[igt-dev] [PATCH i-g-t v1 0/4] drmtest changes for filtering GPUs on multi-gpu

[Kamil Konieczny <kamil.konieczny@linux.intel.com>]

Here is a proposed solution for multi-GPU testing with the help
of new drmtest functions. It will work with and without filters,
also when first card is non-Intel one with no render device.

sudo build/tests/xe_create --r multigpu-create-massive-size

sudo IGT_DEVICE=pci:vendor=Intel,device=discrete,card=all build/tests/xe_create --r multigpu-create-massive-size

IGT-Version: 1.28-g24b5fbcb5 (x86_64) (Linux: 6.6.0-rc3-xe-public-37b2d042c23a+ x86_64)
Opened device: /dev/dri/card1
Starting subtest: multigpu-create-massive-size
<g:0> Opened device: /dev/dri/card1
<g:1> Opened device: /dev/dri/card2
<g:2> Opened device: /dev/dri/card3
Subtest multigpu-create-massive-size: SUCCESS (0.202s)
