From 680d0c7960f12fc3852c70b2bab278cc5e70b88a Mon Sep 17 00:00:00 2001 From: Lucas De Marchi Date: Fri, 20 Jan 2023 11:34:52 -0800 Subject: [PATCH] drm/i915: Convert pll macros to _PICK_EVEN_2RANGES Avoid the array lookup, converting the PLL macros after ICL to _PICK_EVEN_RANGES. This provides the following reduction in code size: $ size build64/drivers/gpu/drm/i915/i915.o{.old,.new} text data bss dec hex filename 4027456 185703 6984 4220143 4064ef build64/drivers/gpu/drm/i915/i915.o.old 4026997 185703 6984 4219684 406324 build64/drivers/gpu/drm/i915/i915.o.new At the same time it's safer, avoiding out-of-bounds array access. This allows to remove _MMIO_PLL3() that is now unused.
