TF-A Tech Forum on June 12th 2025 - TF-RMM live activation

by Olivier Deprez

Hi, On June 12th 2025, the TF-A Tech forum will take place at 4.00pm UK with the following topic: TF-RMM live activation design discussion Presenters: Andre Przywara Soby Mathew Manish Badarkhe In this meeting, we aim to discuss the details of live firmware activation for TF-RMM. The key topics will include: * Design details of TF-RMM live activation * Rationale for EL3-RMM communication changes: We will explain the motivation behind the proposed changes to the communication mechanism between EL3 and RMM which simplifies internal state migration for LFA, enables sharing of the state across RMM instances that are live-activated, supports localized per-CPU allocations for NUMA and multi-chip configurations, decouples the RMM binary from platform-specifics. * LFA SMC Implementation in EL3: We will also provide an overview of the LFA SMC implementation at EL3. Regards, Olivier.

FVP_Base_Cortex-A520 crash

by shaunak saha

Hi All, I'm new to TF-A. While working on enabling Linux on A-520 FVP, I ran into an issue that I wanted to ask about. My stack looks like this:TF-A->U-boot->kernel. Initially I was able to boot on Base FVP(FVP_Base_RevC-2xAEMvA) and get to the linux console. Now we need to enable the same for A-520 FVP as our soc will be A-520. I saw the crash happening very early in "cpu_helpers.S. I made the change in plat/arm/board/fvp/platform.mk by adding lib/cpus/aarch64/cortex_a520.S in one of the FVP_CPU_LIBS and enabling the ERRATA_A520_2938996, ERRATA_A520_2858100 and ERRATA_A520_2630792. These changes helped me get past the TF-A and now i ' m seeing a crash inside kernel in pci. 16.720973] pci-host-generic 40000000.pci: host bridge /pci@40000000 ranges: [ 16.721375] pci-host-generic 40000000.pci: MEM 0x0050000000..0x005fffffff -> 0x0050000000 [ 16.722013] pci-host-generic 40000000.pci: ECAM at [mem 0x40000000-0x4fffffff] for [bus 00-ff] [ 16.723128] pci-host-generic 40000000.pci: PCI host bridge to bus 0000:00 [ 16.723461] pci_bus 0000:00: root bus resource [bus 00-ff] [ 16.723761] pci_bus 0000:00: root bus resource [mem 0x50000000-0x5fffffff] [ 16.724101] Internal error: synchronous external abort: 0000000096000010 [#1] SMP [ 16.724216] Modules linked in: [ 16.724302] CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.15.0-rc7-dirty #12 PREEMPT [ 16.724449] Hardware name: FVP Base RevC (DT) [ 16.724531] pstate: 214000c9 (nzCv daIF +PAN -UAO -TCO +DIT -SSBS BTYPE=--) [ 16.724666] pc : pci_generic_config_read+0x38/0xb8 [ 16.724802] lr : pci_generic_config_read+0x24/0xb8 [ 16.724939] sp : ffff80008272b940 [ 16.725012] x29: ffff80008272b940 x28: 0000000000000000 x27: ffff800081dc00b0 [ 16.725205] x26: ffff800081ec9060 x25: ffff800081ec9078 x24: ffff80008266a9a0 [ 16.725401] x23: 0000000000000000 x22: ffff80008272b9f4 x21: ffff000800fa8000 [ 16.725594] x20: ffff80008272b964 x19: 0000000000000004 x18: 0000000000000006 [ 16.725781] x17: 6666666666663478 x16: 302d303030303030 x15: ffff800082edbbbf [ 16.725980] x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000000 [ 16.726166] x11: 0000000000000001 x10: 3ea1f6d484b7e318 x9 : 69631046f78aed23 [ 16.726355] x8 : ffff000800169108 x7 : ffff800082250960 x6 : 00000000000000ff [ 16.726547] x5 : 0000000000000000 x4 : 0000000000000000 x3 : ffff800090000000 [ 16.726738] x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff800090000000 Do i need to do enable somethign else in TF-A?

I’d really appreciate any guidance or pointers, and if this is a known issue or good for a first-time contributor, I’d be happy to help. Regards, Shaunak
