Does FVP_Base_RevC-2xAEMvA platform model has a full support for address translation at PL2 stage-1 MMU in aarch32?

by Marek

Have you ever succeeded in performing a Stage-1 MMU translation using LPAE (Long Physical Address Extension) on the FVP_Base_RevC-2xAEMvA platform model running in AArch32 Hyp mode (CONFIG64=0) into any other Memory but Strongly-Ordered? My environment is - FVP_Base_RevC-2xAEMvA booting SW stack from bullet point below - SW stack from Yocto, 'meta-arm'. I use 'fvp-base-arm32' that builds bl1, bl2, bl32, bl33, Linux kernel and rootfs. The only component that works there at PL2 HYP mode is u-boot (bl33). Whichever attributes I assign there Normal Memory with Inner or Outer Cacheability, Write-Through, or Write-Back, or Non-cacheable I always end up with Strongly-Ordered. To me it looks like it doesn't read the MAIR correctly and/or ignores the Cachability in HCTR. I inspected the MMU code thoroughly there, compared with the other codes for MMU, from trusted-firmware-a, xen, and Linux kernel and it seems u-boot does it correct. U-boot sets there identity-mapping for all 4GB with 0GB through 2GB Strongly-Ordered, 3G - 4G Normal Memory, Cachable Write-Back Write-Allocate, Non-Shareable and the last 1GB also Strongly-Ordered. Here is a brief execution steps it goes through: #1 Sets up the 2M-block at the 2nd level table with attributes. - sample block descriptor for translating from 0x8000_0000 virt to phys: 0x8000044d - bits[1:0] = 0b01 -> valid descriptor, descriptor type: block - bits[4:2] = 0b011 -> AttrIndx[2:0] points to MAIR0[3] . MAIR0[3] is 0xff - bits[5] = 0b0 - Non-secure - bits[7:6] = 0b01 - Access Permission: Read/write - bits[9:8] = 0b00 -> Shareability: non-shareable #2 Sets up 1st level table descriptor pointing to the descriptor shown above. It sets bits[1:0] to 0b11 meaning it is a table descriptor and valid. #3 Set control registers as follows HTCR is: 0x80000500 so - bits[9:8] = 0b01 -> Inner Cacheability to Normal memory, Outer Write-Back Write-Allocate Cacheable - bits[11:10] = 0b01 -> Outer Cacheability to Normal memory, Outer Write-Back Write-Allocate Cacheable - bits[13:12] = 0b00 -> Non-shareable HTTBR is: 0x00000000feff4000 -> points to 1st lavel table set in #2 HMAIR0 is: 0xffeeaa00 -> as shown above AttrIndx[2:0] points to MAIR0 and the four nibble being 0xff. 0xff is Normal memory, Inner Write-Back Cacheablea, Non-transientb HMAIR1 is: 0x00000000 - I set it to zero there as not used. #4 Finally it sets the M and C bits in HSCTLR registers Inspecting the page tables with amrds the region 3GB through 4GB that should be Normal and Cachable is Strongly-Ordered - 0x80000000 | L2 Block | NP:0x0000000080000000 | XN=0, PXN=0, Contiguous=0, nG=0, AF=1, SH=0x0, AP=0x1, AttrIndx=0x3 - H:0x80000000-0xFEFFFFFF | NP:0x80000000-0xFEFFFFFF | Strongly-ordered | NA | False | True | True Least not last are the parameters I pass to the model: FVP_Base_RevC-2xAEMvA --parameter bp.ve_sysregs.exit_on_shutdown=1 --parameter bp.virtio_net.enabled=1 --parameter bp.virtio_net.hostbridge.userNetworking=1 --parameter bp.virtio_net.hostbridge.userNetPorts=8022=22 --parameter cache_state_modelled=0 --parameter bp.secureflashloader.fname=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/bl1-fvp.bin --parameter bp.flashloader0.fname=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/fip-fvp.bin --parameter bp.virtioblockdevice.image_path=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/core-image-minimal-fvp-base-arm32-20250630100348.rootfs.wic --parameter cluster0.has_arm_v8-4=1 --parameter cluster1.has_arm_v8-4=1 --parameter cluster0.cpu0.CONFIG64=0 --parameter cluster0.cpu1.CONFIG64=0 --parameter cluster0.cpu2.CONFIG64=0 --parameter cluster0.cpu3.CONFIG64=0 --parameter cluster1.cpu0.CONFIG64=0 --parameter cluster1.cpu1.CONFIG64=0 --parameter cluster1.cpu2.CONFIG64=0 --parameter cluster1.cpu3.CONFIG64=0 --data cluster0.cpu0=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/zImage@0x80080000 --data cluster0.cpu0=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/fvp-base-revc.dtb@0x8fc00000 --parameter 'bp.terminal_0.terminal_command=tmux new-window -n "%title" "telnet localhost %port"' --parameter bp.terminal_1.start_telnet=0 --parameter bp.terminal_2.start_telnet=0 --parameter bp.terminal_3.start_telnet=0 --iris-server --iris-port 7102 --iris-allow-remote And an interrupted (not full for longevity) console log: NOTICE: Booting Trusted Firmware NOTICE: BL1: v2.8(debug):dd37aa5be-dirty NOTICE: BL1: Built : 20:04:50, Aug 4 2025 NOTICE: BL1: Booting BL2 NOTICE: BL2: v2.8(debug):dd37aa5be-dirty NOTICE: BL2: Built : 20:04:50, Aug 4 2025 NOTICE: BL1: Booting BL32 WARNING: FCONF: Invalid config id 26 INFO: SP_MIN FCONF: HW_CONFIG address = 0x7f00000 INFO: FCONF: Reading HW_CONFIG firmware configuration file from: 0x7f00000 INFO: FCONF: Reading firmware configuration information for: cpu_timer INFO: FCONF: Reading firmware configuration information for: uart_config INFO: FCONF: Reading firmware configuration information for: topology INFO: FCONF: Reading firmware configuration information for: gicv3_config NOTICE: SP_MIN: v2.8(debug):dd37aa5be-dirty NOTICE: SP_MIN: Built : 20:04:50, Aug 4 2025 U-Boot 2022.04 (Aug 06 2025 - 16:41:21 +0000) vexpress_aemv8a fvp aarch32 DRAM: 2 GiB WARNING: Caches not enabled Core: 2 devices, 2 uclasses Flash: 64 MiB MMC: Loading Environment from nowhere...

optee_ftpm + ms-tpm-20-ref support for RSA key sizes 3072 or 4096 causes a panic

by Dennis Kong

Dear community: I apologize in advance if this is the incorrect place to solicit for input on an issue I am having when enabling support of RSA key sizes > 2048. The environment is described below: TI AM642-EVM board Debian Bookworm running kernel 6.6.100, tpm_ftpm_tee.ko kernel module Uboot booting from sdcard UEFI partition and rootfs partition optee_os version 4.5.0 , 4.6.0, 4.7.0 (no difference in behaviour) optee_client version 4.5.0, 4.6.0, 4.7.0 (no difference in behaviour) optee_ftpm version 4.5.0 or 4.6.0, 4.7.0 (no difference in behaviour) ms-tpm-20-ref commit id 98b60a44aba79b15fcce1c0d1e46cf5918400f6a and e9fc7b89d865536c46deb63f9c7d0121a3ded49c Due to issues with RPMB, we decided to use REE_FS instead. Everything works correctly when I create RSA 2048 keys using tpm2-openssl and related tools: sudo tpm2_createprimary -C o -G rsa2048 -g sha256 -c primary.ctx, When I try rsa3072 or 4096, I get errors from the command line response saying invalid input parameters. I changed the ms-tpm-20-ref include file TpmProfile.h to set RSA_3072 and RSA_4096 macros both to (ALG_RSA && YES). After rebuilding and running, I now get an optee panic for ANY RSA key request INCLUDING rsa2048. I read suggestions to increase the MAX_COMMAND_SIZE/MAX_RESPONSE_SIZE on both the kernel driver tpm_ftpm_tee.ko and also optee_os/optee_ftpm, as well to increase relevant TA_STACK_SIZE and TA_HEAP_SIZE and TA_DATA_SIZE, but nothing seems to change the panic output: sudo tpm2_createprimary -C o -G rsa2048 -g sha256 -c primary.ctx============================================================ E/TC:? 0 E/TC:? 0 TA panicked with code 0xffff0007 E/LD: Status of TA bc50d971-d4c9-42c4-82cb-343fb7f37896 E/LD: arch: aarch64 E/LD: region 0: va 0x40005000 pa 0x9e8b0000 size 0x002000 flags rw-s (ldelf) E/LD: region 1: va 0x40007000 pa 0x9e8b2000 size 0x008000 flags r-xs (ldelf) E/LD: region 2: va 0x4000f000 pa 0x9e8ba000 size 0x001000 flags rw-s (ldelf) E/LD: region 3: va 0x40010000 pa 0x9e8bb000 size 0x004000 flags rw-s (ldelf) E/LD: region 4: va 0x40014000 pa 0x9e8bf000 size 0x001000 flags r--s E/LD: region 5: va 0x40015000 pa 0x9e934000 size 0x011000 flags rw-s (stack) E/LD: region 6: va 0x40026000 pa 0x8ebf0000 size 0x002000 flags rw-- (param) E/LD: region 7: va 0x4006e000 pa 0x9e8c0000 size 0x058000 flags r-xs [0] E/LD: region 8: va 0x400c6000 pa 0x9e918000 size 0x01c000 flags rw-s [0] E/LD: [0] bc50d971-d4c9-42c4-82cb-343fb7f37896 @ 0x4006e000 E/LD: Call stack: E/LD: 0x4006f394 E/LD: 0x40095edc E/LD: 0x4007b5a8 E/LD: 0x400985fc E/LD: 0x40098a70 E/LD: 0x4006fae0 E/LD: 0x400a5508 E/LD: 0x40098b9c D/TC:? 0 user_ta_enter:195 tee_user_ta_enter: TA panicked with code 0xffff0007 D/TC:? 0 release_ta_ctx:670 Releasing panicked TA ctx D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 [ 218.944680] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 [ 218.952379] tpm tpm0: tpm_try_transmit: send(): error -53212 D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 [ 218.963359] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 [ 218.974241] tpm tpm0: tpm_try_transmit: send(): error -53212 D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 [ 218.985675] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 [ 218.993366] tpm tpm0: tpm_try_transmit: send(): error -53212 [ 218.999044] tpm tpm0: tpm2_commit_space: error -14 ERROR:tcti:src/tss2-tcti/tcti-device.c:198:tcti_device_receive()D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 Failed to get response size fd 3, got errno 14: Bad address E[ 219.015351] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 RROR:esys:src/tss2-esys/api/Esys_CreatePrimary.c:404:Esys_Create[ 219.028348] tpm tpm0: tpm_try_transmit: send(): error -53212 Primary_Finish() Received a non-TPM Error ERROR:esys:src/tss2-esys/api/Esys_CreatePrimary.c:135:Esys_CreatePrimary() Esys Finish ErrorCode (0x000a000a) ERROR: Esys_CreatePrimary(0xA000A) - tcti:IO failure ERROR:esys:src/tss2-esys/esys_iutil.c:1145:iesys_check_sequence_async() Esys called in bad sequence. ERROR:esys:src/tss2-esys/api/Esys_FlushContext.c:66:Esys_FlushContext() Error in async function ErrorCode (0x00070007) ============================================================================= The last suggestion I saw was to change my dtb file to include a reserved memory region for optee shared memory and not use the default dynamic shared memory. The issue I have is kernel 6.6.100's tpm_ftpm_tee ignores the "memory-region" dts statement that references the optee_shm reserved memory at at 0xa4000000 in my case. Below is my snippet of the dts file. I heard there are patches in the kernel ftpm driver to support the reserved shared memory, but before I try the patches, can anyone opine whether this could cause the panic that I am seeing? Thanks in advance for anyone who can share any information optee_shm: optee-shm@a4000000 { compatible = "shared-dma-pool"; reg = <0x0 0xa4000000 0x0 0x01000000>; no-map; reusable; }; .... firmware { optee { compatible = "linaro,optee-tz"; method = "smc"; memory-region = <&optee_shm>; }; } Dennis Kong, P.Eng.

Does spmd_group0_interrupt_handler_nwd() need to take into account handling of special INTIDs?

by YANG Jun

Hi there, Do spmd_group0_interrupt_handler_nwd() and spmd_handle_group0_intr_swd() need to take into account handling of special INTIDs? Like ehf_el3_interrupt_handler(): /* * Acknowledge interrupt. Proceed with handling only for valid interrupt * IDs. This situation may arise because of Interrupt Management * Framework identifying an EL3 interrupt, but before it's been * acknowledged here, the interrupt was either deasserted, or there was * a higher-priority interrupt of another type. */ intr_raw = plat_ic_acknowledge_interrupt(); intr = plat_ic_get_interrupt_id(intr_raw); if (intr == INTR_ID_UNAVAILABLE) return 0; Best Regards, Joe Yang
