From: Gustavo Sousa Date: Fri, 20 Jan 2023 18:14:23 +0000 (-0300) Subject: drm/i915/gt: Convert PSS_MODE2 to multicast register X-Git-Tag: v6.6.7~1918^2~16^2~326 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=41badc016c5b0c4a4be22292bf64ad9a3022a848;p=platform%2Fkernel%2Flinux-starfive.git drm/i915/gt: Convert PSS_MODE2 to multicast register That register became a multicast register as of Xe_HP and it is currently used only for DG2. Use a proper prefix since there could be usage of the same register for previous platforms in the future, which would require a different definition (i.e. using _MMIO). Note that, in its current state, the code does not cause functional problems, since the actual application of the workaround would implicitly use multicast mode. This fix is more toward consistency and being future-proof uses of this register outside of workarounds. v2: - Add paragraph noting that this change is for consistency and making the code future-proof.
