* [PATCH 03/18] wifi: mt76: mt7925: add MT7927 CBTOP remap and chip initialization

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
The MT7927 combo chip has an additional bus fabric called CBInfra
(ConnectaBus Infrastructure) between PCIe and the WiFi subsystem.
Without configuring the CBTOP address remap, all MMIO reads to WiFi
registers return zero.
Add mt7927_cbtop_remap() to configure the PCIe address mapping for WiFi
and Bluetooth subsystems, and mt7927_chip_init() to perform the CBInfra
initialization sequence:
1. EMI sleep protect enable
2. WF subsystem reset via CBInfra RGU
3. MCU ownership acquisition
4. Poll ROMCODE_INDEX for MCU idle (0x1D1E)
5. MCIF remap for host DMA
6. PCIe sleep disable
Skip the early CLR_OWN in probe for MT7927 since CBTOP remap is not yet
configured at that point - the ROM's WFDMA init would fail.
Register values derived from Loong0x00's reverse-engineered MT7927
driver.

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
MT7927 uses different DMA ring indices than MT7925:
- RX MCU events: ring 6 (MT7925 uses ring 0)
- RX data: ring 4 (MT7925 uses ring 2)
- RX auxiliary: ring 7 (management frames)
- TX rings are identical
Add mt7927_dma_init() with the correct ring allocation, a dedicated
mt7927_irq_map with matching interrupt enable bits (BIT(12), BIT(14),
BIT(15) for RX rings 4, 6, 7), and MT7927 packed prefetch register
configuration in mt792x_dma_prefetch().
The DMA init performs a controlled SET_OWN/CLR_OWN sequence after CBTOP
and CBInfra initialization, since CLR_OWN triggers the ROM to initialize
WFDMA.
Ring layout and prefetch values derived from Loong0x00's
reverse-engineered MT7927 driver.

On MT7927 hardware, every CLR_OWN triggers the ROM bootloader to
reinitialize the WFDMA engine, destroying all DMA ring configuration
(base addresses, prefetch settings, descriptor pointers).
The DMA rings are already properly initialized by mt7927_dma_init()
which performs a controlled CLR_OWN before ring setup. Skip the
SET_OWN/CLR_OWN cycle in mt7925e_mcu_init() to preserve that
configuration.

* [PATCH 06/18] wifi: mt76: mt7925: add MT7927 power management, DBDC, and CNM fixes

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
Three MT7927-specific fixes for WiFi functionality:
1. Disable runtime PM: Every CLR_OWN triggers the ROM to reinitialize
WFDMA, destroying DMA ring configuration. Disable PM until the wake
path properly handles MT7927.
2. Enable DBDC (dual-band): MT7927 firmware defaults to single-band
(2.4GHz only). MT7925 firmware handles DBDC automatically, but
MT7927 requires an explicit MCU_UNI_CMD(SET_DBDC_PARMS) with
mbmc_en=1. Without this, 5GHz scan requests are silently discarded.
3. Force CNM capability: MT7927 firmware lacks the connac2 feature
trailer, causing mt792x_get_mac80211_ops() to replace channel
context operations with emulated stubs. This prevents ROC (remain
on channel) before authentication, causing auth frames to be
silently dropped. Force the CNM flag and restore mt7925_ops.

The mac_reset and resume paths use the hardcoded MT_INT_RX_DONE_ALL
constant (bits 0-2) to re-enable RX interrupts. This is correct for
MT7925 (RX rings 0, 1, 2) but wrong for MT7927 which uses RX rings 4, 6,
7 (bits 12, 14, 15).
Replace with the per-chip irq_map fields so the correct interrupt bits
are enabled regardless of the chip variant.

On MT7927 hardware, the mac_reset path performs CLR_OWN and WPDMA logic
reset, both of which destroy DMA ring configuration. CLR_OWN triggers
the ROM to reinitialize WFDMA, and the logic reset pulse disrupts the
WFDMA state that mt7927_dma_init() carefully configured.
A full MT7927 reset requires re-running the DMA initialization sequence,
which is not yet implemented in the recovery path. Return -EOPNOTSUPP
with a warning so users know to reload the module.

The sta_rec_eht structure has a mcs_map_bw320 field, and the channel
width mapping includes NL80211_CHAN_WIDTH_320, but the 320MHz MCS/NSS
map was never copied from the station's EHT capabilities to the MCU TLV.
This prevents negotiation of 320MHz channel width even when both the
hardware and firmware advertise support for it.
Add the missing memcpy for the 320MHz MCS map, matching the existing
pattern for BW20, BW80, and BW160.

* [PATCH 10/18] wifi: mt76: mt7925: enable MT7927 runtime power management

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
Add MT7927-specific GLO_CFG register programming to mt792x_dma_enable()
so that ADDR_EXT_EN and CSR_LBK_RX_Q_SEL_EN are correctly configured
after every WPDMA reinitialization triggered by CLR_OWN during power
management transitions.
On MT7927, every CLR_OWN causes the ROM to reinitialize WFDMA, which
resets the DMA configuration. The PM wake path already handles ring
reprogramming (mt76_queue_reset restores ring base addresses from
stored desc_dma) and prefetch configuration (mt792x_dma_prefetch has
an is_mt7927 branch), but two GLO_CFG bits were missing from
mt792x_dma_enable:
- BIT(26) ADDR_EXT_EN: extended DMA addressing, required for
MT7927's host memory access
- BIT(20) CSR_LBK_RX_Q_SEL_EN: loopback RX queue select, must
be cleared for normal DMA operation
Also define proper macros for these bits and use them in
mt7927_dma_init() to replace bare BIT() values.
With the DMA recovery path now fully MT7927-aware, remove the
is_mt7927() guard that disabled runtime PM and deep sleep. Let the
standard mt792x power management work for MT7927 hardware.

* [PATCH 11/18] wifi: mt76: mt7925: fix uninitialized is_mt7927_hw in probe

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
is_mt7927_hw was declared at the top of mt7925_pci_probe() but only
assigned after its first use at the irq_map selection. The uninitialized
value (typically zero on x86_64) caused the mt7925 IRQ map to be selected
instead of mt7927_irq_map. With the wrong map the driver polls RX rings
0/2 instead of 4/6/7, so MCU responses are never received and every
command times out with "Failed to get patch semaphore".
Fix by initializing is_mt7927_hw at declaration from pdev->device.
Also remove a stale MT_WFDMA0_GLO_CFG_EXT1 define that pointed to the
wrong register address (MT_WFDMA0 base 0xd4000 instead of MT_UWFDMA0
base 0x24000). The correct BIT(28) write is already handled by
mt792x_dma_enable() via MT_UWFDMA0_GLO_CFG_EXT1.

* [PATCH 12/18] wifi: mt76: mt7925: advertise EHT 320MHz capabilities for 6GHz band

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
mt7925_init_eht_caps() only populates EHT MCS/NSS maps for BW <= 80
and BW = 160, but never sets BW = 320. This means iw phy shows no
320MHz MCS map entries even though the hardware supports 320MHz
operation in the 6GHz band.
Add the missing 320MHz capability bits for 6GHz, following the same
pattern as mt7996:
- PHY_CAP0: IEEE80211_EHT_PHY_CAP0_320MHZ_IN_6GHZ
- PHY_CAP1: beamformee SS for 320MHz
- PHY_CAP2: sounding dimensions for 320MHz
- PHY_CAP6: MCS15 support for 320MHz width
- PHY_CAP7: non-OFDMA UL MU-MIMO and MU beamformer for 320MHz
- MCS/NSS: populate bw._320 maps for 6GHz band
Guard all 320MHz capability advertisements behind is_mt7927() since
320MHz support has only been validated on MT7927 hardware. The mt7925
standalone chip may not support 320MHz operation.

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
mt7927_dma_init() sets FW_DWLD_BYPASS_DMASHDL (BIT(9) of GLO_CFG)
during initial probe, but mt792x_dma_enable() - called on every PM
wake cycle - did not restore it. On MT7927, every CLR_OWN causes the
ROM to reinitialize WFDMA which resets GLO_CFG. The PM wake path
already restores ADDR_EXT_EN and clears CSR_LBK_RX_Q_SEL_EN but was
missing FW_DWLD_BYPASS_DMASHDL.
Add FW_DWLD_BYPASS_DMASHDL to the existing is_mt7927() block in
mt792x_dma_enable() so all three MT7927-specific GLO_CFG bits are
consistently restored after PM wake.

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
MT7927 (MT7927) exhibits severe throughput degradation when PCIe ASPM
L1 is active. Upload throughput drops from 1+ Gbps to ~200 Mbps, and
intermittent download drops to ~69 Mbps have been observed.
The root cause is that MT7927's CONNINFRA power domain and WFDMA
register access are unreliable when the PCIe link transitions in and
out of L1 sleep state. Unlike MT7925, MT7927 depends on CONNINFRA
being continuously accessible for CBTOP address remap, and its ROM
reinitializes WFDMA on every CLR_OWN which can race with L1
transitions.
Disable ASPM unconditionally for MT7927 at probe time using the
existing mt76_pci_disable_aspm() helper, which handles both the device
and parent bridge. This disables L0s in addition to L1; L0s power
savings are negligible for a PCIe WLAN card and this avoids needing a
separate L1-only code path with CONFIG_PCIEASPM fallback handling.
After the disable, mt76_pci_aspm_supported() returns false so the
2-3 ms delay in __mt792xe_mcu_drv_pmctrl() is correctly skipped.
The pci_disable_link_state() call persists across suspend/resume.

* [PATCH 15/18] wifi: mt76: mt7925: handle 320MHz bandwidth in RXV and TXS

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
The RX vector (RXV) and TX status (TXS) parsing in mac.c lack handling
for 320MHz channel width. When the hardware reports 320MHz in the
bandwidth field, mt7925_mac_fill_rx_rate() returns -EINVAL and
mt7925_mac_add_txs_skb() records no bandwidth stats.
Add IEEE80211_STA_RX_BW_320 cases to both functions. The RXV parser
also handles BW_320+1 since the hardware can report 320MHz in two
adjacent encoding positions.
Also fix whitespace alignment in mt792x_regs.h defines.

In the error path of mt7925_change_vif_links(), the free: label iterates
over link_ids to clean up, but compares against `mconf` and `mlink`
which hold stale values from the last loop iteration rather than the
current link_id being freed.
Use array-indexed access (mconfs[link_id] / mlinks[link_id]) to compare
against the correct per-link pointers.

* [PATCH 17/18] wifi: mt76: mt7925: fix MT7927 band_idx for stable 5GHz/6GHz operation

In-Reply-To: <20260306-mt7927-wifi-support-v1-0-c77e7445511d@jetm.me>
The MT7927 (Filogic 380) firmware requires explicit band_idx assignment
(0 for 2.4GHz, 1 for 5GHz/6GHz) instead of 0xff (auto-select) used by
MT7925. Without this, the firmware selects the wrong radio for 5GHz and
6GHz connections, causing WPA 4-way handshake timeout and data plane
failures on those bands.
Add mt7925_mt7927_hw_band_from_nl() helper to map nl80211_band to
hardware band index, and use it throughout the driver:
- mac_link_bss_add: set band_idx from link channel at BSS creation
- assign_vif_chanctx: update band_idx when channel context changes,
resend DEV_INFO to firmware if band changed
- bss_basic_tlv: set band_idx in BSS info sent to firmware
- set_roc / set_mlo_roc / abort_roc: send concrete dbdcband instead
of 0xff auto-select
- roc_iter / roc_handle_grant: clamp invalid grant band_idx values
using rfband as fallback, process grants for all MT7927 request
types (not just JOIN)
All changes guarded by is_mt7927() - no impact on MT7925 behavior.
Originally discovered and fixed by marcin-fm; Loong0x00 contributed
additional improvements based on marcin-fm's patch.

* [PATCH 18/18] wifi: mt76: mt7925: add 320MHz bandwidth to bss_rlm_tlv

bss_rlm_tlv() in mt7925_mcu_bss_rlm_tlv() has no case for
NL80211_CHAN_WIDTH_320. When associated to a 320MHz BSS, the switch
falls through to default and sends bw=0 (CMD_CBW_20MHZ) to firmware
via BSS_RLM TLV. Firmware then configures the RX radio for 20MHz
and cannot decode the AP's 320MHz frames, resulting in complete data
path failure at 320MHz.
Add the missing NL80211_CHAN_WIDTH_320 case with CMD_CBW_320MHZ and
center_chan2.
Tested on ASUS RT-BE92U: 320MHz throughput goes from 0 Mbps to
841 Mbps (iperf3 -t30 -P8), PHY 4803 Mbps EHT-MCS11.

Hi Nick,
Thanks for the detailed report this is very helpful. I don't have an
MT7925 USB device to detail look into the issue, but based on the
trace I wrote a small change to try a different MT7925 reset sequence.
please help test.

The patchset should be ordered so that common changes (e.g., enabling
320 MHz support) are added first,
while chip-specific changes are introduced later (e.g.,
MT7927-specific IRQ, DMA, and hardware initialization sequences).
Before introducing chip-specific logic, try to make the functions
generic enough so that other chips can reuse them in the same way.
Checks such as is_mt7927 and duplicated function should only be added
if they cannot be avoided
The more code we can reuse across chips, the fewer maintenance
concerns there will be, and we can focus more effort on the
chip-specific parts.
Please reorganize the patchset order as follows:
1. Common patches that can be reused by other chipsets (now or in the
future) should come first we don't need to mention mt7927
"wifi: mt76: mt7925: fix stale pointer comparisons in change_vif_links"
"wifi: mt76: mt7925: add 320MHz bandwidth to bss_rlm_tlv"
"wifi: mt76: mt7925: handle 320MHz bandwidth in RXV and TXS"
"wifi: mt76: mt7925: populate EHT 320MHz MCS map in sta_rec"
"wifi: mt76: mt7925: advertise EHT 320MHz capabilities for 6GHz band"
Here we can add a helper like is_320MHz_supported() and then advertise
EHT 320MHz capabilities, but do not need to mention is_mt7927() yet.
2. Then introduce MT7927-related changes
wifi: mt76: mt7925: add MT7927 chip ID helpers
Keep the MCU part of "wifi: mt76: mt7925: add MT7927 firmware paths
and PCI device IDs" but leave enabling the PCI device table for the
last patch.
3. IRQ handling
Combine
wifi: mt76: mt7925: use irq_map fields instead of MT_INT_RX_DONE_ALL
the IRQ part of wifi: mt76: mt7925: add MT7927 DMA ring layout, IRQ
map, and prefetch
into one patch about irq_map handling, trying to reuse mt7925_irq as
much as possible.
4. DMA handling
Combine
the DMA part of "wifi: mt76: mt7925: add MT7927 DMA ring layout, IRQ
map, and prefetch"
"wifi: mt76: mt7925: restore FW_DWLD_BYPASS_DMASHDL in MT7927 PM wake path"
into one patch about DMA handling, trying to reuse mt7925_dma_init as
much as possible.
5. Hardware initialization
Combine
"wifi: mt76: mt7925: add MT7927 CBTOP remap and chip initialization"
"wifi: mt76: mt7925: fix uninitialized is_mt7927_hw in probe"
"wifi: mt76: mt7925: skip CLR_OWN in mt7925e_mcu_init for MT7927"
"wifi: mt76: mt7925: add MT7927 power management, DBDC, and CNM fixes"
into one or more patches focused on pure hardware initialization in
logical order. If the register definition is used by MT7927, add
MT7927_ as the prefix.
6. Band index fix
"wifi: mt76: mt7925: fix MT7927 band_idx for stable 5GHz/6GHz operation"
This is worth introducing helper functions and using them instead of
implementing the logic inline.
7. Low power support
Combine
"wifi: mt76: mt7925: enable MT7927 runtime power management"
"wifi: mt76: mt7925: disable ASPM for MT7927 to fix throughput collapse"
into one or more patches related to enabling or disabling low power support.
8. Final patch
The last patch should enable the MT7927 PCI device table.

* [PATCH mt76] wifi: mt76: mt7996: Switch deflink to seclink only if link lookup does not fail

Do not switch default link to the secondary link in
mt7996_mac_sta_remove_links routine if the lookup for the secondary
msta_link fails.
