2020-12-14bnxt_en: Enable batch mode when using HWRM_NVM_MODIFY to flash packages.Michael Chan
The current scheme allocates a DMA buffer as big as the requested firmware package file and DMAs the contents to firmware in one operation. The buffer size can be several hundred kilo bytes and the driver may not be able to allocate the memory. This will cause firmware upgrade to fail. Improve the scheme by using smaller DMA blocks and calling firmware to DMA each block in a batch mode. Older firmware can cause excessive NVRAM erases if the block size is too small so we try to allocate a 256K buffer to begin with and size it down successively if we cannot allocate the memory.

In bnxt_flash_package_from_fw_obj(), if firmware returns the NO_SPACE error, call __bnxt_flash_nvram() to create the UPDATE directory and then loop back and retry one more time.

On NICs with a smaller NVRAM, FW installation may fail after multiple updates due to fragmentation. The driver can retry when FW returns a special error code.

2020-12-14can: m_can: use struct m_can_classdev as drvdataMarc Kleine-Budde
The m_can driver's suspend and resume functions (m_can_class_suspend() and m_can_class_resume()) make use of dev_get_drvdata() and assume that the drvdata is a pointer to the struct net_device. With upcoming conversion of the tcan4x5x driver to pm_runtime this assumption is no longer valid. As the suspend and resume functions actually need a struct m_can_classdev pointer, change the m_can_platform and the m_can_pci driver to hold a pointer to struct m_can_classdev instead, as the tcan4x5x driver already does.

2020-12-14xen/xenbus: Allow watches discard events before queueingSeongJae Park
If handling logics of watch events are slower than the events enqueue logic and the events can be created from the guests, the guests could trigger memory pressure by intensively inducing the events, because it will create a huge number of pending events that exhausting the memory. Fortunately, some watch events could be ignored, depending on its handler callback. For example, if the callback has interest in only one single path, the watch wouldn't want multiple pending events. Or, some watches could ignore events to same path. To let such watches to volutarily help avoiding the memory pressure situation, this commit introduces new watch callback, 'will_handle'. If it is not NULL, it will be called for each new event just before enqueuing it. Then, if the callback returns false, the event will be discarded. No watch is using the callback for now, though.

Now that all the needed pieces are in place implement suspend support QCA6390 PCI devices. All other devices will return -EOPNOTSUPP during suspend. The suspend is implemented by switching the firmware to WoW mode during suspend, so the firmware will be running on low power mode while host is in suspend. At the moment we are not able to shutdown and fully power off the device due to bugs in MHI subsystem, so WoW mode is a workaround for the time being. During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to suspend state. During resume, driver resumes MHI firstly, then enables CE irq and dp IRQ, and sends WoW wakeup command to firmware.

2020-12-12ath11k: Fix incorrect tlvs in scan start commandPradeep Kumar Chitrapu
Currently 6G specific tlvs have duplicate entries which is causing scan failures. Fix this by removing the duplicate entries of the same tlv. This also fixes out-of-bound memory writes caused due to adding tlvs when num_hint_bssid and num_hint_s_ssid are ZEROs.

2020-12-12ath10k: add atomic protection for device recoveryWen Gong
When it has more than one restart_work queued meanwhile, the 2nd restart_work is very easy to break the 1st restart work and lead recovery fail. Add a flag to allow only one restart work running untill device successfully recovered. It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this flag again, because it is clear in ath10k_core_start. The function ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do many things and drv_start(call to ath10k_core_start) is 1st thing, when drv_start complete, it does not mean restart complete. So it add new flag and clear it in ath10k_reconfig_complete, because it is the last thing called from drv_reconfig_complete of function ieee80211_reconfig, after it, the restart process finished.
