[edk2-devel] SbsaQemu: SIP_SVC_GET_CPU_TOPOLOGY call failed (need updated binaries in edk2-non-osi?)

[Rebecca Cran via groups.io]

Do the TF-A binaries in edk2-non-osi need updated for SbsaQemu?

With the binaries in Platform/Qemu/Sbsa I get the following error during 
boot:

GetCpuCount: We have 4 cpus.
GetMpidr: MPIDR for CPU0: = 0
GetMpidr: MPIDR for CPU1: = 1
GetMpidr: MPIDR for CPU2: = 2
GetMpidr: MPIDR for CPU3: = 3
GetCpuCount: We have 4 cpus.
ERROR:   sbsa_sip_smc_handler: unhandled SMC (0xc20000ca) (function id: 202)
GetCpuTopology: SIP_SVC_GET_CPU_TOPOLOGY call failed. We have no cpu 
topology information.


If I update the binaries with a fresh set built from TF-A commit 
8e9bdc5b1d65f49546afbe97943d263a1332e67e it successfully boots to the 
UEFI Shell.

Ops, forgot to update binaries. Sent patch for review.

QemuSbsa needs QEMU 9.x or later. Especially this commit:

Subject: [PATCH] hw/arm/sbsa-ref: Enable CPU cluster on ARM sbsa machine

Enable CPU cluster support on SbsaQemu platform, so that users can
specify a 4-level CPU hierarchy sockets/clusters/cores/threads. And
this topology can be passed to the firmware through /cpus/topology
Device Tree.

==========================

Without it we do not have topology information and machine stops.
