Move linux to new disk commands

Move linux to new disk with rsync:

rsync -avxHAXW --progress /<old disk mount point> /<new disk mount point> --exclude=/<old disk mount point>/dev --exclude=/<old disk mount point>/sys --exclude=/<old disk mount point>/proc --exclude=/<old disk mount point>/run

or with cp:

cp -afv /home/ /mnt/home/

Update /etc/fstab with new uuid by:

ls -l /dev/disk/by-uuid/

Restore grub:

grub-install /dev/xxx
update-grub2

Vulkan Software render (amd64+Windows)

There are small list of commands for compile Vulkan soft render library on amd64 debian, sequence is fully same as in the previous post related to check quake2 run on the arm64

git clone git@github.com:google/swiftshader.git
cd swiftshader/build
cmake ..
make -j 2 vk_swiftshader
sudo cp libvk_swiftshader.so /usr/lib/x86_64-linux-gnu/libvulkan_swiftshader.so
sed -i "s|./libvk_swiftshader.so|/usr/lib/x86_64-linux-gnu/libvulkan_swiftshader.so|g" Linux/vk_swiftshader_icd.json
sudo cp Linux/vk_swiftshader_icd.json /usr/share/vulkan/icd.d/swiftshader_icd.x86_64.json
sudo chmod 644 /usr/share/vulkan/icd.d/swiftshader_icd.x86_64.json
sudo chown root:root /usr/share/vulkan/icd.d/swiftshader_icd.x86_64.json
sudo chmod 644 /usr/lib/x86_64-linux-gnu/libvulkan_swiftshader.so
sudo chown root:root /usr/lib/x86_64-linux-gnu/libvulkan_swiftshader.so

And same story for Windows, It will be a little bit different story as result of different logic of package distribution. User have installed Vulkan drivers with Vulkan loader as part graphical drivers by default.

Compilation of code has required to install Vulkan SDK, CMake and Visual Studio.

And sequence of commands for build loader will be such for 64bit platform if no drivers installed with Vulkan.

git clone https://github.com/KhronosGroup/Vulkan-Loader.git
cd Vulkan-Loader/
cd external/
git clone https://github.com/google/googletest.git
git clone https://github.com/KhronosGroup/Vulkan-Headers.git
cd googletest
git checkout tags/release-1.8.1
cd ../..
mkdir build
cd build
cmake -A x64 --config Release ..
cmake --build . --config Release
cd ../..
Copy resulted library to C:\windows\System32 as vulkan-1.dll

Same commands but for 32 bit library

git clone https://github.com/KhronosGroup/Vulkan-Loader.git
cd Vulkan-Loader/
cd external/
git clone https://github.com/google/googletest.git
git clone https://github.com/KhronosGroup/Vulkan-Headers.git
cd googletest
git checkout tags/release-1.8.1
cd ../..
mkdir build
cd build
cmake -A win32 --config Release ..
cmake --build . --config Release
cd ../..
Copy resulted library to C:\windows\sysWOW64 as vulkan-1.dll

And then compile Vulkan driver for 64 platform:

git clone https://github.com/google/swiftshader.git
cd swiftshader/
git submodule init
cd third_party/
git clone https://github.com/google/googletest.git
git clone https://github.com/google/benchmark.git
git clone https://github.com/google/cppdap
git clone https://github.com/nlohmann/json.git
git clone https://github.com/ianlancetaylor/libbacktrace.git libbacktrace/src
cd ../build
cmake -A x64 --config Release ..
cmake --build . --config Release
cd ../..
Copy resulted file to preferred place, as example C:\Program Files\SwiftShaderVulkan

Same commands but for 32 bit library

git clone https://github.com/google/swiftshader.git
cd swiftshader/
git submodule init
cd third_party/
git clone https://github.com/google/googletest.git
git clone https://github.com/google/benchmark.git
git clone https://github.com/google/cppdap
git clone https://github.com/nlohmann/json.git
git clone https://github.com/ianlancetaylor/libbacktrace.git libbacktrace/src
cd ../build
cmake -A win32 --config Release ..
cmake --build . --config Release
cd ../..
Copy resulted file to preferred place, as example C:\Program Files\SwiftShaderVulkan

Also need to create ICD files like such C:\\Program Files\\SwiftShaderVulkan\\vk_swiftshader32.json with:

{
  "file_format_version": "1.0.0",
  "ICD": {
    "library_path": "C:\\Program Files\\SwiftShaderVulkan\\vk_swiftshader_32.dll",
    "api_version": "1.0.5"
  }
}

And C:\\Program Files\\SwiftShaderVulkan\\vk_swiftshader64.json with such content:

{
  "file_format_version": "1.0.0",
  "ICD": {
    "library_path": "C:\\Program Files\\SwiftShaderVulkan\\vk_swiftshader_64.dll",
    "api_version": "1.0.5"
  }
}

After that need to correctly register drivers, or,that will be less complicated, create reg file and apply such by RegEdit.

   
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Khronos\Vulkan\Drivers]
"C:\\Program Files\\SwiftShaderVulkan\\vk_swiftshader32.json"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\Drivers]
"C:\\Program Files\\SwiftShaderVulkan\\vk_swiftshader64.json"=dword:00000000

Vulkan Software render

Google have created software based Vulkan implementation sometime ago as not a official project.

And i have decided to check how it was in compare to other soft rendering implementations. And here are some results with yquake:

ref_gl1: 632 frames, 24.4 seconds: 25.9 fps (mesa 19.3.2 llvmpipe LLVM 9.0.1, 128 bits)
ref_gl3: 632 frames, 28.9 seconds: 21.9 fps (mesa 19.3.2 llvmpipe LLVM 9.0.1, 128 bits)
ref_soft: 632 frames, 10.9 seconds: 57.8 fps (mesa 19.3.2)
ref_vk: 632 frames, 98.9 seconds: 6.4 fps (SwiftShader Device LLVM 7.0.1)

Used steps for build SwiftShader are:

git clone git@github.com:google/swiftshader.git
cd swiftshader/build
CC="ccache gcc-8" CXX="ccache g++-8" cmake ..
CC="ccache gcc-8" CXX="ccache g++-8" make -j 2 vk_swiftshader
sudo cp libvk_swiftshader.so /usr/lib/aarch64-linux-gnu/libvulkan_swiftshader.so
sed -i "s|./libvk_swiftshader.so|/usr/lib/aarch64-linux-gnu/libvulkan_swiftshader.so|g" Linux/vk_swiftshader_icd.json
sudo cp Linux/vk_swiftshader_icd.json /usr/share/vulkan/icd.d/swiftshader_icd.aarch64.json
sudo chmod 644 /usr/share/vulkan/icd.d/swiftshader_icd.aarch64.json
sudo chown root:root /usr/share/vulkan/icd.d/swiftshader_icd.aarch64.json
sudo chmod 644 /usr/lib/aarch64-linux-gnu/libvulkan_swiftshader.so
sudo chown root:root /usr/lib/aarch64-linux-gnu/libvulkan_swiftshader.so

Note: Gcc 8 is preferred compiler for now as gcc-9 produced error with current version of code base.

Used steps for build yQuake2 are:

wget -cv https://deponie.yamagi.org/quake2/idstuff/q2-314-demo-x86.exe
unzip q2-314-demo-x86.exe
git clone git@github.com:yquake2/yquake2.git -b ref_vk
cd yquake2
make
cd ..
cp -rv Install/Data/baseq2/pak0.pak yquake2/release/baseq2/
cp -rv Install/Data/baseq2/players yquake2/release/baseq2

yquake2 7.42 version.

New version with speedup optimization in the software render.

Timedemo values (timedemo 1;) on 1280x800@60 with maps from quake2 demo are

7.20: 632 frames, 18.7 seconds: 33.8 fps

7.21: 632 frames, 19.1 seconds: 33.1 fps

7.30: 632 frames, 17.9 seconds: 35.4 fps

7.40: 632 frames, 17.5 seconds: 36.2 fps (36.8 fps)

7.41: 632 frames, 17.3 seconds: 36.5 fps

7.42: 632 frames, 17.0 seconds: 37.2 fps

Quake II 7.41 to 7.42:

The console can now be scrolled with the mouse wheel. (by maxcrofts)
Fix entities on non-horizontal surfaces rendered in full black.
Add an option to choose the display Quake II runs on. (by Spirrwell)
Add an option to specify the display refresh rate used in fullscreen.
Allow mouse 'sensitivity' to be set to non-integral values.
Port cvar operations from q2pro. These allow the manipulation of cvar values, supported are: dec, inc, reset, resetall and toggle
Put the client into pause mode during savegame load. This prevents the world getting forwarded about 100 frames during load, time in which the player might be hurt by monsters or the environment.
New commands: 'listentities' allows listing of entities. 'teleport' teleports the player to the given coordinates.
Fix loading of config files not ending in newlines.
A lot of fixes for subtle, long standing AI and game play bugs. (by BjossiAlfreds)
Quicksaves can now be loaded and saved throught the savegame menus.
The software render now skips frames with no changes. This improves performance quite a bit, especially on slow CPUs. (by Denis Pauk)
