Currently for PF and ECPF vports, representors are created before their eswitch hardware ports are initialized in below flow. mlx5_eswitch_enable() esw_offloads_init() esw_offloads_load_all_reps() [..] esw_enable_vport() However for VFs, vports are initialized before creating their respective netdev represnetors in event handling context. Similarly while disabling eswitch, first hardware vports are disabled, followed by destroying their representors. Here while underlying vports gets destroyed but its respective user facing netdevice can still exist on which user can continue to perform more offload operations. Instead, its more accurate to do enable_eswitch switchdev mode: 1. perform FDB tables initialization 2. initialize hw vport 3. create and publish representor for this vport disable_eswitch switchdev mode: 1. destroy user facing representor for the vport 2. disable hw vport 3. perform FDB tables cleanup Signed-off-by:

mc_promisc pointer points to an instance of struct esw_mc_addr allocated as part of the esw structure. Hence it cannot be NULL. Removed such redundant check and assign where it is actually used. While at it, add comment around legacy mode fields and move mc_promisc close to other legacy mode structures to improve code redability. Signed-off-by:

vports needs to be enabled in switchdev and legacy mode. In switchdev mode, vports should be enabled after initializing the FDB tables and before creating their represntors so that representor works on an initialized vport object. Prepare a helper function which can be called when enabling either of the eswitch modes. Similarly, have disable vports helper function. Signed-off-by:

First enable TSAR Qos hardware block in device before enabling its user vports. This refactor is needed so that vports can be enabled before their representor netdevice can be created. While at it, esw_create_tsar() returns error code which was used only to print error. However esw_create_tsar() already prints warning if it hits an error. Hence, remove the redundant warning.

Towards introducing the ability to allocate bulks of flow counters, refactor the flow counter bulk query process, removing functions and structs whose names indicated being used for flow counter bulk allocation FW commands, despite them actually only being used to support bulk querying, and migrate their functionality to correctly named functions in their natural location, fs_counters.c. Additionally, optimize the bulk query process by: * Extracting the memory used for the query to mlx5_fc_stats so that it is only allocated once, and not for each bulk query. * Querying all the counters in one function call.

Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Risc-V CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema. Acked-by:

Pull CONFIG_PREEMPT_RT stub config from Thomas Gleixner: "The real-time preemption patch set exists for almost 15 years now and while the vast majority of infrastructure and enhancements have found their way into the mainline kernel, the final integration of RT is still missing. Over the course of the last few years, we have worked on reducing the intrusivenness of the RT patches by refactoring kernel infrastructure to be more real-time friendly. Almost all of these changes were benefitial to the mainline kernel on their own, so there was no objection to integrate them. Though except for the still ongoing printk refactoring, the remaining changes which are required to make RT a first class mainline citizen are not longer arguable as immediately beneficial for the mainline kernel. Most of them are either reordering code flows or adding RT specific functionality. But this now has hit a wall and turned into a classic hen and egg problem: Maintainers are rightfully wary vs. these changes as they make only sense if the final integration of RT into the mainline kernel takes place. Adding CONFIG_PREEMPT_RT aims to solve this as a clear sign that RT will be fully integrated into the mainline kernel. The final integration of the missing bits and pieces will be of course done with the same careful approach as we have used in the past. While I'm aware that you are not entirely enthusiastic about that, I think that RT should receive the same treatment as any other widely used out of tree functionality, which we have accepted into mainline over the years. RT has become the de-facto standard real-time enhancement and is shipped by enterprise, embedded and community distros. It's in use throughout a wide range of industries: telecommunications, industrial automation, professional audio, medical devices, data acquisition, automotive - just to name a few major use cases. RT development is backed by a Linuxfoundation project which is supported by major stakeholders of this technology. The funding will continue over the actual inclusion into mainline to make sure that the functionality is neither introducing regressions, regressing itself, nor becomes subject to bitrot. There is also a lifely user community around RT as well, so contrary to the grim situation 5 years ago, it's a healthy project. As RT is still a good vehicle to exercise rarely used code paths and to detect hard to trigger issues, you could at least view it as a QA tool if nothing else" * 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/rt, Kconfig: Introduce CONFIG_PREEMPT_RT

Pull SCSI fixes from James Bottomley: "This is the final round of mostly small fixes in our initial submit. It's mostly minor fixes and driver updates. The only change of note is adding a virt_boundary_mask to the SCSI host and host template to parametrise this for NVMe devices instead of having them do a call in slave_alloc. It's a fairly straightforward conversion except in the two NVMe handling drivers that didn't set it who now have a virtual infinity parameter added" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (24 commits) scsi: megaraid_sas: set an unlimited max_segment_size scsi: mpt3sas: set an unlimited max_segment_size for SAS 3.0 HBAs scsi: IB/srp: set virt_boundary_mask in the scsi host scsi: IB/iser: set virt_boundary_mask in the scsi host scsi: storvsc: set virt_boundary_mask in the scsi host template scsi: ufshcd: set max_segment_size in the scsi host template scsi: core: take the DMA max mapping size into account scsi: core: add a host / host template field for the virt boundary scsi: core: Fix race on creating sense cache scsi: sd_zbc: Fix compilation warning scsi: libfc: fix null pointer dereference on a null lport scsi: zfcp: fix GCC compiler warning emitted with -Wmaybe-uninitialized scsi: zfcp: fix request object use-after-free in send path causing wrong traces scsi: zfcp: fix request object use-after-free in send path causing seqno errors scsi: megaraid_sas: Update driver version to 07.710.50.00 scsi: megaraid_sas: Add module parameter for FW Async event logging scsi: megaraid_sas: Enable msix_load_balance for Invader and later controllers scsi: megaraid_sas: Fix calculation of target ID scsi: lpfc: reduce stack size with CONFIG_GCC_PLUGIN_STRUCTLEAK_VERBOSE scsi: devinfo: BLIST_TRY_VPD_PAGES for SanDisk Cruzer Blade ...
