2019-05-14scripts/gdb: silence pep8 checksStephen Boyd1-0/+1
These scripts have some pep8 style warnings. Fix them up so that this directory is all pep8 clean.

2016-05-23scripts/gdb: cast CPU numbers to integerJan Kiszka1-1/+1
We won't see more than 2 billion CPUs any time soon, and having cpu_list return long makes the output of lx-cpus a bit ugly.

2016-05-23scripts/gdb: add cpu iteratorsKieran Bingham1-0/+38
The linux kernel provides macro's for iterating against values from the cpu_list masks. By providing some commonly used masks, we can mirror the kernels helper macros with easy to use generators.

2015-02-17scripts/gdb: port to python3 / gdb7.7Pantelis Koukousoulas1-1/+4
I tried to use these scripts in an ubuntu 14.04 host (gdb 7.7 compiled against python 3.3) but there were several errors. I believe this patch fixes these issues so that the commands now work (I tested lx-symbols, lx-dmesg, lx-lsmod). Main issues that needed to be resolved: * In python 2 iterators have a "next()" method. In python 3 it is __next__() instead (so let's just add both). * In older python versions there was an implicit conversion in object.__format__() (used when an object is in string.format()) where it was converting the object to str first and then calling str's __format__(). This has now been removed so we must explicitly convert to str the objects for which we need to keep this behavior. * In dmesg.py: in python 3 log_buf is now a "memoryview" object which needs to be converted to a string in order to use string methods like "splitlines()". Luckily memoryview exists in python 2.7.6 as well, so we can convert log_buf to memoryview and use the same code in both python 2 and python 3. This version of the patch has now been tested with gdb 7.7 and both python 3.4 and python 2.7.6 (I think asking for at least python 2.7.6 is a reasonable requirement instead of complicating the code with version checks etc).

2015-02-17scripts/gdb: add class to iterate over CPU masksJan Kiszka1-0/+54
Will be used first to count module references. It is optimized to read the mask only once per stop.

2015-02-17scripts/gdb: add lx_current convenience functionJan Kiszka1-0/+17
This is a shorthand for *$lx_per_cpu("current_task"), i.e. a convenience function to retrieve the currently running task of the active context.

2015-02-17scripts/gdb: add internal helper and convenience function for per-cpu lookupJan Kiszka1-0/+68
This function allows to obtain a per-cpu variable, either of the current or an explicitly specified CPU. Note: sparc64 version is untested. Signed-off-by: Jan Kiszka <[email protected]> Cc: "David S.
