There are also 1 GiB pages in long mode, but support depends on the processor and CPUID's output. Almost all modern x86 processors in the last several years should have it, I think.
- monocasa 3y agoSome also technically support it, but it doesn't gain you a whole lot as the TLB will split it down to a 2MB TLB entry. Could save a bit of L2 for the page table entries under the right conditions, but you've already lost if invoking your page walk hardware is in your fast path to begin with.
