2024-02-24arch: i386: cleanup everything and reorganizeDanny Holman
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>
2024-02-16arch: i386: move IRQ functions to PIC driverDanny Holman
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>
2023-11-26arch: i386: pic.h: make register_irq_handler accessibleDanny Holman
Make the register_irq_function accessible from files including pic.h. Signed-off-by: Danny Holman <dholman@gymli.org>
2023-11-26arch: i386: pic.h: change all chars into uint8_tDanny Holman
Make all variables with char or char* type into uint8_t. This makes the system more consistent and issues fewer compiler warnings. Signed-off-by: Danny Holman <dholman@gymli.org>
2022-01-15arch: i386: fix coding style issueDanny Holman
Make the inline assembly calls consistent across different i386 files. Signed-off-by: Danny Holman <dholman@gymli.org>
2021-09-28arch: i386: add PIC register supportDanny Holman
Add functions that let the OS read the internal state registers of the 8259 PIC. Signed-off-by: Danny Holman <dholman@gymli.xyz>
2021-09-28arch: i386: add support for 8259 PICDanny Holman
Add support for the 8259 programmable interrupt controller. Signed-off-by: Danny Holman <dholman@gymli.xyz>
