Brief instructions to (re)compile nct6775 kernel module using DKMS

README.md

This gist helps in recompiling the NCT6775 kernel module

See https://bugzilla.kernel.org/show_bug.cgi?id=204807

I updated the gist for compiling on kernel >= 5.17 where the module's source was splitted in different files

dkms.conf

PACKAGE_NAME=nct6775
PACKAGE_VERSION=wim
BUILT_MODULE_NAME[0]="nct6775-core"
DEST_MODULE_LOCATION[0]="/kernel/drivers/hwmon"
BUILT_MODULE_NAME[1]="nct6775"
DEST_MODULE_LOCATION[1]="/kernel/drivers/hwmon"
AUTOINSTALL=yes
# currently no patch is shipped/applied
#PATCH[0]="nct6775-wim.patch"

Makefile

obj-m := nct6775-core.o
nct6775-objs                    := nct6775-platform.o
obj-$(CONFIG_SENSORS_NCT6775)   += nct6775.o
## this is not currently compiled
#obj-$(CONFIG_SENSORS_NCT6775_I2C) += nct6775-i2c.o

# tell DKMS where this source stuff it
sudo ln -s `realpath .` /usr/src/nct6775-wim

# compile files above
sudo dkms install nct6775/wim
