2024-11-07wifi: iwlwifi: be less noisy if the NIC is dead in S3Emmanuel Grumbach
If the NIC is dead upon resume, try to catch the error earlier and exit earlier. We'll print less error messages and get to the same recovery path as before: reload the firmware.

2023-08-22wifi: iwlwifi: remove memory check for LMAC error addressMukesh Sisodiya
LMAC error table address was checked against UMAC error table minimum address defined. Because of that, the LMAC error table was not read, since both addresses belong to different ranges. As addresses are updated from FW alive message and should be correct, this check is not needed. Still keep the check for address 0 to avoid NULL address read.

2023-06-14wifi: iwlwifi: unify checks for HW error valuesJohannes Berg
The hardware, depending on which part fails or times out, returns 0xA5A5A5A. or 0x5A5A5A5. with the lowest 4 bits encoding some further reason/status. However, mostly we don't really need to care about the exact reasons, so unify the checks for this to avoid hardcoding those magic values all over the driver.

2021-12-21iwlwifi: recognize missing PNVM data and then log filenameLuca Coelho
We can detect that a FW SYSASSERT is due to missing PNVM data by checking the assertion code. When this happens, it's is useful for the user if we print the filename where the driver is looking for the data. Add the PNVM missing assertion code to the dump list and print out the name of the file we're looking for when this happens.

2021-12-07iwlwifi: pcie: retake ownership after resetJohannes Berg
In most cases, unless shutting down the NIC, we really need to retake ownership after doing a software reset of the NIC. Encode that into the API so we "automatically" do it, even in case of workarounds, and don't keep forgetting it like a few of the places we have did.
