2025-05-09wifi: iwlwifi: cfg: move MAC parameters to MAC dataJohannes Berg
There are a number of MAC parameters that are in the iwl_cfg (which is the last config matched to the MAC/RF combination). This isn't necessary, there are many more of those than MACs, so move (most of) the data into the MAC family config struct. Note that DCCM information remains for use by older devices, and on 9000 series it'll be in struct iwl_cfg but be ignored when the CRF is in a Qu/So platform.

2025-05-06wifi: iwlwifi: implement TOP reset followerJohannes Berg
For the upcoming SC hardware, a new reset mode "(silent) TOP reset" will be available. When BT initiates that reset, it'll negotiate with the WiFi firmware which makes it appear to the driver as the reset interrupt. To distinguish it from all the other reasons for the reset interrupt, there's (now) a status field in CSR 0x110. Implement the part of TOP reset where we react to BT doing it. This requires disambiguating the interrupt, depending on the state of the device, since we can even get TOP reset from BT while waiting for the reset handshake. If TOP reset is done by BT while we're not trying to do reset anyway, then simply reprobe, since we cannot keep the state of the device as it's being reset, after waiting the needed 180ms to let the device reset/settle.

2023-04-14wifi: iwlwifi: pcie: work around ROM bug on AX210 integratedJohannes Berg
On 22000 and AX210 devices, there's a ROM bug that causes it to set invalid LTR settings. On 22000 and AX210 non-integrated we can fix up these settings from the driver (as done in the code here), but on AX210 integrated these registers are not available to the driver. Attempt to work around the issue by spinning while the IML is being loaded, the IML will then reprogram the LTR values itself after it's loaded, so only the brief IML load (which the ROM is doing) is affected.

2021-12-07iwlwifi: support 4-bits in MAC step valueMike Golant
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.)

2021-04-14iwlwifi: pcie: clear only FH bits handle in the interruptMordechay Goodstein
For simplicity we assume that msix has 2 IRQ lines one used for rx data called msix_non_share, and another used for one bit flags messages (alive, hw error, sw error, rx data flag) called msix_share. Every time the FW has data to send it puts it on the RX queue and HW turns on the flags in msix_share (inta_fw) indicating about rx data, and HW sends an interrupt a bit later to the msix_non_share _unless_ the msix_shared RX data bit was cleared. Currently in the code every time we get an msix_shared we clear all bits including rx data queue bits. So we can have a race ---------------------------------------------------- DRIVER | HW | FW ---------------------------------------------------- - send host cmd to FW | | | | - handle message | | and put a response | | on the RX queue | - RX flag on | | | - send alive msix | - alive flag on | | - interrupt | | msix_share driver | - handle msix_shared | | and clear all flags | | bits | | | - don't send an | | interrupt on | | msix_non_shared | | (driver cleared) | - driver timeout on | | waiting for host cmd | | respond | | | | ---------------------------------------------------- The change is to clear only the msi_shared flags that are handled in the msix_shared flow, which will cause the hardware to send an interrupt on the msix_non_share line as well, when it has data.

2020-12-10iwlwifi: support firmware reset handshakeJohannes Berg
There are some races in the hardware that can possibly lead to a bus lockup later during a restart when we manage to kill the firmware at a bad time (while it's accessing the bus). To work around this, add support for a new handshake between firmware and driver to ensure that the firmware is in a well- known state before we kill it.

2020-12-10iwlwifi: pcie: remove MSIX_HW_INT_CAUSES_REG_IML handlingJohannes Berg
This is actually wrong, the bit used here by the image loader is BIT(1), not BIT(2). The latter will be reused by the new reset flow soon. However, as we never had any complaints about not printing the IML status or not handling the IML error interrupt (and I suspect the code handling it was incorrectly anyway) just remove the code for it.

On some platforms, the preset values aren't correct and then we may get a completion timeout in the firmware. Change the LTR configuration to avoid that. The firmware will do some more complex reinit of this later, but for the boot process we use ~250usec.

2019-04-29iwlwifi: dbg: replace dump info device family with HW typeShahar S Matityahu
In the dump info, the driver sets device_family to IWL_FW_ERROR_DUMP_FAMILY_7 in case IWL_FW_ERROR_DUMP_FAMILY_7 is used or IWL_FW_ERROR_DUMP_FAMILY_8 otherwise. This information is misleading and incorrect since the driver sets the device family to 8 to any device that is from family 8 and later, e.g. device family 9 is represented as 8 in the dump. Also, the device family enum is known only to the driver and does not give any information to the FW developer Change the device family to HW type to give propper data about the nic in use.
