37 hourskern/amd64: cpu: Make GDT per-cpu to match TSSIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskern/amd64: Move i8259/uart init to chipset_init()Ian Moffett
These are chipset specific and independent of the processor, therefore they must only be initialized once. Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskern/amd64: gdt: Load GDT before setting GS_BASEIan Moffett
If we update the GDTR after setting GS_BASE, we wont be referencing any valid data anymore. Switch out the GDTR early on. Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskernel/amd64: Add task state segment logicIan Moffett
This commit implements the task state segment and splits up processor initialization into two seperate stages. The cpu_conf() function is apart of the first stage and sets up things that should be going by the time the kernel is started / early init. The cpu_init() function runs later functions that initialize further platform specific subsystems. Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskern/amd64: boot: Initialize I/O APIC *once*Ian Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskern/amd64: Add I/O APIC initialization codeIan Moffett
This commit introduces the initial I/O APIC driver code that does basic initialization i.e., grabbing base address from MADT, masking each pin, etc. Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskern/amd64: boot: Disable the i8259 chip on bootIan Moffett
To avoid interrupt conflicts on some machines with the I/O APIC, disable the legacy i8259 chip by default Signed-off-by: Ian Moffett <ian@osmora.org>
