How to make a kernel modules in petalinux

i am making a kernel module in petalinux with QEMU(emulator).
I mean, my computer's OS is ubuntu. And then I turn on the QEMU, and next I turn on the petalinux.
My problem is that I can't make a kernel module with SDK or Makefile.
First of all, when I make a module with SDK, I don't understand the Manual.
I think manual is for board.
Second, when I make a module with Makefile, module was generated.
But when I download the module in petalinux.
There is error which is 'invalid module format' message.
Third, There is module in linux, and I want to run this module in petalinux.
Is it possible??
If there is a solution, how can i run that module.
I have no idea about them.
I want to solve the problem as soon as possible.
If you have any ideas, please let me know. Thank you.

Hi,
Try placing the module in /kernel/drv/sparcv9 or /usr/kernel/drv/
sparcv9 and give it a try.
On more research..
man page of modload(1M) says that,
If filename is an absolute pathname then the file specified
by that absolute path is loaded. If filename does not begin
with a '/' then the path to load filename is relative to
the current directory unless the -p option is specified.
The kernel's modpath variable can be set using the
/etc/system file. The default value of the kernel's modpath
variable is set to the path where the operating system was
loaded. Typically this is /kernel /usr/kernel.
Thanks,
Gopinath.

How to compile a kernel module without recompiling the whole kernel?

Hi,
I'm pretty sure my question is a bit newbish, still I haven't been able to found any information/solution to my problem in 3days.
The kernel I use doesn't come with the module I need for my hardware and I would like to know if there's a way to compile it without having to make a new kernel myself (since compiling the kernel takes ages on my machine).
Even if your answer is a "Let me Google that for you", I'm so desperate that I'll be happy to see it.
Thank you all in advance for your answers!

Do you have a /proc/config.gz that you could use? Otherwise I don't know. I mean, many modules should be compilable simply with the system-installed kernel headers, but not all native modules might follow that rule.
Unfortunatel most of what you find on the web talks about how to create new modules which can be compild against the installed kernel tree, not about how to compile one of the native kernel modules against it.
Actually, try what those links suggest.
Skip the configuration part, and just do:
make -C /lib/modules/`uname -r`/build M=$(PWD)/drivers/video modules
(maybe `make -C /lib/modules/`uname -r`/build M=$(PWD)/drivers/video clean` first )
EDIT: Meh, that uses your config and won't build that driver... there must be some way though
EDIT2: Try:
make -C /lib/modules/`uname -r`/build M=$(PWD)/drivers/video modules CONFIG_FB_VT8623=m CONFIG_FB_SVGALIB=m
The problem though is, that they might have removed some of the dependencies of the module, so if it doesn't compile, you'll have to recompile the kernel.
Good thing is though, you can use their .config as base (found in /usr/src/linux-..../.config)
You can also check if your config "supports" your module by putting it into the kernel source tree, running `make menuconfig` and typing /8623 and pressing enter.
The last line in that screen should read:
Selects: <list of options>
As long as all of those options are either =y or =m, you're good. SVGALIB can be =n because it's part of drivers/video/ and you can compile it together with your module.

How to use Corecrypto kernel module

Hi all,
I know that Corecrypto kernel module received a FIPS 140 vaulidation, but I can't find any document for this module.
My questions is: how can I leverge this crypto module? For example, is there any API exposed so that I can use it to do AES encryption?
Is it a replacement of CommonCrypto library, or totally different thing?

It's an Apple internal one; They're slowly but surely moving stuff out of xnu and into kexts - corecrypto is one example, and pthread.kext is another (formerly all those psync functions). It's a totally different thing.
in the xnu's src - 2422, /libkern/libkern/crypto/register_crypto.h, you have the crypto_functions struct. This relies on the EXTERNAL_HEADERS/corecrypto headers, but that's about all the documentation you're going to get in the form of the function prototypes it registers (albeit for internal use). Other functionality in the kernel (most notably CoreStorage, and AppleKeyStore iOS has nke.tls, SEP, the dreaded AMFI, and others) then calls these functions, and visible exported one e.g. xts_encrypt (libkern/crypto/corecrypto_aesxts.c) call on the cc.kext. I doubt Apple will let you release a kext which ties to corecrypto.kext, since the latter is deemed private.
CommonCrypto is still very much alive, but that's the user mode API. That's /usr/lib/system/libcorecrypto.dylib, which is re-exported by LibSystem (like the rest of the .../system/ dylibs). That's safe to use (again, in user mode).
It's possible that at some point they'll create a UserClient so that libcorecrypto would actually go via IOKit to kernel mode and do the crypto there, but that's not how it is now. To parallel Linux, it also has a crypto directory in the kernel sources, which are used for kernel-mode sym encryption/hashes, but you still have a user mode libcrypt (part of openSSL) which takes no advantage of that.

How to communicate wite kernel module

After a kernel module was loaded successfully, how to communicate wite this kernel module like change the status of the kernel module.
In Linux, I can use /proc file to do that. But, In solaris, /proc file is just used for processors.
Now, how can I communicate write my kernel module? Can I use /proc file to do that like in Linux?

Hello,
<ul>
<li>forget /proc, the procfs is for process table only on solaris
<li>if the kernel module is "driver" type you can use standard read/write/ioctl ... on block/charcter in dev (see OpenSolaris community and documentation Writing Device Drivers)
<li>there are other types of kernel modules such as streams, filesystems, schedulers ...
<li>the kernel module can export some symbols to see it from mdb (see blog)
<li>...
</ul>

How to make two Application Modules share the same entity cache?

Hello everyone, I am using JDeveloper 11.1.2.3.0
I have a little problem in my application through using two AppModules that contain also same ViewObjects. So to be clear one VO is declared in two AppModules. When I commit the view by using AppModule1 and then go to another page that uses the same VO but from AppModule2, I have to commit again, even through the row is previously stored in the database.
I understood that this came because different AppModules use different entityCache for database communications.
I am asking if anyone knows any option on how to sync the entity caches from the two appmodules, or how to make them use the same entity cache.
Thank you

You can make a copy of the app and give it another name, but it will use the same settings files no matter which you open. Settings aren't stored in the app, but in your Preferences.
Firefox, being a Windows derivative, might have the capability to use "Profiles" where you'd set it up different for each profile. I don't use Firefox, so I don't know if that option exists.

How to write a kernel module for Solaris

Hi
I would like to know where I can find information about writing a kernel module for Solaris. Is there a pdf developers reference?

http://docs.sun.com
Search "writing device drivers".Even if I don't intend writing a device driver?

How to begin a kernel module?

Hello,
I am new to solaris OS. Now I want to write a kernel module, which may be a simple (pseudo )file system. I have read some materials, such as "Writing a device driver" provided by docs.sun.com and "Slaris Internals", , but I have no idea to start. I wonder if ddi and dki functions are enough to implement a simple file system. Could someone please give me some guides for achieve my goal? Thank you !!!

Hello.
There are different kernel modules:
- Drivers
- streams modules
- misc. modules
- file systems and
- executable file formats
(I think there are even more types)
As far as I know only drivers and streams modules are documented. (Misc. modules are not documented but they are quite simple.)
As far as I know file system modules are not documented but I think the necessary DDI functions are present in the sys/include files of Solaris.
If your pseudo file system driver does not access anything which requires kernel access you might write an NFS file server that runs in user mode instead and mount your file system using "-F NFS". I think this is only a bit more difficult than writing a real file system driver. Note that the NFS protocol is well documented!

How to write a Kernel Modules ?

Hi Everybody,
I'm trying to write a kernel module for the solaris 7 (64 bit) kernel.
but i can't modload it.
should i put it in a specific directory or can i modload it from my home
directory ?
maybe i'm not using the right compilation switches ? what should they be
can anyone send me a redundant module ( such as the one in the _init man
page) that actually downloads ?
thanx
Oren
p.s. please send your response to [email protected]

How to make this function module as RFC to get data from different system?

Hi
I am trying to use following function module . This function module is used to copy data from one cube to another cube within same system however I need a this should happen across two different system. How can I use this function module to make it remote call to different system and do the same function what it is doing ?
Name of function module -
RSDRT_INFOCUBE_DATA_COPY
Any help would be really helpful
AG

HI,
let us say you want to copy the data of a cube in system A to a cube in system B .
1) create a RFC function module in system B (in this function module call the function module RSDRI_CUBE_WRITE_PACKAGE to update the data), this RFC function module should have same parametersa as RSDRI_CUBE_WRITE_PACKAGE .
2) write a program in system A .. read the data from the infocube using the function module RSDRI_INFOPROV_READ and call the RFC function module in system B that you have created..
for the details of the parameters to pass to these two function modules use the RSDRT_INFOCUBE_DATA_COPY and get the required code
Thanks

How to make site search module work?

Hi guys
I am working on a sample site http://webmar.businesscatalyst.com/index.
I had insert a site search module but anyhow when i search for any query and click the Go button, it will go the searchresult page but nothing get displayed.
I do had placed a {module_searchresults} in the page content area of searchresult page.
How I populate by search result page?
Thanks
Andy

Andy make sure you index (re-index)your site
Modules > Site Search > Re- Index button
If site is a sample site ( demo mode ) I am not sure if it will index with new changes to the way demo sites works. Give it a try it may be ok internally, but wont index with S E unless live site
Good to re-index if made changes or added content

How to make a news module?

Hello,
I'd like to add a news module to the website I'm making and I've really got no clue about how to do this... so if anyone could point me in the right direction, that'd be great!
What I'd like is:
A news column on my Home page. The news would appear with a time stamp and the content would be truncated.
Example:
2009-06-11: User group meeting in London
The annual group meeting this year was held in...
2009-04-09: New model release
The version 4.2 of the software AAA is...
The user could click on each news on the Home page and be redirected to the full article, hosted on the News page. All recent articles would be listed there, with full content, images, etc.
Ideally, in order to keep the News page to a decent size, "old" news would "automatically" be moved somewhere else, either another page (News Archives) or something else (?).
So far, I only know (a bit of) HTML and CSS, the rest is still a total mystery to me.
I'd be grateful for any comment on this!

Communication between Loadable Kernel Modules

Hi,
Anybody know how can I make my kernel modules to communicate with each other. For example, module A needs to call a function in module B. If it is possible, will there be any differences in 32 and 64 bits architecture?
Thanks

The following methods may be able to be used.
You can get device information, dev_info structure, by DEVI macro which defined sys/ddi_impldefs.h .
The dev_info structure has parent and child dev_info structure by linked-list.
And any dev_info has own "dip" in "ddi_minor_data" structure.
If you set private data with "dip" by using ddi_xxx_driver_private(dip) function, you may be able to communicate with another driver module.
Please teach me the right method ;-)

How to inform the kernel about newly installed STREAMS MODULE?

I made a copy of timod and installed the copy to /kernel/strmod
as a new module (newmod). I modified the t_open.c to make
it to use the "newmod" instead of the timod. The result of the
test is "Invalid Argument". It looks like the kernel doesn't
recognize the module "newmod". I looked throught Sun
Docs, I'm not able to find any instruction for how to
make kernel to recognize my new STREAMS module name
as the add_drv does for device drivers. Can anyone point
me to the right docs and give me some instructions for informing
the kernel about the newly installed STREAMS module?
Thanks
Yuen

Forget my precedent post, here is what's on the configuration page of this module :
("[_]" are checkboxe)
1/ [_] Check this option if your users' DNs look like cn=jdoe,ou=Group1,cn=example,cn=com and Group1 turns out to be the group you want.)
Attribute of the DN which contains the group name:
[Single line text field to enter attribute]
(The name of the attribute which contains the group name. In the example above, it would be ou, as the DN contains the string ou=Group1 and Group1 happens to be the desired group name.
2/ [_] Groups are specified by LDAP attributes
Attribute names (one per line):
[Multi-lines text field]
(If the groups are stored in the user entries, along with the rest of their data, then enter here a list of attributes which may contain them.)
3/ [_] Groups exist as LDAP entries where a multivalued attribute contains the members' CNs
Nodes containing groups (one per line):
[Multi-lines text field]
(Enter here a list of nodes from where groups should be searched for. The module will look them up recursively from the given nodes.)
Attribute holding group members:
[Single line text field]
(Name of the multivalued attribute which holds the CNs of group members, for example: memberUid)
If someone could tell me which checkboxe I should select and what to put into fields it would be king as I really have no idea of what to enter and what to select.

How to make use out of Kernel Reader Software Rules??

Each of my agents have a Kernel Reader module loaded but there are only two software rules defined (rknrd105 & rknrd106). There are many other software rules available but I don't know how to make use out of them. How do I add them to the module?? Please assist.
Thanks in advance.
