Basic support for MT7620 built-in wireless radio was added to OpenWrt in r41441. It has seen some heavy cleaning and refactoring since in order to match the Kernel's code quality standards. Signed-off-by:

Some of the macros used to describe the TX_PWR_CFG_4 register accidentally refer to TX_PWR_CFG_3, probably a copy&paste error. Fix that. Signed-off-by:

If a scan gets aborted BRCMF_SCAN_STATUS_BUSY gets cleared in cfg->scan_status and when we receive an abort event from the firmware the BRCMF_SCAN_STATUS_BUSY check in the cfg80211_escan_handler will trigger resulting in multiple errors getting logged. Check for a status of BRCMF_E_STATUS_ABORT and in this case simply cleanly exit the cfg80211_escan_handler. This also avoids a BRCMF_E_STATUS_ABORT event arriving after a new scan has been started causing the new scan to complete prematurely without any data. Signed-off-by:

Using pr_err for things which are not errors is a bad idea. E.g. it will cause the plymouth bootsplash screen to drop back to the text console so that the user can see the error, which is not what we normally want to happen. Instead add a new brcmf_info macro and use that. Signed-off-by:

So far we were attaching BRCMF_E_PSM_WATCHDOG event listener in brcmf_debug_attach which gets compiled only with CONFIG_BRCMDBG. This event means something went wrong and firmware / hardware usually can't be expected to work (reliably). Such a problem is significant for user experience so I believe we should print an error unconditionally (even with debugging disabled). What can be indeed optional is dumping bus memory as this is clearly part of debugging process. In the future we may also try to extend this listener by trying to recover from the error or at least signal it to the cfg80211. Signed-off-by:

We already have the same check in bcma_of_get_irq which really calls symbols available with CONFIG_OF_IRQ only. It appears this duplicated check was accidentally added in commit c58d900c ("bcma: fix building without OF_IRQ"). The rest of code in bcma_of_fill_device should work fine without CONFIG_OF_IRQ.

Changes in the drivers for RTL8723BE and RTL8821AE require corresponding changes in the firmware. This new firmware has been accepted into the Linux firmware repo. To handle the case where the kernel has been updated before the firmware, the new versions have been given new names. The code will attempt to read the new name, and fall back to the old one if the new one is not available. Signed-off-by:

We observed a SHUTDOWN command timeout during reboot stress test due to a corner case firmware bug. It can lead to either a use-after-free + OOPS (on either the adapter structure, or the 'card' structure) or an abort (where, e.g., the PCI device is "disabled" before we're done dumping the FW). We can avoid this by canceling/flushing the FW dump work: (a) after we've terminated all other work queues (e.g., for processing commands which could time out) (b) after we've disabled all interrupts (which could also queue more work for us) (c) after we've unregistered the netdev and wiphy structures (and implicitly, and debugfs entries which could manually trigger FW dumps) (d) before we've actually disabled the device (e.g., pci_device_disable()) Altogether, this means no card->work will be scheduled if we sync at a point that satisfies the above. This can be done at the beginning of the .cleanup_if() callback. Signed-off-by:Brian Norris <briannorris@chromium.org> Signed-off-by:

Synopsys' ARCompact architecture does not support loading from or storing values to unaligned memory locations. We saw a series of misaligned access exceptions on ARC. To work around this issue, we bulk replaced le16_to_cpu and le32_to_cpu with get_unaligned_le16 and get_unaligned_le32, respectively. We also added le16_unaligned_add_cpu which is similar to le16_add_cpu but works with unaligned values. Signed-off-by:

We shouldn't be printing a kernel pointer as a decimal integer. But we really shouldn't be printing this case at all; we should never get here with NULL drvdata. We've eliminated this unnecessary conditional in several other places, so kill it here too. Similarly, there's no need to check for '!pdev'; we are guaranteed to have a real device here. And finally, use dev_err() instead of pr_err(). This yields (for failed PCIe resets): [ 68.286586] mwifiex_pcie 0000:01:00.0: mwifiex_pcie_reset_notify: adapter structure is not valid instead of: [ 82.932658] mwifiex_pcie: mwifiex_pcie_reset_notify: Card or adapter structure is not valid (-270880688088) Signed-off-by:

Currrently we are disabling this wake irq after receiving it. If this happens before we finish suspend and the pm event check is disabled, the system will continue suspending, and this irq would not work again. We may need to abort system suspend to avoid that. Signed-off-by:

trivial fix to spelling mistake in RT_TRACE message Signed-off-by:

Nils Holland authored
The rtl8187 cards don't seem to receive multicast frames, which, among other things, makes them fail to receive RAs in IPv6 networks. The cause seems to be that the RTL818X_RX_CONF_MULTICAST flag doesn't have the desired effect. Fix the issue by setting RTL818X_RX_CONF_MONITOR instead, which puts the card into monitor mode and resolves the problem so that multicast frames are sucessfully passed to the kernel. The existence of the problem and the effectiveness of the solution has originally been confirmed on an 8187B based card with the USB id of 0bda:8197. Subsequent testing by Larry Finger on an 8187L based card, which follows the second (8187, i.e. "non-b") code path in the driver, has confirmed that the fix does not cause any noticeable regresssions there either.

We use skb_desc->tx_rate_flags from entry as rate[].flags even if skb does not match status. Patch corrects flags and also fixes mcs for legacy rates. rt2800_rate_from_status() is based on Felix's mt76 mt76x2_mac_process_tx_rate() function. Signed-off-by:

If we do not match skb entry, provide tx status via nomatch procedure. Currently in that case we do rt2x00lib_txdone_noinfo(TXDONE_NOINFO), which actually assume that entry->skb was posted without retries and provide rate saved in skb desc as successful. Patch changed that to rate read from TX_STAT_FIFO, however still do not provide correct number of retries. On SoC/PCI devices we keep providing status via standard txdone procedure, no change in those devices, though we should thing about it. Signed-off-by:
