No it is accessing system memory by DMA to transfer frames. Since the system has 128MB ram, the addresses are probably all in the first 128MB range. I tried changing cyrix.c to explicitly set the serialize bit (0x8000 in PCR0) rather than explcitly clearing it as is done now. Didn't make a difference. I tried reversing the memory bypass setting, which also did nothing. Enabling CONFIG_X86_OOSTORE and recompiling however does make a difference. > --- arch/i386/Kconfig.cpu~ 2007-02-05 03:44:54.000000000 +0900 > +++ arch/i386/Kconfig.cpu 2007-02-17 21:25:52.000000000 +0900 > @@ -322,7 +322,7 @@ config X86_USE_3DNOW > > config X86_OOSTORE > bool > - depends on (MWINCHIP3D || MWINCHIP2 || MWINCHIPC6) && MTRR > + depends on (MWINCHIP3D || MWINCHIP2 || MWINCHIPC6) && MTRR || MGEODEGX1 > default y > > config X86_TSC I did: depends on ((MWINCHIP3D || MWINCHIP2 || MWINCHIPC6) && MTRR) || MGEODEGX1 since I wasn't sure of the precedence in the Kconfig files. -- Len Sorensen
