80860f14 | Acpi

In the kernel source code ( drivers/acpi/acpi_lpss.c ), Intel LPSS devices are defined with specific IDs. The 80860F14 entry enables the dw_i2c driver (DesignWare I2C).

note that while functional, it results in slower application load times compared to standard SATA or NVMe drives. Acpi 80860f14

The 80860F14 entry tells the OS: "There is an SST Audio DSP here, and it is connected to a codec at I2C address 0x1A." However, the ACPI tables often fail to properly provide: In the kernel source code ( drivers/acpi/acpi_lpss

If you own any of these devices and run Linux, ACPI 80860F14 is likely the sole barrier to functional onboard audio. The 80860F14 entry tells the OS: "There is

: On Linux distributions, this device frequently causes headaches. Common issues include the card reader failing to "wake up" after suspend or failing to detect cards entirely. In some cases, developers have had to create custom patches to bypass "dependency checking" in the Linux kernel to get the SDHCI-ACPI driver to initialize correctly. Hardware Limitations

Put together, ACPI 80860F14 points directly to an Intel internal peripheral. According to Intel’s documentation and Linux kernel mailing lists, corresponds to the Intel SST (Smart Sound Technology) Audio DSP – specifically the Low Power Engine (LPE) audio controller found on Bay Trail-T and Bay Trail-CR platforms.
