From 78b68556a964e74fb803b08c5b2d9c6ba3ec3787 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 17 May 2012 13:27:22 +0200 Subject: drm: Constify gem_vm_ops pointer The GEM vm operations structure is passed to the VM core that stores it in a const field. There vm operations structures can thus be const in DRM as well.

This adds handle->fd and fd->handle support to i915, this is to allow for offloading of rendering in one direction and outputs in the other. v2 from Daniel Vetter: - fixup conflicts with the prepare/finish gtt prep work. - implement ppgtt binding support. Note that we have squat i-g-t testcoverage for any of the lifetime and access rules dma_buf/prime support brings along. And there are quite a few intricate situations here. Also note that the integration with the existing code is a bit hackish, especially around get_gtt_pages and put_gtt_pages. It imo would be easier with the prep code from Chris Wilson's unbound series, but that is for 3.6. Also note that I didn't bother to put the new prepare/finish gtt hooks to good use by moving the dma_buf_map/unmap_attachment calls in there (like we've originally planned for). Last but not least this patch is only compile-tested, but I've changed very little compared to Dave Airlie's version. So there's a decent chance v2 on drm-next works as well as v1 on 3.4-rc. v3: Right when I've hit sent I've noticed that I've screwed up one obj->sg_list (for dmar support) and obj->sg_table (for prime support) disdinction. We should be able to merge these 2 paths, but that's material for another patch. v4: fix the error reporting bugs pointed out by ickle. v5: fix another error, and stop non-gtt mmaps on shared objects stop pread/pwrite on imported objects, add fake kmap Signed-off-by: Dave Airlie Signed-Off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_drv.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'drivers/gpu/drm/i915/i915_drv.c') diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c index 7b967d5bf51d..238a52165833 100644 --- a/drivers/gpu/drm/i915/i915_drv.c +++ b/drivers/gpu/drm/i915/i915_drv.c @@ -1039,7 +1039,7 @@ static struct drm_driver driver = { */ .driver_features = DRIVER_USE_AGP | DRIVER_REQUIRE_AGP | /* DRIVER_USE_MTRR |*/ - DRIVER_HAVE_IRQ | DRIVER_IRQ_SHARED | DRIVER_GEM, + DRIVER_HAVE_IRQ | DRIVER_IRQ_SHARED | DRIVER_GEM | DRIVER_PRIME, .load = i915_driver_load, .unload = i915_driver_unload, .open = i915_driver_open, @@ -1062,6 +1062,12 @@ static struct drm_driver driver = { .gem_init_object = i915_gem_init_object, .gem_free_object = i915_gem_free_object, .gem_vm_ops = &i915_gem_vm_ops, + + .prime_handle_to_fd = drm_gem_prime_handle_to_fd, + .prime_fd_to_handle = drm_gem_prime_fd_to_handle, + .gem_prime_export = i915_gem_prime_export, + .gem_prime_import = i915_gem_prime_import, + .dumb_create = i915_gem_dumb_create, .dumb_map_offset = i915_gem_mmap_gtt, .dumb_destroy = i915_gem_dumb_destroy, -- cgit v1.2.2
