Chiacchierando su Discord con @fabiosun sono emersi alcuni aspetti interessanti: la degradazione di prestazioni nel 3d è sostanzialmente responsabilità della patch che recita Fix Pat nei commenti. Se viene tolta in sistemi TRX40 le prestazioni 3d sono FINALMENTE PIENE, mentre se viene tolta in sistemi X570 la macchina non è utilizzabile e al 90% degli utenti si blocca ad una schermata gialla. A me si carica il sistema dopo un'infinità di tempo di attesa poco prima della schermata di login... poi si ha il boost prestazionale nel 3d, ma a costo di corruzioni grafiche pazzesche. A questo punto parrebbe che le cpu AMD per TRX40 funzionino correttamente col codice originale Apple per il modulo mtrr.c (quello a destra), mostro in figura quanto gira in rete riguardo alle modifiche che fece Bronzovska (aka Bronya) al kernel di High Sierra nella versione 10.13.3, che, tradotte adeguatamente, sono le attuali patch "vanilla" applicate a tutte le cpu AMD e a tutte le versioni di macOS. https://github.com/AlGreyy/AMD-xnu-4570.41.2-High-Sierra-10.13.3 Inoltre se l'accelerazione 3d non è attiva il boot avviene regolarmente su piattaforme X570 e B550 senza alcuna corruzione grafica... ma chiaramente senza accelerazione 3d non è possibile valutare gli effetti dell'eliminazione della patch 😞 ...qualche esperto di XNU che può aiutarci ad adattare questo codice alle cpu AMD consumer? https://github.com/AMD-OSX/bugtracker/issues/5

CloverX64-5122-jief-2709.1.zip attuale configurazione quirks sulla Z370 se qualcuno usa FakeSMC al posto di VirtiualSMC, meglio inserisca la versione di Slice inclusa in Clover iso o quella di Rehabman modificata da FreeJHack https://www.macos86.it/topic/3210-fix-fakesmc-backtrace-con-opencore/ da me funzionano all'apparenza correttamente, mojave, catalina e BS non fanno il boot e si bloccano immediatamente alle biglie rotanti i win10 e linux mageia, sia che vengano avviati con le custom entries che lasciato il setup nel config su auto.

Ciao, devi aggiungere l'opzione di boot manualmente sul bios per farlo puoi usare la shell (c'è la mia guida per efi shell) oppure app da windows ci sono guide sul forum a riguardo

ah ok, quindi la grafica sembra funzionante il titolo lo correggo io, no problem

dopo semmai posto la efi?

boot-arg -radvesa

si di fatto è questo, diciamo che non è corretta al 100% Se leggi la mia guida, ormai scritta da anni, quando al tempo 8 persone su 10 se ne fregavano della mappatura solo per il fatto "eh ma tanto ci sono le patch"... poi nel corso del tempo visto i problemi sempre più frequenti, l'instabilità delle patch stesse etc.. è stata poi fatta e usata sempre di più fortunatamente Nella guida vi è proprio scritto la motivazione, il come e perchè si effettua una mappatura, la parte successiva a questa è la definizione dei connettori delle usb, la quale è un ulteriore miglioria ma solo quest'ultima non può essere vista come mappatura sensata nel vero senso della parola quando poi si continua a usare patch etc Ma figurati nessun problema e per come si dice "nessuno nasce imparato" 🙂

only for the sake of testing I have installed successfully Catalina using an USB full installer and same EFi Instead, Big Sur hangs here: I have not removed my Thunderbolt card I am not using any ssdt in ACPI, only DevirtualizeMMIO in booter boot loader quirks Other stuff identical to the Proxmox config.plist (obviously with different kernel patches)

In vm i have a perfect system and i have not problem in bare metal with cinebench 15 i have an instant reboot when i try cpu benchmark sometimes it works and produces a result of about 7800 point often it reboots if it works in catalina for you, can you try to test this for 2/3 times ? ty

hi @iGPU mod you posted for Davinci works, tested yesterday Now I have solved my fresh installation problems (bad EFI structure for my fault) I have a problem with Cinebench 15 running cpu benchmark produces often an instant reboot ah..also Adobe need patching but then works pretty fine (nt tested intensively)

No Jaidy a minimal functionality to have correct resolutions and 2 monitor connected...this is valid also in Big Sur..but no acceleration is possible

Bios corruption could be your problem @meina222 try to re flash your bios I think it could solve your actual freeze main task should be to find exact things that inhibit us to shutdown or in my case to understand why in my rig now I have gpu acceleration with my same previous efi nvram could be related to this quirks but for now we have to study with classic process of errors and tries

There is no safe efi because this is an unexplored territory patches, boot loader and so on we have to find a proper mix of combinations of it to have, maybe a stable system. if you analyze your boot log I think now you will find in it some errors like unsincronized Tsynch Cpu or similar.. so maybe additional kexts are needed.. in my case executing cpu benchmark with cb 15 or 20 could cause an instant system reset.. using some apps instead like adobe or davinci need perl command patches ..but it is an Amd rig features for now

For now I miss only this in Proxmox way...

cb 15 FPS in baremetal 50 cb 15 FPS in Proxmox 120 to interested people, same Proxmox EFI in config added all patches as you can find in this thread

evvvvivvvvvva..... 🙂

a bit OFF Topic Clover boot loader booting fine on an AMD 3950 x thanks @iCanaro for filming 🙂 more infos here:

5) many apps need to be patched to work and some does not work well as in proxmox 6) if some thing change in the kernel...pufff ..our rig does not boot anymore these 2 points are common in every AMD rigs 3) Nvidia web driver seems to have problems to activate (only for me maybe)

hi @meina222if you know my history in trx40 task you will see I do not give up easily.. but here my main problem is GPU I do not want a radeon VII because it similar in benchmark to my Nvidia and I am waiting for Big Navi I have tested all I can for Nvidia and High Sierra but I am alone in this..and I am not able to debug clearly where my problem is However I have my disk ready and an usb pen to test if something new happen Redoing all debugging in MMIO as I did in the past to have this system working ...mmmhh now I have less strength for this..because trx40 in Proxmox works 🙂 If you have any ideas to test or a Nvidia to try on your rig..I will happy to be into this game again! 🙂 🙂

I am giving up on bare metal because for now I can’t install nvidia web driver in a correct way i use high Sierra as you know and in proxmox I have not problem i have solved SIP problem which help to load one kext for nvidia others 3 kext s are not loading. to have a correct sip behavior I have enabled AvoidRuntimeDefrag quirk with this I can enable and disable sip totally from high Sierra recovery without nvidia driver loaded I can’t test all the things I have in my mind to do i have an idea that proxmox is far better than bare metal, but thunderbolt study is better in bare metal because it depends only from our efforts and not from Linux missing bridges devices... if I recover my mental energies 😂 I will try to understand well nvram problem latest observation and studies by @igpu are now correct in my opinion On discord thread hackintosh Slav says to isolate mmio which could avoid proper nvram working idk if it is related or not...

with my previous installation done yes now I have deleted that disk and try to reinstall I can't see macOS installer icon in boot menu (after first installation part went fine)

When you have time try to boot in recovery and from terminal try csrutil status and see the output also try to change sip status and see this could be a big problem if you have to install some kext for not supported device by OS X

Mmmmh interesting..but slide value maybe differs from different pc configuration how do you have calculated this value for your pc? have you have done memmap calculation procedure?

Gigabyte users have to compare their bios settings and maybe agesa version in it msi and asrock seem to be less tricky to configure

@iGPUalso SIP acts weird in my system

it seems not to add any thing in XHC3: fabio’s iMac Pro 12-08.zip

@iGPUI have used previous one these are my results fabio’s iMac Pro IGPU SSDT SET.zip I can't see any device if I connect via usb (type c)

yep and this for me is a big problem

@iGPU i think only you for now are in bare metal could you post output of this terminal command? csrutil status thank you i think problem i have with nvidia driver is an old SIP problem

I use 060 release important and mandatory setting is DevirtualizeMMIO quirk enabled

@iGPU I think you win 🙂 fabio’s iMac Pro IGPU DevicePROP.zip

GPU performance is fine in Luxmark (it seems the same as Proxmox) when you have time try with Cinebench R15 (not R20)..it has a GPU testing related section Thank you for plist...I think if we are able to fill port 7 we are in a gold position 🙂

@iGPUgood morning I am trying now TY

Baremetal iMac Pro memory tab 🙂

here you go 🙂 TY fabio’s iMac Pro IGPU.zip

@igpu i see without ssdt stuff in systeminfo/thunderbolt

@iGPU thank you i will test later how can i check if they are loaded or not?

Thank you @tsongz i think problem is different, maybe driver related or acquantia id related not investigated so much because using i211 is fine for now..and the big problem for me is to have a working gpu with proper acceleration..i have not for now

@meina222if you have a disk with any osx installed...not a virtual file ..a disk i mean put my config and use a minimal set of kext and driver efi important things are: patches devirtualizeMMMIO enabled and then start it from that efi it is pretty simple. you could have some headache due radeon vii..or your xt..but it is more simple to try that to explain

yes 😉 thank you, in Bare Metal I see 32Gb module in Proxmox I see as you

Ok it works bare metal works in Catalina 10.15.6 for now I have no audio e no ethernet (aquantia is seen by default but no cable connected message) cpu benchmark are the same like Proxmox i can’t test gpu Performance Ok audio is fine and also ethernet is working (no Aquantia but intel i211 with SmallTreeIntel82576.kext

On amd osx discord
