Subject: [PATCH v2 0/3] perf hisi-ptt: Fix TLP header parsing and naming
Date: Thu, 30 Jul 2026 14:27:06 +0800	[thread overview]
Message-ID: <20260730062709.534139-1-liusizhe5@huawei.com> (raw)

This series fixes bugs and issues in the hisi_ptt packet decoder that were
introduced by commit 5e91e57e6809 ("perf auxtrace arm64: Add support
for parsing HiSilicon PCIe Trace packet").

Patch 1: Bugfix:
The DW0 bit-field layout of the hisi_ptt_4dw union does not match
the actual little-endian memory ordering, so the extracted
Format/Type/T9/T8/TH/SO/Length/Time fields are wrong.

Meanwhile, make all DW hex values printed in big-endian byte order
for readability.

Patch 2: Fix endianness / Heap out-of-bounds read / Integer truncation
issues.

Patch 3: Fix spelling / abbreviation errors in symbol names and macros.

---
Changes in v2:
- Move spelling error fixes to the end of the patch series.
- Add fixes tag only for bugfix.
- Use get_unaligned_le32() to make memory read more robust.
- Fix pre-existing issues reported by Sashiko in patch 2.
- Link to v1: https://lore.kernel.org/linux-pci/20260729060220.624250-1-liusizhe5@huawei.com/
