From 0908180b9a1cf8c5410d0c1151894fae710744dc Mon Sep 17 00:00:00 2001 From: Daniele Ceraolo Spurio Date: Mon, 10 Apr 2017 07:34:29 -0700 Subject: [PATCH] drm/i915: Classify the engines in class + instance In such a way that vcs and vcs2 are just two different instances (0 and 1) of the same engine class (VIDEO_DECODE_CLASS). v2: Align the instance types (Tvrtko) v3: Don't use enums for bspec-defined stuff (Michal) Cc: Paulo Zanoni Cc: Rodrigo Vivi Cc: Chris Wilson Signed-off-by: Daniele Ceraolo Spurio Reviewed-by: Tvrtko Ursulin Reviewed-by: Michal Wajdeczko Signed-off-by: Oscar Mateo Link: http://patchwork.freedesktop.org/patch/msgid/1491834873-9345-2-git-send-email-oscar.mateo@intel.com Reviewed-by: Chris Wilson Signed-off-by: Chris Wilson --- drivers/gpu/drm/i915/i915_reg.h | 8 ++++++++ drivers/gpu/drm/i915/intel_engine_cs.c | 14 ++++++++++++++ drivers/gpu/drm/i915/intel_ringbuffer.h | 4 ++++ 3 files changed, 26 insertions(+) diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 11b12f412492..4c72adae368b 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -85,6 +85,14 @@ static inline bool i915_mmio_reg_valid(i915_reg_t reg) #define VECS_HW 3 #define VCS2_HW 4 +/* Engine class */ + +#define RENDER_CLASS 0 +#define VIDEO_DECODE_CLASS 1 +#define VIDEO_ENHANCEMENT_CLASS 2 +#define COPY_ENGINE_CLASS 3 +#define OTHER_CLASS 4 + /* PCI config space */ #define MCHBAR_I915 0x44 diff --git a/drivers/gpu/drm/i915/intel_engine_cs.c b/drivers/gpu/drm/i915/intel_engine_cs.c index 92f871cf3265..bb229274c30d 100644 --- a/drivers/gpu/drm/i915/intel_engine_cs.c +++ b/drivers/gpu/drm/i915/intel_engine_cs.c @@ -30,6 +30,8 @@ static const struct engine_info { const char *name; unsigned int exec_id; unsigned int hw_id; + u8 class; + u8 instance; u32 mmio_base; unsigned irq_shift; int (*init_legacy)(struct intel_engine_cs *engine); @@ -39,6 +41,8 @@ static const struct engine_info { .name = "rcs", .hw_id = RCS_HW, .exec_id = I915_EXEC_RENDER, + .class = RENDER_CLASS, + .instance = 0, .mmio_base = RENDER_RING_BASE, .irq_shift = GEN8_RCS_IRQ_SHIFT, .init_execlists = logical_render_ring_init, @@ -48,6 +52,8 @@ static const struct engine_info { .name = "bcs", .hw_id = BCS_HW, .exec_id = I915_EXEC_BLT, + .class = COPY_ENGINE_CLASS, + .instance = 0, .mmio_base = BLT_RING_BASE, .irq_shift = GEN8_BCS_IRQ_SHIFT, .init_execlists = logical_xcs_ring_init, @@ -57,6 +63,8 @@ static const struct engine_info { .name = "vcs", .hw_id = VCS_HW, .exec_id = I915_EXEC_BSD, + .class = VIDEO_DECODE_CLASS, + .instance = 0, .mmio_base = GEN6_BSD_RING_BASE, .irq_shift = GEN8_VCS1_IRQ_SHIFT, .init_execlists = logical_xcs_ring_init, @@ -66,6 +74,8 @@ static const struct engine_info { .name = "vcs2", .hw_id = VCS2_HW, .exec_id = I915_EXEC_BSD, + .class = VIDEO_DECODE_CLASS, + .instance = 1, .mmio_base = GEN8_BSD2_RING_BASE, .irq_shift = GEN8_VCS2_IRQ_SHIFT, .init_execlists = logical_xcs_ring_init, @@ -75,6 +85,8 @@ static const struct engine_info { .name = "vecs", .hw_id = VECS_HW, .exec_id = I915_EXEC_VEBOX, + .class = VIDEO_ENHANCEMENT_CLASS, + .instance = 0, .mmio_base = VEBOX_RING_BASE, .irq_shift = GEN8_VECS_IRQ_SHIFT, .init_execlists = logical_xcs_ring_init, @@ -101,6 +113,8 @@ intel_engine_setup(struct drm_i915_private *dev_priv, engine->hw_id = engine->guc_id = info->hw_id; engine->mmio_base = info->mmio_base; engine->irq_shift = info->irq_shift; + engine->class = info->class; + engine->instance = info->instance; /* Nothing to do here, execute in order of dependencies */ engine->schedule = NULL; diff --git a/drivers/gpu/drm/i915/intel_ringbuffer.h b/drivers/gpu/drm/i915/intel_ringbuffer.h index cbe61d3f31da..f54fe7d063a8 100644 --- a/drivers/gpu/drm/i915/intel_ringbuffer.h +++ b/drivers/gpu/drm/i915/intel_ringbuffer.h @@ -193,6 +193,10 @@ struct intel_engine_cs { enum intel_engine_id id; unsigned int exec_id; unsigned int hw_id; + + u8 class; + u8 instance; + unsigned int guc_id; u32 mmio_base; unsigned int irq_shift; -- 2.30.2
