QUESTION
I'm extending a program which take arguments of traced function and print it. Everything works fine with numeric arguments and short strings. But it's not clear how to handle with long string that longer than stack size in eBPF (which is limited with 512 byte).
In example below, string is limited by 80 bytes, of course it can be increased up to 512, but how to track more longer strings?
Example of C program with traced function which called "ameba"

Answered 2018-Dec-06 at 17:32I read about BPF_MAP_TYPE_PERCPU_ARRAY could help in such case, but it's not clear for me how to use it.
You're right. Peeps usually rely on per-cpu arrays to overcome stack size limitations. The following implements that sort of solution, whereby I'm using a per-cpu array to store struct ameba_event_t
instead of storing it on the stack.
I think you're going to need Linux v4.18 to be able to do this (you need commit d71962f). I haven't tested the code as I don't have the right setup at hand, but can later if you run into any issue.
QUESTION
I'm playing with gobpf and have got an issue with calculating a duration of traced user-space function. I use bpf_ktime_get_ns() to read time and then trying to calculate delta, but got enormous numbers, though traced function sleeps just 1 second.
Here is the tested C-program, which has a function called "ameba".

Answered 2018-Nov-18 at 08:37This looks like it is caused by a mismatch of paddings between kernel and user sides. The data_t
structure is actually padded at compile-time to be equivalent to the following:
QUESTION
I am currently working on FreeRTOS v8.1.2 on Realtek Ameba board and I am using IAR Embedded Workbench IDE.
I am facing a weird issue with xTimerIsTimerActive()
API of FreeRTOS.
I have a periodic timer and for this periodic timer the xTimerIsTimerActive()
is always returning True even if I am explicitly stopping and deleting the timer by calling xTimerStop()
and xTimerDelete()
actually the code is written in a repeating manner.
But xTimerIsTimerActive()
also returns True even if the timer is not created and timer handle is initialized NULL.
Sorry I cannot post the code here because it's properitory.
...ANSWER
Answered 2017-Apr-07 at 14:41You can only call API functions on valid options. If you call xTimerIsTimerActive() on a software timer that has been deleted the object is no longer valid and the behviour undetermined.

Install ameba
You can use ameba like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the ameba component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
