Subject: FPU emulator unsafe for SMP?
Date: Thu, 14 Feb 2002 17:56:31 -0800 [thread overview]
Message-ID: <3C6C6ACF.CAD2FFC@mvista.com> (raw)
I have been chasing a FPU register corruption problem on a SMP box. The
curruption seems to be caused by FPU emulator code. Is that code SMP safe?
If not, what are the volunerable spots?
Just thought I'd check before I dive into it ....
BTW, I think even with the latest fpu emu patch, the classic fpu/signal
problem is still there. I will post in a separate email later.
