* x86, hvm: Guest CPUID configuration.Keir Fraser2008-04-254-0/+562
| | | | | | | | | | | | CPUID's replies are now pre-calculated in libxc and given to the hypervisor via a new domctl. There are two parts to this feature: - We can overwrite cpuid's replies. - We can check that a vm is compatible with a host's processor.

* x86, vmx: Enable EPT (Extended PageTable) support on new Intel processors.Keir Fraser2008-04-091-25/+45
| | | | | | | | | | | | | We use the EPT page table as P2M (guest physical to machine mapping), removing the linear page table when EPT is used for the domain (see the new file p2m-ept.c). We did this by adding three operations in the p2m_domain. If VT-d is enabled, the EPT page table will be used as the VT-d page table as well (i.e. shared).

| * x86: Support loading Linux bzImage v2.08 and up.Keir Fraser2008-04-013-5/+165
| | | | | | | | | | | | | | | | | | | | The latest -mm kernel (2.6.25-rc3-mm1) contains v2.08 of the Linux bzImage format which embeds an ELF file in place of the raw payload allowing it to be extracted and used by the Xen domain builder. It is expected that this functionality will be put forward for 2.6.26. Signed-off-by : Ian Campbell <ijc@hellion.org.uk>

| * minios: Fix lost eventsKeir Fraser2008-03-181-11/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | evtchn_bind_interdomain used to clear any already pending event before binding a handler, because else the handler may be called before it is ready. That however leads to missed events, which I had to workaround for the HVM case. This changes the semantics of bind_evtchn, and thus of all the event channel binding functions (bind_virq, evtchn_alloc_unbound, evtchn_bind_interdomain) into not unmasking the event itself, hence letting the caller initialize properly before unmasking the port (e.g. record the port number in an appropriate place).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Move PAGE_SIZE and STACK_SIZE into __PAGE_SIZE and __STACK_SIZE in arch_limits.h so as to permit getting them from there without pulling all the internal Mini-OS defines. - Setup a xen-elf cross-compilation environment in stubdom/cross-root - Add a POSIX layer on top of Mini-OS by linking against the newlib C library and lwIP, and implementing the Unixish part in mini-os/lib/sys.c - Cross-compile zlib and libpci too. - Add an xs.h-compatible layer on top of Mini-OS' xenbus. - Cross-compile libxc with an additional xc_minios.c and a few things disabled. - Cross-compile ioemu with an additional block-vbd, but without sound, tpm and other details. A few hacks are needed: - Align ide and scsi buffers at least on sector size to permit direct transmission to the block backend. While we are at it, just page-align it to possibly save a segment. Also, limit the scsi buffer size because of limitations of the block paravirtualization protocol. - Allocate big tables dynamically rather that letting them go to bss: when Mini-OS gets installed in memory, bss is not lazily allocated, and doing so during Mini-OS is unnecessarily trick while we can simply use malloc. - Had to change the Mini-OS compilation somehow, so as to export Mini-OS compilation flags to the Makefiles of libxc and ioemu.
