Hi Yuye, I sense those questions are related to downstream changes of yours, and I may not be able to provide accurate answers without seeing the code. Please clarify if the questions are related to the upstream version of Hafnium. See additional comments below [OD].

Before this, let me explain the background about the question. Now, I have run into host OS with Hafnium as spmc and OPTEE as SP. Then the optee driver will send a framwork message to Hafnium to inform it that whether the current state of the host OS is booting or running, [OD] What is a 'framework message' in this context? Is this a custom direct request from driver to optee? so that Hafnium could know which vm node(SP) it should load and init at current state. [OD] Can you please explain why this is required? This current state is represented by a global variable. [OD] do you mean a variable in Hafnium's BSS space? Will the global variable change when message flow exit Hafnium and enter it again? [OD] This depends in which section the variable is declared (see above). Regards, Yuye.

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.

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.

xtest 1034

by 梅建强(禹夜)

Hi, experts, For dynamic shared memory usage, I am not very clear. So we need to consult you about the related question. I failed to run xtest 1034 when I used Hafnium as SPMC and OPTEE as SP. Here are the debug logs： #./xtest 1034& [2] 10130 Test ID: 1034 Run test suite with level=0 TEE test application started over default TEE instance ###################################################### # # regression # ###################################################### regression_1034 Test loading a large TA WARNING: Atf_Debug(55): 0x8400006f 0x8001 0x0 0x80000000 0x0 0x0 0x0 0x0 VERBOSE: Hafnium_Debug ffa_handler func:0x8400006f D/TC:055 0 mobj_ffa_get_by_cookie:381 cookie 0 resurrecting D/TC:??? 0 tee_ta_init_pseudo_ta_session:296 Lookup pseudo TA 25497083-a58a-4fc5-8a72-1ad7b69b8562 D/TC:??? 0 ldelf_load_ldelf:96 ldelf load address 0x40008000 D/LD: ldelf:134 Loading TS 25497083-a58a-4fc5-8a72-1ad7b69b8562 F/TC:??? 0 trace_syscall:151 syscall Add constant time memcmp_ct function #3 <https://github.com/OP-TEE/optee_os/pull/3 > (syscall_get_property) F/TC:??? 0 trace_syscall:151 syscall GitHub usage documentation #5 <https://github.com/OP-TEE/optee_os/pull/5 > (syscall_open_ta_session) #D/TC:??? 0 ldelf_syscall_open_bin:143 Lookup user TA ELF 25497083-a58a-4fc5-8a72-1ad7b69b8562 (early TA) D/TC:??? 0 ldelf_syscall_open_bin:146 res=0xffff0008 D/TC:??? 0 ldelf_syscall_open_bin:143 Lookup user TA ELF 25497083-a58a-4fc5-8a72-1ad7b69b8562 (Secure Storage TA) VERBOSE: Hafnium_Debug ffa_handler func:0x84000070 WARNING: Atf_Debug(55): 0x84000070 0x80010000 0x0 0x0 0x1 0x0 0x0 0x0 WARNING: Atf_Debug(60): 0x84000073 0x50 0x50 0x0 0x0 0x0 0x0 0x0 VERBOSE: Hafnium_Debug ffa_handler func:0x84000073 VERBOSE: Marked sending complete.

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

That's useful to our project.We combined the Hafnium (run at S-EL2) and the optee (run at S-EL1), then modified the configuration to adapt to our own environment. Now we can start the os normally. Now we want to optimize a technical point, which is to load and run hafnium over 34G of free address space. This requires hafnium to support 64-bit load-address. I tried to modify the configuration in BUILD.gn as follows: origin_address = "0x880000000" And I encountered the build error: FAILED: secure_aem_v8a_fvp_clang/hafnium.elf ld.lld -pie --gc-sections --defsym=ORIGIN_ADDRESS=0x880000000 -O2 --icf=all --fatal-warnings --color-diagnostics -T /home/yuye/hafnium/Hafnium/build/image/image.ld -o secure_aem_v8a_fvp_clang/hafnium.elf --start-group @secure_aem_v8a_fvp_clang/hafnium.elf.rsp --end-group ld.lld: error: secure_aem_v8a_fvp_clang/obj/src/arch/aarch64/entry.entry.o:(.init.entry+0xC8): relocation R_AARCH64_ABS32 out of range: 36507222016 is not in [-2147483648, 4294967295]; references ORIGIN_ADDRESS >>> defined in -defsym:1 ninja: build stopped: subcommand failed.

hafnium page table configuration

by 梅建强(禹夜)

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. 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. 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… <https://git.trustedfirmware.org/hafnium/hafnium.git/commit/?id=dd883207ee9b… > Anyway, thanks for the support.
