How to get hexagon-npu log?

[finneyyan]

I run gdbserver success, but can't enter hexagon function, and my message from printf-function is neither in terminal nor in logcat.
The native print function is DEVICE_LOG_INFO/WARN/ERROR. How should I get the message from them?

Heyhey

• For the sources inside npu/device, its running directly at hexagon npu's rtos, will redirect the log to logcat
• For the npu/host, can capture the log from console since we're reusing ggml's log print function

When I debug npu_device_support_op, an op return false however none logcat display but E llama-cli: vendor/qcom/proprietary/adsprpc/src/fastrpc_apps_user.c:1495: Error 0x27: remote_handle64_invoke failed for handle 0xb400007e7fdb8e90, method 3 on domain 3 (sc 0x3020100) (errno Success)

Thanks for reply. Yes I can get npu/host log. What's the tag of npu/device logcat?

No worries folk,

• [profiler] -- for profiler output
• adsprpc or cdsprpcd -- this for DEVICE_LOG_INFO/WARN/ERROR

@chraac Sorry to bother you again. I still cannot get locat with adsprpc or cdsprpcd tag, even if I modify as:

#if defined(__ANDROID__)
#include <android/log.h>
#define DEVICE_LOG_ERROR(...) __android_log_print(ANDROID_LOG_ERROR, "NPU", __VA_ARGS__)
#define DEVICE_LOG_WARN(...)  __android_log_print(ANDROID_LOG_WARN, "NPU", __VA_ARGS__)
#define DEVICE_LOG_INFO(...)  __android_log_print(ANDROID_LOG_INFO, "NPU", __VA_ARGS__)
#else
#define DEVICE_LOG_ERROR(...) FARF(FATAL, __VA_ARGS__)
#define DEVICE_LOG_WARN(...)  FARF(ERROR, __VA_ARGS__)
#define DEVICE_LOG_INFO(...)  FARF(HIGH, __VA_ARGS__)
#endif

Instead, I can read something like these: (every time I run npu_device_device_support_op and return not success)

Does this mean that there is something wrong with my rpc system so no log output?

forgot to said, had to enable the FARF logcat output first, for test-backend-ops, can do something like:

adb shell "echo 0x1f > /data/local/tmp/test-backend-ops.farf"

then we can get the output from logcat
