Signed-off-by: Avi Kivity <avi@redhat.com>
2008-12-17kvm: qemu: Switch to new guest debug interfaceJan Kiszka3-8/+21
This patch switches both libkvm as well as the qemu pieces over to the new guest debug interface. It comes with full support for software-based breakpoints (via guest code modification), hardware-assisted breakpoints and watchpoints (x86-only so far). Breakpoint management is done inside qemu-kvm, transparently to gdbstub and also avoiding that the gdb frontend takes over. This allows for running debuggers inside the guest while guest debugging it active, because the host can cleanly tell apart host- and guest-originated breakpoint events. Yet improvable are x86 corner cases when using single-step ("forgotten" debug flags on the guest's stack). And, of course, the yet empty non-x86 helper functions have to be populated.

2008-12-14kvm: libkvm: check for slot overlap using 64-bit arithmeticAvi Kivity1-2/+2
otherwise, a slot that ends on the 4GB boundary wraps around, resulting in a false positive, and leading to an early failure when attempting to get the bios slot's dirty log (which doesn't have dirty logging enabled). fixed broken display on 32-bit userspace. Signed-off-by: Avi Kivity <avi@redhat.com>
2008-12-14kvm: qemu: Switch to KVM_CAP_USER_NMIJan Kiszka2-4/+6
Adopt to new KVM_CAP_USER_NMI interface for injecting NMIs from qemu user space. As this capability is only provided on archs actually requiring it, we can also drop a lot of empty arch stubs. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2008-11-26kvm: qemu: Cleanup user space NMI injectionJan Kiszka2-29/+4
Cleanup redundant check for an open NMI window before injecting. This will no longer be supported by the kernel, and it was broken by design anyway. This change still allows to run the user space against older kernel modules. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2008-11-02kvm: user: ppc: remove build flagsHollis Blanchard1-2/+0
Remove -m32 build flag. Although necessary when building for a 32-bit target with a biarch toolchain that defaults to 64-bit output, it naturally breaks 64-bit builds. Also remove -D__powerpc__. I'm not sure why I added that in the first place; that is automatically defined by GCC (for both 32- and 64-bit targets).

2008-10-10kvm: libkvm: change full memory logging to use the per-slot refcounting apiAvi Kivity1-7/+8
this allows full memory logging (for migration) and partial memory logging (for vga tracking) to coexist. Signed-off-by: Avi Kivity <avi@redhat.com>
2008-10-10kvm: add api to enable or disable dirty logging on a per-slot basisAvi Kivity2-0/+48
the api counts the number of requests to log a slot, so that multiple simultaneous users can be supported. when the last user disappears, dirty logging is disabled. Signed-off-by: Avi Kivity <avi@redhat.com>
2008-10-10kvm: libkvm: change the logging functions to be able to reset the log bitAvi Kivity1-8/+17
currently, the memory logging functions aren't able to clear flags, and they don't maintain the slot flags field correctly. Fix by passing a mask which indicates which bits are to be set or reset. Signed-off-by: Avi Kivity <avi@redhat.com>

2008-10-01kvm: qemu: Enable NMI support for user space irqchipJan Kiszka2-0/+54
Make use of the new KVM_NMI IOCTL to push NMIs into the KVM guest if the user space APIC emulation or some other source raised them. In order to use the 'nmi' monitor command which asynchroniously injects NMIs for the given CPU, a new service called kvm_inject_interrupt is required. This will invoke cpu_interrupt on the target VCPU, working around the fact that the QEMU service is not thread-safe.

2008-09-24kvm: libkvm: substitute is_allocated_mem with more general is_containing_regionGlauber Costa2-24/+14
is_allocated_mem is a function that checks if every relevant aspect of the memory slot match (start and size).

2008-09-24kvm: libkvm: do not use mem_hole anymore.Glauber Costa2-69/+2
memory holes are totally evil. Right now they work for some basic tests, but had never been stressed enough. Using memory holes leaves open questions like: * what happens if a area being registered span two slots? * what happens if there is already data in the slots? also, the code behaves badly if the piece to be removed lies in the boundaries of the current slot. Luckily, we don't really need it. Remove it, and make sure we never hit it. Signed-off-by: Glauber Costa <glommer@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
