There are a few details specific to the GETFB2 IOCTL. It's not immediately clear how user-space should check for the number of planes. Suggest using the handles field or the pitches field. The modifier array is filled with zeroes, ie. DRM_FORMAT_MOD_LINEAR. So explicitly tell user-space to not look at it unless the flag is set. Changes in v2 (Daniel): - Mention that handles should be used to compute the number of planes, and only refer to pitches as a fallback. - Reword bit about undefined modifier. Signed-off-by:

Using MOBFMT_RANGE in the early days of guest backed objects was a major performance win but that has changed a lot since. There's no more a performance reason to use MOBFMT_RANGE. The device can/will still profit from the pages being contiguous but marking them as MOBFMT_RANGE no longer matters. Benchmarks (e.g. heaven, valley) show that creating page tables for mob memory is actually faster than using mobfmt ranges. Signed-off-by:

The fb handle code assumes it deals with GEM objects. Because vmwgfx buffer objects were not actually GEM objects we were not able to implement that interface. Now that vmwgfx supports GEM buffer objects we can trivially implement create_handle for buffer object backed framebuffers. Among others this gets IGT's kms_getfb test passing. Signed-off-by:

This is initial change adding support for DRIVER_GEM to vmwgfx. vmwgfx was written before GEM and has always used TTM. Over the years the TTM buffers started inherting from GEM objects but vmwgfx never implemented GEM making it quite awkward. We were directly setting variables in GEM objects to not make DRM crash. This change brings vmwgfx inline with other DRM drivers and allows us to use a lot of DRM helpers which have depended on drivers with GEM support. Due to historical reasons vmwgfx splits the idea of a buffer and surface which makes it a littly tricky since either one can be used in most of our ioctl's which take user space handles. For now our BO's are GEM objects and our surfaces are opaque objects which are backed by GEM objects. In the future I'd like to combine those into a single BO but we don't want to break any of our existing ioctl's so it will take time to do it in a non-destructive way. Signed-off-by:

Mob/GMR id resource manager was lacking the debug print callback which meant that during memory errors we weren't getting the details which are needed to fix those errors.

vmwgfx shared very elaborate memory accounting with ttm. It was moved from ttm to vmwgfx in change f07069da ("drm/ttm: move memory accounting into vmwgfx v4") but because of complexity it was hard to maintain. Some parts of the code weren't freeing memory correctly and some were missing accounting all together. While those would be fairly easy to fix the fundamental reason for memory accounting in the driver was the ability to invoke shrinker which is part of TTM code as well (with support for unified memory hopefully coming soon). That meant that vmwgfx had a lot of code that was either unused or duplicating code from TTM. Removing this code also prevents excessive calls to global swapout which were common during memory pressure because both vmwgfx and TTM would invoke the shrinker when memory usage reached half of RAM.

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. Signed-off-by:

(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.

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. Signed-off-by:

Split out the hardware overlay specifics from omap_plane. To start, the hw overlays are statically assigned to planes. The goal is to eventually assign hw overlays dynamically to planes during plane->atomic_check() based on requested caps (scaling, YUV, etc). And then perform hw overlay re-assignment if required.

We currently assume that an overlay has the same maximum width and maximum height as the overlay manager. This assumption is incorrect. On some variants the overlay manager maximum width is twice the maximum width that the overlay can handle. We need to add the appropriate data per variant as well as export a helper function to retrieve the data so check can be made dynamically in omap_plane_atomic_check(). Signed-off-by:

Call drm_atomic_helper_check_plane_state() from the plane atomic_check() callback in order to add plane state sanity checking. It will permit filtering out totally bad scaling factors, even if the real check are done later in the atomic commit. Calling drm_atomic_helper_check_plane_state() also sets plane_state->visible which will be useful when dynamically assigning hw overlays to planes. Signed-off-by:
