Subject: [Intel-gfx] [PATCH v2 08/12] drm/i915: finish removal of gen_mask
Date: Mon, 12 Apr 2021 22:09:58 -0700	[thread overview]
Message-ID: <20210413051002.92589-9-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20210413051002.92589-1-lucas.demarchi@intel.com>

Now that it's not used anywhere, remove it from struct
intel_device_info. To allow a period in which code will be converted to
the new macro, keep IS_GEN_RANGE() around, just redefining it to use
the new fields. The size advantage from IS_GEN_RANGE() using a mask is
not that big as it has pretty limited use througout the driver:
