Madhu K <madhu.sk89@xxxxxxxxx> · Mon, 8 Aug 2016 14:41:06 +0530

Hi Saket Sinha,

I am also kernel newbie, I started Eucalyptula challenge challenge 4 months back, till now I have completed 4 tasks and submitted result for 5th task two months back, till now I have not received any response from little.

So during this time I wanted occupy with other kernel stuff, can please share how to proceed with "TODOs in the staging area drive" you mentioned below.It will be more helpful for me and other newbies to involve in kernel development activity.

Thanks&regards,
Madhu

Hi All,

I am new to this list. Please help me with any new bie helper guide.

How do we get work assigned here? or this is just a query forum.

Regards,

Anurag

Hi Anurag,

Welcome to the list. This is a query forum but we can surely help you with

getting started.

Take up Eucalyptus challenge or the TODOs in the staging area driver if

you're interested in kernel development.

Let me know if you're looking for something specific.

Regards,

Saket Sinha

I think you're talking about eudyptula [1], unfortunayelly, it seems that little

has been out of business for quite a while now.

@Anurag: welcome here :)

Heh... it's called the eudyptula challenge, not the eucalyptus challenge. Also,

please don't top-post.

A: Because this is annoying

Q: Why?

Subject: Linux Coding style template

I want to transform some C source files. following Linux kernel coding style.

- Does script/Lindent STRICTLY follows all linux kernel coding style rules?

- What scripts/templates do you use/suggest for elegant code style

with the fact that

  we are talking about Linux Kernel Coding?

The GNU guys suggest indent with the following parameters:

-nbad -bap -nbc -bbo -hnl -br -brs -c33 -cd33 -ncdb -ce -ci4

-cli0 -d0 -di1 -nfc1 -i8 -ip0 -l80 -lp -npcs -nprs -npsl -sai

-saf -saw -ncs -nsc -sob -nfca -cp33 -ss -ts8 -il1

On the other hand:

Linux/script/Lindent contains:

-npro -kr -i8 -ts8 -sob -l80 -ss -ncs -cp1

Differences so far:

1)

indent with gnu parameters inserts a space on labels eg.

 err: vs

err:

2)

indent with gnu parameters inserts 26 spaces

#endif                                                        /*

something like this*/

So probably gnu site is outdated?

Also, I have noticed  that they both fail theyto leave the empty line

of a label empty

For example, err: code

to

err:

       code

What does the coding style suggests in this case?

Have you found, other cases such the above?

Probably, start with running Lindent, and then fix up the mess it leaves

by hand.  Shouldn't take more than a day to do it.

good luck!

My questions are more generic, i am interesting in an automatic way for

identation! And also, i am interesting to what kernel developers will

do in the following cases,  so i am  forwarding again the email.

please take a look to this example

width is 90, what a kernel developer will do? spliti in two lines, or

leave it us it is,

cause i think it's more readable, in this way

qq->run = mmap(NULL, mmap_size, PROT_READ | PROT_WRITE, MAP_SHARED,

qq->vcpu, 0);

Also, have you find a way to tell indent not to indent, struct definitions?

In .h, when you have a huge structure definition, it's more readable,

to have it's struct friend one below the other, aligned!

struct kvm_mem_bank {

          struct list_head           list;

         u64                              guest_phys_addr;

         void                              *host_addr;

        u64                               size;

};

This also counts for variables initiliazation

int x = 0

char  *dog         = animal->dog->name;

char  *cat          = animal->cat->name;

char * elephant = animal->elephant->name;

Any ideas?

- Does script/Lindent STRICTLY follows all linux kernel coding style rules?

- What scripts/templates do you use/suggest for elegant code style
