drm/i915/gt: Distinguish the virtual breadcrumbs from the irq breadcrumbs
On the virtual engines, we only use the intel_breadcrumbs for tracking signaling of stale breadcrumbs from the irq_workers. They do not have any associated interrupt handling, active requests are passed to a physical engine and associated breadcrumb interrupt handler. This causes issues for us as we need to ensure that we do not actually try and enable interrupts and the powermanagement required for them on the virtual engine, as they will never be disabled. Instead, let's specify the physical engine used for interrupt handler on a particular breadcrumb. v2: Drop b->irq_armed = true mocking for no interrupt HW Fixes: 4fe6abb8f513 ("drm/i915/gt: Ignore irq enabling on the virtual engines") Signed-off-by: Chris Wilson <[email protected]> Cc: Tvrtko Ursulin <[email protected]> Reviewed-by: Tvrtko Ursulin <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Rodrigo Vivi <[email protected]> Signed-off-by: Joonas Lahtinen <[email protected]>
