2026-04-03crypto: qat - replace scnprintf() with sysfs_emit()Atharv Dubey
Replace scnprintf() with sysfs_emit() in the three RAS error counter sysfs show callbacks. sysfs_emit() is the recommended API for sysfs show functions as per Documentation/filesystems/sysfs.rst; it enforces the PAGE_SIZE limit implicitly, removing the need to pass it explicitly.

2026-04-03crypto: qat - fix type mismatch in RAS sysfs show functionsGiovanni Cabiddu
ADF_RAS_ERR_CTR_READ() expands to atomic_read(), which returns int. The local variable 'counter' was declared as 'unsigned long', causing a type mismatch on the assignment. The format specifier '%ld' was consequently wrong in two ways: wrong length modifier and wrong signedness. Use int to match the return type of atomic_read() and update the format specifier to '%d' accordingly.

2026-04-03crypto: qat - fix compression instance leakGiovanni Cabiddu
qat_comp_alg_init_tfm() acquires a compression instance via qat_compression_get_instance_node() before calling qat_comp_build_ctx() to initialize the compression context. If qat_comp_build_ctx() fails, the function returns an error without releasing the compression instance, causing a resource leak. When qat_comp_build_ctx() fails, release the compression instance with qat_compression_put_instance() and clear the context to avoid leaving a stale reference to the released instance. The issue was introduced when build_deflate_ctx() (which always returned void) was replaced by qat_comp_build_ctx() (which can return an error) without adding error handling for the failure path.

2026-04-02vfio/pci: Require vfio_device_ops.nameAlex Williamson
vfio-pci-core code makes use of the vfio_device_ops.name field in order to set a default driver_override for VFs created on a user-owned PF. This avoids default driver matching, which might otherwise bind those VFs to native drivers. The mechanism for this currently uses kasprintf(), which will set driver_override to the literal "(null)" if name is NULL. This is effective in sequestering the device, but presents a challenging debug situation to differentiate driver_override being set to "(null)" versus being NULL and interpreted as "(null)" via the sysfs show attribute. There's also a tree-wide effort to convert to generic driver_override support, where passing NULL will generate an error, resulting in a WARN_ON without setting any driver_override. All drivers making use of vfio-pci-core already set a driver name, therefore by requiring this behavior, all of these corner cases are rendered moot. This is expected to have no impact on current in-kernel drivers.

2026-04-02drm/amd/display: Wire up dcn10_dio_construct() for all pre-DCN401 generationsIonut Nechita
Description: - Commit b82f0759346617b2 ("drm/amd/display: Migrate DIO registers access from hwseq to dio component") moved DIO_MEM_PWR_CTRL register access behind the new dio abstraction layer but only created the dio object for DCN 4.01. On all other generations (DCN 10/20/21/201/30/301/302/303/ 31/314/315/316/32/321/35/351/36), the dio pointer is NULL, causing the register write to be silently skipped. This results in AFMT HDMI memory not being powered on during init_hw, which can cause HDMI audio failures and display issues on affected hardware including Renoir/Cezanne (DCN 2.1) APUs that use dcn10_init_hw. Call dcn10_dio_construct() in each older DCN generation's resource.c to create the dio object, following the same pattern as DCN 4.01. This ensures the dio pointer is non-NULL and the mem_pwr_ctrl callback works through the dio abstraction for all DCN generations.

The test in stmmac_xmit() to see whether we should pass the skbuff to stmmac_tso_xmit() is more complex than it needs to be. This test can be simplified by storing the mask of GSO types that we will pass, and setting it according to the enabled features. Note that "tso" is a mis-nomer since commit b776620651a1 ("net: stmmac: Implement UDP Segmentation Offload"). Also note that this commit controls both via the TSO feature. We preserve this behaviour in this commit. Also, this commit unconditionally accessed skb_shinfo(skb)->gso_type for all frames, even when skb_is_gso() was false. This access is eliminated.

2026-04-02net: stmmac: move check for hardware checksum supportedRussell King (Oracle)
Add a check in .ndo_features_check() to indicate whether hardware checksum can be performed on the skbuff. Where hardware checksum is not supported - either because the channel does not support Tx COE or the skb isn't suitable (stmmac uses a tighter test than can_checksum_protocol()) we also need to disable TSO, which will be done by harmonize_features() in net/core/dev.c This fixes a bug where a channel which has COE disabled may still receive TSO skbuffs.

2026-04-02net: stmmac: move TSO VLAN tag insertion to core codeRussell King (Oracle)
stmmac_tso_xmit() checks whether the skbuff is trying to offload vlan tag insertion to hardware, which from the comment in the code appears to be buggy when the TSO feature is used. Rather than stmmac_tso_xmit() inserting the VLAN tag, handle this in stmmac_features_check() which will then use core net code to handle this.

2026-04-02net: stmmac: fix TSO support when some channels have TBS availableRussell King (Oracle)
According to the STM32MP25xx manual, which is dwmac v5.3, TBS (time based scheduling) is not permitted for channels which have hardware TSO enabled. Intel's commit 5e6038b88a57 ("net: stmmac: fix TSO and TBS feature enabling during driver open") concurs with this, but it is incomplete. This commit avoids enabling TSO support on the channels which have TBS available, which, as far as the hardware is concerned, means we do not set the TSE bit in the DMA channel's transmit control register. However, the net device's features apply to all queues(channels), which means these channels may still be handed TSO skbs to transmit, and the driver will pass them to stmmac_tso_xmit(). This will generate the descriptors for TSO, even though the channel has the TSE bit clear. Fix this by checking whether the queue(channel) has TBS available, and if it does, fall back to software GSO support.

2026-04-02net: stmmac: fix .ndo_fix_features()Russell King (Oracle)
netdev features documentation requires that .ndo_fix_features() is stateless: it shouldn't modify driver state. Yet, stmmac_fix_features() does exactly that, changing whether GSO frames are processed by the driver. Move this code to stmmac_set_features() instead, which is the correct place for it. We don't need to check whether TSO is supported; this is already handled via the setup of netdev->hw_features, and we are guaranteed that if netdev->hw_features indicates that a feature is not supported, .ndo_set_features() won't be called with it set.

2026-04-02net: stmmac: fix channel TSO enable on resumeRussell King (Oracle)
Rather than configuring the channels depending on whether GSO/TSO is currently enabled by the user, always enable if the hardware has TSO support and the platform wants TSO to be enabled. This avoids the channel TSO enable bit being disabled after a resume when the user has disabled TSO features. This will cause problems when the user re-enables TSO.
