S_L4PE_02 Test Case "Check DC CVAP support" - Inquiry on Handling Strategy

[SilasCheng]

Hi ARM,

S_L4PE_02 requires persistent memory, but our hardware does not have persistent memory. As a result, the test case is SKIPPED during execution. Could you please advise on the recommended handling strategy? Thank you.

The execution log for this test case in UEFI is as follows:
START PE S_L4PE_02 28 : Check DC CVAP support
test_pool/pe/pe028.c:53 pe028_entry
Skipped at checkpoint - 2
END S_L4PE_02 SKIPPED

@SilasCheng,

S_L4PE_02 is conditional rule when system has persistent memory, in case your system does not have persistent memory the rule will not be applicable.

RS_L4PE_02 If the system contains persistent memory that is exposed to the OS, all PEs must support the clean to point of
persistence instruction (DC CVAP). The instruction must be able to perform a clean to the point of persistence
for all memory that is exposed as persistent memory to the OS.

Hi, @chetan-rathore
Sorry for the late reply. We were on holiday for the Spring Festival and just came back to work today. Our system currently does not have persistent memory, but this does not mean it does not support persistent memory. It's just that the current verification environment lacks persistent memory, which prevents this test case from being verified. If this test case cannot be verified, does it mean non-compliance with the ARM SBSA specification? Thanks.
