Editing Talk:PS2 Emulation

==Regs==

**1040000000 VU1 regs, mapping like on VU0.
**1050000000 VU1 micro data  memory (1100C000 on real ps2 and pcsx2 debugger) size 0x4000.
**1050004000 VU1 micro data memory mirror (1100C000 on real ps2 and pcsx2 debugger) size 0x4000. Likely mirrored 2 more times on 8000 and c000
**104000C000 emulator place here VU1 constants used in popular operations. Eatan/eexp constants, masks for clamping, etc. Similar array can be found in Pcsx2 (mVU_Globals), Dobiestation (atan_const, etc), Play! (GenerateEATAN, etc.)
**1030004000 emulator place here VU0 constants used in popular operations. Like above (vu0 don't have efu so placing there efu constants for eatan/eexp is pointless, but there they are).

<pre> I have added vu1's regs, all i did was copy vu0's info and replace 0x10300 with 0x10400 in notepad++, so i'd love it if you could rename regs if they are wrong or make sure that the info i have added is correct --Scalerize </pre>

=Misc info=
Some data that eventually need to be posted on main emulation page. All data posted here is obtained from jak tpl (so called v1) emulator. All data is confirmed in code itself, no guessing (unless said otherwise). Time to start releasing that old work to public.

*Settings ignored by emulator (there is more than that):                   https://pastebin.com/Hm9bfnF6
*Settings which use bool (0/1, emu accept true/false on/off too) as value: https://pastebin.com/iaLLAXHn
*Settings which use double float as value:                                 https://pastebin.com/cZvxCb6K (unk max values are likely DBL_MAX )

==Misc misc info==
*Both settings do the same thing:
 --external-hdd-fix
 --cdvd-determinism

 --ee-kernel-hle
 --ee-injection-kernel

*Setting take unused value:
 --ee-cache-breaks-block
 No matter which value is used, 1 is set.

==Few popular misunderstandings==
*vu-xgkick-delay take integer between 0-31 (confirmed on both emu and compiler side), and not float (0.5 is invalid, will be truncated to 0 probably)
*Cop2 rounding in pcsx2 is governed by "EE/FPU" rounding setting, not by VU or VU0.
*Cop2 clamping is hardcodded in pcsx2 as far as i know, if no then is likely also governed by EE/FPU setting not VU/VU0
*xx-no-clamping setting is not really no clamping known from pcsx2. This is special mode which can be used regardless of other clamp commands. To compare pcsx2 have similar mode only for FPU (Full), to fully mimic that mode we still need fpu-to-double enabled.

==ee-native-function==
Emulator have set of predefined functions used in popular PS2 SDK libraries. Those function are highly optimized to run natively on x64. <br>
'''--ee-native-function=name,address''' under the hood this is hooking selected address, and replace it with jump to predefined function. Functions available in JAK TPL emu:
 memset      | fptoui           | ieee754_sinf
 memcpy      | fptodp           | ieee754_cosf
 strlen      | dptofp           | ieee754_sqrtf
 strcmp      | fabs             | asinf
 strcasecmp  | fabsf            | acosf
 litodp      | ieee754_atan2f   | sinf
 dptoli      | ieee754_asinf    | cosf
 floatdidf   | ieee754_acosf    | sqrtf

This drastically reduce emitted code size for selected function. Additionally there is no need to recompile that at all, emulator just emit jump to label, and that's all. Additionally emulator advance delta clock to compensate cycles which will be normally took by original function.
<br><br>
Example ee_native_floatdidf
 vcvtsi2sd    xmm0, xmm0, rdi
 vmovq        rax, xmm0
 retn

This is what real floatdidf looks like originally in ps2 mips, you can imagine that recompiled x64 code will be much longer. Every single instruction will be translated/recompiled separately.

 jr           $ra
 addiu        $sp, 0x30
This is corner case example as floatdidf convert a 64bit signed integer to IEEE double, and PS2 developers generally had no reason to use doubles (fpu/vu are operating on 32 bit floats). But you can see that whole conversion is practically done in 1 opcode, while ps2 take massive function to do this. Other functions are usually less optimized, but still really worth it.

==EE/VU injection==
"Injections" are special sets of precompiled functions, idea is known better as HLE emulation. Available injections can vary depend on ps2-compiler.self, because that's where lookup for available functions is done. This literally replace code that normally is recompiler, with optimized version when address and hash match. Probably not many games can use this. Good candidates are games that use the same engine as currently released ps2 classics. Many times VU1 programs are reused by the same developer. 
<br>'''VU1'''
*Name + offset in JAK TPL compiler
*unk1
*VU1 mpg start address (divided by 8)
*Some kind of hash to ensure that correct part of microprogram gets replaced
*Many other unknown values

Same goes for "kernel" injections, they are also based on ID + Hash + address. Generally all "injections" should be safe to be enabled by configs. There is really small chance for hash/address(and id) collision. Not to be confused with "native" / "native-patch" !

==Fast Accurate MUL Implementation==
While Accurate MUL is implemented as very resource heavy fully fledged soft float operation, there is theoretically less accurate but very fast "accurate MUL" available. Surprisingly this is not copy pasted PS3 implementation (no need to reach Olympus from Lop Nor this time). While this implementation is assumed to be less accurate (than soft floats), result should be the same as with soft floats. r14 and esi are source floats for operation. So, here it comes:
<pre>
mov     edx, r14d
mov     eax, esi
xor     eax, r14d
shr     edx, 23
and     eax, 80000000h
and     edx, 0FFh
jz      mul_end         ; mul by denormal
mov     ecx, 817h
bextr   ecx, esi, ecx   ; esi >> 23 & 0xFF
jz      mul_end         ; mul by denormal
and     r14d, 7FFFFFh
and     esi, 7FFFFFh
add     edx, ecx
or      r14d, 800000h
or      esi, 800000h
imul    rsi, r14
shr     rsi, 23
vcvtsi2ss xmm0, xmm0, rsi
vaddss  xmm0, xmm0, cs:(float)0.5
vmovd   ecx, xmm0
shr     ecx, 23
lea     edx, [rcx+rdx-115h]
cmp     edx, 0FFh
jle     case1
mov     ecx, 7F800000h
mov     esi, 7FFFFFh
jmp     case2

case1:
add     ecx, -150

shl     ecx, 23

cmovle  ecx, ebx

But keep in mind that GS regs can be "duplicated" for different emulation stages. GS is jited too, so it should have kind of pipeline too.
"Implement a EE memory patch for ratchet up your arsenal" Game write data using qmtc2/ctc2 and expect VU0 to still run at this point, which is not always true. Mega high vu0 mpg cycles could potentially push it little further. Patching that will be pain just because Ratchet use code overlays. This mean you need to patch game image with the same patch in more than 20 places. Because what you see in pcsx2 debugger / ps2dis will change depend on stage you play now. That's why PS3, and PCSX2 use dynamic jit patches (pcsx2 use it for different issue tho). --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 14:20, 27 February 2023 (CET)

== no-clamping ==

Sup. Can i know how no-clamping behavior was tested to confirm that "The default emulator's behavior cannot be set by CLI commands."? Because that doesn't sound right, and emulator explicitly set 0 or 1 on init, which is confirmed in emu code. What can happen, is that other clamping settings were changed during test, and that affected result. But looking at code i don't think there is any possibility that something "in between" exist. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 09:33, 21 June 2023 (CEST)



<br>It is based on a test I did on Sly Cooper 2. If VU1 Clamping was set to 1 or 0, the game crashes. If left empty, game works fine. --[[User:Scalerize|Scalerize]] ([[User talk:Scalerize|talk]]) 14:58, 21 June 2023 (CEST)
* Do you remember when game crash? Right after ps2 logo, when going ingame, any specific level, etc. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 15:32, 21 June 2023 (CEST)

<br>Right after the ps2 logo if I recall correctly --[[User:Scalerize|Scalerize]] ([[User talk:Scalerize|talk]]) 16:34, 21 June 2023 (CEST)
* I think there was typo in config you tested. Crash right after PS2 logo is usually caused by unsupported command (emu will print "Unhandled option for this build/platform" and hit UD2 right after). Missing separator, typo, upper case characters, or something else was wrong. I double checked emu code, and it is set or not set (0 or 1). Recompiler parts which use it also test only for 0/1, and setting this command don't affect anything else. I'm going to leave description as is because without PS4 i can't test it by myself, but i'm really sceptical about it. :P --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 16:46, 21 June 2023 (CEST)

So, after taking some time to think about it, I had remembered that the game would crash right after the first pyramid fmv at the press start screen. But yeah, leave as it is. You have the upper hand in removing/adding anything you like --[[User:Scalerize|Scalerize]] ([[User talk:Scalerize|talk]]) 17:19, 21 June 2023 (CEST)

== Config table with IDs from Jak emu ==

Table from Jak emulator, this is how emulator config parser see data from cli. Please don't edit typos, etc. This is how it is in emulator. I'm leaving it here, so main page can be slowly updated with data from table if needed. Emulator translate commands to ID, then use ID in jump table in parser to apply cfg. ID is not guaranteed to be the same between emulators, but i didn't tested that. Comments match id too. Script for ida to dump this info will be posted soon. UNK value is not critical for anything, but it is used for something, and it is part of original table. This table is missing few commands which are parsed outside of main cfg routine.

Note: Few commands is accidentally read with = , for example --elf-symbols=. Commands like this possibly expect == to be used. Anyway, good for us all of those cmds are meaningless.

===Script===
IDA Script to dump this info, should find all by itself. Should... Tested on jak emu, and rogue emu. Keep in mind that it will dump only to ida output window, to dump it to file you need to modify it by yourself. Script will separate fields by comma. Output will be ID, UNK, COMMMAND, COMMENT. Next commas are eventually from config comment itself.
