From Chapter 5 of the book The design of Unix operating system by Bach, an algorithm to create an (unnamed) pipe is given. It states that,



assign an inode from pipe device (algorithm ialloc)



A pipe device is just a file system designated for pipe device from which kernel can assign inodes and data blocks to the pipes.



I want to know more about this pipe device specific file system. Can anyone suggest where to look for it?

  • Ok, the book is from 1986, if I googled correctly. Are you interested in the implementation details in the context of 30+ year old book; or in details on how things work in practice on more-or-less current systems; or in how things work in the abstract based on (current or historical) standards and customs?

The sources for the file system in question are here:



https://sourceforge.net/p/schillix-on/schillix-on/ci/default/tree/usr/src/uts/common/fs/fifofs/



also have a look at this man page:



http://schillix.sourceforge.net/man/man3c/fattach.3c.html



fattach() allows to mount a FIFO based object on top of a 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...
