2024-05-06wifi: iwlwifi: Force SCU_ACTIVE for specific platformsDaniel Gabay1-1/+4
Firmware 0x2F7 assert observed in Dell platforms when using GL HW. This issue is mitigated by setting SCU_FORCE_ACTIVE during platform low power states. Driver shall indicate firmware to force SCU active by setting bit 29 in context info prph scratch control flags. This mitigation is limited to Dell platforms with GL HW only.

Replace the field reduce_power_dram with a struct that holds data about the reduced-power tables drams regions. Generalize load_payloads_segments() to work for both pnvm tables and reduction power tables. Make required adjustments in the data structures.

2023-06-06wifi: iwlwifi: Implement loading and setting of fragmented pnvm imageAlon Giladi1-0/+8
Save the pnvm payloads in several DRAM segments (not only in one as used to). In addition, allocate a FW structure in DRAM that holds the segments' addresses and forward its address to the FW. It's done when FW has the capability to handle pnvm images this way (helps to process large pnvm images).

Take the part that is copying the pnvm image into DRAM, out of the the method that sets the prph_scratch. Makes the code cleaner since those 2 operations don't always happen together (loading should happen only once while setting can happen more than once). In addition, each operation will get more complex in the future when it will support also larger pnvm images.

2023-06-06wifi: iwlwifi: Generalize the parsing of the pnvm imageAlon Giladi1-1/+3
Generalize iwl_pnvm_parse(). This saves us from copying each payload twice (first in the parsing and later when copying it to the dram). Moreover, its more compatible for handling larger pnvm tables in the future (in which payloads won't be concatenated). The main changes are: 1. Take out the concatenating of the payloads from the parsing level 2. Start using iwl_pnvm_image structure that will hold pointers to payloads that should be delivered to fw, their sizes and number.

2021-06-22iwlwifi: support loading the reduced power table from UEFILuca Coelho1-1/+15
This new feature allows OEMs to set a special reduced power table in a UEFI variable, which we use to tell the firmware to change the TX power tables. Read the variable and store it in a dram block to pass it to the firmware. We do this as part of the PNVM loading flow.

2021-06-22iwlwifi: pcie: free some DMA memory earlierJohannes Berg1-2/+2
In gen3, after firmware is alive, we no longer need the firmware and image loader images, only the context info itself and PRPH info/scratch need to remain. Call iwl_pcie_ctxt_info_gen3_free() appropriately in the alive callback (iwl_trans_pcie_gen2_fw_alive()) with a new argument indicating whether it can free everything or only partially. The context info and PRPH scratch are also not needed after PNVM load, but we don't have a good hook for freeing after that, so keep them for now.

In 22560 devices the ROM sendis an interrupt to the host once the IML reading is done. Handle this interrupt, and indicate sw error in case the value is fail.

2018-07-26iwlwifi: pcie: support context information for 22560 devicesGolan Ben Ami1-0/+285
Context information structure was added to 22000 devices for firmware self init. In the next generation of devices the context information changes significantly, and the original context information is divided roughly to three data structures: context information gen3, prph information and prph scratch. In addition, the init flow changes so the firmware is loaded by the IML, and so we must allocate the IML on the DRAM and give the ROM the IML's address before kicking the firmware's self init.
