H A D | pat.rst | 4 PAT (Page Attribute Table) 7 x86 Page Attribute Table (PAT) allows for setting the memory attribute at the 8 page level granularity. PAT is complementary to the MTRR settings which allows 9 for setting of memory types over physical address ranges. However, PAT is 16 PAT allows for different types of memory attributes. The most commonly used 28 PAT APIs 108 With PAT support, a new API pgprot_writecombine is being added. So, drivers can 120 MTRR effects on PAT / non-PAT systems 124 using ioremap*() calls on x86 for both non-PAT and PAT systems. Ideally 126 be a no-op on PAT enabled systems.
