I have a mixed feeling with patterns. I like them, but BDW times showed they get sometimes hidden hence forgotten so it is hard to maintain. Anyway, defining as ITS_OWN_PLATFORM_ULX and them embedded them here or using there directly on the code NEW_ULX || KBL_ULX is desired. Otherwise if we define here inside KBL ULX we might thing this is KBL. :/ > > > #define IS_SKL_GT2(dev_priv) (IS_SKYLAKE(dev_priv) && \ > > (dev_priv)->info.gt == 2) > > #define IS_SKL_GT3(dev_priv) (IS_SKYLAKE(dev_priv) && \ _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
