[Crash-utility] gcore extension source code

[Dreyfus, Thirtsa (Mobileye)]

Hi,

Thanks, Found it.

So question about this extension:
I'm trying to create a process core from a vmcore.
As result I get a correct elf core. But I see that one note, called .note.linuxcore.file is missing.
I implemented there a code to dump this note.
But now, I realized that there is a filter option, so tried "gcore -f 255", But I get this failure: 
gcore: read error: physical address: 7cb8f3800000000  type: "page table"

I'd want to understand first if this filter can help me for dumping this specific note. Because if not - I won't investigate there, and will use my code.
Does someone know?

 Thanks,
Tirtsah.

I think crash-gcore-command-1.5.1.tar.gz in the crash extension modules page [1] is the latest released gcore source code.  As written in the page, Hatayama-san is the maintainer of it.
