2021-05-21xen-pciback: reconfigure also from backend watch handlerJan Beulich1-5/+17
When multiple PCI devices get assigned to a guest right at boot, libxl incrementally populates the backend tree. The writes for the first of the devices trigger the backend watch. In turn xen_pcibk_setup_backend() will set the XenBus state to Initialised, at which point no further reconfigures would happen unless a device got hotplugged. Arrange for reconfigure to also get triggered from the backend watch handler.

2021-05-21xen-pciback: redo VF placement in the virtual topologyJan Beulich1-6/+8
The commit referenced below was incomplete: It merely affected what would get written to the vdev-<N> xenstore node. The guest would still find the function at the original function number as long as __xen_pcibk_get_pci_dev() wouldn't be in sync. The same goes for AER wrt __xen_pcibk_get_pcifront_dev(). Undo overriding the function to zero and instead make sure that VFs at function zero remain alone in their slot. This has the added benefit of improving overall capacity, considering that there's only a total of 32 slots available right now (PCI segment and bus can both only ever be zero at present).

Current driver actually does not support simple ondemand governor as it's unable to provide device load information. So removing the unnecessary callback to avoid confusing.

2021-05-20net: encx24j600: fix kernel-doc syntax in file headersAditya Srivastava2-2/+2
The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. The header for drivers/net/ethernet/microchip/encx24j600 files follows this syntax, but the content inside does not comply with kernel-doc. This line was probably not meant for kernel-doc parsing, but is parsed due to the presence of kernel-doc like comment syntax(i.e, '/**'), which causes unexpected warning from kernel-doc. For e.g., running scripts/kernel-doc -none drivers/net/ethernet/microchip/encx24j600_hw.h emits: warning: expecting prototype for h(). Prototype was for _ENCX24J600_HW_H() instead Provide a simple fix by replacing such occurrences with general comment format, i.e. '/*', to prevent kernel-doc from parsing it.

Tony Nguyen says: ==================== 1GbE Intel Wired LAN Driver Updates 2021-05-20 This series contains updates to igc driver only. Andre Guedes says: This series adds AF_XDP zero-copy feature to igc driver. The initial patches do some code refactoring, preparing the code base to land the AF_XDP zero-copy feature, avoiding code duplications. The last patches of the series are the ones implementing the feature. The last patch which indeed implements AF_XDP zero-copy support was originally way too lengthy so, for the sake of code review, I broke it up into two patches: one adding support for the RX functionality and the other one adding TX support. --- v2: Patch 8/9 - "igc: Enable RX via AF_XDP zero-copy" * In XDP_PASS flow, copy metadata too into the skb. * When HW timestamp is added by the NIC, after copying it into a local variable, update xdp_buff->data_meta so that metadata length when XDP program is called 0. * In igc_xdp_enable_pool(), call xsk_pool_dma_unmap() on failure. Known issues: When an XDP application is running in Tx-Only mode with Zero-Copy enabled, it is not expected to add the frames to the fill-queue. I have noticed the following two issues in this scenario: - If XDP_USE_NEED_WAKEUP flag is not set by application, igc_poll() will go into infinite loop because the buffer allocation resulting in igc_clean_rx_irq_zc() indicating that all work is not done and NAPI should keep polling. This does not occur if XDP_USE_NEED_WAKEUP flag is set. - Since there are no buffers allocated by userspace for the fill queue, there is no memory allocated for the NIC to copy the data to. If the packet received is destined to the hardware queue where XDP application is running, no packets are received even on other queues. Both these issues can be mitigated by adding a few frames to the fill queue. The second issue can also be mitigated by making sure no packets are being received on the hardware queue where Rx is running. ==================== Signed-off-by: David S.
