2024-11-12hisi_acc_vfio_pci: create subfunction for data readingLongfang Liu
This patch generates the code for the operation of reading data from the device into a sub-function. Then, it can be called during the device status data saving phase of the live migration process and the device status data reading function in debugfs. Thereby reducing the redundant code of the driver.

2024-11-12hisi_acc_vfio_pci: extract public functions for container_ofLongfang Liu
In the current driver, vdev is obtained from struct hisi_acc_vf_core_device through the container_of function. This method is used in many places in the driver. In order to reduce this repetitive operation, It was extracted into a public function.

2024-10-30vfio/qat: fix overflow check in qat_vf_resume_write()Giovanni Cabiddu
The unsigned variable `size_t len` is cast to the signed type `loff_t` when passed to the function check_add_overflow(). This function considers the type of the destination, which is of type loff_t (signed), potentially leading to an overflow. This issue is similar to the one described in the link below. Remove the cast. Note that even if check_add_overflow() is bypassed, by setting `len` to a value that is greater than LONG_MAX (which is considered as a negative value after the cast), the function copy_from_user(), invoked a few lines later, will not perform any copy and return `len` as (len > INT_MAX) causing qat_vf_resume_write() to fail with -EFAULT.

2024-10-27firewire: core: fix invalid port index for parent deviceTakashi Sakamoto
In a commit 24b7f8e5cd65 ("firewire: core: use helper functions for self ID sequence"), the enumeration over self ID sequence was refactored with some helper functions with KUnit tests. These helper functions are guaranteed to work expectedly by the KUnit tests, however their application includes a mistake to assign invalid value to the index of port connected to parent device. This bug affects the case that any extra node devices which has three or more ports are connected to 1394 OHCI controller. In the case, the path to update the tree cache could hits WARN_ON(), and gets general protection fault due to the access to invalid address computed by the invalid value. This commit fixes the bug to assign correct port index.

2024-10-24drm/xe: Handle unreliable MMIO reads during forcewakeShuicheng Lin
In some cases, when the driver attempts to read an MMIO register, the hardware may return 0xFFFFFFFF. The current force wake path code treats this as a valid response, as it only checks the BIT. However, 0xFFFFFFFF should be considered an invalid value, indicating a potential issue. To address this, we should add a log entry to highlight this condition and return failure. The force wake failure log level is changed from notice to err to match the failure return value. v2 (Matt Brost): - set ret value (-EIO) to kick the error to upper layers v3 (Rodrigo): - add commit message for the log level promotion from notice to err v4: - update reviewed info Suggested-by: Alex Zuo <alex.zuo@intel.com> Signed-off-by: Shuicheng Lin <shuicheng.lin@intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Acked-by: Badal Nilawar <badal.nilawar@intel.com> Cc: Anshuman Gupta <anshuman.gupta@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241017221547.1564029-1-shuicheng.lin@intel.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> (cherry picked from commit a9fbeabe7226a3bf90f82d0e28a02c18e3c67447) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>

Previously it was hitting this 3 out of 1000 executions of warm reboot. After raising it to 500, 1000 warm reboot executions passed and it didn't fail. Due to the way xe_mmio_wait32() is implemented, the timeout is able to expire early when the register matches the expected value due to the wait increments starting small. So, the larger timeout value should have no effect during normal use cases. v2 (Jonathan): - rework the commit message v3 (Lucas): - add conclusive message for the fail rate and test case v4: - add suggested-by Suggested-by: Jia Yao <jia.yao@intel.com> Signed-off-by: Shuicheng Lin <shuicheng.lin@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Matthew Auld <matthew.auld@intel.com> Cc: Nirmoy Das <nirmoy.das@intel.com> Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Tested-by: Zongyao Bai <zongyao.bai@intel.com> Reviewed-by: Nirmoy Das <nirmoy.das@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241015161207.1373401-1-shuicheng.lin@intel.com (cherry picked from commit 2eb460ab9f4bc5b575f52568d17936da0af681d8) [ Fix conflict with gt->mmio ] Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>

2024-10-24ACPI: PRM: Clean up guid type in struct prm_handler_infoDan Carpenter
Clang 19 prints a warning when we pass &th->guid to efi_pa_va_lookup(): drivers/acpi/prmt.c:156:29: error: passing 1-byte aligned argument to 4-byte aligned parameter 1 of 'efi_pa_va_lookup' may result in an unaligned pointer access [-Werror,-Walign-mismatch] 156 | (void *)efi_pa_va_lookup(&th->guid, handler_info->handler_address); | ^ The problem is that efi_pa_va_lookup() takes a efi_guid_t and &th->guid is a regular guid_t. The difference between the two types is the alignment. efi_guid_t is a typedef. typedef guid_t efi_guid_t __aligned(__alignof__(u32)); It's possible that this a bug in Clang 19. Even though the alignment of &th->guid is not explicitly specified, it will still end up being aligned at 4 or 8 bytes. Anyway, as Ard points out, it's cleaner to change guid to efi_guid_t type and that also makes the warning go away.

But, if the synthetic device is moved to a new namespace after the VF registration, the VF won't be moved together.

2024-10-24net: dsa: microchip: disable EEE for KSZ879x/KSZ877x/KSZ876xTim Harvey
The well-known errata regarding EEE not being functional on various KSZ switches has been refactored a few times. Recently the refactoring has excluded several switches that the errata should also apply to. Disable EEE for additional switches with this errata and provide additional comments referring to the public errata document. The original workaround for the errata was applied with a register write to manually disable the EEE feature in MMD 7:60 which was being applied for KSZ9477/KSZ9897/KSZ9567 switch ID's. Then came commit 26dd2974c5b5 ("net: phy: micrel: Move KSZ9477 errata fixes to PHY driver") and commit 6068e6d7ba50 ("net: dsa: microchip: remove KSZ9477 PHY errata handling") which moved the errata from the switch driver to the PHY driver but only for PHY_ID_KSZ9477 (PHY ID) however that PHY code was dead code because an entry was never added for PHY_ID_KSZ9477 via MODULE_DEVICE_TABLE. This was apparently realized much later and commit 54a4e5c16382 ("net: phy: micrel: add Microchip KSZ 9477 to the device table") added the PHY_ID_KSZ9477 to the PHY driver but as the errata was only being applied to PHY_ID_KSZ9477 it's not completely clear what switches that relates to. Later commit 6149db4997f5 ("net: phy: micrel: fix KSZ9477 PHY issues after suspend/resume") breaks this again for all but KSZ9897 by only applying the errata for that PHY ID. Following that this was affected with commit 08c6d8bae48c("net: phy: Provide Module 4 KSZ9477 errata (DS80000754C)") which removes the blatant register write to MMD 7:60 and replaces it by setting phydev->eee_broken_modes = -1 so that the generic phy-c45 code disables EEE but this is only done for the KSZ9477_CHIP_ID (Switch ID). Lastly commit 0411f73c13af ("net: dsa: microchip: disable EEE for KSZ8567/KSZ9567/KSZ9896/KSZ9897.") adds some additional switches that were missing to the errata due to the previous changes. This commit adds an additional set of switches. Fixes: 0411f73c13af ("net: dsa: microchip: disable EEE for KSZ8567/KSZ9567/KSZ9896/KSZ9897.")

2024-10-24ata: libata: Set DID_TIME_OUT for commands that actually timed outNiklas Cassel
When ata_qc_complete() schedules a command for EH using ata_qc_schedule_eh(), blk_abort_request() will be called, which leads to req->q->mq_ops->timeout() / scsi_timeout() being called. scsi_timeout(), if the LLDD has no abort handler (libata has no abort handler), will set host byte to DID_TIME_OUT, and then call scsi_eh_scmd_add() to add the command to EH. Thus, when commands first enter libata's EH strategy_handler, all the commands that have been added to EH will have DID_TIME_OUT set. Commit e5dd410acb34 ("ata: libata: Clear DID_TIME_OUT for ATA PT commands with sense data") clears this bogus DID_TIME_OUT flag for all commands that reached libata's EH strategy_handler. libata has its own flag (AC_ERR_TIMEOUT), that it sets for commands that have not received a completion at the time of entering EH. ata_eh_worth_retry() has no special handling for AC_ERR_TIMEOUT, so by default timed out commands will get flag ATA_QCFLAG_RETRY set, and will be retried after the port has been reset (ata_eh_link_autopsy() always triggers a port reset if any command has AC_ERR_TIMEOUT set). For a command that has ATA_QCFLAG_RETRY set, while also having an error flag set (e.g. AC_ERR_TIMEOUT), ata_eh_finish() will not increment scmd->allowed, so the command will at most be retried scmd->allowed number of times (which by default is set to 3). However, scsi_eh_flush_done_q() will only retry commands for which scsi_noretry_cmd() returns false. For a command that has DID_TIME_OUT set, while also having either the FAILFAST flag set, or the command being a passthrough command, scsi_noretry_cmd() will return true. Thus, such a command will never be retried. Thus, make sure that libata sets SCSI's DID_TIME_OUT flag for commands that actually timed out (libata's AC_ERR_TIMEOUT flag), such that timed out commands will once again not be retried if they are also a FAILFAST or passthrough command.

2024-10-23PCI/pwrctl: Abandon QCom WCN probe on pre-pwrseq device-treesBartosz Golaszewski
Old device trees for some platforms already define wifi nodes for the WCN family of chips since before power sequencing was added upstream. These nodes don't consume the regulator outputs from the PMU, and if we allow this driver to bind to one of such "incomplete" nodes, we'll see a kernel log error about the infinite probe deferral. Extend the driver by adding a platform data struct matched against the compatible. This struct contains the pwrseq target string as well as a validation function called right after entering probe(). For Qualcomm WCN models, check the existence of the regulator supply property that indicates the DT is already using power sequencing and return -ENODEV if it's not there, indicating to the driver model that the device should not be bound to the pwrctl driver.

2024-10-23r8169: avoid unsolicited interruptsHeiner Kallweit
It was reported that after resume from suspend a PCI error is logged and connectivity is broken. Error message is: PCI error (cmd = 0x0407, status_errs = 0x0000) The message seems to be a red herring as none of the error bits is set, and the PCI command register value also is normal. Exception handling for a PCI error includes a chip reset what apparently brakes connectivity here. The interrupt status bit triggering the PCI error handling isn't actually used on PCIe chip versions, so it's not clear why this bit is set by the chip. Fix this by ignoring this bit on PCIe chip versions.
