global enter_userspace ; Allows the C code to call enter_userspace(...).
enter_userspace:
push ebp ; Save current ebp
mov ebp, esp ; open a new stack frame
;==== Segment selector =====================================================
mov ax, 0x23
mov ds, ax
mov es, ax
mov fs, ax
mov gs, ax
; we don't need to worry about SS. it's handled by iret
;---------------------------------------------------------------------------
; We have to prepare the following stack before executing iret
; SS --> Segment selector
; ESP --> Stack address
; EFLAGS --> CPU state flgas
; CS --> Code segment
; EIP --> Entry point
;
;==== User data segmenet with bottom 2 bits set for ring3 ?=================
push 0x23 ; push SS on Kernel's stack
;---------------------------------------------------------------------------
;==== (ESP) Stack address ==================================================
mov eax, [ebp + 0xC] ; get uintptr_t stack
push eax ; push process's stack address on Kernel's stack
;---------------------------------------------------------------------------
;==== (EFLAGS) =============================================================
pushf ; push EFLAGS into Kernel's stack
pop eax ; pop EFLAGS into eax
or eax, 0x200 ; enable interrupt ?request ring3
push eax ; push new EFLAGS on Kernel's stack
;---------------------------------------------------------------------------
;==== (CS) Code Segment ====================================================
push 0x1B ;
;---------------------------------------------------------------------------
;==== (EIP) Entry point ====================================================
mov eax, [ebp + 0x8] ; get uintptr_t location
push eax ; push uintptr_t location on Kernel's stack
;---------------------------------------------------------------------------
iret ; interrupt return
; WE SHOULD NOT STILL BE HERE! :(
;==== Reset segment selector ===============================================
mov ax, 0x10
mov ds, ax
mov es, ax
mov fs, ax
mov gs, ax
;---------------------------------------------------------------------------
add esp, 0x14 ; reset stack pointer (20 bytes)
pop ebp ; reset value of ebp
ret ; return to kernel code

; Fancy processing for the common case of 2:1 horizontal and 1:1 vertical.

; The upsampling algorithm is linear interpolation between pixel centers,
; also known as a "triangle filter". This is a good compromise between
; speed and visual quality. The centers of the output pixels are 1/4 and 3/4
; of the way between input pixel centers.

; These are the handlers for when timers tick/elapse
; Note: These are jumped to using `de`, and so we can safely destroy
; `de` without pushing/popping it. `hl` and `bc` must be protected though.
; Note: The timer updating code is heavily redundant and could easily be

; Note: A physics delta of $10 causes things to move at 60fps. A value of $08
; would result in objects updating at 30fps, and $20 would still update
; at 60fps, but would update twice per frame. It's essentially a 4.4 fixed
; point physics update value, which is used to 'smoothly' scale the
; game speed to increase difficulty.
; Note: The engine seems to be able to handle things up to $F0, at which
; point things go sideways and it starts feeling like slow motion before
; falling apart when it hits zero (if un-capped).
; The max delta is meant to prevent the engine from falling apart, as we
; expect players to mess up well before then.
