RDA 多屏参流程

一、RDA MAKEFILE的本地变量

　　在介绍多屏参之前，先看一下./code/env.conf的包含过程，通过./code/Makefile.project加载，env.conf中所有的变量，都变为makefile执行过程中的本地变量：

包括：mconfig.config、boardconfig.config、menuconfig.config文件中变量的定义，所以在任何递归的Makefile都可以引用这三个文件定义的变量，关于mconfig.config定义的屏参，在aps/customer/Makefile会通过变量$(CONFIG_PANEL_TYPE)进行引用。

include $(ROOT_DIR)/mconfig.config
include $(ROOT_DIR)/boardconfig.config
include $(ROOT_DIR)/menuconfig.config

APP_FOLDER_NAME=$(subst ",,$(CONFIG_APP_FOLDER_NAME))
CUSTOMER_NAME=$(subst ",,$(CONFIG_CUSTOMER_NAME))
SUBCUSTOMER_NAME=$(subst ",,$(CONFIG_SUBCUSTOMER_NAME))
SUBSUBCUSTOMER_NAME=$(subst ",,$(CONFIG_SUBSUBCUSTOMER_NAME))
BOARD_NAME=$(subst ",,$(CONFIG_MODEL_BOARD_NAME))
PANEL_NAME=$(subst ",,$(CONFIG_PANEL_TYPE_NAME))

APPDIR_NAME=$(CUSTOMER_NAME)/$(APP_FOLDER_NAME)
CUSTOMER_BOARD_PATH=customer/$(CUSTOMER_NAME)/$(BOARD_NAME)
FORMAL_CUSTOMER_PATH=customer/$(CUSTOMER_NAME)/sub_customer/$(SUBCUSTOMER_NAME)/$(SUBSUBCUSTOMER_NAME)

mconfig.config中多屏参的定义：

CONFIG_PANEL_TYPE_PN_FAC_1366X768="PN_FAC_1366x768"
CONFIG_PANEL_TYPE_PN_FAC_1440X900="PN_FAC_1440x900"
CONFIG_PANEL_TYPE_PN_FAC_1920X1080="PN_FAC_1920x1080"
CONFIG_PANEL_TYPE_CMO_M185B1_L02_1366X768="CMO_M185B1_L02_1366x768"
CONFIG_PANEL_CMO_M185B1_L02_1366X768_IS_DEFAULT=y
CONFIG_PANEL_TYPE_DEFAULT_FOLDER="CMO_M185B1_L02_1366x768"
CONFIG_DDC_DeafaultTable_1366x768=y
CONFIG_PANEL_TYPE_AUO_B141PW04_V1_1440X900="AUO_B141PW04_V1_1440x900"
CONFIG_PANEL_TYPE_AUO_T420HW04_V0_1920X1080="AUO_T420HW04_V0_1920x1080"

 

二、多屏参的形成过程

　　1、Makefile.pj 定义的"make mconfig"的执行过程，调用gen_customer.pl生产屏参目录下的makefile.ini文件：

customer:
    ./tools/gen_customer.pl -C aps/customer -E aps/external

mconfig: customer
ifndef PJ
    @[ -e $@.config ] && mv -f $@.config .config; ./tools/mconf/mconf $@.Kconfig; mv -f .config $@.config
    @NEW_CUSTOMER_NAME=`grep CONFIG_CUSTOMER_NAME $@.config | awk 'BEGIN {FS="""}{print $$2}'`; 
    NEW_SUB_NAME=`grep CONFIG_SUBCUSTOMER_NAME $@.config | awk 'BEGIN {FS="""}{print $$2}'`; 
    NEW_SUBSUB_NAME=`grep CONFIG_SUBSUBCUSTOMER_NAME $@.config | awk 'BEGIN {FS="""}{print $$2}'`;
    NEW_MODEL_BOARD_NAME=`grep CONFIG_MODEL_BOARD_NAME $@.config | awk 'BEGIN {FS="""}{print $$2}'`;
    NEW_CUSTOMER_BOARD_PATH=customer/$${NEW_CUSTOMER_NAME}/$${NEW_MODEL_BOARD_NAME};    
    NEW_FORMAL_CUSTOMER_PATH=customer/$${NEW_CUSTOMER_NAME}/sub_customer/$${NEW_SUB_NAME}/$${NEW_SUBSUB_NAME};    
    [ -e aps/$${NEW_CUSTOMER_BOARD_PATH}/boardconfig.config ] && cp -f aps/$${NEW_CUSTOMER_BOARD_PATH}/boardconfig.config boardconfig.config; 
    cp -f aps/$${NEW_FORMAL_CUSTOMER_PATH}/project/DEFAULT.config menuconfig.config;    
endif

　　“gen_customer.pl”主要功能是：创建make mconfig UI界面显示的信息。如下的的Kconfig文件，均由“gen_customer.pl”产生。

./code/aps/customer/radisson/public/ir/ir_map.h  
./code/aps/customer/radisson/public/ir/ir_map.c  
./code/aps/customer/radisson/public/ir/irinclude.in./code/aps/customer/radisson/public/ir/irsrc.in./code/aps/customer/radisson/public/ir/makefile.ini  
./code/aps/customer/radisson/public/ir/Kconfig  
./code/aps/customer/radisson/public/ir_tx/Kconfig  
./code/aps/customer/radisson/public/ir_tx/ir_txinclude.in./code/aps/customer/radisson/public/ir_tx/ir_txsrc.in./code/aps/customer/radisson/Kconfig  
./code/aps/customer/radisson/sub_customer/radisson/Kconfig  
./code/aps/customer/radisson/sub_customer/radisson/radisson/Kconfig.project  ./code/aps/customer/radisson/public/panel/Kconfig.panel  
./code/aps/customer/radisson/public/panel/makefile.ini  
./code/aps/customer/radisson/sub_customer/radisson/radisson/Kconfig  
./code/aps/customer/Kconfig.external

　　其中“./aps/customer/radisson/public/panel/makefile.ini”，为多屏参文件。“gen_customer.pl”将迭代panel下面的所有屏参目录，生成makefile.ini如下：这个文件在编译时aps/customer/Makefile会包含“makefile.ini”，运行“tools/gen_paneltable.pl”在屏参目录生成。

CONFIG_PANEL_TYPE=
$(CONFIG_PANEL_TYPE_AUO_B141PW04_V1_1440X900) 
$(CONFIG_PANEL_TYPE_AUO_T420HW04_V0_1920X1080) 
$(CONFIG_PANEL_TYPE_CMO_M185B1_L02_1366X768) 
$(CONFIG_PANEL_TYPE_PN_FAC_1366X768) 
$(CONFIG_PANEL_TYPE_PN_FAC_1440X900) 
$(CONFIG_PANEL_TYPE_PN_FAC_1920X1080)

　　这里注意：脚本的功能是将屏参文件名字大写，定义为变量名的形式，如果mconfig.config有定义，则变量有值，没有定义变量则为空。虽然makefile.ini包含了所有的屏参变量的定义，但只有在mconfig.config定义的屏参有值，在接下来的脚本gen_paneltable.pl只处理在mconfig.config中定义的屏参，这里做的很巧妙。

　　2、gen_paneltable.pl根据makefile.ini，处理需要生成的PanelSet_XXX.bin & PanelSet_Bak.bin

　　接下来的介绍aps/makefile文件的执行过程：

　　注意：终极目标“all”-->依赖“application”-->依赖“$(BUILD_MODULE) ”-->依赖“customer”-->命令行“@$(MAKE) -C customer gen_multipanelbin”-->执行aps/customer/Makefile：gen_multipanelbin

include Makefile.project

#define TOP DIR and LIB DIR
export TOP_DIR := $(shell /bin/pwd)
export LIB_DIR := $(TOP_DIR)/lib

AV_DEV_ONOFF=n
ifdef CONFIG_MEDIA_ENABLE
AV_DEV_ONOFF=y
endif
ifdef CONFIG_DTV_SUPPORT
AV_DEV_ONOFF=y
endif
ifeq ($(AV_DEV_ONOFF),y)
#av_dev (runav and mpdev)
BUILD_MODULE += av_dev
#INSTALL_MODULE += av_dev
endif

ifeq ($(CONFIG_NOT_USEBB),y)
BUILD_MODULE += minibox
endif

INSTALL_MODULE += application

#tool kits

ifeq ($(CONFIG_NOT_USEBB),$(filter $(CONFIG_NOT_USEBB),n))
BUILD_MODULE += toy
INSTALL_MODULE += toy
BUILD_MODULE += sf
INSTALL_MODULE += sf
endif

ifeq ($(CONFIG_CORE_DUMP),y)
BUILD_MODULE += automount
INSTALL_MODULE += automount
endif

ifeq ($(CONFIG_DRIVER_TEST_AP_BUILDIN),y)
BUILD_MODULE += test
INSTALL_MODULE += test
endif

include external/Makefile.in

BUILD_MODULE += gsl filesystem middleware app_infra test

ifeq (y, $(findstring y, ${CONFIG_OSD_GAME_SUPPORT}${CONFIG_SUPPORT_NES_GAME}))
BUILD_MODULE += game
endif

.PHONY: all clean install application customer $(BUILD_MODULE) 

all: application

application: $(BUILD_MODULE) 
    $(MAKE) -C application all 

clean:
    @$(MAKE) -C application clean
    @$(MAKE) -C customer clean
    @$(foreach MODULES, $(BUILD_MODULE), $(MAKE)  -C ./$(MODULES) clean ; )
    @$(MAKE) -C sf clean        

install:
ifndef CONFIG_INSTALLDIR
    @$(error [ERROR] CONFIG_INSTALLDIR not define!!)
endif
    $(MAKE) -C initramfs install
    @$(foreach MODULES, $(INSTALL_MODULE), $(MAKE)  -C ./$(MODULES) install CONFIG_INSTALLDIR=$(CONFIG_INSTALLDIR) ; )
    @$(MAKE) -C customer/$(CUSTOMER_NAME)/public/sound install

$(BUILD_MODULE): customer
    @$(MAKE) -C $@ all 

customer:
ifdef CONFIG_SUPPORT_PANNEL_PHOTO_TEST
    @$(MAKE) -C customer gen_pnltestpattern
endif
    @$(MAKE) -C customer create_buildfiles
    @$(MAKE) -C customer gen_multipanelbin
    @$(MAKE) -C customer all
ifdef  CONFIG_SUPPORT_NVM_ENABLE_AUTOUPDATEVESION_TOOL
    @$(MAKE) -C customer gen_datasetting
endif
ifdef CONFIG_SUPPORT_NES_FLASH
    @$(MAKE) -C customer gen_gamebin
endif

　　aps/customer/Makefile：gen_multipanelbin如下：调用gen_paneltable.pl

# include ir makefile
include ./$(CUSTOMER_NAME)/public/ir/makefile.ini
IR_MAP_WILLBEBUILD =    
    $(foreach file, $(IR_MAP), $(addprefix build_, $(file)))
SRCS_LIST += $(IR_MAP_WILLBEBUILD)
    
include ./$(CUSTOMER_NAME)/public/panel/makefile.ini

#***************************************************************************
#  Build binary file for drivers
#***************************************************************************
.PHONY: create_buildfiles gen_customerdata4driver all clean_loop gen_pnltestpattern  gen_datasetting gen_gamebin

create_buildfiles:
ifdef CONFIG_SUPPORT_PROJECT_ID
    @$(MAKE) -C ./$(CUSTOMER_NAME) create_buildfiles
    @$(MAKE) -C ./$(CUSTOMER_NAME) all
endif
    @../../tools/gen_customertablebefore.pl $(DRV_CUSTMERFILES_B_WITHPATH) $(DRV_CUSTMERFILES_B1_WITHPATH) $(DRV_CUSTMERFILES_B2_WITHPATH) 
　　　　$(DRV_CUSTMERFILES_C_WITHPATH) $(IR_MAP_WITHPATH)

gen_multipanelbin:
    @../../tools/gen_paneltable.pl -M "$(CONFIG_PANEL_TYPE)" -P ./$(CUSTOMER_NAME)/public/panel/ 、
　　-B ../$(CUSTOMER_BOARD_PATH)/adaptable/ -L ./$(CUSTOMER_NAME)/sub_customer/$(SUBCUSTOMER_NAME)/$(SUBSUBCUSTOMER_NAME)/logo 
    -F ./$(CUSTOMER_NAME)/public/panel/$(CONFIG_PANEL_TYPE_DEFAULT_FOLDER) 
    -V `echo $(CONFIG_CHIPID) | sed 's/0x//'` --panel_ini2bin ../../tools/pnlset2bin/pnlset2bin --VIP_ini2bin ../../tools/vip2bin/vip2bin 
    --lzma ../../tools/lzma460/lzma -I $(CONFIG_PANEL_TYPE_DEFAULT_FOLDER) -X "n"

　　“gen_paneltable.pl”根据makefile.ini定义的$(CONFIG_PANEL_TYPE)与“panel_setting.h”生成屏参目录下的“PanelSet_XXX.bin”文件，并将多屏参打包到PanelSet_Bak.bin。

三、链接到FLASH
