It can either be an absolute or a 5# relative path. If it is a relative path, then it must be relative to the 6# kernel source directory (KERNEL_SRC). An absolute path can be obtained very 7# easily through $(shell pwd). Generating a path relative to KERNEL_SRC is 8# difficult and we accept some outside help by letting the caller override the 9# variable $(M). Allowing a relative path for $(M) enables us to have the build 10# system put output/object files (.o, .ko.) into a directory different from the 11# module source directory. 12M ?= $(shell pwd) 13 14ifeq ($(WLAN_ROOT),) 15# WLAN_ROOT must contain an absolute path (i.e. not a relative path) 16KBUILD_OPTIONS := WLAN_ROOT=$(shell cd $(KERNEL_SRC); readlink -e $(M)) 17 18# MODNAME should be qca_cld3_wlan for helium based wear target 19ifeq (qca_cld3, $(WLAN_WEAR_CHIPSET)) 20KBUILD_OPTIONS += MODNAME?=$(WLAN_WEAR_CHIPSET)_wlan 21else 22KBUILD_OPTIONS += MODNAME?=wlan 23endif 24 25#By default build for CLD 26WLAN_SELECT := CONFIG_QCA_CLD_WLAN=m 27KBUILD_OPTIONS += CONFIG_QCA_WIFI_ISOC=0 28KBUILD_OPTIONS += CONFIG_QCA_WIFI_2_0=1 29KBUILD_OPTIONS += $(WLAN_SELECT) 30KBUILD_OPTIONS += $(KBUILD_EXTRA) # Extra config if any 31endif 32 33all: 34 $(MAKE) -C $(KERNEL_SRC) M=$(M) modules $(KBUILD_OPTIONS) 35 36modules_install: 37 $(MAKE) INSTALL_MOD_STRIP=1 M=$(M) -C $(KERNEL_SRC) modules_install 38 39clean: 40 $(MAKE) -C $(KERNEL_SRC) M=$(M) clean $(KBUILD_OPTIONS) 41
