一、获取可能死锁的进程相关的数据
adb root
adb shell debuggerd -b (pid)
adb shell cat /sys/kernel/debug/binder/proc/(pid)
adb shell ps -T -p (pid)如果遇到找不到文件，类似报错如下
canoe:/ # cat /sys/kernel/debug/binder/proc/1020
cat: /sys/kernel/debug/binder/proc/1020: No such file or directory
就可以尝试挂载debugfs
mount -t debugfs debugfs /sys/kernel/debug
ls /sys/kernel/debug/binder
ls /sys/kernel/debug/binder/proc下面是一个正常进程的数据
canoe:/ # ps -T -p 1020

----- end 1020 -----二、解析示例：如何解读获得的正常数据
线程状态
thread 1020: l 00 need_return 0 tr 0
thread 1024: l 12 need_return 0 tr 0
thread 1026: l 11 need_return 0 tr 0
thread 1028: l 00 need_return 0 tr 0
thread 5981: l 11 need_return 0 tr 0结合前面的 ps -T -p 1020：
1024 / 1026 / 5981是 binder 线程，WCHAN=binder_th+1020 / 1025 / 1027 / 1028多数在ep_poll1531在futex_wait
这通常表示：
binder:1020_x这些 binder 线程大概率处于空闲待命或轻度工作状态，不像被事务压满。tr 0很关键，表示这个线程当前没有挂着活跃 transaction 栈。need_return 0也正常，说明没有卡在一个必须立刻回 binder driver 的异常状态。
l 11、l 12 是 binder looper 状态位，精确位含义不用过度纠结。实战里主要看两点：
- 它是不是 binder looper 线程
- 它有没有 transaction / todo / pending work
这份里看不出"线程被事务拖死"。
proc级别状态
proc 1020
context binder这表示它在默认 binder 上下文，不是 hwbinder 或 vndbinder。这本身正常。
如果一个进程被 binder 请求压住，常见会在这个文件里看到更多类似这些痕迹：
todo队列transaction列表pending async- 某个 thread 下挂着 transaction 详情
- 大量
from <pid>:<tid> to 1020:<tid>的记录
这份正常的数据没有这些内容，这是最重要的观察点。
node行怎么理解
node 98: ...
node 94: ...
node 343: ...
node 337: ...这些 node 是"这个进程暴露出去的 Binder 对象"。可以粗略理解成"这个服务进程提供了哪些 Binder endpoint"。
后面的字段里：
hs/hw：强/弱引用相关状态ls/lw：本地引用计数is/iw：内部引用计数proc ...：有哪些进程持有或关联这个 node
这些字段在日常排障里通常不是第一优先级。这里几个 node 的引用数量都不夸张，看不出异常膨胀。
ref行怎么理解
ref 88: desc 0 node 1 ...
ref 327: desc 1 node 287 ...
ref 12536: desc 2 node 12535 ...
ref 16100: desc 3 node 16099 ...这些 ref 表示"1020 这个进程持有的远端 Binder 句柄"。也就是它作为客户端连了哪些别的 Binder 服务。
同样，这些值本身不说明阻塞。除非你看到非常异常的增长，或者明确知道某个句柄正对应故障链上的服务。
这份输出能得出的结论
这份是正常机上的快照，从 binder 角度看更像：
- binder 线程池存在，至少有 3 个 binder worker 线程。
- 这些 binder 线程在抓取瞬间没有明显忙死。
- 没看到事务堆积、pending async、todo backlog。
- 没看到某个线程正在执行或卡住 transaction。
所以，这份输出更适合作为正常基线 。它说明"一个健康的 carwatchdogd/binder 服务，在 binder/proc/<pid> 里大概长这样"。
和故障机该怎么对比
如果问题机真的是 binder backlog 或 carwatchdogd 被压死，故障时抓出来通常会比这个多出明显异常信号，例如：
- 某些 binder 线程下面挂着 transaction 详情，长时间不变。
- 出现大量 async transaction 记录。
- 出现
proc todo或 thread todo 不断积压。 - 所有 binder 线程都不在
binder_thread_read空闲态，而是都挂在 transaction 上。 - 某个发送方 PID 反复出现，持续往同一个 node 打请求。
在故障机上，尽量在"system_server 已经卡住但还没被杀"的窗口里，连续抓 3 份：
cat /sys/kernel/debug/binder/proc/1173
ps -T -p 1173
debuggerd -b 1173最好每隔 1 到 2 秒抓一次，连续抓 3 次。分析时看这三个问题：
- binder/proc/1173 里有没有 transaction backlog 或 async pending。
- ps -T -p 1173 里 binder 线程是不是全部不再空闲。
- debuggerd -b 1173 里线程到底卡在 binder driver、锁等待，还是 carwatchdogd 自己的业务逻辑里。
三、解析示例：如何解读获得得异常数据
下面是debuggerd抓取的调用栈，同样的调用栈抓取了3次。由于发生了死锁，3份文件的调用栈都在同样的地方。

它是 C++ 标准库 std::shared_mutex 的底层实现名（libc++ 里的内部类名）。
简单说就是"读写锁"：
lock()：申请写锁（独占）
lock_shared()：申请读锁（共享）
上面的堆栈也能对应上源码，例如1184线程的堆栈对应/packages/services/Car/cpp/watchdog/server/src/WatchdogServiceHelper.h中
bool isServiceConnected() {
std::shared_lock readLock(mRWMutex);
return mService != nullptr;
}结合代码，整理出死锁的发生原理
5997线程
WatchdogInternalHandler::registerCarWatchdogService
→ WatchdogServiceHelper::registerService（拿 WatchdogServiceHelper.mRWMutex 写锁）
→ WatchdogProcessService::registerCarWatchdogService
→ WatchdogProcessService::registerClient
→ PackageInfoResolver::asyncFetchPackageNamesForUids（想拿 PackageInfoResolver.mRWMutex 读锁，阻塞）
1184线程
WatchdogPerfService::handleMessage
→ WatchdogPerfService::processCollectionEvent
→ UidStatsCollector::collect
→ PackageInfoResolver::getPackageInfosForUids
→ PackageInfoResolver::updatePackageInfos（拿 PackageInfoResolver.mRWMutex 写锁）
→ WatchdogServiceHelper::isServiceConnected（想拿 WatchdogServiceHelper.mRWMutex 读锁，阻塞）简而言之：A线程先拿了1号锁，之后申请2号锁；B线程先拿了2号锁，之后申请1号锁。2个线程拿着各自的锁，等待另一个锁，于是发生死锁。
解决方案：为了求稳，这里我只改了PackageInfoResolver::asyncFetchPackageNamesForUids。其实最好把另一个线程中调用的PackageInfoResolver::updatePackageInfos也改改，避免持有一个锁的时候又去申请另一个锁的情况。不过，这里又涉及到updatePackageInfos()这个函数的原子性和其中成员变量的异步问题，在此就不展开了。
仅就此次发现的死锁问题而言，改PackageInfoResolver::asyncFetchPackageNamesForUids已经可以解决。
修改代码示例如下：
void PackageInfoResolver::asyncFetchPackageNamesForUids(
const std::vector<uid_t>& uids,
const std::function<void(std::unordered_map<uid_t, std::string>)>& callback) {
// 注释掉原生的锁
// std::shared_lock writeLock(mRWMutex);
// mPendingPackageNames.push_back(std::make_pair(uids, callback));
// 对vector单独使用新的锁mPendingPackageNamesMutex，保障vector的线程安全
// 其它使用mPendingPackageNames和定义它的地方也要修改上锁，这里就不给出代码了
{
std::lock_guard<std::mutex> lock(mPendingPackageNamesMutex);
mPendingPackageNames.push_back(std::make_pair(uids, callback));
}
mHandlerLooper->removeMessages(mMessageHandler, MSG_RESOLVE_PACKAGE_NAME);
mHandlerLooper->sendMessage(mMessageHandler, Message(MSG_RESOLVE_PACKAGE_NAME));
}这是安卓16上发现的一个原生carwatchdogd死锁问题，且发现安卓15上的代码也一样存在这种死锁的可能。但安卓14的代码差异较大，不存在这个问题。
这个死锁的概率应该是比较低的，需要两个线程正好持锁互相等待。目前在谷歌的git上并没发现对应的修改patch。
