2025-05-06wifi: iwlwifi: prepare for reading WPFC from UEFIMiri Korenblit
IWL_BIOS_TABLE_LOADER generates the code that determines from what source to read a BIOS table (ACPI or UEFI). As we want to read WPFC from UEFI to, iwl_acpi_get_phy_filters needs to have the prototype that is required by this macro: receive fwrt and return a int on success/failure. Do that. This allowes us to make to version of iwl_acpi_get_phy_filters for non ACPI builds back to an iniline function.

2025-01-13wifi: iwlwifi: implement product reset for TOP errorsJohannes Berg
The TOP is a shared (between BT and WiFi) hardware component, and if it has an error we need to reset the whole device, i.e. both BT and WiFi. This is achieved by calling a specific ACPI DSM (device-specific method) with the right arguments before doing a reset via the object referenced by _PRR. Since this is needed here, but a function reset will always do better than just re-enumerating the bus in case of errors, we can always try to at least do a function reset and do the full product reset only when needed for TOP errors. Also, for some Bz and Sc devices where BT is PCIe/IOSF as well, find the BT device and unbind that device as well so the BT driver can recover from the reset that's going to happen, rather than having to somehow detect that the device was reset. Also add - currently unused - the function reset mode, this is going to get used in the upcoming escalation model.

2024-02-02wifi: iwlwifi: simplify getting DSM from ACPIMiri Korenblit
As DSMs are going to be read from UEFI too, we need a unified API to get DSMs for both ACPI and UEFI. The difference in getting DSM in each one of these methods (ACPI, UEFI) is in the GUID, revision (0 for ACPI, 4 for UEFI), and size of the DSM values (8 or 32 for ACPI, 32 for UEFI). Therefore, change the iwl_acpi_get_dsm_x() to iwl_acpi_get_dsm() which determines the GUID, revision (these two are the same for all WiFi DSMs), and size (based on a func-to-size mapping) internally. While at it, fix DSM_FUNC_RFI_CONFIG to expect a 32-bit value (as defined in Intel BIOS spec) and not a 8-bit one.

There's a new revision of the WGDS table with more data, and corresponding firmware API to pass it through. Add support for both. Since we now support 4 different versions, make a table to load them instead of hard-coding it all.

2021-08-26iwlwifi: convert flat GEO profile table to a struct versionLuca Coelho
The GEO profiles have been stored in single-dimension arrays and the access has been done via a single index. We will soon need to support different revisions of this table, which will make the flat array even harder to handle. To prepare for that, convert the single-dimension array to a struct with substructures.

As an extension to the WRDS support for revisions 1 and 2, do the same for the EWRD tables. These tables have a very similar format to the WRDS table, so most of the code is similar.

2021-08-26iwlwifi: acpi: support reading and storing WRDS revision 1 and 2Luca Coelho
Change the SAR profile tables storage to revision 2 regardless of the revision we read from ACPI. Revision 2 is a superset of revision 1, which is in turn a superset of revision 0, so they can all be stored inside revision 2. Add support for reading and storing also revisions 1 and 2, whose only difference is the number of chains and number of sub-bands. So most of the code revolves around passing different chain and sub-band sizes. With this patch we still pass only revision 0 to the firmware, but that will be changed in a separate patch.

This definition was only used to pass the size of the tables in the FW API to the iwl_sar_select_profile() function, but we should actually pass the definition from the FW API file.
