2021-10-04qed: Update common_hsi for FW ver 8.59.1.0Prabhakar Kushwaha
The common_hsi.h has been updated for FW version 8.59.1.0 with below changes. - FW and Tools version. - New structures related to search table, packet duplication. - Structure for doorbell address for legacy mode without DEM. - Enhanced union rdma_eqe_data for RoCE Suspend Event Data. - New defines. This patch also fixes the existing checkpatch warnings and few important checks.

2021-10-04qed: Split huge qed_hsi.h header fileOmkar Kulkarni
The qed_hsi.h is a huge header file containing HSI (Hardware Software Interface) definitions of storm memory access, debug related, general and management firmware specific. In order to have a better code-organization HSI definition, this patch split the code across multiple files, i.e. - storm memory access HSI : qed_iro_hsi.h - debug related HSI : qed_dbg_hsi.h - Management firmware HSI : qed_mfg_hsi.h - General HSI : qed_hsi.h In addition, this patch also fixes existing checkpatch warnings and few important checks.

2021-10-04qed: Remove e4_ and _e4 from FW HSIShai Malin
The existing qed/qede/qedr/qedi/qedf code uses chip-specific naming in structures, functions, variables and defines in FW HSI (Hardware Software Interface). The new FW version introduced a generic naming convention in HSI in-which the same code will be used across different versions for simpler maintainability. It also eases in providing support for new features. With this patch every "_e4" or "e4_" prefix or suffix is not needed anymore and it will be removed.

2021-08-09devlink: Set device as early as possibleLeon Romanovsky
All kernel devlink implementations call to devlink_alloc() during initialization routine for specific device which is used later as a parent device for devlink_register(). Such late device assignment causes to the situation which requires us to call to device_register() before setting other parameters, but that call opens devlink to the world and makes accessible for the netlink users. Any attempt to move devlink_register() to be the last call generates the following error due to access to the devlink->dev pointer. [ 8.758862] devlink_nl_param_fill+0x2e8/0xe50 [ 8.760305] devlink_param_notify+0x6d/0x180 [ 8.760435] __devlink_params_register+0x2f1/0x670 [ 8.760558] devlink_params_register+0x1e/0x20 The simple change of API to set devlink device in the devlink_alloc() instead of devlink_register() fixes all this above and ensures that prior to call to devlink_register() everything already set.

The source (&dcbx_info->operational.params) and dest (&p_hwfn->p_dcbx_info->set.config.params) are both struct qed_dcbx_params (560 bytes), not struct qed_dcbx_admin_params (564 bytes), which is used as the memcpy() size. However it seems that struct qed_dcbx_operational_params (dcbx_info->operational)'s layout matches struct qed_dcbx_admin_params (p_hwfn->p_dcbx_info->set.config)'s 4 byte difference (3 padding, 1 byte for "valid"). On the assumption that the size is wrong (rather than the source structure type), adjust the memcpy() size argument to be 4 bytes smaller and add a BUILD_BUG_ON() to validate any changes to the structure sizes.

2020-10-16Merge branch 'dynamic_sg' into rdma.git for-nextJason Gunthorpe
From Maor Gottlieb says: ==================== This series extends __sg_alloc_table_from_pages to allow chaining of new pages to an already initialized SG table. This allows for drivers to utilize the optimization of merging contiguous pages without a need to pre allocate all the pages and hold them in a very large temporary buffer prior to the call to SG table initialization. The last patch changes the Infiniband core to use the new API. It removes duplicate functionality from the code and benefits from the optimization of allocating dynamic SG table from pages. In huge pages system of 2MB page size, without this change, the SG table would contain x512 SG entries. ==================== * branch 'dynamic_sg': RDMA/umem: Move to allocate SG table from pages lib/scatterlist: Add support in dynamic allocation of SG table from pages tools/testing/scatterlist: Show errors in human readable form tools/testing/scatterlist: Rejuvenate bit-rotten test
2020-09-28qed/qed_ll2: Replace one-element array with flexible-array memberGustavo A. R. Silva
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct qed_ll2_tx_packet, instead of a one-element array and use the struct_size() helper to calculate the size for the allocations. Commit f5823fe6897c ("qed: Add ll2 option to limit the number of bds per packet") was used as a reference point for these changes. Also, it's important to notice that flexible-array members should occur last in any structure, and structures containing such arrays and that are members of other structures, must also occur last in the containing structure. That's why _cur_completing_packet_ is now moved to the bottom in struct qed_ll2_tx_queue. _descq_mem_ and _cur_send_packet_ are also moved for unification.

Two minor conflicts: 1) net/ipv4/route.c, adding a new local variable while moving another local variable and removing it's initial assignment. 2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes. One pretty prints the port mode differently, whilst another changes the driver to try and obtain the port mode from the port node rather than the switch node. Signed-off-by: David S.

zbva is always false, so fbo is never read. A 'zero-based-virtual-address' is simply IOVA == 0, and the driver already supports this.
