Subject: Re: [PATCH v5 0/8] Support Multi-frequency scale for UFS
Date: Thu, 20 Feb 2025 22:13:35 -0500 [thread overview]
Message-ID: <yq134g8j8h7.fsf@ca-mkp.ca.oracle.com> (raw)
In-Reply-To: <20250213080008.2984807-1-quic_ziqichen@quicinc.com> (Ziqi Chen's message of "Thu, 13 Feb 2025 16:00:00 +0800")
Ziqi,
> With OPP V2 enabled, devfreq can scale clocks amongst multiple
> frequency plans. However, the gear speed is only toggled between min
> and max during clock scaling. Enable multi-level gear scaling by
> mapping clock frequencies to gear speeds, so that when devfreq scales
> clock frequencies we can put the UFS link at the appropraite gear
> speeds accordingly.
Applied to 6.15/scsi-staging, thanks!
