How can mimalloc manage a piece of allocated memory?

6

I have already allocated a piece of big memory by `mmap`, the memory size (as `MEM_SIZE`) is large, so I want to use it as a memory pool, or a...

I'm currently evaluating using mimalloc as libc allocator in Chimera Linux (https://chimera-linux.org). Currently, we have LLVM's Scudo integrated into our libc but testing shows that mimalloc may be a better...

Performance differences between Windows and Linux

I've been running our software through our benchmark suite with both mimalloc 1.8.7 and mimalloc 2.1.7 and have noticed some differences in its behaviour across OSes. On Windows, 2.1.7 pretty...

High virtual memory usage, reset_decommits doesn't work

Hi! I'm evaluating using mimalloc-secure 2.0.3 for our game instead of Unreal Engine's default FMallocBinned2. The runtime performance seems good, I have not measured any significant regression from this switch....

vcpkg produces `mimalloc.dll` when building `mimalloc[override]` and minject is not supporting that name. Can we change behaviour of `--postfix=` so it would use `mimalloc.dll` instead of `mimalloc-.dll`

memory decommit does not work with large pages

2

Seems that mimalloc does not decommit memory that was comitted using large pages. See https://github.com/microsoft/mimalloc/blob/03020fbf81541651e24289d2f7033a772a50f480/src/arena.c#L540 and https://github.com/microsoft/mimalloc/blob/03020fbf81541651e24289d2f7033a772a50f480/src/arena.c#L832 what's the motivation behind this? why large pages can not be decomitted?

Inconsistent output naming of `mimalloc.dll`

7

After updating to `v2.1.7`, `mimalloc-redirect.dll` requires `mimalloc-override.dll`. While this is consistent with readme instruction, the names of the DLL objects after compiling are still `mimalloc.dll` and `mimalloc-redirect.dll` inside the build...
