8.2.2 Clarify tee_host_tvm_initiate_fence #111

Open sqzsq opened 2 months ago

sqzsq commented 2 months ago

In the section "TVM-defined` shared memory regions", this ECALL sequence is defined:

  1. sbi_covh_tvm_invalidate_pages()
  2. tee_host_tvm_initiate_fence()
  3. sbi_covh_tvm_remove_pages()

This is the only instance of 'tee_host_tvm_initiate_fence' in the document.

Please clarify.

its a typo - it should refer to the sbi_covh_tvm_fence()

Similarly other typos:

tee_host_tsm_reclaim_pages --> sbi_covh_reclaim_pages tee_host_tvm_add_shared_pages --> sbi_covh_add_tvm_shared_pages sbi_tee_host_finalize_tvm --> sbi_covh_finalize_tvm
