2021-08-30bnxt_en: update all firmware calls to use the new APIsEdwin Peer
The conversion follows this general pattern for most of the calls: 1. The input message is changed from a stack variable initialized using bnxt_hwrm_cmd_hdr_init() to a pointer allocated and intialized using hwrm_req_init(). 2. If we don't need to read the firmware response, the hwrm_send_message() call is replaced with hwrm_req_send(). 3. If we need to read the firmware response, the mutex lock is replaced by hwrm_req_hold() to hold the response. When the response is read, the mutex unlock is replaced by hwrm_req_drop(). If additional DMA buffers are needed for firmware response data, the hwrm_req_dma_slice() is used instead of calling dma_alloc_coherent(). Some minor refactoring is also done while doing these conversions. v2: Fix unintialized variable warnings in __bnxt_hwrm_get_tx_rings() and bnxt_approve_mac() Signed-off-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2021-08-30bnxt_en: use link_lock instead of hwrm_cmd_lock to protect link_infoEdwin Peer
We currently use the hwrm_cmd_lock to serialize the update of the firmware's link status response data and the copying of link status data to the VF. This won't work when we update the firmware message APIs, so we use the link_lock mutex instead. All link_info data should be updated under the link_lock mutex. Also add link_lock to functions that touch link_info in __bnxt_open_nic() and bnxt_probe_phy(). The locking is probably not strictly necessary during probe, but it's more consistent.

2021-08-30bnxt_en: add support for HWRM request slicesEdwin Peer
Slices are a mechanism for suballocating DMA mapped regions from the request buffer. Such regions can be used for indirect command data instead of creating new mappings with dma_alloc_coherent(). The advantage of using a slice is that the lifetime of the slice is bound to the request and will be automatically unmapped when the request is consumed. A single external region is also supported. This allows for regions that will not fit inside the spare request buffer space such that the same API can be used consistently even for larger mappings.

2021-08-30bnxt_en: discard out of sequence HWRM responsesEdwin Peer
During firmware crash recovery, it is possible for firmware to respond to stale HWRM commands that have already timed out. Because response buffers may be reused, any out of sequence responses need to be ignored and only the matching seq_id should be accepted. Also, READ_ONCE should be used for the reads from the DMA buffer to ensure that the necessary loads are scheduled.

2021-08-30bnxt_en: introduce new firmware message API based on DMA poolsEdwin Peer
This change constitutes a major step towards supporting multiple firmware commands in flight by maintaining a separate response buffer for the duration of each request. These firmware commands are also known as Hardware Resource Manager (HWRM) commands. Using separate response buffers requires an API change in order for callers to be able to free the buffer when done. It is impossible to keep the existing APIs unchanged. The existing usage for a simple HWRM message request such as the following: struct input req = {0}; bnxt_hwrm_cmd_hdr_init(bp, &req, REQ_TYPE, -1, -1); rc = hwrm_send_message(bp, &req, sizeof(req), HWRM_CMD_TIMEOUT); if (rc) /* error */ changes to: struct input *req; rc = hwrm_req_init(bp, req, REQ_TYPE); if (rc) /* error */ rc = hwrm_req_send(bp, req); /* consumes req */ if (rc) /* error */ The key changes are: 1. The req is no longer allocated on the stack. 2. The caller must call hwrm_req_init() to allocate a req buffer and check for a valid buffer. 3. The req buffer is automatically released when hwrm_req_send() returns. 4. If the caller wants to check the firmware response, the caller must call hwrm_req_hold() to take ownership of the response buffer and release it afterwards using hwrm_req_drop(). The caller is no longer required to explicitly hold the hwrm_cmd_lock mutex to read the response. 5. Because the firmware commands and responses all have different sizes, some safeguards are added to the code. This patch maintains legacy API compatibiltiy, implementing the old API in terms of the new. The follow-on patches will convert all callers to use the new APIs. v2: Fix redefined writeq with parisc .config Fix "cast from pointer to integer of different size" warning in hwrm_calc_sentinel() Signed-off-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2021-08-30bnxt_en: Refactor the HWRM_VER_GET firmware callsEdwin Peer
Refactor the code so that __bnxt_hwrm_ver_get() does not call bnxt_hwrm_do_send_msg() directly. The new APIs will not expose this internal call. Add a new bnxt_hwrm_poll() to poll the HWRM_VER_GET firmware call silently. The other bnxt_hwrm_ver_get() function will send the HWRM_VER_GET message directly with error logs enabled.

2021-08-30bnxt_en: remove DMA mapping for KONG responseEdwin Peer
The additional response buffer serves no useful purpose. There can be only one firmware command in flight due to the hwrm_cmd_lock mutex, which is taken for the entire duration of any command completion, KONG or otherwise. It is thus safe to share a single DMA buffer. Removing the code associated with the additional mapping will simplify matters in the next patch, which allocates response buffers from DMA pools on a per request basis.

2021-08-29mwifiex: pcie: add reset_d3cold quirk for Surface gen4+ devicesTsuchiya Yuto
To reset mwifiex on Surface gen4+ (Pro 4 or later gen) devices, it seems that putting the wifi device into D3cold is required according to errata.inf file on Windows installation (Windows/INF/errata.inf). This patch adds a function that performs power-cycle (put into D3cold then D0) and call the function at the end of reset_prepare(). Note: Need to also reset the parent device (bridge) of wifi on SB1; it might be because the bridge of wifi always reports it's in D3hot. When I tried to reset only the wifi device (not touching parent), it gave the following error and the reset failed: acpi device:4b: Cannot transition to power state D0 for parent in D3hot mwifiex_pcie 0000:03:00.0: can't change power state from D3cold to D0 (config space inaccessible) Signed-off-by: Tsuchiya Yuto <kitakar@gmail.com> Signed-off-by: Jonas Dreßler <verdre@v0yd.nl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20210820142050.35741-3-verdre@v0yd.nl

2021-08-29bcma: Fix memory leak for internally-handled coresZenghui Yu
kmemleak reported that dev_name() of internally-handled cores were leaked on driver unbinding. Let's use device_initialize() to take refcounts for them and put_device() to properly free the related stuff. While looking at it, there's another potential issue for those which should be *registered* into driver core. If device_register() failed, we put device once and freed bcma_device structures. In bcma_unregister_cores(), they're treated as unregistered and we hit both UAF and double-free. That smells not good and has also been fixed now.

2021-08-29niu: switch from 'pci_' to 'dma_' APIChristophe JAILLET
In [1], Christoph Hellwig has proposed to remove the wrappers in include/linux/pci-dma-compat.h. Some reasons why this API should be removed have been given by Julia Lawall in [2]. A coccinelle script has been used to perform the needed transformation Only relevant parts are given below. It has been hand modified to use 'dma_set_mask_and_coherent()' instead of 'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable. This is less verbose. Finally, the now useless 'dma_mask' variable has been removed.

2021-08-29octeontx2-pf: Add vlan-etype to ntuple filtersSubbaraya Sundeep
NPC extraction profile marks layer types NPC_LT_LB_CTAG for CTAG and NPC_LT_LB_STAG_QINQ for STAG after parsing input packet. Those layer types can be used to install ntuple filters using vlan-etype option. Below are the commands and corresponding behavior with this patch in place. > alias nt "ethtool -U eth0 flow-type ether" > nt vlan 5 m 0xf000 action 0 Input packets with outer VLAN id as 5 i.e, stag packets with VLAN id 5 and ctag packets with VLAN id as 5 are hit. > nt vlan-etype 0x8100 action 0 All input ctag packets with any VLAN id are hit. > nt vlan-etype 0x88A8 action 0 All input stag packets with any VLAN id are hit. > nt vlan-etype 0x8100 vlan 5 m 0xf000 action 0 All input ctag packets with VLAN id 5 are hit. > nt vlan-etype 0x88A8 vlan 5 m 0xf000 action 0 All input stag packets with VLAN id 5 are hit.

It enables traffic prioritization and bandwidth reservation via the Credit-Based Shaper which is implemented in hardware by i225 controller. Patch 1/3 adds a default cycle-time for TSN mode to be configured. Patch 2/3 helps to separate TSN mode programming on the fly and during reset sequence. It also simplifies handling features flags for various TSN modes supported by i225 in the driver. Patch 3/3 adds support for IEEE802.1Qav(CBS) standard implemented in i225 HW. Two sets of CBS HW shapers are present in i225 and driver enables them in the two high priority queues. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
