Hi,
I would like to use floating point arithmetics (double, ..) and operations
(sin, cos) inside a rtdm task.
How should I do this ?
You should not.
If you really want to, you have two solutions:
- let the kernel compile your module as is, this will generated
soft-float
Hi,
I'm trying to port some old stuff from RTLinuxfree. As a first step I would
like to recompile
and check everything. Latter I will try to modify the code structure to fit
xenomai structure.

Hi
There are some differences with RTLinuxfree which are making things
difficult ... .
One last question (offtopic ?¿)
In user space I can use outb commands (using ioperm). For example :
#define PORT_PARALLEL 0x378
outb(valor,PORT_PARALLEL);
This can
application, but you
may want to consider it.

One of the drivers that I am creating requires OMAP3 Neon processing
(hard SIMD floating point). In a standard Linux environment the Neon
code would be executed in the driver's back end
