2021-12-09drm/i915: Add has_64k_pages flagStuart Summers
Add a new platform flag, has_64k_pages, to mark the requirement of 64K GTT page sizes or larger for device local memory access. Also implies that we require or at least support the compact PT layout for the ppGTT when using 64K GTT pages. v2: More explanation for the flag [Thomas] Signed-off-by: Stuart Summers <stuart.summers@intel.com> Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211208141613.7251-2-ramalingam.c@intel.com

The upcoming privacy-screen support adds another check for deferring probe till some other drivers have bound first. Factor out the current vga_switcheroo_client_probe_defer() check into an intel_modeset_probe_defer() helper, so that further probe-deferral checks can be added there.

2021-12-09Revert "drm/fb-helper: improve DRM fbdev emulation device names"Javier Martinez Canillas
This reverts commit b3484d2b03e4c940a9598aa841a52d69729c582a. That change attempted to improve the DRM drivers fbdev emulation device names to avoid having confusing names like "simpledrmdrmfb" in /proc/fb. But unfortunately, there are user-space programs such as pm-utils that match against the fbdev names and so broke after the mentioned commit. Since the names in /proc/fb are used by tools that consider it an uAPI, let's restore the old names even when this lead to silly names like the one mentioned above.

2021-12-09drm/i915/trace: split out display trace to a separate fileJani Nikula
Add display/intel_display_trace.[ch] for defining display tracepoints. The main goal is to reduce cross-includes between gem and display. It would be possible split up tracing even further, but that would lead to more boilerplate. We end up having to include intel_crtc.h in a few places because it was pulled in implicitly via intel_de.h -> i915_trace.h -> intel_crtc.h, and that's no longer the case.

2021-12-08drm/syncobj: Deal with signalled fences in drm_syncobj_find_fence.Bas Nieuwenhuizen
dma_fence_chain_find_seqno only ever returns the top fence in the chain or an unsignalled fence. Hence if we request a seqno that is already signalled it returns a NULL fence. Some callers are not prepared to handle this, like the syncobj transfer functions for example. This behavior is "new" with timeline syncobj and it looks like not all callers were updated. To fix this behavior make sure that a successful drm_sync_find_fence always returns a non-NULL fence. v2: Move the fix to drm_syncobj_find_fence from the transfer functions.

2021-12-08drm/omap: Add a 'right overlay' to plane stateBenoit Parrot
If the drm_plane has a source width that's greater than the max width supported by a single hw overlay, then we assign a 'r_overlay' to it in omap_plane_atomic_check(). Both overlays should have the capabilities required to handle the source framebuffer. The only parameters that vary between the left and right hwoverlays are the src_w, crtc_w, src_x and crtc_x as we just even chop the fb into left and right halves. We also take care of not creating odd width size when dealing with YUV formats. Since both halves need to be 'appear' side by side the zpos is recalculated when dealing with dual overlay cases so that the other planes zpos is consistent. Depending on user space usage it is possible that on occasion the number of requested planes exceeds the numbers of overlays required to display them. In that case a failure would be returned for the plane that cannot be handled at that time. It is up to user space to make sure the H/W resource are not over-subscribed.

2021-12-08drm/omap: dynamically assign hw overlays to planesBenoit Parrot
(re)assign the hw overlays to planes based on required caps, and to handle situations where we could not modify an in-use plane. This means all planes advertise the superset of formats and properties. Userspace must (as always) use atomic TEST_ONLY step for atomic updates, as not all planes may be available for use on every frame. The mapping of hwoverlays to plane is stored in omap_global_state, so that state updates are atomically committed in the same way that plane/etc state updates are managed. This is needed because the omap_plane_state keeps a pointer to the hwoverlay, and we don't want global state to become out of sync with the plane state if an atomic update fails, we hit deadlock/ backoff scenario, etc. The use of global_state_lock keeps multiple parallel updates which both re-assign hwoverlays properly serialized.

2021-12-08drm/omap: Add global state as a private atomic objectBenoit Parrot
Global shared resources (like hw overlays) for omapdrm are implemented as a part of atomic state using the drm_private_obj infrastructure available in the atomic core. omap_global_state is introduced as a drm atomic private object. The two funcs omap_get_global_state() and omap_get_existing_global_state() are the two variants that will be used to access omap_global_state. drm_mode_config_init() needs to be called earlier because it creates/initializes the private_obj link list maintained by the atomic framework. The private_obj link list has to exist prior to calling drm_atomic_private_obj_init(). Similarly the cleanup handler are reordered appropriately.

Split out the hardware overlay specifics from omap_plane. To start, the hw overlays are statically assigned to planes.

2021-12-08drm: omapdrm: Export correct scatterlist for TILER backed BOsIvaylo Dimitrov
Memory of BOs backed by TILER is not contiguous, but omap_gem_map_dma_buf() exports it like it is. This leads to (possibly) invalid memory accesses if another device imports such a BO. Fix that by providing sg that correctly describes TILER memory layout. Align TILER allocations to page, so importer to be able to correctly set its MMU if have one. Set export size accounting for the alignment. Also, make sure to destroy sg on unpin, as it is no longer valid. Tested on Motorola Droid4 by using GPU (sgx540) to render.
