From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- arch/powerpc/sysdev/ipic.h | 56 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 arch/powerpc/sysdev/ipic.h (limited to 'arch/powerpc/sysdev/ipic.h') diff --git a/arch/powerpc/sysdev/ipic.h b/arch/powerpc/sysdev/ipic.h new file mode 100644 index 000000000..45ab61406 --- /dev/null +++ b/arch/powerpc/sysdev/ipic.h @@ -0,0 +1,56 @@ +/* SPDX-License-Identifier: GPL-2.0-or-later */ +/* + * IPIC private definitions and structure. + * + * Maintainer: Kumar Gala + * + * Copyright 2005 Freescale Semiconductor, Inc + */ +#ifndef __IPIC_H__ +#define __IPIC_H__ + +#include + +#define NR_IPIC_INTS 128 + +/* External IRQS */ +#define IPIC_IRQ_EXT0 48 +#define IPIC_IRQ_EXT1 17 +#define IPIC_IRQ_EXT7 23 + +/* Default Priority Registers */ +#define IPIC_PRIORITY_DEFAULT 0x05309770 + +/* System Global Interrupt Configuration Register */ +#define SICFR_IPSA 0x00010000 +#define SICFR_IPSB 0x00020000 +#define SICFR_IPSC 0x00040000 +#define SICFR_IPSD 0x00080000 +#define SICFR_MPSA 0x00200000 +#define SICFR_MPSB 0x00400000 + +/* System External Interrupt Mask Register */ +#define SEMSR_SIRQ0 0x00008000 + +/* System Error Control Register */ +#define SERCR_MCPR 0x00000001 + +struct ipic { + volatile u32 __iomem *regs; + + /* The remapper for this IPIC */ + struct irq_domain *irqhost; +}; + +struct ipic_info { + u8 ack; /* pending register offset from base if the irq + supports ack operation */ + u8 mask; /* mask register offset from base */ + u8 prio; /* priority register offset from base */ + u8 force; /* force register offset from base */ + u8 bit; /* register bit position (as per doc) + bit mask = 1 << (31 - bit) */ + u8 prio_mask; /* priority mask value */ +}; + +#endif /* __IPIC_H__ */ -- cgit v1.3.1
