Hello everybody, Because the tutorials from this website are dated and very complicated, I spent my afternoon making a modern tutorial on how to install Linux on the PS4. It's very detailed, but unfinished. I'm missing a lot of links that I'll add in the future. For now, you can find it on my GitHub . Thanks for everyone who's been supporting the community. Cheers!

DionKill wouldn't it be easier to install Linux on an internal drive, run gparted, connect the external drive, first partition fat32 50MB, second format to ext4, label psxitarch, have a distro on the desktop with the name "psxitarch" and one command sudo tar -xvzpf /home/ps4/Desktop/psxitarch.tar.gz -C /run/media/ps4/psxitarch but the guide is ok Qba-yakuza

Elokuba That method can work but not on every PS4 revision (Baikal system can't use the internal HDD), and it's super slow either way, but it certainly is another option, thanks for mentioning. Also I'm still gonna be updating this myself, there's a lot of stuff that's missing, like possible other distros I've definitely missed (I modified yours to fix language and a couple of things but haven't uploaded it yet), or how to update mesa drivers... A lot of stuff yeah.

I've just done a complete overhaul of my guide, at the cost of my sanity. If you want to check it out, you can find it here .

DionKill paranormal activity 😂

DionKill I was also thinking of putting it together good work

DionKill small gift https://mega.nz/file/kisU2CzZ#H0Ewgdg_tcjg7SW78JeN4_tUJ3ytAAoydAhh6b5WUgk and how to https://forum.endeavouros.com/t/enabling-zram-in-endeavouros/37746 🙂

Elokuba Hey that's awesome! I haven't thought of enabling ZRAM. Because Android already makes use of it, and honestly phones nowadays are just as fast as the PS4, it could definitely help with the fact that we have limited memory to work with. Also, I'm also going to try out this newer kernel. Thanks a lot for this! Just a little question, is there a repo for building the kernels or newer versions of Mesa? I think I found some but I'm not too sure.

Elokuba Thanks a lot man. I managed to find saya's account on some french forums I can't read and found quite a bunch of kernels hosted there. Do you know if those are the up-to-date ones? Or if there are plans for more newer kernels like crashniels' 6.15? Could I try to compile these myself?

New Linux Installation Tutorial by me

Wyv

DionKill you are right, I forgot to rename it, so your tutorial worked, but not for the command I had to use install-linux-hdd.sh not linux-hdd-install.sh idk if that is with the distro you used (im probably wrong lol) but now im into my install and its working

Wyv

so its not an issue with your tutorial its just my skill issue 😂

DionKill

Wyv Well, nice to know I don't have to rewrite the tutorial again!

Wyv

DionKill yea lol i would add the second command that i mention (install-linux-hdd.sh) because the one listed on there currently didn't work for me until i used the switched up version of it with install at the start instead of the end

Zram makes the system much more faster and feels more full pledge linux system.

Because of the Processes speed.

Logic:
From hdd to ram to hdd vice versa = bottleneck.

Factual:
Estimation etc...
PS4 internal Hdd generally offer around
75-88 MB/s read/write speeds, limited by the SATA II interface,

PS4 Pro Hdd if upgraded to ssd, still
generally offer around
550 MB/s read/write speeds, limited by the SATA IlI interface.

While:
Ps4 has a
GDDR5 memory speed of 176 GB/s,
Ps4 Pro has a 218 GB/s speed.
Both consoles use
8 GB of GDDR5.

Enter Zram.
DDR5 Speeds theoretical bandwidth of approximately 38.4 GB/s. For Zram

But limited to compression algorithm used with LZ4, Zstd etc...

Are the fallowing decompression speeds commonly exceed 1000 MB/s and can reach upwards of 2000 MB/s in fast modes. And this is estimated per 1 core only. Ps4 have 8 cores.

That is fast!, but not may explanation 😁

So no more back and forth from the slow hdd. And originally hdd is for slow i/o stored data.
Also hddswap setup will shorten your hdd/sdd lifespan.

Inshort
( Zram for ps4/pro is really recommended ) not only for efficiency, stability but for Longability.

Thank you for reading this long explanation🙂

Special thank you to:
Saya for bzImage with Zram, more.
Elokuba for CachyOS and updates.
Noob404 for this web, forum, technicals.

And the all the ps4 dev/modders since the beginning.

DionKill

Hig you are using zram? what setup are you using? are you setting up the entire ram as a zram pool, or only a few gigs?

asking because if someone has tested it and can approve that using the whole ram as zram pool is better than only allocating a few gigs for it, then i can update the guide to mention it.

Elokuba

Hig yes you are right the bottlenecks Sata and USB 3.0/3.1 i can't remember anymore i have 2 SSD inside and outside. there is a less harmful zram than swapfile but it is recommended to use both

Hig

DionKill sir do you need my full conf on Zram

Hig

🙂,

Hig

Good day, Yes im using Zram.

My Zram setup is entire system but i dedicate 2gb for Vram. with LZ4-HC algorithm.

Elokuba

Elokuba sorry no zram and swap file

DionKill

Elokuba Reading this once more, I saw that they mention to disable zswap to achieve best performance with zram. Is it disabled by default at a kernel level, or should i disable it by adding zswap.enabled=0 on the bootargs.txt?
EDIT: look at what they say about zswap on the Arch Linux forums in the note section near the top of the page. They say it interposes between zram and therefore needs to be disabled for it to have effect. I will try to add that to the bootargs.

Another thing that has come to mind, do you know about any newer kernels we can use on CachyOS? Newer kernels have gotten a lot of features and even native support for the DualShock 4 controller. Or should I be using another distro for that?

Hig Yeah sure, I'd like to see it

Elokuba

DionKill zram działa już z poziomu kernela piszę z telefonu sorry że po polsku

Hig

DionKill
About into newer BzImage/Kernel you can directly try to Chat Saya on discord.

Or in YouTube https://youtube.com/@saya7068?si=cwebcuC5P3jRfr4g

Send my regards tell him PeL-H1N1 😁 the that send you.

Saya he is the one. That makes my Vision on Zram for PS4, Happened. For a greater PS4Linux for all.

Elokuba

Elokuba only on cable

DionKill

Elokuba I used a translator, you say it works at a kernel level, which is true. I've decided to try out if using the bootargs and adding at the end the command to disable the zswap did anything but it stays enabled. I guess we'll live with that for now.

Elokuba

DionKill check this i add fix https://ps4linux.com/forums/d/304-cachyos-ps4-yakuza

Elokuba

DionKill is that what you mean?

Elokuba

Elokuba I am now doing zram and 1G swapfile support 10

DionKill

Elokuba Not really, the Arch Linux website says that ZRAM enables it's own swap called ZSWAP and that needs to be disabled, and normal Swap can stay on, at least that's what I've understood.

Elokuba

DionKill https://ps4linux.com/forums/d/304-cachyos-ps4-yakuza I edit now. That's why I left it with a little swap file support.

Hig

DionKill about on Z

DionKill Zswap is alternative for Zram, but its primarily for use in servers and desktop only. because of its nature, stored cache.

That is why i did not recommend it.
I assume all ps4 owners are a multimedia, gamer Users.

While Zram act has a Ram buffer.

But if i may suggest you can at least give the option to your guide Zram and Zswap
