Subject: [Intel-gfx] [PATCH 30/47] drm/i915/guc: Direct all breadcrumbs for a class to single breadcrumbs
Date: Thu, 24 Jun 2021 00:04:59 -0700	[thread overview]
Message-ID: <20210624070516.21893-31-matthew.brost@intel.com> (raw)
In-Reply-To: <20210624070516.21893-1-matthew.brost@intel.com>

With GuC virtual engines the physical engine which a request executes
and completes on isn't known to the i915. Therefore we can't attach a
request to a physical engines breadcrumbs. To work around this we create
a single breadcrumbs per engine class when using GuC submission and
direct all physical engine interrupts to this breadcrumbs.
