2025-01-06net: phylink: add support for PCS supported_interfaces bitmapRussell King (Oracle)
Add support for the PCS to specify which interfaces it supports, which can be used by MAC drivers to build the main supported_interfaces bitmap. Phylink also validates that the PCS returned by the MAC driver supports the interface that the MAC was asked for. An empty supported_interfaces bitmap from the PCS indicates that it does not provide this information, and we handle that appropriately.

kfd_process_wq_release() signals eviction fence by dma_fence_signal() which wanrs if dma_fence is NULL. kfd_process->ef is initialized by kfd_process_device_init_vm() through ioctl.

2025-01-06drm/amd/display: fix divide error in DM plane scale calcsMelissa Wen
dm_get_plane_scale doesn't take into account plane scaled size equal to zero, leading to a kernel oops due to division by zero. Fix by setting out-scale size as zero when the dst size is zero, similar to what is done by drm_calc_scale(). This issue started with the introduction of cursor ovelay mode that uses this function to assess cursor mode changes via dm_crtc_get_cursor_mode() before checking plane state.

DC driver is using two different values to define the maximum number of surfaces: MAX_SURFACES and MAX_SURFACE_NUM. Consolidate MAX_SURFACES as the unique definition for surface updates across DC. It fixes page fault faced by Cosmic users on AMD display versions that support two overlay planes, since the introduction of cursor overlay mode.

2025-01-06netkit: Allow for configuring needed_{head,tail}roomDaniel Borkmann
Allow the user to configure needed_{head,tail}room for both netkit devices. The idea is similar to 163e529200af ("veth: implement ndo_set_rx_headroom") with the difference that the two parameters can be specified upon device creation. By default the current behavior stays as is which is needed_{head,tail}room is 0. In case of Cilium, for example, the netkit devices are not enslaved into a bridge or openvswitch device (rather, BPF-based redirection is used out of tcx), and as such these parameters are not propagated into the Pod's netns via peer device. Given Cilium can run in vxlan/geneve tunneling mode (needed_headroom) and/or be used in combination with WireGuard (needed_{head,tail}room), allow the Cilium CNI plugin to specify these two upon netkit device creation.

2025-01-04net: libwx: fix firmware mailbox abnormal returnJiawen Wu
The existing SW-FW interaction flow on the driver is wrong. Follow this wrong flow, driver would never return error if there is a unknown command. Since firmware writes back 'firmware ready' and 'unknown command' in the mailbox message if there is an unknown command sent by driver. So reading 'firmware ready' does not timeout. Then driver would mistakenly believe that the interaction has completed successfully. It tends to happen with the use of custom firmware. Move the check for 'unknown command' out of the poll timeout for 'firmware ready'. And adjust the debug log so that mailbox messages are always printed when commands timeout.

2025-01-04net: stmmac: TSO: Simplify the code flow of DMA descriptor allocationsFurong Xu
The TCP Segmentation Offload (TSO) engine is an optional function in DWMAC cores, it is implemented for dwmac4 and dwxgmac2 only, ancient dwmac100 and dwmac1000 are not supported by hardware. Current driver code checks priv->dma_cap.tsoen which is read from MAC_HW_Feature1 register to determine if TSO is enabled in hardware configurations, if (!priv->dma_cap.tsoen) driver never sets NETIF_F_TSO for net_device. This patch never affects dwmac100/dwmac1000 and their stmmac_desc_ops: ndesc_ops/enh_desc_ops, since TSO is never supported by them two. The DMA AXI address width of DWMAC cores can be configured to 32-bit/40-bit/48-bit, then the format of DMA transmit descriptors get a little different between 32-bit and 40-bit/48-bit. Current driver code checks priv->dma_cap.addr64 to use certain format with certain configuration. This patch converts the format of DMA transmit descriptors on dwmac4 and dwxgmac2 that the DMA AXI address width is configured to 32-bit (as described by function comments of stmmac_tso_xmit() in current code) to a more generic format (see updated function comments after this patch) which is actually already used on 40-bit/48-bit platforms to provide better compatibility and make code flow cleaner in TSO TX routine. Another interesting finding, struct stmmac_desc_ops is a common abstract interface to maintain descriptors, we should avoid the direct assignment of descriptor members (e.g. desc->des0), stmmac_set_desc_addr() is the proper method yet. This patch tries to improve this by the way. Tested and verified on: DWMAC CORE 5.00a with 32-bit DMA AXI address width DWMAC CORE 5.10a with 32-bit DMA AXI address width DWXGMAC CORE 3.20a with 40-bit DMA AXI address width Signed-off-by: Furong Xu <0x1207@gmail.com> Link: https://patch.msgid.link/20241220080726.1733837-1-0x1207@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2025-01-04drm/mediatek: Initialize pointer in mtk_drm_of_ddp_path_build_one()AngeloGioacchino Del Regno
The struct device_node *next pointer is not initialized, and it is used in an error path in which it may have never been modified by function mtk_drm_of_get_ddp_ep_cid(). Since the error path is relying on that pointer being NULL for the OVL Adaptor and/or invalid component check and since said pointer is being used in prints for %pOF, in the case that it points to a bogus address, the print may cause a KP. To resolve that, initialize the *next pointer to NULL before usage.
