2020-10-08iwlwifi: mvm: ring the doorbell and wait for PNVM load completionLuca Coelho1-0/+1
When we receive a non-zero SKU_ID in the alive notification, we need to ring the doorbell and wait for the FW to send us a PNVM load complete notification before we continue the init phase.

Print out the secure boot status, extended by the PCs of LMACs and the UMAC. This needs to be before dumping, as dumping will corrupt the PC (if the NMI is handled), so move that down. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

2019-09-06iwlwifi: add support for suspend-resume flow for new device generationHaim Dreyfuss1-0/+5
The new device generation has a slightly different suspend resume flow Currently, the way the driver instruct the device to move to D3 is by sending D3_CONFIG_CMD. Instead of using the host command the indication is by writing to the doorbell interrupt. The FW will respond with interrupt to indicate transition completion.

2019-06-01iwlwifi: clear persistence bit according to device familyShahar S Matityahu1-1/+6
The driver attempts to clear persistence bit on any device familiy even though only 9000 and 22000 families require it. Clear the bit only on the relevant device families.

2018-11-11iwlwifi: trans: Clear persistence bit when starting the FWShahar S Matityahu1-0/+7
In D3 suspend flow in 9260 gen2 HW, the NIC receives two PERST signals. The first PERST is expected and indicates the device on coming resume flow. The second PERST causes FW restart FW restart. In order to avoid this issue, the FW set the persistence bit on. Once this bit is set, the FW ignores reset attempts. The problem is when the FW gets assert during D3 and then the persistence bit is set and causes the FW to ignore reset. To handle this issue, the FW opens the preg bit which allows access to the persistence bit, so that the driver clear the persistence bit and reset the NIC. The flow is as follows: the driver checks if the persistence bit is set. If the bit is set, the driver checks if he can clear the bit. If the driver can not clear the bit then there is no point to continue configuring the NIC since it will fail. The fix was added is in start HW flow instead of the resume flow since in general, if the persistence bit is set, the driver can not start the FW. So it is good to check it when we start configuring the NIC. The driver does not need to close the preg bit since the FW close it during the start flow.

2017-06-05iwlwifi: mvm: fix firmware debug restart recordingEmmanuel Grumbach1-0/+1
When we want to stop the recording of the firmware debug and restart it later without reloading the firmware we don't need to resend the configuration that comes with host commands. Sending those commands confused the hardware and led to an NMI 0x66. Change the flow as following: * read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL) * clear those registers * wait for the hardware to complete its write to the buffer * get the data * restore the value of those registers (to restart the recording) For early start (where the configuration is already compiled in the firmware), we don't need to set those registers after the firmware has been loaded, but only when we want to restart the recording without having restarted the firmware.

2017-04-11iwlwifi: pcie: add context information supportSara Sharon1-0/+1
Context information structure is going to be used in a000 devices for firmware self init. The self init includes firmware self loading from DRAM by ROM. This means the TFH relevant firmware loading can be cleaned up. The firmware loading includes the paging memory as well, so op mode can stop initializing the paging and sending the DRAM_BLOCK_CMD. Firmware is doing RFH, TFH and SCD configuration, while driver only fills the required configurations and addresses in the context information structure. The only remaining access to RFH is the write pointer, which is updated upon alive interrupt after FW configured the RFH.
