2023-08-01wifi: rtw89: add to display hardware rates v1 histogram in debugfsPing-Ke Shih
The upcoming WiFi 7 chips support EHT rates, and hardware rate codes are changed too, so modify to adapt the changes. (EHT counters are still zeros in below example) RX count: Legacy: [0, 0, 0, 0] OFDM: [0, 0, 0, 0, 0, 0, 0, 0] HT 0: [0, 0, 0, 0, 0, 0, 0, 0] HT 1: [0, 0, 0, 0, 0, 0, 0, 0] VHT 1SS: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0][0, 0] VHT 2SS: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0][0, 0] HE 1SS: [0, 0, 42, 0, 43, 90, 75, 0, 26, 20, 260, 7] HE 2SS: [0, 96, 232, 84, 125, 184, 52, 0, 0, 0, 0, 0] EHT 1SS: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0][0, 0] EHT 2SS: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230728070252.66525-10-pkshih@realtek.com
2023-08-01wifi: rtw89: add C2H RA event V1 to support WiFi 7 chipsPing-Ke Shih
WiFi 7 chips have more rate mode (EHT), higher MCS and more bandwidth, so define and use reserved bits to carry these information in C2H events. Also, the SS/MCS encoded bits of VHT and HE are changed, so define V1 masks for them.

2023-08-01wifi: rtw89: add H2C RA command V1 to support WiFi 7 chipsPing-Ke Shih
H2C RA V1 command adds two words to support WiFi 7 chips, which can possibly support up to 4SS rates. Because current chips have only 2SS rates, leave the fields blank for now. The main changes are to set extended bits of EHT mode and bandwidth -- add a bit for EHT mode; add a bit to enumerate 320MHz channel bandwidth.

2023-08-01wifi: rtw89: use struct to set RA H2C commandPing-Ke Shih
RA (rate adaptive) H2C command is used to tell firmware which rates can be used for specified MAC ID. Basically, this commit doesn't change result. Only change to set two 32-bit instead of continual 8-byte rate masks one by one. Originally, we only set 5-byte masks, because existing WiFi 6 2SS chips only need 5-byte masks. Setting two 32-bit masks will be more efficient and also can support coming WiFi 7 2SS chips containing more rates.

2023-08-01wifi: rtw89: Fix loading of compressed firmwareLarry Finger
When using compressed firmware, the early firmware load feature will fail. In most cases, the only downside is that if a device has more than one firmware version available, only the last one listed will be loaded. In at least two cases, there is no firmware loaded, and the device fails initialization. See https://github.com/lwfinger/rtw89/issues/259 and https://bugzilla.opensuse.org/show_bug.cgi?id=1212808 for examples of the failure. When firmware_class.dyndbg=+p" added to the kernel boot parameters, the following is found: finger@localhost:~/rtw89>sudo dmesg -t | grep rtw89 firmware_class: __allocate_fw_priv: fw-rtw89/rtw8852b_fw-1.bin fw_priv=00000000638862fb rtw89_8852be 0000:02:00.0: loading /lib/firmware/updates/5.14.21-150500.53-default/rtw89/rtw8852b_fw-1.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/updates/rtw89/rtw8852b_fw-1.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/5.14.21-150500.53-default/rtw89/rtw8852b_fw-1.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/rtw89/rtw8852b_fw-1.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: Direct firmware load for rtw89/rtw8852b_fw-1.bin failed with error -2 firmware_class: __free_fw_priv: fw-rtw89/rtw8852b_fw-1.bin fw_priv=00000000638862fb data=00000000307c30c7 size=0 firmware_class: __allocate_fw_priv: fw-rtw89/rtw8852b_fw.bin fw_priv=00000000638862fb rtw89_8852be 0000:02:00.0: loading /lib/firmware/updates/5.14.21-150500.53-default/rtw89/rtw8852b_fw.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/updates/rtw89/rtw8852b_fw.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/5.14.21-150500.53-default/rtw89/rtw8852b_fw.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/rtw89/rtw8852b_fw.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: Direct firmware load for rtw89/rtw8852b_fw.bin failed with error -2 firmware_class: __free_fw_priv: fw-rtw89/rtw8852b_fw.bin fw_priv=00000000638862fb data=00000000307c30c7 size=0 rtw89_8852be 0000:02:00.0: failed to early request firmware: -2 firmware_class: __allocate_fw_priv: fw-rtw89/rtw8852b_fw.bin fw_priv=00000000638862fb rtw89_8852be 0000:02:00.0: loading /lib/firmware/updates/5.14.21-150500.53-default/rtw89/rtw8852b_fw.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/updates/rtw89/rtw8852b_fw.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/5.14.21-150500.53-default/rtw89/rtw8852b_fw.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/rtw89/rtw8852b_fw.bin failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/updates/5.14.21-150500.53-default/rtw89/rtw8852b_fw.bin.xz failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/updates/rtw89/rtw8852b_fw.bin.xz failed for no such file or directory. rtw89_8852be 0000:02:00.0: loading /lib/firmware/5.14.21-150500.53-default/rtw89/rtw8852b_fw.bin.xz failed for no such file or directory. rtw89_8852be 0000:02:00.0: Loading firmware from /lib/firmware/rtw89/rtw8852b_fw.bin.xz rtw89_8852be 0000:02:00.0: f/w decompressing rtw89/rtw8852b_fw.bin firmware_class: fw_set_page_data: fw-rtw89/rtw8852b_fw.bin fw_priv=00000000638862fb data=000000004ed6c2f7 size=1035232 rtw89_8852be 0000:02:00.0: Firmware version 0.27.32.1, cmd version 0, type 1 rtw89_8852be 0000:02:00.0: Firmware version 0.27.32.1, cmd version 0, type 3 The key is that firmware version 0.27.32.1 is loaded.

2023-06-21wifi: rtw89: 8851b: rfk: update IQK to version 0x8Ping-Ke Shih
The main change is to adjust RX calibration groups from {0,1,2,3} to {0,2} in 5 GHz, so reduce elements from 4 to 2, and use index to iterate them. Meanwhile, always do RX narrowband calibration (ID_NBRXK) for each group. NCTL is used to assist IQK, so also update NCTL to 0x6 along with internal tag HALRF_029_00_103.

2023-06-21wifi: rtw88: fix not entering PS mode after AP stopsPo-Hao Huang
Without this patch, firmware only track beacons for port 0 and since we will always start AP on port 0, this results in misbehavior of power saving mode on other ports after AP stops. The "default port" H2C command is used to notify which port should firmware track. Update the correct settings to firmware so power saving mode can work properly.

Broadcast and multicast packets in high queue should be transmitted all at once during DTIM. But without proper settings, hardware fails to recognize that there are multiple packets and fetches only one.

2023-06-21wifi: rtw88: process VO packets without workqueue to avoid PTK rekey failedChih-Kang Chang
In the wpa_supplicant rekey flow, it sends an EAPOL packet 4/4 through nl80211_tx_control_port() and triggers wake_tx_queue() in the driver. Then, it sends nl80211_new_key() to configure a new key in mac80211. However, in wake_tx_queue(), a workqueue is used to process the tx packet, which might cause the driver to process the EAPOL packet later than nl80211_new_key(). As a result, the EAPOL 4/4 packet is dropped by mac80211 due to the rekey configuration being finished. The EAPOL packets belongs to VO packets that need high priority. Therefore, we process VO packets directly without workqueue to ensure that packets can process immediately. VO is normally used by voice application that is low traffic load and low latency, that doesn't affect user experience.

2023-06-21wifi: rtw88: Fix action frame transmission fail before associationPo-Hao Huang
For combo chips, antennas were controlled by bluetooth only during power on. If WiFi wish to do transmission, notification to the coexistence module are required. Previously we only do this before authentication. To allow transmission before auth, such as management TX, now we start the initiation of coexistence earlier so antennas are shared between WiFi and bluetooth after set_channel(), and frames could then be sent.
