2020-01-06remove ioremap_nocache and devm_ioremap_nocacheChristoph Hellwig1-4/+4
ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Arnd Bergmann <arnd@arndb.de>
2019-04-26nfp: implement PCI driver shutdown callbackDirk van der Merwe1-2/+9
Device may be shutdown without the hardware being reinitialized, in which case we want to ensure we cleanup properly. This is especially important for kexec with traffic flowing. The shutdown procedures resembles the remove procedures, so we can reuse those common tasks.

2018-05-23nfp: assign vNIC id as phys_port_name of vNICs which are not portsJakub Kicinski1-1/+1
When NFP is modelled as a switch we assign phys_port_name to respective port(representor )s: vNIC0 - | - PF port (pf%d) MAC/PHY (p%d[s%d]) - |E== In most cases there is only one vNIC for communication with the switch. If there is more than one we need to be able to identify them. Use %d as phys_port_name of the vNICs. We don't have to pass ID to nfp_net_debugfs_vnic_add() separately any more.

2018-01-19nfp: read ME frequency from vNIC ctrl memoryJakub Kicinski1-6/+0
PCIe island clock frequency is used when converting coalescing parameters from usecs to NFP timestamps. Most chips don't run at 1200MHz, allow FW to provide us with the real frequency.

2017-06-07nfp: advertise support for NFD ABI 0.5Jakub Kicinski1-1/+1
NFD ABI 0.5 is equivalent to NFD ABI 3.0 but requires that the driver checks the APP id symbol and makes sure it can support given app. Most advanced apps will likely require control vNIC (ability to exchange control messages between the driver and app FW). Detailed app version checking and capability exchange is left to app-specific code. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-07nfp: allow allocation and initialization of netdev-less vNICsJakub Kicinski1-1/+1

2017-05-22nfp: rename netdev/port to vNICJakub Kicinski1-2/+2
vNIC is a PCIe-side abstraction NFP firmwares supported by this driver use. It was initially meant to represent a device port and therefore a netdev but today should be thought of as a way of grouping descriptor rings and associated state. Advanced apps will have vNICs without netdevs and ports without a vNIC (using representors instead). Make sure code refers to vNICs as vNICs and not ports or netdevs. No functional changes.

2017-05-22nfp: make nfp_net alloc/init/cleanup/free not depend on netdevsJakub Kicinski1-5/+5
struct nfp_net represents a vNIC, we will be moving away from the requirement for every vNIC to have a netdev associated with it. Remove "netdev" from some function names and prefer passing struct nfp_net pointer as argument instead of struct net_device *.

2017-02-10nfp: rename the driver and add new main fileJakub Kicinski1-34/+4
Support for the PF driver is about to be added and will share much of the code. When the VF driver was added we planned to maintain the PF driver as a separate module but have decided that for our simple use case just maintaining a single module is more reasonable. Rename the driver to just "nfp" and update the Kconfig. While at it remove latent references to NFP3200. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.
