Subject: [PATCH 05/10] perf hisi-ptt: Complete the field names for 4DW and 8DW packets
Date: Thu, 4 Jun 2026 15:50:00 +0800	[thread overview]
Message-ID: <20260604075005.2219785-6-liusizhe5@huawei.com> (raw)
In-Reply-To: <20260604075005.2219785-1-liusizhe5@huawei.com>

Add the missing HISI_PTT_4DW_HEAD0 entry to the 4DW field name table
and add the HISI_PTT_8DW_CHK_AND_RSV0/HISI_PTT_8DW_RSV1 entries to
the 8DW field name table so that all DW indices have corresponding
names.
Replace the variable in the printing loop with enum members.

8DW format is like:
bits [                 31:11                 ][       10:0       ]
     |---------------------------------------|-------------------|
 DW0 [                0x1fffff               ][ Reserved (0x7ff) ]
 DW1 [                       Prefix                              ]
 DW2 [                     Header DW0                            ]
 DW3 [                     Header DW1                            ]
 DW4 [                     Header DW2                            ]
 DW5 [                     Header DW3                            ]
 DW6 [                   Reserved (0x0)                          ]
 DW7 [                        Time                               ]
