This is the initial import of the helper for displayport multistream. It consists of a topology manager, init/destroy/set mst state It supports DP 1.2 MST sideband msg protocol handler - via hpd irqs connector detect and edid retrieval interface. It supports i2c device over DP 1.2 sideband msg protocol (EDID reads only) bandwidth manager API via vcpi allocation and payload updating, along with a helper to check the ACT status. Objects: MST topology manager - one per toplevel MST capable GPU port - not sure if this should be higher level again MST branch unit - one instance per plugged branching unit - one at top of hierarchy - others hanging from ports MST port - one port per port reported by branching units, can have MST units hanging from them as well. Changes since initial posting: a) add a mutex responsbile for the queues, it locks the sideband and msg slots, and msgs to transmit state b) add worker to handle connection state change events, for MST device chaining and hotplug c) add a payload spinlock d) add path sideband msg support e) fixup enum path resources transmit f) reduce max dpcd msg to 16, as per DP1.2 spec. g) separate tx queue kicking from irq processing and move irq acking back to drivers. Changes since v0.2: a) reorganise code, b) drop ACT forcing code c) add connector naming interface using path property d) add topology dumper helper e) proper reference counting and lookup for ports and mstbs. f) move tx kicking into a workq g) add aux locking - this should be redone h) split teardown into two parts i) start working on documentation on interface. Changes since v0.3: a) vc payload locking and tracking fixes b) add hotplug callback into driver - replaces crazy return 1 scheme c) txmsg + mst branch device refcount fixes d) don't bail on mst shutdown if device is gone e) change irq handler to take all 4 bytes of SINK_COUNT + ESI vectors f) make DP payload updates timeout longer - observed on docking station redock g) add more info to debugfs dumper Changes since v0.4: a) suspend/resume support b) more debugging in debugfs Changes since v0.5: a) use byte * to avoid unnecessary stack usage b) fix num_sdp_streams interpretation. c) init payload state for unplug events d) remove lenovo dock sink count hack e) drop aux lock - post rebase f) call hotplug on port destroy TODO: misc features Reviewed-by:

Thierry Reding authored
Describe how devices are registered using the drm_*_init() functions. Adding this to docbook requires a largish set of changes to the comments in drm_{pci,usb,platform}.c since they are doxygen-style rather than proper kernel-doc and therefore mess with the docbook generation. While at it, mark usage of drm_put_dev() as discouraged in favour of calling drm_dev_unregister() and drm_dev_unref() directly. Acked-by:

For atomic, it will be quite necessary to not need to care so much about locking order. And 'state' gives us a convenient place to stash a ww_ctx for any sort of update that needs to grab multiple crtc locks. Because we will want to eventually make locking even more fine grained (giving locks to planes, connectors, etc), split out drm_modeset_lock and drm_modeset_acquire_ctx to track acquired locks. Atomic will use this to keep track of which locks have been acquired in a transaction. v1: original v2: remove a few things not needed until atomic, for now v3: update for v3 of connection_mutex patch.. v4: squash in docbook v5: doc tweaks/fixes Signed-off-by:

Unfortunately this requires a drm-wide change, and I didn't see a sane way around that. Luckily it's fairly simple, we just need to inline the respective get_irq implementation from either drm_pci.c or drm_platform.c. With that we can now also remove drm_dev_to_irq from drm_irq.c. Reviewed-by:

This is leftover stuff from my previous doc round which I kinda wanted to do but didn't yet due to rebase hell. The modeset helpers and the probing helpers a independent and e.g. i915 uses the probing stuff but has its own modeset infrastructure. It hence makes to split this up. While at it add a DOC: comment for the probing libraray. It would be rather neat to pull some of the DocBook documenting these two helpers into in-line DOC: comments. But unfortunately kerneldoc doesn't support markdown or something similar to make nice-looking documentation, so the current state is better. Signed-off-by:

- Tune down yelling RETURNS. - OCD align all the parameters the same. - Add missing kerneldoc, which also means that we need to include the kerneldoc from the drm_modes.h header now. - Add missing Returns: sections. - General polish and clarification - especially the kerneldoc for the mode creation helpers seems to have been some good specimen of copypasta gone wrong. All actual code changes have all been extracted into prep patches since there was simply too much to polish. v2: More polish for the command line modeline functions. Reviewed-by:

While at it do a tiny bit of interface cleanup and convert boolean return values to bool.

kerneldoc polish will follow in the next patch. Hopefully documenting the lru scan support a bit better spurs someone to give this a shot in the ttm eviction code. At least in i915 it helped quite a lot with memory thrashing on platforms where eviction was (we've fixed that too meanwhile) fairly expensive. Reviewed-by:

For giant hilarity the DocBook reference overview is only generated when in a level 2 section, not in a level 3 section. So we need to move this up a bit as a side-by-side section to the main PRIME documentation. Whatever. To have a complete set of references add the missing kerneldoc for all functions exported to modules with the exception of the file private init/destroy functions - drivers have no business calling those, so let's just drop the EXPORT_SYMBOL instead. Also reflow the function parameters to align correctly and break at 80 chars - my OCD couldn't stand them while writing the kerneldoc ;-) Reviewed-by:

PRIME fds aren't actually GEM fds but are (like the modeset API) independent of the underlying buffer manager, as long as that one uses uint32_t as handles. So move that entire section out of the GEM section and reword it a bit to clarify which parts of PRIME are generic, and which are the mandatory pieces for GEM drivers to correctly implement the GEM lifetime rules. The rewording mostly consists of not mixing up GEM, PRIME and DRM. I've considered adding some blurbs to the GEM object lifetime section about interactions with dma-bufs, but then dropped that. As long as drivers use the right helpers they should have this all implemented correctly and hence can be regarded as an implementation detail of the PRIME/GEM helpers. So no need to confuse driver writers with those tricky interactions. Reviewed-by:
