| 2024-08-23 | irqchip/loongarch-avec: Add AVEC irqchip support | Tianyang Zhang | |
| Introduce the advanced extended interrupt controllers (AVECINTC). This feature will allow each core to have 256 independent interrupt vectors and MSI interrupts can be independently routed to any vector on any CPU. The whole topology of irqchips in LoongArch machines looks like this if AVECINTC is supported: +-----+ +-----------------------+ +-------+ | IPI | --> | CPUINTC | <-- | Timer | +-----+ +-----------------------+ +-------+ ^ ^ ^ | | | +---------+ +----------+ +---------+ +-------+ | EIOINTC | | AVECINTC | | LIOINTC | <-- | UARTs | +---------+ +----------+ +---------+ +-------+ ^ ^ | | +---------+ +---------+ | PCH-PIC | | PCH-MSI | +---------+ +---------+ ^ ^ ^ | | | +---------+ +---------+ +---------+ | Devices | | PCH-LPC | | Devices | +---------+ +---------+ +---------+ ^ | +---------+ | Devices | +---------+ Co-developed-by: Jianmin Lv <lvjianmin@loongson.cn> Signed-off-by: Jianmin Lv <lvjianmin@loongson.cn> Co-developed-by: Liupu Wang <wangliupu@loongson.cn> Signed-off-by: Liupu Wang <wangliupu@loongson.cn> Co-developed-by: Huacai Chen <chenhuacai@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> Signed-off-by: Tianyang Zhang <zhangtianyang@loongson.cn> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/all/20240823104337.25577-2-zhangtianyang@loongson.cn | |||
| 2024-08-23 | LoongArch: Move irqchip function prototypes to irq-loongson.h | Huacai Chen | |
| Some irqchip functions are only for internal use by irqchip drivers, so move their prototypes from asm/irq.h to drivers/irqchip/irq-loongson.h. All related driver files include the new irq-loongson.h.
