Ok. so I will then shift to using system tap, Are the timestamps generated for events compatible with the ftrace timestamps? so that I can still merge the traces using TSC_OFFSET. Thanks, On Tue, Aug 16, 2016 at 8:05 PM, Daniel P. Berrange wrote: > On Tue, Aug 16, 2016 at

[Qemu-devel] [PATCH v5] fpu: add mechanism to check for invalid long double formats

All operations that take a floatx80 as an operand need to have their inputs checked for malformed encodings. In all of these cases, use the function floatx80_invalid_encoding to perform the check. If an invalid operand is found, raise an invalid operation exception, and then return either NaN (for

I explicitly left the check off the comparison operations because I misread the NaN check as something equivalent to the check I would be adding. I'll add it shortly. With regards to adding int32_indefinite, etc constants, I think I'll leave it as is -- I'd prefer to have *what* happens clear

[Qemu-devel] [PATCH for-2.8 0/2] vhost-vsock: add vhost-vsock device

This patch series adds -device vhost-vsock,guest-cid= to QEMU. The vsock device is a host-guest communications device comparable to virtio-serial except it offers POSIX Sockets API semantics. It uses the vhost_vsock.ko Linux kernel module for AF_VSOCK socket communications. The kernel module
