grehan 2005-11-11 02:06:54 UTC FreeBSD src repository Modified files: (Branch: RELENG_6) sys/powerpc/powerpc pmap.c Log: MFC r1.102 > Finally (!?) get to the bottom of the mysterious G3 boot-time panics. > After a number of tests using nop's to change the alignment, it was > confirmed that the mtibat instructions should be cache-aligned. > FreeScale app note AN2540 indicates that the isync before and after > the mtdbat is the right thing to do, but sync/isync isn't required > before the mtibat so it has been removed. > > Fix by using a ".balign 32" to pull the code in question to the correct > alignment.
