In both cases, we don't have this information until after we've tried to kick out the firmware fb. This patch should have no functional change since we kzalloc the GTT struct anyway. It only clarifies the situation for people who end up having to look at that code. This weirdness was introduced in: commit 93d187993b783c68383a884091a600d9ad499ea6 Author: Ben Widawsky Date: Thu Jan 17 12:45:17 2013 -0800 drm/i915: Remove use of gtt_mappable_entries Signed-off-by: Ben Widawsky Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/i915_dma.c b/drivers/gpu/drm/i915/i915_dma.c index f5addac7c154..3cda7521e8d7 100644 --- a/drivers/gpu/drm/i915/i915_dma.c +++ b/drivers/gpu/drm/i915/i915_dma.c @@ -1431,7 +1431,7 @@ static void i915_kick_out_firmware_fb(struct drm_i915_private *dev_priv) return; ap->ranges[0].base = dev_priv->gtt.mappable_base; - ap->ranges[0].size = dev_priv->gtt.mappable_end - dev_priv->gtt.start; + ap->ranges[0].size = dev_priv->gtt.mappable_end; primary = pdev->resource[PCI_ROM_RESOURCE].flags & IORESOURCE_ROM_SHADOW;
