  "message": "Fix IO performance regression in sparc\n\nReplace signalfd with signal handler/pipe.  There is no way to interrupt\nthe CPU execution loop when a file descriptor becomes readable.  This\nresults in a large performance regression in sparc emulation during\nbootup.\n   \nThis patch switches us to signal handler/pipe which was originally\nsuggested by Ian Jackson.  The signal handler lets us interrupt the\nCPU emulation loop while the write to a pipe lets us avoid the\nselect/signal race condition.\n    \nSigned-off-by: Anthony Liguori \u003caliguori@us.ibm.com\u003e\n\n\n\ngit-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5451 c046a42c-6fe2-441c-8c8c-71466251a162\n",
