• Bit 10 in SBIOS ATPX function 1 is used to indicate whether Dynamic-zero is
supported on the platform. Setting it to 1 indicates that Dynamic-zero is
supported.
• On designs where BACO functionality is required, the SBIOS has to enable
PCIe® Gen1 that is required to support BACO mode, else the dGPU cannot
enter into BACO mode.
Please refer to
Switchable Graphics ACPI Control Methods, revision 0.26, for the
SBIOS ATPX function description on Intel platforms and AMD PowerXpress ACPI
Control Methods, revision 0.26A, for the SBIOS ATPX function description on AMD
platforms.
The details are described in SBIOS Requirements.
2.2.2 Extended Battery Mode
The extended battery mode provides a way to force an application rendering on the
fGPU/iGPU, bypassing GPU affinity as set in the application profile. It can be selected
by the following two options. A packaging option is used to choose one of the two
options.
1. An OEM application that calls ADL functions to set/reset extended battery
mode.
2.
User Power Plan selection for Plugged in and/or On battery as shown in the
following figure.
