So just expand the masks to cover all available bits, even if those are reserved on some generations. v2: Don't extend WM1_LP_SR_MASK so far, for the *future* Signed-off-by: Ville Syrjälä Reviewed-by: Paulo Zanoni Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 35c9d868b893..88f76714dba3 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -3251,11 +3251,11 @@ /* define the Watermark register on Ironlake */ #define WM0_PIPEA_ILK 0x45100 -#define WM0_PIPE_PLANE_MASK (0x7f<<16) +#define WM0_PIPE_PLANE_MASK (0xffff<<16) #define WM0_PIPE_PLANE_SHIFT 16 -#define WM0_PIPE_SPRITE_MASK (0x3f<<8) +#define WM0_PIPE_SPRITE_MASK (0xff<<8) #define WM0_PIPE_SPRITE_SHIFT 8 -#define WM0_PIPE_CURSOR_MASK (0x1f) +#define WM0_PIPE_CURSOR_MASK (0xff) #define WM0_PIPEB_ILK 0x45104 #define WM0_PIPEC_IVB 0x45200 @@ -3265,9 +3265,9 @@ #define WM1_LP_LATENCY_MASK (0x7f<<24) #define WM1_LP_FBC_MASK (0xf<<20) #define WM1_LP_FBC_SHIFT 20 -#define WM1_LP_SR_MASK (0x1ff<<8) +#define WM1_LP_SR_MASK (0x7ff<<8) #define WM1_LP_SR_SHIFT 8 -#define WM1_LP_CURSOR_MASK (0x3f) +#define WM1_LP_CURSOR_MASK (0xff) #define WM2_LP_ILK 0x4510c #define WM2_LP_EN (1<<31) #define WM3_LP_ILK 0x45110
