gpu memory incorretly allocated using vgpu-memory-percentage resource name

[abowloflrf]

What happened:

I'm using volcano-vgpu-device-plugin with Volcano, when i'm trying to allocate vgpu with resource:

volcano.sh/vgpu-number: 1
volcano.sh/vgpu-cores: 50
volcano.sh/vgpu-memory-percentage: 20

The allocation results in Pod annotations show 0 memory was allocated, which is incorrect.

Volcano scheduler logs：

What you expected to happen:

The allocated memory should be totalMemory * percetage / 100 but not 0

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• Volcano Version: v1.8.2
• Kubernetes version (use kubectl version):
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:

'vgpu-memory-percentage' is not supported for volcano in this version, we plan to implement in the future
