From: Ben Widawsky Date: Wed, 29 May 2013 02:22:20 +0000 (-0700) Subject: drm/i915: Add VECS semaphore bits X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1950de14fd1b8ea27a411929156c7eccee2ad7c3;p=linux-beck.git drm/i915: Add VECS semaphore bits Like the other rings, the VECS supports semaphores. The semaphore stuff is a bit wonky so this patch on it's own should be nice for review. This patch should have no functional impact. v2: Fix the English parts of clarification (again, register names were right, text was reversed) (Damien) Restore the still valid invariant. (Damien) The bsd semaphore register should be MI_SEMAPHORE_SYNC_VVE (Damien) Signed-off-by: Ben Widawsky Reviewed-by: Damien Lespiau Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 19f8e51d2bdc..41c5d45362b2 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -265,13 +265,19 @@ #define MI_SEMAPHORE_UPDATE (1<<21) #define MI_SEMAPHORE_COMPARE (1<<20) #define MI_SEMAPHORE_REGISTER (1<<18) -#define MI_SEMAPHORE_SYNC_RB (0<<16) /* BCS wait for RCS (BRSYNC) */ -#define MI_SEMAPHORE_SYNC_RV (2<<16) /* VCS wait for RCS (VRSYNC) */ -#define MI_SEMAPHORE_SYNC_VR (0<<16) /* RCS wait for VCS (RVSYNC) */ -#define MI_SEMAPHORE_SYNC_VB (2<<16) /* BCS wait for VCS (BVSYNC) */ -#define MI_SEMAPHORE_SYNC_BV (0<<16) /* VCS wait for BCS (VBSYNC) */ -#define MI_SEMAPHORE_SYNC_BR (2<<16) /* RCS wait for BCS (RBSYNC) */ -#define MI_SEMAPHORE_SYNC_INVALID (1<<0) +#define MI_SEMAPHORE_SYNC_VR (0<<16) /* RCS wait for VCS (RVSYNC) */ +#define MI_SEMAPHORE_SYNC_VER (1<<16) /* RCS wait for VECS (RVESYNC) */ +#define MI_SEMAPHORE_SYNC_BR (2<<16) /* RCS wait for BCS (RBSYNC) */ +#define MI_SEMAPHORE_SYNC_BV (0<<16) /* VCS wait for BCS (VBSYNC) */ +#define MI_SEMAPHORE_SYNC_VEV (1<<16) /* VCS wait for VECS (VVESYNC) */ +#define MI_SEMAPHORE_SYNC_RV (2<<16) /* VCS wait for RCS (VRSYNC) */ +#define MI_SEMAPHORE_SYNC_RB (0<<16) /* BCS wait for RCS (BRSYNC) */ +#define MI_SEMAPHORE_SYNC_VEB (1<<16) /* BCS wait for VECS (BVESYNC) */ +#define MI_SEMAPHORE_SYNC_VB (2<<16) /* BCS wait for VCS (BVSYNC) */ +#define MI_SEMAPHORE_SYNC_BVE (0<<16) /* VECS wait for BCS (VEBSYNC) */ +#define MI_SEMAPHORE_SYNC_VVE (1<<16) /* VECS wait for VCS (VEVSYNC) */ +#define MI_SEMAPHORE_SYNC_RVE (2<<16) /* VECS wait for RCS (VERSYNC) */ +#define MI_SEMAPHORE_SYNC_INVALID (3<<16) /* * 3D instructions used by the kernel */ @@ -581,6 +587,7 @@ #define RENDER_RING_BASE 0x02000 #define BSD_RING_BASE 0x04000 #define GEN6_BSD_RING_BASE 0x12000 +#define VEBOX_RING_BASE 0x1a000 #define BLT_RING_BASE 0x22000 #define RING_TAIL(base) ((base)+0x30) #define RING_HEAD(base) ((base)+0x34) @@ -588,13 +595,20 @@ #define RING_CTL(base) ((base)+0x3c) #define RING_SYNC_0(base) ((base)+0x40) #define RING_SYNC_1(base) ((base)+0x44) -#define GEN6_RVSYNC (RING_SYNC_0(RENDER_RING_BASE)) -#define GEN6_RBSYNC (RING_SYNC_1(RENDER_RING_BASE)) -#define GEN6_VRSYNC (RING_SYNC_1(GEN6_BSD_RING_BASE)) -#define GEN6_VBSYNC (RING_SYNC_0(GEN6_BSD_RING_BASE)) -#define GEN6_BRSYNC (RING_SYNC_0(BLT_RING_BASE)) +#define RING_SYNC_2(base) ((base)+0x48) +#define GEN6_RVSYNC (RING_SYNC_0(RENDER_RING_BASE)) +#define GEN6_RBSYNC (RING_SYNC_1(RENDER_RING_BASE)) +#define GEN6_RVESYNC (RING_SYNC_2(RENDER_RING_BASE)) +#define GEN6_VBSYNC (RING_SYNC_0(GEN6_BSD_RING_BASE)) +#define GEN6_VRSYNC (RING_SYNC_1(GEN6_BSD_RING_BASE)) +#define GEN6_VVESYNC (RING_SYNC_2(GEN6_BSD_RING_BASE)) +#define GEN6_BRSYNC (RING_SYNC_0(BLT_RING_BASE)) +#define GEN6_BVSYNC (RING_SYNC_1(BLT_RING_BASE)) +#define GEN6_BVESYNC (RING_SYNC_2(BLT_RING_BASE)) +#define GEN6_VEBSYNC (RING_SYNC_0(VEBOX_RING_BASE)) +#define GEN6_VERSYNC (RING_SYNC_1(VEBOX_RING_BASE)) +#define GEN6_VEVSYNC (RING_SYNC_2(VEBOX_RING_BASE)) #define GEN6_NOSYNC 0 -#define GEN6_BVSYNC (RING_SYNC_1(BLT_RING_BASE)) #define RING_MAX_IDLE(base) ((base)+0x54) #define RING_HWS_PGA(base) ((base)+0x80) #define RING_HWS_PGA_GEN6(base) ((base)+0x2080) diff --git a/drivers/gpu/drm/i915/intel_ringbuffer.c b/drivers/gpu/drm/i915/intel_ringbuffer.c index ead979a94105..93ccd1e982e0 100644 --- a/drivers/gpu/drm/i915/intel_ringbuffer.c +++ b/drivers/gpu/drm/i915/intel_ringbuffer.c @@ -1688,9 +1688,11 @@ int intel_init_render_ring_buffer(struct drm_device *dev) ring->semaphore_register[RCS] = MI_SEMAPHORE_SYNC_INVALID;
