But disassembling pud_offset shows different values.ĭump of assembler code for function pud_offset:Ġxffffffff812bfc4a : and rax,QWORD PTR # 0xffffffff826e8fc0 Ġxffffffff812bfc51 : shr rsi,0x1b # : pop rbpĠxffffffff812bfc56 : and rax,0xfffffffffffff000Ġxffffffff812bfc5c : and esi,0xff8 # : add rax,QWORD PTR # 0xffffffff826d1f48 So we have exactly one level of indirection. Discúlpeme por los engaños y las artimañas.

I apologize for the indirection and trickery. Es una tabla de indirección que reproyecta todos los bloques en el volumen. The problem: According to the pud_index source code I expected it to be compiled with the shift right by 0x1e ( PUD_SHIFT) and then anded with 0x1ff ( PTRS_PER_PUD - 1). It is an indirection table that remaps all the blocks on the volume. Return (address > PUD_SHIFT) & (PTRS_PER_PUD - 1) Pud_index: static inline unsigned long pud_index(unsigned long address) Return (pud_t *)_va(p4d_val(p4d) & p4d_pfn_mask(p4d)) Let’s understand the formula through an example. P4d_pgtable: static inline pud_t *p4d_pgtable(p4d_t p4d) Return p4d_pgtable(*p4d) + pud_index(address) īoth p4d_pgtable and pud_index calls were inlined in the resulting assembly (below). Source code: static inline pud_t *pud_offset(p4d_t *p4d, unsigned long address) But encountered difference between source code and it's disassemble. I'm using 4 levels page table (LA57 disabled) and tried to understand the implementation of getting virtual address of the 3rd level page.
