Hi, V2 series of the render state initialization patches. I decided not to pursue the copying of the context object as the ctx is quite big, atleast on bdw. As discussed in irc, the copying could be done with blitter, on context creation time. But even then we would need to wait for it to complete. Pushing 1kbytes of commands doesn't sound so bad when the alternative is to copy 18 pages. The state generators can be found here but they are not needed for testing. http://cgit.freedesktop.org/~miku/intel-gpu-tools/log/?h=null_state_gen Here is the branch for testing: http://cgit.freedesktop.org/~miku/drm-intel/log/?h=render_state Thank you to all who provided feedback. -Mika Mika Kuoppala (2): drm/i915: add render state initialization drm/i915: add null render states for gen6, gen7 and gen8 drivers/gpu/drm/i915/Makefile | 6 + drivers/gpu/drm/i915/i915_drv.h | 2 + drivers/gpu/drm/i915/i915_gem_context.c | 6 + drivers/gpu/drm/i915/i915_gem_render_state.c | 186 ++++++++++ drivers/gpu/drm/i915/intel_renderstate.h | 48 +++ drivers/gpu/drm/i915/intel_renderstate_gen6.c | 289 +++++++++++++++ drivers/gpu/drm/i915/intel_renderstate_gen7.c | 253 +++++++++++++ drivers/gpu/drm/i915/intel_renderstate_gen8.c | 479 +++++++++++++++++++++++++ 8 files changed, 1269 insertions(+) create mode 100644 drivers/gpu/drm/i915/i915_gem_render_state.c create mode 100644 drivers/gpu/drm/i915/intel_renderstate.h create mode 100644 drivers/gpu/drm/i915/intel_renderstate_gen6.c create mode 100644 drivers/gpu/drm/i915/intel_renderstate_gen7.c create mode 100644 drivers/gpu/drm/i915/intel_renderstate_gen8.c -- 1.7.9.5 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
