From fae1267df8a14140544204c65258867d72f287bb Mon Sep 17 00:00:00 2001 From: Pradeep Bhat Date: Tue, 4 Nov 2014 17:06:39 +0000 Subject: [PATCH] drm/i915/skl: Register definitions and macros for SKL Watermark regs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This patch defines SKL specific PLANE_WM Watermark registers. It also defines macros to get the addresses of different LP levels within a pipe. v2: Reworked the register definitions and associated macros to make it more generic and be able to use for_each_pipe in values computation. Incorporated Damien's review comments and indentation. v3: Added default values for lines and blocks. Provided mask for blocks. v4: Prefix intermedidate (internal-only) macros with _ (Ville) v5: Remove the lines and block defaults value (Ville) Reviewed-by: Ville Syrjälä (v4) Signed-off-by: Pradeep Bhat Signed-off-by: Damien Lespiau Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_reg.h | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index db7d8fd..ccbaeb3 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -4102,6 +4102,41 @@ enum punit_power_well { #define I965_CURSOR_MAX_WM 32 #define I965_CURSOR_DFT_WM 8 +/* Watermark register definitions for SKL */ +#define CUR_WM_A_0 0x70140 +#define CUR_WM_B_0 0x71140 +#define PLANE_WM_1_A_0 0x70240 +#define PLANE_WM_1_B_0 0x71240 +#define PLANE_WM_2_A_0 0x70340 +#define PLANE_WM_2_B_0 0x71340 +#define PLANE_WM_TRANS_1_A_0 0x70268 +#define PLANE_WM_TRANS_1_B_0 0x71268 +#define PLANE_WM_TRANS_2_A_0 0x70368 +#define PLANE_WM_TRANS_2_B_0 0x71368 +#define CUR_WM_TRANS_A_0 0x70168 +#define CUR_WM_TRANS_B_0 0x71168 +#define PLANE_WM_EN (1 << 31) +#define PLANE_WM_LINES_SHIFT 14 +#define PLANE_WM_LINES_MASK 0x1f +#define PLANE_WM_BLOCKS_MASK 0x3ff + +#define CUR_WM_0(pipe) _PIPE(pipe, CUR_WM_A_0, CUR_WM_B_0) +#define CUR_WM(pipe, level) (CUR_WM_0(pipe) + ((4) * (level))) +#define CUR_WM_TRANS(pipe) _PIPE(pipe, CUR_WM_TRANS_A_0, CUR_WM_TRANS_B_0) + +#define _PLANE_WM_1(pipe) _PIPE(pipe, PLANE_WM_1_A_0, PLANE_WM_1_B_0) +#define _PLANE_WM_2(pipe) _PIPE(pipe, PLANE_WM_2_A_0, PLANE_WM_2_B_0) +#define _PLANE_WM_BASE(pipe, plane) \ + _PLANE(plane, _PLANE_WM_1(pipe), _PLANE_WM_2(pipe)) +#define PLANE_WM(pipe, plane, level) \ + (_PLANE_WM_BASE(pipe, plane) + ((4) * (level))) +#define _PLANE_WM_TRANS_1(pipe) \ + _PIPE(pipe, PLANE_WM_TRANS_1_A_0, PLANE_WM_TRANS_1_B_0) +#define _PLANE_WM_TRANS_2(pipe) \ + _PIPE(pipe, PLANE_WM_TRANS_2_A_0, PLANE_WM_TRANS_2_B_0) +#define PLANE_WM_TRANS(pipe, plane) \ + _PLANE(plane, _PLANE_WM_TRANS_1(pipe), _PLANE_WM_TRANS_2(pipe)) + /* define the Watermark register on Ironlake */ #define WM0_PIPEA_ILK 0x45100 #define WM0_PIPE_PLANE_MASK (0xffff<<16) -- 2.7.4
