在aarch64上编译，fstack: master分支：5b97230c858598a10e1b82c tag: v1.23, origin/master
F-Stack一个基于DPDK的开源和高性能网络框架
基于DPDK23.11需要做如下操作
sed替换：
sed -n '/DEV_RX_OFFLOAD_IPV4_CKSUM/p' drivers/net/macb/*
sed -i 's/ETH_/RTE_ETH_/g' *.c
sed -i 's/DEV_/RTE_ETH_/g' *.c
f-stack适配dpdk20.11
sed -i 's/RTE_MBUF_F_RX_IP_CKSUM_BAD/PKT_RX_IP_CKSUM_BAD/g' *.c
sed -i 's/RTE_MBUF_F_/PKT_/g' *.c
注释掉： pmap_change_prot
编译错误：call-clobbered register used for global register variable
文件freebsd/arm64/include/pcpu.h中x18改为x22
register struct pcpu *pcpup __asm ("x22");
这样改虽然通过编译，但一直有段错误：freebsd/net/netisr.c:1139，所以改为非寄存器变量
f-stack/lib/include/machine/pcpu.h:50:40: error: ‘struct pcpu’ has no member named ‘pc_prvspace修改如下:
-#define PCPU_SET(member,value) (pcpup->pc_ ## member = (value))
+#define PCPU_SET(member,value) (pcpup = (value))
编译错误ffs重定义

基于dpdk20.11， f-stack master分支：5b97230c858598a10e1b82c tag: v1.23, origin/master，修改如下，可以正常编译
编译redis错误：jemalloc/jemalloc.h: No such file or directory
jemalloc重载了Linux下的ANSIC的malloc和free函数，解决方法如下：
在make命令后加上参数malloc
make MALLOC=libc
编译f-stack lib导出：
export FF_PATH=/root/f-stack
export PKG_CONFIG_PATH=/usr/lib64/pkgconfig:/usr/local/lib64/pkgconfig:/usr/lib/pkgconfig
nginx with debug
./configure --prefix=/usr/local/nginx_fstack --with-ff_module --with-cc-opt=" -g3 "
./helloworld --conf /etc/f-stack.conf --proc-type=primary
struct pcpu *
# Close ASLR; it is necessary in multiple process
echo 0 > /proc/sys/kernel/randomize_va_space
uma_startup1
在aarch64平台，struct pcpu没有成员 pc_prvspace，修改如下：
+++ b/freebsd/arm64/include/pcpu.h
+ struct pcpu *pc_prvspace; \
u_int pc_bcast_tlbi_workaround; \
u_int pc_mpidr; /* stored MPIDR value */ \
- char __pad[201]
+ char __pad[197]
下面是用fstack自带的dpdk21.11的arch64补丁包：
编译错误：./machine_include/machine/pcpu.h:60:23: error: call-clobbered register used for global register variable [-Werror]
60 | register struct pcpu *pcpup __asm ("x18");
| ^~~~~
加上：-ffixed-x18，选项可以解决上面的问题
解压：f-stack_head.tar，拷其中的文件到下面目录，拷
cp -f ff_config.h /usr/local/include/ff_config.h
cp -f ff_api.h /usr/local/include/ff_api.h
cp -f ff_event.h /usr/local/include/ff_event.h
cp -f ff_errno.h /usr/local/include/ff_errno.h
cp -f ff_epoll.h /usr/local/include/ff_epoll.h
库文件操作如下：
cp -f libfstack.a /usr/local/lib/libfstack.a.1.23
ln -sf /usr/local/lib/libfstack.a.1.23 /usr/local/lib/libfstack.a
