一、insmod 遇到签名问题：
Required key not available
key文件路径：out/target/product/msm8953_64/obj/kernel/msm-3.18
sign-file路径：kernel/msm-3.18/scripts
模块路径：out/target/product/msm8953_64/obj/kernel/msm-3.18/driver
举例如下：
perl /kernel/msm-3.18/scripts/sign-file sha512 signing_key.priv signing_key.x509 ~/asix.ko
二、开机自动加载模块
diff --git a/qcom/msm8953_64/init.target.rc b/qcom/msm8953_64/init.target.rc
index c6caf93..0f14ef9 100755
--- a/qcom/msm8953_64/init.target.rc
+++ b/qcom/msm8953_64/init.target.rc
@@ -164,6 +164,8 @@ on boot

# access permission for secure touch

三、增加selinux权限
type=1400 audit(15.489:5): avc: denied { module_load } for pid=1 comm="init" path="/system/lib/modules/asix.ko" dev="mmcblk0p24" ino=2289 scontext=u:r:init:s0 tcontext=u:object_r:system_file:s0 tclass=system permissive=0
开机过程需要增加selinux权限
allow secontext tcontext:class 许可 ;
secontext指的是scontext=u:r:init:s0的init，tcontext 指的是 tcontext=u:object_r:system_file:s0 中的system_file， class指的是“tclass=system”中的system，许可指的是“denied { module_load }”中的module_load，
