intr_handler() calls plat_ic_end_of_interrupt() for event 0, and neither the EHF top-level handler nor the runtime_exceptions.S dispatch macro performs a fallback EOI. So the acked SGI appears to be left Active with no EOI on this path. Is there a later EOI for this SGI that I've missed, or is that also expected here? I don't want to conflate this with the "drop" question above; I'm just flagging it. For reference, this is on an in-tree SDEI path; the platform only defines event 0 via SDEI_DEFINE_EVENT_0(PLAT_SDEI_SGI_PRIVATE) and does not modify handle_masked_trigger(). Thanks, Tianliang
