Compile Linux kernel module without Module.symvers

I have this embedded Linux devices. I would like to add kernel-level functionality to it, but would highly prefer not to compile my own kernel to do so. (If the kernel doesn't load and get to user space the device is bricked; I can't access the bootloader to recover it. The current kernel doesn't have kexec support so I couldn't use that to test a kernel image of my own.)



The device's kernel has support for modules, but I do not have a copy of the corresponding Module.symvers file.



My question: if I do not have the Module.symvers file for a Linux kernel but do have the kernel image and a module compiled for it, can I compile more modules that can be inserted into that kernel, maybe by generating the missing Module.symvers file?

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
