genirq/irq_sim: Initialize work context pointers properly

2025-07-10T14:08:48Z

[ Upstream commit 8a2277a3c9e4cc5398f80821afe7ecbe9bdf2819 ] Initialize `ops` member's pointers properly by using kzalloc() instead of kmalloc() when allocating the simulation work context. Otherwise the pointers contain random content leading to invalid dereferencing.

genirq/msi: Prevent NULL pointer dereference in msi_domain_debug_show()

2025-04-30T21:25:10Z

irq_domain_debug_show_one() calls msi_domain_debug_show() with a non-NULL domain pointer and a NULL irq_data pointer. irq_debug_show_data() calls it with a NULL domain pointer. The domain pointer is not used, but the irq_data pointer is required to be non-NULL and lacks a NULL pointer check. Add the missing NULL pointer check to ensure there is a non-NULL irq_data pointer in msi_domain_debug_show() before dereferencing it.

genirq/migration: Use irqd_get_parent_data() in irq_force_complete_move()

2025-04-04T15:08:36Z

Frank reported, that the common irq_force_complete_move() breaks the out of tree build of ia64. The reason is that ia64 uses the migration code, but does not have hierarchical interrupt domains enabled. This went unnoticed in mainline as both x86 and RISC-V have hierarchical domains enabled. Not that it matters for mainline, but it's still inconsistent. Use irqd_get_parent_data() instead of accessing the parent_data field directly. The helper returns NULL when hierarchical domains are disabled otherwise it accesses the parent_data field of the domain. No functional change.

irqdomain: Rename irq_get_default_host() to irq_get_default_domain()

2025-04-04T14:39:10Z

Naming interrupt domains host is confusing at best and the irqdomain code uses both domain and host inconsistently. Therefore rename irq_get_default_host() to irq_get_default_domain().

Pull irq driver updates from Thomas Gleixner: - Support for hard indices on RISC-V. The hart index identifies a hart (core) within a specific interrupt domain in RISC-V's Priviledged Architecture. - Rework of the RISC-V MSI driver This moves the driver over to the generic MSI library and solves the affinity problem of unmaskable PCI/MSI controllers. Unmaskable PCI/MSI controllers are prone to lose interrupts when the MSI message is updated to change the affinity because the message write consists of three 32-bit subsequent writes, which update address and data. As these writes are non-atomic versus the device raising an interrupt, the device can observe a half written update and issue an interrupt on the wrong vector. This is mitiated by a carefully orchestrated step by step update and the observation of an eventually pending interrupt on the CPU which issues the update. The algorithm follows the well established method of the X86 MSI driver. - A new driver for the RISC-V Sophgo SG2042 MSI controller - Overhaul of the Renesas RZQ2L driver Simplification of the probe function by using devm_*() mechanisms, which avoid the endless list of error prone gotos in the failure paths. - Expand the Renesas RZV2H driver to support RZ/G3E SoCs - A workaround for Rockchip 3568002 erratum in the GIC-V3 driver to ensure that the addressing is limited to the lower 32-bit of the physical address space. - Add support for the Allwinner AS23 NMI controller - Expand the IMX irqsteer driver to handle up to 960 input interrupts - The usual small updates, cleanups and device tree changes * tag 'irq-drivers-2025-03-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (40 commits) irqchip/imx-irqsteer: Support up to 960 input interrupts irqchip/sunxi-nmi: Support Allwinner A523 NMI controller dt-bindings: irq: sun7i-nmi: Document the Allwinner A523 NMI controller irqchip/davinci-cp-intc: Remove public header irqchip/renesas-rzv2h: Add RZ/G3E support irqchip/renesas-rzv2h: Update macros ICU_TSSR_TSSEL_{MASK,PREP} irqchip/renesas-rzv2h: Update TSSR_TIEN macro irqchip/renesas-rzv2h: Add field_width to struct rzv2h_hw_info irqchip/renesas-rzv2h: Add max_tssel to struct rzv2h_hw_info irqchip/renesas-rzv2h: Add struct rzv2h_hw_info with t_offs variable irqchip/renesas-rzv2h: Use devm_pm_runtime_enable() irqchip/renesas-rzv2h: Use devm_reset_control_get_exclusive_deasserted() irqchip/renesas-rzv2h: Simplify rzv2h_icu_init() irqchip/renesas-rzv2h: Drop irqchip from struct rzv2h_icu_priv irqchip/renesas-rzv2h: Fix wrong variable usage in rzv2h_tint_set_type() dt-bindings: interrupt-controller: renesas,rzv2h-icu: Document RZ/G3E SoC riscv: sophgo: dts: Add msi controller for SG2042 irqchip: Add the Sophgo SG2042 MSI interrupt controller dt-bindings: interrupt-controller: Add Sophgo SG2042 MSI arm64: dts: rockchip: rk356x: Move PCIe MSI to use GIC ITS instead of MBI ...
