Subject: [PATCH] Backport AMD external-memory view ownership fix to ROCm 7.2
|
|
|
|
Upstream fix: ROCm/clr 529f6b1641de436dafbb095d5438b0fbf773765d
|
|
(ROCm/rocm-systems #3528). Already present in current upstream.
|
|
The constructor owns reference 1. MemObjMap does not retain the view;
|
|
hipFree removes the entry and releases reference 1. The extra retain
|
|
leaks the view and its parent imported allocation.
|
|
|
|
Hardware regression: d4r_d3d12_hip_interop_probe --interop-mode map
|
|
--iterations 64. Windows SDK 7.2.60201 leaks one HANDLE / 256 KiB each
|
|
cycle; tested TheRock 10.2.0a20260929 (HIP 7.17.26386) stays bounded.
|
|
This patch is for rebuilding old runtime sources, never binary patching.
