Cubieboard2 移植到最新内核 Linux 3.11+ 与ARM VIRTUALIZATION

cini

Cubieboard2 移植到最新内核 Linux 3.11+。1号拿到 Cubieboard2 板子， 5号移植成功DTS，7号移植成功EMAC，昨天基本搞到SMP，system_counter还有问题，争取这两天搞定后会提交patch，搞定后主要想在ARM A7上实现ARM VIRTUALIZATION，以前写了片VIRTUALIZATION文章：http://hi.baidu.com/cinifr/item/02dd23d5526d4c3ce3108f86 有同好的可以联系QQ：113074954.

BOOT 3.11+ on Cubieboard2:
EMAC + SMP + arch_timer OK 不过使用arch_timer BogoMIPS不知道为什么不准确，貌似OMAP5使用ARCH_timer也有这个问题，明天希望能修复这个问题。当前Cubieboard2 kernel 运行在secure PL1的最高权限，呵呵可以尝试我的tiny hypervisor。
这个礼拜争取提交一个完整的patch到社区。

[PATCH ] ARM: sunxi: Add Emac,SMP and Arch_timer support for sunxi A20;Add phy cnt arch timer for ARMv7 support.
It has been tested on a Cubieboard 2. To use SMP you must set ARM_ARCH_TIMER and ARM_ARCH_TIMER_USE_PHYCNT when make xconfig.
If you have any questions or comments please feel free to contact me.  Have a wonderful day!
移植最新的kernel 3.11+  到cubieboard2
1得到最新的主流kernel：
git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
2打上我的patch：
patch -p1 < ../linux-next/add_smp_emac_archtimer_forA20.patch
patch -p1 < ../linux-next/add_phy_archtimer.patch
3用我的CubieBoard2_config代替.config
cp CubieBoard2_config .config
4编译kernel
make zImage  ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- -j4
5编译DTS
make dtbs ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- -j4
6boot  kernel
新的kernel需要DTS来启动：
在uboot输入如下命令 需要tftp支持，tftp 0x48000000 uImage;tftp 0x42000000 sun7i-a20-cubieboard2.dtb;bootm 0x48000000 - 0x42000000
注意：bootm 后的第3个参数非常重要 它记录的是DTS的地址。
问题：目前3.11 kernel还不支持CB2 display，MMC等。希望以后有时间能搞定。

给力，等会回去在我的mele a100上试试楼主的patch。

这里太冷清，而且我给的patch不全，几个新加的文件没有包括 我建议你直接加arm mail kernel list ：http://lists.infradead.org/mailman/listinfo/linux-arm-kernel 老外对这个比较热心， 而且以后的patch都会发在哪儿。

DreamDreams

mailing list还是不方便追踪，为嘛不在github上维护的repo呢，有兴趣的就去pull，免得得自己翻mailing list.

bigfish

大哥，请教你下，看了你 CB2最新3.12内核的文章，我按照做了，但是没法启动，我是 TF卡方式启动的
已经放了 u-boot 、spl/sunxi-spl.bin script.bin uEnv.txt

但是一直没有搞明白  DTBS要怎么设定，能详细告诉我一下么，是不是修改 boot.cmd 文件呢？


        setenv bootargs console=ttyS0,115200 noinitrd init=/init root=/dev/mmcblk0p2 rootfstype=ext4 rootwait panic=10 ${extra}
        fatload mmc 0 0x43000000 script.bin
        fatload mmc 0 0x48000000 uImage
        bootm 0x48000000

要怎么改才能启动呢，？，还是要自己移植DTD？？

bigfish

最新的内核是 3.12的， LZ能指点下，需要做哪些步骤呢？， 我好像启动的是单核，而且CPU的频率也不对，是不是要移植 arch/arm/mach_sun7i相关的东西呢？
