2023-10-12net/mlx5: Bridge, fix peer entry ageing in LAG modeVlad Buslov
With current implementation in single FDB LAG mode all packets are processed by eswitch 0 rules. As such, 'peer' FDB entries receive the packets for rules of other eswitches and are responsible for updating the main entry by sending SWITCHDEV_FDB_ADD_TO_BRIDGE notification from their background update wq task. However, this introduces a race condition when non-zero eswitch instance decides to delete a FDB entry, sends SWITCHDEV_FDB_DEL_TO_BRIDGE notification, but another eswitch's update task refreshes the same entry concurrently while its async delete work is still pending on the workque. In such case another SWITCHDEV_FDB_ADD_TO_BRIDGE event may be generated and entry will remain stuck in FDB marked as 'offloaded' since no more SWITCHDEV_FDB_DEL_TO_BRIDGE notifications are sent for deleting the peer entries. Fix the issue by synchronously marking deleted entries with MLX5_ESW_BRIDGE_FLAG_DELETED flag and skipping them in background update job.

2023-10-12net/mlx5: E-switch, register event handler before arming the eventShay Drory
Currently, mlx5 is registering event handler for vport context change event some time after arming the event. this can lead to missing an event, which will result in wrong rules in the FDB. Hence, register the event handler before arming the event. This solution is valid since FW is sending vport context change event only on vports which SW armed, and SW arming the vport when enabling it, which is done after the FDB has been created.

2023-10-12net/mlx5: Perform DMA operations in the right locationsShay Drory
The cited patch change mlx5 driver so that during probe DMA operations were performed before pci_enable_device(), and during teardown DMA operations were performed after pci_disable_device(). DMA operations require PCI to be enabled. Hence, The above leads to the following oops in PPC systems[1]. On s390x systems, as reported by Niklas Schnelle, this is a problem because mlx5_pci_init() is where the DMA and coherent mask is set but mlx5_cmd_init() already does a dma_alloc_coherent(). Thus a DMA allocation is done during probe before the correct mask is set. This causes probe to fail initialization of the cmdif SW structs on s390x after that is converted to the common dma-iommu code. This is because on s390x DMA addresses below 4 GiB are reserved on current machines and unlike the old s390x specific DMA API implementation common code enforces DMA masks. Fix it by performing the DMA operations during probe after pci_enable_device() and after the dma mask is set, and during teardown before pci_disable_device().

2023-10-12drm/panel: Move AUX B116XW03 out of panel-edp back to panel-simpleDouglas Anderson
In commit 5f04e7ce392d ("drm/panel-edp: Split eDP panels out of panel-simple") I moved a pile of panels out of panel-simple driver into the newly created panel-edp driver. One of those panels, however, shouldn't have been moved. As is clear from commit e35e305eff0f ("drm/panel: simple: Add AUO B116XW03 panel support"), AUX B116XW03 is an LVDS panel. It's used in exynos5250-snow and exynos5420-peach-pit where it's clear that the panel is hooked up with LVDS. Furthermore, searching for datasheets I found one that makes it clear that this panel is LVDS. As far as I can tell, I got confused because in commit 88d3457ceb82 ("drm/panel: auo,b116xw03: fix flash backlight when power on") Jitao Shi added "DRM_MODE_CONNECTOR_eDP". That seems wrong. Looking at the downstream ChromeOS trees, it seems like some Mediatek boards are using a panel that they call "auo,b116xw03" that's an eDP panel. The best I can guess is that they actually have a different panel that has similar timing. If so then the proper panel should be used or they should switch to the generic "edp-panel" compatible. When moving this back to panel-edp, I wasn't sure what to use for .bus_flags and .bus_format and whether to add the extra "enable" delay from commit 88d3457ceb82 ("drm/panel: auo,b116xw03: fix flash backlight when power on"). I've added formats/flags/delays based on my (inexpert) analysis of the datasheet. These are untested. NOTE: if/when this is backported to stable, we might run into some trouble. Specifically, before 474c162878ba ("arm64: dts: mt8183: jacuzzi: Move panel under aux-bus") this panel was used by "mt8183-kukui-jacuzzi", which assumed it was an eDP panel. I don't know what to suggest for that other than someone making up a bogus panel for jacuzzi that's just for the stable channel.

2023-10-12drm/bridge: ti-sn65dsi86: Associate DSI device lifetime with auxiliary deviceStephen Boyd
The kernel produces a warning splat and the DSI device fails to register in this driver if the i2c driver probes, populates child auxiliary devices, and then somewhere in ti_sn_bridge_probe() a function call returns -EPROBE_DEFER. When the auxiliary driver probe defers, the dsi device created by devm_mipi_dsi_device_register_full() is left registered because the devm managed device used to manage the lifetime of the DSI device is the parent i2c device, not the auxiliary device that is being probed. Associate the DSI device created and managed by this driver to the lifetime of the auxiliary device, not the i2c device, so that the DSI device is removed when the auxiliary driver unbinds. Similarly change the device pointer used for dev_err_probe() so the deferred probe errors are associated with the auxiliary device instead of the parent i2c device so we can narrow down future problems faster.

Currently, the logic to return an ath11k_sta pointer, given a ieee80211_sta pointer, uses typecasting throughout the driver. In general, conversion functions are preferable to typecasting since using a conversion function allows the compiler to validate the types of both the input and output parameters. ath11k already defines a conversion function ath11k_vif_to_arvif() for a similar conversion.

2023-10-12nvme: rework NVME_AUTH Kconfig selectionHannes Reinecke
Having a single Kconfig symbol NVME_AUTH conflates the selection of the authentication functions from nvme/common and nvme/host, causing kbuild robot to complain when building the nvme target only. So introduce a Kconfig symbol NVME_HOST_AUTH for the nvme host bits and use NVME_AUTH for the common functions only. And move the CRYPTO selection into nvme/common to make it easier to read.

2023-10-12platform/x86/amd/pmc: Add dump_custom_stb module parameterShyam Sundar S K
There have been instances when the default size (1M) of the STB is not sufficient to get the complete traces of the failure. In such scenarios we can use a module_param to enable full trace that shall contain more debugging data. This is not a regular case and hence not enabling this capability by default. With this change, there will be two cases on how the driver fetches the stb data: 1) A special case (proposed now) - which is required only for certain platforms. Here, a new module param will be supplied to the driver that will have a special PMFW supporting enhanced dram sizes for getting the stb data. Without the special PMFW support, just setting the module param will not help to get the enhanced stb data. To adapt to this change, we will have a new amd_pmc_stb_handle_efr() to handle enhanced firmware reporting mechanism. Note that, since num_samples based r/w pointer offset calculation is not required for enhanced firmware reporting we will have this mailbox command sent only in case of regular STB cases. 2) Current code branch which fetches the stb data based on the parameters like the num_samples, fsize and the r/w pointer.

2023-10-12platform/x86/amd/pmc: Handle overflow cases where the num_samples range is ↵Shyam Sundar S K
higher In amd_pmc_stb_debugfs_open_v2(), the stb buffer is created based on the num_samples and the read/write pointer offset. This holds good when the num_samples reported by PMFW is less than S2D_TELEMETRY_BYTES_MAX; where the stb buffer gets filled from 0th position until S2D_TELEMETRY_BYTES_MAX - 1 based on the read/write pointer offset. But when the num_samples exceeds the S2D_TELEMETRY_BYTES_MAX, the current code does not handle it well as it does not account for the cases where the stb buffer has to filled up as a circular buffer. Handle this scenario into two cases, where first memcpy will have the samples from location: (num_samples % S2D_TELEMETRY_BYTES_MAX) - (S2D_TELEMETRY_BYTES_MAX - 1) and next memcpy will have the newest ones i.e. 0 - (num_samples % S2D_TELEMETRY_BYTES_MAX - 1) Suggested-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sanket Goswami <Sanket.Goswami@amd.com> Signed-off-by: Shyam Sundar S K <Shyam-sundar.S-k@amd.com> Link: https://lore.kernel.org/r/20231010145003.139932-2-Shyam-sundar.S-k@amd.com [ij: renamed flex_arr -> stb_data_arr] Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>

Currently in amd_pmc_stb_debugfs_open_v2() the buffer size is assumed to be fixed and a second call to amd_pmc_stb_debugfs_open_v2() may race with a process holding open another fd.

Yoga Tablet 2 series (v3) On the Lenovo Yoga Tablet 2 830 / 1050 there are 2 problems: 1. The I2C MIPI sequence elements reference bus 3. ACPI has I2C1 - I2C7 which under Linux become bus 0 - 6. And the MIPI sequence reference to bus 3 is indented for I2C3 which is bus 2 under Linux. This leads to errors like these: [ 178.244049] i2c_designware 80860F41:03: controller timed out [ 178.245703] i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (169) There are 3 timeouts when the panel is on, delaying waking up the screen on a key press by 3 seconds. Note mipi_exec_i2c() cannot just subtract 1 from the bus given in the I2C MIPI sequence element. Since on other devices the I2C bus-numbers used in the MIPI sequences do actually start at 0. 2. width_/height_mm contain a bogus 192mm x 120mm size. This is especially a problem on the 8" 830 version which uses a 10:16 portrait screen where as the bogus size is 16:10. Add a DMI quirk to override the I2C bus and the panel size with the correct values. Note both the 10" 1050 models as well as the 8" 830 models use the same mainboard and thus the same DMI strings. The 10" 1050 uses a 1920x1200 landscape screen, where as the 8" 830 uses a 1200x1920 portrait screen, so the quirk handling uses the display resolution to detect the model. v2: - Also override i2c_bus_num to fix mipi_exec_i2c() timeouts v3: - Add Closes tag to gitlab issue with drm.debug=0xe, VBT info Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9379 Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230920195613.304091-3-hdegoede@redhat.com
