Hi For linux on x86 platform, we have 4 level paging i.e. PGD, PUD,PMD and PTE (according to UTLK) or atleast PGD , PMD and PTE. Now there is something called global descriptor table (GDT) and local descriptor table (LDT). What is the relationship between these two things? What is the relationship between GDT and PGD if any?
Nothing. GDT and LDT on x86 are arrays of segment descriptors. The segment registers (CS/DS etc) are actually index into this array. This has nothing to do with page table entries / directories.
