Pretend Linux Drive to Access Windows Driver

All Windows Hardware will be tough to accomplish. Some
pretty near goals of the project is to add Graphics and
Sound handling, obvoiusly support of Graphics means mouse
support as well... Other hardware, such as serial, or USB
support (other than that which can be done using coFS -
coLinux's Host FileSystem) is probably a lot futher off.

but isn't "UNIX meta data mode" for cofs more usage? (better
compatible with cygwin)
gui/sound is fun but not too much, as we're already in
Windows GUI. and it's why you use colinux "on windows",
not a native linux windows

I'm a little late on writing this I know, I just don't feel like write
alot again and again to try disribe my idea to you and still
have you confused. I just not good at discrbing thing Sorry.
People not understanding me is what tippically happen when
i ask for a feature request.

Please note I use cappital to highlight below I'm not Yelling.

From my prev. replys
>>>"but isn't "UNIX meta data mode" for cofs more usage?"
>>> (better compatible with cygwin)

what is "UNIX meta data mode" ? can you please give me a
link to more info. and what dose cygwin have anything to do
with colinux drivers. I useing colinux because I hate cygwin
and there stupid install system.

>>>>All Windows Hardware will be tough to accomplish.

Can you please Tell me why. I would realy like to here why
be a bit micro scopic programer my self.

I thought mouse support was part of directX as well as
windows video in case you do get what i say I try to say it
again in a different way.

When you run Colinux.exe
Is there away to send windows api call from inside the
running linux system?

I know with UML(user mode linux) it can detect itself runig on
another linux system so I imagin you can do it with colinux
but detect it running a windows system. I'm thinking Buy
patching the Kernel you might be able to said them WIN API
FUCTION CALL but I never look at the kernel source to know
and probbly never will becuase it far above my head.

If this could be done I would imagin Linux drive for
mouse,keyboad,Joystick ect would be easy to make just
have it use the directX API.

I know this might sound far fetch, and May be blow way out
of poportion. I know notthing about the kernel or the write
drivers for linux system. That the reson i had to check buy
write this feature reqest. I Thought with someone with the
proper knowage this might be an easy task and would like to
know if it was not.

It will be a new mode for cofs, similar to the way cygwin does.
It will allow symlinks and user/group/other permissions,
special files like in /dev, etc, like in a real linux system.

The final objective would be to allow colinux to mount a
windows directory and boot from it.

Now the thruth is that it isn't implemented it yet, but it's
in the idea beyond cofs.

CoLinux kernel runs in Ring 0, but it can't touch the
hardware or the probable outcome is a computer crash
(because windows thinks it's the only one using the hardware
directly).

Implementing a generic virtual hardware layer that "talks"
to windows is something that falls into a true
virtualization scheme, most probably affecting the colinux
performance (and a very hard work to acomplish).

No. CoLinux kernel and user programs think they are in a
native linux system (and have no way of knowing it isn't true) .

CoLinux kernel runs in Ring 0, and no way to directly call
any windows function. All it can do is send a message to the
colinux windows kernel driver and request it to call some
function for him (but that involves a context switch from
linux mode to windows mode).

You don't need any DirectX to use the keyboard & mouse.
Basic Win32 API is enough. And remember DirectX is a COM
interface. You can't use it in kernel mode.

Thank alot Nuno Lucas for your reply,even though i still have
a little hard time under standing it, it help me out a lot. It
dose tell me i got to look into more detail of the cofs(wich
would probbly help me understand things a bit better). I
thought that cof was just to access your hard drive in colinux.
But if i understand what you wrote you are work on it to make
it do more than that.
