To reduce the start time. With the change and previous change of doing clean step in only given paths, start time of mm/mmm is reduced from ~5s to about 1s; lunch time is reduced from ~40s to 3.5s. Bug: 7186768,7169854 Change-Id: Ifd72ba1c6362a5e1125a23c505fd47947ab56675

# device being built. It is set as $(TARGET_DEVICE_DIR)/kernel-headers,
|
|
# e.g. device/samsung/tuna/kernel-headers. This directory is not
|
|
# explicitly set by anyone, the build system always adds this subdir.
|
|
#
|
|
# TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file
|
|
# to allow other directories to be included. This is useful if there's
|
|
# some common place where a few headers are being kept for a group
|
|
# of devices. For example, device/<vendor>/common/kernel-headers could
|
|
# contain some headers for several of <vendor>'s devices.
|
|
#
|
|
# TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance
|
|
# graph. This allows architecture products to provide headers for the
|
|
# devices using that architecture. For example,
|
|
# hardware/ti/omap4xxx/omap4.mk will specify
|
|
# PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4
|
|
# specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers.
|
|
# The build system then combines all the values specified by all the
|
|
# PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance
|

# tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable.
|
|
#
|

# The layout of subdirs in any of the kernel-headers dir should mirror the

# layout of the kernel include/ directory. For example,

# device/samsung/tuna/kernel-headers/linux/,
|
|
# hardware/ti/omap4xxx/kernel-headers/media/,
|
|
# etc.

# bionic/libc/kernel/clean_header.py tool. Additionally, the original kernel
|
|
# headers must also be checked in, but in a different subdirectory. By
|
|
# convention, the originals should be checked into original-kernel-headers

# device/samsung/tuna/kernel-headers <----- post-processed
