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.
