2008-05-27xen: compilation fix to balloon driver for ia64 supportIsaku Yamahata1-4/+4
fix compilation error of ballon driver on ia64. extent_start member is pointer argument. On x86 pointer argument for xen hypercall is passed as virtual address. On the other hand, ia64 and ppc, pointer argument is passed in pseudo physical address. (guest physicall address.) So they must be passed as handle and convert right before issuing hypercall.

2008-05-27xen: make earlyprintk=xen work againJeremy Fitzhardinge2-0/+2
For some perverse reason, if you call add_preferred_console() it prevents setup_early_printk() from successfully enabling the boot console - unless you make it a preferred console too... Also, make xenboot console output distinct from normal console output, since it gets repeated when the console handover happens, and the duplicated output is confusing without disambiguation.

2008-05-27xen pvfb: Dynamic mode support (screen resizing)Markus Armbruster3-34/+188
The pvfb backend indicates dynamic mode support by creating node feature_resize with a non-zero value in its xenstore directory. xen-fbfront sends a resize notification event on mode change. Fully backwards compatible both ways. Framebuffer size and initial resolution can be controlled through kernel parameter xen_fbfront.video. The backend enforces a separate size limit, which it advertises in node videoram in its xenstore directory. xen-kbdfront gets the maximum screen resolution from nodes width and height in the backend's xenstore directory instead of hardcoding it. Additional goodie: support for larger framebuffers (512M on a 64-bit system with 4K pages). Changing the number of bits per pixels dynamically is not supported, yet.

2008-05-27xen: Enable console tty by default in domU if it's not a dummyMarkus Armbruster4-1/+33
Without console= arguments on the kernel command line, the first console to register becomes enabled and the preferred console (the one behind /dev/console). This is normally tty (assuming CONFIG_VT_CONSOLE is enabled, which it commonly is). This is okay as long tty is a useful console. But unless we have the PV framebuffer, and it is enabled for this domain, tty0 in domU is merely a dummy. In that case, we want the preferred console to be the Xen console hvc0, and we want it without having to fiddle with the kernel command line. Commit b8c2d3dfbc117dff26058fbac316b8acfc2cb5f7 did that for us. Since we now have the PV framebuffer, we want to enable and prefer tty again, but only when PVFB is enabled. But even then we still want to enable the Xen console as well. Problem: when tty registers, we can't yet know whether the PVFB is enabled. By the time we can know (xenstore is up), the console setup game is over. Solution: enable console tty by default, but keep hvc as the preferred console. Change the preferred console to tty when PVFB probes successfully, unless we've been given console kernel parameters.

2008-05-27x86/paravirt: add pte_flags to just get pte flagsJeremy Fitzhardinge6-9/+26
Add pte_flags() to extract the flags from a pte. This is a special case of pte_val() which is only guaranteed to return the pte's flags correctly; the page number may be corrupted or missing. The intent is to allow paravirt implementations to return pte flags without having to do any translation of the page number (most notably, Xen).

2008-05-20ipsec: Use the correct ip_local_out functionHerbert Xu2-2/+2
Because the IPsec output function xfrm_output_resume does its own dst_output call it should always call __ip_local_output instead of ip_local_output as the latter may invoke dst_output directly. Otherwise the return values from nf_hook and dst_output may clash as they both use the value 1 but for different purposes. When that clash occurs this can cause a packet to be used after it has been freed which usually leads to a crash. Because the offending value is only returned from dst_output with qdiscs such as HTB, this bug is normally not visible. Thanks to Marco Berizzi for his perseverance in tracking this down.
