drm/panfrost: Add the panfrost_gem_mapping concept

2020-01-21T16:32:55Z

With the introduction of per-FD address space, the same BO can be mapped in different address space if the BO is globally visible (GEM_FLINK) and opened in different context or if the dmabuf is self-imported. The current implementation does not take case into account, and attaches the mapping directly to the panfrost_gem_object. Let's create a panfrost_gem_mapping struct and allow multiple mappings per BO. The mappings are refcounted which helps solve another problem where mappings were torn down (GEM handle closed by userspace) while GPU jobs accessing those BOs were still in-flight. Jobs now keep a reference on the mappings they use. v2 (robh): - Minor review comment clean-ups from Steven - Use list_is_singular helper - Just WARN if we add a mapping when madvise state is not WILLNEED. With that, drop the use of object_name_lock. v3 (robh): - Revert returning list iterator in panfrost_gem_mapping_get() Fixes: a5efb4c9a562 ("drm/panfrost: Restructure the GEM object creation") Fixes: 7282f7645d06 ("drm/panfrost: Implement per FD address spaces") Cc: Signed-off-by: Boris Brezillon Signed-off-by: Rob Herring Acked-by: Boris Brezillon Reviewed-by: Steven Price Link: https://patchwork.freedesktop.org/patch/msgid/20200116021554.15090-1-robh@kernel.org

drm/i915: Align engine->uabi_class/instance with i915_drm.h

2020-01-21T07:25:20Z

In our ABI we have defined I915_ENGINE_CLASS_INVALID_NONE and I915_ENGINE_CLASS_INVALID_VIRTUAL as negative values which creates implicit coupling with type widths used in, also ABI, struct i915_engine_class_instance. One place where we export engine->uabi_class I915_ENGINE_CLASS_INVALID_VIRTUAL is from our our tracepoints. Because the type of the former is u8 in contrast to u16 defined in the ABI, 254 will be returned instead of 65534 which userspace would legitimately expect. Another place is I915_CONTEXT_PARAM_ENGINES. Therefore we need to align the type used to store engine ABI class and instance. v2: * Update the commit message mentioning get_engines and cc stable.

drm/i915/userptr: fix size calculation

2020-01-21T07:03:00Z

If we create a rather large userptr object(e.g 1ULL << 32) we might shift past the type-width of num_pages: (int)num_pages << PAGE_SHIFT, resulting in a totally bogus sg_table, which fortunately will eventually manifest as: gen8_ppgtt_insert_huge:463 GEM_BUG_ON(iter->sg->length < page_size) kernel BUG at drivers/gpu/drm/i915/gt/gen8_ppgtt.c:463! v2: more unsigned long prefer I915_GTT_PAGE_SIZE Fixes: 5cc9ed4b9a7a ("drm/i915: Introduce mapping of user pages into video memory (userptr) ioctl") Signed-off-by: Matthew Auld Cc: Chris Wilson Reviewed-by: Chris Wilson Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20200117132413.1170563-2-matthew.auld@intel.com (cherry picked from commit 8e78871bc1e5efec22c950d3fd24ddb63d4ff28a) Signed-off-by: Joonas Lahtinen
