PR #90993 added several debugging utilities.
Among them, advanced memory tracking through the use of custom
allocators and VK_EXT_device_memory_report.
However as issue #95967 reveals, it is dangerous to leave it on by
default because drivers (or even the Vulkan loader) can too easily
accidentally break custom allocators by allocating memory through std
malloc but then request us to deallocate it (or viceversa).
This PR fixes the following problems:
- Adds --extra-gpu-memory-tracking cmd line argument
- Adds missing enum entries to
RenderingContextDriverVulkan::VkTrackedObjectType
- Adds RenderingDevice::get_driver_and_device_memory_report
- GDScript users can easily check via print(
RenderingServer.get_rendering_device().get_driver_and_device_memory_report()
)
- Uses get_driver_and_device_memory_report on device lost for appending
further info.
Fixes#95967
Features:
- Debug-only tracking of objects by type. See
get_driver_allocs_by_object_type et al.
- Debug-only Breadcrumb info for debugging GPU crashes and device lost
- Performance report per frame from get_perf_report
- Some VMA calls had to be modified in order to insert the necessary
memory callbacks
Functionality marked as "debug-only" is only available in debug or dev
builds.
Misc fixes:
- Early break optimization in RenderingDevice::uniform_set_create
============================
The work was performed by collaboration of TheForge and Google. I am
merely splitting it up into smaller PRs and cleaning it up.
Enables support for enhanced barriers if available.
Gets rid of the implementation of [CROSS_FAMILY_FALLBACK] in the D3D12 driver. The logic has been reimplemented at a higher level in RenderingDevice itself.
This fallback is only used if the RenderingDeviceDriver reports the API traits and the capability of sharing texture formats correctly. Aliases created in this way can only be used for sampling: never for writing. In most cases, the formats that do not support sharing do not support unordered access/storage writes in the first place.
* Replaces `find(...) != -1` with `contains` for `String`
* Replaces `find(...) == -1` with `!contains` for `String`
* Replaces `find(...) != -1` with `has` for containers
* Replaces `find(...) == -1` with `!has` for containers
It used to warn when opening a new project because no cache pre-exists,
which isn't particularly helpful.
Also include the rendering method in the cache filename, as it differs
between Forward+ and Mobile for a same GPU.
* Do not print empty line when header is disabled
* Do not print Vulcan header
* Also add "Print header" project setting (default On)
(suggested by @kaissouDev)
* Add docs for the project setting
(with suggestions by @Mickeon and @akien-mga)
