The only usage outside the intel_lrc.c file is in the ringbuffer init, but the irq mask calculated there is then overwritten for all engines that have a non-zero shift, so we can drop it. This change is not aimed at code saving but at removing from intel_engines information that does not apply to all gens that have the engine. When checking without the temporary WARN_ON, code size is basically unchanged. v2: make the irq_shifts array static const v3: rebase, move irq_shifts array to logical_ring_default_irqs v4: move array inside the if and use u8 for it (Chris) Suggested-by: Michel Thierry <michel.thierry@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20180314182653.26981-4-daniele.ceraolospurio@intel.com |
