Subject: [PATCH 5/9] platform/x86: asus-wmi: store a min default for ppt options
Date: Mon, 25 Mar 2024 18:49:34 +1300 [thread overview]
Message-ID: <20240325054938.489732-6-luke@ljones.dev> (raw)
In-Reply-To: <20240325054938.489732-1-luke@ljones.dev>
Laptops with any of the ppt or nv tunables default to the minimum setting
on boot so we can safely assume a stored value is correct.
This patch adds storing of those values in the local struct, and enables
reading of those values back. To prevent creating a series of byte holes
in the struct the "<name>_available" bool is removed and
`asus_sysfs_is_visible()` uses the `ASUS_WMI_DEVID_<name>` directly.
