Unable to find any information about TLB on my computer or obtain information about hardware counters about TLB

The Ubuntu version I am using is **Ubuntu 18.04.6 LTS**, and the kernel version is **5.4.0-148 generic**. My processor is **12th Gen Intel (R) Core (TM) i7-12700**. I would like to know the number of TLB entries in my CPU for different page sizes (1G, 2MB, 4KB), as well as the number of dTLB misses during program execution.

-1

command told me they are 0： L1 TLB/cache information: 2M/4M pages & L1 TLB (0x80000005/eax): instruction # entries = 0x0 (0) instruction associativity = 0x0 (0) data # entries = 0x0 (0) data associativity = 0x0 (0) L1 TLB/cache information: 4K pages & L1 TLB (0x80000005/ebx): instruction # entries = 0x0 (0) instruction associativity = 0x0 (0) data # entries = 0x0 (0) data associativity = 0x0 (0) L1 data cache information (0x80000005/ecx): line size (bytes) = 0x0 (0) lines per tag = 0x0 (0) associativity = 0x0 (0) size (KB) = 0x0 (0) L1 instruction cache information (0x80000005/edx): line size (bytes) = 0x0 (0) lines per tag = 0x0 (0) associativity = 0x0 (0) size (KB) = 0x0 (0) L2 TLB/cache information: 2M/4M pages & L2 TLB (0x80000006/eax): instruction # entries = 0x0 (0) instruction associativity = L2 off (0) data # entries = 0x0 (0) data associativity = L2 off (0) L2 TLB/cache information: 4K pages & L2 TLB (0x80000006/ebx): instruction # entries = 0x0 (0) instruction associativity = L2 off (0) data # entries = 0x0 (0) data associativity = L2 off (0) L2 unified cache information (0x80000006/ecx): line size (bytes) = 0x40 (64) lines per tag = 0x0 (0) associativity = 0x7 (7) size (KB) = 0x500 (1280) L3 cache information (0x80000006/edx): line size (bytes) = 0x0 (0) lines per tag = 0x0 (0) associativity = L2 off (0) size (in 512KB units) = 0x0 (0)
