获取官方源码

# 由于iStoreOS官方源码为RK3588提供的MALI版本是g17p0-01eac0
# 现在想将其升级到BSP内核 5.10.160 中最新的版本g18p0-01eac0

# 获取来自Armbian的Rockchip BSP内核驱动
git clone --depth=1 -b rk-5.10-rkr6 https://github.com/armbian/linux-rockchip.git

# 获取iStore官方源码
git clone --depth=1 -b istoreos-22.03 https://github.com/istoreos/istoreos.git

升级内核源码

# 设置Armbian内核源码和iStore源码路径
KERNEL_PATH=/home/leux/linux-rockchip
IS_KER_PATH=/home/leux/istoreos/target/linux/rockchip/rk35xx/files

# 先删除旧版本源码
rm -rf $IS_KER_PATH/drivers/gpu/arm/*
rm -rf $IS_KER_PATH/include/uapi/gpu/arm/bifrost/
rm $IS_KER_PATH/include/linux/mali_arbiter_interface.h

rm $IS_KER_PATH/include/linux/protected_memory_allocator.h
rm $IS_KER_PATH/include/linux/protected_mode_switcher.h
rm $IS_KER_PATH/include/linux/version_compat_defs.h

# 拷贝MALI驱动到iStoreOS源码

# 拷贝依赖的头文件到iStoreOS源码

修改内核配置

# 首先 make clean 清除缓存，然后再 make V=s -j$(nproc)，等 Restart config... 提示出来时
# 根据需求配置，将 Restart config... 多出来的配置加入：istoreos/target/linux/rockchip/rk35xx/config-5.10

# 将如下两行加到 CONFIG_MALI_BIFROST_EXPERT=y 后面来自动跳过编译时的 `Restart config...`
# CONFIG_LARGE_PAGE_ALLOC_OVERRIDE is not set
# CONFIG_LARGE_PAGE_ALLOC is not set

升级内核固件

# 将 package/firmware/mali-csf-firmware/Makefile 中下面相关修改成如下内容：
PKG_VERSION:=g18p0-01eac0
PKG_SOURCE_VERSION:=ca33693a03b2782edc237d1d3b786f94849bed7d
PKG_HASH:=122f1ecc14d2de0fe93fc025f8c77e4531abd004fa172ffe69e40cd7d15d5c66

开始编译源码

# 获取iStore提供的FEEDS
cd istoreos
wget https://fw0.koolcenter.com/iStoreOS/h88k/feeds.conf

# 以后每次编译前建议执行以下三行命令更新源码
git pull
./scripts/feeds update -a
./scripts/feeds install -a

# 下载iStore官方的H88K编译配置文件
wget -O .config https://fw0.koolcenter.com/iStoreOS/h88k/config.buildinfo

# 开始编译
make menuconfig		# 进入固件配置界面
make download V=s -j8	# 下载所需源码，请尽量使用梯子
make V=s -j$(nproc)	# 首次编译推荐用单线程

# 清理相关
make clean		# 在源码有大规模更新或者内核更新后执行，以保证编译质量，此操作会删除/bin和/build_dir目录中的文件
make dirclean		# 更换架构编译前必须执行，此操作相当于 make clean 以及删除/staging_dir、/toolchain、/tmp和/logs中的文件
make distclean		# 除非打算 push 到远程仓库 否则几乎用不到，此操作相当于 make dirclean 外加删除/dl、/feeds目录和.config文件

其他杂项内容

关于制作补丁

# 建议在git clone后立即修改制作，因为后续feeds的更新和安装会带来大量变动
cd istoreos
git status					# 查看当前的状态
git add (file|dir)				# 添加文件或目录
git diff istoreos-22.03				# 查看当前的改动
git diff istoreos-22.03 > ../xxx.patch		# 将改动作成补丁


# 在新克隆的源码中使用制作的补丁
git apply --stat ../xxx.patch			# 检查补丁的格式
git apply --check ../xxx.patch			# 测试补丁能否应用到当前分支
git apply xxx.patch				# 应用此补丁到当前分支

# 如果 git apply 时遇到 trailing whitespace 问题，可加入 --whitespace=fix 选项
# git apply --whitespace=fix ../xxx.patch

制作出来的补丁部分内容样式如下
