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.

2021-12-08drm/omap: introduce omap_hw_overlayBenoit Parrot
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.

2021-12-08drm/omap: Add ability to check if requested plane modes can be supportedBenoit Parrot
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().

2021-12-08drm/omap: add sanity plane state checkNeil Armstrong
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.

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.

2021-12-07net: fec: only clear interrupt of handling queue in fec_enet_rx_queue()Joakim Zhang
Background: We have a customer is running a Profinet stack on the 8MM which receives and responds PNIO packets every 4ms and PNIO-CM packets every 40ms. However, from time to time the received PNIO-CM package is "stock" and is only handled when receiving a new PNIO-CM or DCERPC-Ping packet (tcpdump shows the PNIO-CM and the DCERPC-Ping packet at the same time but the PNIO-CM HW timestamp is from the expected 40 ms and not the 2s delay of the DCERPC-Ping). After debugging, we noticed PNIO, PNIO-CM and DCERPC-Ping packets would be handled by different RX queues. The root cause should be driver ack all queues' interrupt when handle a specific queue in fec_enet_rx_queue(). The blamed patch is introduced to receive as much packets as possible once to avoid interrupt flooding. But it's unreasonable to clear other queues'interrupt when handling one queue, this patch tries to fix it.

2021-12-08vrf: don't run conntrack on vrf with !dflt qdiscNicolas Dichtel
After the below patch, the conntrack attached to skb is set to "notrack" in the context of vrf device, for locally generated packets. But this is true only when the default qdisc is set to the vrf device. When changing the qdisc, notrack is not set anymore. In fact, there is a shortcut in the vrf driver, when the default qdisc is set, see commit dcdd43c41e60 ("net: vrf: performance improvements for IPv4") for more details. This patch ensures that the behavior is always the same, whatever the qdisc is. To demonstrate the difference, a new test is added in conntrack_vrf.sh.

2021-12-07ice: fix adding different tunnelsMichal Swiatkowski
Adding filters with the same values inside for VXLAN and Geneve causes HW error, because it looks exactly the same. To choose between different type of tunnels new recipe is needed. Add storing tunnel types in creating recipes function and start checking it in finding function. Change getting open tunnels function to return port on correct tunnel type. This is needed to copy correct port to dummy packet. Block user from adding enc_dst_port via tc flower, because VXLAN and Geneve filters can be created only with destination port which was previously opened.

2021-12-07ice: fix choosing UDP header typeMichal Swiatkowski
In tunnels packet there can be two UDP headers: - outer which for hw should be mark as ICE_UDP_OF - inner which for hw should be mark as ICE_UDP_ILOS or as ICE_TCP_IL if inner header is of TCP type In none tunnels packet header can be: - UDP, which for hw should be mark as ICE_UDP_ILOS - TCP, which for hw should be mark as ICE_TCP_IL Change incorrect ICE_UDP_OF for none tunnel packets to ICE_UDP_ILOS. ICE_UDP_OF is incorrect for none tunnel packets and setting it leads to error from hw while adding this kind of recipe. In summary, for tunnel outer port type should always be set to ICE_UDP_OF, for none tunnel outer and tunnel inner it should always be set to ICE_UDP_ILOS.

2021-12-07ice: ignore dropped packets during initJesse Brandeburg
If the hardware is constantly receiving unicast or broadcast packets during driver load, the device previously counted many GLV_RDPC (VSI dropped packets) events during init. This causes confusing dropped packet statistics during driver load. The dropped packets counter incrementing does stop once the driver finishes loading. Avoid this problem by baselining our statistics at the end of driver open instead of the end of probe.

The patch that implemented DSCP QoS implementation removed a bandwidth check that was used to check for a specific condition caused by some corner cases. This check should not of been removed. The same patch also added a check for when the DCBx state could be changed in relation to DSCP, but the check was erroneously added nested in a check for CEE mode, which made the check useless. Fix these problems by re-adding the bandwidth check and relocating the DSCP mode check earlier in the function that changes DCBx state in the driver.
