Firmware-A v2.12 release code freeze notification

by Govindraj Raja

Hi All, The next release of the Firmware-A bundle of projects tagged v2.12 has an expected code freeze date of Nov, 8th 2024. Refer to the release cadence section from TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…). Closing out the release takes around 6-10 working days after the code freeze. v2.12 release preparation tasks start from now. We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. As a kind recommendation and a matter of sharing CI resources, please launch CI jobs with care e.g.: -For simple platform, docs changes, or one liners, use Allow-CI+1 label (no need for a full Allow-CI+2 run). -For large patch stacks use Allow-CI+2 at top of the patch stack (and if required few individual Allow+CI+1 labels in the middle of the patch stack). -Carefully analyze results and fix the change if required, before launching new jobs on the same change. -If after issuing a Allow-CI+1 or Allow-CI+2 label a Build start notice is not added as a gerrit comment on the patch right away please be patient as under heavy load CI jobs can be queued and in extreme conditions it can be over an hour before the Build start notice is issued. Issuing another Allow-CI+1 or Allow-CI+2 label will just result in an additional job being queued. -- Thanks, Govindraj R

Re: TF-A Tech Forum regular call

by Olivier Deprez

+ other MLs ________________________________ From: Olivier Deprez Sent: 30 October 2024 11:41 To: tf-a(a)lists.trustedfirmware.org <tf-a(a)lists.trustedfirmware.org> Subject: TF-A Tech Forum regular call Dear TF-A ML members, As mentioned in https://www.trustedfirmware.org/meetings/tf-a-technical-forum/, trustedfirmware.org hosts regular technical calls on Thursdays. It mentions TF-A although in practise a number of Cortex-A projects beyond TF-A were discussed (refer to prior recordings on this page). Unfortunately this slot hasn't been very active recently. By this email I'm kindly emphasizing this forum is open to the community (and beyond trustedfirmware.org members) and you are welcome to propose topics. Presentations/slides are not strictly necessary, and we can also host informal discussions or session of questions. If you think of a topic, please reach to me and I'll be happy to accommodate. Thanks for your contributions in advance! Regards, Olivier.

Current status of NWd driver for secondary VM SMP support

by Sungbae Yoo

Hi, I have a couple of question about SMP support of linux driver. We'd like to run multiple SP that uses secondary cores. The first SP can initialize all secondary vCPUs when linux invokes cpu on for all secondary cores. But the other SP doesn't initialize its secondary vCPUs. If My understanding is correct, they will be initialized when FFA_RUN calls to each vCPUs are called [1] and FFA_RUN calls are called by Normal world driver in linux [2]. But I can't find any implementations regarding this in the latest upstream linux (v6.10). Actually, I found ffa_cpu_ops in linux code [3], but couldn't the place where it is used. I think that ffa_run has to be called in driver to initialize secodary vCPUs of secondary VMs. Am I missing something in the code? Or Is there no implementation yet in upstream? I'd like to know about the current status of secondary VM SMP support in linux. If linux driver doesn't support it yet, Do you have any plan to make an implementation and merge it? Thanks, Sungbae Yoo.

Could you add a new gicd_set_ctlr() API to set GICD_CTLR to wait until RWP becomes zero?

by magicse7en＠outlook.com

Hi , Could you add below patch to gicv3_helpers.h? --- a/src/arch/aarch64/plat/interrupts/gicv3_helpers.h +++ b/src/arch/aarch64/plat/interrupts/gicv3_helpers.h @@ -203,6 +203,16 @@ static inline void gicd_wait_for_pending_write(uintptr_t gicd_base) } } +static inline void gicd_set_ctlr(uintptr_t base, + unsigned int bitmap, + unsigned int rwp) +{ + gicd_write_ctlr(base, gicd_read_ctlr(base) | bitmap); + if (rwp != 0U) { + gicd_wait_for_pending_write(base); + } +} + static inline uint32_t gicd_read_pidr2(uintptr_t base) { return io_read32(IO32_C(base + GICD_PIDR2_GICV3)); The existed gicd_write_ctlr() just write the GICD_CTLR, but from GIC spec, if write GICD_CTLR, it needs to wait the RWP bit becomes zero. Therefore, I think the gicd_set_ctlr() function of tf-a is a good choice. I tried to push this patch to https://review.trustedfirmware.org/, but I encountered below error. error: RPC failed; HTTP 403 curl 22 The requested URL returned error: 403

Hafnium - number of PEs vs number of VCPU

by Pawandeep Oza (QUIC)

Hi, I have a question about hafnium executing PSCI_CPU_ON. So what I observe is, if I define single SP with 2 Physical CPUs & 2 VCPUS defined in SPMC manifest for hypervisor and secure partition, respectively. And when I do have > 2 cpus running in non-secure world, precisely at the moment when Linux brings up 3rd CPU with PSCI_CPU_ON, EL3 PSCI calls will be forwarded to hafnium running in secure EL2. And this is where it hits. And since hafnium doesn't find 3rd CPU defined in manifest it will hit "Dead stop here if no more CPU. */ .global cpu_entry cpu_entry: #if SECURE_WORLD == 1 /* Get number of cpus gathered from DT. */ adrp x3, cpu_count add x3, x3, :lo12:cpu_count ldr w3, [x3] /* Prevent number of CPUs to be higher than supported by platform. */ cmp w3, #MAX_CPUS bhi . /* x0 points to first cpu in cpus array. */ adrp x0, cpus add x0, x0, :lo12:cpus /* Get current core affinity. */ get_core_affinity x1, x2 /* Dead stop here if no more cpu. */ 0: cbz w3, 0b sub w3, w3, #1 /* Get cpu id pointed to by x0 in cpu array. */ ldr x2, [x0, CPU_ID] If I have defined this 3rd physical CPU in hafnium manifest then hafniu proceed further from above code. But then will hit plat_psci_cpu_resume and eventually it will abort with following check CHECK(vcpu_index < vm->vcpu_count); cpu_init: /* Call into C code, x0 holds the CPU pointer. */ bl cpu_main /* Run the vCPU returned by cpu_main. */ bl vcpu_restore_all_and_run it looks like hafnium expects >= the number of physical Pes running at non-secure side to be defined in SPMC manifest file. Also it expects the same number of VCPUs to be defined in manifest file. but my understanding is, there could be number of PEs running at non-secure side could be greater than number of Pes/VCPUs at secure side. But from the code flow of hafnium, I don't think it supports that. Regards, Oza.
