Hi all, This patch series enables the unmappable part of the gtt where available (g33/pineview and gen4 and later). I've already sent out the required drm core changes to dri-devel. Current wip branch for this is available at
git://anongit.freedesktop.org/~danvet/drm full-gtt It seems to work rather well and decently improves performance for workloads that now fit into the gtt and previously didn't. The last patch is the most experimental one (and the one I'm most interested in testing feedback): It expands the gtt to fully use the pagetable preallocated by the bios (it looks like the free room in there was intended for ppggt usage). This results in a 2GB aperture on my ilk, which not even virtual forbidden city can fill ;). This only works on gen5 hw (as Chris Wilson found out the hard way). Review, comments and test-reports highly welcome. Yours, Daniel Daniel Vetter (6): drm/i915: range-restricted eviction support drm/i915: range-restricted bind_to_gtt drm/i915: unbind unmappable objects on fault/pin drm/i915: use the complete gtt intel-gtt: save PGETBL_CTL later in the setup process intel-gtt: maximize ggtt size on platforms that support this drivers/char/agp/intel-agp.h | 14 +++- drivers/char/agp/intel-gtt.c | 110 +++++++++++++++++++++--------- drivers/gpu/drm/i915/i915_dma.c | 14 +++-- drivers/gpu/drm/i915/i915_drv.h | 10 ++- drivers/gpu/drm/i915/i915_gem.c | 89 +++++++++++++++++++------ drivers/gpu/drm/i915/i915_gem_evict.c | 24 +++++-- drivers/gpu/drm/i915/intel_display.c | 6 +- drivers/gpu/drm/i915/intel_overlay.c | 4 +- drivers/gpu/drm/i915/intel_ringbuffer.c | 4 +- 9 files changed, 197 insertions(+), 78 deletions(-) _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
