159# The build system exposes several variables for where to find the kernel
160# headers:
161#   TARGET_DEVICE_KERNEL_HEADERS is automatically created for the current
162#       device being built. It is set as $(TARGET_DEVICE_DIR)/kernel-headers,
163#       e.g. device/samsung/tuna/kernel-headers. This directory is not
164#       explicitly set by anyone, the build system always adds this subdir.
165#
166#   TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file
167#       to allow other directories to be included. This is useful if there's
168#       some common place where a few headers are being kept for a group
169#       of devices. For example, device/<vendor>/common/kernel-headers could
170#       contain some headers for several of <vendor>'s devices.
171#
172#   TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance
173#       graph. This allows architecture products to provide headers for the
174#       devices using that architecture. For example,
175#       hardware/ti/omap4xxx/omap4.mk will specify
176#       PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4
177#       specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers.
178#       The build system then combines all the values specified by all the
179#       PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance
180#       tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable.
181#
182# The layout of subdirs in any of the kernel-headers dir should mirror the
183# layout of the kernel include/ directory. For example,
184#     device/samsung/tuna/kernel-headers/linux/,
185#     hardware/ti/omap4xxx/kernel-headers/media/,
186#     etc.
187#
188# NOTE: These directories MUST contain post-processed headers using the
189# bionic/libc/kernel/clean_header.py tool. Additionally, the original kernel
190# headers must also be checked in, but in a different subdirectory. By
191# convention, the originals should be checked into original-kernel-headers
192# directory of the same parent dir. For example,
193#     device/samsung/tuna/kernel-headers            <----- post-processed
194#     device/samsung/tuna/original-kernel-headers   <----- originals
