[Xen-devel] Console is not working with 2.6.38.4 Dom0 and Xen unstable
Hi, I''m building my development with Debian Squeeze, Xen unstable and the latest 2.6.38.4 kernel. According to Xen wiki page, graphic subsystem is not working with 2.6.38 [1], so I disable GDM. I also set up various Xen and Linux debug options, now that my grub entry looks like: --- start of grub config --- multiboot /boot/xen-4.gz com1=115200,8n1 console=com1,vga sync_console console_to_ring loglvl=all guest_loglvl=all noreboot lapic=debug apic_verbosity=debug apic=debug iommu=off module /boot/vmlinuz-2.6.38.4-liuw+ console=hvc0,vga earlyprintk=xen nomodeset initcall_debug debug loglevel=10 root=UUID=fd49322b-830f-44d2-8bdf-de5c355bb159 ro quiet --- end of grub config --- Another thing I do is setup a serial tty in /etc/inittab, which looks like: --- start of inittab --- s0:2345:respawn:/sbin/getty 115200 ttyS0 --- end of inittab --- After Xen relinquishes the VGA console, the screen goes black. Serial line has some output, but no login prompt is showed. However, I can login with SSH. Everything works fine. So it seems that the VGA console and serial console are not working properly. Any suggestions?

Re: [Xen-devel] Console is not working with 2.6.38.4 Dom0 and Xen unstable
I test with various command line options, along with Konrad''s [1] and Jeremy''s [2] kernel. It''s still blank. Konrad''s kernel is 2.6.39-rc4, runs well on bare metal, blank screen on Xen unstable. Jeremy''s kernel is 2.6.32.39, assertion fails with boot_cpu_has(X86_FEATURE_TSC_RELIABLE) when booting on Xen unstable. I also skim hvc_xen.c, the Dom0 console operations are straight forward -- they are just wrapper of console IO hypercall.

Re: [Xen-devel] Console is not working with 2.6.38.4 Dom0 and Xen unstable
Finally, I manage to get a working serial console with much tuning. To wrap it up, getty for hvc0 and correct flow-control option are necessary. But I''m still interested in a working VGA console. I''ll get to that later. :) Thank you for your help, Pasi. -- Best regards Wei Liu Twitter: @iliuw Site: http://liuw.name _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Firstly you don''t give multiple consoles separated with "," you need to give multiple "console=FOO" (with only the last one becoming /dev/console, I think). In Linux console= syntax a "," separates a console name from its options. Secondly the VGA console is called "tty<n>" in Linux console= speak and not "vga" (this differs from Xen and Linux''s earlyprintk=). Documentation/kernel-parameters.txt in the kernel source has a bit more info on the syntax, so do things like Documentation/serial-console.txt.

I use Debian package 2.6.32-5-xen-amd64 with Xen-unstable, it panics with boot_cpu_has(X86_FEATURE_TSC_RELIABLE), but the VGA console is working, I can see information printing out. Then I copy the config-2.6.32-5-xen-amd64 to my 2.6.39 kernel directory and `make oldconfig`, which I expect it will produces a kernel that will work. However, it did not turn out as expected. It''s still blank. I diff''ed these two configs, the differences seem irrelavent.

Did you compile with the CONFIG_DRM_I915_KMS=y Also you might want to run with ''drm.debug=255'' just to see where it stops working correctly. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

After I set CONFIG_DRM_I915_KMS=y and added drm.debug=255 to the command line. The kernel hangs with "[drm:i915_get_vblank_timestamp], crtc 0 is disabled", repeating forever. If I don''t add drm.debug=255, it boots smoothly. And the VGA console shows up.
