Subject: [Intel-gfx] [PATCH 10/12] drm/i915/guc: Support larger contexts on newer hardware
Date: Tue, 12 Jul 2022 16:31:34 -0700	[thread overview]
Message-ID: <20220712233136.1044951-11-John.C.Harrison@Intel.com> (raw)
In-Reply-To: <20220712233136.1044951-1-John.C.Harrison@Intel.com>

From: Matthew Brost <matthew.brost@intel.com>

The GuC needs a copy of a golden context for implementing watchdog
resets (aka media resets). This context is larger on newer platforms.
So adjust the size being allocated/copied accordingly.
