ALSA: hda/intel: enforce stricter period-size alignment for Intel NVL

2026-04-08T12:09:33+00:00

Intel ACE4 based products set more strict constraints on HDA BDLE start address and length alignment. Modify capability flags to drop AZX_DCAPS_NO_ALIGN_BUFSIZE for Intel Nova Lake platforms.

ALSA: hda/intel: Add MSI X870E Tomahawk to denylist by DMI ID

2026-03-28T09:32:53+00:00

This motherboard uses USB audio instead, causing this driver to complain about "no codecs found!". Add it to the denylist to silence the warning. The first attempt only matched on the PCI device, but this caused issues for some laptops, so DMI match against the board as well.

ALSA: hda/intel: increase default bdl_pos_adj for Nvidia controllers

2026-02-25T14:56:57+00:00

The default bdl_pos_adj of 32 for Nvidia HDA controllers is insufficient on GA102 (and likely other recent Nvidia GPUs) after S3 suspend/resume. The controller's DMA timing degrades after resume, causing premature IRQ detection in azx_position_ok() which results in silent HDMI/DP audio output despite userspace reporting a valid playback state and correct ELD data. Increase bdl_pos_adj to 64 for AZX_DRIVER_NVIDIA, matching the value already used by Intel Apollo Lake for the same class of timing issue.

ALSA: hda/intel: Make MSI address limit based on the device DMA limit

2026-01-31T00:11:48+00:00

The hda/intel driver restricts the MSI message address for devices which do not advertise full 64-bit DMA address space support to 32-bit due to the former restrictions of the PCI/MSI code which only allowed either 32-bit or a full 64-bit address range. This does not work on platforms which have a MSI doorbell address above the 32-bit boundary but do not support the full 64 bit address range. The PCI/MSI core converted this binary decision to a DMA_BIT_MASK() based decision, which allows to describe the device limitations precisely. Convert the driver to provide the exact DMA address limitations to the PCI/MSI core. That allows devices which do not support the full 64-bit address space to work on platforms which have a MSI doorbell address above the 32-bit limit as long as it is within the hardware's addressable range.

PCI/MSI: Convert the boolean no_64bit_msi flag to a DMA address mask

2026-01-31T00:11:48+00:00

Some PCI devices have PCI_MSI_FLAGS_64BIT in the MSI capability, but implement less than 64 address bits. This breaks on platforms where such a device is assigned an MSI address higher than what's supported. Currently, no_64bit_msi bit is set for these devices, meaning that only 32-bit MSI addresses are allowed for them. However, on some platforms the MSI doorbell address is above the 32-bit limit but within the addressable range of the device. As a first step to enable MSI on those combinations of devices and platforms, convert the boolean no_64bit_msi flag to a DMA mask and fixup the affected usage sites: - no_64bit_msi = 1 -> msi_addr_mask = DMA_BIT_MASK(32) - no_64bit_msi = 0 -> msi_addr_mask = DMA_BIT_MASK(64) - if (no_64bit_msi) -> if (msi_addr_mask < DMA_BIT_MASK(64)) Since no values other than DMA_BIT_MASK(32) and DMA_BIT_MASK(64) are used, this is functionally equivalent. This prepares for changing the binary decision between 32 and 64 bit to a DMA mask based decision which allows to support systems which have a DMA address space less than 64bit but a MSI doorbell address above the 32-bit limit.

ASoC: Fix acronym for Intel Gemini Lake

2025-12-15T14:08:47+00:00

While the used GML is consistent with the pattern for other Intel * Lake SoCs, the de facto use is GLK. Update the acronym and users accordingly. Note, a handful of the drivers for Gemini Lake in the Linux kernel use GLK already (LPC, MEI, pin control, SDHCI, ...) and even some in ASoC. The only ones in this patch used the inconsistent one.
