From 41907ddc1b71aaa4ef5290f46f0ec49d581d6aac Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Fri, 8 Feb 2013 11:32:47 -0800 Subject: drm/i915: Fix gen2 mappable calculations When I refactored the code initially, I forgot that gen2 uses a different bar for the CPU mappable aperture. The agp-less code knows nothing of generations less than 5, so we have to expand the gtt_probe function to include the mappable base and end. It was originally broken by me: commit baa09f5fd8a6d033ec075355dda99a65b7f6a0f3 Author: Ben Widawsky Date: Thu Jan 24 13:49:57 2013 -0800 drm/i915: Add probe and remove to the gtt ops Reported-by: Chris Wilson Signed-off-by: Ben Widawsky Signed-off-by: Daniel Vetter --- drivers/char/agp/intel-gtt.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'drivers/char/agp/intel-gtt.c') diff --git a/drivers/char/agp/intel-gtt.c b/drivers/char/agp/intel-gtt.c index d8e7e6c9114..207e5c36e9e 100644 --- a/drivers/char/agp/intel-gtt.c +++ b/drivers/char/agp/intel-gtt.c @@ -1371,10 +1371,13 @@ int intel_gmch_probe(struct pci_dev *bridge_pdev, struct pci_dev *gpu_pdev, } EXPORT_SYMBOL(intel_gmch_probe); -void intel_gtt_get(size_t *gtt_total, size_t *stolen_size) +void intel_gtt_get(size_t *gtt_total, size_t *stolen_size, + phys_addr_t *mappable_base, unsigned long *mappable_end) { *gtt_total = intel_private.gtt_total_entries << PAGE_SHIFT; *stolen_size = intel_private.stolen_size; + *mappable_base = intel_private.gma_bus_addr; + *mappable_end = intel_private.gtt_mappable_entries << PAGE_SHIFT; } EXPORT_SYMBOL(intel_gtt_get); -- cgit v1.2.3-70-g09d2
