Allow to open other cards out of order with __drm_open_driver_another()
and also introduce helper for multi-gpu scenarios. There is still a problem
left when opening first device because it is useally already opened at
first fixture but I will leave that for later. With that it works
on four GPUs board, when first card is non-Intel one with no render
device:
sudo IGT_DEVICE=pci:vendor=Intel,device=discrete,card=all build/tests/xe_create --r multigpu-create-massive-size
Opened device: /dev/dri/card1
Starting subtest: multigpu-create-massive-size
<g:1> Opened device: /dev/dri/card2
<g:2> Opened device: /dev/dri/card3
<g:3> Opened device: /dev/dri/card4
Subtest multigpu-create-massive-size: SUCCESS (0.209s)
v3: fixes in test (Zbigniew)
fixes in drmlib functions (Zbigniew, Kamil)
v4: corrected test description (Kamil)
