QEMU dies on any attempt to load a Linux kernel module when using a 9P rootfs
I booted a Gentoo Linux installation in QEMU with a 9P rootfs as follows: sudo qemu-kvm -cpu host -m 1024 -kernel /mnt/test/usr/src/linux-3.13-rc1/arch/x86/boot/bzImage -append 'root=/dev/root rootfstype=9p rootflags=trans=virtio,version=9p2000.L ro console=ttyS0' -serial stdio -fsdev local,id=root,path=/mnt/test,security_model=none -device virtio-9p-pci,fsdev=root,mount_tag=/dev/root The system boots fine, but attempting to load any module will fail: localhost ~ # modprobe crc32 qemu-system-x86_64: virtio: trying to map MMIO memory The behavior is consistent no matter what combination of things that I try. So far, I have tried Linux 3.10.7-gentoo (Gentoo patchset) and Linux 3.13-rc1. I have tried QEMU 1.4.2, QEMU 1.6.1 and QEMU HEAD. I have also tried booting without KVM, but the behavior is the same: sudo qemu-kvm --no-kvm -m 1024 -kernel /mnt/test/usr/src/linux-3.13-rc1/arch/x86/boot/bzImage -append 'root=/dev/root rootfstype=9p rootflags=trans=virtio,version=9p2000.L ro console=ttyS0' -serial stdio -fsdev local,id=root,path=/mnt/test,security_model=none -device virtio-9p-pci,fsdev=root,mount_tag=/dev/root Here is a backtrace of QEMU itself that I obtained using gdb: Breakpoint 1, virtqueue_map_sg (sg=0x7f695b797b98, addr=0x7f695b793b98, num_sg=3, is_write=1) at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/hw/virtio/virtio.c:434 434 error_report("virtio: trying to map MMIO memory"); (gdb) bt #0 virtqueue_map_sg (sg=0x7f695b797b98, addr=0x7f695b793b98, num_sg=3, is_write=1) at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/hw/virtio/virtio.c:434 #1 0x00000000006eb666 in virtqueue_pop (vq=0x1b23740, elem=0x7f695b793b88) at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/hw/virtio/virtio.c:500 #2 0x00000000004a74ee in handle_9p_output (vdev=0x7f695b1fd910, vq=0x1b23740) at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/hw/9pfs/virtio-9p.c:3254 #3 0x00000000006ec4b5 in virtio_queue_notify_vq (vq=0x1b23740) at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/hw/virtio/virtio.c:720 #4 0x00000000006edf65 in virtio_queue_host_notifier_read (n=0x1b23790) at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/hw/virtio/virtio.c:1116 #5 0x00000000005d3c9c in qemu_iohandler_poll (pollfds=0x1aae200, ret=1) at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/iohandler.c:143 #6 0x00000000005d4702 in main_loop_wait (nonblocking=0) at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/main-loop.c:484 #7 0x000000000066c583 in main_loop () at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/vl.c:2014 #8 0x00000000006730d1 in main (argc=17, argv=0x7fffa93167c8, envp=0x7fffa9316858) at /usr/src/debug/app-emulation/qemu-9999/qemu-9999/vl.c:4366 I spoke with Alexander Graf about this in IRC. He suggested that the guest is passing QEMU a bad address and gave me a small patch to use to get the VM to stop when this happens so that I could attach gdb and poke around. Sadly, I was on my way out to dinner when he gave that to me and I subsequently lost the patch to the Debian's paste bin's garbage collection. I have tried debugging without it by booting qemu with `-s -S`, setting break points for the kernel module initialization routines and running the system, but the breakpoints are not triggering. If I could get another copy of the patch that Alexander gave me, I would be able to move forward. Unfortunately, he is not on IRC right now. I cannot debug any further with my current knowledge, so I am sending what I know so far to the relevant mailing lists. It would be greatly appreciated if someone would point me in the right direction (or even better, send me a patch to fix what is wrong). P.S. As a side note, there appears to be regression between 3.10.7 and 3.13-rc1. In specific, the rootfs will fail to mount unless I use mount_tag=/dev/root and pass root=/dev/root. With 3.10.7, I could use an arbitrary name. -------------- next part -------------- # # Automatically generated file; DO NOT EDIT. # Linux/x86 3.13.0-rc1 Kernel Configuration # CONFIG_64BIT=y CONFIG_X86_64=y CONFIG_X86=y CONFIG_INSTRUCTION_DECODER=y CONFIG_OUTPUT_FORMAT="elf64-x86-64" CONFIG_ARCH_DEFCONFIG="arch/x86/configs/x86_64_defconfig" CONFIG_LOCKDEP_SUPPORT=y CONFIG_STACKTRACE_SUPPORT=y CONFIG_HAVE_LATENCYTOP_SUPPORT=y CONFIG_MMU=y CONFIG_NEED_DMA_MAP_STATE=y CONFIG_NEED_SG_DMA_LENGTH=y CONFIG_GENERIC_ISA_DMA=y CONFIG_GENERIC_BUG=y CONFIG_GENERIC_BUG_RELATIVE_POINTERS=y CONFIG_GENERIC_HWEIGHT=y CONFIG_ARCH_MAY_HAVE_PC_FDC=y CONFIG_RWSEM_XCHGADD_ALGORITHM=y CONFIG_GENERIC_CALIBRATE_DELAY=y CONFIG_ARCH_HAS_CPU_RELAX=y CONFIG_ARCH_HAS_CACHE_LINE_SIZE=y CONFIG_ARCH_HAS_CPU_AUTOPROBE=y CONFIG_HAVE_SETUP_PER_CPU_AREA=y CONFIG_NEED_PER_CPU_EMBED_FIRST_CHUNK=y CONFIG_NEED_PER_CPU_PAGE_FIRST_CHUNK=y CONFIG_ARCH_HIBERNATION_POSSIBLE=y CONFIG_ARCH_SUSPEND_POSSIBLE=y CONFIG_ARCH_WANT_HUGE_PMD_SHARE=y CONFIG_ARCH_WANT_GENERAL_HUGETLB=y CONFIG_ZONE_DMA32=y CONFIG_AUDIT_ARCH=y CONFIG_ARCH_SUPPORTS_OPTIMIZED_INLINING=y CONFIG_ARCH_SUPPORTS_DEBUG_PAGEALLOC=y CONFIG_X86_64_SMP=y CONFIG_X86_HT=y CONFIG_ARCH_HWEIGHT_CFLAGS="-fcall-saved-rdi -fcall-saved-rsi -fcall-saved-rdx -fcall-saved-rcx -fcall-saved-r8 -fcall-saved-r9 -fcall-saved-r10 -fcall-saved-r11" CONFIG_ARCH_SUPPORTS_UPROBES=y CONFIG_DEFCONFIG_LIST="/lib/modules/$UNAME_RELEASE/.config" CONFIG_IRQ_WORK=y CONFIG_BUILDTIME_EXTABLE_SORT=y #

QEMU dies on any attempt to load a Linux kernel module when using a 9P rootfs
I figured out the problem. There is zerocopy IO is being done via DMA to a buffer allocated with valloc(). Right now, I am running a hack-fix locally so I can get some other stuff done first.

I think I started this kernel half way through the 3.16 merge window. The last non-cherry-picked patch I have is: commit 6d87c225f5d82d29243dc124f1ffcbb0e14ec358 Merge: 338c09a 22001f6 Author: Linus Torvalds <torvalds at linux-foundation.org> Date: Thu Jun 12 23:06:23 2014 -0700 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client So I do have the change you pointed out. Nevertheless, I'll reconfirm with the latest torvalds/master. Thanks, Christopher -- Employee of Qualcomm Innovation Center, Inc.

Thanks for pointing me in that direction.
