About the SDS usage model

by Deng Bob

Hi all, I am trying to raise a question about SDS. As you know, SDS (Shared data storage) is used to communicate or exhcange info among different processor units like AP, SCP, RSE, etc. So, do we need to add some lock mechanisms to protect the data when one processor entity is accessing it? After I reviewed the open source Trusted Firmware and SCP firmware it looks to me that both Trusted Firmware and SCP directly access the shared memory region without any limitation. Currently, it just uses the 'valid' flag to identify if the data is ready to use, is this good enough? Looking forwared to your response! Thank you!!! Best Regards, Bob

TF-A EL3 SPMC upgrade to FF-A Spec v1.2

by Belsare, Akshay

Hi Marc, In TF-A, the FF-A version is currently set to v1.2, but I am unable to find the corresponding implementation for EL3 SPMC configuration. I'm particularly interested in the support for FF-A Notification Mechanism. Could you please provide the timeline for when this will be added to the TF-A EL3 SPMC configuration? Thank You!

PSA calls with RSE comms and MHU

by Yann Gautier

Hello, I would like to use PSA calls for an application on STM32MP2 platform. I've seen the psa_call() API that I could use, in drivers/arm/rse/rse_comms.c. The problem is that it is based on MHU mailbox, which I don't have on STM32MP2. So I was planning plan to disentangle RSE comms and MHU, having a new file in the same directory to manage MHU. This code should then be under a flag, I could re-use PLAT_MHU_VERSION. Setting it to 0, would mean no MHU. AFAICT TF-M uses that split with a dedicated file: rse_comms_hal.c: Abstracts MHU message sending and receiving. (see https://tf-m-user-guide.trustedfirmware.org/platform/arm/rse/rse_comms.html). Do you think this approach sounds right? Thanks, Yann

How to map a physical address using `mmap_add_dynamic_region_alloc_va`?

by 钱非凡

Hi experts, I tried to allocate a physical memory address in Linux Kernel, and pass the memory address to tf-a using smc call. As I asked in previous mails (https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.…), tf-a can not access the physical memory address directly, so I try to use the `mmap_add_dynamic_region_alloc_va` function in `xlat_table_v2` Library, and map the physical memory in tf-a. After calling the function, It does return a new virtual memory address, but I still failed to access the address, is there any details I have missed? Here is the code: ``` NOTICE("phys_addr: 0x%lx, virt_addr: 0x%lx\n", phys_addr, virt_addr); int rc = mmap_add_dynamic_region_alloc_va(phys_addr, ptr_virt_addr, size, MT_NS | MT_RW_DATA); if (rc) { WARN("Failed to map memory at 0x%lx: %d\n", phys_addr, rc); return; } NOTICE("virt_addr_el3: 0x%lx\n", virt_addr_el3); NOTICE("virt_addr_el3[0] = 0x%x\n", *((uint32_t *)virt_addr_el3)); ``` Here is the output: ``` NOTICE: phys_addr: 0x40f0000, virt_addr: 0xffff0000040f0000 NOTICE: mm.base_va: 0 NOTICE: mm.base_va: 100000000 NOTICE: virt_addr_el3: 0x100000000 [ 38.540464] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks: [ 38.546584] rcu: 4-...0: (1 ticks this GP) idle=4224/1/0x4000000000000000 softirq=125/125 fqs=2625 [ 38.555651] (detected by 0, t=5252 jiffies, g=-779, q=16 ncpus=8) [ 38.561843] Task dump for CPU 4: [ 38.565075] task:main state:R running task stack:0 pid:195 ppid:181 flags:0x00000002 [ 38.575015] Call trace: [ 38.577464] __switch_to+0xe4/0x160 [ 38.580975] 0x42 ``` I would be grateful for any advice or suggestions you may have.

Query regarding the test coverage thru tf-a-tests

by Thangaraj, Senthil Nathan

Dear TF-A team, I have a query regarding the TF-A test. Specifically, I would like to know if there is a method to find out the code coverage for a specific test or for all the tests in current run? Your direction in this regard will be really appreciated. Thank you, Senthil

Arm TF-A can not access linux kernel's virtual/physical address?

by 钱非凡

In my opinion, Arm TF-A (EL3) has higher privileges than Linux Kernel (EL1), and Secure World should be able to access all memory address in Normal World. To verify this feature, I added a new SMC call in Arm TF-A and wrote a kernel module to test it (on a Hikey960 Development Board). But the program does not run as expected that Arm TF-A stucked while accessing the memory address passed by Linux Kernel. Here is my kernel module, which uses `alloc_pages` to acquire a physical address, and uses `page_address` converting it to a virtual address. And the module passes the physical address and the virtual address to Arm TF-A using `smc #0`: ```cpp static int __init smc_testing_init(void) { uintptr_t phys_addr, virt_addr; pr_info("Mmodule loaded\n"); phys_addr = (uintptr_t) alloc_pages(GFP_KERNEL, 2); virt_addr = (uintptr_t) page_address((struct page *) phys_addr); memset((void *) virt_addr, 'A', PAGE_SIZE << 2); printk("phys_addr: 0x%llx, virt_addr: 0x%llx\n", (uint64_t) phys_addr, (uint64_t) virt_addr); asm volatile( "ldr x0, =0xC8000003\n" "mov x1, %0\n" "mov x2, %1\n" "smc #0\n" : : "r" (phys_addr), "r" (virt_addr) : "x0", "x1", "x2" ); __free_pages((struct page *) phys_addr, 2); return 0; } static void __exit smc_testing_exit(void) { pr_info("Module unloaded\n"); } ``` And here is the handler's code in Arm TF-A, which prints the addresses of physical address and virtual address, and access the first element of the memory address: ```cpp if (0xC8000003 == smc_fid) { uintptr_t virt_addr = x3; NOTICE("phys_addr: 0x%lx, virt_addr: 0x%lx\n", phys_addr, virt_addr); NOTICE("virt_addr[0] = 0x%x\n", *((uint32_t *)virt_addr)); NOTICE("phys_addr[0] = 0x%x\n", *((uint32_t *)phys_addr)); SMC_RET0(handle); } ``` Here is the output, Arm TF-A handles the request successfully, but failed to access the memory address passed by Linux Kernel: ```bash # insmod ./smc_testing.ko [ 75.259590] smc_testing: loading out-of-tree module taints kernel.
