2018-10-10net: dsa: bcm_sf2: Fix unbind orderingFlorian Fainelli
The order in which we release resources is unfortunately leading to bus errors while dismantling the port. This is because we set priv->wol_ports_mask to 0 to tell bcm_sf2_sw_suspend() that it is now permissible to clock gate the switch. Later on, when dsa_slave_destroy() comes in from dsa_unregister_switch() and calls dsa_switch_ops::port_disable, we perform the same dismantling again, and this time we hit registers that are clock gated. Make sure that dsa_unregister_switch() is the first thing that happens, which takes care of releasing all user visible resources, then proceed with clock gating hardware. We still need to set priv->wol_ports_mask to 0 to make sure that an enabled port properly gets disabled in case it was previously used as part of Wake-on-LAN.

Jakub Kicinski says: ==================== nfp: flower: speed up stats update loop This set from Pieter improves performance of processing FW stats update notifications. The FW seems to send those at relatively high rate (roughly ten per second per flow), therefore if we want to approach the million flows mark we have to be very careful about our data structures. We tried rhashtable for stat updates, but according to our experiments rhashtable lookup on a u32 takes roughly 60ns on an Xeon E5-2670 v3. Which translate to a hard limit of 16M lookups per second on this CPU, and, according to perf record jhash and memcmp account for 60% of CPU usage on the core handling the updates. Given that our statistic IDs are already array indices, and considering each statistic is only 24B in size, we decided to forego the use of hashtables and use a directly indexed array. The CPU savings are considerable. With the recent improvements in TC core and with our own bottlenecks out of the way Pieter removes the artificial limit of 128 flows, and allows the driver to install as many flows as FW supports. ==================== Signed-off-by: David S.

2018-10-10Merge branch 'octeontx2-af-Add-RVU-Admin-Function-driver'David S. Miller
Sunil Goutham says: ==================== octeontx2-af: Add RVU Admin Function driver Resource virtualization unit (RVU) on Marvell's OcteonTX2 SOC maps HW resources from the network, crypto and other functional blocks into PCI-compatible physical and virtual functions. Each functional block again has multiple local functions (LFs) for provisioning to PCI devices. RVU supports multiple PCIe SRIOV physical functions (PFs) and virtual functions (VFs). PF0 is called the administrative / admin function (AF) and has privileges to provision RVU functional block's LFs to each of the PF/VF. RVU managed networking functional blocks - Network pool allocator (NPA) - Network interface controller (NIX) - Network parser CAM (NPC) - Schedule/Synchronize/Order unit (SSO) RVU managed non-networking functional blocks - Crypto accelerator (CPT) - Scheduled timers unit (TIM) - Schedule/Synchronize/Order unit (SSO) Used for both networking and non networking usecases - Compression (upcoming in future variants of the silicons) Resource provisioning examples - A PF/VF with NIX-LF & NPA-LF resources works as a pure network device - A PF/VF with CPT-LF resource works as a pure cyrpto offload device. This admin function driver neither receives any data nor processes it i.e no I/O, a configuration only driver. PF/VFs communicates with AF via a shared memory region (mailbox). Upon receiving requests from PF/VF, AF does resource provisioning and other HW configuration. AF is always attached to host, but PF/VFs may be used by host kernel itself, or attached to VMs or to userspace applications like DPDK etc. So AF has to handle provisioning/configuration requests sent by any device from any domain. This patch series adds logic for the following - RVU AF driver with functional blocks provisioning support. - Mailbox infrastructure for communication between AF and PFs. - CGX (MAC controller) driver which communicates with firmware for managing physical ethernet interfaces. AF collects info from this driver and forwards the same to the PF/VFs uaing these interfaces. This is the first set of patches out of 80+ patches.

2018-10-10octeontx2-af: Scan blocks for LFs provisioned to PF/VFSunil Goutham
Scan all RVU blocks to find any 'LF to RVU PF/VF' mapping done by low level firmware. If found any, mark them as used in respective block's LF bitmap and also save mapped PF/VF's PF_FUNC info. This is done to avoid reattaching a block LF to a different RVU PF/VF. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
