2019-05-01net: ll_temac: Enable DMA when ready, not beforeEsben Haabendal1-5/+10
As soon as TAILDESCR_PTR is written, DMA transfers might start. Let's ensure we are ready to receive DMA IRQ's before doing that. Signed-off-by: Esben Haabendal <esben@geanix.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-05-01net: ll_temac: Allow configuration of IRQ coalescingEsben Haabendal2-12/+32
This allows custom setup of IRQ coalescing for platforms using legacy platform_device. The irq timeout and count parameters can be used for tuning cpu load vs. latency. I have maintained the 0x00000400 bit in TX_CHNL_CTRL. It is specified as unused in the documentation I have available. It does not make any difference in the hardware I have available, so it is left in to not risk breaking other platforms where it might be used.

2019-05-01net: ll_temac: Support indirect_mutex share within TEMAC IPEsben Haabendal3-20/+37
Indirect register access goes through a DCR bus bridge, which allows only one outstanding transaction. And to make matters worse, each TEMAC IP block contains two Ethernet interfaces, and although they seem to have separate registers for indirect access, they actually share the registers. Or to be more specific, MSW, LSW and CTL registers are physically shared between Ethernet interfaces in same TEMAC IP, with RDY register being (almost) specificic to the Ethernet interface. The 0x10000 bit in RDY reflects combined bus ready state though. So we need to take care to synchronize not only within a single device, but also between devices in same TEMAC IP. This commit allows to do that with legacy platform devices. For OF devices, the xlnx,compound parent of the temac node should be used to find siblings, and setup a shared indirect_mutex between them. I will leave this work to somebody else, as I don't have hardware to test that. No regression is introduced by that, as before this commit using two Ethernet interfaces in same TEMAC block is simply broken.

2019-05-01net: ll_temac: Fix support for little-endian platformsEsben Haabendal1-39/+50
Both TEMAC and SDMA is big-endian, so make sure that all values in SDMA buffer descriptors (cmdac_bd) are handled as big-endian, independent of the host endianness. With all currently supported platforms being big-endian, this change does not make a change for any of them. Note, when using app3 and app4 for piggybacking skb pointers there is no need to care about endianness, as neither TEMAC nor SDMA access app3 and app4 in TX buffer descriptors.

2019-05-01net: ll_temac: Add support for non-native register endiannessEsben Haabendal2-22/+77
Replace the powerpc specific MMIO register access functions with the generic big-endian mmio access functions, and add support for little-endian access depending on configuration. Big-endian access is maintained as the default, but little-endian can be configured in device-tree binding or in platform data. The temac_ior()/temac_iow() functions are replaced with macro wrappers to avoid modifying existing code more than necessary. Signed-off-by: Esben Haabendal <esben@geanix.com> Signed-off-by: David S.

2019-05-01net: ll_temac: Fix support for 64-bit platformsEsben Haabendal2-4/+32
The use of buffer descriptor APP4 field (32-bit) for storing skb pointer obviously does not work on 64-bit platforms. As APP3 is also unused, we can use that to store the other half of 64-bit pointer values. Contrary to what is hinted at in commit message of commit 15bfe05c8d63 ("net: ethernet: xilinx: Mark XILINX_LL_TEMAC broken on 64-bit") there are no other pointers stored in cdmac_bd.

2019-05-01net: ll_temac: Fix and simplify error handling by using devres functionsEsben Haabendal3-42/+22
As a side effect, a few error cases are fixed. If of_iomap() of sdma_regs failed, no error code was returned. Fixed to return -ENOMEM similar to of_iomap() fail of regs. If sysfs_create_group() or register_netdev() failed, lp->phy_node was not released. Finally, the order in remove function is corrected to be reverse order of what is done in probe, i.e. calling temac_mdio_teardown() last, so we unregister the netdev that most likely is using the mdio_bus first.

This is done through a new `bpftool btf dump` sub-command, from Andrii. 3) Enable BPF-based flow dissector for skb-less eth_get_headlen() calls which was currently not supported since skb was used to lookup netns, from Stanislav. 4) Add an opt-in interface for tracepoints to expose a writable context for attached BPF programs, used here for NBD sockets, from Matt. 5) BPF xadd related arm64 JIT fixes and scalability improvements, from Daniel. 6) Change the skb->protocol for bpf_skb_adjust_room() helper in order to support tunnels such as sit.
