wifi: wcn36xx: Add RX frame SNR as a source of system entropy

2022-09-19T12:42:37Z

The signal-to-noise-ratio SNR is returned by the wcn36xx firmware for each received frame. SNR represents all of the unwanted interference signal after filtering out the fundamental frequency and harmonics of the frequency. Noise can come from various electromagnetic sources, from temperature affecting the performance hardware components or quantization effects converting from analog to digital domains. The SNR value returned by the WiFi firmware then is a good source of entropy. Other WiFi drivers offer up the noise component of the FFT as an entropy source for the random pool e.g. commit 2aa56cca3571 ("ath9k: Mix the received FFT bins to the random pool") I attended Jason's talk on sources of randomness at Plumbers and it occurred to me that SNR is a reasonable candidate to add.

wifi: wcn36xx: Add debugfs entry to read firmware feature strings

2022-07-29T13:24:38Z

Add in the ability to easily find the firmware feature bits reported in the get feature exchange without having to compile-in debug prints. root@linaro-alip:~# cat /sys/kernel/debug/ieee80211/phy0/wcn36xx/firmware_feat_caps MCC P2P DOT11AC SLM_SESSIONIZATION DOT11AC_OPMODE SAP32STA TDLS P2P_GO_NOA_DECOUPLE_INIT_SCAN WLANACTIVE_OFFLOAD BEACON_OFFLOAD SCAN_OFFLOAD BCN_MISS_OFFLOAD STA_POWERSAVE STA_ADVANCED_PWRSAVE BCN_FILTER RTT RATECTRL WOW WLAN_ROAM_SCAN_OFFLOAD SPECULATIVE_PS_POLL IBSS_HEARTBEAT_OFFLOAD WLAN_SCAN_OFFLOAD WLAN_PERIODIC_TX_PTRN ADVANCE_TDLS BATCH_SCAN FW_IN_TX_PATH EXTENDED_NSOFFLOAD_SLOT CH_SWITCH_V1 HT40_OBSS_SCAN UPDATE_CHANNEL_LIST WLAN_MCADDR_FLT WLAN_CH144 TDLS_SCAN_COEXISTENCE LINK_LAYER_STATS_MEAS MU_MIMO EXTENDED_SCAN DYNAMIC_WMM_PS MAC_SPOOFED_SCAN FW_STATS WPS_PRBRSP_TMPL BCN_IE_FLT_DELTA Signed-off-by: Bryan O'Donoghue Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20220727161655.2286867-5-bryan.odonoghue@linaro.org

wifi: wcn36xx: Move capability bitmap to string translation function to firmware.c

wifi: wcn36xx: Move firmware feature bit storage to dedicated firmware.c file

2022-07-29T13:24:38Z

The naming of the get/set/clear firmware feature capability bits doesn't really follow the established namespace pattern of wcn36xx_logicalblock_do_something(); The feature bits are accessed by smd.c and main.c. It would be nice to display the found feature bits in debugfs. To do so though we should tidy up the namespace a bit. Move the firmware feature exchange API to its own file - firmware.c giving us the opportunity to functionally decompose other firmware related accessors as appropriate in future.

wifi: wcn36xx: Rename clunky firmware feature bit enum

2022-07-29T13:24:38Z

The enum name "place_holder_in_cap_bitmap" is self descriptively asking to be changed to something else. Rename place_holder_in_cap_bitmap to wcn36xx_firmware_feat_caps so that the contents and intent of the enum is obvious.

wifi: mac80211: move ps setting to vif config

2022-07-15T09:43:15Z

This really shouldn't be in a per-link config, we don't want to let anyone control it that way (if anything, link powersave could be forced through APIs to activate/deactivate a link), and we don't support powersave in software with devices that can do MLO. Signed-off-by: Johannes Berg
