From 35e0cd774af8976533deca9e47053a80db5617a9 Mon Sep 17 00:00:00 2001 From: Baoquan He Date: Fri, 7 Jul 2023 21:58:50 +0800 Subject: irqchip/al-fic: make AL_FIC depend on HAS_IOMEM On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. Here let AL_FIC depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset: ------ ld: drivers/irqchip/irq-al-fic.o: in function `al_fic_init_dt': irq-al-fic.c:(.init.text+0x76): undefined reference to `of_iomap' ld: irq-al-fic.c:(.init.text+0x4ce): undefined reference to `iounmap' ------ Link: https://lkml.kernel.org/r/20230707135852.24292-7-bhe@redhat.com Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202306211329.ticOJCSv-lkp@intel.com/ Signed-off-by: Baoquan He Cc: Thomas Gleixner Cc: Marc Zyngier Signed-off-by: Andrew Morton --- drivers/irqchip/Kconfig | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/irqchip/Kconfig') diff --git a/drivers/irqchip/Kconfig b/drivers/irqchip/Kconfig index 09e422da482f..4b9036c6d45b 100644 --- a/drivers/irqchip/Kconfig +++ b/drivers/irqchip/Kconfig @@ -89,6 +89,7 @@ config ALPINE_MSI config AL_FIC bool "Amazon's Annapurna Labs Fabric Interrupt Controller" depends on OF + depends on HAS_IOMEM select GENERIC_IRQ_CHIP select IRQ_DOMAIN help -- cgit
