This commit marks all smd.c functions that are only used inside of smd.c as static. Previous commits added some VHT specific setup functions non-static which is the right thing to do in terms of having granular git commits that compile warning free. What we really want is for local not global scope on those functions. This patch makes the conversion from global to local scope. Signed-off-by:

This patch adds ieee802.11 VHT flags for the wcn3680b. - RX_STBC1 - SU Beamformee - MU Beamformee - VHT80 SGI - Single spatial stream RX LDPC is declared as supported in the datasheet but not enabled at this time. After this patch is applied an AP should see the wcn3680 as an 802.11ac capable device. Signed-off-by:

This commit adds VHT rates to the wcn36xx_update_allowed_rates() routine. Thus allowing the driver to latch the declared rates and transmit them to the firmware in the same way as other 80211.n rates are. Signed-off-by:

In order to send VHT parameters to wcn3680 we need to pass the extended V1 parameter structures to the firmware. These commands need to have the version number set to 1. This patch makes the conversion. The conversion consists of 1. Setting the version number for wcn3680 or leaving it at 0 otherwise 2. Setting the size of the packet header lower for wcn3620 and wcn3660 Once done all three chips can continue to use the same code to pass parameters to their respective firmware. In the case of the wcn3680 the passed structures will be slightly larger to accommodate communication of VHT descriptors. Signed-off-by:

In order to pass 802.11ac VHT parameters from the SoC to wcn36xx we need to use the V1 data structures associated with BSS and STA parameters. The means of identifying a V1 data-structure is via the SMD version field. This patch defines a INIT_HAL_MSG_V1() which operates the same way as INIT_HAL_MSG() with the exception that it defines VERSION1 as opposed to VERSION0. Signed-off-by:

This commit makes use of wcn36xx_smd_set_bss_vht_params() to extract VHT parameters from the 80211_sta structure and latch appropriate bits in the bss_params_v1 structure for transmission to the wcnss firmware. Signed-off-by:

This commit modifies wcn36xx_smd_start() so that it can download wcn3680 specific firmware parameters if we are talking to the wcn3680. If not the original generic firmware parameter table should continue to be used for wcn3620 and wcn3660. Signed-off-by:

This commit defines a firmware configuration for the wcn3680 which represents a working downstream configuration. This configuration has been successfully applied to the upstream driver with antecedent patches resulting in the same or better through-put in comparison to the downstream driver on the test hardware.

In order to get 802.11ac working the way we want, additional parameters need to be passed down to the firmware. This patch takes the full remaining set of parameters defined in the downstream riva/inc/wlan_hal_cfg.h and imports them into hal.h with some minor name length adjustments. This addition will allow us to pass a larger firmware configuration set later on. Signed-off-by:

Board Data File (BDF) is loaded upon driver boot-up procedure. The right board data file is identified using bus and qmi-board-id. The problem, however, can occur when the (default) board data file cannot fulfill with the vendor requirements and it is necessary to use a different board data file. Also using the chip_id for identifying the board data helps in dealing with different variants of the board data file based on the RF card. If the chip_id is not programmed, a default value of 0xff will be used for parsing the board data file. Add the support to get the variant field from DTSI and use this information along with the chip_id to load the vendor specific BDF. The device tree requires addition strings to define the variant name wifi@a000000 { status = "okay"; qcom,ath10k-calibration-variant = "xyz-v2"; }; wifi@a800000 { status = "okay"; qcom,ath10k-calibration-variant = "xyz-v1"; }; This would create the boarddata identifiers for the board-2.bin search * bus=snoc,qmi-board-id=16,qmi-chip-id=0,variant=xyz-v1 * bus=snoc,qmi-board-id=17,qmi-chip-id=0,variant=xyz-v2 Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.1-01040-QCAHLSWMTPLZ-1 Signed-off-by:Rakesh Pillai <pillair@codeaurora.org> Signed-off-by:

wcn36xx_smd_config_bss_v0() and wcn36xx_smd_config_bss_v1() have been designed to operate in standalone fashion. As a result we can drop the dead code now present in wcn36xx_smd_config_bss() and happily remove one kzalloc from the BSS config path as we do so. Signed-off-by:

Bryan O'Donoghue authored
This patch updates wcn36xx_smd_config_bss_v1() to update on internally derived parameters only, specifically making use of STA v1 wrapper routines previously added. Once done we no longer need to pass a struct wcn36xx_hal_config_bss_req_msg which gives us options in later patches to eliminate the kzalloc() in wcn36xx_smd_config_bss entirely. Signed-off-by:

This commit adds wcn36xx_smd_set_bss_vht_params(). The job of this function is to decide if the BSS is VHT capable and if so set the appropriate bit in the BSS parameter structure for passing to the firmware. VHT Channel width set is not set since we don't support 160MHz. Signed-off-by:

This patch converts the internal data structure used to store data-rates from version 0 to version 1. This allows us to extend out the internal storage to represent VHT parameters. Using the extended version 1 data-structure allows us to avoid a whole raft of version 1 specific fixup functions. Signed-off-by:

Bryan O'Donoghue authored
In order to pass VHT parameters to wcn3680 we need to use a super-set of the V1 data-structures with additional VHT parameters tacked on. This patch adds the additional fields to the STA and BSS parameter structures. Since neither wcn3620 nor wcn3660 support VHT the size of the passed message is fixed to the previous message length. Subsequent changes will differentiate between wcn3620/wcn3660 and wcn3680 which does use the larger message size. Signed-off-by:

Calls to usb_kill_anchored_urbs() after usb_kill_urb() on multiprocessor systems create a race condition in which usb_kill_anchored_urbs() deallocates the URB before the completer callback is called in usb_kill_urb(), resulting in a use-after-free. To fix this, add proper lock protection to usb_kill_urb() calls that can possibly run concurrently with usb_kill_anchored_urbs().

Rather than doing request_irq and then disabling the irq immediately, it should be safer to use IRQ_NOAUTOEN flag for the irq. It removes any gap between request_irq() and disable_irq(). Cc: Salil Mehta <salil.mehta@huawei.com> Reviewed-by:

Grygorii Strashko says: ==================== net: ethernet: ti: ale: add static configuration As existing, as newly introduced CPSW ALE versions have differences in supported features and ALE table formats. Especially it's actual for the recent AM65x/J721E/J7200 and future AM64x SoCs, which supports more features like: auto-aging, classifiers, Link aggregation, additional HW filtering, etc. The existing ALE configuration interface is not practical in terms of adding new features and requires consumers to program a lot static parameters. And any attempt to add new features will case endless adding and maintaining different combination of flags and options. Because CPSW ALE configuration is static and fixed for SoC (or set of SoC), It is reasonable to add support for static ALE configurations inside ALE module. This series introduces static ALE configuration table for different ALE variants and provides option for consumers to select required ALE configuration by providing ALE const char *dev_id identifier (Patch 2). And all existing driver have been switched to use new approach (Patches 3-6). After this ALE HW auto-ageing feature can be enabled for AM65x CPSW ALE variant (Patch 7). Finally, Patches 8-9 introduces tables to describe the ALE VLAN entries fields as the ALE VLAN entries are too much differ between different TI CPSW ALE versions. So, handling them using flags, defines and get/set functions are became over-complicated.

The ALE VLAN entries are too much differ between different TI CPSW ALE versions. So, handling them using flags, defines and get/set functions became over-complicated. This patch introduces tables to describe the ALE VLAN entries fields, which are different between TI CPSW ALE versions, and new get/set access functions. It also allows to detect incorrect access to not available ALL entry fields. Signed-off-by:
