2018-10-25r8169: fix broken Wake-on-LAN from S5 (poweroff)Heiner Kallweit1-2/+7
It was reported that WoL from S5 is broken (WoL from S3 works) and the analysis showed that during system shutdown the network interface was brought down already when the actual kernel shutdown started. Therefore netif_running() returned false and as a consequence the PHY was suspended. Obviously WoL wasn't working then. To fix this the original patch needs to be effectively reverted. A side effect is that when normally bringing down the interface and WoL is enabled the PHY will remain powered on (like it was before the original patch).

2018-10-20r8169: add support for Byte Queue LimitsFlorian Westphal1-5/+13
This patch is basically a resubmit of 1e918876853a ("r8169: add support for Byte Queue Limits") which was reverted later. The problems causing the revert seem to have been fixed in the meantime. Only change to the original patch is that the call to netdev_reset_queue was moved to rtl8169_tx_clear. The Tested-by refers to a system using the RTL8168evl chip version.

2018-10-20r8169: handle all interrupt events in the hard irq handlerHeiner Kallweit1-46/+19
Having a separate "slow event" handler isn't needed because all interrupt events trigger asynchronous activity. And in case of SYSErr we have bigger problems than performance anyway.

2018-10-18r8169: fix NAPI handling under high loadHeiner Kallweit1-5/+3
rtl_rx() and rtl_tx() are called only if the respective bits are set in the interrupt status register. Under high load NAPI may not be able to process all data (work_done == budget) and it will schedule subsequent calls to the poll callback. rtl_ack_events() however resets the bits in the interrupt status register, therefore subsequent calls to rtl8169_poll() won't call rtl_rx() and rtl_tx() - chip interrupts are still disabled. Fix this by calling rtl_rx() and rtl_tx() independent of the bits set in the interrupt status register. Both functions will detect if there's nothing to do for them.

That breaks the MSI-X interrupt. Therefore, we can only fall back to MSI interrupt to fix the issue at that time. However, there is a commit which resolves the drivers getting nothing in PCI BAR=4 after system resumes. It is 04cb3ae895d7 "PCI: Reprogram bridge prefetch registers on resume" by Daniel Drake. After apply the patch, the ethernet adapter works fine before suspend and after resume. So, we can revert the workaround after the commit "PCI: Reprogram bridge prefetch registers on resume" is merged into main tree.

2018-10-11r8169: set RX_MULTI_EN bit in RxConfig for 8168F-family chipsMaciej S. Szmigiero1-2/+2
It has been reported that since commit 05212ba8132b42 ("r8169: set RxConfig after tx/rx is enabled for RTL8169sb/8110sb devices") at least RTL_GIGA_MAC_VER_38 NICs work erratically after a resume from suspend. The problem has been traced to a missing RX_MULTI_EN bit in the RxConfig register. We already set this bit for RTL_GIGA_MAC_VER_35 NICs of the same 8168F chip family so let's do it also for its other siblings: RTL_GIGA_MAC_VER_36 and RTL_GIGA_MAC_VER_38. Curiously, the NIC seems to work fine after a system boot without having this bit set as long as the system isn't suspended and resumed.

2018-10-01r8169: fix network stalls due to missing bit TXCFG_AUTO_FIFOHeiner Kallweit1-12/+8
Some of the chip-specific hw_start functions set bit TXCFG_AUTO_FIFO in register TxConfig. The original patch changed the order of some calls resulting in these changes being overwritten by rtl_set_tx_config_registers() in rtl_hw_start(). This eventually resulted in network stalls especially under high load. Analyzing the chip-specific hw_start functions all chip version from 34, with the exception of version 39, need this bit set.

2018-09-17r8169: Get and enable optional ether_clk clockHans de Goede1-0/+33
On some boards a platform clock is used as clock for the r8169 chip, this commit adds support for getting and enabling this clock (assuming it has an "ether_clk" alias set on it). This is related to commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the firmware") which is a previous attempt to fix this for some x86 boards, but this causes all Cherry Trail SoC using boards to not reach there lowest power states when suspending. This commit (together with an atom-pmc-clk driver commit adding the alias) fixes things properly by making the r8169 get the clock and enable it when it needs it.

2018-09-12r8169: Clear RTL_FLAG_TASK_*_PENDING when clearing RTL_FLAG_TASK_ENABLEDKai-Heng Feng1-3/+6
After system suspend, sometimes the r8169 doesn't work when ethernet cable gets pluggued. This issue happens because rtl_reset_work() doesn't get called from rtl8169_runtime_resume(), after system suspend. In rtl_task(), RTL_FLAG_TASK_* only gets cleared if this condition is met: if (!netif_running(dev) || !test_bit(RTL_FLAG_TASK_ENABLED, tp->wk.flags)) ... If RTL_FLAG_TASK_ENABLED was cleared during system suspend while RTL_FLAG_TASK_RESET_PENDING was set, the next rtl_schedule_task() won't schedule task as the flag is still there. So in addition to clearing RTL_FLAG_TASK_ENABLED, also clears other flags.

2018-09-07r8169: set TxConfig register after TX / RX is enabled, just like RxConfigMaciej S. Szmigiero1-1/+1
Commit 3559d81e76bf ("r8169: simplify rtl_hw_start_8169") changed order of two register writes: 1) Caused RxConfig to be written before TX / RX is enabled, 2) Caused TxConfig to be written before TX / RX is enabled. At least on XIDs 10000000 ("RTL8169sb/8110sb") and 18000000 ("RTL8169sc/8110sc") such writes are ignored by the chip, leaving values in these registers intact. Change 1) was reverted by commit 05212ba8132b42 ("r8169: set RxConfig after tx/rx is enabled for RTL8169sb/8110sb devices"), however change 2) wasn't. In practice, this caused TxConfig's "InterFrameGap time" and "Max DMA Burst Size per Tx DMA Burst" bits to be zero dramatically reducing TX performance (in my tests it dropped from around 500Mbps to around 50Mbps). This patch fixes the issue by moving TxConfig register write a bit later in the code so it happens after TX / RX is already enabled.

2018-08-10r8169: remove version infoHeiner Kallweit1-8/+0
The version number hasn't changed for ages and in general I doubt it provides any benefit. The message in rtl_init_one() may even be misleading because it's printed also if something fails in probe. Therefore let's remove the version information. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-07-24r8169: restore previous behavior to accept BIOS WoL settingsHeiner Kallweit1-2/+1
Commit 7edf6d314cd0 tried to resolve an inconsistency (BIOS WoL settings are accepted, but device isn't wakeup-enabled) resulting from a previous broken-BIOS workaround by making disabled WoL the default. This however had some side effects, most likely due to a broken BIOS some systems don't properly resume from suspend when the MagicPacket WoL bit isn't set in the chip, see https://bugzilla.kernel.org/show_bug.cgi?id=200195 Therefore restore the WoL behavior from 4.16.

2018-07-18r8169: power down chip in probeHeiner Kallweit1-3/+4
The removed code would be called in two situations: 1. interface is brought up never or >10s after driver load 2. after close() Case 1 we can handle cleaner by ensuring chip is powered down when leaving probe(). open() callback will power up the chip. In case 2 we call rtl_pll_power_down() twice currently, from the close() callback and 10s later when entering runtime-suspend. This is avoided by this patch.
