2024-02-24	arch: i386: cleanup everything and reorganize	Danny Holman	1	-162/+0
	Clean up everything in the i386 arch directory. This code has been in dire need of refactoring for a long while. All the inline assembly functions and the data structures related to the architecture should be placed into their own header file. Now the scheduler can access registers and ISRs without having to deal with arch-specific code. Signed-off-by: Danny Holman <dholman@gymli.org>
2024-02-16	arch: i386: move IRQ functions to PIC driver	Danny Holman	1	-17/+26
	Move all the functions that control IRQ lines to the PIC driver. This allows the IDT controller to handle only raw interrupts no matter where they come from. Signed-off-by: Danny Holman <dholman@gymli.org>
2023-11-26	arch: i386: idt.c: install the ISR handlers	Danny Holman	1	-47/+62
	Actually install the ISR handlers to the IDT. Signed-off-by: Danny Holman <dholman@gymli.org>
2023-11-26	arch: i386: idt.c: remove the irq number from handler	Danny Holman	1	-1/+2
	Remove the irq number from the irq handler. This information is already stored in the ISR frame structure. Signed-off-by: Danny Holman <dholman@gymli.org>
2023-11-26	arch: i386: idt.c: call the page fault handler	Danny Holman	1	-3/+1
	Call the page fault handler when a page fault occurs instead of just dumping the registers and halting. Signed-off-by: Danny Holman <dholman@gymli.org>
2023-11-26	arch: i386: idt.c: add a stopgap to halt_catch_fire	Danny Holman	1	-0/+1
	Add a infinite while loop just in case the "hlt" instruction fails. Signed-off-by: Danny Holman <dholman@gymli.org>
2023-11-26	arch: i386: idt.c: remove unneeded define macros	Danny Holman	1	-23/+1
	Remove several preprocessor macros that serve no purpose and pollute the source file. Signed-off-by: Danny Holman <dholman@gymli.org>
2022-03-22	arch: i386: make serial_writestring inline	Danny Holman	1	-14/+8
	The serial_writestring function is small enough and platform-agnostic, and therefore it should be moved into the main serial header and marked as inline. Signed-off-by: Danny Holman <dholman@gymli.org>
2022-01-15	arch: i386: add support for IRQs and system calls	Danny Holman	1	-1/+5
	Add support for rudementary system calls and IRQ interrupts. Signed-off-by: Danny Holman <dholman@gymli.org>
2022-01-15	arch: i386: simplify IDT setup	Danny Holman	1	-4/+100
	Simplify the interrupt descriptor table setup and frame assembly. Signed-off-by: Danny Holman <dholman@gymli.org>
2021-10-09	arch: i386: include more information in IDT	Danny Holman	1	-40/+40
	Include information about the current stack frame in the IDT handler(s). Signed-off-by: Danny Holman <dholman@gymli.xyz>
2021-09-28	arch: i386: fix IDT exception handler	Danny Holman	1	-33/+49
	Fix the i386's general exception handler to actually work. Fix provided by Jon Sanderson (jjs295356@gmail.com). Signed-off-by: Danny Holman <dholman@gymli.xyz>
2021-08-30	i386: create idt.c and isr.s	Danny Holman	1	-0/+50
	Create files that add IDT support for i386. Signed-off-by: Danny Holman <dholman@gymli.xyz>
