2012-09-10Add ability to force enable/disable of tools buildDaniel P. Berrange1-6/+15
The qemu-img, qemu-nbd and qemu-io tools are built conditionally based on whether any softmmu target is enabled. These are useful self-contained tools which can be used in many other scenarios. Add new --enable-tools/--disable-tools args to configure to allow the user to explicitly turn on / off their build. The default behaviour is now to build these tools are all times, regardless of whether any softmmu target is enabled Signed-off-by: Daniel P.

2012-09-10RTC: Get and set time without going through s->current_tmPaolo Bonzini1-16/+22
This patch makes rtc_set_time and rtc_set_cmos work without reading s->current_tm. In the case of rtc_set_time I introduce a new function that retrieves the time and stores into a given struct tm (not hard-coded to s->current_tm). In the case of rtc_set_cmos, the current time is similarly taken from a struct tm rather than s->current_tm.

2012-09-10RTC: Do not fire timer periodically to catch next alarmPaolo Bonzini1-14/+103

2012-09-10RTC: Update the RTC clock only when reading itYang Zhang1-135/+194
Calculate guest RTC based on the time of the last update, instead of using timers. The formula is (base_rtc + guest_time_now - guest_time_last_update + offset) Base_rtc is the RTC value when the RTC was last updated. Guest_time_now is the guest time when the access happens. Guest_time_last_update was the guest time when the RTC was last updated. Offset is used when divider reset happens or the set bit is toggled. The timer is kept in order to signal interrupts, but it only needs to run when either UF or AF is cleared. When the bits are both set, the timer does not run. UIP is now synthesized when reading register A. If the timer is not set, or if there is more than one second before it (as is the case at the end of this series), the leading edge of UIP is computed and the rising edge occurs 220us later. If the update timer occurs within one second, however, the rising edge of the AF and UF bits should coincide withe the falling edge of UIP. We do not know exactly when this will happen because there could be delays in the servicing of the timer. Hence, in this case reading register A only computes for the rising edge of UIP, and latches the bit until the timer is fired and clears it.

Commit 7b93fadf3a38d1ed65ea5536a52efc2772c6e3b8 "Add basic version of bridge helper" put the bridge helper executable into a fixed ${prefix}/libexec/ location, instead of using ${libexecdir} for this. At the same time, --libexecdir is being happily ignored by ./configure. Even more, the same patch sets unused $libexecdir variable in the generated config-host.mak, and uses fixed string (\${prefix}/libexecdir) for the bridge helper binary. Fix this braindamage by introducing $libexecdir variable, using it for the bridge helper binary, and recognizing --libexecdir. This patch is applicable to stable-1.1.

2012-09-10kvm: i386: Add classic PCI device assignmentJan Kiszka3-1/+1917
This adds PCI device assignment for i386 targets using the classic KVM interfaces. This version is 100% identical to what is being maintained in qemu-kvm for several years and is supported by libvirt as well. It is expected to remain relevant for another couple of years until kernels without full-features and performance-wise equivalent VFIO support are obsolete. A refactoring to-do that should be done in-tree is to model MSI and MSI-X support via the generic PCI layer, similar to what VFIO is already doing for MSI-X. This should improve the correctness and clean up the code from duplicate logic. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Acked-by: Acked-by: Michael S.

2012-09-10tcg/s390: fix ld/st with CONFIG_TCG_PASS_AREG0Aurelien Jarno1-7/+7
The load/store slow path has been broken in e141ab52d: - We need to move 4 registers for store functions and 3 registers for load functions and not the reverse. - According to the s390x calling convention the arguments of a function should be zero extended. This means that the register shift should be done with TCG_TYPE_I64 to ensure the higher word is correctly zero extended when needed. I am aware that CONFIG_TCG_PASS_AREG0 is being removed and thus that this patch can be improved, but doing so means it can also be applied to the 1.1 and 1.2 stable branches.

2012-09-09qemu: Use valgrind annotations to mark kvm guest memory as definedChristian Borntraeger2-1/+9
valgrind with kvm produces a big amount of false positives regarding "Conditional jump or move depends on uninitialised value(s)". This happens because the guest memory is allocated with qemu_vmalloc which boils down posix_memalign etc. This function is (correctly) considered by valgrind as returning undefined memory. Since valgrind is based on jitting code, it will not be able to see changes made by the guest to guest memory if this is done by KVM_RUN, thus keeping most of the guest memory undefined. Now lots of places in qemu will then use guest memory to change behaviour. To avoid the flood of these messages, lets declare the whole guest memory as defined. This will reduce the noise and allows us to see real problems. In the future we might want to make this conditional, since there is actually something that we can use those false positives for: These messages will point to code that depends on guest memory, so we can use these backtraces to actually make an audit that is focussed only at those code places. For normal development we dont want to see those messages, though. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2012-09-08target-sparc: fix fcmp{s,d,q} instructions wrt exceptionAurelien Jarno1-40/+27
fcmp{s,d,q} instructions are supposed to ignore quiet NaN (contrary to the fcmpe{s,d,q} instructions), but the current code is wrongly setting the NV exception in that case. Moreover the current code is duplicated: first the arguments are checked for NaN to generate an exception, and later in case the comparison is unordered (which can only happens if one of the argument is a NaN), the same check is done to generate an exception. Fix that by calling clear_float_exceptions() followed by check_ieee_exceptions() as for the other floating point instructions. Use the _compare_quiet functions for fcmp{s,d,q} and the _compare ones for fcmpe{s,d,q}. Simplify the flag setting by not clearing a flag that is set the line just below. This fix allows the math glibc testsuite to pass. Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-09-08MIPS/user: Fix reset CPU state initializationMaciej W. Rozycki3-62/+52
This change updates the CPU reset sequence to use a common piece of code that figures out CPU state flags, fixing the problem with MIPS_HFLAG_COP1X not being set where applicable that causes floating-point MADD family instructions (and other instructions from the MIPS IV FP subset) to trap. As compute_hflags is now shared between op_helper.c and translate.c, the function is now moved to a common header. There are no changes to this function. The problem was seen with the 24Kf MIPS32r2 processor in user emulation. The new approach prevents system and user emulation from diverging -- all the hflags state is initialized in one place now.

2012-09-07pcie_aer: clear cmask for Advanced Error Interrupt Message NumberJason Baron1-0/+5
The Advanced Error Interrupt Message Number (bits 31:27 of the Root Error Status Register) is updated when the number of msi messages assigned to a device changes. Migration of windows 7 on q35 chipset failed because the check in get_pci_config_device() fails due to cmask being set on these bits. Its valid to update these bits and we must restore this state across migration. Signed-off-by: Jason Baron <jbaron@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
