  • f9b3df8b60 VMM half-done. PMM refactored. Haven't got a chance to touch the HAL yet. secXsQuared 2016-06-25 14:40:47 -0700
  • 8da028f518 Eventually went with not using in-place linked list for PMM (Don't really want to mix up PMM and VMM). So yeah, now keep trace of those physical pages on kernel heap, Windows does that, linux does that, I have to do that since there are more attributes(paged/non-paged) that the kernel requires. Hmm finished PMM alpha and redefined all those PMM/VMM interfaces. The code is still broken right now. secXsQuared 2016-06-25 00:25:54 -0700

  • 8ef4b18684 Actually buddy allocator is good.... secXsQuared 2016-06-17 02:18:07 -0700
  • 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 secXsQuared 2016-06-16 18:13:57 -0700
  • 95bb791d71 LALLOC coming. Need to make salloc and lalloc thread-safe. secXsQuared 2016-06-16 00:23:06 -0700

  • 0188fe66a5 Push missing write/read ports w/ diff operand sizes. secXsQuared 2016-06-13 23:57:38 -0700
  • 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.. secXsQuared 2016-06-13 23:33:31 -0700

  • 9ca5b1aa16 Development: 1.
