Subject: [Intel-gfx] [PATCH v2 05/50] drm/i915/selftests: Allow for larger engine counts
Date: Tue, 13 Jul 2021 20:14:55 -0700 [thread overview]
Message-ID: <20210714031540.3539704-6-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210714031540.3539704-1-matthew.d.roper@intel.com>
From: John Harrison <John.C.Harrison@Intel.com>
Increasing the engine count causes a couple of local array variables
to exceed the kernel stack limit. So make them dynamic allocations
instead.
