2016-06-06hw/ptimer: Perform counter wrap around if timer already expiredDmitry Osipenko
ptimer_get_count() might be called while QEMU timer already been expired. In that case ptimer would return counter = 0, which might be undesirable in case of polled timer. Do counter wrap around for periodic timer to keep it distributed. In order to achieve more accurate emulation behaviour of certain hardware, don't perform wrap around when in icount mode and return counter = 0 in that case (that doesn't affect polled counter distribution).

2016-06-06hw/ptimer: Fix issues caused by the adjusted timer limit valueDmitry Osipenko
Multiple issues here related to the timer with a adjusted .limit value: 1) ptimer_get_count() returns incorrect counter value for the disabled timer after loading the counter with a small value, because adjusted limit value is used instead of the original. For instance: 1) ptimer_stop(t) 2) ptimer_set_period(t, 1) 3) ptimer_set_limit(t, 0, 1) 4) ptimer_get_count(t) <-- would return 10000 instead of 0 2) ptimer_get_count() might return incorrect value for the timer running with a adjusted limit value. For instance: 1) ptimer_stop(t) 2) ptimer_set_period(t, 1) 3) ptimer_set_limit(t, 10, 1) 4) ptimer_run(t) 5) ptimer_get_count(t) <-- might return value > 10 3) Neither ptimer_set_period() nor ptimer_set_freq() are adjusting the limit value, so it is still possible to make timer timeout value arbitrary small. For instance: 1) ptimer_set_period(t, 10000) 2) ptimer_set_limit(t, 1, 0) 3) ptimer_set_period(t, 1) <-- bypass limit correction Fix all of the above issues by adjusting timer period instead of the limit. Perform the adjustment for periodic timer only. Use the delta value instead of the limit to make decision whether adjustment is required, as limit could be altered while timer is running, resulting in incorrect value returned by ptimer_get_count.

On the TODO list, we also have : - improve and harden the state machine. - bus recovery support (used by the Linux driver). - transfer mode state machine bits. this is not strictly necessary as it is mostly used for debug.

This is wrong in several ways: * IL doesn't indicate Thumb-vs-ARM, it indicates instruction length (which may be 16 or 32 for Thumb and is always 32 for ARM) * not every syndrome format uses IL like this -- for some IL is always set, and for some it is always clear * the code is changing esr_el[new_el] even for interrupt entry, which is not supposed to modify ESR_ELx at all Delete the code, and instead rely on the syndrome value in env->exception.syndrome having already been set up with the correct value of IL.

Add support for generating the ISS (Instruction Specific Syndrome) for Data Abort exceptions taken from AArch64.

2016-06-06vmsvga: move fifo sanity checks to vmsvga_fifo_lengthGerd Hoffmann
Sanity checks are applied when the fifo is enabled by the guest (SVGA_REG_CONFIG_DONE write). Which doesn't help much if the guest changes the fifo registers afterwards. Move the checks to vmsvga_fifo_length so they are done each time qemu is about to read from the fifo.

2016-06-03e1000e: Fix build with ust trace backendDmitry Fleytman
ust trace backend has limitation of maximum 10 arguments per event. Traces with more arguments cannot be compiled for this backend. Trace e1000e_rx_rss_ip6 introduced by previous commits has 11 arguments and fails to compile with ust trace backend. This patch fixes the problem by splitting this tracepoint into two successive tracepoints with smaller number of arguments. For more information see comment regarding TP_ARGS in lttng/tracepoint.h: /* * TP_ARGS takes tuples of type, argument separated by a comma. * It can take up to 10 tuples (which means that less than 10 tuples is * fine too). * Each tuple is also separated by a comma. */ Build log generated by this problem: In file included from ./trace/generated-tracers.h:9:0, from /home/travis/build/qemu/qemu/include/trace.h:4, from util/oslib-posix.c:36: ./trace/generated-ust-provider.h:16556:3: error: unknown type name ‘_TP_EXPROTO_Bool’ In file included from /home/travis/build/qemu/qemu/include/trace.h:4:0, from util/oslib-posix.c:36: ./trace/generated-tracers.h: In function ‘trace_e1000e_rx_rss_ip6’: ./trace/generated-tracers.h:8379:431: error: expected string literal before ‘_SDT_ASM_OPERANDS_ipv6_enabled’ ./trace/generated-tracers.h:8379:431: error: implicit declaration of function ‘__tracepoint_cb_qemu___e1000e_rx_rss_ip6’ [-Werror=implicit-function-declaration] ./trace/generated-tracers.h:8379:431: error: nested extern declaration of ‘__tracepoint_cb_qemu___e1000e_rx_rss_ip6’ [-Werror=nested-externs] cc1: all warnings being treated as errors make: *** [util/oslib-posix.o] Error 1 make: *** Waiting for unfinished jobs....

2016-06-03audio: pa: Set volume of recording stream instead of recording devicePeter Krempa
Since pulseaudio 1.0 it's possible to set the individual stream volume rather than setting the device volume. With this, setting hardware mixer of a emulated sound card doesn't mess up the volume configuration of the host. A side effect is that this limits compatible pulseaudio version to 1.0 which was released on 2011-09-27.

2016-06-03virtio-gpu: fix scanout rectanglesGerd Hoffmann
Commit "ca58b45 ui/virtio-gpu: add and use qemu_create_displaysurface_pixman" breaks scanouts which use a region of the underlying resource only. So, we need another way to handle the underlying issue. Lets create a new pixman image, grab a reference on the pixman providing the underlying storage, hook up a destroy callback which releases the reference. That way regions work again and releasing the backing storage should still be impossible thanks to the extra reference we are holding.
