Hello, I want to read a memory(kmalloc in kernel) in EL3, and I have get the PA of memory. But I can't read it. Why? Thanks.
Thanks.I have found this problem. I don't map the PA into EL3 VA space. Now I try to map the PA and fail to do it by function(mmap_add_dynamic_region_alloc_va and mmap_add_region_alloc_va), please tell me the way to mapp the PA into EL3 VA space. Thanks. Ignore my poor English.
