说明： 基于device/soc/hisilicon/ss928v100/sdk_linux主要是基于芯片SDK的适配，下面将展开详细介绍：

该目录下的smp和open_source目录内容为芯片SDK提供内容，可以直接从SDK中拷贝使用

ss928v100_sdk_patch_001.patch和ss928v100_sdk_patch_002.patch：由于SDK和OpenHarmony代码、编译环境差异，需要在OpenHarmony下应用定制补丁

uboot：已提供源码，需自行编译生成

SDK编译适配¶

配置OpenHarmony环境上编译芯片SDK的相关参数。

修改文件device/soc/hisilicon/ss928v100/sdk_linux/BUILD.gn，配置芯片SDK编译的相关参数。

ohos_root_path：OpenHarmony源码目录；
outdir：编译out目录；
y：是否为Lite型系统；
clang_dir：编译工具链路径；
linux_kernel_version：指定使用的内核版本；
chip：芯片型号。

if (defined(ohos_lite)) {
  build_ext_component("sdk_make") {
    exec_path = rebase_path(".", root_build_dir)
    outdir = rebase_path("$root_out_dir")
    clang_dir = ""
    if (ohos_build_compiler_dir != "") {
      clang_dir = rebase_path("$ohos_build_compiler_dir")
    }
    chip = "ss928v100"
    if (board_name == "hispark_ss927v100") {
      chip = "ss927v100"
    }
    command = "./build.sh ${ohos_root_path} ${outdir} y ${clang_dir} ${linux_kernel_version} ${chip}"
    deps = [ "//kernel/linux/build:linux_kernel" ]
  }
  not_needed(sdk_modules_name_list)
} else {
  sdk_tmp_root_path = root_out_dir
  sdk_tmp_dir = "$sdk_tmp_root_path/sdk_linux/src_tmp"
  sdk_tmp_mods_dir = "$sdk_tmp_dir/out/ko"
...

配置SDK编译工具链。

SDK包中提供内核驱动源码和Sample源码，可以通过源码进行编译。在编译前，需要配置编译工具链，将编译工具链路径加入到环境变量中。

将Clang编译工具链路径加到环境变量中，执行：export PATH=/path/to/toolchains:$PATH

例如，Clang所在的路径为/path/to/llvm_clang/bin，则执行：export PATH=/path/to/llvm_clang/bin:$PATH

在OpenHarmony环境上编ko和atf。

修改device/soc/hisilicon/ss928v100/sdk_linux/build.sh

set -e
OHOS_ROOT_PATH=$1
OUTDIR=$2
OHOS_LITE=$3
COMPILER_DIR=$4
CHIP=$6

export KERNEL_VERSION="$5"

if [ -z "${OHOS_ROOT_PATH}" ];then
    OHOS_ROOT_PATH=$(pwd)/../../../..
else
    echo "OHOS_ROOT_PATH=${OHOS_ROOT_PATH}"
fi

export OHOS_ROOT_PATH
if [ ${COMPILER_DIR} != "" ];then
    export COMPILER_PATH=${COMPILER_DIR}/bin

...

pushd ${SDK_LINUX_SMP_PATH}/a55_linux/mpp/out/lib
for lib_name in "${sdk_libs_name_set[@]}"; do
    if [ -f "$lib_name" ]; then
        cp -f $lib_name ${OUTDIR}
    fi
done
popd

mkdir -p ${SDK_LINUX_TMP_PATH}/out
cp -rf ${SDK_LINUX_SMP_PATH}/a55_linux/mpp/out/ko ${SDK_LINUX_TMP_PATH}/out

# copy images and burn_table file
cp -rf ${SDK_LINUX_SRC_PATH}/../burn/* ${OUTDIR}
# cp uImage，exe atf, flip.bin改名uImage，并替换掉；
cp -rf ${SDK_LINUX_OPEN_PATH}/trusted-firmware-a/trusted-firmware-a-2.2/build/${CHIP}/release/fip.bin ${OUTDIR}
# $(hide) cp -rf $(KERNEL_OBJ_TMP_PATH)/arch/$(KERNEL_ARCH)/boot/uImage $(OUT_DIR)

说明：

此处重点关注几个关键变量：OHOS_ROOT_PATH、COMPILER_PATH、SYSROOT_PATH

编译生成的ko和fip.bin后，会拷贝到outdir下面，最终会一起打包进rootfs

编译SDK sample。

进入sdk/smp/a55_linux/mpp/sample，执行：make

编译完成后，各sample可执行文件位于sdk/smp/a55_linux/mpp/sample对应的目录下。
说明： sample中使用了SDK_init和SDK_exit来进行MPP各个模块的初始化和退出。hnr需要使用pqp模块，SDK_init中默认未初始化pqp模块，因此需要单独对hnr的sample进行重编，具体步骤为：
1. 将sdk/smp/a55_linux/mpp/sample/common/sdk_module_init.h头文件中的宏定义INIT_PQP修改为1；
2. 进入hnr目录重编，命令如下。
cd sdk/smp/a55_linux/mpp/sample/hnr make clean make

SDK打包进文件系统¶

修改文件device/soc/hisilicon/ss928v100/sdk_linux/BUILD.gn，将芯片SDK自带的用户态lib库文件拷贝进outdir中，从而被打包进rootfs中。

sdk_libs_name_set:为在OpenHarmony环境上运行SDK Sample所必须依赖的用户态lib库文件。

#####################################################################
sdk_libs_name_set = [
  "libaac_comm.so",
  "libaac_dec.so",
  "libaac_enc.so",
  "libaac_sbr_dec.so",
  "libaac_sbr_enc.so",
  "libaiv.so",
...
]

if (defined(ohos_lite)) {
  lib_lite_abspath = rebase_path("$SDK_LINUX_LIB_LITE_PATH", ".")
  sdk_linux_libs_targets = []

  foreach(lib, sdk_libs_name_set) {
    copy("$lib") {
      sources = [ "$lib_lite_abspath/$lib" ]
      outputs = [ "$root_out_dir/$lib" ]
    }
    sdk_linux_libs_targets += [ ":$lib" ]
  }

  group("sdk_linux_lite_libs") {
    deps = sdk_linux_libs_targets
  }
} else {
  not_needed([
               SDK_LINUX_LIB_LITE_PATH,
               SDK_LINUX_PATH,
             ])
  not_needed(sdk_libs_name_set)
}

修改文件third_party/musl/scripts/build_lite/BUILD.gn，将运行SDK lib库文件依赖的编译器库文件打包进文件系统。

 if (!is_llvm_build) {
    # copy C/C++ runtime libraries to lib out dir
    if (ohos_build_compiler == "clang") {
      runtime_libs = [
        "libc++.so",
        "libc.so",
        "libomp.so",
      ]
      compiler_cmd = "$ohos_current_cxx_command --target=$target_triple --sysroot=$sysroot_path $arch_cflags"
    }

ko和fip.bin已经在SDK编译适配说明。

Linux内核适配¶

OpenHarmony 5.1.0 Release的和SS928V100 sdk的内核均是来源于Linux-6.6，内核适配主要是兼容2种内核代码差异，代码模型如图1所示。

kernel/linux/config

新增kernel/linux/config/linux-6.6/arch/arm64/configs/hispark_ss928v100_small_defconfig
kernel/linux/patches

新增如下patch目录kernel/linux/patches/linux-6.6/hispark_ss928v100_patch，目录结构规划如下。

hispark_ss928v100_patch       #ss928 sdk集成oh内核后的patch
├── oh_feature.patch       #OH特性的内核部分patch，和sdk内核代码不存在冲突
├── oh_ss928.patch         #OH特性和ss928 sdk内核特性合并patch
└── patch_ss928v100.sh     #执行应用patch脚本文件

内核编译调试¶

在OpenHarmony环境下整编kernel。

在ohos代码根目录下执行命令，整编Linux-6.6内核。
```
./build.sh --product-name=ipcamera_hispark_ss928v100_linux  --build-target linux_kernel  --ccache --no-prebuilt-sdk
```
说明： OpenHarmony支持多套内核版本Linux-5.10、Linux-6.6，默认匹配最高的内核版本；若要指定Linux-5.10 内核版本可以增加参数--gn-args linux_kernel_version=\"linux-5.10\"。可以参考kernel/linux/build/README_zh.md文档编译。
直接使用Makefile编译调试kernel。

通过在kernel/linux/build/BUILD.gn中增加编译kernel的command打印出来，从而实现手动调试Makefile，加粗部分为修改代码。

if (os_level == "mini" || os_level == "small") {
  build_ext_component("linux_kernel") {
    no_default_deps = true
    exec_path = rebase_path(".", root_build_dir)
    outdir = rebase_path("$root_out_dir")
    build_type = "small"
    product_path_rebase = rebase_path(product_path, ohos_root_path)
    command = "./kernel_module_build.sh ${outdir} ${build_type} ${target_cpu} ${product_path_rebase} ${board_name} ${linux_kernel_version}"
    print("++++++++ command: $command")
  }

在ohos目录下整编一次产品。
```
./build.sh --product-name=ipcamera_hispark_ss928v100_linux  --build-target linux_kernel  --ccache --no-prebuilt-sdk
```
在out/hispark_ss928v100/ipcamera_hispark_ss928v100_linux/build.log中查找步骤1增加打印，找到执行命令。
在Linux终端下进入kernel/linux/build目录，执行上述步骤1中打印出的调试编译内核的命令即可触发编译。

XTS最小集子系统适配¶

OpenHarmony子系统适配只需要在vendor/hisilicon/hispark_ss928v100_linux/config.json中增加对应子系统和部件，这样编译系统会将该部件纳入编译目标中。

本章节主要介绍SS928V100适配L1（不带屏）设备满足XTS认证的依赖的子系统集，如下仅提供参考。

添加系统启动服务配置¶

修改vendor/hisilicon/hispark_ss928v100_linux/init_configs/init_linux_openharmony.cfg新增启动服务。

                "start ueventd",
                "start shell",
                "start apphilogcat",
                "start foundation",
                "start bundle_daemon",
                "start faultloggerd",
                "start devattest_service",
                "start huks_server"

子系统部件适配SS928V100¶

参照添加依赖的OpenHarmony子系统集，适配SS928V100修改、解决编译问题。

修改acts编译gn文件¶

修改test/xts/acts/build_lite/BUILD.gn文件，注释第106行和107行，ActsBundleMgrTest和ActsAbilityMgrTest为带屏设备需要。

    } else if (ohos_kernel_type == "linux") {
      all_features += [
        "//test/xts/acts/distributeddatamgr_lite/kv_store_posix:ActsKvStoreTest",
        "//test/xts/acts/startup_lite/syspara_posix:ActsParameterTest",
        "//test/xts/acts/startup_lite/bootstrap_posix:ActsBootstrapTest",
        "//test/xts/acts/communication_lite/lwip_posix:ActsLwipTest",
        "//test/xts/acts/security_lite:securitytest",

        #"//test/xts/acts/multimedia_lite/camera_lite_posix/camera_native:ActsMediaCameraTest",
        #"//test/xts/acts/multimedia_lite/media_lite_posix/player_native:ActsMediaPlayerTest",
        #"//test/xts/acts/multimedia_lite/media_lite_posix/recorder_native:ActsMediaRecorderTest",

        "//test/xts/acts/xts_lite/device_attest_lite/device_attestStart_posix:ActsDeviceAttestStartTest",
        "//test/xts/acts/xts_lite/device_attest_lite/device_attestQuerry_posix:ActsDeviceAttestQuerryTest",
      ]
    }

XTS测试用例问题修复¶

修改test/xts/acts/distributed_schedule_lite/system_ability_manager_posix/src/LiteIPCClientTest.cpp文件, 原生代码如下：

此用例是因为了验证SAMGR_GetRemoteIdentity接口当服务不存在时获取到无效的IPC服务地址，因此加粗部分svcIdentity.token返回的是一个无效指针数据值为-1，在64位系统下占用8个字节，与0xffffffff做相等比较时会导致用例无法有效执行。

HWTEST_F(LiteIPCClientTest, testIPCClient0130, Function | MediumTest | Level2)
{
    SvcIdentity svcIdentity = SAMGR_GetRemoteIdentity("noExistService", "noExistFeature");
    ASSERT_EQ(svcIdentity.handle == 0xffffffff, TRUE);
    ASSERT_EQ(svcIdentity.token == 0xffffffff, TRUE);
};

修改后代码如下：

HWTEST_F(LiteIPCClientTest, testIPCClient0130, Function | MediumTest | Level2)
{
    SvcIdentity svcIdentity = SAMGR_GetRemoteIdentity("noExistService", "noExistFeature");
    ASSERT_EQ(svcIdentity.handle == 0xffffffff, TRUE);
    // token type is uintptr_t
    ASSERT_EQ(svcIdentity.token == INVALID_INDEX, TRUE);
};

xts工具问题修复¶

修改test/xts/tools/lite/build/suite.py文件，源生代码如下：

说明： 此部分代码是用于将编译打包xdevice工具打包，当前编译生成的xdevice-0.0.0-py3.11.egg和xdevice_ohos-0.0.0-py.3.11.egg文件安装默认时，默认会从外网下载xdevice，用户若能正常下载可跳过此章节。

class XDeviceBuilder:
    """
    To build XTS as a egg package
    @arguments(project_dir, output_dirs)
    """

    def __init__(self, arguments):
        parser = argparse.ArgumentParser()
        parser.add_argument('--project_dir', help='', required=True)
        parser.add_argument('--output_dirs', help='', required=True)
        self.args = parser.parse_args(arguments)

    def build_xdevice(self):
        """
        build xdevice package
        :return:
        """
        ohos_dir = os.path.join(self.args.project_dir, 'plugins', 'ohos')
        command = [utils.get_python_cmd(), "setup.py", "install", "--user"]
        factory_script = os.path.join(self.args.project_dir, "factory.sh")
        if os.path.exists(factory_script):
            os.chmod(factory_script, 0o775)
            command = factory_script

可将xdevice打包改成tar.gz文件格式打包工具。

command = [utils.get_python_cmd(), "setup.py", "sdist"]

带屏XTS最小集子系统适配¶

修改acts编译gn文件¶

修改test/xts/acts/build_lite/BUILD.gn文件，放开第106行和107行参与acts套件编译，ActsBundleMgrTest和ActsAbilityMgrTest为带屏设备需要。

    } else if (ohos_kernel_type == "linux") {
      all_features += [
        "//test/xts/acts/distributeddatamgr_lite/kv_store_posix:ActsKvStoreTest",
        "//test/xts/acts/startup_lite/syspara_posix:ActsParameterTest",
        "//test/xts/acts/startup_lite/bootstrap_posix:ActsBootstrapTest",
        "//test/xts/acts/communication_lite/lwip_posix:ActsLwipTest",
        "//test/xts/acts/security_lite:securitytest",

        #"//test/xts/acts/multimedia_lite/camera_lite_posix/camera_native:ActsMediaCameraTest",
        #"//test/xts/acts/multimedia_lite/media_lite_posix/player_native:ActsMediaPlayerTest",
        #"//test/xts/acts/multimedia_lite/media_lite_posix/recorder_native:ActsMediaRecorderTest",
        "//test/xts/acts/distributed_schedule_lite/system_ability_manager_posix:ActsSamgrTest",
       "//test/xts/acts/appexecfwk_lite/appexecfwk_posix:ActsBundleMgrTest",
       "//test/xts/acts/ability_lite/ability_posix:ActsAbilityMgrTest",
        "//test/xts/acts/ai_lite/ai_engine_posix/base:ActsAiEngineTest",
        "//test/xts/acts/xts_lite/device_attest_lite/device_attestStart_posix:ActsDeviceAttestStartTest",
        "//test/xts/acts/xts_lite/device_attest_lite/device_attestQuerry_posix:ActsDeviceAttestQuerryTest",
      ]
    }

config.json中添加依赖子系统¶

在vendor/hisilicon/hispark_ss928v100_linux/config.json中增加ability子系统，为带屏测试套件编译所需。

    {
      "subsystem": "ability",
      "components": [
        { "component": "ability_lite", "features":[ "ability_lite_enable_ohos_appexecfwk_feature_ability = true" ] },
        { "component": "dmsfwk_lite", "features":[] }
      ]
    },

添加系统启动服务配置¶

修改vendor/hisilicon/hispark_ss928v100_linux/init_configs/init_linux_openharmony.cfg新增启动服务，加粗部分为新增修改。

                "start ueventd",
                "start shell",
                "start apphilogcat",
                "start foundation",
                "start bundle_daemon",
              "start appspawn",
                "start faultloggerd",
                "start devattest_service",
                "start huks_server"

完成以上修改acts编译gn文件至添加系统启动服务配置操作就可以运行L1带屏设备的acts套件，若遇到执行ActsAbilityMgrTest模块卡死情况，则需要适配security_appverify组件，解决hap校验问题即可。

xts测试用例问题修复¶

修改test/xts/acts/ability_lite/ability_posix/src/AbilityMgrTest.cpp测试用例，源生代码如下：

此用例是因为了验证DisConnectAbility接口，而下述代码加粗部分g_errorcode==16为异常保护，会导致用例无法有效执行；但是DisConnectAbility和ConnectAbility要成对出现，会导致用例失败。

HWTEST_F(AbilityMgrTest, testDisConnectAbility, Function | MediumTest | Level1)
{
    printf("------start testDisConnectAbility------\n");
    Want want = { nullptr };
    ElementName element = { nullptr };
    SetElementBundleName(&element, "com.openharmony.testnative");
    SetElementAbilityName(&element, "ServiceAbility");
    SetWantElement(&want, element);
    sem_init(&g_sem, 0, 0);
    int result = ConnectAbility(&want, &g_conn, this);
    struct timespec ts = {};
    clock_gettime(CLOCK_REALTIME, &ts);
    ts.tv_sec += WAIT_TIMEOUT;
    sem_timedwait(&g_sem, &ts);
    printf("sem exit \n");
    printf("ret of connect is %d \n ", result);
    if (g_errorCode == 16) {
        result = DisconnectAbility(&g_conn);
        usleep(900000);
        EXPECT_EQ(result, 0);
        printf("ret of disconnect is %d \n ", result);
    }
    ClearElement(&element);
    ClearWant(&want);
    printf("------end testDisConnectAbility------\n");
}

估可以去掉源生g_errorcode==16，或者将DisConnectAbility和ConnectAbility场景移至最后执行，本文采取去掉异常保护，修改后代码。

HWTEST_F(AbilityMgrTest, testDisConnectAbility, Function | MediumTest | Level1)
{
    printf("------start testDisConnectAbility------\n");
    Want want = { nullptr };
    ElementName element = { nullptr };
    SetElementBundleName(&element, "com.openharmony.testnative");
    SetElementAbilityName(&element, "ServiceAbility");
    SetWantElement(&want, element);
    sem_init(&g_sem, 0, 0);
    int result = ConnectAbility(&want, &g_conn, this);
    struct timespec ts = {};
    clock_gettime(CLOCK_REALTIME, &ts);
    ts.tv_sec += WAIT_TIMEOUT;
    sem_timedwait(&g_sem, &ts);
    printf("sem exit \n");
    printf("ret of connect is %d \n ", result);
    result = DisconnectAbility(&g_conn);
    usleep(900000);
    EXPECT_EQ(result, 0);
    printf("ret of disconnect is %d \n ", result);
    ClearElement(&element);
    ClearWant(&want);
    printf("------end testDisConnectAbility------\n");
}

单步调试xts的testcase¶

本小节主要介绍xts测试过程中，出现卡死或单个testcase执行失败场景，定位具体用例失败原因。

以ActsAbilityMgrTest为例说明。重新NFS挂载好单板后，在板端执行观察用例执行情况。

./ActsAbilityMgrTest.bin --gtest_output=xml:/storage/test_root/aafwk/reportsn --gtest_output=xml:/storage/test_root/aafwk/reports 

图形¶

OpenHarmony增加图形子系统，需要在vendor/hisilicon/hispark_ss928v100_linux/config.json中增加对应子系统和部件，同时在device/soc/hisilicon目录中是芯片相关的适配，其中图形的适配代码存在于device/soc/hisilicon/common/hal/display中。

config.json中新增图形子系统依赖的部件¶

在vendor/hisilicon/hispark_ss928v100_linux/config.json文件，"subsystems"标签中添加如下代码：

    {
        "subsystem": "arkui",
        "components": [
            { "component": "ui_lite", "features":[ "ui_lite_enable_graphic_font_config = true" ] }
        ]
    },
    {
        "subsystem": "graphic",
        "components": [
           { "component": "graphic_utils_lite", "features":[] },
           { "component": "surface_lite", "features":[] }
        ]
    },
    {
        "subsystem": "window",
        "components": [
            { "component": "window_manager_lite", "features":[] }
        ]
    }

device/soc/hisilicon下新增SS928V100图形相关驱动代码¶

在device/soc/hisilicon/common/hal/display下新增SS928V100目录，用于放置SS928V100图形驱动相关代码。图形驱动HDI接口的整体介绍可以参考drivers/peripheral/display/README_zh.md文档中的描述。

**注意：**相比于Hi3516DV300芯片适配，SS928V100的sdk经过用户态整改后，需要在用户态先执行sdk各模块的init操作，再调用sdk接口。如果只启动图形功能，需要在InitDisplay里调用SdkInit完成几个模块的初始化接口调用：

static void SdkInit()
{
    td_s32 ret;
    ret = osal_init();
    if (ret != 0) {
        HDF_LOGE("%s: osal_init error:%d", __func__, ret);
    }
    ret = ot_base_mod_init();
    if (ret != 0) {
        HDF_LOGE("%s: BaseModInit error:%d", __func__, ret);
    }
    ret = ot_sys_mod_init();
    if (ret != 0) {
        HDF_LOGE("%s: SysModInit error:%d", __func__, ret);
    }
    ret = ot_rgn_mod_init();
    if (ret != 0) {
        HDF_LOGE("%s: ot_rgn_mod_init error:%d", __func__, ret);
    }
    ret = ot_vo_mod_init();
    if (ret != 0) {
        HDF_LOGE("%s: VoModInit error:%d", __func__, ret);
    }
}

同时，需要在DeinitDisplay函数里调用SdkExit完成去初始化：

static void SdkExit()
{
    ot_vo_mod_exit();
    ot_rgn_mod_exit();
    ot_sys_mod_exit();
    ot_base_mod_exit();
    osal_exit();
}

device/soc/hisilicon下SS928V100驱动代码编译适配¶

在device/soc/hisilicon/common/hal/display/BUILD.GN里增加SS928V100的编译命令：

if (board_name == "hispark_ss928v100" || board_name == "hispark_ss927v100") {

}

图形服务开机自启动适配¶

在vendor/hisilicon/hispark_ss928v100_linux/init_configs/init_linux_openharmony.cfg中增加图形子系统的启动命令，并修改图形服务的启动权限，可以在单板商店后自动启动图形服务。

在"cmds"中增加如下行：

    "start wms_server",

由于SDK用户态整改，图形子系统调用sdk部分接口打开/dev下设备时需要增加权限，在“services”中找到name为wms_server的项，修改caps如下：

    {
        "name" : "wms_server",
        "path" : ["/bin/wms_server"],
        "uid" : 10,
        "gid" : 10,
        "once" : 1,
        "importance" : 0,
        "caps" : [1, 17, 21, 23]
    }

媒体¶

OpenHarmony增加媒体子系统，需要在vendor/hisilicon/hispark_ss928v100_linux/config.json中增加对应子系统和部件，同时在device/soc/hisilicon目录中是芯片相关的适配，其中图形的适配代码存在于device/soc/hisilicon/common/hal/media中。

config.json中新增媒体子系统依赖的部件¶

在vendor/hisilicon/hispark_ss928v100_linux/config.json文件，"subsystems"标签中添加如下代码：

    {
        "subsystem": "multimedia",
        "components": [

device/soc/hisilicon下适配SS928V100媒体代码¶

在device/soc/hisilicon/common/hal/media下新增SS928V100目录，用于放置SS928V100媒体相关适配代码。

**注意：**相比于Hi3516DV300芯片适配，SS928V100的sdk经过用户态整改后，需要在用户态先执行sdk各模块的init操作，再调用sdk接口。启动媒体功能，需要在HalCameraInit里调用SDK_init完成几个模块的初始化接口调用，并对应地在HalCameraDeinit调用SDK_exit完成去初始化，如下图所示：

在对应的device/soc/hisilicon/common/hal/media/camera/source/BUILD.gn文件中新增对sdk发布的部分so的依赖：
