ttm_global_reference was renamed to drm_global_reference. This updates the documentation to reflect that. While we are there, document the drm_global_reference API and update the initialization interface documentation. Signed-off-by:

Several DRM drivers print the same initialization message right after drm_dev_register, so move that to common code. The exception is i915, which uses its own register handle, so let it keep its own message. Notice that this was tested only with Exynos, but looks simple enough for the other drivers. Signed-off-by:

Currently at the end of drm_core_init() we print [ 0.735185] [drm] Initialized which does not provide any user information and is only a breadcrumb for developers, so reduce it from info to debug. Signed-off-by:

Function rockchip_crtc_from_pipe() does the exactly same thing as what crtc helper drm_crtc_from_index() provides. Use the helper to save some code. Signed-off-by:

It adds a crtc helper drm_crtc_from_index() to find the registered CRTC with a given index, just like drm_plane_from_index(). Signed-off-by:

Including all drivers. I thought about keeping small compat functions to avoid having to change all drivers. But I really like the drm_printer idea, so figured spreading it more widely is a good thing. v2: Review from Chris: - Natural argument order and better name for drm_mm_print. - show_mm() macro in the selftest.

mm->color_adjust() compares the hole with its neighbouring nodes. They only abutt before we restrict the hole, so we have to apply color_adjust before we apply the range restriction. Signed-off-by:

Insulate users from changes to the internal hole tracking within struct drm_mm_node by using an accessor for hole_follows. Signed-off-by:
-
Chris Wilson authored
Using mm->color_adjust makes the eviction scanner much tricker since we don't know the actual neighbours of the target hole until after it is created (after scanning is complete). To work out whether we need to evict the neighbours because they impact upon the hole, we have to then check the hole afterwards - requiring an extra step in the user of the eviction scanner when they apply color_adjust. v2: Massage kerneldoc.

Since we mandate a strict reverse-order of drm_mm_scan_remove_block() after drm_mm_scan_add_block() we can further simplify the list manipulations when generating the temporary scan-hole. v2: Highlight the games being played with the lists to track the scan holes without allocation. Signed-off-by:

Compute the minimal required hole during scan and only evict those nodes that overlap. This enables us to reduce the number of nodes we need to evict to the bare minimum. Signed-off-by:

The range restriction should be applied after the color adjustment, or else we may inadvertently apply the color adjustment to the restricted hole (and not against its neighbours). Signed-off-by:

Doing the check is trivial (low cost in comparison to overall eviction) and helps simplify the code. Signed-off-by:

Acknowledging that we were building up the hole was more useful to me when reading the code, than knowing the relationship between this node and the previous node. Signed-off-by:

The scan state occupies a large proportion of the struct drm_mm and is rarely used and only contains temporary state. That makes it suitable to moving to its struct and onto the stack of the callers. Signed-off-by:

A simple assert to ensure that we don't overflow start + size when initialising the drm_mm, or its scanner. In future, we may want to switch to tracking the value of ranges (rather than size) so that we can cover the full u64, for example like resource tracking. Signed-off-by:

Since commit ea7b1dd4 ("drm: mm: track free areas implicitly"), to test whether there are any nodes allocated within the range manager, we merely have to ask whether the node_list is empty. Signed-off-by:

The nodes must be removed in the *reverse* order. This is correct in the overview, but backwards in the function description. Whilst here add Intel's copyright statement and tweak some formatting. Signed-off-by:

In places (e.g. i915.ko), the alignment is exported to userspace as u64 and there now exists hardware for which we can indeed utilize a u64 alignment. As such, we need to keep 64bit integers throughout when handling alignment. Testcase: igt/drm_mm/align64 Testcase: igt/gem_exec_alignment Signed-off-by:
