Hi all, i've got a strange situation. I'm using the latest jailhouse branch on x86 with a linux root cell and a Bare Metal cell connected via 2 pci device (bdf e.00 and f.00). Two Ivshmem device are correctly mapped to /dev/uio0 and /dev/uio1. But if on /dev/uio0 i can correctly map registers ( offset 0, size 0x1000) and shmem (offset 0x1000, size 0x1000), for /dev/uio1 the first mapping fails with the ENODEV errno set (shmem mapping is done correctly). Parameters of mapping are the same for uio0 and uio1. Here i list a dmesg snippet of the root cell kernel: [ 302.092280] pci 0000:00:0e.0: [1af4:1110] type 00 class 0xff0000 [ 302.092622] pci 0000:00:0e.0: reg 0x10: [mem 0x00000000-0x000000ff 64bit] [ 302.092776] hpet_rtc_timer_reinit: 39 callbacks suppressed [ 302.092777] hpet1: lost 62 rtc interrupts [ 302.093025] pci 0000:00:0e.0: reg 0x20: [mem 0x00000000-0x0000001f 64bit] [ 302.093634] pci 0000:00:0e.0: BAR 0: assigned [mem 0xc0000000-0xc00000ff 64bit] [ 302.093765] pci 0000:00:0e.0: BAR 4: assigned [mem 0xc0000100-0xc000011f 64bit] [ 302.093982] virtio-pci 0000:00:0e.0: enabling device (0000 -> 0002) [ 302.094169] uio_ivshmem 0000:00:0e.0: using jailhouse mode [ 302.094625] uio_ivshmem 0000:00:0e.0: MSI-X enabled [ 302.094918] pci 0000:00:0f.0: [1af4:1110] type 00 class 0xff0000 [ 302.095259] pci 0000:00:0f.0: reg 0x10: [mem 0x00000000-0x000000ff 64bit] [ 302.095725] pci 0000:00:0f.0: reg 0x20: [mem 0x00000000-0x0000001f 64bit] [ 302.096468] pci 0000:00:0f.0: BAR 0: assigned [mem 0xc0000200-0xc00002ff 64bit] [ 302.096667] pci 0000:00:0f.0: BAR 4: assigned [mem 0xc0000120-0xc000013f 64bit] [ 302.096962] virtio-pci 0000:00:0f.0: enabling device (0000 -> 0002) [ 302.097139] uio_ivshmem 0000:00:0f.0: using jailhouse mode [ 302.097568] uio_ivshmem 0000:00:0f.0: MSI-X enabled What i'm doing wrong? I do exactly the same things on /dev/uio0 and /dev/uio1 Thanks, --Luca -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
