The only difference for the more recent of those macros is the version of the *_reg_<read/write>_fw_domains function. Passing the function prefix in allows us to re-use the same macro to generate functions for different GENs and will make it easier to add new accessors in the futureCc: Tvrtko Ursulin <tvrtko.ursu...@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospu...@intel.com> --- drivers/gpu/drm/i915/intel_uncore.c | 40 ++++++++++--------------------------- 1 file changed, 10 insertions(+), 30 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_uncore.c b/drivers/gpu/drm/i915/intel_uncore.c index 3d243fe..1ff8fd9 100644 --- a/drivers/gpu/drm/i915/intel_uncore.c +++ b/drivers/gpu/drm/i915/intel_uncore.c @@ -992,29 +992,19 @@ static inline void __force_wake_auto(struct drm_i915_private *dev_priv, ___force_wake_auto(dev_priv, fw_domains); } -#define __gen6_read(x) \ +#define __gen_read(func, x) \ static u##x \ -gen6_read##x(struct drm_i915_private *dev_priv, i915_reg_t reg, bool trace) { \ +func##_read##x(struct drm_i915_private *dev_priv, i915_reg_t reg, bool trace) { \ enum forcewake_domains fw_engine; \ GEN6_READ_HEADER(x); \ - fw_engine = __gen6_reg_read_fw_domains(offset); \ - if (fw_engine) \ - __force_wake_auto(dev_priv, fw_engine); \ - val = __raw_i915_read##x(dev_priv, reg); \ - GEN6_READ_FOOTER; \ -} - -#define __fwtable_read(x) \ -static u##x \ -fwtable_read##x(struct drm_i915_private *dev_priv, i915_reg_t reg, bool trace) { \ - enum forcewake_domains fw_engine; \ - GEN6_READ_HEADER(x); \ - fw_engine = __fwtable_reg_read_fw_domains(offset); \ + fw_engine = __##func##_reg_read_fw_domains(offset); \ if (fw_engine) \ __force_wake_auto(dev_priv, fw_engine); \ val = __raw_i915_read##x(dev_priv, reg); \ GEN6_READ_FOOTER; \ } +#define __gen6_read(x) __gen_read(gen6, x) +#define __fwtable_read(x) __gen_read(fwtable, x) #define __gen9_decoupled_read(x) \ static u##x \ @@ -1115,29 +1105,19 @@ static inline void __force_wake_auto(struct drm_i915_private *dev_priv, GEN6_WRITE_FOOTER; \ } -#define __gen8_write(x) \ +#define __gen_write(func, x) \ static void \ -gen8_write##x(struct drm_i915_private *dev_priv, i915_reg_t reg, u##x val, bool trace) { \ +func##_write##x(struct drm_i915_private *dev_priv, i915_reg_t reg, u##x val, bool trace) { \ enum forcewake_domains fw_engine; \ GEN6_WRITE_HEADER; \ - fw_engine = __gen8_reg_write_fw_domains(offset); \ - if (fw_engine) \ - __force_wake_auto(dev_priv, fw_engine); \ - __raw_i915_write##x(dev_priv, reg, val); \ - GEN6_WRITE_FOOTER; \ -} - -#define __fwtable_write(x) \ -static void \ -fwtable_write##x(struct drm_i915_private *dev_priv, i915_reg_t reg, u##x val, bool trace) { \ - enum forcewake_domains fw_engine; \ - GEN6_WRITE_HEADER; \ - fw_engine = __fwtable_reg_write_fw_domains(offset); \ + fw_engine = __##func##_reg_write_fw_domains(offset); \ if (fw_engine) \ __force_wake_auto(dev_priv, fw_engine); \ __raw_i915_write##x(dev_priv, reg, val); \ GEN6_WRITE_FOOTER; \ } +#define __gen8_write(x) __gen_write(gen8, x) +#define __fwtable_write(x) __gen_write(fwtable, x) #define __gen9_decoupled_write(x) \ static void \
