2021-07-19iwlwifi: mvm: don't change band on bound PHY contextsJohannes Berg1-6/+18
[ Upstream commit 8835a64f74c46baebfc946cd5a2c861b866ebcee ] When we have a P2P Device active, we attempt to only change the PHY context it uses when we get a new remain-on-channel, if the P2P Device is the only user of the PHY context. This is fine if we're switching within a band, but if we're switching bands then the switch implies a removal and re-add of the PHY context, which isn't permitted by the firmware while it's bound to an interface. Fix the code to skip the unbind/release/... cycle only if the band doesn't change (or we have old devices that can switch the band on the fly as well.)

[ Upstream commit 5cc816ef9db1fe03f73e56e9d8f118add9c6efe4 ] The FW has a watchdog of 200ms in the PNVM load flow, so the driver should have a slightly higher timeout.

commit e41eb3e408de27982a5f8f50b2dd8002bed96908 upstream. Sending nulldata packets is important for sw AP link probing and detecting 4-address mode links. The checks that dropped these packets were apparently added to work around an iwlwifi firmware bug with multi-TID aggregation.

2021-05-19iwlwifi: pcie: make cfg vs. trans_cfg more robustJohannes Berg1-7/+28
[ Upstream commit 48a5494d6a4cb5812f0640d9515f1876ffc7a013 ] If we (for example) have a trans_cfg entry in the PCI IDs table, but then don't find a full cfg entry for it in the info table, we fall through to the code that treats the PCI ID table entry as a full cfg entry. This obviously causes crashes later, e.g. when trying to build the firmware name string. Avoid such crashes by using the low bit of the pointer as a tag for trans_cfg entries (automatically using a macro that checks the type when assigning) and then checking that before trying to use the data as a full entry - if it's just a partial entry at that point, fail. Since we're adding some macro magic, also check that the type is in fact either struct iwl_cfg_trans_params or struct iwl_cfg, failing compilation ("initializer element is not constant") if it isn't.

2021-04-14iwlwifi: pcie: properly set LTR workarounds on 22000 devicesJohannes Berg3-32/+37
commit 25628bc08d4526d3673ca7d039eb636aa9006076 upstream. 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.

2021-03-04iwlwifi: mvm: fix the type we use in the PPAG table validity checksLuca Coelho1-6/+13
[ Upstream commit 5a6842455c113920001df83cffa28accceeb0927 ] The value we receive from ACPI is a long long unsigned integer but the values should be treated as signed char. When comparing the received value with ACPI_PPAG_MIN_LB/HB, we were doing an unsigned comparison, so the negative value would actually be treated as a very high number. To solve this issue, assign the value to our table of s8's before making the comparison, so the value is already converted when we do so.

Previously I misinterpreted the situation and thought that this was only going to happen if we had interrupts disabled, and then fixed this (which is good anyway, however), but that didn't always help; looking at it again now I realized that the spin unlock will only reschedule if CONFIG_PREEMPT is used.

2020-11-10iwlwifi: mvm: write queue_sync_state only for syncAvraham Stern1-0/+3
We use mvm->queue_sync_state to wait for synchronous queue sync messages, but if an async one happens inbetween we shouldn't clear mvm->queue_sync_state after sending the async one, that can run concurrently (at least from the CPU POV) with another synchronous queue sync.

2020-11-10iwlwifi: mvm: properly cancel a session protection for P2PEmmanuel Grumbach2-34/+68
We need to feed the configuration id to remove session protection properly. Remember the conf_id when we add the session protection so that we can give it back when we want to remove the session protection. While at it, slightly improve the kernel doc for the conf_id of the notification.

2020-11-10iwlwifi: mvm: use the HOT_SPOT_CMD to cancel an AUX ROCEmmanuel Grumbach1-3/+6
The ROC that runs on the AUX ROC (meaning an ROC on the STA vif), was added with the HOT_SPOT_CMD firmware command and must be cancelled with that same command.

2020-11-02iwlwifi: pcie: limit memory read spin timeJohannes Berg1-9/+27
When we read device memory, we lock a spinlock, write the address we want to read from the device and then spin in a loop reading the data in 32-bit quantities from another register. As the description makes clear, this is rather inefficient, incurring a PCIe bus transaction for every read. In a typical device today, we want to read 786k SMEM if it crashes, leading to 192k register reads. Occasionally, we've seen the whole loop take over 20 seconds and then triggering the soft lockup detector. Clearly, it is unreasonable to spin here for such extended periods of time. To fix this, break the loop down into an outer and an inner loop, and break out of the inner loop if more than half a second elapsed. To avoid too much overhead, check for that only every 128 reads, though there's no particular reason for that number. Then, unlock and relock to obtain NIC access again, reprogram the start address and continue. This will keep (interrupt) latencies on the CPU down to a reasonable time.
