February 2023 - Hafnium - lists.trustedfirmware.org

by Jens Wiklander

Hi, I'm testing with Hafnium as SPMC at S-EL2 and OP-TEE as an SP at S-EL1 on QEMU v7.0.0. I've run into a few problems and fixed most of them. I believe the setup is similar to what Shiju is using in this mail thread https://lists.trustedfirmware.org/archives/list/hafnium@lists.trustedfirmwa… My setup can be duplicated with: repo init -u https://github.com/jenswi-linaro/manifest.git -m qemu_v8.xml \ -b qemu_sel2 repo sync -j8 (cd hafnium && git submodule init && git submodule update) cd build make -j8 toolchains make -j8 all make run-only With this xtest -x 1034 passes, xtest 1034 often causes ERROR: Data abort: pc=0xe1198b8, esr=0x96000006, ec=0x25, far=0x9c Panic: EL2 exception Xtest runs dreadfully slow, I haven't investigated why yet, but at least it works. This is based on patches provided by Olivier at: [1] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16412/2 [2] https://review.trustedfirmware.org/c/hafnium/hafnium/+/16323/7 I've also encountered the problem cache maintenance problem Shiju described in the mail thread above: NOTICE: Trapped access to system register write: op0=1, op1=0, crn=7, crm=14, op2=2, rt=11. It can be worked around by compiling OP-TEE with CFG_CORE_WORKAROUND_NSITR_CACHE_PRIME=n. I'm pretty sure we do dcache clean+inv elsewhere so I'm surprised it fails here. Is Hafnium expected to block dcache clean+inv? For Hafnium I've added two patches on top of [2], available at https://github.com/jenswi-linaro/hafnium/tree/qemu_sel2: - 79b4d2cbe06e SPMC: add missing ME initialization for secondary cores - 659c79d5eacf feat(mm): fix FEAT_LPA workaround For TF-A I've added a few patches on top of [1], available at https://github.com/jenswi-linaro/arm-trusted-firmware/tree/qemu_sel2: - a040396cae9e feat(qemu): add tos-fw-config for sel2 spmc - 4f7d91723485 fix(qemu): change TOS_FW_CONFIG_NAME value - fbfc9a222c7f spmd_smc_handler() add s/ns state to SMC traces - ca65081b9cdc feat(sptool): add dependency to SP image - b1e1b46a0680 fix(qemu): restore code to added needed psci nodes For OP-TEE I've also added a few patches, available at https://github.com/jenswi-linaro/optee_os/tree/qemu_sel2: - 1057def23777 plat-vexpress: sel2 spmc: update for hafnium - f18a54ed3524 core: ffa: use hvc instead of smc with S-EL2 - d18bbc92f7c1 core: mobj_ffa_add_pages_at() trust addresses from SPMC There's also one patch for QEMU on top of v7.0.0, available at: https://github.com/jenswi-linaro/qemu/tree/qemu_sel2 - 0c1e39672dcb Read PS bits from VTCR_EL2 The QEMU problem is fixed in v.7.1.0, but I can't get that version of QEMU to work with TF-A. I guess it's because of yet another new CPU feature since I'm running with "-cpu max". I'll try to upstream the Hafnium and TF-A patches that make sense on their own. What's the plan with the interrupt controller? How will OP-TEE be able to handle secure interrupts? The hafnium git pulls in a few git submodules and even the source code for a Linux kernel. I guess this is useful in your internal CI setup, but when used isolated as in my setup it makes no sense at all. It would also be nice to be able to build with an external toolchain. I hope this is a temporary situation, I don't see why Hafnium should be pickier about toolchain than for instance TF-A. Speaking of building, I haven't been able to figure out how to build only for the QEMU variant I need so right now I'm building for everything and that takes a bit longer than necessary. I'm going to maintain the setup above as long as it's relevant to me. I may add more patches on the branches or even rebase as needed. So if anyone is using this, keep in mind that my branches may change without warning. Thanks, Jens

splitting NS/S IPA spaces

by Olivier Deprez

Hi Jens, I have a couple of Hafnium changes implementing the use of VSTTBR_EL2/VTTBR_EL2 to split an SP IPA into secure and non-secure IPA spaces. They're very much in experimental stage so difficult to share just now (I will do some time later in February). However I'd like to report some possible issue observed with qemu. Essentially, when normal world driver inits, it performs a first share operation for a single NS page: INFO: 1> 1 0 FFA_MEM_SHARE_32(84000073) 50 50 0 0 0 0 0 [...] VERBOSE: Marked sending complete.

So it seems qemu is not doing the translation properly from VTTBR_EL2 for a page mapped NS by OP-TEE (hence NS IPA space). Who should I report this problem to? Regards, Olivier.

Removing support for HF_DEBUG_LOG

by Kathleen Capella

Hi, With the introduction of FFA_CONSOLE_LOG ABI [1], we are intending to replace and remove support for HF_DEBUG_LOG. This proposal is in review in the following stages: 1) Remove the dependency of hftest VMs on HF_DEBUG_LOG and move to FFA_CONSOLE_LOG [2] 2) Remove the support for HF_DEBUG_LOG (i.e. api_debug_log) from hafnium project. [3] The adoption of FFA_CONSOLE_LOG will allow us to make use of its ability to log multiple characters at a time, as opposed to HF_DEBUG_LOG which writes one character at a time. This improvement will be enabled in a future patch. Also, should [3] be adopted, we will make accompanying changes to tf-a-tests Cactus-based tests. We want to know if there are any concerns about removing support for HF_DEBUG_LOG at this time as we realize other downstream SPs may rely on its support. Thank you, Kathleen Capella [1] feat(console_log): add FFA_CONSOLE_LOG ABI https://review.trustedfirmware.org/c/hafnium/hafnium/+/15334 [2] feat(ffa_console_log): replace hf_debug_log https://review.trustedfirmware.org/c/hafnium/hafnium/+/19513 [3] refactor: remove support for HF_DEBUG_LOG https://review.trustedfirmware.org/c/hafnium/hafnium/+/19681

deprecating non vhe builds

by Olivier Deprez

Hi, Current Hafnium build and test configs cover both cases of non-VHE (HCR_EL2.E2H=0) and VHE (HCR_EL2.E2H=1). From an Arm architecture perspective the latter is a superset of the former. We get to know that non-VHE becomes a legacy, and other projects in general tend to always enable Armv8.1 VHE extension early at boot. Our focus being S-EL2 (Armv8.4+) it looks reasonable to assume Armv8.1's VHE is present on chipsets loading and booting Hafnium. That said we're exploring the possibility to abandon 'non-vhe' builds, and focus build and test on vhe-enabled builds. The intent to simplify build configurations, and improve build and test time. Joao made experiments in 2 steps, first on removing the said build configurations, and then runtime checks. This gives good results at least in terms of build time , and simplification in build/test scripts. https://review.trustedfirmware.org/c/hafnium/hafnium/+/18925/ https://review.trustedfirmware.org/c/hafnium/project/reference/+/18926/ This message is to poll the community for feedback, as to whether this is foreseen as an issue (or not!) for on going deployments, before we engage further in this refactoring. Thanks & Regards, Olivier.

Re: hafnium page table configuration

by Olivier Deprez

Hi Yuye, See comments inline [OD]. Regards, Olivier. ________________________________ From: 梅建强(禹夜) <meijianqiang.mjq(a)alibaba-inc.com> Sent: 22 February 2023 04:17 To: Olivier Deprez <Olivier.Deprez(a)arm.com>; hafnium <hafnium(a)lists.trustedfirmware.org> Cc: 高海源(码源) <haiyuan.ghy(a)alibaba-inc.com>; 王一蒙(北见) <wym389994(a)alibaba-inc.com> Subject: 回复：[Hafnium] hafnium page table configuration Hi, Olivier, Sorry for the delay in replying to this query. As I've seen in the documentation, in the case of hafnium implemented as S-EL2, NWd uses shared memory to communicate with SWd and there are two steps to register the page table. Please correct me if there are any errors in my description. Firstly, Linux sends FFA_MEM_SHARE to SPMC (Hafnium), which completes memory mapping for S-EL1's stage-2 transition. Secondly, Linux sends FFA_MSG_SEND_DIRECT_REQ to OPTEE, and OPTEE then retrieves the IPA space from SPMC according to the cookie received and then completes the memory mapping for S-EL1's stage-1 transition. [OD] That's quite correct, with the subtle difference that the region is mapped in SP's S2 page tables upon the receiver SP emitting the memory retrieve request. The SP maps the region in the S1 page tables after receiving the memory retrieve response from the SPMC. Our solution to the problem is: After the first step be completed, we add the invalidation of TLB, which seems to greatly reduce the probability of problem occurrence when testing the optee_examples. The root cause still needs to be further located. [OD] There is a probable miss with invalidating the S2 TLB entries for NS IPA space. Interestingly, this issue is not observed with models, but likely to happen on real silicon. Can you try the suggested temp. fix from https://github.com/OP-TEE/optee_os/issues/5803#issuecomment-1436084763 ? (while reverting your own TLB invalidation fix. ?) I'm working on a cleaner fix, and prioritize if this issue is confirmed at your end. It should be noted that our OPTEE version is based on 3.19-rc, and Hafnium version is based on the commit: https://git.trustedfirmware.org/hafnium/hafnium.git/commit/?id=dd883207ee9b… Anyway, thanks for the support.

We solved the problem by update our Hafnium codebase on rebase of commit ca03054ba6a351534b93e6d64c12e671578eb340. The origin Hafnium codebase is on rebase of commit dd883207ee9b31c19169adf97c918d561dcb9a5c. OPTEE codebase stays with version 3.20.0. Which commit can solve this problem is still under investigation. I guess the reason may relate to that Hafnium has updated the implementation of FF-A mechanism in new commit. If you have already known the reason, please tell me. 2. In addition, although some cases run successfully, there are still many error messages generated during their running process, such as the following cases: * regression_1034 Test loading a large TA E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x1 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x3 E/TC:??? 0 mobj_ffa_get_by_cookie:423 Failed to get cookie 0x3 internal_offs 0 E/LD: init_elf:486 sys_open_ta_bin(25497083-a58a-4fc5-8a72-1ad7b69b8562) E/TC:??? 0 ldelf_init_with_ldelf:131 ldelf failed with res: 0xffff000c TEEC_ERROR_OUT_OF_MEMORY - ignored regression_1034 OK * regression_1022 Test dlopen()/dlsym()/dlclose() API E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x1 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x3 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x3 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x1 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x3 E/TC:??? 0 E/TC:??? 0 TA panicked with code 0x0 E/LD: Status of TA 5b9e0e40-2636-11e1-ad9e-0002a5d5c51b E/LD: arch: aarch64 E/LD: region 0: va 0x40006000 pa 0xf0404000 size 0x002000 flags rw-s (ldelf) E/LD: region 1: va 0x40008000 pa 0xf0406000 size 0x011000 flags r-xs (ldelf) E/LD: region 2: va 0x40019000 pa 0xf0417000 size 0x001000 flags rw-s (ldelf) E/LD: region 3: va 0x4001a000 pa 0xf0418000 size 0x004000 flags rw-s (ldelf) E/LD: region 4: va 0x4001e000 pa 0xf041c000 size 0x001000 flags r--s E/LD: region 5: va 0x4001f000 pa 0xf052e000 size 0x003000 flags rw-s (stack) E/LD: region 6: va 0x40038000 pa 0x00000000 size 0x00f000 flags r-xs [2] E/LD: region 7: va 0x40047000 pa 0x0000e000 size 0x002000 flags rw-s [2] E/LD: region 8: va 0x40054000 pa 0x00000000 size 0x00f000 flags r-xs [1] E/LD: region 9: va 0x40063000 pa 0x0000e000 size 0x002000 flags rw-s [1] E/LD: region 10: va 0x4008b000 pa 0x00001000 size 0x02a000 flags r-xs [0] E/LD: region 11: va 0x400b5000 pa 0x0002b000 size 0x0e7000 flags rw-s [0] E/LD: [0] 5b9e0e40-2636-11e1-ad9e-0002a5d5c51b @ 0x4008b000 E/LD: [1] ffd2bded-ab7d-4988-95ee-e4962fff7154 @ 0x40054000 E/LD: [2] b3091a65-9751-4784-abf7-0298a7cc35ba @ 0x40038000 E/LD: Call stack: E/LD: 0x4009e5a8 E/LD: 0x400a09b8 E/LD: 0x4009ed0c regression_1022 OK The E/TC message generated by mobj_ffa_get_by_cookie appears in almost all cases. Is this related to FFA_MEM_FRAG_RX/TX, or something else? And what is related to the E/LD message? I am currently studying the FFA specification to try to explain these problems. And some related questions raised in the other email(subject: Hafnium Dynamic Shared Memory). You can tell me if it's convenient for you. 3. Could memory managed by Hafnium be configured in any other way except by spmc manifest? Does Hafnium support the configuration of the location of running memory such as text, data, stacks, and heap? If yes, how? Thanks you for your help.

Re: xtest 1034

by 梅建强(禹夜)

Hi, Olivier, 1. We solved the problem by update our Hafnium codebase on rebase of commit ca03054ba6a351534b93e6d64c12e671578eb340. The origin Hafnium codebase is on rebase of commit dd883207ee9b31c19169adf97c918d561dcb9a5c. OPTEE codebase stays with version 3.20.0. Which commit can solve this problem is still under investigation. I guess the reason may relate to that Hafnium has updated the implementation of FF-A mechanism in new commit. If you have already known the reason, please tell me. 2. In addition, although some cases run successfully, there are still many error messages generated during their running process, such as the following cases: * regression_1034 Test loading a large TA E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x1 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x3 E/TC:??? 0 mobj_ffa_get_by_cookie:423 Failed to get cookie 0x3 internal_offs 0 E/LD: init_elf:486 sys_open_ta_bin(25497083-a58a-4fc5-8a72-1ad7b69b8562) E/TC:??? 0 ldelf_init_with_ldelf:131 ldelf failed with res: 0xffff000c TEEC_ERROR_OUT_OF_MEMORY - ignored regression_1034 OK * regression_1022 Test dlopen()/dlsym()/dlclose() API E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x1 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x3 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x3 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x1 E/TC:011 0 mobj_ffa_get_by_cookie:384 Populating mobj from rx buffer, cookie 0x3 E/TC:??? 0 E/TC:??? 0 TA panicked with code 0x0 E/LD: Status of TA 5b9e0e40-2636-11e1-ad9e-0002a5d5c51b E/LD: arch: aarch64 E/LD: region 0: va 0x40006000 pa 0xf0404000 size 0x002000 flags rw-s (ldelf) E/LD: region 1: va 0x40008000 pa 0xf0406000 size 0x011000 flags r-xs (ldelf) E/LD: region 2: va 0x40019000 pa 0xf0417000 size 0x001000 flags rw-s (ldelf) E/LD: region 3: va 0x4001a000 pa 0xf0418000 size 0x004000 flags rw-s (ldelf) E/LD: region 4: va 0x4001e000 pa 0xf041c000 size 0x001000 flags r--s E/LD: region 5: va 0x4001f000 pa 0xf052e000 size 0x003000 flags rw-s (stack) E/LD: region 6: va 0x40038000 pa 0x00000000 size 0x00f000 flags r-xs [2] E/LD: region 7: va 0x40047000 pa 0x0000e000 size 0x002000 flags rw-s [2] E/LD: region 8: va 0x40054000 pa 0x00000000 size 0x00f000 flags r-xs [1] E/LD: region 9: va 0x40063000 pa 0x0000e000 size 0x002000 flags rw-s [1] E/LD: region 10: va 0x4008b000 pa 0x00001000 size 0x02a000 flags r-xs [0] E/LD: region 11: va 0x400b5000 pa 0x0002b000 size 0x0e7000 flags rw-s [0] E/LD: [0] 5b9e0e40-2636-11e1-ad9e-0002a5d5c51b @ 0x4008b000 E/LD: [1] ffd2bded-ab7d-4988-95ee-e4962fff7154 @ 0x40054000 E/LD: [2] b3091a65-9751-4784-abf7-0298a7cc35ba @ 0x40038000 E/LD: Call stack: E/LD: 0x4009e5a8 E/LD: 0x400a09b8 E/LD: 0x4009ed0c regression_1022 OK The E/TC message generated by mobj_ffa_get_by_cookie appears in almost all cases. Is this related to FFA_MEM_FRAG_RX/TX, or something else? And what is related to the E/LD message? I am currently studying the FFA specification to try to explain these problems. And some related questions raised in the other email(subject: Hafnium Dynamic Shared Memory). You can tell me if it's convenient for you. 3. Could memory managed by Hafnium be configured in any other way except by spmc manifest? Does Hafnium support the configuration of the location of running memory such as text, data, stacks, and heap? If yes, how? Thanks you for your help.

Can someone help me see what the problem is? Regards, Yuye.

Hafnium Dynamic Shared Memory

by 梅建强(禹夜)

Hi, experts Here are the comments I saw in the Hafnium code. /* * Hafnium doesn't support fragmentation of memory retrieve requests * (because it doesn't support caller-specified mappings, so a request * will never be larger than a single page), so this must be part of a * memory send (i.e. donate, lend or share) request. * * We can tell from the handle whether the memory transaction is for the * TEE or not. */ I have a few questions about this description. 1. In the case of Hafnium as SPMC, optee should register memory fragments allocated by linux. What does Hafnium do with these memory fragments since doesn't support fragmentation of memory retrieve requests? 2. How does Hafnium map the page tables of stage-2 in dynamic shared memory for CA/TA, and are these page tables stored in the heap, or where? 3. What does HF_MAILBOX for dynamic shared memory mean? How does it relate to RX/TX buffer? Where can I see the related introduction in detail? Regards, Yuye
