treewide: use get_random_u32() when possible

2022-10-11T23:42:58Z

The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

drm/i915: Move display and media IP version to runtime info

2022-09-12T21:52:34Z

Future platforms can read the IP version from a register and the IP version numbers need not be hard coded in device info. Move the ip version for media and display to runtime info. On platforms where hard coding of IP version is required, update the IP version in __runtime under device_info. v2: - Avoid name collision for ip versions(Jani) v4.1: - Fix build error in mock_gem_device.c v4.2: - Use ip instead of version for ip_vesion member.(MattR) Suggested-by: Jani Nikula Cc: Matt Roper Signed-off-by: Radhakrishna Sripada Reviewed-by: Matt Roper Link: https://patchwork.freedesktop.org/patch/msgid/20220902221054.173524-1-radhakrishna.sripada@intel.com

drm/i915: Prepare more multi-GT initialization

2022-09-12T12:23:12Z

We're going to introduce an additional intel_gt for MTL's media unit soon. Let's provide a bit more multi-GT initialization framework in preparation for that. The initialization will pull the list of GTs for a platform from the device info structure. Although necessary for the immediate MTL media enabling, this same framework will also be used farther down the road when we enable remote tiles on xehpsdv and pvc. v2: - Re-add missing test for !HAS_EXTRA_GT_LIST in intel_gt_probe_all(). v3: - Move intel_gt_definition struct to intel_gt_types.h. (Jani) - Drop gtdef->setup(). For now we'll just use a switch() based on GT type since we don't have too many different handlers for the foreseeable future.

drm/i915: Rename ggtt_view as gtt_view

2022-09-08T09:24:17Z

So far, different views (normal, partial, rotated and remapped) into the same object are only supported for GGTT mappings. But with the upcoming VM_BIND feature, PPGTT will also use the partial view mapping. Hence rename ggtt_view to more generic gtt_view.

drm/i915/selftests: allow misaligned_pin test work with unmappable memory

2022-08-30T12:45:21Z

In case of Small BAR configurations stolen local memory can be unmappable. Since the test does not touch the memory, passing I915_BO_ALLOC_GPU_ONLY flag to i915_gem_object_create_region, will prevent -ENOSPC error from _i915_gem_object_stolen_init.

Merge drm/drm-next into drm-intel-next

2022-08-29T12:14:59Z

Sync drm-intel-next with v6.0-rc as well as recent drm-intel-gt-next. Since drm-next does not have commit f0c70d41e4e8 ("drm/i915/guc: remove runtime info printing from time stamp logging") yet, only drm-intel-gt-next, will need to do that as part of the merge here to build.

drm/i915: move platform_engine_mask to runtime info

If it's modified runtime, it's runtime info. mock_gem_device() is the only one that modifies it. If that could be fixed, we wouldn't have to do this.
