2023-01-14ata: libata: cleanup fua support detectionDamien Le Moal
Move the detection of a device FUA support from ata_scsiop_mode_sense()/ata_dev_supports_fua() to device scan time in ata_dev_configure(). The function ata_dev_config_fua() is introduced to detect if a device supports FUA and this support is indicated using the new device flag ATA_DFLAG_FUA. In order to blacklist known buggy devices, the horkage flag ATA_HORKAGE_NO_FUA is introduced. Similarly to other horkage flags, the libata.force= arguments "fua" and "nofua" are also introduced to allow a user to control this horkage flag through the "force" libata module parameter. The ATA_DFLAG_FUA device flag is set only and only if all the following conditions are met: * libata.fua module parameter is set to 1 * The device supports the WRITE DMA FUA EXT command, * The device is not marked with the ATA_HORKAGE_NO_FUA flag, either from the blacklist or set by the user with libata.force=nofua * The device supports NCQ (while this is not mandated by the standards, this restriction is introduced to avoid problems with older non-NCQ devices). Enabling or diabling libata FUA support for all devices can now also be done using the "force=[no]fua" module parameter when libata.fua is set to 1.

2023-01-13PCI/ACPI: Account for _S0W of the target bridge in acpi_pci_bridge_d3()Rafael J. Wysocki
It is questionable to allow a PCI bridge to go into D3 if it has _S0W returning D2 or a shallower power state, so modify acpi_pci_bridge_d3(() to always take the return value of _S0W for the target bridge into account. That is, make it return 'false' if _S0W returns D2 or a shallower power state for the target bridge regardless of its ancestor Root Port properties. Of course, this also causes 'false' to be returned if the Root Port itself is the target and its _S0W returns D2 or a shallower power state. However, still allow bridges without _S0W that are power-manageable via ACPI to enter D3 to retain the current code behavior in that case. This fixes problems where a hotplug notification is missed because a bridge is in D3. That means hot-added devices such as USB4 docks (and the devices they contain) and Thunderbolt 3 devices may not work.

2023-01-13mtd: rawnand: Support for sequential cache readsJaimeLiao
Add support for sequential cache reads for controllers using the generic core helpers for their fast read/write helpers. Sequential reads may reduce the overhead when accessing physically continuous data by loading in cache the next page while the previous page gets sent out on the NAND bus. The ONFI specification provides the following additional commands to handle sequential cached reads: * 0x31 - READ CACHE SEQUENTIAL: Requires the NAND chip to load the next page into cache while keeping the current cache available for host reads. * 0x3F - READ CACHE END: Tells the NAND chip this is the end of the sequential cache read, the current cache shall remain accessible for the host but no more internal cache loading operation is required. On the bus, a multi page read operation is currently handled like this: 00 -- ADDR1 -- 30 -- WAIT_RDY (tR+tRR) -- DATA1_IN 00 -- ADDR2 -- 30 -- WAIT_RDY (tR+tRR) -- DATA2_IN 00 -- ADDR3 -- 30 -- WAIT_RDY (tR+tRR) -- DATA3_IN Sequential cached reads may instead be achieved with: 00 -- ADDR1 -- 30 -- WAIT_RDY (tR) -- \ 31 -- WAIT_RDY (tRCBSY+tRR) -- DATA1_IN \ 31 -- WAIT_RDY (tRCBSY+tRR) -- DATA2_IN \ 3F -- WAIT_RDY (tRCBSY+tRR) -- DATA3_IN Below are the read speed test results with regular reads and sequential cached reads, on NXP i.MX6 VAR-SOM-SOLO in mapping mode with a NAND chip characterized with the following timings: * tR: 20 µs * tRCBSY: 5 µs * tRR: 20 ns and the following geometry: * device size: 2 MiB * eraseblock size: 128 kiB * page size: 2 kiB ============= Normal read @ 33MHz ================= mtd_speedtest: eraseblock read speed is 15633 KiB/s mtd_speedtest: page read speed is 15515 KiB/s mtd_speedtest: 2 page read speed is 15398 KiB/s =================================================== ========= Sequential cache read @ 33MHz =========== mtd_speedtest: eraseblock read speed is 18285 KiB/s mtd_speedtest: page read speed is 15875 KiB/s mtd_speedtest: 2 page read speed is 16253 KiB/s =================================================== We observe an overall speed improvement of about 5% when reading 2 pages, up to 15% when reading an entire block. This is due to the ~14us gain on each additional page read (tR - (tRCBSY + tRR)).

2023-01-13mtd: rawnand: Check the data only read pattern only onceMiquel Raynal
Instead of checking if a pattern is supported each time we need it, let's create a bitfield that only the core would be allowed to fill at startup time. The core and the individual drivers may then use it in order to check what operation they should use. This bitfield is supposed to grow over time.

2023-01-13efi: tpm: Avoid READ_ONCE() for accessing the event logArd Biesheuvel
Nathan reports that recent kernels built with LTO will crash when doing EFI boot using Fedora's GRUB and SHIM. The culprit turns out to be a misaligned load from the TPM event log, which is annotated with READ_ONCE(), and under LTO, this gets translated into a LDAR instruction which does not tolerate misaligned accesses. Interestingly, this does not happen when booting the same kernel straight from the UEFI shell, and so the fact that the event log may appear misaligned in memory may be caused by a bug in GRUB or SHIM. However, using READ_ONCE() to access firmware tables is slightly unusual in any case, and here, we only need to ensure that 'event' is not dereferenced again after it gets unmapped, but this is already taken care of by the implicit barrier() semantics of the early_memunmap() call.

2023-01-13iommu: Remove deferred attach check from __iommu_detach_device()Jason Gunthorpe
At the current moment, __iommu_detach_device() is only called via call chains that are after the device driver is attached - eg via explicit attach APIs called by the device driver. Commit bd421264ed30 ("iommu: Fix deferred domain attachment") has removed deferred domain attachment check from __iommu_attach_device() path, so it should just unconditionally work in the __iommu_detach_device() path. It actually looks like a bug that we were blocking detach on these paths since the attach was unconditional and the caller is going to free the (probably) UNAMANGED domain once this returns. The only place we should be testing for deferred attach is during the initial point the dma device is linked to the group, and then again during the dma api calls.

2023-01-13iommu: Add set_platform_dma_ops iommu opsLu Baolu
When VFIO finishes assigning a device to user space and calls iommu_group_release_dma_owner() to return the device to kernel, the IOMMU core will attach the default domain to the device. Unfortunately, some IOMMU drivers don't support default domain, hence in the end, the core calls .detach_dev instead. This adds set_platform_dma_ops iommu ops to make it clear that what it does is returning control back to the platform DMA ops.

2023-01-13sock: add tracepoint for send recv lengthYunhui Cui
Add 2 tracepoints to monitor the tcp/udp traffic of per process and per cgroup. Regarding monitoring the tcp/udp traffic of each process, there are two existing solutions, the first one is https://www.atoptool.nl/netatop.php. The second is via kprobe/kretprobe. Netatop solution is implemented by registering the hook function at the hook point provided by the netfilter framework. These hook functions may be in the soft interrupt context and cannot directly obtain the pid. Some data structures are added to bind packets and processes. For example, struct taskinfobucket, struct taskinfo ... Every time the process sends and receives packets it needs multiple hashmaps,resulting in low performance and it has the problem fo inaccurate tcp/udp traffic statistics(for example: multiple threads share sockets). We can obtain the information with kretprobe, but as we know, kprobe gets the result by trappig in an exception, which loses performance compared to tracepoint. We compared the performance of tracepoints with the above two methods, and the results are as follows: ab -n 1000000 -c 1000 -r http://127.0.0.1/index.html without trace: Time per request: 39.660 [ms] (mean) Time per request: 0.040 [ms] (mean, across all concurrent requests) netatop: Time per request: 50.717 [ms] (mean) Time per request: 0.051 [ms] (mean, across all concurrent requests) kr: Time per request: 43.168 [ms] (mean) Time per request: 0.043 [ms] (mean, across all concurrent requests) tracepoint: Time per request: 41.004 [ms] (mean) Time per request: 0.041 [ms] (mean, across all concurrent requests It can be seen that tracepoint has better performance.

2023-01-13net: dsa: microchip: ptp: move pdelay_rsp correction field to tail tagChristian Eggers
For PDelay_Resp messages we will likely have a negative value in the correction field. The switch hardware cannot correctly update such values (produces an off by one error in the UDP checksum), so it must be moved to the time stamp field in the tail tag. Format of the correction field is 48 bit ns + 16 bit fractional ns. After updating the correction field, clone is no longer required hence it is freed.

2023-01-13net: dsa: microchip: ptp: add packet transmission timestampingChristian Eggers
This patch adds the routines for transmission of ptp packets. When the ptp pdelay_req packet to be transmitted, it uses the deferred xmit worker to schedule the packets. During irq_setup, interrupt for Sync, Pdelay_req and Pdelay_rsp are enabled. So interrupt is triggered for all three packets. But for p2p1step, we require only time stamp of Pdelay_req packet. Hence to avoid posting of the completion from ISR routine for Sync and Pdelay_resp packets, ts_en flag is introduced. This controls which packets need to processed for timestamp. After the packet is transmitted, ISR is triggered. The time at which packet transmitted is recorded to separate register. This value is reconstructed to absolute time and posted to the user application through socket error queue.

Rx Timestamping is done through 4 additional bytes in tail tag. Whenever the ptp packet is received, the 4 byte hardware time stamped value is added before 1 byte tail tag. Also, bit 7 in tail tag indicates it as PTP frame. This 4 byte value is extracted from the tail tag and reconstructed to absolute time and assigned to skb hwtstamp. If the packet received in PDelay_Resp, then partial ingress timestamp is subtracted from the correction field. Since user space tools expects to be done in hardware.

2023-01-13net: ptp: add helper for one-step P2P clocksChristian Eggers
For P2P delay measurement, the ingress time stamp of the PDelay_Req is required for the correction field of the PDelay_Resp. The application echoes back the correction field of the PDelay_Req when sending the PDelay_Resp. Some hardware (like the ZHAW InES PTP time stamping IP core) subtracts the ingress timestamp autonomously from the correction field, so that the hardware only needs to add the egress timestamp on tx. Other hardware (like the Microchip KSZ9563) reports the ingress time stamp via an interrupt and requires that the software provides this time stamp via tail-tag on tx. In order to avoid introducing a further application interface for this, the driver can simply emulate the behavior of the InES device and subtract the ingress time stamp in software from the correction field. On egress, the correction field can either be kept as it is (and the time stamp field in the tail-tag is set to zero) or move the value from the correction field back to the tail-tag. Changing the correction field requires updating the UDP checksum (if UDP is used as transport).

2023-01-13net: dsa: microchip: ptp: add 4 bytes in tail tag when ptp enabledArun Ramadoss
When the PTP is enabled in hardware bit 6 of PTP_MSG_CONF1 register, the transmit frame needs additional 4 bytes before the tail tag. It is needed for all the transmission packets irrespective of PTP packets or not. The 4-byte timestamp field is 0 for frames other than Pdelay_Resp. For the one-step Pdelay_Resp, the switch needs the receive timestamp of the Pdelay_Req message so that it can put the turnaround time in the correction field. Since PTP has to be enabled for both Transmission and reception timestamping, driver needs to track of the tx and rx setting of the all the user ports in the switch. Two flags hw_tx_en and hw_rx_en are added in ksz_port to track the timestampping setting of each port. When any one of ports has tx or rx timestampping enabled, bit 6 of PTP_MSG_CONF1 is set and it is indicated to tag_ksz.c through tagger bytes. This flag adds 4 additional bytes to the tail tag. When tx and rx timestamping of all the ports are disabled, then 4 bytes are not added.

2023-01-13platform/chrome: cros_ec: Use per-device lockdep keyChen-Yu Tsai
Lockdep reports a bogus possible deadlock on MT8192 Chromebooks due to the following lock sequences: 1. lock(i2c_register_adapter) [1]; lock(&ec_dev->lock) 2. lock(&ec_dev->lock); lock(prepare_lock); The actual dependency chains are much longer. The shortened version looks somewhat like: 1. cros-ec-rpmsg on mtk-scp ec_dev->lock -> prepare_lock 2. In rt5682_i2c_probe() on native I2C bus: prepare_lock -> regmap->lock -> (possibly) i2c_adapter->bus_lock 3. In rt5682_i2c_probe() on native I2C bus: regmap->lock -> i2c_adapter->bus_lock 4. In sbs_probe() on i2c-cros-ec-tunnel I2C bus attached on cros-ec: i2c_adapter->bus_lock -> ec_dev->lock While lockdep is correct that the shared lockdep classes have a circular dependency, it is bogus because a) 2+3 happen on a native I2C bus b) 4 happens on the actual EC on ChromeOS devices c) 1 happens on the SCP coprocessor on MediaTek Chromebooks that just happens to expose a cros-ec interface, but does not have an i2c-cros-ec-tunnel I2C bus In short, the "dependencies" are actually on different devices. Setup a per-device lockdep key for cros_ec devices so lockdep can tell the two instances apart. This helps with getting rid of the bogus lockdep warning. For ChromeOS devices that only have one cros-ec instance this doesn't change anything. Also add a missing mutex_destroy, just to make the teardown complete.
