Subject: [PATCH 07/10] perf hisi-ptt: Merge 4DW and 8DW HEAD0 printing
Date: Thu, 4 Jun 2026 15:50:02 +0800 [thread overview]
Message-ID: <20260604075005.2219785-8-liusizhe5@huawei.com> (raw)
In-Reply-To: <20260604075005.2219785-1-liusizhe5@huawei.com>
Merge the printing of HEAD0 for both 4DW and 8DW TLP headers into
hisi_ptt_print_head0(). This unifies the entry point and makes it
easier to add HEAD1/HEAD2/HEAD3 field parsing in subsequent patches.
