It is set as $(TARGET_DEVICE_DIR)/kernel-headers, 143# e.g. device/samsung/tuna/kernel-headers. This directory is not 144# explicitly set by anyone, the build system always adds this subdir. 145# 146# TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file 147# to allow other directories to be included. This is useful if there's 148# some common place where a few headers are being kept for a group 149# of devices. For example, device/<vendor>/common/kernel-headers could 150# contain some headers for several of <vendor>'s devices. 151# 152# TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance 153# graph. This allows architecture products to provide headers for the 154# devices using that architecture. For example, 155# hardware/ti/omap4xxx/omap4.mk will specify 156# PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4 157# specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers. 158# The build system then combines all the values specified by all the 159# PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance 160# tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable. 161# 162# The layout of subdirs in any of the kernel-headers dir should mirror the 163# layout of the kernel include/ directory. For example, 164# device/samsung/tuna/kernel-headers/linux/, 165# hardware/ti/omap4xxx/kernel-headers/media/, 166# etc. 167# 168# NOTE: These directories MUST contain post-processed headers using the 169# bionic/libc/kernel/clean_header.py tool. Additionally, the original kernel 170# headers must also be checked in, but in a different subdirectory. By 171# convention, the originals should be checked into original-kernel-headers 172# directory of the same parent dir.
