Booting MX28-EVK without bootloader support

2012-06-07 Thread Subodh Nijsure



I am using git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git 
for-next branch to get familiar with device tree.


I am following procedure described in following thread --

http://lists.ozlabs.org/pipermail/devicetree-discuss/2012-April/014600.html

Turn on CONFIG_ARM_APPENDED_DTB,  CONFIG_ARM_ARAG_DTB, then appending 
imx28-evk.dtb and constructing zImage_dtb


However this image never initializes network interfaces, I can't mount 
nfs as rootfs. Is the appended DTB supposed to work from above 
referenced git repo & branch?


Is there a device-tree newbies mailing list by any chance?

Re: How can I disable all USB devices?

2012-06-07 Thread 夏业添

Sorry for reply so late. I'm an intern and I cannot test your
suggestion in the past two days. I didn't fully understand this udev
stuff and your reply, and here is my questions:

a. about ":="
  The man page says that the ":=" means that "Assign a value to a key
finally; disallow any later changes, which may be used to prevent
changes by any later rules."
  So I think a rule like this:

  SUBSYSTEMS=="usb", ACTION=="add", RUN:="/test.sh usb"

will prevent adding more programs to RUN, and finally stop calling any
"modprobe" in /lib/udev/rules.d/80-drivers.rules so that drivers are
not loaded. But the usb devices are still working.

b. The function of steps 2
My environment is a costumed Linux, I cannot find
/lib/modules/$(uname -r) directory...

c. how to identify the device is a usb device.
Just seeing the examples on
http://www.reactivated.net/writing_udev_rules.html, I'm more confused.
Each usb device has a particular match keys. I just want to know
whether this device is connecting to usb ports, and manage it.

If anybody has some hints, please tell me. Thanks!

How to understand super.c/descriptor_loc for ext2/ext3/ext4?

2012-06-07 Thread Ryan Wang

Hi,

I'm reading the source code for ext2/ext3/ext4, and cannot figure
out how descriptor_loc() runs:

1600static ext3_fsblk_t descriptor_loc(struct super_block *sb,
1601ext3_fsblk_t logic_sb_block,
1602int nr)
1603{
1604struct ext3_sb_info *sbi = EXT3_SB(sb);
1605unsigned long bg, first_meta_bg;
1606int has_super = 0;
1607
1608first_meta_bg = le32_to_cpu(sbi->s_es->s_first_meta_bg);


1) Who can setup the field ->s_first_meta_bg, mke2fs? And what does it mean?
   What's a meta block group?

1609
1610if (!EXT3_HAS_INCOMPAT_FEATURE(sb,
EXT3_FEATURE_INCOMPAT_META_BG) ||
1611nr < first_meta_bg)

2) In which case, we can have "nr < first_meta_bg"?
   And how does EXT3_FEATURE_INCOMPAT_META_BG affect the physical disk
layout?


1612return (logic_sb_block + nr + 1);
1613bg = sbi->s_desc_per_block * nr;
1614if (ext3_bg_has_super(sb, bg))
1615has_super = 1;
1616return (has_super + ext3_group_first_block_no(sb, bg));

3) It always return the first block no of the specific bg, right?
   Then its caller ext3_fill_super will read in the disk block.
   It seems that ext3_fill_super just read many copies of one same block
   (1st block), right?

   I'm sure I'm wrong with it, but cannot find out the right way.

1617}


Any explanation are welcome.

Thanks! I'll try it now.

I've made changes to your code, so it "probably" will:
 - Run on 3.4 Kernel
 - Partially meet Kernel coding style (Try to run scripts/checkpatch.pl -f m.c)
 - Stop working due lack of locking at m_ioctl(). I'm working on this now... :-)

How to understand super.c/descriptor_loc for ext2/ext3/ext4?

out how descriptor_loc() runs:

1600 static

descriptor_loc (struct
super_block  *sb

first_meta_bg  =

1) Who can setup the field ->s_first_meta_bg, mke2fs? And what does it mean?
   What's a meta block group?

There is no .ioctl at struct file_operations...

ok, then start with that. But, do understand the normal kernel changes
betwwen ur kernel source and current one.

 Harishkumar,

 I already know my SoC name, it is Celestial CSM1203, and it is not
 available in any official kernel source tree ( the last one I checked it
 3.4.1 10 minutes ago).

 Since it is not available in the original kernel source, we had to make
 those thousands of changes one-by-one, and it would take years, right?

 Am I correct?

 Dear Harishkumar;

 Thank you very much for your quick answer.

 Where can I find related Celestial SoC & driver patch file?

 Sertac,

 Basically u need to have Celestial SoC & drivers related patch.
 Then, u can download desired kernel or latest 3.3.x.

 Apply and do the forward porting. It won't be straight forward, u need
 to re-write a bit.
 U can always refer any other celectial SoC family in latest kernel
 source or other ARM9 family.

  Starting point will be, arch/arm.
  make platform base CPU SoC code and serial up.
  If u able to make these things up, then its addition of pheripherals.

Since it is not available in the original kernel source, we had to make

Sertac,

Basically u need to have Celestial SoC & drivers related patch.
Then, u can download desired kernel or latest 3.3.x.

Apply and do the forward porting. It won't be straight forward, u 
need to re-write a bit.
U can always refer any other celectial SoC family in latest kernel 
source or other ARM9 family.

 Dear All;

 I have a digital satellite receiver (named Chipbox), which uses linux
 kernel 2.6.12.5.

 Main chipset name is Celestial CSM1203 ( It is ARM926EJ-S core).

 The original kernel source (and all other sources) can be downloaded
 here: http://www.merihvideo.com.tr/chipbox-source.php

 I would like to add some functionality (Such as CIFS, USB WIFI...) to
 my STB. In order to do that, I need to cross compile new kernel.

 However, the chipset provider ( Celestial) does not provide a new
 kernel to do this. They just compiled 2.6.12.5 for about 5-6 years ago, and
 they didn't do a new kernel from that time.

 So, I need your helps:

 1) Celestial has done a lot of modifications on the original 2.6.12.5
 source ( drivers, headers, definitions...) All these changes can be seen by
 using MELD tool.

 2) In order to have a new kernel ( Such as 2.6.35.13) which can be
 running on my chipbox, what are the steps should be done one by one?

 Can you please explain for a newbie please?

 Best Regards

 Sertac

Re: New kernel for Chipbox

2012-06-07 Thread Sertac TULLUK

Dear Harishkumar;

I already know how to find the changes, please see my 1st e-mail below.

The problem is, those changes are more than thousands of lines of code, and 
hundreds of files are added or modified.

I wonder, how can I apply those thousands of changes to new kernel source 
quickly and easily?

After that, I will cross compile new kernel, and everything will be fine. But 
how to apply those thousands of changes? How long it would take?

Do we need to change Kconfig files? Do I need to change Makefiles? or both?

New kernel for Chipbox

2012-06-07 Thread Sertac TULLUK

Dear All;

I have a digital satellite receiver (named Chipbox), which uses linux kernel 
2.6.12.5.

Main chipset name is Celestial CSM1203 ( It is ARM926EJ-S core).

The original kernel source (and all other sources) can be downloaded here: 
http://www.merihvideo.com.tr/chipbox-source.php

I would like to add some functionality (Such as CIFS, USB WIFI...) to my STB. 
In order to do that, I need to cross compile new kernel.

However, the chipset provider ( Celestial) does not provide a new kernel to do 
this. They just compiled 2.6.12.5 for about 5-6 years ago, and they didn't do a 
new kernel from that time.

So, I need your helps:

1) Celestial has done a lot of modifications on the original 2.6.12.5 source ( 
drivers, headers, definitions...) All these changes can be seen by using MELD 
tool.

2) In order to have a new kernel ( Such as 2.6.35.13) which can be running on 
my chipbox, what are the steps should be done one by one?

Can you please explain for a newbie please?

Best Regards
