2022-03-21drm/vmwgfx: Disable command buffers on svga3 without gbobjectsZack Rusin
With very limited vram on svga3 it's difficult to handle all the surface migrations. Without gbobjects, i.e. the ability to store surfaces in guest mobs, there's no reason to support intermediate svga2 features, especially because we can fall back to fb traces and svga3 will never support those in-between features. On svga3 we wither want to use fb traces or screen targets (i.e. gbobjects), nothing in between. This fixes presentation on a lot of fusion/esxi tech previews where the exposed svga3 caps haven't been finalized yet.

2022-03-21drm/vmwgfx: Fix mob cursor allocation raceZack Rusin
Writes to SVGA_REG_CURSOR_MOBID did not wait for the buffers to be fully populated. This sometimes results in the device not being aware of the buffer when the cursor mob register was written. Properly wait for the buffer to be fully populated before setting it as a cursor mob.

2022-03-21drm/vmwgfx: Fix an invalid readZack Rusin
vmw_move assumed that buffers to be moved would always be vmw_buffer_object's but after introduction of new placement for mob pages that's no longer the case. The resulting invalid read didn't have any practical consequences because the memory isn't used unless the object actually is a vmw_buffer_object. Fix it by moving the cast to the spot where the results are used.

The rest are shared between multicast, link aggregation, and virtualization profiles. The GLAG area is reserved to not be used by anything else, since it is a subset of the MCAST area.

2022-03-21nfp: nfdk: implement xdp tx path for NFDKYinjun Zhang
Due to the different definition of txbuf in NFDK comparing to NFD3, there're no pre-allocated txbufs for xdp use in NFDK's implementation, we just use the existed rxbuf and recycle it when xdp tx is completed. For each packet to transmit in xdp path, we cannot use more than `NFDK_TX_DESC_PER_SIMPLE_PKT` txbufs, one is to stash virtual address, and another is for dma address, so currently the amount of transmitted bytes is not accumulated. Also we borrow the last bit of virtual addr to indicate a new transmitted packet due to address's alignment attribution.

2022-03-21nfp: add support for NFDK data pathJakub Kicinski
Add new data path. The TX is completely different, each packet has multiple descriptor entries (between 2 and 32). TX ring is divided into blocks 32 descriptor, and descritors of one packet can't cross block bounds. The RX side is the same for now. ABI version 5 or later is required. There is no support for VLAN insertion on TX. XDP_TX action and AF_XDP zero-copy is not implemented in NFDK path. Changes to Jakub's work: * Move statistics of hw_csum_tx after jumbo packet's segmentation. * Set L3_CSUM flag to enable recaculating of L3 header checksum in ipv4 case. * Mark the case of TSO a packet with metadata prepended as unsupported.

Supposedly there should be no systems where this isn't true, and it'll allow us to: - use the same code regardless of older vs. newer platform - wm latencies already treat 0 as disabled, so this fits well with other related code - make it a bit more clear when SAGV is used vs. not - avoid overflows from adding U32_MAX with a u16 wm0 latency value which could cause us to miscalculate the SAGV watermarks on tgl+ Cc: stable@vger.kernel.org Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220309164948.10671-2-ville.syrjala@linux.intel.com Reviewed-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> (cherry picked from commit d8f5855b31c0523ea3b171db8dfb998830e8735d) Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

The structures in igt_check_plane_state() total 1008 bytes, so any small amount of inlining will cause the stack frame to exceed the 32-bit limit of 1024, triggering the warning.

Add support for the IST3038C touchscreen IC from Imagis, based on downstream driver. The driver supports multi-touch (10 touch points) The IST3038C IC supports touch keys, but the support isn't added because the touch screen used for testing doesn't utilize touch keys. Looking at the downstream driver, it is possible to add support for other Imagis ICs of IST30**C series.

2022-03-20i2c: mux: demux-pinctrl: do not deactivate a master that is not activePeter Rosin
Attempting to rollback the activation of the current master when the current master has not been activated is bad. priv->cur_chan and priv->cur_adap are both still zeroed out and the rollback may result in attempts to revert an of changeset that has not been applied and do result in calls to both del and put the zeroed out i2c_adapter. Maybe it crashes, or whatever, but it's bad in any case.

The bus can be used just after i2c_add_adapter, so move i2c_add_adapter to the final step as meson_i2c_set_clk_div needs to be called before the bus is used.

When XDP is enabled, fragmentation scheme on non-linear legacy RQ is adjusted to comply to limitations of XDP multi buffer (fragments of the same size). DMA addresses of fragments are stored in struct page for the completion handler to be able to unmap them. XDP_TX is supported. XDP_REDIRECT is not yet supported, the XDP core blocks it for multi buffer packets at the moment. 2) Trivial cleanups ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
