Subject: [Intel-gfx] [PATCH 30/46] drm/i915/guc: Implement no mid batch preemption for multi-lrc
Date: Tue, 3 Aug 2021 15:29:27 -0700 [thread overview]
Message-ID: <20210803222943.27686-31-matthew.brost@intel.com> (raw)
In-Reply-To: <20210803222943.27686-1-matthew.brost@intel.com>
For some users of multi-lrc, e.g. split frame, it isn't safe to preempt
mid BB. To safely enable preemption at the BB boundary, a handshake
between to parent and child is needed. This is implemented via custom
emit_bb_start & emit_fini_breadcrumb functions and enabled via by
default if a context is configured by set parallel extension.
