2025-07-16ata: libata-eh: Simplify reset operation managementDamien Le Moal
Introduce struct ata_reset_operations to aggregate in a single structure the definitions of the 4 reset methods (prereset, softreset, hardreset and postreset) for a port. This new structure is used in struct ata_port to define the reset methods for a regular port (reset field) and for a port-multiplier port (pmp_reset field). A pointer to either of these fields replaces the 4 reset method arguments passed to ata_eh_recover() and ata_eh_reset(). The definition of the reset methods for all drivers is changed to use the reset and pmp_reset fields in struct ata_port_operations. A large number of files is modifed, but no functional changes are introduced.

2025-07-16ata: libata-eh: Remove ata_do_eh()Damien Le Moal
The only reason for ata_do_eh() to exist is that the two caller sites, ata_std_error_handler() and ata_sff_error_handler() may pass it a NULL hardreset operation so that the built-in (generic) hardreset operation for a driver is ignored if the adapter SCR access is not available. However, ata_std_error_handler() and ata_sff_error_handler() modifications of the hardreset port operation can easily be combined as they are mutually exclusive. That is, a driver using sata_std_hardreset() as its hardreset operation cannot use sata_sff_hardreset() and vice-versa. With this observation, ata_do_eh() can be removed and its code moved to ata_std_error_handler(). The condition used to ignore the built-in hardreset port operation is modified to be the one that was used in ata_sff_error_handler(). This requires defining a stub for the function sata_sff_hardreset() to avoid compilation errors when CONFIG_ATA_SFF is not enabled. Furthermore, instead of modifying the local hardreset operation definition, set the ATA_LFLAG_NO_HRST link flag to prevent the use of built-in hardreset methods for ports without a valid scr_read function. This flag is checked in ata_eh_reset() and if set, the hardreset method is ignored. This change simplifies ata_sff_error_handler() as this function now only needs to call ata_std_error_handler(). No functional changes. Signed-off-by: Damien Le Moal <dlemoal@kernel.org> Reviewed-by: Niklas Cassel <cassel@kernel.org> Reviewed-by: Martin K.

2025-07-15net: libwx: properly reset Rx ring descriptorJiawen Wu
When device reset is triggered by feature changes such as toggling Rx VLAN offload, wx->do_reset() is called to reinitialize Rx rings. The hardware descriptor ring may retain stale values from previous sessions. And only set the length to 0 in rx_desc[0] would result in building malformed SKBs. Fix it to ensure a clean slate after device reset. [ 549.186435] [ C16] ------------[ cut here ]------------ [ 549.186457] [ C16] kernel BUG at net/core/skbuff.c:2814!

2025-07-15net: libwx: fix the using of Rx buffer DMAJiawen Wu
The wx_rx_buffer structure contained two DMA address fields: 'dma' and 'page_dma'. However, only 'page_dma' was actually initialized and used to program the Rx descriptor. But 'dma' was uninitialized and used in some paths. This could lead to undefined behavior, including DMA errors or use-after-free, if the uninitialized 'dma' was used. Althrough such error has not yet occurred, it is worth fixing in the code.

2025-07-15PCI: Fix driver_managed_dma checkRobin Murphy
Since it's not currently safe to take device_lock() in the IOMMU probe path, that can race against really_probe() setting dev->driver before attempting to bind. The race itself isn't so bad, since we're only concerned with dereferencing dev->driver itself anyway, but sadly my attempt to implement the check with minimal churn leads to a kind of Time-of-Check to Time-of-Use (TOCTOU) issue, where dev->driver becomes valid after to_pci_driver(NULL) is already computed, and thus the check fails to work as intended. Will and I both hit this with the platform bus, but the pattern here is the same, so fix it for correctness too.

2025-07-15drm/amd/display: Disable CRTC degamma LUT for DCN401Melissa Wen
In DCN401 pre-blending degamma LUT isn't affecting cursor as in previous DCN version. As this is not the behavior close to what is expected for CRTC degamma LUT, disable CRTC degamma LUT property in this HW. Link: https://gitlab.freedesktop.org/drm/amd/-/issues/4176 --- When enabling HDR on KDE, it takes the first CRTC 1D LUT available and apply a color transformation (Gamma 2.2 -> PQ). AMD driver usually advertises a CRTC degamma LUT as the first CRTC 1D LUT, but it's actually applied pre-blending. In previous HW version, it seems to work fine because the 1D LUT was applied to cursor too, but DCN401 presents a different behavior and the 1D LUT isn't affecting the hardware cursor. To address the wrong gamma on cursor with HDR (see the link), I came up with this patch that disables CRTC degamma LUT in this hw, since it presents a different behavior than others. With this KDE sees CRTC regamma LUT as the first post-blending 1D LUT available. This is actually more consistent with AMD color pipeline. It was tested by the reporter, since I don't have the HW available for local testing and debugging.

SmartMux is a mechanism to switch the GPU being used for scanout in a hybrid configuration. This is used for devices with an eDP and two GPUs. This is only valid when the system has a physical switch (Multiplexer) in the board to switch between the two GPUs. When a graphically intensive workload like a game is being run, the system can be switch the active display to the dGPU, so that we can avoid copying the buffer from dGPU to APU for scanout. This helps with latency and FPS. When power consumption is preferred, the system can be switched to the APU.

2025-07-15drm/amd/display: limit clear_update_flags to dcn32 and aboveCharlene Liu
[why] dc has some code out of sync: dc_commit_updates_for_stream handles v1/v2/v3, but dc_update_planes_and_stream makes v1 asic to use v2. as a reression fix: limit clear_update_flags to dcn32 or newer asic. need to follow up that v1 asic using v2 issue.

2025-07-15drm/amd/display: Refactor DSC cap calculationsDillon Varone
[WHY] DSC block level should only be responsible for reporting single DSC instance capabilities. Factoring in ODM combine requirements should be handled in dc_dsc.c. Both components should acquire clocks from clk_mgr to determine throughput capabilities instead of relying on hard coded values as these can differ by SoC and SKU. [HOW] 1) Add dsc_get_single_enc_caps to acquire single DSC instance capabilities (replacing dsc_get_enc_caps), factoring in DSCCLK 2) add build_dsc_enc_caps to combine single DSC instance capabilities 3) account for max pixel rate per pipe (DISPCLK) when calculating minimum slice count Reviewed-by: Wenjing Liu <wenjing.liu@amd.com> Signed-off-by: Dillon Varone <dillon.varone@amd.com> Signed-off-by: Ivan Lipski <ivan.lipski@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
