A cli tool to install a hardware breakpoint/watchpoint on a process in linux. This is useful for debugging a process without having to attach a debugger to it.

Now it supports x86_64 and arm64. You can use it on rooted Android devices as well.

pwatch <pid> <type> <addr>
pwatch -t <tid> <type> <addr>

For example:

pwatch 31737 rw4 0x55fa689a90

This will install a read/write 4 byte watchpoint on the address 0x55fa689a90 of all threads in the process with pid 31737.
