0b6b0a46b4 not quite working stuff. Rethinking memory allocator. Maybe not buddy allocator. Basically use salloc for heap for now and talloc with O(log n) for system page allocation. A linear external allocator is not necessarily needed. Todo: finish talloc and add lock/alignment to salloc 2016-06-16 18:13:57 -07:00

b2254e207d Interrupt working (Except that I need to remap PIC). 
1. Fix a stupid mistake in idt dispatch table (IDT_ENTRY_NUM instead of IDT_ENTRY_SIZE)!
2. Figured out that before enabling APIC, the PIC is not completely disabled/remapped. Took hours to debug why immediately after enabling interrupt, a double fault happens when executing "mov eax, 0". Turned out that PIC maps timer interrupt to int vet 8, which is double fault in the vector table. The double fault normally pushes an error code 0, the ISR is expecting the error code but the timer interrupt does not push an error code thereby screwing up the interrupt stack completely. The kernel runs normally after "sti" after changing the int 8 vector to just "iretq". (Remapping the PIC: http://wiki.osdev.org/I_Cant_Get_Interrupts_Working#I.27m_receiving_EXC9_instead_of_IRQ1_when_striking_a_key_.3F.21). Oh FML, hours wasted..

Set up APIC. Timer setup atrociously close.
Bochs keeps giving the god damn triple fault (IDT broken)??

dddcd487a2 AVL Tree Test 
1. Added test for avl insertion and deletion (core functionalities).
2. Suppressed GCC's retarded multiline comment warnings.
3. Increased kernel heap size from 4k to 8k.

9ca5b1aa16 Development: 
1. Intergrated my salloc allocator
2. hal.c: Got rid of some gcc warnings, mainly int -> pointer.
3. entry.asm: 64-bit int immediate moved to a reg first then anded with another reg.
Refactoring:
1. Got rid of kernel_status_t, IN, OUT, OPT. secX does not have to be Windows does it?
2. Renamed _KERNEL_ABI to SAPI.
3. Refactored library functions / interfaces to as "static" and "_" as possible
4. Restructured "common" folder
