2022-04-04drivers/wifi/generic/acpi.c: NULL-check pointers before dereferencingAngel Pons
Checking whether a pointer is NULL after it has been dereferenced makes zero sense. Make sure the `wifi_ssdt_write_properties()` function never gets invoked with a NULL argument for the `dev` parameter, and simplify the logic around the `is_cnvi_ddr_rfim_enabled` variable accordingly.

2022-03-24driver/wifi: Add _DSM method for DDRRFIMVarshit B Pandya
coreboot needs to propagate the CnviDdrRfim value info of the feature enable/disable state into the CNVi via the WiFi DSM ACPI object. This will be consumed by the Wi-Fi driver and it will act according to CB enablement configuration. This patch adds _DSM method for that. Add support for following 2 functions in _DSM method - Function 0: Function Support Query Returns a bitmask of functions supported. - Function 3: RFI enablement 0 Feature Enable 1 Feature Disable Note: Wifi Dsm already has provision for SAR. This patch will add additional support to return RFIM structure based on UUID.

In order to align with established standards for establishing DMA boundaries[1] from ACPI, the UntrustedDevice property has been renamed to DmaProperty, which follows Microsoft's implementation. After discussions with Microsoft, they have agreed to make the `UID` property optional, so it is left out here, and instead it can be applied to: 1) Internal PCI devices 2) PCIe root ports 3) Downstream PCI(e) devices [1]: https://docs.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports BUG=b:215424986 Signed-off-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Change-Id: Id70e916532e3d3d70305fc61473da28c702fc397 Reviewed-on: https://review.coreboot.org/c/coreboot/+/62435 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: EricR Lai <ericr_lai@compal.corp-partner.google.com>
2022-02-07treewide: Remove "ERROR: "/"WARN: " prefixes from log messagesJulius Werner
Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size.

CB:46865 ("mb, soc/intel: Reorganize CNVi device entries in devicetree") reorganized the devicetree entries to make the representation of CNVi device consistent with other internal PCI devices. Since a dummy generic device is added for the CNVi device, `emit_sar_acpi_structures()` needs to first check if the device is PCI before checking the vendor ID. This ensures that SAR table generation is skipped only for PCIe devices with non-Intel vendor IDs and not for the dummy generic device.

This change splits `wifi_generic_fill_ssdt()` into following two functions: 1. `wifi_ssdt_write_device()`: This function writes the device, its address, _UID and _DDN. 2. `wifi_ssdt_write_properties()`: This function writes the properties for WiFi device like _PRW, regulatory domain and SAR. This split is done so that the device write can be skipped for CNVi devices in follow-up CLs. It will allow the SoC controller representation for CNVi PCI device to be consistent with other internal PCI devices in the device tree i.e. not requiring a chip driver for the PCI device.
