| * | ath10k: add basic skeleton to support ahbRaja Mani2016-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qca4019 uses ahb instead of pci where it slightly differs in device enumeration, clock control, reset control, etc. Good thing is that ahb also uses copy engine for the data transaction. So, the most of the stuff implemented in pci.c/ce.c are reusable in ahb case too. Device enumeration in ahb case comes through platform driver/device model. All resource details like irq, memory map, clocks, etc for qca4019 can be fetched from of_node of platform device. Simply flow would look like, device tree => platform device (kernel) => platform driver (ath10k) Device tree entry will have all qca4019 resource details and the same info will be passed to kernel. Kernel will prepare new platform device for that entry and expose DT info to of_node in platform device. Later, ath10k would register platform driver with unique compatible name and then kernels binds to corresponding compatible entry & calls ath10k ahb probe functions. From there onwards, ath10k will take control of it and move forward. New bool flag CONFIG_ATH10K_AHB is added in Kconfig to conditionally enable ahb support in ath10k. On enabling this flag, ath10k_pci.ko will have ahb support. This patch adds only basic skeleton and few macros to support ahb in the context of qca4019.

| * | ath10k: pull reusable code from pci probe and remove for ahbRaja Mani2016-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the code present in ath10k_pci_{probe|remove} are reusable in ahb case too. To avoid code duplication, move reusable code to new functions. Later, those new functions can be called from ahb module's probe and exit functions.

| * | ath10k: make ath10k_pci_read32/write32() ops more genericRaja Mani2016-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ath10k_pci_read32/write32() does work more specific to PCI by ensuring pci wake/sleep for every read and write. There is a plan to use most of stuff available in pci.c (irq stuff, copy engine, etc) for AHB case. Such kind of pci wake/sleep for every read/write is not required in AHB case (qca4019). All those reusable areas in pci.c and ce.c calls ath10k_pci_read32/write32() for low level read and write. In fact, ath10k_pci_read32/write32() should do what it does today for PCI case. But for AHB, it has to do differently. To make ath10k_pci_read32/write32() more generic, new function pointers are added in ar_pci for the function which does operation more close to the bus. Later, corresponding bus specific read and write function will be mapped to that. ath10k_pci_read32/write32() are changed to call directly those function pointers without worrying which bus underlying to it. Also, the function to get number of bank is changed in the same way. Signed-off-by: Raja Mani <rmani@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of static functions present in pci.c file are reusable in ahb (qca4019) case. Remove static word for those reusable functions and have those function prototype declaration in pci.h file. So that, pci.h header file can be included in ahb module and reused.

Warm Reset trigger in continuous beacon stuck for one of the customer for other chip, noticed the MAC was stuck in RTC reset. After analysis noticed DMA did not complete when RTC was put in reset. So, before resetting the MAC need to make sure there are no pending DMA transactions because this reset does not reset all parts of the chip. The 12th and 11th bit of MAC _DMA_CFG register used to do that. 12 cfg_halt_ack 0x0 0 DMA has not yet halted 1 DMA has halted 11 cfg_halt_req 0x0 0 DMA logic operates normally 1 Request DMA logic to stop so software can reset the MAC The Bit [12] of this register indicates when the halt has taken effect or not. the DMA halt IS NOT recoverable; once software sets bit [11] to request a DMA halt, software must wait for bit [12] to be set and reset the MAC. So, the same thing we implemented for ar9580 chip. Signed-off-by: Miaoqing Pan <miaoqing@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| * | wil6210: handle multiple connect/disconnect eventsMaya Erez2016-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current solution wil6210 configures the vring in a worker and holds only one pending CID. This implementation may lead to race conditions between connect and disconnect events of multiple stations or fast connect/disconnect events of the same station. In order to allow the removal of the connect worker and handling of WMI_VRING_CFG_DONE_EVENTID in the connect event, the WMI replies that provide the reply in a given buffer needs to be handled immediately in the WMI event interrupt thread. To prevent deadlocks, WMI replies that requires additional handling are still handled via the events list.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In TX vring allocation, vring_tx->va is allocated before WMI command to configure the vring is sent to the device.

Due to that, in case of disconnect, wil6210_netdev_poll_tx can be called when vring->va is not NULL but vring_tx_data[i]->enabled is already disabled.

| * | wil6210: use extra IEs from probe responseLior David2016-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the start_ap/change_beacon API, when we set up probe response offloading, we only use the IE list from the probe response template and not the IE list from the proberesp_ies argument. As a result, we miss important IEs and it causes problems with some scenarios such as P2P. With this change, we merge the list of IEs from the probe response template and proberesp_ies and send the merged list to the FW for offloading. It is still FW responsibility to filter out irrelevant IEs when sending probe response, based on the actual contents of the probe request. Also in case association response termplate is not provided, we will use the merged list of IEs from probe response in the association response as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the privacy flag calculation in change_beacon checks for RSN IE inside proberesp_ies, but normally it is not found there. It works today because of code inside the function wil_fix_bcon, but wil_fix_bcon is not directly related to change_beacon, and it may be changed or removed in the future and break the calculation. To fix this issue, change the privacy flag calculation to check RSN IE inside the beacon itself. The new check is more reliable and will not be sensitive to changes in wil_fix_bcon.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lawrence reported that git clone could make system crash on a Qualcomm ARM soc based device (DragonBoard, 1G memory without swap) running 64bit Debian. It's turned out the crash is related with rx skb allocation failure. git could consume more than 600MB anonymous memory. And system is in extremely memory shortage case. But driver didn't handle the rx allocation failure case. This patch doesn't submit skb to upper layer if rx skb allocation fails. Instead, it reuse the old skb for rx DMA again. It's more like drop the packets if system is in memory shortage case. With this change, git clone is OOMed instead of system crash.

Tested on MIPS with 560 MHz clock Without CLONED_SKBS flag: TCP Tx 145 Mb/s (iperf result) __copy_user_common consumes 12.9% of CPU (result from perf tool) 0% CPU Idle With CLONED_SKBS flag: TCP Tx 170 Mb/s (iperf result) __copy_user_common consumes 1.8% of CPU (result from perf tool) 12% CPU Idle Signed-off-by: Pawel Kulakowski <pawel.kulakowski@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added a simple interface for platform to perform crash recovery. When firmware crashes, wil driver can notify the platform which can trigger a crash recovery process. During the process the platform can request a ram dump from the wil driver as well as control when firmware recovery will start. This interface allows the platform to implement a more advanced crash recovery, for example to reset dependent subsystems in proper order, or to provide its own notifications during the recovery process.

This change will help STAs out that don’t support SMPS from sticking on 1SS, since they don’t have method to change it back to multiple chains. This change also should not affect power consumption of STAs supporting SMPS, because they are capable to switch the mode to dynamic or static either at the end of frame sequence or by using SMPS action frame.

While reverting the change, pci wake up function is called after accessing pci registers instead of prior to access. The assumption is that chip is woken up before accessing its registers.Though this change does not fix any known issues, this might help to avoid unknown or low power platform specific issues.
