PS3 Linux v2.6 Changelog:

  • Added ioctl PS3RAM_IOCTL_USER_TO_LPAR_ADDR cmd to ps3ram character device to convert user space addresses to lpar addresses
  • New PS3 VUART Dispatcher Manager (port 10) driver
  • New PS3 Dispatcher Manager Proxy character device driver for user space /dev/ps3dmproxy

AsbestOS Linux Kernel Installer v2.0 Changelog:

  • ICON0.PNG – Updated for v2.0
  • sfo.xml – Updated for v2.0
  • Makefile – Updated for v2.0
  • Progress bar and 128M bootmem fix.

To quote from [Register or Login to view links]: Well folks, it's done! I've been working with kmeaw last couple of weeks in asbestOS v2.0. This release is easyer to use, and eases the installation of Debian GNU/Linux in your PS3. Right now, it's the best way to overcome the loss of OtherOS feature. Hope everyone enjoys it!

To quote from [Register or Login to view links]: Just pushed my newest PS3 Linux drivers to remote GIT repository

You can access Dispatcher Manager from User Space through /dev/ps3dmproxy and in Kernel Space through ps3dm interface.

But take care, some HV services are dangerous and you should know what you are doing, you could e.g. overwrite your metldr or EID on FLASH So be careful.

I intend to write an updater for packages in the next days which will be able to update e.g. CORE OS package from Linux user space And then i will upload it.

For a long time i couldn’t decide where to implement the updater, in kernel space or in user space, kernel space makes e.g. easy converting memory addresses to LPAR addresses, but allocating large piece of memory in kernel is not simple, and implemnting HV services in kernel seems to me to be out of question, so i decied to do it from user space, more safe and easier

And we will need HUGEPAGE support for updater. I already tested it on my PS3 Linux and it works great One page is 16 MB large, more than enough for updating packages. The updater can allocate a huge page, store there the package, lock this page in memory so that swapper doesn’t move it to swap space, convert the address of the page to LPAR address and send it to Update Manager

I also added a new IOCTL to /dev/ps3ram character device – PS3RAM_IOCTL_USER_TO_LPAR_ADDR. It allows you to convert a user space memory address to LPAR address. We will need it for updater e.g., because updater has to send LPAR address of package to Update Manager. Here is an example how to use it: [Register or Login to view links]



Have fun and report any bugs to me please. HV hacking is cool

Just enabled ENCDEC and ATA debug messages in HV from Linux and now i can see those messages

[Register or Login to view links] HV rocks!!! Maybe i should enable RSX debug messages and see what they do.

Here is my new PS3 updater on Linux in action We don’t need PUP files or GameOS anymore to do updates It can be done now on Linux easily HV rocks It can inspect packages now Didn’t try updating yet, too dangerous, have to check everything 1000 times at least because i don’t have a NOR flasher

In case, you are wondering what those repo node value numbers mean, then read my HV page about UM inspect package service.

And here is an example if a package is damaged. I intentionally modified a package and let UM inspect it, It returns error

If SONY is reading it, they will know what those numbers mean

As i said previously, i allocated a huge page with mmap(MAP_HUGETLB) and stored there the package, then i converted the user space address of the buffer to LPAR address and sent a UM inspect package request to Update Manager through my /dev/ps3dmproxy.

To make Linux preallocate some huge pages during boot, i passed boot parameter “hugepages=1″, it means Linux kernel should preallocate 1 huge page of size 16 MB. And an application can grab this page with mmap syscall.

I will upload it soon Stay tuned. PS3+Linux+HV rock !!! And i know where to patch Update Manager in HV process 6 so it will allow us to do downgrades without Product Mode I also improved my DM drivers, will upload them soon too.

Extracting packages with Update Manager works now also

Nice, but asbestos can already boot Linux from the internal HDD using the linux.img on the root of the filesystem...

Making a new firmware and booting it from vflash seems a bit OTT compared to that unless it has more features or is a bit quicker or something?

I'd rather mount the ps3 filesystem in Linux and boot from that rather than partitioning, if only someone could make a way of decrypting the ps3 filesystem...

as for the kernel , full access to the GFX ram? does that mean we can actually use the video ram as ram instead of swap space now? if so does someone have a compiled kernel?

The development of Linux' return on PS3 has been developing a good deal last two weeks from AsbestOS from 1.5 to 3.0 version and loading through USB media, to this very intering (and desired) development to give it full OtherOS back.

Very much anticipating this

Wow, this seems VERY promising. I like the idea of having petitboot, which will simplify the switch between GameOS and OtherOS. All the work graf_chokolo put on HV hacking is awesome! Finally an unrestricted system! Looking forward to this. We will probably be able to triple-boot soon; imagine GameOS fw.355 + GameOS fw.356 + Ubuntu = freaking sweet!
