Subject: [PATCH 6/7] drm/amd/pm: integrate plpd allow/disallow into select_xgmi_plpd_policy in ppt level
Date: Mon, 25 Sep 2023 12:27:51 +0800	[thread overview]
Message-ID: <20230925042752.3847-6-le.ma@amd.com> (raw)
In-Reply-To: <20230925042752.3847-1-le.ma@amd.com>

The allow_xgmi_power_down(true/false) will be generally replaced by:
  - allow: select_xgmi_plpd_policy(XGMI_PLPD_DEFAULT)
  - disallow: select_xgmi_plpd_policy(XGMI_PLPD_DISALLOW)
