VkFence and VkSemaphore synchronization primitives are deprecated. Going to switch over to vulkan timeline semaphores.

Also still determining whether to use Vulkan Sync Objects or external.

This is for better resource reuse

I haven't had a chance to check if this works (Followed vulkan-tuturial to write those portions of the code) [vkcomp/setup.c, vkcomp/display.c] are the exact files. Because I'm dumping the pixels to a Wayland Client surface that is currently not configured to handle that.

Most likely a math or logic error in custom memory manager.

DRM/KMS examples work fine

Like I said in README I am still new. Believe this is something that should be implement so that the shader can freely access resources like buffers and images.

Not all device queues are supported yet in lucurious.

Still need to add more useful output to command line tool. Makes it easier to develop.

I have the API set up. Just need to make sure all the right parameters are being passed in spin square test.

Invalid VkDescriptorSetLayout object. pSetLayouts must be a valid pointer to an array of descriptorSetCount valid VkDescriptorSetLayout handles.

Somewhere in test-image-texture.c the handles are being messed up.

Going to create gbm_bo and handle the presentation myself.

VkDisplayPropertiesKHR *pProperties;
vkGetPhysicalDeviceDisplayPropertiesKHR()

This needs to be implemented for all struct pointer members. As the amount of malloc/calloc/realloc calls cost to much for the operating system to consistently do. It will probably be better to allocate the space once and just use the same memory. Kind of like a Memory Pool.

Currently in lucurious all Vk Structs pNext members are set to NULL. Most flag members in lucurious are set to zero, aware that the vulkan API specifies that is must be zero for a number of flag members, but eventually want to add more functionality for flags.

Usage of struct member provides extra functionality.

This needs updating. May remove gp folder and header, need to figure out best way to rearrange this.

Here: https://github.com/EasyIP2023/lucurious/blob/development/src/display/meson.build#L28

systemd only exists on Linux, or even only on certain Linus distros. It doesn't exist for example on BSDs.

Please make it optional, since it shouldn't be a hard dependency.

Design Goals

• Speed
• Robustness
• lucurious users convenience

I want to update this particular function to have better output when vk* functions error out.

I want to allow for preferred selection of a KMS node if they so choose to. If not default to searching for a DRM device ourselves.

Having issues in test-rotate-rect.c. I thought that vkAcquireNextImageKHR changes the state of the semaphore. Then vkqueuesubmit changes it back. Help wanted

KMS atomic modesetting

Having an issue when doing operations (i.e. vkDestroySemaphore) further down the road when I free a sub allocated block.

There are already people working on Vulkan Wayland Compositors. It would be cool to implement wlroots into lucurious. Still learning Vulkan and Wayland so currently don't know.

swaywm/wlroots#642

Use global s to help limit the size of a given function call

This fine for now, but eventually needs to be change. Maybe figure out how to allocate physical pages myself.

Implement input handling with libinput.so

Not sure why yet.

Using gdb to investigate more.

I may not need to implement this..

Need to remove stb

There should be a an image on the screen that rotates and can be manipulated. Help much appreciated.
