Subject[PATCH v6 00/21] perf arm-spe: Refactor decoding & dumping flow
Date
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);
