[redhat] New configs in drivers/platform
Hi,
As part of the ongoing rebase effort, the following configuration
options need to be reviewed.
As a reminder, the ARK configuration flow involves moving unreviewed
configuration options from the pending directory to the ark directory.
In the diff below, options are removed from the pending directory and
added to the ark hierarchy. The final options that need to be ACKed
are the files that are being added to the ark hierarchy.
If the value for a file that is added should be changed, please reply
with a better option.
CONFIG_SURFACE_HOTPLUG:
Driver for out-of-band hot-plug event signaling on Microsoft Surface
devices with hot-pluggable PCIe cards.
This driver is used on Surface Book (2 and 3) devices with a
hot-pluggable discrete GPU (dGPU). When not in use, the dGPU on those
devices can enter D3cold, which prevents in-band (standard) PCIe
hot-plug signaling. Thus, without this driver, detaching the base
containing the dGPU will not correctly update the state of the
corresponding PCIe device if it is in D3cold. This driver adds support
for out-of-band hot-plug notifications, ensuring that the device state
is properly updated even when the device in question is in D3cold.
Select M or Y here, if you want to (fully) support hot-plugging of
dGPU devices on the Surface Book 2 and/or 3 during D3cold.
Symbol: SURFACE_HOTPLUG [=n]
Type : tristate
Defined at drivers/platform/surface/Kconfig:89
Prompt: Surface Hot-Plug Driver
Depends on: SURFACE_PLATFORMS [=y] && GPIOLIB [=y]
Location:
-> Device Drivers
-> Microsoft Surface Platform-Specific Device Drivers (SURFACE_PLATFORMS [=y])
---
CONFIG_X86_PLATFORM_DRIVERS_DELL:
Say Y here to get to see options for device drivers for various
Dell x86 platforms, including vendor-specific laptop extension drivers.
This option alone does not add any kernel code.
If you say N, all options in this submenu will be skipped and disabled.
Symbol: X86_PLATFORM_DRIVERS_DELL [=n]
Type : bool
Defined at drivers/platform/x86/dell/Kconfig:6
Prompt: Dell X86 Platform Specific Device Drivers
Depends on: X86 [=y] && X86_PLATFORM_DEVICES [=y]
Location:
-> Device Drivers
-> X86 Platform Specific Device Drivers (X86_PLATFORM_DEVICES [=y])
