Subject: [PATCH 0/6] Improve link speed presentation process
Date: Wed, 15 Jan 2020 17:04:17 +0800 [thread overview]
Message-ID: <1579079063-5668-1-git-send-email-yangyicong@hisilicon.com> (raw)
In this series:
1. Add 32 GT/s decoding in some macros as a complementary
2. Remove redundancy in speed presentation process and improve the codes.
Currently We use switch-case statements to acquire the speed
string according to the pci bus speed in current_link_speed_show()
and pcie_get_speed_cap(). It leads to redundant and when new
standard comes, we have to add cases in the related functions,
which is easy to omit at somewhere.
Abstract the judge statements out. Use macros and pci speed
arrays instead. Then only the macros and arrays need to be
extended when next generation comes.
