Add support for collecting and dumping the ring backpressure stats via debugfs. Stats are dumped only if events are received for the specific ring. Below command can be used to obtain these stats as part of soc dp stats. cat /sys/kernel/debug/ath11k/ipq8074/soc_dp_stats Sample Output - When No stats available: Backpressure Stats ================== No Ring Backpressure stats received Sample Output - When ring bp stats available for specific ring Backpressure Stats ================== Ring: REO2SW1_RING count: 1 hp: 2 tp: 2 seen before: 4ms Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01213-QCAHKSWPL_SILICONZ-1 Signed-off-by:

Add support for dp tx error stats which logs tx failure reasons due to ring full condition, etc. This stats is added in soc_dp_stats which was earlier used as soc_rx_stats so that all dp related info are logged in same file.

spectral scan control interface is exposed through debugfs eentry. Relayfs is used to collect the spectral data. These interfaces are similar to ath10k spectral. spectral debugfs interfaces are below, echo background > /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan_ctl echo trigger > /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan_ctl iw dev wlan0 scan echo disable > /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan_ctl cat /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan0 > fft_samples.dump Tested-on: IPQ8074 WLAN.HK.2.1.0.1-01228-QCAHKSWPL_SILICONZ-1 Signed-off-by:

Add direct buffer ring (dbring) with helper API, which is used by the spectral scan. Initialise the direct buffer ring based on the dma ring capability, which get announced in the wmi service ready extended event. This ring is slightly changed from data path rings. Compare to data path ring this ring shares the hp and tp address to firmware though WMI commands. Also the replenish buffer size is derived from firmware announcement. driver receive indication through WMI event WMI_PDEV_DMA_RING_BUF_RELEASE_EVENTID.

xdp_umem.c had overlapping changes between the 64-bit math fix for the calculation of npgs and the removal of the zerocopy memory type which got rid of the chunk_size_nohdr member. The mlx5 Kconfig conflict is a case where we just take the net-next copy of the Kconfig entry dependency as it takes on the ESWITCH dependency by one level of indirection which is what the 'net' conflicting change is trying to ensure.

Yes, staying withing 80 columns is certainly still _preferred_. But it's not the hard limit that the checkpatch warnings imply, and other concerns can most certainly dominate. Increase the default limit to 100 characters. Not because 100 characters is some hard limit either, but that's certainly a "what are you doing" kind of value and less likely to be about the occasional slightly longer lines. Miscellanea: - to avoid unnecessary whitespace changes in files, checkpatch will no longer emit a warning about line length when scanning files unless --strict is also used - Add a bit to coding-style about alignment to open parenthesis Signed-off-by:

If a 6 GHz channel exists, then we can probably safely assume that the device actually supports it, and then it should support most bandwidths. This will probably need to be extended to check the interface type and then dig into the HE capabilities for that though, to have the correct bandwidth check.

An AP supporting EMA (Enhanced Multi-BSSID advertisement) should set bit 83 in the extended capabilities IE (9.4.2.26 in the 802.11ax D5 spec). So the *3rd* bit of the 10th byte should be checked. Also, in one place, the wrong byte was checked. (cfg80211_find_ie returns a pointer to the beginning of the IE, so the data really starts at ie[2], so the 10th byte should be ie[12]. To avoid this confusion, use cfg80211_find_elem instead). Signed-off-by:

If the AP advertises inconsistent data, namely it has CCFS1 or CCFS2, but doesn't advertise support for 160/80+80 bandwidth or "Extended NSS BW Support", then we cannot use any MCSes in the the higher bandwidth. Thus, avoid connecting with higher bandwidth since it's less efficient that way.

These capabilities cover what would otherwise be transported in HT/VHT capabilities, but only a subset thereof that is actually needed on 6 GHz with HE already present. Expose the capabilities to userspace, drivers are expected to set them as using the 6 GHz band (currently) requires HE capability.
