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 'setup_hw()' (hfcpci.c) GFP_KERNEL can be used because it is called from the probe function and no lock is taken. The call chain is: hfc_probe() --> setup_card() --> setup_hw() When memory is allocated in 'inittiger()' (netjet.c) GFP_ATOMIC must be used because a spin_lock is taken by the caller (i.e. 'nj_init_card()') This is also consistent with the other allocations done in the function. @@ @@ - 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:

Add tdc to existing kselftest infrastructure so that it can be run with existing kselftests. TDC now generates objects in objdir/kselftest without cluttering main objdir, leaves source directory clean, and installs correctly in kselftest_install, properly adding itself to run_kselftest.sh script. Add tc-testing as a target of selftests/Makefile. Create tdc.sh to run tdc.py targets with correct arguments. To support single target from selftest/Makefile, combine tc-testing/bpf/Makefile and tc-testing/Makefile. Move action.c up a directory to tc-testing/. Tested with: make O=/tmp/{objdir} TARGETS="tc-testing" kselftest cd /tmp/{objdir} cd kselftest cd tc-testing ./tdc.sh make -C tools/testing/selftests/ TARGETS=tc-testing run_tests make TARGETS="tc-testing" kselftest cd tools/testing/selftests ./kselftest_install.sh /tmp/exampledir My VM doesn't run all the kselftests so I commented out all except my target and net/pmtu.sh then: cd /tmp/exampledir && ./run_kselftest.sh Co-developed-by:Davide Caratti <dcaratti@redhat.com> Signed-off-by:

This patch enables ipv6 support for TCP LSO and UDP GSO. The code itself (aq_nic_map_skb) was ready for this after udp gso feature, but corresponding NETIF_F_TSO6 wasn't enabled. We now have tested both tcp and udp v6 GSO, and enabling them safely. Signed-off-by:

Mark Starovoytov authored
This patch adds u64_stats_update_* usage to protect access to 64-bit stats, where necessary. This is necessary for per-ring stats, because they are updated by the driver directly, so there is a possibility for a partial read. Other stats require no additional protection, e.g.: * all MACSec stats are fetched directly from HW (under semaphore); * nic/ndev stats (aq_stats_s) are fetched directly from FW (under mutex).

Vladimir Oltean says: ==================== Extend testptp with PTP perout waveform Demonstrate the usage of the newly introduced flags in the PTP_PEROUT_REQUEST2 ioctl: https://www.spinics.net/lists/netdev/msg669346.html ==================== Signed-off-by:

Vladimir Oltean authored
Extend the example program for PTP ancillary functionality with the ability to configure not only the periodic output's period (frequency), but also the phase and duty cycle (pulse width) which were newly introduced. The ioctl level also needs to be updated to the new PTP_PEROUT_REQUEST2, since the original PTP_PEROUT_REQUEST doesn't support this functionality. For an in-tree testing program, not having explicit backwards compatibility is fine, as it should always be tested with the current kernel headers and sources. Tested with an oscilloscope on the felix switch PHC: echo '2 0' > /sys/class/ptp/ptp1/pins/switch_1588_dat0 ./testptp -d /dev/ptp1 -p 1000000000 -w 100000000 -H 1000 -i 0 Signed-off-by:

Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. This driver makes use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device(), pci_set_power_state() and pci_set_master() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use to_pci_dev() and dev_get_drvdata() to get "struct pci_dev*" variable and drv data. Compile-tested only. Signed-off-by:

Alexander Lobakin says: ==================== qed, qede: add support for new operating modes This series covers the support for the following: - new port modes; - loopback modes, previously missing; - new speed/link modes; - several FEC modes; - multi-rate transceivers; and also cleans up and optimizes several related parts of code. v3 (from [2]): - dropped custom link mode declaration; qed, qede and qedf switched to Ethtool link modes and definitions (#0001, #0002, per Andrew Lunn's suggestion); - exchange more .text size to .initconst and .ro_after_init in qede (#0003). v2 (from [1]): - added a patch (#0010) that drops discussed dead struct member; - addressed checkpatch complaints on #0014 (former #0013); - rebased on top of latest net-next; - no other changes.

Currently qed driver does not take into consideration transceiver's capabilities when generating link partner's speed advertisement. This leads to e.g. incorrect ethtool link info on 10GbaseT modules. Use transceiver info not only for advertisement and support arrays, but also for link partner's abilities to fix it. Misc: fix a couple of comments nearby. Signed-off-by:

Currently qed driver already ran out of 32 bits to store link modes, and this doesn't allow to add and support more speeds. Convert custom link mode to generic Ethtool bitmap and definitions (convenient Phylink shorthands are used for elegance and readability). This allowed us to drop all conversions/mappings between the driver and Ethtool. This involves changes in qede and qedf as well, as they used definitions from shared "qed_if.h". Suggested-by:

Merge tag 'wireless-drivers-next-2020-07-20' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for v5.9 First set of patches for v5.9. This comes later than usual as I was offline for two weeks. The biggest change here is moving Microchip wilc1000 driver from staging. There was an immutable topic branch with one commit moving the whole driver and the topic branch was pulled both to staging-next and wireless-drivers-next. At the moment the only reported conflict is in MAINTAINERS file, so I'm hoping the move should go smoothly. Other notable changes are ath11k getting 6 GHz band support and rtw88 supporting RTL8821CE. And there's also the usual fixes, API changes and cleanups all over. Major changes: wilc1000 * move from drivers/staging to drivers/net/wireless/microchip ath11k * add 6G band support * add spectral scan support iwlwifi * make FW reconfiguration quieter by not using warn level rtw88 * add support for RTL8821CE ==================== Signed-off-by:
