From 2a55ca37350171d9b43d561528f23d4130097255 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Sat, 15 May 2021 12:08:56 -0700 Subject: vfio/pci: zap_vma_ptes() needs MMU zap_vma_ptes() is only available when CONFIG_MMU is set/enabled. Without CONFIG_MMU, vfio_pci.o has build errors, so make VFIO_PCI depend on MMU. riscv64-linux-ld: drivers/vfio/pci/vfio_pci.o: in function `vfio_pci_mmap_open': vfio_pci.c:(.text+0x1ec): undefined reference to `zap_vma_ptes' riscv64-linux-ld: drivers/vfio/pci/vfio_pci.o: in function `.L0 ': vfio_pci.c:(.text+0x165c): undefined reference to `zap_vma_ptes' Fixes: 11c4cd07ba11 ("vfio-pci: Fault mmaps to enable vma tracking") Signed-off-by: Randy Dunlap Reported-by: kernel test robot Cc: Alex Williamson Cc: Cornelia Huck Cc: kvm@vger.kernel.org Cc: Jason Gunthorpe Cc: Eric Auger Message-Id: <20210515190856.2130-1-rdunlap@infradead.org> Signed-off-by: Alex Williamson --- drivers/vfio/pci/Kconfig | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/vfio') diff --git a/drivers/vfio/pci/Kconfig b/drivers/vfio/pci/Kconfig index 53ce78d7d07b..5e2e1b9a9fd3 100644 --- a/drivers/vfio/pci/Kconfig +++ b/drivers/vfio/pci/Kconfig @@ -2,6 +2,7 @@ config VFIO_PCI tristate "VFIO support for PCI devices" depends on VFIO && PCI && EVENTFD + depends on MMU select VFIO_VIRQFD select IRQ_BYPASS_MANAGER help -- cgit v1.2.3
