| 2024-07-22 | kernel: explicitly store process RIP and RFLAGS | dzwdz | |
| Once again, needed for the interrupt return syscall. Seems to have made the kernel slower in timebench? | |||
| 2024-07-22 | kernel: use IRET instead of SYSRET for switching into usermode | dzwdz | |
| I want to implement a new syscall for returning from "interrupts" (my crappy take on Plan 9's notes / UNIX signals), and I've realized that I can't use SYSRET for that, as it clobbers RCX and R11. This hasn't been an issue so far, as I've only been switching into usermode to return from syscalls, but now I might be switching into it at arbitrary moments (right after an interrupt handler recovers from a page fault, etc). I could make it so I switch between IRET and SYSRET depending on the context, but I don't think it's worth it. | |||
