- Tegra194 and Tegra234 HDA is not compatible with Tegra30, hence update them as standalone compatibles. Also, add necessary logic to the binding doc as HDA clocks and resets for Tegra194 and Tegra234 are different from Tegra30. This fixes below dtbs_check errors: - compatible: 'oneOf' conditional failed, one must be fixed: ['nvidia,tegra194-hda'] is too short 'nvidia,tegra30-hda' was expected 'nvidia,tegra132-hda' was expected - compatible: 'oneOf' conditional failed, one must be fixed: ['nvidia,tegra234-hda'] is too short 'nvidia,tegra30-hda' was expected 'nvidia,tegra132-hda' was expected - hda@3510000: clock-names:1: 'hda2hdmi' was expected - hda@3510000: reset-names:1: 'hda2hdmi' was expected Signed-off-by: Sheetal <sheetal@nvidia.com> Reviewed-by: Rob Herring (Arm) <robh@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20250512064258.1028331-2-sheetal@nvidia.com

2025-05-15PCI: Add debugfs support for exposing PTM contextManivannan Sadhasivam
Precision Time Management (PTM) mechanism defined in PCIe spec r6.0, sec 6.21 allows precise coordination of timing information across multiple components in a PCIe hierarchy with independent local time clocks. PCI core already supports enabling PTM in the root port and endpoint devices through PTM Extended Capability registers. But the PTM context supported by the PTM capable components such as Root Complex (RC) and Endpoint (EP) controllers were not exposed as of now. Part of the reason is that the spec doesn't define how the context information is exposed to the software and left it to the vendor implementation. So there is no standardized way to get access to the context information and each vendor have defined their own way. This commit adds debugfs support to expose the PTM context to userspace from both PCIe RC and EP controllers. Since the context information is exposed in a vendor specific way, the debugfs interface allows the controller drivers to implement callbacks for each attribute, to be called by the generic PTM driver. The Controller drivers are expected to call pcie_ptm_create_debugfs() to create the debugfs attributes for the PTM context and call pcie_ptm_destroy_debugfs() to destroy them. The drivers should also populate the relevant callbacks in the 'struct pcie_ptm_ops' structure based on the controller implementation. Below PTM context are exposed through debugfs: PCIe RC ======= 1. PTM Local clock 2. PTM T2 timestamp 3. PTM T3 timestamp 4. PTM Context valid PCIe EP ======= 1. PTM Local clock 2. PTM T1 timestamp 3. PTM T4 timestamp 4. PTM Master clock 5.

2025-05-15vfs: Add sysctl vfs_cache_pressure_denom for bulk file operationsYafang Shao
On our HDFS servers with 12 HDDs per server, a HDFS datanode[0] startup involves scanning all files and caching their metadata (including dentries and inodes) in memory. Each HDD contains approximately 2 million files, resulting in a total of ~20 million cached dentries after initialization. To minimize dentry reclamation, we set vfs_cache_pressure to 1. Despite this configuration, memory pressure conditions can still trigger reclamation of up to 50% of cached dentries, reducing the cache from 20 million to approximately 10 million entries. During the subsequent cache rebuild period, any HDFS datanode restart operation incurs substantial latency penalties until full cache recovery completes. To maintain service stability, we need to preserve more dentries during memory reclamation. The current minimum reclaim ratio (1/100 of total dentries) remains too aggressive for our workload. This patch introduces vfs_cache_pressure_denom for more granular cache pressure control. The configuration [vfs_cache_pressure=1, vfs_cache_pressure_denom=10000] effectively maintains the full 20 million dentry cache under memory pressure, preventing datanode restart performance degradation.

Add the 'iommus' property to the Tegra QSPI device tree binding. The property is needed for Tegra234 when using the internal DMA controller, and is not supported on other Tegra chips, as DMA is handled by an external controller.
