2014-04-01linux-user: pass correct host flags to accept4()Petar Jovanovic
Flags NONBLOCK and CLOEXEC can have different values on the host and the guest, so set correct host values before calling accept4(). This fixes several issues with accept4 system call and user-mode of QEMU.

2014-03-31configure: add option to disable -fstack-protector flagsSteven Noonan
The -fstack-protector flag family is useful for ensuring safety and for debugging, but has a performance impact. Here are some boot time comparisons of the various versions of -fstack-protector using qemu-system-arm on an x86_64 host: # -fstack-protector-all Startup finished in 1.810s (kernel) + 12.331s (initrd) + 49.016s (userspace) = 1min 3.159s Startup finished in 1.801s (kernel) + 12.287s (initrd) + 47.925s (userspace) = 1min 2.013s Startup finished in 1.812s (kernel) + 12.302s (initrd) + 47.995s (userspace) = 1min 2.111s # -fstack-protector-strong Startup finished in 1.744s (kernel) + 11.223s (initrd) + 44.688s (userspace) = 57.657s Startup finished in 1.721s (kernel) + 11.222s (initrd) + 44.194s (userspace) = 57.138s Startup finished in 1.693s (kernel) + 11.250s (initrd) + 44.426s (userspace) = 57.370s # -fstack-protector Startup finished in 1.705s (kernel) + 11.409s (initrd) + 43.563s (userspace) = 56.677s Startup finished in 1.877s (kernel) + 11.137s (initrd) + 43.719s (userspace) = 56.734s Startup finished in 1.708s (kernel) + 11.141s (initrd) + 43.628s (userspace) = 56.478s # no stack protector Startup finished in 1.743s (kernel) + 11.190s (initrd) + 43.709s (userspace) = 56.643s Startup finished in 1.763s (kernel) + 11.216s (initrd) + 43.767s (userspace) = 56.747s Startup finished in 1.711s (kernel) + 11.283s (initrd) + 43.878s (userspace) = 56.873s This patch introduces a configure option to disable the stack protector entirely, and conditional stack protector flag selection (in order, based on availability): -fstack-protector-strong, -fstack-protector-all, no stack protector.

2014-03-31pci: Fix clearing IRQs on resetCole Robinson
irq_state is cleared before calling pci_device_deassert_intx, but the latter misbehaves if the former isn't accurate. In this case, any raised IRQs are not cleared, which hits an assertion in pcibus_reset: qemu-system-x86_64: hw/pci/pci.c:250: pcibus_reset: Assertion `bus->irq_count[i] == 0' failed. pci_device_deassert_intx should clear irq_state anyways, so add an assert. This fixes migration with usb2 + usb-tablet.

2014-03-31cpu: Avoid QOM casts for CPU()Andreas Färber
CPU address spaces touching load and store helpers as well as the movement of (almost) all fields from CPU_COMMON to CPUState have led to a noticeable increase of CPU() usage in "hot" paths for both TCG and KVM. While CPU()'s OBJECT_CHECK() might help detect development errors, i.e. in form of crashes due to QOM vs. non-QOM mismatches rather than QOM type mismatches, it is not really needed at runtime since mostly used in CPU-specific paths, coming from a target-specific CPU subtype. If that pointer is damaged, other errors are highly likely to occur elsewhere anyway. Keep the CPU() macro for a consistent developer experience and for flexibility to exchange its implementation, but turn it into a pure, unchecked C cast for now. Compare commit 6e42be7cd10260fd3a006d94f6c870692bf7a2c0.

2014-03-31target-i386: x86_cpu_get_phys_page_debug(): support 1GB page translationLuiz Capitulino
Linux guests, when using more than 4GB of RAM, may end up using 1GB pages to store (kernel) data. When this happens, we're unable to debug a running Linux kernel with GDB: (gdb) p node_data[0]->node_id Cannot access memory at address 0xffff88013fffd3a0 (gdb) GDB returns this error because x86_cpu_get_phys_page_debug() doesn't support translating 1GB pages in IA-32e paging mode and returns an error to GDB.

2014-03-27Don't enable a HPET timer if HPET is disabledMatt Lupfer
A HPET timer can be started when HPET is not yet enabled. This will not generate an interrupt to the guest, but causes problems when HPET is later enabled. A timer that is created and expires at least once before HPET is enabled will have an initialized comparator based on a hpet_offset of 0 (uninitialized). When HPET is enabled, hpet_set_timer() is called a second time, which modifies the timer expiry to a time based on the difference between current ticks (measured with the newly initialized hpet_offset) and the timer's comparator (which was generated before hpet_offset was initialized). This results in a long period of no HPET timer ticks. When this occurs with a CentOS 5.x guest, the guest may not receive timer interrupts during its narrow timer check window and panic on boot.

Currently for both qemu-system-arm and qemu-system-aarch64 the default board model if the user doesn't specify one is the 'integratorcp'. This is a totally arbitrary historical accident since it was the first board to be modelled. That board is now just one target among many for us, and is a very poor choice of default: * it's an ancient board that is now only found in the junkpiles of longtime ARM/Linux hackers, if at all * it's an ARMv5 CPU, when most distros are now assuming ARMv7 * it's pretty much unmaintained in QEMU * it doesn't even have versatilepb's advantage of supporting PCI Making it or any other board the default serves only to confuse people new to ARM who expect something more like the x86 monoculture. Remove the is_default marker from integratorcp, and don't set it for any other board, to give users a nudge that they need to think about which board they want a QEMU model of.
