Operating Systems and Porting / [NEWS] Linux 6.13 is out!

« on: January 19, 2025, 09:12:17 pm »

Things are just getting better. The 6.13 has a bit of changes, however most of them are not really related to RaptorCS or OpenPOWER hardware. Having said that it's welcoming to see changes related to Intel Xe3 (which is not yet working with non-x86 platform). I am hopeful in a year or two we might be able to run Intel Battlemages-GPU cards.

Operating Systems and Porting / [NEWS] FreeBSD 14.2

« on: December 03, 2024, 03:33:38 am »

More details could be found at https://www.freebsd.org/releases/14.2R/announce/

I am unsure how many of us are actually using FreeBSD but hey there are great usecases out there that FreeBSD shine brighter than Linux for example the ZFS

General OpenPOWER Discussion / Re: POWER11 on the horizon?

« on: November 24, 2024, 05:51:44 pm »

Another post from Phoronix confirming that POWER11 is likely to be debut in 2025. Let's hope it is actually less binary flop than that of POWER10

It's yet another great version from Fedora. Everything runs as expected for PPC64LE arch

Applications and Porting / [DEV] Binsider is a nice analysis tool ELF binaries

« on: September 30, 2024, 08:54:17 pm »

This tool is quite useful IMHO for developers who want to peek inside the ELV binaries to find bugs or simply to reverse the application logic.

Operating Systems and Porting / [NEWS] Linux 6.11

« on: September 16, 2024, 01:35:01 am »

It's officially out. Not much news related to PowerPC unfortunately.

However preliminary support RDNA4-based AMDGPU is in.

Btw, RDNA2-based cards like 6800 continues to work.

Fedora 41 will ship with 6.11 (or 6.12).

Applications and Porting / Re: Medal of Honor: Allied Assault War Chest (OpenMoHAA)

« on: August 30, 2024, 02:12:46 am »

@tle

Great! I see that Smallmodel accepted your pull request.

Can you tell me if OpenMoHAA works on your computer?

I noticed Smallmodel made some changes after some suggestions from Cowcat5150

https://github.com/openmoh/openmohaa/issues/332

Cowcat5150 is porting OpenMoHAA to MorphOS, which is a 32-bit operating system for PowerPC computers. I don't know the issues with OpenMoHAA for Linux on Raptor Computers, but maybe you want to try the most recent version.

I am unsure because I am still trying to find the game and a Windows machine to install it for the assets files

Applications and Porting / Re: [DEV] An attempt to package chromium for ppc64le in the official Fedora DNF repo

« on: August 30, 2024, 02:11:57 am »

TLE I saw your post on the Fedora bug report on Chromium which I opened and I also saw a post by another user who says to try the version that ends in 88-2. I have just installed the latest version which should be after 88-2 or 99 and as I also reported on Fedora Bug, it still doesn't work and always makes the same error and freeze...

Please contribute to this ticket https://bugzilla.redhat.com/show_bug.cgi?id=2308642 instead

I am more than happy to give OpenMoHAA a try. Thanks for sharing the news with us

Applications and Porting / Re: [DEV] Add ppc64le support for generator-rs - need guidance

« on: August 13, 2024, 04:22:44 am »

If I'm reading https://github.com/Xudong-Huang/generator-rs/blob/master/src/detail/asm/asm_riscv64_c_elf.S correctly, basically what it's asking for is a function prologue to save registers. This must obey the OpenPOWER SysV ABI, so it would be something like

mflr r0
std r0,16(r1)
mfcr r0
std r0,8(r1)
stdu r1,-FRAMESIZE(r1)

and then start saving your callee-saved registers into the frame, which is basically any non-volatile GPRs and FPRs your routine might touch.

Not quite sure what it's doing with the green task routine but I only read the source cursorily.

From my understanding the RISV asm consists of 3 functions:

* The prefetch function is essentially a no-op function
* The bootstrap_green_task function sets up arguments and then jumps to the address contained in register s4, effectively starting a new task or function.
* The swap_registers function saves the current values of a large number of registers (both general-purpose and floating-point) to memory and then restores them from another memory location

Thanks for show me the OpenPOWER SysV ABI example, let me do a bit homework

Applications and Porting / Re: [GAMES] Quake 3 source port with Vulkan renderer (vkQuake3)

« on: August 13, 2024, 03:59:34 am »

Quake3e still needs a bytecode compiler for ppc64le if you were still interested in helping with that.

It would be great if someone who has more experiences to tackle https://github.com/ec-/Quake3e/issues/232. I am more than happy to tag along to learn and help out whatever I could

In the meantime, the patch sets for Baseline Interpreter/Compiler in Firefox 128ESR are now available. I'm typing this in it myself and the test suites all pass, so I'm pretty confident it will work well.

https://www.talospace.com/2024/08/baseline-jit-patches-available-for.html

Great work. Looks pretty solid, it has not crashed for me yet. I reckon when we get WASM working perfectly, we could try to get your patchset merged downstream with Fedora or Debian
