* [Intel-gfx] [PATCH i-g-t] i915/gem_exec_schedule: Try to spot unfairness

An important property for multi-client systems is that each client gets
a 'fair' allotment of system time. (Where fairness is at the whim of the
context properties, such as priorities.) This test forks N independent
clients (albeit they happen to share a single vm), and does an equal
amount of work in client and asserts that they take an equal amount of
time.
Though we have never claimed to have a completely fair scheduler, that
is what is expected.

* [igt-dev] [PATCH i-g-t] i915/gem_exec_schedule: Try to spot unfairness
@ 2020-06-22 19:08 ` Chris Wilson
0 siblings, 0 replies; 4+ messages in thread
From: Chris Wilson @ 2020-06-22 19:08 UTC (permalink / raw)
To: intel-gfx; +Cc: igt-dev, Tvrtko Ursulin, Chris Wilson
An important property for multi-client systems is that each client gets
a 'fair' allotment of system time. (Where fairness is at the whim of the
context properties, such as priorities.) This test forks N independent
clients (albeit they happen to share a single vm), and does an equal
amount of work in client and asserts that they take an equal amount of
time.
Though we have never claimed to have a completely fair scheduler, that
is what is expected.
