This is an official documentation for file format used by Vulkan Memory Allocator library
|
||||
to record and replay sequence of calls to its functions.
|
||||
This feature can be enabled by using `VmaAllocatorCreateInfo::pRecordSettings` structure members.
|
||||
For details, see main documentation of the library.
|
||||
Playback can be launched using **VmaReplay** console application.
|
||||
|
||||
Recording is a text file.
|
||||
Line endings: Unix `'\n'`.
|
||||
Character encoding: single-byte (can be ASCII or UTF-8, whaterver you use in custom strings).
|
||||
Suggested file extension: **csv**. File can be processed sequentially - no random access is needed.
|
||||
Each line forms a separate entry.
|
||||
Each line consists of a set of values (also called columns), separated by comma `','` (hence "CSV" format - Comma Separated Values).
|
||||
Number of columns is different in different lines.
|
||||
|
||||
# Header
|
||||
|
||||
First line identifies file format. It must always be:
|
||||
|
||||
Vulkan Memory Allocator,Calls recording
|
||||
|
||||
Second line identifies format version, where first column is major version and second column is minor version.
|
||||
Formats with only minor version incremented are backward compatible.
|
||||
VmaReplay application supports all older versions.
|
||||
Current version is:
|
||||
|
||||
1,2
|
||||
|
||||
# Function calls
|
||||
|
||||
Remaining lines contain recorded calls to VMA functions. First columns are always:
|
||||
|
||||
- Thread ID : uint32
|
||||
- Time since first call : float, in seconds
|
||||
- VMA frame index : uint32
|
||||
- Function name : string
|
||||
|
||||
Remaining columns are function parameters and output, depending on function name, which can be:
|
||||
|
||||
**vmaCreateAllocator, vmaDestroyAllocator**
|
||||
|
||||
No parameters.

## Data types
|
||||
|
||||
**bool**
|
||||
|
||||
Encoded as `0` for false or `1` for true.
|
||||
|
||||
**uint32, uint64**
|
||||
|
||||
Encoded in decimal format.
|
||||
|
||||
**pointer**
|
||||
|
||||
Encoded in hexadecimal format.
|
||||
|
||||
**pUserData**
|
||||
|
||||
If `pUserData` was a pointer, it is encoded as hexadecimal string.
|
||||
If `VMA_ALLOCATION_CREATE_USER_DATA_COPY_STRING_BIT` was used with the allocation, the string is written as-is.
|
||||
It may contain additional commas.
|
||||
It should not contain end-of-line characters - results are then undefined.

Functions <code>vkMapMemory()</code>, <code>vkUnmapMemory()</code> are designed for this purpose. You can use them directly with memory allocated by this library, but it is not recommended because of following issue: Mapping the same <code>VkDeviceMemory</code> block multiple times is illegal - only one mapping at a time is allowed.
