2019-08-08net: use listified RX for handling GRO_NORMAL skbsEdward Cree1-0/+3
When GRO decides not to coalesce a packet, in napi_frags_finish(), instead of passing it to the stack immediately, place it on a list in the napi struct. Then, at flush time (napi_complete_done(), napi_poll(), or napi_busy_loop()), call netif_receive_skb_list_internal() on the list. We'd like to do that in napi_gro_flush(), but it's not called if !napi->gro_bitmask, so we have to do it in the callers instead. (There are a handful of drivers that call napi_gro_flush() themselves, but it's not clear why, or whether this will affect them.) Because a full 64 packets is an inefficiently large batch, also consume the list whenever it exceeds gro_normal_batch, a new net/core sysctl that defaults to 8.

2019-08-08inet: frags: re-introduce skb coalescing for local deliveryGuillaume Nault1-1/+1
Before commit d4289fcc9b16 ("net: IP6 defrag: use rbtrees for IPv6 defrag"), a netperf UDP_STREAM test[0] using big IPv6 datagrams (thus generating many fragments) and running over an IPsec tunnel, reported more than 6Gbps throughput. After that patch, the same test gets only 9Mbps when receiving on a be2net nic (driver can make a big difference here, for example, ixgbe doesn't seem to be affected). By reusing the IPv4 defragmentation code, IPv6 lost fragment coalescing (IPv4 fragment coalescing was dropped by commit 14fe22e33462 ("Revert "ipv4: use skb coalescing in defragmentation"")). Without fragment coalescing, be2net runs out of Rx ring entries and starts to drop frames (ethtool reports rx_drops_no_frags errors). Since the netperf traffic is only composed of UDP fragments, any lost packet prevents reassembly of the full datagram. Therefore, fragments which have no possibility to ever get reassembled pile up in the reassembly queue, until the memory accounting exeeds the threshold. At that point no fragment is accepted anymore, which effectively discards all netperf traffic. When reassembly timeout expires, some stale fragments are removed from the reassembly queue, so a few packets can be received, reassembled and delivered to the netperf receiver. But the nic still drops frames and soon the reassembly queue gets filled again with stale fragments. These long time frames where no datagram can be received explain why the performance drop is so significant. Re-introducing fragment coalescing is enough to get the initial performances again (6.6Gbps with be2net): driver doesn't drop frames anymore (no more rx_drops_no_frags errors) and the reassembly engine works at full speed. This patch is quite conservative and only coalesces skbs for local IPv4 and IPv6 delivery (in order to avoid changing skb geometry when forwarding). Coalescing could be extended in the future if need be, as more scenarios would probably benefit from it.

device_node_to_regmap() is exactly like syscon_node_to_regmap(), but it does not check that the node is compatible with "syscon", and won't attach the first clock it finds to the regmap. The rationale behind this, is that one device node with a standard compatible string "foo,bar" can be covered by multiple drivers sharing a regmap, or by a single driver doing all the job without a regmap, but these are implementation details which shouldn't reflect on the devicetree.

2019-08-08ALSA: hda: Direct MMIO accessesTakashi Iwai2-34/+30
HD-audio drivers access to the mmio registers indirectly via the corresponding bus->io_ops callbacks. This is because some platform (notably Tegra SoC) requires the word-aligned access. But it's rather a rare case, and other platforms suffer from the penalties by indirect calls unnecessarily. This patch is an attempt to optimize and cleanup for this situation. Now the special aligned access is used only when a new kconfig CONFIG_SND_HDA_ALIGNED_MMIO is set. And the HD-audio core itself provides the aligned MMIO access helpers instead of the driver side. If Kconfig isn't set (as default), the standard helpers like readl() or writel() are used directly. A couple of places in ASoC Intel drivers have the access via io_ops reg_writel(), and they are replaced with the direct writel() calls. And now with this patch, the whole bus->io_ops becomes empty, so it's dropped completely. The bus initialization functions are changed accordingly as well to drop the whole bus->io_ops.

2019-08-08ALSA: hda: Remove page allocation redirectionTakashi Iwai1-5/+1
The HD-audio core allocates and releases pages via driver's specific dma_alloc_pages and dma_free_pages ops defined in bus->io_ops. This was because some platforms require the uncached pages and the handling of page flags had to be done locally in the driver code. Since the recent change in ALSA core memory allocator, we can simply pass SNDRV_DMA_TYPE_DEV_UC for the uncached pages, and the only difference became about this type to be passed to the core allocator. That is, it's good time for cleaning up the mess. This patch changes the allocation code in HD-audio core to call the core allocator directly so that we get rid of dma_alloc_pages and dma_free_pages io_ops. If a driver needs the uncached pages, it has to set bus->dma_type right after the bus initialization. This is merely a code refactoring and shouldn't bring any behavior changes.

2019-08-08ACPI: PM: s2idle: Execute LPS0 _DSM functions with suspended devicesRafael J. Wysocki1-0/+2
According to Section 3.5 of the "Intel Low Power S0 Idle" document [1], Function 5 of the LPS0 _DSM is expected to be invoked when the system configuration matches the criteria for entering the target low-power state of the platform. In particular, this means that all devices should be suspended and in low-power states already when that function is invoked. This is not the case currently, however, because Function 5 of the LPS0 _DSM is invoked by it before the "noirq" phase of device suspend, which means that some devices may not have been put into low-power states yet at that point. That is a consequence of the previous design of the suspend-to-idle flow that allowed the "noirq" phase of device suspend and the "noirq" phase of device resume to be carried out for multiple times while "suspended" (if any spurious wakeup events were detected) and the point of the LPS0 _DSM Function 5 invocation was chosen so as to call it (and LPS0 _DSM Function 6 analogously) once per suspend-resume cycle (regardless of how many times the "noirq" phases of device suspend and resume were carried out while "suspended"). Now that the suspend-to-idle flow has been redesigned to carry out the "noirq" phases of device suspend and resume once in each cycle, the code can be reordered to follow the specification that it is based on more closely. For this purpose, add ->prepare_late and ->restore_early platform callbacks for suspend-to-idle, to be executed, respectively, after the "noirq" phase of suspending devices and before the "noirq" phase of resuming them and make ACPI use them for the invocation of LPS0 _DSM functions as appropriate. While at it, move the LPS0 entry requirements check to be made before invoking Functions 3 and 5 of the LPS0 _DSM (also once per cycle) as follows from the specification [1].

Booting a large arm64 server (HiSi D05) leads to the following shouting at boot time: [ 20.722132] debugfs: File 'irqchip@(____ptrval____)-3' in directory 'domains' already present!

[ 20.774391] debugfs: File 'irqchip@(____ptrval____)-3' in directory 'domains' already present! and many more... Evidently, we expect something a bit more informative than ____ptrval____, and certainly we want all of our domains, not just the first one. For that, turn the %p used to generate the fwnode name into something that won't be repainted (%pa). Given that we've now fixed all users to pass a pointer to a PA, it will actually do the right thing. Acked-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Marc Zyngier <maz@kernel.org>
2019-08-07error-injection: Consolidate override function definitionLeo Yan2-3/+9
The function override_function_with_return() is defined separately for each architecture and every architecture's definition is almost same with each other. E.g. x86 and powerpc both define function in its own asm/error-injection.h header and override_function_with_return() has the same definition, the only difference is that x86 defines an extra function just_return_func() but it is specific for x86 and is only used by x86's override_function_with_return(), so don't need to export this function. This patch consolidates override_function_with_return() definition into asm-generic/error-injection.h header, thus all architectures can use the common definition. As result, the architecture specific headers are removed; the include/linux/error-injection.h header also changes to include asm-generic/error-injection.h header rather than architecture header, furthermore, it includes linux/compiler.h for successful compilation.

Now that the driver core supports dev_groups for individual drivers, expose that pointer to struct usb_device_driver to make it easier for USB drivers to also use it. Yes, users of usb_device_driver are much rare, but there are instances already that use custom sysfs files, so adding this support will make things easier for those drivers. usbip is one example, hubs might be another one.

TC mirred actions (redirect and mirred) can send to egress or ingress of a device. Currently only egress is used for hw offload rules. Modify the intermediate representation for hw offload to include mirred actions that go to ingress. This gives drivers access to such rules and can decide whether or not to offload them.
