And if we have a need for more contexts on those engines the usual rules apply: I need a fully enabled open-source userspace implementation using this new capability. -Daniel > --- > drivers/gpu/drm/i915/intel_lrc.c | 6 ------ > 1 file changed, 6 deletions(-) > > diff --git a/drivers/gpu/drm/i915/intel_lrc.c b/drivers/gpu/drm/i915/intel_lrc.c > index a656b48..0a944c2 100644 > --- a/drivers/gpu/drm/i915/intel_lrc.c > +++ b/drivers/gpu/drm/i915/intel_lrc.c > @@ -85,12 +85,6 @@ gen8_gem_validate_context(struct drm_device *dev, struct drm_file *file, > struct i915_hw_context *ctx = NULL; > struct i915_ctx_hang_stats *hs; > > - /* There is no reason why we cannot accept non-default, non-render contexts, > - * other than it changes the ABI (these kind of custom contexts have not been > - * allowed before) */ > - if (ring->id != RCS && ctx_id != DEFAULT_CONTEXT_ID) > - return ERR_PTR(-EINVAL); > - > ctx = i915_gem_context_get(file->driver_priv, ctx_id); > if (IS_ERR(ctx)) > return ctx; > -- > 1.9.0 > > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/intel-gfx -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch
