| * | KVM: PPC: Book3S HV: Tracepoints for KVM HV guest interactions | Suresh E. Warrier | 2014-12-17 | 1 | -24/+1 |
| | | | | | | | | | | | | This patch adds trace points in the guest entry and exit code and also for exceptions handled by the host in kernel mode - hypercalls and page faults. The new events are added to /sys/kernel/debug/tracing/events under a new subsystem called kvm_hv.

| * | KVM: PPC: Make shared struct aka magic page guest endian | Alexander Graf | 2014-05-30 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | The shared (magic) page is a data structure that contains often used supervisor privileged SPRs accessible via memory to the user to reduce the number of exits we have to take to read/write them. When we actually share this structure with the guest we have to maintain it in guest endianness, because some of the patch tricks only work with native endian load/store operations. Since we only share the structure with either host or guest in little endian on book3s_64 pr mode, we don't have to worry about booke or book3s hv. For booke, the shared struct stays big endian. For book3s_64 hv we maintain the struct in host native endian, since it never gets shared with the guest. For book3s_64 pr we introduce a variable that tells us which endianness the shared struct is in and route every access to it through helper inline functions that evaluate this variable.

| * | kvm: powerpc: book3s: pr: move PR related tracepoints to a separate header | Aneesh Kumar K.V | 2013-10-17 | 1 | -0/+297 |
| This patch moves PR related tracepoints to a separate header. This enables in converting PR to a kernel module which will be done in later patches Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de> | |||||
