Code: [Select]
cat /sys/power/mem_sleep
[s2idle]

It is s2idle... better than nothing I guess

Btw, which kernel config you enabled? Keen to try that on Fedora 39 too

77
I too can confirm Suspend to Disk is missing with Fedora 39 (kernel 6.5.0). So I think this feature is not supported *yet*.

I also tried suspend to RAM on Fedora 39 and it works for me.

Great thanks to ClassicHasClass for having a look at the issue I reported at https://github.com/dosbox-staging/dosbox-staging/issues/2789

Operating Systems and Porting / [NEWS] Linux 6.5
« on: August 27, 2023, 06:08:10 pm »
It's finally out! https://www.phoronix.com/review/linux-65-features

Unfortunately it does not have much changes related to OpenPOWER. One change with Power10 is DEXCR Support In and that's pretty much it

It turns out PPC64LE JIT is currently disabled

https://github.com/dosbox-staging/dosbox-staging/commit/515161087c8e66b57f8c73ec289ae4b3a4f4548a

Upstream SVN r4424 started refactorization of cpu module, and it breaks
those backends; to be re-enabled once refactorization is done or when
we'll have time to fix it ourselves.

We all have heard about the JIT patch of our fellow member ClassicHasClass for the original dosbox which could be found here https://www.talospace.com/2020/01/dosbox-jit-on-ppc64le-and-how-you-can.html
His patch though not apply cleanly to the dosbox SVN trunk, however with a bit of tweak, it still work perfectly with PCPBENCH reports 28.3fps!!

Another fork of dosbox is dosbox-staging that supports PPC64LE JIT out of the box (again thanks to ClassicHasClass) is another great option but performance is not as good as that of patched JIT dosbox. The PCPBENCH can get up to 17.1fps
(ref: https://github.com/dosbox-staging/dosbox-staging/commits/main/src/cpu/core_dynrec/risc_ppc64le.h)

I am going to dig in the source code of dosbox-staging to see how they did the PPC64LE JIT and why it is slower


EDIT: Great thanks to ClassicHasClass for the Pull Request https://github.com/dosbox-staging/dosbox-staging/pull/2828

Now dosbox-staging can achieve 41 fps!

What is `blink`?

Applications and Porting / Re: [GAMES] Quake II RTX!

 :D The PR has been merged! I can say the game now can be compiled successfully on PPC64LE without any downstream patch


84
Due to lacking of JIT, the performance is obviously subpar to that of ARM64

Ref: https://github.com/ptitSeb/box64/issues/242

Let's hope they would wrap up the work for RISC-V JIT quickly so they could spend time on porting JIT for PPC64LE

Title: Pillars of Eternity
Platform: Linux
Arch: x86_64
Game Engine: Unity3D (OpenGL)
Rating: 1/10 (Super SLOOOOW to load up)

The installer (which is mojosetup-based) could not be run with box64 so I have to use a native x86_64 Linux box to run the installer and copy all files to my PPC64LE box.

Code: [Select]
box64 ./PillarsOfEternity



No error in the box64 output however the loading time is excruciating! It took 20min to load to the first screen! Then any other click to New Game does not respond. That's the furthest I could get to with this game.

86
It's good to know Box64 0.24 has already supported PPC64LE.

I am curious to see how it would be able to run x86_64 titles. Firstly lets compile the app:


Code: [Select]
git clone https://github.com/ptitSeb/box64.git
cd box64
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo -PPC64LE=1 -DPAGE64K=ON
make -j32
sudo make install


NOTE: I am running Fedora 40 (rawhide) which we all know use 64K Pagesize, hence the PAGE64K is enabled.

General Discussion / Re: Highpoint SSD7202 - M.2 NVME RAID card
« on: August 21, 2023, 05:41:31 pm »
Mr Shun from Highpoint support has informed me the company does not support ppc64le so there will be no drivers. I will dig in further how people could get the sibling SSD7204 running on FreeBSD (and Linux)

> The card needs a PCIe switch, because the Raptor mainboards doesn't support bifurcation.

I do not think the card needs PCIe switch. The official website says: "Any PC Systems or Motherboard with an industry standard PCIe x8 or x16 physical Slot (Bifurcation is not required)"

88
Yay! PPC64 RPM is back Fedorans!

I also bump the package to 1.3.1.

Nice work. I have one question: for PPC64 BE, would Power Mac G5s running 64-bit Linux run afoul of the -mcpu=power7 flag?

I don't have the answer but I think it should work.

General Discussion / Highpoint SSD7202 - M.2 NVME RAID card
« on: August 19, 2023, 09:04:06 pm »
Souce: https://www.highpoint-tech.com/nvme2/ssd7202

This card is around $300 USD and supporting 2 x NVME M.2. From what I know, it does not offer any binary driver / softwares for ppc64le so I have submit a Support Ticket with Highpoint to find out more details if there are open source driver in the upstream Linux kernel and how well they support ppc64le architecture.

Wondering if anyone has tried this Highpoint card?
