It can either be an absolute or a 5b4f780f7SSrinivas Girigowda# relative path. If it is a relative path, then it must be relative to the 6b4f780f7SSrinivas Girigowda# kernel source directory (KERNEL_SRC). An absolute path can be obtained very 7b4f780f7SSrinivas Girigowda# easily through $(shell pwd). Generating a path relative to KERNEL_SRC is 8b4f780f7SSrinivas Girigowda# difficult and we accept some outside help by letting the caller override the 9b4f780f7SSrinivas Girigowda# variable $(M). Allowing a relative path for $(M) enables us to have the build 10b4f780f7SSrinivas Girigowda# system put output/object files (.o, .ko.) into a directory different from the 11b4f780f7SSrinivas Girigowda# module source directory. 12b4f780f7SSrinivas GirigowdaM ?= $(shell pwd) 13b4f780f7SSrinivas Girigowda 1422505718SJeff Johnsonifeq ($(WLAN_ROOT),) 15b4f780f7SSrinivas Girigowda# WLAN_ROOT must contain an absolute path (i.e. not a relative path) 16b4f780f7SSrinivas GirigowdaKBUILD_OPTIONS := WLAN_ROOT=$(shell cd $(KERNEL_SRC); readlink -e $(M)) 1753dc3b7cSSrikanth Marepalli 18*e2e3e032SSrikanth Marepalli# MODNAME should be qca_cld3_wlan for helium based wear target 19*e2e3e032SSrikanth Marepalliifeq (qca_cld3, $(WLAN_WEAR_CHIPSET)) 20*e2e3e032SSrikanth MarepalliKBUILD_OPTIONS += MODNAME?=$(WLAN_WEAR_CHIPSET)_wlan 2153dc3b7cSSrikanth Marepallielse 222935d25dSMahesh Kumar Kalikot VeetilKBUILD_OPTIONS += MODNAME?=wlan 2353dc3b7cSSrikanth Marepalliendif 247090c5fdSPrakash Dhavali 257090c5fdSPrakash Dhavali#By default build for CLD 267090c5fdSPrakash DhavaliWLAN_SELECT := CONFIG_QCA_CLD_WLAN=m 277090c5fdSPrakash DhavaliKBUILD_OPTIONS += CONFIG_QCA_WIFI_ISOC=0 287090c5fdSPrakash DhavaliKBUILD_OPTIONS += CONFIG_QCA_WIFI_2_0=1 297090c5fdSPrakash DhavaliKBUILD_OPTIONS += $(WLAN_SELECT) 307090c5fdSPrakash DhavaliKBUILD_OPTIONS += $(KBUILD_EXTRA) # Extra config if any 3122505718SJeff Johnsonendif 327090c5fdSPrakash Dhavali 337090c5fdSPrakash Dhavaliall: 34b4f780f7SSrinivas Girigowda $(MAKE) -C $(KERNEL_SRC) M=$(M) modules $(KBUILD_OPTIONS) 357090c5fdSPrakash Dhavali 367090c5fdSPrakash Dhavalimodules_install: 37b4f780f7SSrinivas Girigowda $(MAKE) INSTALL_MOD_STRIP=1 M=$(M) -C $(KERNEL_SRC) modules_install 387090c5fdSPrakash Dhavali 397090c5fdSPrakash Dhavaliclean: 4099f4994cSNirav Shah $(MAKE) -C $(KERNEL_SRC) M=$(M) clean $(KBUILD_OPTIONS) 41
