target-i386: yield to another VCPU on PAUSE After commit b1bbfe7 (aio / timers: On timer modification, qemu_notify or aio_notify, 2013-08-21) FreeBSD guests report a huge slowdown. The problem shows up as soon as FreeBSD turns out its periodic (~1 ms) tick, but the timers are only the trigger for a pre-existing problem. Before the offending patch, setting a timer did a timer_settime system call. After, setting the timer exits the event loop (which uses poll) and reenters it with a new deadline. This does not cause any slowdown; the difference is between one system call (timer_settime and a signal delivery (SIGALRM) before the patch, and two system calls afterwards (write to a pipe or eventfd + calling poll again when re-entering the event loop). Unfortunately, the exit/enter causes the main loop to grab the iothread lock, which in turns kicks the VCPU thread out of execution. This causes TCG to execute the next VCPU in its round-robin scheduling of VCPUS. When the second VCPU is mostly unused, FreeBSD runs a "pause" instruction in its idle loop which only burns cycles without any progress. As soon as the timer tick expires, the first VCPU runs the interrupt handler but very soon it sets it again---and QEMU then goes back doing nothing in the second VCPU. The fix is to make the pause instruction do "cpu_loop_exit".

x86: Implement SMEP and SMAP This patch implements Supervisor Mode Execution Prevention (SMEP) and Supervisor Mode Access Prevention (SMAP) for x86. The purpose of the patch, obviously, is to help kernel developers debug the support for those features. A fair bit of the code relates to the handling of CPUID features. The CPUID code probably would get greatly simplified if all the feature bit words were unified into a single vector object, but in the interest of producing a minimal patch for SMEP/SMAP, and because I had very limited time for this project, I followed the existing style. [ v2: don't change the definition of the qemu64 CPU shorthand, since that breaks loading old snapshots. Per Anthony Liguori this can be fixed once the CPU feature set is snapshot. Change the coding style slightly to conform to checkpatch.pl. ] Signed-off-by: H. Peter Anvin <hpa@linux.intel.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

x86: avoid AREG0 for FPU helpers Make FPU helpers take a parameter for CPUState instead of relying on global env. Introduce temporary wrappers for FPU load and store ops. Remove wrappers for non-AREG0 code. Don't call unconverted helpers directly. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
