D | pat.txt | 2 PAT (Page Attribute Table) 4 x86 Page Attribute Table (PAT) allows for setting the memory attribute at the 5 page level granularity. PAT is complementary to the MTRR settings which allows 6 for setting of memory types over physical address ranges. However, PAT is 13 PAT allows for different types of memory attributes. The most commonly used 18 PAT APIs 100 With PAT support, a new API pgprot_writecombine is being added. So, drivers can 112 MTRR effects on PAT / non-PAT systems 116 using ioremap*() calls on x86 for both non-PAT and PAT systems. Ideally 118 be a no-op on PAT enabled systems.
