2021-04-19net: enetc: add support for flow controlVladimir Oltean
In the ENETC receive path, a frame received by the MAC is first stored in a 256KB 'FIFO' memory, then transferred to DRAM when enqueuing it to the RX ring. The FIFO is a shared resource for all ENETC ports, but every port keeps track of its own memory utilization, on RX and on TX. There is a setting for RX rings through which they can either operate in 'lossy' mode (where the lack of a free buffer causes an immediate discard of the frame) or in 'lossless' mode (where the lack of a free buffer in the ring makes the frame stay longer in the FIFO). In turn, when the memory utilization of the FIFO exceeds a certain margin, the MAC can be configured to emit PAUSE frames. There is enough FIFO memory to buffer up to 3 MTU-sized frames per RX port while not jeopardizing the other use cases (jumbo frames), and also not consume bytes from the port TX allocations. Also, 3 MTU-sized frames worth of memory is enough to ensure zero loss for 64 byte packets at 1G line rate.

2021-04-19net: enetc: add a mini driver for the Integrated Endpoint Register BlockVladimir Oltean
The NXP ENETC is a 4-port Ethernet controller which 'smells' to operating systems like 4 distinct PCIe PFs with SR-IOV, each PF having its own driver instance, but in fact there are some hardware resources which are shared between all ports, like for example the 256 KB SRAM FIFO between the MACs and the Host Transfer Agent which DMAs frames to DRAM. To hide the stuff that cannot be neatly exposed per port, the hardware designers came up with this idea of having a dedicated register block which is supposed to be populated by the bootloader, and contains everything configuration-related: MAC addresses, FIFO partitioning, etc. When a port is reset using PCIe Function Level Reset, its defaults are transferred from the IERB configuration. Most of the time, the settings made through the IERB are read-only in the port's memory space (if they are even visible), so they cannot be modified at runtime. Linux doesn't have any advanced FIFO partitioning requirements at all, but when reading through the hardware manual, it became clear that, even though there are many good 'recommendations' for default values, many of them were not actually put in practice on LS1028A. So we end up with a default configuration that: (a) does not have enough TX and RX byte credits to support the max MTU of 9600 (which the Linux driver claims already) properly (at full speed) (b) allows the FIFO to be overrun with RX traffic, potentially overwriting internal data structures. The last part sounds a bit catastrophic, but it isn't. Frames are supposed to transit the FIFO for a very short time, but they can actually accumulate there under 2 conditions: (a) there is very severe congestion on DRAM memory, or (b) the RX rings visible to the operating system were configured for lossless operation, and they just ran out of free buffers to copy the frame to. This is what is used to put backpressure onto the MAC with flow control. So since ENETC has not supported flow control thus far, RX FIFO overruns were never seen with Linux. But with the addition of flow control, we should configure some registers to prevent this from happening. What we are trying to protect against are bad actors which continue to send us traffic despite the fact that we have signaled a PAUSE condition. Of course we can't be lossless in that case, but it is best to configure the FIFO to do tail dropping rather than letting it overrun. So in a nutshell, this driver is a fixup for all the IERB default values that should have been but aren't. The IERB configuration needs to be done _before_ the PFs are enabled. So every PF searches for the presence of the "fsl,ls1028a-enetc-ierb" node in the device tree, and if it finds it, it "registers" with the IERB, which means that it requests the IERB to fix up its default values. This is done through -EPROBE_DEFER. The IERB driver is part of the fsl_enetc module, but is technically a platform driver, since the IERB is a good old fashioned MMIO region, as opposed to ENETC ports which pretend to be PCIe devices. The driver was already configuring ENETC_PTXMBAR (FIFO allocation for TX) because due to an omission, TXMBAR is a read/write register in the PF memory space. But the manual is quite clear that the formula for this should depend upon the TX byte credits (TXBCR). In turn, the TX byte credits are only readable/writable through the IERB. So if we want to ensure that the TXBCR register also has a value that is correct and in line with TXMBAR, there is simply no way this can be done from the PF driver, access to the IERB is needed. I could have modified U-Boot to fix up the IERB values, but that is quite undesirable, as old U-Boot versions are likely to be floating around for quite some time from now.

2021-04-19net: enetc: create a common enetc_pf_to_port helperVladimir Oltean
Even though ENETC interfaces are exposed as individual PCIe PFs with their own driver instances, the ENETC is still fundamentally a multi-port Ethernet controller, and some parts of the IP take a port number (as can be seen in the PSFP implementation). Create a common helper that can be used outside of the TSN code for retrieving the ENETC port number based on the PF number. This is only correct for LS1028A, the only Linux-capable instantiation of ENETC thus far. Note that ENETC port 3 is PF 6. The TSN code did not care about this because ENETC port 3 does not support TSN, so the wrong mapping done by enetc_get_port for PF 6 could have never been hit.

2021-04-19drm/i915: Fix modesetting in case of unexpected AUX timeoutsImre Deak
In case AUX failures happen unexpectedly during a modeset, the driver should still complete the modeset. In particular the driver should perform the link training sequence steps even in case of an AUX failure, as this sequence also includes port initialization steps. Not doing that can leave the port/pipe in a broken state and lead for instance to a flip done timeout. Fix this by continuing with link training (in a no-LTTPR mode) if the DPRX DPCD readout failed for some reason at the beginning of link training. After a successful connector detection we already have the DPCD read out and cached, so the failed repeated read for it should not cause a problem. Note that a partial AUX read could in theory partly overwrite the cached DPCD (and return error) but this overwrite should not happen if the returned values are corrupted (due to a timeout or some other IO error). Kudos to Ville to root cause the problem.

2021-04-19IB/ipoib: Improve latency in ipoib/cm connection formationManjunath Patil
Currently IPoIB connected mode queries the device to get the pkey table entry during connection formation. This will increase the time taken to form the connection, especially when limited pkeys are in use. This gets worse when multiple connection attempts are done in parallel. Since ipoib interfaces are locked to a single pkey, use the pkey index that was determined at link up time instead of searching for anything. This improved the latency from 500ms to 1ms on an internal setup.

2021-04-19spi: sync up initial chipselect stateDavid Bauer
When initially probing the SPI slave device, the call for disabling an SPI device without the SPI_CS_HIGH flag is not applied, as the condition for checking whether or not the state to be applied equals the one currently set evaluates to true. This however might not necessarily be the case, as the chipselect might be active. Add a force flag to spi_set_cs which allows to override this early exit condition. Set it to false everywhere except when called from spi_setup to sync up the initial CS state.

2021-04-19spi: stm32-qspi: Add dirmap supportPatrice Chotard
Add stm32_qspi_dirmap_read() and stm32_qspi_dirmap_create() to get dirmap support. Update the exec_op callback which doens't allow anymore memory map access. Memory map access are only available through the dirmap_read callback.

2021-04-19spi: stm32-qspi: Trigger DMA only if more than 4 bytes to transferPatrice Chotard
In order to optimize accesses to spi flashes, trigger a DMA only if more than 4 bytes has to be transferred. DMA transfer preparation's cost becomes negligible above 4 bytes to transfer. Below this threshold, indirect transfer give more throughput. mtd_speedtest shows that page write throughtput increases : - from 779 to 853 KiB/s (~9.5%) with s25fl512s SPI-NOR. - from 5283 to 5666 KiB/s (~7.25%) with Micron SPI-NAND.

2021-04-19spi: stm32-qspi: fix pm_runtime usage_count counterChristophe Kerello
pm_runtime usage_count counter is not well managed. pm_runtime_put_autosuspend callback drops the usage_counter but this one has never been increased. Add pm_runtime_get_sync callback to bump up the usage counter. It is also needed to use pm_runtime_force_suspend and pm_runtime_force_resume APIs to handle properly the clock.
