Hello. Sorry for reaching by using Issue request, but I don't know how else to reach you, and there is really not a ton on information over the internet, so I wanted to ask you for help. I wanted to do fresh installation of Gentoo Linux on the PS3 Slim with OtherOS++. I have problem with kernel, and while searching I have found your repository. The issue I have is that after compiling and using source from https://kernel.googlesource.com/pub/scm/linux/kernel/git/geoff/ps3-linux my gentoo doesn't recognize partitions /dev/ps3dd1 so it fails to boot. I am able to boot using Red Ribbon kernel (old) inside this Gentoo environment, so it should be possible to work. This problem with linux not detecting partitions on the PS3 HDD is hunting me for some time now. I know this is related to OtherOS++ working a bit differently than the original OtherOS, where otherOS was installed on /dev/ps3da1. OtherOS++ uses /dev/ps3dd and for some reason nothing except Red Ribbon kernel is able to detect it. Other kernels with OtherOS++ only see single /dev/ps3da device with no partitions. I see that you are actually using Slim too, so probably also OtherOS++ right? Please let me know if you can help me somehow or give some extra bit of information to make this work. Again, sorry for reaching so directly with GitHub, but it's really hard to find some information about this.

Cześć @damiandudycz,

No problem with you contacting me like this. Though I am not sure if I will be able to help. As explained in the readme section my setup is somewhat different. From the start I chose not to mess with the internal PS3 drive and decided to go for an external USB instance with the Linux system. Possibly a slower solution, but isolated and working.

I can confirm that I am not getting access to the PS3 hard drive from the Linux kernel, though I get it (at least the drives listed in a proper manner when using for example fdisk -l) in the Red Ribbon kernel.

I just checked the loaded modules across the two systems. This would be under Red Ribbon:

I also compared the two results. image image and it looks to me like the module ps3enddec is missing.

Maybe you should ask your question in those threads: https://www.psx-place.com/threads/tutorial-read-warning-installing-red-ribbon-linux-on-rebug-4-81-2-4-84-2-d-rex.16419 https://www.psx-place.com/threads/eflash-decryption.29510/ or look for an answer here: https://www.psdevwiki.com/ps3/Mounting_HDD_on_PC This might be helpful as well: https://github.com/Sorvigolova/ps3encdec

Thank you so much for the response :) Btw. "Cześć" - are you Polish too, or just happened to know this word? :)

I tried your kernel directly copied to my current setup just to see what happens, but as expected it didn't recognized the ps3dd and booted to initramfs console instead. Im currently using Red Ribbon 6.2 kernel as a temporary solution as well, just to be able to boot, and it works. It's version 3.12.6-red-ribbon-powerpc64-ps3.

I noticed that I have a lot less modules loaded tough, at least when using lsmod. I don't have ps3enddec module loaded at all. So either I don't need it, or it was compiled directly to the kernel, but from one of the links you provided, it looks like it's actually a module used to decrypt flash storage and not HDD. Please correct me if I got this wrong though.

But from another link you provided, I found this: Implemented PS3 partition support in Linux kernel. See patch 0035-ps3-partition.patch here http://gitorious.ps3dev.net/ps3linux/kernel-patches-35 So perhaps this is the patch that I need to add to kernel to be able to read the partition table. I don't know. Links are down unfortunately, but still this is a new information, so small steps forward, and maybe I will get somewhere :).

One more thing I noticed, when using red ribbon kernel - I called: udevadm info -a -n /dev/ps3dd And it shows the device: looking at parent device /devices/ps3_system/sb_04: KERNELS=="sb_04" SUBSYSTEMS="ps3_system_bus" DRIVERS="ps3disk" So apparently if Im reading this correctly, red ribbon kernel is using driver named ps3disk, which is build directly into kernel, as I don't see it listed as module. Not sure tough if Im interpreting this right, this is the first time Im doing something like this on Linux.

Thank you so much for your help!

I am Polish too :)

... one more link that could possibly help you (from as it looks like another Polish guy): https://www.psx-place.com/resources/ps3-hdd-decryption-helper.1293/

There seem to be some drivers provided. I haven't tried it though. Maybe I will. But as mentioned before my use case was somewhat different. I have had no use of accessing PS3 HDD drive. I just needed a more or less up-to-date running system with connection to the Internet, for which the USB solution works just perfect.

Pozdrawiam :)
