2021-10-17clocksource/drivers/arm_arch_timer: Move system register timer programming ↵Marc Zyngier
over to CVAL In order to cope better with high frequency counters, move the programming of the timers from the countdown timer (TVAL) over to the comparator (CVAL). The programming model is slightly different, as we now need to read the current counter value to have an absolute deadline instead of a relative one. There is a small overhead to this change, which we will address in the following patches.

2021-10-18erofs: get compression algorithms directly on mappingGao Xiang
Currently, z_erofs_map_blocks_iter() returns whether extents are compressed or not, and the decompression frontend gets the specific algorithms then. It works but not quite well in many aspests, for example: - The decompression frontend has to deal with whether extents are compressed or not again and lookup the algorithms if compressed. It's duplicated and too detailed about the on-disk mapping. - A new secondary compression head will be introduced later so that each file can have 2 compression algorithms at most for different type of data. It could increase the complexity of the decompression frontend if still handled in this way; - A new readmore decompression strategy will be introduced to get better performance for much bigger pcluster and lzma, which needs the specific algorithm in advance as well. Let's look up compression algorithms in z_erofs_map_blocks_iter() directly instead.

2021-10-17counter: Add character device interfaceWilliam Breathitt Gray
This patch introduces a character device interface for the Counter subsystem. Device data is exposed through standard character device read operations. Device data is gathered when a Counter event is pushed by the respective Counter device driver. Configuration is handled via ioctl operations on the respective Counter character device node.

2021-10-17counter: Internalize sysfs interface codeWilliam Breathitt Gray
This is a reimplementation of the Generic Counter driver interface. There are no modifications to the Counter subsystem userspace interface, so existing userspace applications should continue to run seamlessly. The purpose of this patch is to internalize the sysfs interface code among the various counter drivers into a shared module. Counter drivers pass and take data natively (i.e. u8, u64, etc.) and the shared counter module handles the translation between the sysfs interface and the device drivers. This guarantees a standard userspace interface for all counter drivers, and helps generalize the Generic Counter driver ABI in order to support the Generic Counter chrdev interface (introduced in a subsequent patch) without significant changes to the existing counter drivers. Note, Counter device registration is the same as before: drivers populate a struct counter_device with components and callbacks, then pass the structure to the devm_counter_register function. However, what's different now is how the Counter subsystem code handles this registration internally. Whereas before callbacks would interact directly with sysfs data, this interaction is now abstracted and instead callbacks interact with native C data types. The counter_comp structure forms the basis for Counter extensions. The counter-sysfs.c file contains the code to parse through the counter_device structure and register the requested components and extensions. Attributes are created and populated based on type, with respective translation functions to handle the mapping between sysfs and the counter driver callbacks. The translation performed for each attribute is straightforward: the attribute type and data is parsed from the counter_attribute structure, the respective counter driver read/write callback is called, and sysfs I/O is handled before or after the driver read/write function is called.

2021-10-16scsi: core: Register sysfs attributes earlierBart Van Assche
A quote from Documentation/driver-api/driver-model/device.rst: "Word of warning: While the kernel allows device_create_file() and device_remove_file() to be called on a device at any time, userspace has strict expectations on when attributes get created. When a new device is registered in the kernel, a uevent is generated to notify userspace (like udev) that a new device is available. If attributes are added after the device is registered, then userspace won't get notified and userspace will not know about the new attributes." Hence register SCSI host sysfs attributes before the SCSI host shost_dev uevent is emitted instead of after that event has been emitted.

One of them uses a shared header file (<soc/arc/timers.h>), which is what is causing the "redefined" warnings, so change the macro name in that driver only. Also change the TIMER_CTRL_NH macro name.

register-DSP model In register DSP models, current parameters of DSP are always reported by messages in isochronous packet. When user operates hardware component such as rotary knob, corresponding message is changed. This commit parses the message and cache current parameters of mixer source function, commonly available for all of register DSP models.

2021-10-15ALSA: firewire-motu: add ioctl command to read cached hardware meterTakashi Sakamoto
This patch adds new ioctl commands for userspace applications to read cached image about hardware meters in register DSP and command DSP models. The content of image differs depending on models. Model-specific parser should be implemented in userspace.

2021-10-15ASoC: audio-graph-card2: add Codec2Codec supportKuninori Morimoto
This patch adds Codec2Codec support to audio-graph-card2. It can use Codec2Codec but very simple case only for now. It doesn't have "SWITCH" control yet, thus it start automatically when it was probed, and can't stop, so far. Thus it needs to be updated around widgets/routing handling, and you need to understand that it is under experimental. Codec has SND_SOC_DAPM_INPUT() (= IN) / SND_SOC_DAPM_OUTPUT(= OUT) widgets in below case. It is assuming 2channel, S32_LE format for now. It needs to be updated, too. It needs "codec2codec" node (= B), needs to have routing (= A), need to indicate CPU side at links (= X). ports@0 is for CPU side (= X), port@1 is Codec side (= Y). It needs to have "rate" (= C) +--+ | |<-- Codec0 <-- IN | |--> Codec1 --> OUT +--+ sound { compatible = "audio-graph-card2"; (A) routing = "OUT" ,"DAI1 Playback", "DAI0 Capture", "IN"; (X) links = <&c2c>; (B) codec2codec { ports { (C) rate = <48000>; (X) c2c: port@0 { c2cf_ep: endpoint { remote-endpoint = <&codec0_ep>; }; }; (Y) port@1 { c2cb_ep: endpoint { remote-endpoint = <&codec1_ep>; }; }; }; }; Codec { ports { port@0 { bitclock-master; frame-master; codec0_ep: endpoint { remote-endpoint = <&c2cf_ep>; }; }; port@1 { codec1_ep: endpoint { remote-endpoint = <&c2cb_ep>; }; }; }; }; Link: https://lore.kernel.org/r/87k0xszlep.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/87y26ylu4a.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>

2021-10-15ASoC: add Audio Graph Card2 driverKuninori Morimoto
We already have audio-graph-card which is Of-graph base of general sound card driver. It is supporting DPCM connection, but was forcibly expanded. Thus, it is very difficult to add new features on it, for example Multi CPU/Codec support, Codec2Codec support, etc. This patch adds more flexible new Audio Graph Card2 driver for it. audio-graph-card and audio-graph-card2 are similar, but don't have full compatibility. Audio Graph Card2 supports very generic connection, but some users want to have its own settings, for example PLL settings, etc. For such case, it has customizing support. In users own driver, it can use Audio Graph Card2 parsing by using audio_graph2_parse_of(), and doing its own customizing. Because Audio Graph Card2 is still under experimental stage, it will indicate such warning when probing, and the DT syntax might be changed.

2021-10-15tcp: md5: Allow MD5SIG_FLAG_IFINDEX with ifindex=0Leonard Crestez
Multiple VRFs are generally meant to be "separate" but right now md5 keys for the default VRF also affect connections inside VRFs if the IP addresses happen to overlap. So far the combination of TCP_MD5SIG_FLAG_IFINDEX with tcpm_ifindex == 0 was an error, accept this to mean "key only applies to default VRF". This is what applications using VRFs for traffic separation want. Signed-off-by: Leonard Crestez <cdleonard@gmail.com> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: David S.

2021-10-15soc: fsl: dpio: add Net DIM integrationIoana Ciornei
Use the generic dynamic interrupt moderation (dim) framework to implement adaptive interrupt coalescing on Rx. With the per-packet interrupt scheme, a high interrupt rate has been noted for moderate traffic flows leading to high CPU utilization. The dpio driver exports new functions to enable/disable adaptive IRQ coalescing on a DPIO object, to query the state or to update Net DIM with a new set of bytes and frames dequeued.

In DPAA2 based SoCs, the IRQ coalesing support per software portal has 2 configurable parameters: - the IRQ timeout period (QBMAN_CINH_SWP_ITPR): how many 256 QBMAN cycles need to pass until a dequeue interrupt is asserted. - the IRQ threshold (QBMAN_CINH_SWP_DQRR_ITR): how many dequeue responses in the DQRR ring would generate an IRQ. Add support for setting up and querying these IRQ coalescing related parameters. Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
