今天写好device,成功编译出CM,接下来肯定是调戏啦(你什么都没看到)~
BUG肯定也是一堆堆的!一开机,果然一堆error~可是尼玛,大蛋一放假就不见人了!!!
我自己折腾几个小时容易么我,我谷歌了几个小时容易么我ヽ(｀д´)ﾉ

上面就是错误信息啦,一眼看过去就看出了pmem驱动无法打开
What,为神马打不开啊???因为文件不存在啊,魂淡!
然后我就把kernel的config给提取出来看了下
$ adb pull /proc/config.gz 245 KB/s (20151 bytes in 0.080s) $ gunzip -c config.gz |grep PMEM CONFIG_ANDROID_PMEM=y
次奥,内核都开启了PMEM为神马还是不行啊!!!(つД`)
好吧,接着我就去看dmesg,看看到底是神马回事...
<6>[ 2.445319] loop: module loaded <1>[ 2.447678] pmem: pmem_setup: unable to register pmem driver(pmem) - zero size passed in! <4>[ 2.455961] android_pmem: probe of android_pmem.0 failed with error -1 <1>[ 2.462321] pmem: pmem_setup: unable to register pmem driver(pmem_adsp) - zero size passed in! <4>[ 2.471003] android_pmem: probe of android_pmem.1 failed with error -1 <1>[ 2.477379] pmem: pmem_setup: unable to register pmem driver(pmem_audio) - zero size passed in! <4>[ 2.486199] android_pmem: probe of android_pmem.2 failed with error -1
好吧,pmem都起不来了,怪不得找不到驱动...
个人感觉那货需要从内核源码搞了,但是没有源码啊,肿么破???
那俺就只好用ION取代PMEM了,pougai!!!!
打开device/{manufacturer}/{device}/BoardConfig.mk,添加下面的代码
# Uses ION memory manager,Renounce the use of PMEM TARGET_USES_ION := true
然后重新编译,你也可以用mmm单独编译模块~
刷进手机,重启,看log!!欧耶,这个BUG没有了,但是剩下的BUG还有一堆堆...
