I am a little confused.
CONFIG_DRM_KMS_FB_HELPER
I have this in my 'make menuconfig'
│ Symbol: DRM_KMS_FB_HELPER [=n]
│
│ Type : bool
│
│ Defined at drivers/gpu/drm/Kconfig:75
│
│ Depends on: HAS_IOMEM [=y] && DRM_KMS_HELPER [=m]
I checked every option under 'drivers/gpu/drm/'
I don't see one option with description of 'CONFIG_DRM_KMS_FB_HELPER'. Is this
normal?
I only have, under "Device Drivers > Graphics support > Direct Rendering
Manager (XFree86 4.1.0 and higher DRI support)":
--- Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)
│ │
│ │ [ ] DRM DP AUX
Interface
│ │
│ │ [ ] Insert extra
checks and debug info into the DRM range managers
│ │
│ │ < > kselftests for
DRM
│ │
│ │ [ ] Enable legacy
fbdev support for your modesetting driver
│ │
│ │ [*] Allow to
specify an EDID data set instead of probing for it.
I supposed I can just add CONFIG_DRM_KMS_FB_HELPER=y line to .config and
compile it this way, but why is it disabled and not in config file by default?
Is it even significant?
