Pooled EU is a bxt only feature and kernel changes are already merged. This feature is not yet exposed to userspace as the support was not yet available. Beignet team expressed interest and added patches to use this. Since we now have a user and patches to use them, expose them from the kernel side as well. v2: fix compile error [1] https://lists.freedesktop.org/archives/beignet/2016-June/007698.html [2] https://lists.freedesktop.org/archives/beignet/2016-June/007699.html Cc: Winiarski, Michal <michal.winiarski@xxxxxxxxx> Cc: Zou, Nanhai <nanhai.zou@xxxxxxxxx> Cc: Yang, Rong R <rong.r.yang@xxxxxxxxx> Cc: Tim Gore <tim.gore@xxxxxxxxx> Cc: Jeff McGee <jeff.mcgee@xxxxxxxxx> Signed-off-by: Arun Siluvery <arun.siluvery@xxxxxxxxxxxxxxx> --- drivers/gpu/drm/i915/i915_drv.c | 6 ++++++ include/uapi/drm/i915_drm.h | 2 ++ 2 files changed, 8 insertions(+) diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c index c580e24..8a26740 100644 --- a/drivers/gpu/drm/i915/i915_drv.c +++ b/drivers/gpu/drm/i915/i915_drv.c @@ -365,6 +365,12 @@ static int i915_getparam(struct drm_device *dev, void *data, case I915_PARAM_HAS_EXEC_SOFTPIN: value = 1; break; + case I915_PARAM_HAS_POOLED_EU: + value = HAS_POOLED_EU(dev); + break; + case I915_PARAM_MIN_EU_IN_POOL: + value = INTEL_INFO(dev)->min_eu_in_pool; + break; default: DRM_DEBUG("Unknown parameter %d\n", param->param); return -EINVAL; diff --git a/include/uapi/drm/i915_drm.h b/include/uapi/drm/i915_drm.h index c17d63d..a642bbc 100644 --- a/include/uapi/drm/i915_drm.h +++ b/include/uapi/drm/i915_drm.h @@ -361,6 +361,8 @@ typedef struct drm_i915_irq_wait { #define I915_PARAM_HAS_GPU_RESET 35 #define I915_PARAM_HAS_RESOURCE_STREAMER 36 #define I915_PARAM_HAS_EXEC_SOFTPIN 37 +#define I915_PARAM_HAS_POOLED_EU 38 +#define I915_PARAM_MIN_EU_IN_POOL 39 typedef struct drm_i915_getparam { __s32 param; -- 1.9.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
