Operating Systems and Porting / [NEWS] Fedora 37 has arrived!

« on: November 15, 2022, 05:17:15 pm »

To me it is a great release because many annoying issues such as stuttering graphic performance with mutter is gone. Plus many packages are now more up-to-date which really helps with getting amdgpu driver running for RDNA2-based GPU.

Having said that it sucks to know that Fedora no longer enable hardware decoding for Mesa, I have to manually revert the patch to compile my custom RPMs.

Applications and Porting / [DEV] bx library now supports building on ppc64le with gcc and clang

« on: November 14, 2022, 07:52:15 pm »

Good to know that the game library bx can be compiled successfully on ppc64le linux

* https://github.com/bkaradzic/bx/pull/290
* https://github.com/bkaradzic/bx/pull/291
* https://github.com/bkaradzic/bx/pull/292

How to compile it?

Code: [Select]

git clone https://github.com/bkaradzic/bx.git
# make sure you build bx/genie binary on your ppc64le first because the bundled genie is for x86_64
./tools/bin/linux/genie  --gcc=linux-ppc64le-gcc gmake # for GCC
# or
./tools/bin/linux/genie  --gcc=linux-ppc64le-clang gmake # for clang

make  -R -C .build/projects/gmake-linux-ppc64le-gcc/ config=debug64 # for gcc debug version
make  -R -C .build/projects/gmake-linux-ppc64le-clang/ config=debug64 # for clang debug version

make  -R -C .build/projects/gmake-linux-ppc64le-gcc/ config=release64 # for gcc debug version
make  -R -C .build/projects/gmake-linux-ppc64le-clang/ config=release64 # for clang debug version

So what does it mean? It means that we are just a tiny step closer to have minecraft compiled out of the box without any patch

GPU Compute / Accelerators / AMD Radeon 6600 XT working with kernel 6.1.0!

« on: November 08, 2022, 02:37:45 am »

EDIT: Kernel 6.1.0.rc3 (64K pagesize) has finally get this card working! - no need to add any amdgpu.dc or aspm option

TL;DR

• 5.19.x - NOT WORKING
• 6.0.x - NOT WORKING
• 6.1.0 - WORKING
• 6.2.0 - WORKING
• 6.4.0 - WORKING
• 6.5.0 - WORKING

The last time I touched Navi was 2 years ago. I could not get 6900 XT card running on Kernel 5.15.x.

Well time to try again with the Powercolor Fighter 6600 XT (just because its dimension fit the Blackbird)

Two issues I find:

* HDMI - no video output, I have to use DisplayPort. Not a deal breaker. In fact this issue has always been there with amdgpu for quite awhile
* After restarting the computer, there is no video output to DisplayPort. To workaround this issue, I simply shut down and turn the computer back on. The `dmesg` shows:

ata3: reset failed, giving up

Just wondering if anyone has bumped into similar error

GPU Compute / Accelerators / Intel Arc A770 - failed experiment

« on: November 01, 2022, 10:40:24 pm »

My local computer shop has finally got the first batch of A770 and A750!

After two years of waiting, I finally have my hand on this dGPU.

I am going to spend a day or two to get this working on Fedora 37. AFAIK few things must be prepared:

* Latest kernel 6.1
* Mesa 22.2 or newer
* Latest GuC firmware
* Explicitly declare i915 module probe in grub menu entry

Operating Systems and Porting / [DEV] Trying out Chimera Linux

« on: October 30, 2022, 07:31:01 pm »

Please note the distro is still being in heavy development

This Linux distro is developed by q66, yes the same person behind the Void Linux distro. It has distinctive differences to other distros:

* Adopt BSD userland utils
* Run musl C instead of glibc
* dinit instead of upstart or ..systemd
* support many archs for example riscv, ppc64le, x86_64, etc
* Adopt apk as package manager
* Use clang/LLVM instead of GCC
* GNOME as the de facto DE

The installation process is quite straight forward and primitive as this stage as it does not offer you any installer yet. The GNOME 43 is quite snappy compared to that of Fedora 37 despite of lacking some core gnome softwares (q66 will be adding them in the near future). Some features are not working correctly for example setting datetime in GNOME control center. There will be some hurdles to overcome to workaround GNOME integration with systemd. Overall I think this is a promising distro that would be supersede Void Linux in the near future.

Operating Systems and Porting / ASpeed DRM Driver Adding DMA-BUF/PRIME Sharing For Use With Servers Having dGPUs

« on: August 31, 2022, 04:10:49 am »

"This patch is designed to solve the problem that the AST is not displayed when the server plug in a discrete graphics card at the same time. We call the dirty callback function to copy the rendering results of the discrete graphics card to the ast side by dma-buf."

Applications and Porting / [Games] Cosmo Cosmic adventure

« on: August 23, 2022, 01:06:04 am »

The cosmo engine project provides an alternative engine to run assets of the original DOS game Cosmo Cosmic adventure.

There is a bug with SDL_free which causes memory leak segfault. Simply replace `SDL_free` with `free` and the game would run nicely.

Applications and Porting / [GAMES] Ultimate Doom with all enhancements on crispy-doom client

« on: August 22, 2022, 06:59:44 pm »

There are countless of Doom1 clients on the net but only one that really strike the balance between the classic gameplay and modern QoL is the crispy-doom.

Crispy doom is based on Chocolate Doom with enhancments:

* Large screen resolution with different ratio aspect
* Jump / Free look mouse movement (just like modern FPS)
* Lots and lots of QoL options

The client can be compiled successfully for ppc64le without additional changes.

FYI The Ultimate DOOM Wad could be found on archive.org

Operating Systems and Porting / [DEV] Testing out Fedora 37

« on: August 22, 2022, 08:26:37 am »

Fedora 37 looks very promising. The 5.19 kernel is still buggy at the time of this writing so I fallback to the 5.18.17 (of Fedora 36). The 5.19.3-300 runs perfectly fine now

My first impression is how MUCH MORE responsive mutter of GNOME 43 has become. The GNOME shell is quite snappy just like of the old days of GNOME 3.38.

Many apps have been ported to GTK4 and libadwaita and I expect more apps to follow in the GNOME 44.
