Micro SD died middle of a pacman update. How do I reboot it remotely (have a SSH session active)? I think that might solve the problem.



I have a Raspberry Pi 3 running Arch Linux ARM aarch64.



Anything involving sudo won't work because:




/usr/bin/sudo: Input/output error





linux

  • Try the reboot command but I think you're hosed without sudo.

  • If sudo isn't working in this manner then there's little chance that anything else will work either.

  • There's sysrq reboot, but that requires root: linuxjournal.com/content/rebooting-magic-way

    If the SD is hosed, the chance it boots well are slim.

  • Remove power, replace SD card, attach power.

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...
