Why is it so much like this? The circular buffer size is limited, the kernel may write something into it at any time, so this process is normal. After each read, the circular buffer is considered to have been processed (that is, it turns into invalid content), so it is normal for you to read it empty again. Each time you read a file, kmsg is actually a circular buffer inside the kernel. You can use the dmesg tool or the klogd daemon to retrieve these messages. You can also use the system to call syslog To retrieve these messages.
At any time, only one Super User-authorized process can read the file. Open it and check the msm_kgsl field.ĭescription: used to retrieve kernel messages generated by printk. For example, ADB shell dumpsys meminfo system is used to view the memory information of the process of the system.ĪDB shell CAT/proc/kmsg> kmsg.txt. The ADB shell dumpsys command contains all the content about the system service. The bread contains dmesg, dumpstate, and dumpsys.ĭumpstate is the system status information, which is comprehensive, including the current memory information, CPU information, logcat cache, and kernel cache of the mobile phone. (For the log Capturing Method of qxdm, see the basic usage instructions and functions of qpst and qxdm)īugreport (command ADB bugreport> bugreport. All the solutions provided by Qualcomm can be grasped. It's rich in content, such as RF, telephone, and Internet access.
Of course, if it is not a Qualcomm chip, you don't need to mention it. Whether it is Android or not, as long as the Qualcomm chip is used, it will be very familiar with it. The last is the qxdm of the Qualcomm platform. pcap, such as the UA profile during MMS download, the APN download Using proxy when browser is surfing the internet, and the streaming-related content including UA profile. ADB shell tcpdump-s 10000-W/sdcard/capture. Tcpdump is very useful and can be used for TCP/IP protocols. Sim STK will also be in it, modem-related atcommand and so on, of course, it is far from qxdm.ĪDB logcat-B events-V time prints logs of system events, such as touch-screen events. Log print Application LogĪDB logcat-B radio-V time> radio. The status information includes ADB shell CAT/proc/kmsg, ADB shell dmesg, ADB shell dumpstate, ADB shell dumpsys, ADB bugreport, and project mode.ĪDB logcat-B Main-V time> app. Real-time printing mainly involves logcat main, logcat radio, logcat events, tcpdump, and qxdm logs on the Qualcomm platform.
