From 022d3093a9102a8b8b7a3796a8aba5a9c4e40ec7 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Wed, 28 Feb 2018 12:11:52 +0200 Subject: [PATCH] drm/i915/icl: Prepare for more rings Gen11 will add more VCS and VECS rings so prepare the infrastructure to support that. Bspec: 7021 v2: Rebase. v3: Rebase. v4: Rebase. v5: Rebase. v6: - Update for POR changes. (Daniele Ceraolo Spurio) - Add provisional guc engine ids - to be checked and confirmed. v7: - Rebased. - Added the new ring masks. - Added the new HW ids. v8: - Introduce I915_MAX_VCS/VECS to avoid magic numbers (Michal) v9: increase MAX_ENGINE_INSTANCE to 3 Cc: Michal Wajdeczko Signed-off-by: Tvrtko Ursulin Signed-off-by: Rodrigo Vivi Signed-off-by: Oscar Mateo Signed-off-by: Daniele Ceraolo Spurio Reviewed-by: Oscar Mateo Signed-off-by: Mika Kuoppala Link: https://patchwork.freedesktop.org/patch/msgid/20180228101153.7224-1-mika.kuoppala@linux.intel.com --- drivers/gpu/drm/i915/i915_drv.h | 3 +++ drivers/gpu/drm/i915/i915_gem.h | 2 +- drivers/gpu/drm/i915/i915_reg.h | 5 ++++- drivers/gpu/drm/i915/intel_device_info.c | 3 +++ drivers/gpu/drm/i915/intel_device_info.h | 4 +++- drivers/gpu/drm/i915/intel_ringbuffer.h | 9 ++++++++- 6 files changed, 22 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 7bbec55..10c9e5e 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -2746,6 +2746,9 @@ intel_info(const struct drm_i915_private *dev_priv) #define BLT_RING ENGINE_MASK(BCS) #define VEBOX_RING ENGINE_MASK(VECS) #define BSD2_RING ENGINE_MASK(VCS2) +#define BSD3_RING ENGINE_MASK(VCS3) +#define BSD4_RING ENGINE_MASK(VCS4) +#define VEBOX2_RING ENGINE_MASK(VECS2) #define ALL_ENGINES (~0) #define HAS_ENGINE(dev_priv, id) \ diff --git a/drivers/gpu/drm/i915/i915_gem.h b/drivers/gpu/drm/i915/i915_gem.h index d9f0709..f54c4ff 100644 --- a/drivers/gpu/drm/i915/i915_gem.h +++ b/drivers/gpu/drm/i915/i915_gem.h @@ -57,6 +57,6 @@ #define GEM_TRACE(...) do { } while (0) #endif -#define I915_NUM_ENGINES 5 +#define I915_NUM_ENGINES 8 #endif /* __I915_GEM_H__ */ diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index eea5b2c..95a2e51 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -178,6 +178,9 @@ static inline bool i915_mmio_reg_valid(i915_reg_t reg) #define BCS_HW 2 #define VECS_HW 3 #define VCS2_HW 4 +#define VCS3_HW 6 +#define VCS4_HW 7 +#define VECS2_HW 12 /* Engine class */ @@ -188,7 +191,7 @@ static inline bool i915_mmio_reg_valid(i915_reg_t reg) #define OTHER_CLASS 4 #define MAX_ENGINE_CLASS 4 -#define MAX_ENGINE_INSTANCE 1 +#define MAX_ENGINE_INSTANCE 3 /* PCI config space */ diff --git a/drivers/gpu/drm/i915/intel_device_info.c b/drivers/gpu/drm/i915/intel_device_info.c index 1c780cc..cadc5f8 100644 --- a/drivers/gpu/drm/i915/intel_device_info.c +++ b/drivers/gpu/drm/i915/intel_device_info.c @@ -542,6 +542,9 @@ void intel_device_info_runtime_init(struct intel_device_info *info) info->num_scalers[PIPE_C] = 1; } + BUILD_BUG_ON(I915_NUM_ENGINES > + sizeof(intel_ring_mask_t) * BITS_PER_BYTE); + /* * Skylake and Broxton currently don't expose the topmost plane as its * use is exclusive with the legacy cursor and we only want to expose diff --git a/drivers/gpu/drm/i915/intel_device_info.h b/drivers/gpu/drm/i915/intel_device_info.h index 8904ad8..ab5bfd3 100644 --- a/drivers/gpu/drm/i915/intel_device_info.h +++ b/drivers/gpu/drm/i915/intel_device_info.h @@ -125,6 +125,8 @@ struct sseu_dev_info { u8 has_eu_pg:1; }; +typedef u8 intel_ring_mask_t; + struct intel_device_info { u16 device_id; u16 gen_mask; @@ -132,7 +134,7 @@ struct intel_device_info { u8 gen; u8 gt; /* GT number, 0 if undefined */ u8 num_rings; - u8 ring_mask; /* Rings supported by the HW */ + intel_ring_mask_t ring_mask; /* Rings supported by the HW */ enum intel_platform platform; u32 platform_mask; diff --git a/drivers/gpu/drm/i915/intel_ringbuffer.h b/drivers/gpu/drm/i915/intel_ringbuffer.h index bbacf4d..90e4380 100644 --- a/drivers/gpu/drm/i915/intel_ringbuffer.h +++ b/drivers/gpu/drm/i915/intel_ringbuffer.h @@ -160,6 +160,9 @@ struct i915_ctx_workarounds { struct i915_request; +#define I915_MAX_VCS 4 +#define I915_MAX_VECS 2 + /* * Engine IDs definitions. * Keep instances of the same type engine together. @@ -169,8 +172,12 @@ enum intel_engine_id { BCS, VCS, VCS2, + VCS3, + VCS4, #define _VCS(n) (VCS + (n)) - VECS + VECS, + VECS2 +#define _VECS(n) (VECS + (n)) }; struct i915_priolist { -- 2.7.4
