I think that if QEMU isn't providing the PSCI implementation it shouldn't advertise it in the ACPI tables. It would seem more logical that the firmware itself does that (QEMU can't know if it really does provide PSCI, after all...) thanks -- PMM

Hi Peter, Yes, your considerations reasonable. But in practice of hardware platforms, programmer checks that Arm TF is using SMC for PSCI call conduit, then fix it manually in the ACPI table, reason may be that Arm TF is lack of ACPI support, if device tree used, there should be no such thing because Arm TF can support it. On QEMU, I just mimic the situation, if a complete reasonable solution, further efforts are needed to figure it out.

I'm afraid I don't really understand what you're saying here. Could you try rephrasing it? If we're running at EL3 and booting firmware, then QEMU doesn't provide PSCI. The firmware we're booting is the only thing that can know if that firmware has implemented PSCI. So only it can decide whether the ACPI tables and DTB should say that PSCI is present. thanks -- PMM

Agree with your comments, I hope ACPI's psci conduit node can reflect firmware's implementation, even when firmware PSCI conduit changes, ACPI node changes accordingly. But for ACPI and DTB, there are different situations now. If DTB is used, firmware(with psci implementation) can generate DTB nodes, saying which PSCI conduit is used - smc or hvc, then uboot or uefi can get this DTB add more DTB nodes before transfer it to kernel. That is, using DTB, we can achieve the goal. But when ACPI used, there is no codes in firmware to generate ACPI node to show which PSCI conduit is used, then uefi or later stage cannot get this info dynamically from any codes as far as I know. (this is why programmer manually check that firmware is using smc, then write a fixed value in ACPI FADT). So, if we want to fix this neatly, adding ACPI support in Arm trusted firmware may be the solution, but it should be a big feature for firmware, not QEMU.

I think my view here remains the same. QEMU does not and cannot know what the EL3 firmware is providing for a PSCI conduit. So it can't put anything in the ACPI table fragments. It has to be up to the guest code at EL3 to determine the right answer and put it in the ACPI table or DT that gets used at EL1 or EL2. thanks -- PMM

When QEMU_PSCI_CONDUIT_DISABLED is set, it doesn't mean all the PSCI conduits are totally disabled, it only mean the QEMU built-in PSCI support is disabled, in such a case, e.g. EL3 is enabled and external firmware (it is usually Arm Trusted Firmware) is loaded, SMC should be used for the guest to trigger PSCI functions.
