2017-06-05iwlwifi: tt: move ucode_loaded check under mutexJohannes Berg1-3/+5
The ucode_loaded check should be under the mutex, since it can otherwise change state after we looked at it and before we got the mutex. Fix that.

During d0i3 flow we flush all the queue except from the command queue. Currently, in this flow the command queue is hard coded to 9. In DQA the command queue number has changed from 9 to 0. Fix that.

2017-06-05iwlwifi: mvm: rs: start using LQ command colorGregory Greenman6-36/+47
Up until now, the driver was comparing the rate reported by the FW and the rate of the latest LQ command to avoid processing data belonging to the old LQ command. Recently, FW changed the meaning of the initial rate field in tx response and it holds the actual rate (which is not necessarily the initial rate of LQ's rate table). Use instead LQ cmd color to be able to filter out tx responses/BA notifications which where sent during earlier LQ commands' time frame. This fixes some throughput degradation in noisy environments.

2017-06-01brcmfmac: fix alignment configuration on host using 64-bit DMAArend Van Spriel1-1/+1
For SDIO the alignment requirement for transfers from device to host is configured in firmware. This configuration is limited to minimum of 4-byte alignment. However, this is not correct for platforms using 64-bit DMA when the minimum alignment should be 8 bytes. This issue appeared when the ALIGNMENT definition was set according the DMA configuration. The configuration in firmware was not using that macro defintion, but a hardcoded value of 4. Hence the driver reported alignment failures for data coming from the device and causing transfers to fail.

2017-05-31ath10k: go back to using dma_alloc_coherent() for firmware scratch memoryAdrian Chadd1-25/+10
This reverts commit b057886524be ("ath10k: do not use coherent memory for allocated device memory chunks") in 2015 which converted this allocation from dma_map_coherent() to kzalloc() / dma_map_single(). The current problem manifests when using later model NICs with larger (>700KiB) scratch spaces in memory. Although the kzalloc call succeeds, the software IOMMU TLB code (via dma_map_single()) panics because it can't find 700KiB of linear physmem bounce buffers for DMA. Now, this is a bit of a silly failure mode for the dma map API, but it's what we currently have to play with. In these cases, doing kzalloc() works fine, but the dma_map_single() call fails. After chatting with Linus briefly about this, it indeed should be using dma_alloc_coherent() for doing larger device memory allocation that requires some kind of physical address mapping. You're not supposed to be using kzalloc and dma_map_* calls for large memory regions, and I'm guessing not for long-held mappings either. Typically dma mappings should be temporary for DMA, not long held like these. Now, since hopefully the major annoying underlying problem has also been addressed (ie, ath10k is no longer tears down all of these allocations and reallocates them every time the vdevs are brought down) fragmentation should stop being such a touchy issue. If it is though, using dma_alloc_coherent() use gets us access to the CMB APIs too relatively easily and ideally we would be allocating memory early in boot for exactly these reasons.
