| 2021-02-16 | lan743x: sync only the received area of an rx ring buffer | Sven Van Asbroeck | |
| On cpu architectures w/o dma cache snooping, dma_unmap() is a is a very expensive operation, because its resulting sync needs to invalidate cpu caches. Increase efficiency/performance by syncing only those sections of the lan743x's rx ring buffers that are actually in use.

| 2021-02-16 | lan743x: boost performance on cpu archs w/o dma cache snooping | Sven Van Asbroeck | |
| The buffers in the lan743x driver's receive ring are always 9K, even when the largest packet that can be received (the mtu) is much smaller. This performs particularly badly on cpu archs without dma cache snooping (such as ARM): each received packet results in a 9K dma_{map|unmap} operation, which is very expensive because cpu caches need to be invalidated. Careful measurement of the driver rx path on armv7 reveals that the cpu spends the majority of its time waiting for cache invalidation. Optimize by keeping the rx ring buffer size as close as possible to the mtu. This limits the amount of cache that requires invalidation. This optimization would normally force us to re-allocate all ring buffers when the mtu is changed - a disruptive event, because it can only happen when the network interface is down. Remove the need to re-allocate all ring buffers by adding support for multi-buffer frames. Now any combination of mtu and ring buffer size will work. When the mtu changes from mtu1 to mtu2, consumed buffers of size mtu1 are lazily replaced by newly allocated buffers of size mtu2. These optimizations double the rx performance on armv7. Third parties report 3x rx speedup on armv8.

| 2020-12-16 | lan743x: fix rx_napi_poll/interrupt ping-pong | Sven Van Asbroeck | |
| Even if there is more rx data waiting on the chip, the rx napi poll fn will never run more than once - it will always read a few buffers, then bail out and re-arm interrupts. Which results in ping-pong between napi and interrupt. This defeats the purpose of napi, and is bad for performance. Fix by making the rx napi poll behave identically to other ethernet drivers: 1. initialize rx napi polling with an arbitrary budget (64). 2. in the polling fn, return full weight if rx queue is not depleted, this tells the napi core to "keep polling". 3. update the rx tail ("ring the doorbell") once for every 8 processed rx ring buffers. Thanks to Jakub Kicinski, Eric Dumazet and Andrew Lunn for their expert opinions and suggestions.

| 2020-11-17 | lan743x: replace devicetree phy parse code with library function | Sven Van Asbroeck | |
| The code in this driver which parses the devicetree to determine the phy/fixed link setup, can be replaced by a single library function: of_phy_get_and_connect(). Behaviour is identical, except that the library function will complain when 'phy-connection-type' is omitted, instead of blindly using PHY_INTERFACE_MODE_NA, which would result in an invalid phy configuration. The library function no longer brings out the exact phy_mode, but the driver doesn't need this, because phy_interface_is_rgmii() queries the phydev directly. Remove 'phy_mode' from the private adapter struct. While we're here, log info about the attached phy on connect, this is useful because the phy type and connection method is now fully configurable via the devicetree. Tested on a lan7430 chip with built-in phy. Verified that adding fixed-link/phy-connection-type in the devicetree results in a fixed-link setup. Used ethtool to verify that the devicetree settings are used.

| 2020-11-14 | lan743x: prevent entire kernel HANG on open, for some platforms | Sven Van Asbroeck | |
| On arm imx6, when opening the chip's netdev, the whole Linux kernel intermittently hangs/freezes. This is caused by a bug in the driver code which tests if pcie interrupts are working correctly, using the software interrupt: 1. open: enable the software interrupt 2. open: tell the chip to assert the software interrupt 3. open: wait for flag 4. ISR: acknowledge s/w interrupt, set flag 5. open: notice flag, disable the s/w interrupt, continue Unfortunately the ISR only acknowledges the s/w interrupt, but does not disable it. This will re-trigger the ISR in a tight loop. On some (lucky) platforms, open proceeds to disable the s/w interrupt even while the ISR is 'spinning'. On arm imx6, the spinning ISR does not allow open to proceed, resulting in a hung Linux kernel. Fix minimally by disabling the s/w interrupt in the ISR, which will prevent it from spinning. This won't break anything because the s/w interrupt is used as a one-shot interrupt. Note that this is a minimal fix, overlooking many possible cleanups, e.g.: - lan743x_intr_software_isr() is completely redundant and reads INT_STS twice for no apparent reason - disabling the s/w interrupt in lan743x_intr_test_isr() is now redundant, but harmless - waiting on software_isr_flag can be converted from a sleeping poll loop to wait_event_timeout() Fixes: 23f0703c125b ("lan743x: Add main source files for new lan743x driver") Tested-by: Sven Van Asbroeck <thesven73@gmail.com> # arm imx6 lan7430 Signed-off-by: Sven Van Asbroeck <thesven73@gmail.com> Link: https://lore.kernel.org/r/20201112204741.12375-1-TheSven73@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> | |||

| In the net core, the struct net_device_ops -> ndo_set_rx_mode() callback is called with the dev->addr_list_lock spinlock held. However, this driver's ndo_set_rx_mode callback eventually calls lan743x_dp_write(), which acquires a mutex. Mutex acquisition may sleep, and this is not allowed when holding a spinlock. Fix by removing the dp_lock mutex entirely. Its purpose is to prevent concurrent accesses to the data port. No concurrent accesses are possible, because the dev->addr_list_lock spinlock in the core only lets through one thread at a time.

| Commit 6f197fb63850 ("lan743x: Added fixed link and RGMII support") assumes that chips with an internal PHY will never have a devicetree entry. This is incorrect: even for these chips, a devicetree entry can be useful e.g. to pass the mac address from bootloader to chip: &pcie { status = "okay"; host@0 { reg = <0 0 0 0 0>; #address-cells = <3>; #size-cells = <2>; lan7430: ethernet@0 { /* LAN7430 with internal PHY */ compatible = "microchip,lan743x"; status = "okay"; reg = <0 0 0 0 0>; /* filled in by bootloader */ local-mac-address = [00 00 00 00 00 00]; }; }; }; If a devicetree entry is present, the driver will not attach the chip to its internal phy, and the chip will be non-operational. Fix by tweaking the phy connection algorithm: - first try to connect to a phy specified in the devicetree (could be 'real' phy, or just a 'fixed-link') - if that doesn't succeed, try to connect to an internal phy, even if the chip has a devnode Tested on a LAN7430 with internal PHY. I cannot test a device using fixed-link, as I do not have access to one.

| 2020-09-25 | drivers/net/ethernet: clean up mis-targeted comments | Jesse Brandeburg | |
| As part of the W=1 cleanups for ethernet, a million [*] driver comments had to be cleaned up to get the W=1 compilation to succeed. This change finally makes the drivers/net/ethernet tree compile with W=1 set on the command line. NOTE: The kernel uses kdoc style (see Documentation/process/kernel-doc.rst) when documenting code, not doxygen or other styles. After this patch the x86_64 build has no warnings from W=1, however scripts/kernel-doc says there are 1545 more warnings in source files, that I need to develop a script to fix in a followup patch. The errors fixed here are all kdoc of a few classes, with a few outliers: In file included from drivers/net/ethernet/qlogic/netxen/netxen_nic_hw.c:10: drivers/net/ethernet/qlogic/netxen/netxen_nic.h:1193:18: warning: ‘FW_DUMP_LEVELS’ defined but not used [-Wunused-const-variable=] 1193 | static const u32 FW_DUMP_LEVELS[] = { 0x3, 0x7, 0xf, 0x1f, 0x3f, 0x7f, 0xff }; | ^~~~~~~~~~~~~~ ... repeats 4 times... drivers/net/ethernet/sun/cassini.c:2084:24: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] 2084 | RX_USED_ADD(page, i); drivers/net/ethernet/natsemi/ns83820.c: In function ‘phy_intr’: drivers/net/ethernet/natsemi/ns83820.c:603:6: warning: variable ‘tbisr’ set but not used [-Wunused-but-set-variable] 603 | u32 tbisr, tanar, tanlpar; | ^~~~~ drivers/net/ethernet/natsemi/ns83820.c: In function ‘ns83820_get_link_ksettings’: drivers/net/ethernet/natsemi/ns83820.c:1207:11: warning: variable ‘tanar’ set but not used [-Wunused-but-set-variable] 1207 | u32 cfg, tanar, tbicr; | ^~~~~ drivers/net/ethernet/packetengines/yellowfin.c:1063:18: warning: variable ‘yf_size’ set but not used [-Wunused-but-set-variable] 1063 | int data_size, yf_size; | ^~~~~~~ Normal kdoc fixes: warning: Function parameter or member 'x' not described in 'y' warning: Excess function parameter 'x' description in 'y' warning: Cannot understand <string> on line <NNN> - I thought it was a doc line [*] - ok it wasn't quite a million, but it felt like it.

| 2020-06-01 | lan743x: Added fixed link and RGMII support | Roelof Berg | |
| Microchip lan7431 is frequently connected to a phy. However, it can also be directly connected to a MII remote peer without any phy in between. For supporting such a phyless hardware setup in Linux we utilized phylib, which supports a fixed-link configuration via the device tree. And we added support for defining the connection type R/GMII in the device tree. New behavior: ------------- . The automatic speed and duplex detection of the lan743x silicon between mac and phy is disabled. Instead phylib is used like in other typical Linux drivers. The usage of phylib allows to specify fixed-link parameters in the device tree. . The device tree entry phy-connection-type is supported now with the modes RGMII or (G)MII (default). Development state: ------------------ . Tested with fixed-phy configurations. Not yet tested in normal configurations with phy. Microchip kindly offered testing as soon as the Corona measures allow this. .

| 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.

| 2019-11-11 | Support LAN743x PTP periodic output on any GPIO | John Efstathiades | |
| The LAN743x Ethernet controller provides two independent PTP event channels. Each one can be used to generate a periodic output from the PTP clock. The output can be routed to any one of the available GPIO pins on the device. The PTP clock API can now be used to: - select any LAN743x GPIO pin to function as a periodic output - select either LAN743x PTP event channel to generate the output The LAN7430 has 4 GPIO pins that are multiplexed with its internal PHY LED control signals. A pin assigned to the LED control function will be assigned to the GPIO function if selected for PTP periodic output.

| 2019-09-06 | lan743x: remove redundant assignment to variable rx_process_result | Colin Ian King | |
| The variable rx_process_result is being initialized with a value that is never read and is being re-assigned immediately afterwards. The assignment is redundant, so replace it with the return from function lan743x_rx_process_packet.
