2022-03-16mt76: fix monitor mode crash with sdio driverDeren Wu1-1/+1
mt7921s driver may receive frames with fragment buffers. If there is a CTS packet received in monitor mode, the payload is 10 bytes only and need 6 bytes header padding after RXD buffer. However, only RXD in the first linear buffer, if we pull buffer size RXD-size+6 bytes with skb_pull(), that would trigger "BUG_ON(skb->len < skb->data_len)" in __skb_pull(). To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to 256 to make sure all MCU operation in linear buffer. [ 52.007562] kernel BUG at include/linux/skbuff.h:2313!

2022-03-13can: mcp251xfd: add RX IRQ coalescing supportMarc Kleine-Budde5-10/+123
This patch adds RX IRQ coalescing support to the driver. The mcp251xfd chip doesn't support proper hardware based coalescing, so this patch tries to implemented it in software. The RX-FIFO offers a "FIFO not empty" interrupt, which is used if no coalescing is active. With activated RX IRQ coalescing the "FIFO not empty" interrupt is disabled in the RX IRQ handler and the "FIFO half full" or "FIFO full interrupt" (depending on RX max coalesced frames IRQ) is used instead. To avoid RX CAN frame starvation a hrtimer is setup with RX coalesce usecs IRQ,on timer expiration the "FIFO not empty" is enabled again. Support for ethtool configuration is added in the next patch.

Simon Horman says: ==================== nfp: preliminary support for NFP-3800 This series is the first step to add support to the NFP driver for the new NFP-3800 device. In this first series the goal is to clean up small issues found while adding support for the new device, prepare an abstraction of the differences between the already supported devices and the new Kestrel device and add the new PCI ID. * Patch 1/11 and 2/11 starts by removing some dead code and incorrect assumptions found while working Kestrel support. Patch 3/11, 4/11 and 5/11 cleans up and prepares for adding the new PCI ID for Kestrel. * Patches 6/11, 7/11, 8/11, 9/11, 10/11 adds, plumb and populates a device information structure to abstract the differences between the existed supported devices (NFP-4000, NFP-5000 and NFP-6000) and the new device (NFP3800). * Finally patch 11/11 adds the new PCI ID for Kestrel. More work is needed to drive the new NFP-3800 device after this first batch of patches the foundation is prepared for the follow up work. Thanks to the work of all those who contributed to this work. ==================== Link: https://lore.kernel.org/r/20220311104306.28357-1-simon.horman@corigine.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-03-12nfp: add support for NFP3800/NFP3803 PCIe devicesDirk van der Merwe6-4/+31
Enable binding the nfp driver to NFP3800 and NFP3803 devices. The PCIE_SRAM offset is different for the NFP3800 device, which also only supports a single explicit group. Changes to Dirk's work: * 48-bit dma addressing is not ready yet. Keep 40-bit dma addressing for NFP3800.

2022-03-12nfp: take chip version into account for ring sizesJakub Kicinski4-10/+16
NFP3800 has slightly different queue controller range bounds. Use the static chip data instead of defines. This commit still assumes unchanged descriptor format. Later datapath changes will allow adjusting for descriptor accounting.

2022-03-12nfp: parametrize QCP offset/size using dev_infoJakub Kicinski6-9/+32
The queue controller (QCP) is accessed based on a device specific offset. The NFP3800 device also supports more queues. Furthermore, the NFP3800 VFs also access the QCP differently to how the NFP6000 VFs accesses it, though still indirectly. Fortunately, we can remove the offset all together for both VF types. This is safe for NFP6000 VFs since the offset was effectively a wrap around and only used for convenience to have it set the same as the NFP6000 PF. Use nfp_dev_info to store queue controller parameters.

2022-03-12nfp: use dev_info for PCIe config space BAR offsetsJakub Kicinski3-12/+12
NFP3800 uses a different PCIe configuration to CPP expansion BAR offsets. We don't need to differentiate between the NFP4000, NFP5000 and NFP6000 since they all use the same offsets.

2022-03-12nfp: introduce dev_info static chip dataJakub Kicinski11-13/+68
In preparation for supporting new chip add a driver data structure which will hold per-chip-version information such as register offsets. Plumb it through to the relevant functions (nfpcore and nfp_net). For now only a very simple member holding chip names is added, following commits will add more.
