2023-06-19wifi: iwlwifi: pcie: double-check ACK interrupt after timeoutJohannes Berg
There are evidently cases where the firmware completes the reset but the interrupt isn't received correctly, so check for the interrupt again after the timeout, and don't dump the firmware error log if the right bit is set.

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.

2021-04-06iwlwifi: pcie: properly set LTR workarounds on 22000 devicesJohannes Berg
As the context info gen3 code is only called for >=AX210 devices (from iwl_trans_pcie_gen2_start_fw()) the code there to set LTR on 22000 devices cannot actually do anything (22000 < AX210). Fix this by moving the LTR code to iwl_trans_pcie_gen2_start_fw() where it can handle both devices. This then requires that we kick the firmware only after that rather than doing it from the context info code. Note that this again had a dead branch in gen3 code, which I've removed here.

2019-06-29iwlwifi: fix RF-Kill interrupt while FW load for gen2 devicesEmmanuel Grumbach
Newest devices have a new firmware load mechanism. This mechanism is called the context info. It means that the driver doesn't need to load the sections of the firmware. The driver rather prepares a place in DRAM, with pointers to the relevant sections of the firmware, and the firmware loads itself. At the end of the process, the firmware sends the ALIVE interrupt. This is different from the previous scheme in which the driver expected the FH_TX interrupt after each section being transferred over the DMA. In order to support this new flow, we enabled all the interrupts. This broke the assumption that we have in the code that the RF-Kill interrupt can't interrupt the firmware load flow. Change the context info flow to enable only the ALIVE interrupt, and re-enable all the other interrupts only after the firmware is alive. Then, we won't see the RF-Kill interrupt until then. Getting the RF-Kill interrupt while loading the firmware made us kill the firmware while it is loading and we ended up dumping garbage instead of the firmware state. Re-enable the ALIVE | RX interrupts from the ISR when we get the ALIVE interrupt to be able to get the RX interrupt that comes immediately afterwards for the ALIVE notification. This is needed for non MSI-X only. Cc: stable@vger.kernel.org Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-06-29iwlwifi: dbg: debug recording stop and restart command removeShahar S Matityahu
The 0xF6 command used to start and stop the recording from 22560 devices was removed. This is causing an assert when the driver tries to alter the recording state. Remove the use of the command.

2019-04-19iwlwifi: unite macros with same meaningShaul Triebitz
TFD_*_SLOTS and IWL_*_QUEUE_SIZE both define the TX queue size (number of TFDs). Get rid of TFD_*_SLOTS and use only IWL_*_QUEUE_SIZE. Signed-off-by: Shaul Triebitz <shaul.triebitz@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

The typical sequence of setting INIT_DONE and then waiting for clock stabilisation is going to need a new workarounds, so first of all refactor it. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2018-09-28iwlwifi: fw: stop and start debugging using host commandSara Sharon
In new devices, access to periphery is forbidden. Send instead host command to start and stop debugging. Memory allocation is written in context info, but in case we need to update it there is a dedicated command. Add definitions, currently unused, of the new command.

Move the restart FW debug code to a function. This avoids code duplication and lays the infra to support the new start and stop host commands in some future devices. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2018-07-26iwlwifi: pcie: support context information for 22560 devicesGolan Ben Ami
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.

2018-04-26iwlwifi: allow different csr flags for different device familiesGolan Ben Ami
Different device families may have different flag values for passing a message to the fw (i.e. SW_RESET). In order to keep the code readable, and avoid conditioning upon the family, store a value for each flag, which indicates the bit that needs to be enabled.

2017-12-20iwlwifi: avoid duplicate sw reset executions in the codeGolan Ben Ami
Most of the sw resets in the code are done by one function, which writes to the relevant CSR. Use the common function to perform the only reset which was done separately, redundant to the common code.
