Once a device is registered, changing the module parameter only affects future devices, leaving no direct way to confirm the effective policy for an existing device. Add a pci debugfs directory under the VFIO device debugfs root and report the per-device nointxmask and disable_idle_d3 values. These are read-only debugfs views and use the same Y/N bool output convention as the module parameters. Read-only vfio-pci parameters, such as disable_vga, are not exposed here because they cannot drift from the latched device value, therefore the existing module parameter exposure via sysfs is sufficient. Note that while only vfio-pci currently provides these options, the implementation is in vfio-pci-core and therefore properly reflects the device policy in the core, regardless of driver.

This is applicable to vfree() and to the releasing of frozen pages - "mm/damon: introduce DAMOS failed region quota charge ratio" (SeongJae Park) Address a DAMOS usability issue: The DAMOS quota often exhausts prematurely because it charges for all memory attempted, causing slow and inconsistent performance when actions fail on unreclaimable memory. To fix this, a new feature lets users set a smaller, flexible quota charge ratio (via a numerator and denominator) for failed regions.

The NXP QuickEngine gets modern MSI support, which allows some cleanups to the GICv3 irqchip chip driver - A new SoC specific driver for the Renesas R-Car MFIS unit is added, encapsulating support for the on-chip mailbox and hwspinlock implementations that are not easily separated into individual drivers - The Qualcomm SoC drivers add support for additional SoC implementations, and flexibility around power management for the serial-engine driver as well as probing the LLCC driver using custom hardware descriptions inside of the device itself. - Added support for the Samsung thermal management unit - A cleanup to the Tegra 'PMC' driver interfaces to remove legacy APIs and allow multiple PMC instances everywhere. - Updates to the TI SCI and KNAS drivers to improve suspend/resume support. - Minor driver changes for mediatek, xilinx, allwinner, aspeed, tegra, broadcom, amd, microchip and starfive specific drivers - Memory controller updates for Tegra and Renesas for additional SoC types and other improvements. - Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces, to update driver probing, object lifetimes and address minor bugs" * tag 'soc-drivers-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (189 commits) Revert "firmware: zynqmp: Add dynamic CSU register discovery and sysfs interface" Revert "Documentation: ABI: add sysfs interface for ZynqMP CSU registers" memory: tegra234: drop dead NULL check in tegra234_mc_icc_aggregate() memory: tegra264: drop redundant tegra264_mc_icc_aggregate() memory: tegra186-emc: stop borrowing MC aggregate hook for EMC soc: aspeed: cleanup dead default for ASPEED_SOCINFO firmware: tegra: bpmp: Add support for multi-socket platforms firmware: tegra: bpmp: Propagate debugfs errors soc/tegra: pmc: Add Tegra238 support soc/tegra: pmc: Restrict power-off handler to Nexus 7 soc/tegra: pmc: Populate powergate debugfs only when needed soc/tegra: pmc: Move legacy code behind CONFIG_ARM guard soc/tegra: pmc: Remove unused legacy functions soc/tegra: pmc: Create PMC context dynamically firmware: samsung: acpm: remove compile-testing stubs firmware: samsung: acpm: Add devm_acpm_get_by_phandle helper firmware: samsung: acpm: Add TMU protocol support firmware: samsung: acpm: Make acpm_ops const and access via pointer firmware: samsung: acpm: Drop redundant _ops suffix in acpm_ops members firmware: samsung: acpm: Annotate rx_data->cmd with __counted_by_ptr ... 2026-06-17T10:30:14+00:00 Armin Wolf W_Armin@gmx.de 2026-05-27T00:14:22+00:00 urn:sha1:938fda9671dd07196f4e591d30977b2e69d8f320 The "multi_max_intensity" sysfs attribute was not included in kernel 7.1, so update the KernelVersion and Date tags accordingly.
