That would have been easy had I used my self-compiled kernel - but it seems there is no debuginfo file available for the Arch Linux supplied kernels, which I ran in this case. So I can only provide a disassembled listing of that function, with offset 0x76 aka +118 inside: Dump of assembler code for function amdgpu_vm_cpu_set_ptes: 0x0000000000027c80 <+0>: callq 0x27c85 <amdgpu_vm_cpu_set_ptes+5> 0x0000000000027c85 <+5>: push %r15 0x0000000000027c87 <+7>: mov %rcx,%r15 0x0000000000027c8a <+10>: push %r14 0x0000000000027c8c <+12>: mov %rdi,%r14 0x0000000000027c8f <+15>: mov %rsi,%rdi 0x0000000000027c92 <+18>: push %r13 0x0000000000027c94 <+20>: mov %r8d,%r13d 0x0000000000027c97 <+23>: push %r12 0x0000000000027c99 <+25>: mov %rdx,%r12 0x0000000000027c9c <+28>: push %rbp 0x0000000000027c9d <+29>: mov %r9d,%ebp 0x0000000000027ca0 <+32>: push %rbx 0x0000000000027ca1 <+33>: callq 0x27ca6 <amdgpu_vm_cpu_set_ptes+38> 0x0000000000027ca6 <+38>: add %rax,%r12 0x0000000000027ca9 <+41>: nopl 0x0(%rax,%rax,1) 0x0000000000027cae <+46>: xor %ebx,%ebx 0x0000000000027cb0 <+48>: test %r13d,%r13d 0x0000000000027cb3 <+51>: je 0x27cfb <amdgpu_vm_cpu_set_ptes+123> 0x0000000000027cb5 <+53>: mov 0x28(%r14),%rax 0x0000000000027cb9 <+57>: mov %r15,%rcx 0x0000000000027cbc <+60>: test %rax,%rax 0x0000000000027cbf <+63>: je 0x27cd3 <amdgpu_vm_cpu_set_ptes+83> 0x0000000000027cc1 <+65>: mov %r15,%rdx 0x0000000000027cc4 <+68>: mov $0xfffffffffffff000,%rcx 0x0000000000027ccb <+75>: shr $0xc,%rdx 0x0000000000027ccf <+79>: and (%rax,%rdx,8),%rcx 0x0000000000027cd3 <+83>: mov (%r14),%rdi 0x0000000000027cd6 <+86>: mov %ebx,%edx 0x0000000000027cd8 <+88>: add $0x1,%ebx 0x0000000000027cdb <+91>: mov 0x38(%rsp),%r8 0x0000000000027ce0 <+96>: mov %r12,%rsi 0x0000000000027ce3 <+99>: add %rbp,%r15 0x0000000000027ce6 <+102>: mov 0x968(%rdi),%rax 0x0000000000027ced <+109>: mov 0x18(%rax),%rax 0x0000000000027cf1 <+113>: callq 0x27cf6 <amdgpu_vm_cpu_set_ptes+118> 0x0000000000027cf6 <+118>: cmp %ebx,%r13d 0x0000000000027cf9 <+121>: jne 0x27cb5 <amdgpu_vm_cpu_set_ptes+53> 0x0000000000027cfb <+123>: pop %rbx 0x0000000000027cfc <+124>: pop %rbp 0x0000000000027cfd <+125>: pop %r12 0x0000000000027cff <+127>: pop %r13 0x0000000000027d01 <+129>: pop %r14 0x0000000000027d03 <+131>: pop %r15 0x0000000000027d05 <+133>: retq 0x0000000000027d06 <+134>: mov %gs:0x0(%rip),%eax # 0x27d0d <amdgpu_vm_cpu_set_ptes+141> 0x0000000000027d0d <+141>: mov %eax,%eax 0x0000000000027d0f <+143>: bt %rax,0x0(%rip) # 0x27d17 <amdgpu_vm_cpu_set_ptes+151> 0x0000000000027d17 <+151>: jae 0x27cae <amdgpu_vm_cpu_set_ptes+46> 0x0000000000027d19 <+153>: incl %gs:0x0(%rip) # 0x27d20 <amdgpu_vm_cpu_set_ptes+160> 0x0000000000027d20 <+160>: mov 0x0(%rip),%rbx # 0x27d27 <amdgpu_vm_cpu_set_ptes+167> 0x0000000000027d27 <+167>: test %rbx,%rbx 0x0000000000027d2a <+170>: je 0x27d55 <amdgpu_vm_cpu_set_ptes+213> 0x0000000000027d2c <+172>: mov (%rbx),%rax 0x0000000000027d2f <+175>: mov 0x8(%rbx),%rdi 0x0000000000027d33 <+179>: add $0x18,%rbx 0x0000000000027d37 <+183>: mov 0x38(%rsp),%r9 0x0000000000027d3c <+188>: mov %ebp,%r8d 0x0000000000027d3f <+191>: mov %r13d,%ecx 0x0000000000027d42 <+194>: mov %r15,%rdx 0x0000000000027d45 <+197>: mov %r12,%rsi 0x0000000000027d48 <+200>: callq 0x27d4d <amdgpu_vm_cpu_set_ptes+205> 0x0000000000027d4d <+205>: mov (%rbx),%rax 0x0000000000027d50 <+208>: test %rax,%rax 0x0000000000027d53 <+211>: jne 0x27d2f <amdgpu_vm_cpu_set_ptes+175> 0x0000000000027d55 <+213>: decl %gs:0x0(%rip) # 0x27d5c <amdgpu_vm_cpu_set_ptes+220> 0x0000000000027d5c <+220>: jne 0x27cae <amdgpu_vm_cpu_set_ptes+46> 0x0000000000027d62 <+226>: callq 0x27d67 <amdgpu_vm_cpu_set_ptes+231> 0x0000000000027d67 <+231>: jmpq 0x27cae <amdgpu_vm_cpu_set_ptes+46>
