Another link I raised: https://issuetracker.google.com/issues/330066232

Version: From Android 14
Reproduce: AOSP build with x86_64, run with

$ ./VtsHalNeuralnetworksTargetTest --gtest_filter=TestGenerated/MemoryDomainTest.Test/android_hardware_neuralnetworks_IDevice_nnapi_sample_all_conv_quant8

then you will get error message like bellow

[  FAILED  ] TestGenerated/MemoryDomainTest.Test/android_hardware_neuralnetworks_IDevice_nnapi_sample_all_conv_quant8, where GetParam() = (("android.hardware.neuralnetworks.IDevice/nnapi-sample_all", (ptr = 0x72c3ff208300, value = 32-byte object <48-9B B9-2F 63-56 00-00 FF-FF FF-FF FF-FF FF-FF 00-83 20-FF C3-72 00-00 90-52 1C-FF C4-72 00-00>)), ("conv_quant8", 0x56632fbaa0c0)) (91 ms)
[----------] 1 test from TestGenerated/MemoryDomainTest (97 ms total)

Why it failed from Android 14 as I described in https://issuetracker.google.com/issues/330066232, from Android14, goldfish-opengl AHardwareBuffer_lock() implementation is changed, once cb->lockedUsage is non-zero, it will reture error code. source code: device/generic/goldfish-opengl/system/hals/mapper3.cpp

However, in VTS GeneratedTestHarness.cpp MemoryDomain test, TestBlobAHWB object once is created, it will map(), then lock buffer in map() till testcase is end. If buffer is always lock, how vendor device get AHardwareBuffer virtual memory pointer. I check frameworks/native/libs/nativewindow/include/android/hardware_buffer.h, which seems I can only get virtual memory by AHardwareBuffer_lock(), if it is locked by TestBlobAHWB object, AHardwareBuffer_lock() returns fail.
So I don't know how to get virtual pointer of CPU buffer.
Looking forward to your reply, thanks.
