From 2446e1d6433b4b99d69e8fe0522bcdfbdef715b5 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Wed, 7 Apr 2021 13:39:45 -0700 Subject: drm/i915/display: Eliminate IS_GEN9_{BC,LP} MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that we've eliminated INTEL_GEN(), IS_GEN_RANGE(), etc. from the display code, we should also kill off our use of the IS_GEN9_* macros too. We'll do the conversion manually this time instead of using Coccinelle since the most logical substitution can depend heavily on the code context, and sometimes we can keep the code simpler if we make additional adjustments such as swapping the order of if/else arms. v2: - Restore a lost negation in intel_pll_is_valid().

If we remove the current users of IS_DISPLAY_VER(), we could actually repurpose it for a range check With (1) there could be an advantage if we used gen_mask since multiple conditionals be combined by the compiler in a single and instruction and check the result. However a) INTEL_GEN() doesn't use the mask since it would make the code bigger everywhere else and b) in the cases it made sense, it also made sense to convert to the _RANGE() variant. So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER() users to use == and != operators. Aside from the definition changes, this was done by the following semantic patch: @@ expression dev_priv, E1; @@ - !IS_DISPLAY_VER(dev_priv, E1) + DISPLAY_VER(dev_priv) != E1 @@ expression dev_priv, E1;
