[Xenomai-help] pcibios_find_device

[Ramon]

Hi,

I'm porting an old practice environment in RTLinux to Xenomai.

In that code I use commands like "pcibios_find_device" to obtain the 
addresses used by a PCI AD/DA board
(we access to this device at a register level  using outb commands).

In the old rtlinux environment my code was executed in kernel mode and I 
could access "pcibios_...."  commands easily. Is it possible
to use these commands in user space mode (using xenomai) ?

Thank you
Ramon

Not directly, but you may use libpci:

Note however that you may run into other issues if you intend to use
hardware directly in user-space. It is probably a better idea to use
RTDM to write a driver in kernel-space.
