Feature Table加载原理和调试方法

[FAQ14389] Feature Table加载原理和调试方法

[QUESTION]

  不同branch的feature table的位置可能略有不同，在修改和调试过程中，可能对于加载机制有所疑惑

 

[DESCRIPTION]

 

   1  Feature Table文件的位置：   vendor/mediatek/proprietary/custom//hal/sendepfeature//config.ftbl..h

   因为历史原因，有的会位于vendor/mediatek/proprietary/custom//hal/imgsensor//config.ftbl..h

  

   2  如何确定Feature Table的位置究竟在哪里？

    vendor/mediatek/proprietary/hardware/matkcam/v1/common/paramsmgr/feature/custom/Android.mk

    此文件是如何编译feature table静态库的makefile.

    会有类似如下的语句：

    ifeq ($(wildcard $(MTK_PATH_CUSTOM)/hal/sendepfeature), )

       MY_CUST_FTABLE_PATH +=  $(MTK_PATH_CUSTOM_PLATFORM)/hal/sendepfeature
    endif

    这说明使用的是hal/sendepfeature目录里面的feature table文件。

   

   3 Feature Table文件是如何被编译的？

      如上面的makefile,  它的执行是：

      在指定的目录中寻找feature table文件，并把这些头文件加上#include 字样写到一个中间头文件custgen.config.ftbl.h，此中间头文件会被custom.cpp包含，最终编译到libcam.paramsmgr.feature.custom.a中.

   

 define my-all-config.ftbl-under
$(patsubst ./%,%, \
 $(shell find $(1) -maxdepth 1 \( -name "config.ftbl.*.h" \) -and -not -name ".*") \
 )
endef

 MY_CUST_FTABLE_FILE_LIST := $(call my-all-config.ftbl-under, $(MY_CUST_FTABLE_PATH))

LOCAL_MODULE := libcam.paramsmgr.feature.custom
LOCAL_MODULE_CLASS := STATIC_LIBRARIES
INTERMEDIATES := $(call local-intermediates-dir)
# custom feature table all-in-one file
MY_CUST_FTABLE_FINAL_FILE := $(INTERMEDIATES)/custgen.config.ftbl.h
LOCAL_GENERATED_SOURCES += $(MY_CUST_FTABLE_FINAL_FILE)
$(MY_CUST_FTABLE_FINAL_FILE): $(MY_CUST_FTABLE_FILE_LIST)
 @mkdir -p $(dir $@)
 @echo '//this file is auto-generated; do not modify it!' > $@
 @echo '#define MY_CUST_VERSION "$(MY_CUST_VERSION)"' >> $@
 @echo '#define MY_CUST_FTABLE_FILE_LIST "$(MY_CUST_FTABLE_FILE_LIST)"' >> $@
 @for x in $(MY_CUST_FTABLE_FILE_LIST); do echo "#include <`basename $$x`>" >> $@; done

#-----------------------------------------------------------
include $(BUILD_STATIC_LIBRARY)

  

  4 如何快速调试feature table?

  最终feature table静态库会被编译到libcam.paramsmgr.so中。

  具体的编译为：

 

 touch vendor/mediatek/proprietary/hardware/mtkcam/v1/common/paramsmgr/feature/custom/custom.cpp && \
 mmm -j24 vendor/mediatek/proprietary/hardware/mtkcam/v1/common/paramsmgr/ 2>&1 | tee ft.lib.log && \
 mmm -j24 vendor/mediatek/proprietary//hardware/mtkcam/v1/common/paramsmgr 2>&1 | tee ft.so.log

   最后把生成的libcam.paramsmgr.so 根据32位或者64位push到设备的/system/lib目录或者/system/lib64目录中。

   一般，目前camera app使用的是32位的目录/system/lib.

  因为此动态库是mediaserver加载，用如下命令重启mediaserver来重新加载feature table:

  adb shell stop media && adb shell start media

 

  如果是调试camera app, 请先关闭camera app, 避免app缓存了feature table信息导致调试不生效。

 

  5 从log中如何查看feature table是否生效？

   您可以在log中搜索MtkCam/ParamsManager来确定是否生效，也可以搜索"s8Symbols="来确定加载的是否是指定sensor的feature table.

   "s8Symbols="的log信息来源于Feature.extern.cpp queryCustomFeature函数。

 

  6  深入了解feature table的机制：

   请在vendor/mediatek/proprietary/hardware/mtkcam/v1/common/paramsmgr/feature/custom/Android.mk中增加LOCAL_CFLAGS += -E 来获取custom.cpp预处理后feature table头文件的信息。

  编译feature table静态库，最终会保存在out/target/product//obj/STATIC_LIBRARIES/libcam.paramsmgr.feature.custom_intermediates/custom.o
