* mini-os: remove per-fd evtchn limitAlex Zeffertt2012-02-091-66/+74
| | | | | | | | | | | | | This changes the minios evtchn implementation to use a list instead of an array which ahis allows it to grow as necessary to support any number of ports, only limited by Xen (NR_EVS is 1024, should be enough for now).

* lib{xc,xl}: Seed grant tables with xenstore and console grantsAlex Zeffertt2012-02-097-7/+211
| | | | | | | | | | | | | | | | | | This patch claims one reserved grant entry for the console and another for the xenstore. It modifies the builder to fill in the grant table entries for the console and the xenstore. Previous versions of this patch have been sent to xen-devel.

* xl: use json output by defaultIan Campbell2012-02-079-182/+462
| | | | | | | | | | | | | | | | | | | | | Move the sxp producing code off into a separate file. It is supported for legacy reasons and needn't be updated other than the improve compatibility with xm. libxl_domain_config is not currently generated by the IDL (adding the necessary support for Array types is on my to do list) so hand code the json generation function for now. Since this rather directly exposes a libxl data structure it's not clear what sort of forward compatibility guarantees we can make. However it seems like it should be as stable as libxl's own API (which we are looking to stabilise) (Gratuitous string.h include needed for memset in libxl_util.h) Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Acked-by: Ian Jackson <Ian.Jackson@eu.citrix.com> Committed-by: Ian Jackson <ian.jackson@eu.citrix.com>

* x86/AMD: Add support for AMD's OSVW feature in guests.Boris Ostrovsky2012-02-071-0/+1
| | | | | | | | | | | | | | | | | | In some cases guests should not provide workarounds for errata even when the physical processor is affected. For example, because of erratum 400 on family 10h processors a Linux guest will read an MSR (resulting in VMEXIT) before going to idle in order to avoid getting stuck in a non-C0 state. This is not necessary: HLT and IO instructions are intercepted and therefore there is no reason for erratum 400 workaround in the guest. This patch allows us to present a guest with certain errata as fixed, regardless of the state of actual hardware.
