2021-04-20thermal/drivers/intel: Introduce tcc cooling driverZhang Rui3-0/+141
On Intel processors, the core frequency can be reduced below OS request, when the current temperature reaches the TCC (Thermal Control Circuit) activation temperature. The default TCC activation temperature is specified by MSR_IA32_TEMPERATURE_TARGET. However, it can be adjusted by specifying an offset in degrees C, using the TCC Offset bits in the same MSR register. This patch introduces a cooling devices driver that utilizes the TCC Offset feature. The bigger the current cooling state is, the lower the effective TCC activation temperature is, so that the processors can be throttled earlier before system critical overheats. Note that, on different platforms, the behavior might be different on how fast the setting takes effect, and how much the CPU frequency is reduced. This patch has been tested on a KabyLake mobile platform from me, and also on a CometLake platform from Doug.

2021-04-19net/mlx5: DR, Add support for isolate_vl_tc QPYevgeny Kliteynik3-0/+11
When using SW steering, rule insertion rate depends on the RDMA RC QP performance used for writing to the ICM. During stress this QP is competing on the HW resources with all the other QPs that are used to send data. To protect SW steering QP's performance in such cases, we set this QP to use isolated VL. The VL number is reserved by FW and is not exposed to the driver. Support for this QP on isolated VL exists only when both force-loopback and isolate_vl_tc capabilities are set.

2021-04-19net: enetc: add support for flow controlVladimir Oltean3-2/+85
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 Oltean5-1/+221
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 Oltean2-10/+22
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 Deak1-1/+2
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.

Instead of manually messing with parent driver module reference counting rely on export symbol mechanism to ensure that proper probe/remove chain is performed.

Convert indirect probe call to its direct equivalent to create a symbol link between RDMA and netdev modules. This will give us an ability to remove custom module reference counting that doesn't belong to the driver.
