* rtwn: add rtwn_efuse_prereadAhmad Khalifa2026-08-232-0/+2
| | | | | | | This would be used to switch to the "WiFi bank" before reading the rom. The 8723bu will need this, currently a nop on all chips. Differential Revision: https://reviews.freebsd.org/D59106
* rtwn: fix builds on non-x86 platformsAdrian Chadd2024-12-311-0/+2
| | | | | The powerpcspe build is spitting out uint64_t != unsigned long, so this fails. Comment out the logging for now to unbreak the build.
* rtwn: enable periodic TX reporting support on RTL8188EU NICs.Adrian Chadd2024-12-315-2/+118
| | | | | | | | | | | | | | | | | | | | | | | | | The RTL8188E firmware doesn't have the "full" offload firmware rate control. Instead, the vendor driver has a bunch of logic in the driver for rate probing and selection. Part of this is the periodic TX report - which uploads a summary of multi-rate retries and drops per MAC. Using it drastically cuts down on the TX notifications - it's fired from a timer (defaulting to ~ 1.6 seconds) and is a single receive frame in the normal bulk RX path. I've not ported / reimplemented the whole vendor driver rate adaption code - instead, I'm just using the normal net80211 rate control APIs. It seems to behave OK - I get 25-30mbit down and 20mbit up using TCP/ speedtest.

* rtwn: create a new HAL routine for enabling STA mode beacon processingAdrian Chadd2024-12-204-0/+15
| | | | | | | | | | | | | | | | | | | | | | For some NICs (notably the rtl8192cu that I'm working on) the firmware rate adaptation requires beacon processing to be enabled. Instead of making assumptions in the if_rtwn beacon routines (and honestly all of that should be in the HAL too), create a HAL method for enabling/disabling beacon processing specifically in STA mode. Since this isn't necessarily required for all NICs (notably the RTL8188E NICs, where some will do firmware rate control and some will require driver rate control), only enable it for the RTL8192CU and RT8192EU. The RTL8188E and RTL8812/RTL8821 just have no-op routines for now. Locally tested: * RTL8192CU, STA mode Differential Revision: https://reviews.freebsd.org/D48066 Reviewed by: bz
* rtwn: try enforcing net80211 regulatory / txpower limits for 11n chipsAdrian Chadd2024-12-183-6/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an attempt to reverse engineer what the actual transmit power calculations are doing and apply net80211 limits on them. It doesn't look as simple as just applying the check at the end - there are plenty of places where offsets are calculated between different PHY modes and 1 / 2 antenna MCS transmit rates. There are also some places where the offset being added is negative, so handle the potential underflow so when things hit 0, they don't just wrap and cause the maximum transmit power into the registers. This is being done to aide in power/performance debugging - if there are issues with the transmit power being wrongly calculated and are too high, the output waveform will be distorted and it will effect performance. Being able to drop the transmit power by a few dB here and there can quickly identify if this is happening (because suddenly higher MCS rates / OFDM rates suddenly work better!) I've tested each NIC through the transmit power values from 0 dBm to 30dBm via ifconfig (and they're all capped far before that, normally around 20-25dBm) and they're not underflowing.

* rtwn: add APIs for setting transmit powerAdrian Chadd2024-12-182-0/+2
| | | | | | | | | | | | | | The RTL8188/RTL8192/RTL8821/RTL8812 NICs all seem happy to have their transmit power changed at runtime - and it does seem to do what's expected - the transmit power level does change. So, add the API call here, even though it's all currently no-ops. A follow-up commit will land changes for the chipsets to both limit transmit power to the configured / regulatory limit AND allow reconfiguration at runtime.

* rtwn: add placeholder for the per-MACID rate reportAdrian Chadd2024-12-073-1/+4
| | | | | | | | | | | | | | Some chipsets (such as the RTL8188E) have firmware which supports a second kind of TX report - instead of a per-packet TX report, it can generate a per-MACID summary of packet success/failure counters. This would be helpful for those chips to cut back on the USB traffic to get rate control feedback for the driver based rate control we're currently using. This is a no-op; it just gets the pieces in place for future work. Differential Revision: https://reviews.freebsd.org/D47894

| | | | | | | | | | | | | While IEEE80211_R_BAND was defined, there was no place to store the band. Add a field for that, adjust ieee80211_lookup_channel_rxstatus() to require it, and update drivers passing "R_{FREQ|IEEE}" in already to provide the band as well.
