2025-05-14net: ethernet: mtk_eth_soc: fix typo for declaration MT7988 ESW capabilityBo-Cun Chen
Since MTK_ESW_BIT is a bit number rather than a bitmap, it causes MTK_HAS_CAPS to produce incorrect results. This leads to the ETH driver not declaring MAC capabilities correctly for the MT7988 ESW.

2025-05-14octeontx2-pf: macsec: Fix incorrect max transmit size in TX secySubbaraya Sundeep
MASCEC hardware block has a field called maximum transmit size for TX secy. Max packet size going out of MCS block has be programmed taking into account full packet size which has L2 header,SecTag and ICV. MACSEC offload driver is configuring max transmit size as macsec interface MTU which is incorrect. Say with 1500 MTU of real device, macsec interface created on top of real device will have MTU of 1468(1500 - (SecTag + ICV)). This is causing packets from macsec interface of size greater than or equal to 1468 are not getting transmitted out because driver programmed max transmit size as 1468 instead of 1514(1500 + ETH_HDR_LEN).

2025-05-15tpm: tis: Double the timeout B to 4sMichal Suchanek
With some Infineon chips the timeouts in tpm_tis_send_data (both B and C) can reach up to about 2250 ms. Timeout C is retried since commit de9e33df7762 ("tpm, tpm_tis: Workaround failed command reception on Infineon devices") Timeout B still needs to be extended. The problem is most commonly encountered with context related operation such as load context/save context. These are issued directly by the kernel, and there is no retry logic for them. When a filesystem is set up to use the TPM for unlocking the boot fails, and restarting the userspace service is ineffective. This is likely because ignoring a load context/save context result puts the real TPM state and the TPM state expected by the kernel out of sync.

2025-05-14drm/mediatek: mtk_drm_drv: Unbind secondary mmsys components on errAngeloGioacchino Del Regno
When calling component_bind_all(), if a component that is included in the list fails, all of those that have been successfully bound will be unbound, but this driver has two components lists for two actual devices, as in, each mmsys instance has its own components list. In case mmsys0 (or actually vdosys0) is able to bind all of its components, but the secondary one fails, all of the components of the first are kept bound, while the ones of mmsys1/vdosys1 are correctly cleaned up. This is not right because, in case of a failure, the components are re-bound for all of the mmsys/vdosys instances without caring about the ones that were previously left in a bound state. Fix that by calling component_unbind_all() on all of the previous component masters that succeeded binding all subdevices when any of the other masters errors out.

2025-05-14drm/mediatek: Fix kobject put for component sub-driversAngeloGioacchino Del Regno
In function mtk_drm_get_all_drm_priv(), this driver is incrementing the refcount for the sub-drivers of mediatek-drm with a call to device_find_child() when taking a reference to all of those child devices. When the component bind fails multiple times this results in a refcount_t overflow, as the reference count is never decremented: fix that by adding a call to put_device() for all of the mmsys devices in a loop, in error cases of mtk_drm_bind() and in the mtk_drm_unbind() callback.

2025-05-14drm/mediatek: mtk_drm_drv: Fix kobject put for mtk_mutex device ptrAngeloGioacchino Del Regno
This driver is taking a kobject for mtk_mutex only once per mmsys device for each drm-mediatek driver instance, differently from the behavior with other components, but it is decrementing the kobj's refcount in a loop and once per mmsys: this is not right and will result in a refcount_t underflow warning when mediatek-drm returns multiple probe deferrals in one boot (or when manually bound and unbound). Besides that, the refcount for mutex_dev was not decremented for error cases in mtk_drm_bind(), causing another refcount_t warning but this time for overflow, when the failure happens not during driver bind but during component bind. In order to fix one of the reasons why this is happening, remove the put_device(xx->mutex_dev) loop from the mtk_drm_kms_init()'s put_mutex_dev label (and drop the label) and add a single call to correctly free the single incremented refcount of mutex_dev to the mtk_drm_unbind() function to fix the refcount_t underflow. Moreover, add the same call to the error cases in mtk_drm_bind() to fix the refcount_t overflow.

2025-05-14drm/xe: Add WA BB to capture active context utilizationUmesh Nerlige Ramappa
Context Timestamp (CTX_TIMESTAMP) in the LRC accumulates the run ticks of the context, but only gets updated when the context switches out. In order to check how long a context has been active before it switches out, two things are required: (1) Determine if the context is running: To do so, we program the WA BB to set an initial value for CTX_TIMESTAMP in the LRC. The value chosen is 1 since 0 is the initial value when the LRC is initialized. During a query, we just check for this value to determine if the context is active. If the context switched out, it would overwrite this location with the actual CTX_TIMESTAMP MMIO value. Note that WA BB runs as the last part of the context restore, so reusing this LRC location will not clobber anything. (2) Calculate the time that the context has been active for: The CTX_TIMESTAMP ticks only when the context is active. If a context is active, we just use the CTX_TIMESTAMP MMIO as the new value of utilization. While doing so, we need to read the CTX_TIMESTAMP MMIO for the specific engine instance. Since we do not know which instance the context is running on until it is scheduled, we also read the ENGINE_ID MMIO in the WA BB and store it in the PPHSWP. Using the above 2 instructions in a WA BB, capture active context utilization. v2: (Matt Brost) - This breaks TDR, fix it by saving the CTX_TIMESTAMP register "drm/xe: Save CTX_TIMESTAMP mmio value instead of LRC value" - Drop tile from LRC if using gt "drm/xe: Save the gt pointer in LRC and drop the tile" v3: - Remove helpers for bb_per_ctx_ptr (Matt) - Add define for context active value (Matt) - Use 64 bit CTX TIMESTAMP for platforms that support it.

2025-05-14drm/amdgpu: Fix circular locking in userq creationJesse.Zhang
A circular locking dependency was detected between the global `adev->userq_mutex` and per-file `userq_mgr->userq_mutex` when creating user queues. The issue occurs because: 1. `amdgpu_userq_suspend()` and `amdgpu_userq_resume` take `adev->userq_mutex` first, then `userq_mgr->userq_mutex` 2. While `amdgpu_userq_create()` takes them in reverse order This patch resolves the issue by: 1. Moving the `adev->userq_mutex` lock earlier in `amdgpu_userq_create()` to cover the `amdgpu_userq_ensure_ev_fence()` call 2. Releasing it after we're done with both queue creation and the scheduling halt check v2: remove unused adev->userq_mutex lock (Prike) Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Reviewed-by: Prike Liang <Prike.Liang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
