[igt-dev] [PATCH i-g-t 2/7] lib/igt_core: store GPU string or opened device name

[igt-dev] [PATCH i-g-t 2/7] lib/igt_core: store GPU string or opened device name

[Kamil Konieczny]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

This is helpful on tests that run with multiple GPUs.
The name will be automatically filled when a device will
be opened.

v2: reorganized code, changed commit message to note that
  it will be filled with pathname of opended device, also
  correct static initialization [Kamil]

This is assuming that multiple gpu usage is done from different
threads/processes per gpu. What about tests that call
drm_open_driver_another() from the same thread?

What about tests that don't call drm_open_driver() at all?

[igt-dev] [PATCH i-g-t 3/7] lib/igt_core: add prefix to logging

[Kamil Konieczny]

Allow to store prefix for logs and print it before any message.
This will allow to diagnose on wich GPU occurred problems when
tested on multi-GPU machines.

[igt-dev] [PATCH i-g-t 6/7] tests/i915/gem_exec_gttfill: add new subtest multigpu-basic

[Kamil Konieczny]

Add new subtest multigpu-basic to be run on two or more GPU cards
simultanosly. For this to work test should be run with --device
option, for example with:
  --device=pci:vendor=Intel,device=discrete,card=0\;pci:vendor=Intel,device=discrete,card=1
or
  --device=pci:vendor=Intel,device=discrete,card=all

Hmm... I would just do:

		gpu_count = igt_device_filter_count();

As it seems that you're just wanting to ensure that gpu_count
is >= 1 here...

... Yet, this is the only place where you use gpu_count. So, count <= 0
won't cause any troubles.
