$ grep DMADEVICES /boot/config-6.3.0-0.rc2.20230315git6015b1aca1a2.25.fc39.x86_64+debug 
CONFIG_DMADEVICES=y
CONFIG_DMADEVICES_DEBUG=y
# CONFIG_DMADEVICES_VDEBUG is not set
$ grep DMADEVICES /boot/config-6.3.0-0.rc2.20230317git38e04b3e4240.27.fc39.x86_64+debug 
CONFIG_DMADEVICES=y
CONFIG_DMADEVICES_DEBUG=y
CONFIG_DMADEVICES_VDEBUG=y
