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.

2018-08-31iwlwifi: remove all occurrences of the FSF address paragraphLuca Coelho1-5/+0
The Free Software Foundation address is superfluous and causes checkpatch to issue a warning when present. Remove all paragraphs with FSF's address to prevent that. Signed-off-by: Luca Coelho <[email protected]>
2017-08-09iwlwifi: fix nmi triggering from hostGolan Ben-Ami1-4/+3
Although nmi was triggered fine till now, it appears that the driver didn't write the exact correct values to the correct addresses for each HW. Fix the nmi triggering by setting the correct addresses and values.

Load FW according to NIC type, taking into account simulation, if exists. This is determined by a prph register. Signed-off-by: Tzipi Peres <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-06-23iwlwifi: use bitfield.h for some registersJohannes Berg1-8/+9
Letting the preprocessor/compiler generate the shift/mask by itself is a win for readability, so use bitfield.h for some registers. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
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.

2017-04-19iwlwifi: mvm: remove unneeded reg write in iwl_mvm_up()Liad Kaufman1-3/+0
Not only that this write is not needed (as FW does this itself), on newer HW this register is write protected so trying to write there will cause problems. Signed-off-by: Liad Kaufman <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

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.

If device family is 8000 then iwl_pcie_load_cpu_sections() won't be called at all (iwl_pcie_load_cpu_sections_8000() is called in that case) so this piece of code never gets called. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

2016-07-06iwlwifi: pcie: Enable MSI mode when using MSI interruptsIdo Yariv1-0/+1
