9b7e48c6bd Kernel: Replace raw asm functions with naked ones 2021-07-05 16:40:00 +02:00

8c14488106 Kernel: Get rid of of some of the duplicate kernel base address macros 2021-07-05 12:28:45 +02:00

040fe0054b Kernel: Merge the x86 and x86_64 boot code into a single file 
They're mostly the same apart from some x86_64-specific parts.

458ac9bbba Kernel/x86_64: Halt if we happen to boot on non-x86_64 machine 2021-07-03 18:40:37 +02:00

db334b50d0 Kernel: Don't byteswap the ISR number on interrupt entry 
Let's just add the padding before we jump to interrupt_common_asm_entry.

e37576440d Kernel: Fix stack alignment on x86_64 
These were already properly aligned (as far as I can tell).

50839bd1f1 Kernel: Properly initialize r8-r15 for new threads on x86_64 2021-06-30 15:13:30 +02:00

e979a88af4 Kernel: Implement do_assume_context for execve() on x86_64 2021-06-28 22:29:28 +02:00

a8587fbfb9 Kernel: Use FlatPtr for register-sized values 2021-06-28 22:29:28 +02:00

b5aad1c81d Kernel: Fix GDT and segment selectors to make userland work on x86_64 
Userland faulted on the very first instruction before because the
PML4T/PDPT/etc. weren't marked as user-accessible. For some reason
x86 doesn't care about that.

Also, we need to provide an appropriate userspace stack segment
selector to iretq.

32840dfa17 Kernel: Implement more x86_64 context switching functionality 2021-06-28 15:55:00 +02:00

076692b1ef Kernel: Implement entry code for x86_64 interrupts 
With this fixed we can now properly handle interrupts (e.g. timer
interrupts) on x86_64.

328d44e227 Kernel: Fix stack for new threads on x86_64 
Unlike on x86 iretq always pops rsp and ss.

9ed051fe25 Kernel: Implement initializing threads on x86_64 2021-06-27 15:46:42 +02:00

f285241cb8 Kernel: Rename Thread::tss to Thread::regs and add x86_64 support 
We're using software context switches so calling this struct tss is
somewhat misleading.

df530941cc Kernel: Implement safe_* memory access functions for x86_64 2021-06-27 15:46:42 +02:00

79ab9cce18 Kernel: Clear segment registers on x86_64 
They're supposedly unused but iretq doesn't like ss being non-zero.

19c0498ccc Kernel: Update the x86_64 boot code to match i386's code 2021-06-25 15:19:09 +02:00

38fca26f54 Kernel: Add stubs for missing x86_64 functionality 
This adds just enough stubs to make the kernel compile on x86_64. Obviously
it won't do anything useful - in fact it won't even attempt to boot because
Multiboot doesn't support ELF64 binaries - but it gets those compiler errors
out of the way so more progress can be made getting all the missing
functionality in place.

62f9377656 Kernel: Move special sections into Sections.h 
This also removes a lot of CPU.h includes infavor for Sections.h
