2021-10-28drm/amd/display: Defer GAMCOR and DSCL power down sequence to vupdateMichael Strauss
[WHY] Every other CM LUT power down sequence is deferred to next vupdate as memory powerdown updates immediately while selecting LUTs is double buffered. Previous update to defer LUT power down missed GAMCOR and DSCL, causing some visible flicker when entering/exiting fullscreen video playback. [HOW] Update dpp deferred update loop to check for valid DPPs in res_pool instead of referencing dcn_ip which turns out to not be populated during runtime. Move GAMCOR and DSCL powerdown to dpp deferred updates.

2021-10-28ice: Add support to print error on PHY FW load failureBrett Creeley
Some devices have support for loading the PHY FW and in some cases this can fail. When this fails, the FW will set the corresponding bit in the link info structure. Also, the FW will send a link event if the correct link event mask bit is set. Add support for printing an error message when the PHY FW load fails during any link configuration flow and the link event flow. Since ice_check_module_power() is already doing something very similar add a new function ice_check_link_cfg_err() so any failures reported in the link info's link_cfg_err member can be printed in this one function. Also, add the new ICE_FLAG_PHY_FW_LOAD_FAILED bit to the PF's flags so we don't constantly print this error message during link polling if the value never changed.

2021-10-28ice: send correct vc status in switchdevMichal Swiatkowski
Part of virtchannel messages are treated in different way in switchdev mode to block configuring VFs from iavf driver side. This blocking was done by doing nothing and returning success, event without sending response. Not sending response for opcodes that aren't supported in switchdev mode leads to block iavf driver message handling. This happens for example when vlan is configured at VF config time (VLAN module is already loaded). To get rid of it ice driver should answer for each VF message. In switchdev mode: - for adding/deleting VLAN driver should answer success without doing anything to allow creating vlan device on VFs - for enabling/disabling VLAN stripping and promiscuous mode driver should answer not supported, this feature in switchdev can be only set from host side Signed-off-by: Michal Swiatkowski <michal.swiatkowski@linux.intel.com> Tested-by: Sandeep Penigalapati <sandeep.penigalapati@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

This makes sure that both types of callbacks are handled correctly. The zynqmp_dma driver currently doesn't do this and only handles the `callback` type callback.

2021-10-28dmaengine: xilinx_dma: Correctly handle cyclic descriptor callbacksLars-Peter Clausen
DMA clients can provide one of two types of callbacks. For this reason dmaengine drivers should not directly invoke `callback`, but always use `dmaengine_desc_callback_invoke()`. This makes sure that both types of callbacks are handled correctly. The xilinx_dma driver currently doesn't do this for cyclic descriptors and only handles the `callback` type callback. If the client used the `callback_result` type callback it will not be called. Fix this by switching to `dmaengine_desc_callback_valid()` and `dmaengine_desc_callback_invoke()`.

2021-10-28dmaengine: qcom: bam_dma: Add "powered remotely" modeStephan Gerhold
In some configurations, the BAM DMA controller is set up by a remote processor and the local processor can simply start making use of it without setting up the BAM. This is already supported using the "qcom,controlled-remotely" property. However, for some reason another possible configuration is that the remote processor is responsible for powering up the BAM, but we are still responsible for initializing it (e.g. resetting it etc). This configuration is quite challenging to handle properly because the power control is handled through separate channels (e.g. device-specific SMSM interrupts / smem-states). Great care must be taken to ensure the BAM registers are not accessed while the BAM is powered off since this results in a bus stall. Attempt to support this configuration with minimal device-specific code in the bam_dma driver by tracking the number of requested channels. Consumers of DMA channels are responsible to only request DMA channels when the BAM was powered on by the remote processor, and to release them before the BAM is powered off. When the first channel is requested the BAM is initialized (reset) and it is also put into reset when the last channel was released.

2021-10-28vfio/ccw: Convert to use vfio_register_emulated_iommu_dev()Jason Gunthorpe
This is a more complicated conversion because vfio_ccw is sharing the vfio_device between both the mdev_device, its vfio_device and the css_driver. The mdev is a singleton, and the reason for this sharing is so the extra css_driver function callbacks to be delivered to the vfio_device implementation. This keeps things as they are, with the css_driver allocating the singleton, not the mdev_driver. Embed the vfio_device in the vfio_ccw_private and instantiate it as a vfio_device when the mdev probes. The drvdata of both the css_device and the mdev_device point at the private, and container_of is used to get it back from the vfio_device.
