This is patch set v6 for refactoring Arm SPE trace decoding and dumping. It follows Andre's comment to directly bail out arm_spe_pkt_snprintf() if any error occurred.
This patch set is cleanly applied on the top of perf/core branch with commit 7cf726a59435 ("Merge tag 'linux-kselftest-kunit-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest").
Have tested this patch set on Hisilicon D06 platform with commands "perf report -D" and "perf script", compared the decoding results between with this patch set and without this patch set, didn't find issue with "diff" tool.
Changes from v5: - Directly bail out arm_spe_pkt_snprintf() if any error occurred (Andre).
Changes from v4: - Implemented a cumulative error for arm_spe_pkt_snprintf() and changed to condense code for printing strings (Dave); - Changed to check payload bits [55:52] for parse kernel address (Andre).
Changes from v3: - Refined arm_spe_payload_len() and removed macro SPE_HEADER_SZ() (Andre); - Refined packet header index macros (Andre); - Added patch "perf arm_spe: Fixup top byte for data virtual address" to fixup the data virtual address for 64KB pages and refined comments for the fixup (Andre); - Added Andre's review tag (using "b4 am" command); - Changed the macros to SPE_PKT_IS_XXX() format to check operation types (Andre);
