qed/qed_dev: guard against a possible division by zero Previously we would divide total_left_rate by zero if num_vports happened to be 1 because non_requested_count is calculated as num_vports - req_count. Guard against this by validating num_vports at the beginning and returning an error otherwise. Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.

qlogic: qed: fix clang -Wformat warnings When building with Clang we encounter these warnings: | drivers/net/ethernet/qlogic/qed/qed_dev.c:416:30: error: format | specifies type 'char' but the argument has type 'u32' (aka 'unsigned | int') [-Werror,-Wformat] i); - | drivers/net/ethernet/qlogic/qed/qed_dev.c:630:13: error: format | specifies type 'char' but the argument has type 'int' [-Werror,-Wformat] | p_llh_info->num_ppfid - 1); For the first warning, `i` is a u32 which is much wider than the format specifier `%hhd` describes. This results in a loss of bits after 2^7. The second warning involves implicit integer promotion as the resulting type of addition cannot be smaller than an int. example: `` uint8_t a = 4, b = 7; int size = sizeof(a + b - 1); printf("%d\n", size); // output: 4 ``` See more: (https://wiki.sei.cmu.edu/confluence/display/c/INT02-C.+Understand+integer+conversion+rules) "Integer types smaller than int are promoted when an operation is performed on them. If all values of the original type can be represented as an int, the value of the smaller type is converted to an int; otherwise, it is converted to an unsigned int."

qed: prevent a fw assert during device shutdown Device firmware can assert if the device shutdown path in driver encounters an async. events from mfw (processed in qed_mcp_handle_events()) after qed_mcp_unload_req() returns. A call to qed_mcp_unload_req() currently marks the device as inactive and thus stops any new events, but there is a windows where in-flight events might still be received by the driver. To prevent this race condition, atomically set QED_MCP_BYPASS_PROC_BIT in qed_mcp_unload_req() to make sure qed_mcp_handle_events() ignores all events. Wait for any event that might already be in-process to complete by monitoring QED_MCP_IN_PROCESSING_BIT.

ethernet: constify references to netdev->dev_addr in drivers This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

qed: Fix use after free in qed_chain_free The qed_chain data structure was modified in commit 1a4a69751f4d ("qed: Chain support for external PBL") to support receiving an external pbl (due to iWARP FW requirements). The pages pointed to by the pbl are allocated in qed_chain_alloc and their virtual address are stored in an virtual addresses array to enable accessing and freeing the data. The physical addresses however weren't stored and were accessed directly from the external-pbl during free. Destroy-qp flow, leads to freeing the external pbl before the chain is freed, when the chain is freed it tries accessing the already freed external pbl, leading to a use-after-free. Therefore we need to store the physical addresses in additional to the virtual addresses in a new data structure.

qed: Add abstraction for different hsi values per chip The number of BTB blocks was modified to be different between the two chip flavors supported (BB/K2) as a result, this lead to a re-write of selecting the default hsi value based on the chip. This patch creates a lookup table for hsi values per chip rather than ask again and again for every value.

qed: FW 8.42.2.0 Additional ll2 type LL2 queues were a limited resource due to FW constraints. This FW introduced a new resource which is a context based ll2 queue (memory on host). The additional ll2 queues are required for RDMA SRIOV. The code refers to the previous ll2 queues as ram-based or legacy, and the new queues as ctx-based. This change decreased the "legacy" ram-based queues therefore the first ll2 queue used for iWARP was converted to the ctx-based ll2 queue. This feature also exposed a bug in the DIRECT_REG_WR64 macro implementation which didn't have an effect in other use cases.

qed: Use dmae to write to widebus registers in fw_funcs There are several wide-bus registers written to by the fw_funcs that require using the dmae for atomicity. Therefore using the dmae channel functionality was added to the fw_funcs file, since the code is very similar to the previously used code, the structures used were moved to qed_hsi. Due to FW conventions, the names of the flags in the struct changed. Since this required slight modification in the places that set the flags the code was modified to use GET/SET FIELD macros.

qed: Fix -Wmaybe-uninitialized false positive A previous attempt to shut up the uninitialized variable use warning was apparently insufficient. When CONFIG_PROFILE_ANNOTATED_BRANCHES is set, gcc-8 still warns, because the unlikely() check in DP_NOTICE() causes it to no longer track the state of all variables correctly: drivers/net/ethernet/qlogic/qed/qed_dev.c: In function 'qed_llh_set_ppfid_affinity': drivers/net/ethernet/qlogic/qed/qed_dev.c:798:47: error: 'abs_ppfid' may be used uninitialized in this function [-Werror=maybe-uninitialized] addr = NIG_REG_PPF_TO_ENGINE_SEL + abs_ppfid * 0x4; ~~~~~~~~~~^~~~~ This is not a nice workaround, but always initializing the output from qed_llh_abs_ppfid() at least shuts up the false positive reliably.

qed: Add llh ppfid interface and 100g support for offload protocols This patch refactors the current llh implementation. It exposes a hw resource called ppfid (port-pfid) and implements an API for configuring the resource. Default configuration which was used until now limited the number of filters per PF and did not support engine affinity per protocol. The new API enables allocating more filter rules per PF and enables affinitizing protocol packets to a certain engine which enables full 100g protocol offload support.

qed: Fix QM getters to always return a valid pq The getter callers doesn't know the valid Physical Queues (PQ) values. This patch makes sure that a valid PQ will always be returned. The patch consists of 3 fixes: - When qed_init_qm_get_idx_from_flags() receives a disabled flag, it returned PQ 0, which can potentially be another function's pq. Verify that flag is enabled, otherwise return default start_pq. - When qed_init_qm_get_idx_from_flags() receives an unknown flag, it returned NULL and could lead to a segmentation fault. Return default start_pq instead. - A modulo operation was added to MCOS/VFS PQ getters to make sure the PQ returned is in range of the required flag.

qed: Fix rdma_info structure allocation Certain flows need to access the rdma-info structure, for example dcbx update flows. In some cases there can be a race between the allocation or deallocation of the structure which was done in roce start / roce stop and an asynchrounous dcbx event that tries to access the structure. For this reason, we move the allocation of the rdma_info structure to be similar to the iscsi/fcoe info structures which are allocated during device setup. We add a new field of "active" to the struct to define whether roce has already been started or not, and this is checked instead of whether the pointer to the info structure.

qed: Add Multi-TC RoCE support RoCE qps use a pair of physical queues (pq) received from the Queue Manager (QM) - an offload queue (OFLD) and a low latency queue (LLT). The QM block creates a pq for each TC, and allows RoCE qps to ask for a pq with a specific TC. As a result, qps with different VLAN priorities can be mapped to different TCs, and employ features such as PFC and ETS.

treewide: kzalloc() -> kcalloc() The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

qed*: Refactor mf_mode to consist of bits. `mf_mode' field indicates the multi-partitioning mode the device is configured to. This method doesn't scale very well, adding a new MF mode requires going over all the existing conditions, and deciding whether those are needed for the new mode or not. The patch defines a set of bit-fields for modes which are derived according to the mode info shared by the MFW and all the configuration would be made according to those. To add a new mode, there would be a single place where we'll need to go and choose which bits apply and which don't.

qed: VFs to try utilizing the doorbell bar VFs are currently not mapping their doorbell bar, instead relying on the small doorbell window they have in their limited regview bar. In order to increase the number of possible Tx connections [queues] employeed by VF past 16, we need to start using the doorbell bar if one such is exposed - VF would communicate this fact to PF which would return the size-bar internally configured into chip, according to which the VF would decide whether to actually utilize the doorbell bar.

qed: Reset IGU CAM to default on init The IGU CAM contains an assocaition between hardware SBs and interrupt lines, and it can be dynamically configured to allow more interrupts in one entity over another, specifically for Re-distibution of SBs between a PF and its child VFs. While we don't yet use this functionality, there are other clients that do and as such its possible the information passed from management firmware during initialization in regard to the possible number of SBs doesn't accurately reflect the current HW configuration. The following changes are going to apply to the driver init sequence: a. PF is going to re-configure all entries belonging to itself and its child VFs in IGU CAM based on the management firmware info regarding the number of SBs that are supposed to exist there. b. PF is going to stop using the SB resource [management firmware provided information] for anything but the initialization. Instead, it would use the live-time counters it maintains for the numbers.

qed: Don't use main-ptt in unrelated flows In order to access HW registers driver needs to acquire a PTT entry [mapping between bar memory and internal chip address]. Since acquiring PTT entries could fail [at least in theory] as their number is finite and other flows can hold them, we reserve special PTT entries for 'important' enough flows - ones we want to guarantee that would not be susceptible to such issues. One such special entry is the 'main' PTT which is meant to be used in flows such as chip initialization and de-initialization. However, there are other flows that are also using that same entry for their own purpose, and might run concurrently with the original flows [notice that for most cases using the main-ptt by mistake, such a race is still impossible, at least today]. This patch re-organizes the various functions that currently use the main_ptt in one of two ways: - If a function shouldn't use the main_ptt it starts acquiring and releasing it's own PTT entry and use it instead. Notice if those functions previously couldn't fail, they now can [as acquisition might fail]. - Change the prototypes so that the main_ptt would be received as a parameter [instead of explicitly accessing it]. This prevents the future risk of adding codes that introduces new use-cases for flows using the main_ptt, ones that might be in race with the actual 'main' flows.

This assumption might be incorrect, e.g., in case of preboot driver running and initializing the driver prior to our driver. To overcome this, we now ask management firmware to initiate a PF-flr early during the initialization sequence. That would return everything in the PF's scope back to default and prevent previous configurations from still being applied.

But the existing flow is too weak to handle some scenarios where PFs aren't properly cleaned prior to loading. The significant scenarios falling under this criteria: a. Preboot drivers in some environment can't properly unload. b. Unexpected driver replacement [kdump, PDA]. Modern management firmware supports a more intricate loading flow, where the driver has the ability to overcome previous limitations. This moves qed into using this newer scheme. Notice new scheme is backward compatible, so new drivers would still be able to load properly on top of older management firmwares and vice versa.

Existing HW stop flow utilizes 2 different functions: qed_hw_stop() and qed_hw_reset() which don't abide this requirement; Most of the closure is doing outside the scope of the unload request.

qed*: Handle-based L2-queues. The driver needs to maintain several FW/HW-indices for each one of its queues. Currently, that mapping is done by the QED where it uses an rx/tx array of so-called hw-cids, populating them whenever a new queue is opened and clearing them upon destruction of said queues. This maintenance is far from ideal - there's no real reason why QED needs to maintain such a data-structure. It becomes even worse when considering the fact that the PF's queues and its child VFs' queues are all mapped into the same data-structure. As a by-product, the set of parameters an interface needs to supply for queue APIs is non-trivial, and some of the variables in the API structures have different meaning depending on their exact place in the configuration flow. This patch re-organizes the way L2 queues are configured and maintained. In short: - Required parameters for queue init are now well-defined. - Qed would allocate a queue-cid based on parameters. Upon initialization success, it would return a handle to caller. - Queue-handle would be maintained by entity requesting queue-init, not necessarily qed. - All further queue-APIs [update, destroy] would use the opaque handle as reference for the queue instead of various indices. The possible owners of such handles: - PF queues [qede] - complete handles based on provided configuration. - VF queues [qede] - fw-context-less handles, containing only relative information; Only the PF-side would need the absolute indices for configuration, so they're omitted here. - VF queues [qed, PF-side] - complete handles based on VF initialization.

E.g., qede's Tx has one such chain and its Rx has two. Currently, the strucutre's fields which are required for datapath related functions [produce/consume] are intertwined with fields which are required only for configuration purposes [init/destroy/etc.].

qed*: Fix Kconfig dependencies with INFINIBAND_QEDR The qedr driver would require a tristate Kconfig option [to allow it to compile as a module], and toward that end we've added the INFINIBAND_QEDR option. But as we've made the compilation of the qed/qede infrastructure required for RoCE dependent on the option we'd be facing linking difficulties in case that QED=y or QEDE=y, and INFINIBAND_QEDR=m. To resolve this, we seperate between the INFINIBAND_QEDR option and the infrastructure support in qed/qede by introducing a new QED_RDMA option which would be selected by INFINIBAND_QEDR but would be a boolean instead of a tristate; Following that, the qed/qede is fixed based on this new option so that all config combinations would be supported.

qed: Fix error flow on slowpath start In case of problems when initializing the chip, the error flows aren't being properly done. Specifically, it's possible that the chip would be left in a configuration allowing it [internally] to access the host memory, causing fatal problems in the device that would require power cycle to overcome.

qed: Support B0 instead of A0 BB_A0 is a development model that is will not reach actual clients. In fact, future firmware would simply fail to initialize such chip. This changes the configuration into B0 instead of A0, and adds a safeguard against the slim chance someone would actually try this with an A0 adapter in which case probe would gracefully fail.

qed: Add module with basic common support The Qlogic Everest Driver is the backend module for the QL4xxx ethernet products by Qlogic. This module serves two main purposes: 1. It's responsible to contain all the common code that will be shared between the various drivers that would be used with said line of products. Flows such as chip initialization and de-initialization fall under this category. 2. It would abstract the protocol-specific HW & FW components, allowing the protocol drivers to have a clean APIs which is detached in its slowpath configuration from the actual HSI. This adds a very basic module without any protocol-specific bits. I.e., this adds a basic implementation that almost entirely falls under the first category.
