I've managed to get my l4linux build to start running, but it doesn't seem to get far: l4linux | libio: Warning: Finding 'icu' in system bus failed with 'No such object found' 4linux | PH 0 (t: 1) offs=00001000 vaddr=00400000 vend=005d1000 l4linux | phys=00400000 ephys=005d1000 l4linux | f_sz=001d0cb8 memsz=001d1000 flgs=r-x l4linux | PH 1 (t: 1) offs=001d2000 vaddr=005d1000 vend=00d36000 l4linux | phys=005d1000 ephys=00d36000 l4linux | f_sz=006c4c10 memsz=00765000 flgs=rw- l4linux | PH 2 (t: 4) offs=0015df14 vaddr=0055cf14 vend=0055cf38 l4linux | phys=0055cf14 ephys=0055cf38 l4linux | f_sz=00000024 memsz=00000024 flgs=--- l4linux | Starting binary at 0x400000, argc=3 argv=0x80007f9c *argv=0xb1007ff4 argv0=rom/vmlinuz l4linux | External resolver is at 0xa80006e0 l4linux | ======> L4Linux 2.6 starting... <======== l4linux | Linux version 3.0.0-l4-svn23 (ribrdb@ribox.sfo.corp.google.com) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5.1) ) #10 Wed Jun 27 16:00:19 PDT 2012 l4linux | Binary name: rom/vmlinuz l4linux | Linux kernel command line (2 args): mem=200M console=ttyLv0 l4linux | Configuration checks disabled, you know what you're doing. l4linux | CPU mapping (l:p)[1]: 0:0 l4linux | Image: 00400000 - 00d36000 [9432 KiB]. l4linux | Areas: Text: 00400000 - 005d1000 [1860kB] (a bit longer) l4linux | Data: 005d1000 - 005edc60 [115kB] l4linux | Initdata: 005ef000 - 00c96000 [6812kB] l4linux | BSS: 00c96000 - 00d26000 [576kB] l4linux | gs=43 fs=43 l4linux | Device scan: l4linux | l4x_fiasco_gdt_entry_offset = 9
Then it just stops. What's happened here? Should I see more output? Or does the kernel output go somewhere else? I've compiled my kernel with an initramfs that does an "echo hello init" at the beginning of init, but I never see that.
Do I need to worry about that 'icu' 'No such object found'? I tried adding a capability to icu for l4linux, but that didn't seem to help.
Also, I'm having trouble getting my io config correct. IO prints out: io | Loading: config 'rom/l4lx-virtio.io' io | rom/l4lx-virtio.io:7.37-50: warning: could not find 'PCI/VEN_1AF4'
but then later on I see:
io | P6Device: S4__ "" io | Hw::Device[S4__] io | 0000:00:04.0: display controller [0] io | 0x1af4 0x1000 io | Red Hat, Inc Virtio network device io | IOPORT [0000000000c000-0000000000c03f 40] non-pref (32bit) (align=3f flags=4a03) io | IRQ [0000000000000b-0000000000000b 1] level high (32bit) (align=0 flags=104201)
What's up with that?
Here's my settings:
