Kalle Valo says: ==================== wireless-next patches for v6.1 Few stack changes and lots of driver changes in this round. brcmfmac has more activity as usual and it gets new hardware support. ath11k improves WCN6750 support and also other smaller features. And of course changes all over. Note: in early September wireless tree was merged to wireless-next to avoid some conflicts with mac80211 patches, this shouldn't cause any problems but wanted to mention anyway. Major changes: mac80211 - refactoring and preparation for Wi-Fi 7 Multi-Link Operation (MLO) feature continues brcmfmac - support CYW43439 SDIO chipset - support BCM4378 on Apple platforms - support CYW89459 PCIe chipset rtw89 - more work to get rtw8852c supported - P2P support - support for enabling and disabling MSDU aggregation via nl80211 mt76 - tx status reporting improvements ath11k - cold boot calibration support on WCN6750 - Target Wake Time (TWT) debugfs support for STA interface - support to connect to a non-transmit MBSSID AP profile - enable remain-on-channel support on WCN6750 - implement SRAM dump debugfs interface - enable threaded NAPI on all hardware - WoW support for WCN6750 - support to provide transmit power from firmware via nl80211 - support to get power save duration for each client - spectral scan support for 160 MHz wcn36xx - add SNR from a received frame as a source of system entropy * tag 'wireless-next-2022-09-30' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (231 commits) wifi: rtl8xxxu: Improve rtl8xxxu_queue_select wifi: rtl8xxxu: Fix AIFS written to REG_EDCA_*_PARAM wifi: rtl8xxxu: gen2: Enable 40 MHz channel width wifi: rtw89: 8852b: configure DLE mem wifi: rtw89: check DLE FIFO size with reserved size wifi: rtw89: mac: correct register of report IMR wifi: rtw89: pci: set power cut closed for 8852be wifi: rtw89: pci: add to do PCI auto calibration wifi: rtw89: 8852b: implement chip_ops::{enable,disable}_bb_rf wifi: rtw89: add DMA busy checking bits to chip info wifi: rtw89: mac: define DMA channel mask to avoid unsupported channels wifi: rtw89: pci: mask out unsupported TX channels iwlegacy: Replace zero-length arrays with DECLARE_FLEX_ARRAY() helper ipw2x00: Replace zero-length array with DECLARE_FLEX_ARRAY() helper wifi: iwlwifi: Track scan_cmd allocation size explicitly brcmfmac: Remove the call to "dtim_assoc" IOVAR brcmfmac: increase dcmd maximum buffer size brcmfmac: Support 89459 pcie brcmfmac: increase default max WOWL patterns to 16 cw1200: fix incorrect check to determine if no element is found in list ... ==================== Link: https://lore.kernel.org/r/20220930150413.A7984C433D6@smtp.kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-09-28net: drop the weight argument from netif_napi_addJakub Kicinski1-1/+1
We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add().

2022-05-18iwlwifi: pcie: simplify MSI-X cause mappingJohannes Berg1-19/+29
We're currently manually encoding a calculation here since the HW just maps all the bits of specific registers to specific offsets, which led to the bug fixed here previously with the Bz SW_ERROR interrupt. Clean up the code to only know about the mapping offset (-16 or 16 depending on the register) to avoid such issues in the future.

2022-02-18iwlwifi: support new queue allocation commandJohannes Berg1-1/+2
Newer firmware versions will support a new queue allocation command, in order to deal with MLD where multiple stations are used for a single queue. Add support for the new command. This requires some refactoring of the queue allocation API, which now gets - the station mask instead of the station ID - the flags without the "enable" flag, since that's no longer used in the new API Additionally, this new API now requires that we remove queues before removing a station, the firmware will no longer do that internally.

2022-02-18iwlwifi: propagate (const) type qualifierBjoern A. Zeeb2-2/+2
Most of this change is a continuation of commit 403ea939ea6a ("iwlwifi: dbg: Mark ucode tlv data as const") propagating the (const) type qualifier for ucode based tlv data to avoid having the impression that it is writeable. The other part of the change preserves the (const) type qualifier over casts and function calls where it was previously lost. Both changes are needed to avoid compile time errors on system with more strict error settings, in this case found with clang on FreeBSD. Sponsored by: The FreeBSD Foundation Signed-off-by: Bjoern A.

2022-02-18iwlwifi: de-const properly where neededBjoern A. Zeeb2-4/+4
In order to de-const variables simply casting through (void *) is not enough: "cast from 'const .. *' to 'void *' drops const qualifier". Cast through (uintptr_t) as well [1] to make this compile on systems with more strict requirements. In addition passing const void *data to dma_map_single() also drops the (const) qualifier. De-constify on variable on assignment which may be overwritten later. In either case the (void *) cast to dma_map_single() is not needed (anymore) either.

The original implementation checked the HW family, and as a result of that used different addresses for the prph registers. The old HWs addresses start with 0xa****** and the newer ones start with 0xd******. For this there are iwl_read/write_umac_prph functions that just add the diff in the address automatically (in this case 0x300000), so the code will be common for all HWs In the original implementation the address given already had the 0xd****** causing the address to become 0x10***** (after adding the offset) Change the registers to start with 0xa*****.

In most cases, unless shutting down the NIC, we really need to retake ownership after doing a software reset of the NIC.

2021-12-07iwlwifi: support 4-bits in MAC step valueMike Golant2-3/+4
We have a MAC component (which is inside the SoC) and it has several different HW steps. 3 bits used to be enough but now we need 4-bits to represent all the different steps. Properly support 4-bits in the MAC step value by refactoring all the current handling of the MAC step/dash. Already from family 8000 and up the dash (bits 0-1) no longer exists and the step (until 8000 bits 2-3) consists of the dash bits as well. To do this remove the CSR_HW_REV_STEP and the CSR_HW_REV_DASH macros, replace them with CSR_HW_REV_STEP_DASH and add hw_rev_step into the trans struct. In addition remove the CSR_HW_IF_CONFIG_REG_MSK_MAC_STEP and CSR_HW_IF_CONFIG_REG_MSK_MAC_DASH macros and create a new macro combining the 2 (this way we don't need shifting or anything else.)

2021-11-26iwlwifi: integrate with iwlmeiEmmanuel Grumbach2-11/+35
iwlmei needs to know about the follwing events: * Association * De-association * Country Code change * SW Rfkill change * SAR table changes iwlmei can take the device away from us, so report the new rfkill type when this happens. Advertise the required data from the CSME firmware to the usersapce: mostly, the AP that the CSME firmware is currently associated to in case there is an active link protection session. Generate the HOST_ASSOC / HOST_DISSASSOC messages. Don't support WPA1 (non-RSNA) for now. Don't support shared wep either. We can then determine the AUTH parameter by checking the AKM. Feed the cipher from the key installation. SW Rfkill will be implemented later when cfg80211 will allow us to read the SW Rfkill state.

We currently match the list of devices from the start to the end, but then find the *last* match, so we need to look at each and every entry.
