Then added yitian710 SoC DDR metrics and events alias. Change since v3: - Split the CMN and ali_drw patches. This patchset only contains ali_drw PMU related patches. The CMN metric related patches will be in another patchset. - Link: https://lore.kernel.org/all/1685438374-33287-1-git-send-email-renyu.zj@linux.alibaba.com/ $perf list: ... ali_drw: chi_rxdat [A packet at CHI RXDAT interface (write data).
