KVM: SVM: Intercept the 'invd' and 'wbinvd' instructions

2007-12-14T17:50:55Z

patch cf5a94d1331b411b84414c13e43f578260942d6b in mainline. 'invd' can destroy host data, and 'wbinvd' allows the guest to induce long (milliseconds) latencies. Noted by Ben Serebrin. Signed-off-by: Avi Kivity Signed-off-by: Greg Kroah-Hartman

KVM: SVM: Reliably detect if SVM was disabled by BIOS

2007-07-16T09:05:49Z

This patch adds an implementation to the svm is_disabled function to detect reliably if the BIOS disabled the SVM feature in the CPU. This fixes the issues with kernel panics when loading the kvm-amd module on machines where SVM is available but disabled. Signed-off-by: Joerg Roedel Signed-off-by: Avi Kivity

KVM: Initialize the BSP bit in the APIC_BASE msr correctly

KVM: Flush remote tlbs when reducing shadow pte permissions

2007-07-16T09:05:46Z

When a vcpu causes a shadow tlb entry to have reduced permissions, it must also clear the tlb on remote vcpus. We do that by: - setting a bit on the vcpu that requests a tlb flush before the next entry - if the vcpu is currently executing, we send an ipi to make sure it exits before we continue Signed-off-by: Avi Kivity

KVM: Move duplicate halt handling code into kvm_main.c

KVM: Lazy guest cr3 switching

2007-07-16T09:05:45Z

Switch guest paging context may require us to allocate memory, which might fail. Instead of wiring up error paths everywhere, make context switching lazy and actually do the switch before the next guest entry, where we can return an error if allocation fails. Signed-off-by: Avi Kivity

KVM: SVM: Allow direct guest access to PC debug port

2007-07-16T09:05:37Z

The PC debug port is used for IO delay and does not require emulation. Signed-off-by: Anthony Liguori Signed-off-by: Avi Kivity

Detach sched.h from mm.h

2007-05-21T16:18:19Z

First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).
