Re: [Xenomai-core] x86 FPU switches routines.

I tested it on my laptop without drivers using FPU, and it appears to work correctly, but it would be nice if people that had problems with the previous attempt (if I remember correctly, on old pentiums and on AMD processors) could test this patch. Ok, nobody has complained so far, it works for me too on a few test boxen, so I'm going to merge this patch for 2.3-rc2. So please everybody, let's give this hell _now_ on as many x86 boxen as we can, checking out the trunk, so that we won't reiterate the 2.2.3 mess. -- Philippe. ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core

Just fired up on a Pentium MMX which used to have problems with the first approad. Switchtest reports no problems. What about writing a simple test case for the non-RT in-kernel FPU usage?

I plan to add it to the switchtest driver, but I wanted to make sure that the new support already works in the usual case. -- Gilles Chanteperdrix ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
