2020-02-16 | sh_eth: use Gigabit register map for R7S72100 | Sergei Shtylyov | |
The register maps for the Gigabit controllers and the Ether one used on RZ/A1 (AKA R7S72100) are identical except for GECMR which is only present on the true GEther controllers. We no longer use the register map arrays to determine if a given register exists, and have added the GECMR flag to the 'struct sh_eth_cpu_data' in the previous patch, so we're ready to drop the R7S72100 specific register map -- this saves 216 bytes of object code (ARM gcc 4.8.5).

2020-02-16 | sh_eth: add sh_eth_cpu_data::gecmr flag | Sergei Shtylyov | |
Not all Ether controllers having the Gigabit register layout have GECMR -- RZ/A1 (AKA R7S72100) actually has the same layout but no Gigabit speed support and hence no GECMR. In the past, the new register map table was added for this SoC, now I think we should have used the existing Gigabit table with the differences (such as GECMR) covered by the mere flags in the 'struct sh_eth_cpu_data'. Add such flag for GECMR -- and then we can get rid of the R7S72100 specific layout in the next patch...

2020-02-16 | sh_eth: check sh_eth_cpu_data::no_xdfar when dumping registers | Sergei Shtylyov | |
When adding the sh_eth_cpu_data::no_xdfar flag I forgot to add the flag check to __sh_eth_get_regs(), causing the non-existing RDFAR/TDFAR to be considered for dumping on the R-Car gen1/2 SoCs (the register offset check has the final say here)...

2019-12-12 | netdev: pass the stuck queue to the timeout handler | Michael S. Tsirkin | |
This allows incrementing the correct timeout statistic without any mess. Down the road, devices can learn to reset just the specific queue.

2019-11-15 | net: reject PTP periodic output requests with unsupported flags | Jacob Keller | |
Commit 823eb2a3c4c7 ("PTP: add support for one-shot output") introduced a new flag for the PTP periodic output request ioctl. This flag is not currently supported by any driver. Fix all drivers which implement the periodic output request ioctl to explicitly reject any request with flags they do not understand. This ensures that the driver does not accidentally misinterpret the PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future. This is important for forward compatibility: if a new flag is introduced, the driver should reject requests to enable the flag until the driver has actually been modified to support the flag in question.

The sh_eth_close() resets the MAC and then calls phy_stop() so that mdio read access result is incorrect without any error according to kernel trace like below: ifconfig-216 [003] .n.. 109.133124: mdio_access: ee700000.ethernet-ffffffff read phy:0x01 reg:0x00 val:0xffff According to the hardware manual, the RMII mode should be set to 1 before operation the Ethernet MAC. However, the previous code was not set to 1 after the driver issued the soft_reset in sh_eth_dev_exit() so that the mdio read access result seemed incorrect. To fix the issue, this patch adds a condition and set the RMII mode register in sh_eth_dev_exit() for R-Car Gen2 and RZ/A1 SoCs. Note that when I have tried to move the sh_eth_dev_exit() calling after phy_stop() on sh_eth_close(), but it gets worse (kernel panic happened and it seems that a register is accessed while the clock is off).

According to the R-Car Gen3 Hardware Manual Rev 1.50 of Nov 30, 2018, the TX clock internal delay mode isn't supported on R-Car E3 (r8a77990) or D3 (r8a77995). And by extension it is also not supported by RZ/G2E (r9a774c0). This matches all ES versions of the affected SoCs as it is not clear if this problem will be resolved in newer chips. This can be revisited, as necessary. This patch does not error-out if PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_TXID are used on SoCs where TX clock delay mode is not supported as there is a risk of introducing a regression when used in conjunction with older DT blobs present in the field. Rather, a warning is logged in such cases. Based on work by Kazuya Mizuguchi.

2019-04-08 | drivers: Remove explicit invocations of mmiowb() | Will Deacon | |
mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

After the previous patch, all the callers of ndo_select_queue() provide as a 'fallback' argument netdev_pick_tx. The only exceptions are nested calls to ndo_select_queue(), which pass down the 'fallback' available in the current scope - still netdev_pick_tx. We can drop such argument and replace fallback() invocation with netdev_pick_tx(). This avoids an indirect call per xmit packet in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen) with device drivers implementing such ndo. It also clean the code a bit.

2019-02-04 | sh_eth: RX checksum offload support | Sergei Shtylyov | |
Add support for the RX checksum offload. This is enabled by default and may be disabled and re-enabled using 'ethtool': # ethtool -K eth0 rx off # ethtool -K eth0 rx on Some Ether MACs provide a simple checksumming scheme which appears to be completely compatible with CHECKSUM_COMPLETE: sum of all packet data after the L2 header is appended to packet data; this may be trivially read by the driver and used to update the skb accordingly. The same checksumming scheme is implemented in the EtherAVB MACs and now supported by the 'ravb' driver. In terms of performance, throughput is close to gigabit line rate with the RX checksum offload both enabled and disabled. The 'perf' output, however, appears to indicate that significantly less time is spent in do_csum() -- this is as expected.

Commit 62e04b7e0e3c ("sh_eth: rename 'sh_eth_cpu_data::hw_crc'") renamed the field to 'hw_checksum' for the Ether DMAC "intelligent checksum", however some Ether MACs implement a simpler checksumming scheme, so that name now seems misleading. Rename that field to 'csmr' as the "intelligent checksum" is always controlled by the CSMR register.

2019-01-23 | ravb: expand rx descriptor data to accommodate hw checksum | Simon Horman | |
EtherAVB may provide a checksum of packet data appended to packet data. In order to allow this checksum to be received by the host descriptor data needs to be enlarged by 2 bytes to accommodate the checksum. In the case of MTU-sized packets without a VLAN tag the checksum were already accommodated by virtue of the space reserved for the VLAN tag. However, a packet of MTU-size with a VLAN tag consumed all packet data space provided by a descriptor leaving no space for the trailing checksum. This was not detected by the driver which incorrectly used the last two bytes of packet data as the checksum and truncate the packet by two bytes. This resulted all such packets being dropped. A work around is to disable RX checksum offload # ethtool -K eth0 rx off This patch resolves this problem by increasing the size available for packet data in RX descriptors by two bytes. Tested on R-Car E3 (r8a77990) ES1.0 based Ebisu-4D board v2 * Use sizeof(__sum16) directly rather than adding a driver-local #define for the size of the checksum provided by the hw (2 bytes).

2018-09-21 | ravb: Disable Pause Advertisement | Andrew Lunn | |
The previous commit to ravb had the side effect of making the PHY advertise Pause and Asym Pause, which previously did not happen. By default, phydev->supported has both forms of pause enabled, but phydev->advertising does not. The new phy_remove_link_mode() copies phydev->supported to phydev->advertising after removing the requested link mode. These Pause configuration bits appears it stops the PHY from completing Auto-Neg and the link remains down. Be explicit and remove the Pause and Asym Pause modes, so restoring the old behavior.

EtherAVB hardware requires 0 to be written to status register bits in order to clear them, however, care must be taken not to: 1. Clear other bits, by writing zero to them 2. Write one to reserved bits This patch corrects the ravb driver with respect to the second point above. This is done by defining reserved bit masks for the affected registers and, after auditing the code, ensure all sites that may write a one to a reserved bit use are suitably masked.
