Implements basic ASTC support:
* Only 4x4 and 8x8 block sizes.
* Other block sizes are too complex to handle for Godot image compression handling. May be implemented sometime in the future.
The need for ASTC is mostly for the following use cases:
* Implement a high quality compression option for textures on mobile and M1 Apple hardware.
* For this, the 4x4 is sufficient, since it uses the same size as BPTC.
ASTC supports a lot of block sizes, but the benefit of supporting most of them is slim, while the implementation complexity in Godot is very high.
Supporting only 4x4 (and 8x8) solves the real problem, which is lack of a BPTC alternative on hardware where it's missing.
Note: This does not yet support encoding on import, an ASTC encoder will need to be added.
Replace all TODO uses of `#warning` by proper TODO comments, and will open
matching bug reports to keep track of them.
We don't have a great track record fixing TODOs, but I'd wager we're even
worse for fixing these "TODO #warning" so we should prohibit this usage.
Mainly:
- Make `max_descriptors_per_pool` project setting Vulkan-specific.
- Use a common, render driver agnostic magic FourCC for shader binary data.
- Downgrade spirv_reflect to Vulkan-only dependency.
- Add a `RENDER_DRIVER_*` macro to GLSL shader code for per-driver customizations.
Adds a FramebufferCache singletion that operates the same way as UniformSetCache.
Allows creating framebuffers on the fly (and keep them cached if re-requested) such as:
```C++
RID fb = FramebufferCache::get_singleton()->get_cache(texture1,texture2);
```
- Validate format conservatively. (This is to have VRS images created regardless whether VRS attachments are supported, which avoids errors in places where the code assumes such images were created on low-spec GPUs.)
- Create a non-layered default VRS image, which is what Vulkan (and D3D12, by the way) expect.
- Check block decoration in addition to type decoration to be sure to find `readonly` decorators
- Verify uniforms have same writability across all shader stages in Vulkan RD
- Include Godot version and commit hash in shader cache key
- Reject files when format doesn't match, even if it's lower, since we don't have backwards compatibility here
- Initialize queue indices to values meaning 'unset'
- Remove unused parameters & members
- Make texture update access flags consistent with texture copy
- Fix style and pass type of some parameters
- Synchronize setup-draw in flush with a semaphore
- Add no current list validation to draw_list_begin_splits()
- Update texture usage flags on destination of copy
- Fix misuse of Vulkan flag
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
This method can be used to get the graphics API version currently in
use (such as Vulkan). It can be used by projects for troubleshooting
or statistical purposes.
This commit removes a lot of enum values related to the color render pass in favor of a new flag-bases approach. This means instead of hard-coding all the possible option combinations into enums, we can write our logic by checking a bit-mask.
The changes in rendering_device_vulkan.cpp add support for unused attachments. That means RenderingDeviceVulkan::framebuffer_create() can take null RIDs in the attachments vector, which will result in VK_ATTACHMENT_UNUSED entries in the render pass.
This is used in this same PR to establish fixed locations for the color pass attachments (only color and separate specular so far, but TAA will add motion vectors as well). This way the attachment locations in the shader can stay the same regardless of which attachments are actually used.
Right now all the combinations of flags are generated, but we will need to add a way to limit the amount of combinations in the future.
* Changed syntax usage for RD::Uniform to create faster with a single RID
* Converted render pass setup to use this in clustered renderer to test.
This is the first step into creating a proper uniform set cache system to simplify large parts of the codebase.
This updates VMA and instead of using the custom small pool approach from 4e6c9d3ae9, lazily creates pools for the relevant memory type indices, which doesn't require patching VMA.
Also, patches already merged upstream or not needed any longer are removed.
On the only platform where PVRTC is supported (iOS),
ETC2 generally supersedes PVRTC in every possible way. The increased
memory usage is not really a problem thanks to modern iOS' devices
processing power being higher than its Android counterparts.

This can be used to distinguish between integrated, dedicated, virtual
and software-emulated GPUs. This in turn can be used to automatically
adjust graphics settings, or warn users about features that may run
slowly on their hardware.
Sets `AlignOperands` to `DontAlign`.
`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
