x86: Make xen use the paravirt clocksource structs and functions

2008-06-24T18:02:32Z

This patch updates the xen guest to use the pvclock structs and helper functions. Signed-off-by: Gerd Hoffmann Acked-by: Jeremy Fitzhardinge Signed-off-by: Avi Kivity

xen: add balloon driver

2008-04-24T21:57:33Z

The balloon driver allows memory to be dynamically added or removed from the domain, in order to allow host memory to be balanced between multiple domains. This patch introduces the Xen balloon driver, though it currently only allows a domain to be shrunk from its initial size (and re-grown back to that size). A later patch will add the ability to grow a domain beyond its initial size. Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

xen pvfb: Para-virtual framebuffer, keyboard and pointer driver

2008-04-24T21:57:33Z

This is a pair of Xen para-virtual frontend device drivers: drivers/video/xen-fbfront.c provides a framebuffer, and drivers/input/xen-kbdfront provides keyboard and mouse. The backends run in dom0 user space. The two drivers are not in two separate patches, because the intermediate step (one driver, not the other) is somewhat problematic: the backend in dom0 needs both drivers, and will refuse to complete device initialization unless they're both present.

xen: Make xen-blkfront write its protocol ABI to xenstore

2008-04-24T21:57:32Z

Frontends are expected to write their protocol ABI to xenstore. Since the protocol ABI defaults to the backend's native ABI, things work fine without that as long as the frontend's native ABI is identical to the backend's native ABI. This is not the case for xen-blkfront running 32-on-64, because its ABI differs between 32 and 64 bit, and thus needs this fix.

xen: import arch generic part of xencomm

2008-04-24T21:57:32Z

On xen/ia64 and xen/powerpc hypercall arguments are passed by pseudo physical address (guest physical address) so that it's necessary to convert from virtual address into pseudo physical address. The frame work is called xencomm. Import arch generic part of xencomm. Signed-off-by: Isaku Yamahata Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

xen: add missing definitions in include/xen/interface/vcpu.h which ia64/xen needs

2008-04-24T21:57:32Z

Add xen handles realted definitions for xen vcpu which ia64/xen needs. Pointer argumsnts for ia64/xen hypercall are passed in pseudo physical address (guest physical address) so that it is required to convert guest kernel virtual address into pseudo physical address. The xen guest handle represents such arguments. Signed-off-by: Isaku Yamahata Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

xen: add missing definitions for xen grant table which ia64/xen needs

2008-04-24T21:57:32Z

Add xen handles realted definitions for grant table which ia64/xen needs. Pointer argumsnts for ia64/xen hypercall are passed in pseudo physical address (guest physical address) so that it is required to convert guest kernel virtual address into pseudo physical address right before issuing hypercall. The xen guest handle represents such arguments. Define necessary handles and helper functions.

xen: definitions which ia64/xen needs

2008-04-24T21:57:32Z

Add xen VIRQ numbers defined for arch specific use. ia64/xen domU uses VIRQ_ARCH_0 for virtual itc timer. Although all those constants aren't used yet by ia64 at this moment, add all arch specific VIRQ numbers.

xen: definisions which ia64 needs

2008-04-24T21:57:32Z

Add xen hypercall numbers defined for arch specific use. ia64/xen domU uses __HYPERVISOR_arch_1 to manipulate paravirtualized IOSAPIC. Although all those constants aren't used yet by IA64 at this moment, add all arch specific hypercall numbers.
