--- Comment #9 from Андрей Кольчугин
Unfortunately, X is entirely unavailable as of framebuffer by itself is -- under _any_ working IOMMU (either under bare Linux kernel or under tboot/Linux) vesafb doesn't recognise any devices. I can't confirm this - I'm seeing vesafb working quite fine irrespective of the presence/use of an IOMMU. Are you perhaps not passing a suitable "vga=" option to the kernel (albeit iirc it's the boot loader honoring it), or a "mode=" one to the hypervisor? Hmmm... Yes, I thought that boot loader honoring it.
1) No. It doesn't in a case of multi-boot; 2) "mode=" is for Linux kernel and "vga=" is for hypervisor; 3) Xen v4.2.1 doesn't like lines a la "vga=031b"/"vga=0x31b", but "vga=gfx-1280x1024x32" works fine; 4) BOTH parameters must be present -- for hypervisor and for kernel. And it works! Framebuffer now recognised by both Linux kernel and X Window system, albeit i915 KMS should be fixed. ;) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
