From 695ec62187ba0708e3f8a960c2b75b877c2521a9 Mon Sep 17 00:00:00 2001 From: Daniel Phillips Date: Fri, 3 Mar 2023 15:01:03 -0800 Subject: [PATCH] kfdtests: Relax MemoryAllocAll failure criteria The MemoryAllocAll test in kfdtests exercises the new KFD memory availability API by trying to allocate a single buffer object that exactly fills all of vram. Desired object size is determined using the memory availility KFD ioctl via libhsakmt, then an object is allocated slightly larger than that size. If the allocation attempt fails then the test tries to allocate a slightly smaller object, and continues trying with smaller sizes until the allocation succeeds. The test succeeds if the successfully allocated object is within some specified tolerance of the available memory reported. There are a number of known issues that can cause the successfully allocated object to be significantly smaller than reported availability. Until these issues are addressed, we should not fail the test, but just log the actual divergence between the size of the object we thought we could allocate, and what was actually possible.
