2020-08-27rtw88: switch from 'pci_' to 'dma_' APIChristophe JAILLET
The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'rtw_pci_init_tx_ring()' and 'rtw_pci_init_rx_ring()' GFP_KERNEL can be used because both functions are called from a probe function and no spinlock is taken. The call chain is: rtw_pci_probe --> rtw_pci_setup_resource --> rtw_pci_init --> rtw_pci_init_trx_ring --> rtw_pci_init_tx_ring --> rtw_pci_init_rx_ring @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20200820150643.148219-1-christophe.jaillet@wanadoo.fr

2020-08-27mwifiex: don't call del_timer_sync() on uninitialized timerTetsuo Handa
syzbot is reporting that del_timer_sync() is called from mwifiex_usb_cleanup_tx_aggr() from mwifiex_unregister_dev() without checking timer_setup() from mwifiex_usb_tx_init() was called [1]. Ganapathi Bhat proposed a possibly cleaner fix, but it seems that that fix was forgotten [2]. "grep -FrB1 'del_timer' drivers/ | grep -FA1 '.function)'" says that currently there are 28 locations which call del_timer[_sync]() only if that timer's function field was initialized (because timer_setup() sets that timer's function field). Therefore, let's use same approach here.

2020-08-27mwifiex: Clean up some err and dbg messagesChristophe JAILLET
The error message if 'pci_set_consistent_dma_mask()' fails is misleading. The function call uses 32 bits, but the error message reports 64. Moreover, according to the comment above 'dma_set_mask_and_coherent()' definition, such an error can never happen. So, simplify code, axe the misleading message and use 'dma_set_mask_and_coherent()' instead of 'dma_set_mask()' + 'dma_set_coherent_mask()' While at it, make some clean-up: - add # when reporting allocated length to be consistent between functions - s/consistent/coherent/ - s/unsigned int/u32/ to be consistent between functions - align some code Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20200819071853.113185-1-christophe.jaillet@wanadoo.fr

2020-08-18ath10k: Register shutdown handlerRakesh Pillai
As a part of device shutdown the smmu driver will be stopped and henceforth any IOVA address translation will not be done. The wlan driver, being one of the smmu driver consumer, should stop all the dma related activity as a part of shutdown, and thereby ensuring that no dma activity is done once the smmu driver shuts down. During the device shutdown, the smmu calls shutdown for all its consumers in order to indicate them to stop all their dma activities. Register the shutdown handler to stop the wlan driver and avoid any dma operations.
