2012-02-24scsi: fix searching for an empty idPaolo Bonzini1-5/+10
The conditions for detecting no free target or LUN were wrong. The LUN loop was followed by an "if" condition that is never true, because the loop is exited as soon as lun becomes equal to bus->info->max_lun, and never becomes greater than it. The target loop had a wrong condition (<= instead of <). Once this is fixed, the loop would fail in the same way as the LUN loop. The fix is to see whether scsi_device_find returned the device with the last (channel, target, LUN) pair, and fail if so. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-02-17i8259: Do not clear level-triggered lines in IRR on initJan Kiszka3-3/+3
When an input line is handled as level-triggered, it will immediately raise an IRQ on the output of a PIC again that goes through an init reset. So only clear the edge-triggered inputs from IRR in that scenario. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-17i8254: Factor out pit_get_channel_infoJan Kiszka3-34/+29
Instead of providing 4 individual query functions for mode, gate, output and initial counter state, introduce a service that queries all information at once. This comes with tiny additional costs for pcspk_callback but with a much cleaner interface. Also, it will simplify the implementation of the KVM in-kernel PIT model.

2012-02-17i8254: Rework & fix interaction with HPET in legacy modeJan Kiszka5-48/+57
When the HPET enters legacy mode, the IRQ output of the PIT is suppressed and replaced by the HPET timer 0. But the current code to emulate this was broken in many ways. It reset the PIT state after re-enabling, it worked against a stale static PIT structure, and it did not properly saved/restored the IRQ output mask in the PIT vmstate. This patch solves the PIT IRQ control in a different way. On x86, it both redirects the PIT IRQ to the HPET, just like the RTC. But it also keeps the control line from the HPET to the PIT. This allows to disable the PIT QEMU timer when it is not needed. The PIT's view on the control line state is now saved in the same format that qemu-kvm is already using. Note that, in contrast to the suppressed RTC IRQ line, we do not need to save/restore the PIT line state in the HPET. As we trigger a PIT IRQ update via the control line, the line state is reconstructed on mode switch.

2012-02-17i8254: Pass alternative IRQ output object on initializationJan Kiszka9-12/+12
HPET legacy emulation will require control over the PIT IRQ output. To enable this, add support for an alternative IRQ output object to the PIT factory function. If the isa_irq number is < 0, this object will be used. This also removes the IRQ number property from the PIT class as we now use a generic GPIO output pin that is connected by the factory function.

2012-02-17hpet: Save/restore cached RTC IRQ levelJan Kiszka1-0/+29
In legacy mode, the HPET suppresses the RTC interrupt delivery via IRQ 8 but keeps track of the RTC output level and applies it when legacy mode is turned off again. This value has to be preserved across save/ restore as it cannot be reconstructed otherwise. To document that a raised rtc_irq_level won't survive a vmload without a hpet/rtc_irq_level subsection, add an explicit clearing to the reset handler.

2012-02-17i8254: Do not raise IRQ level on resetJan Kiszka1-1/+7
Avoid changing the IRQ level to high on reset as it may trigger spurious events. Instead, open-code the effects of pit_load_count(0) in the reset handler. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-17qdev: Fix qdev_try_create() semanticsAndreas Färber1-0/+3
Since QOM'ification, qdev_try_create() uses object_new() internally, which asserts "type != NULL" when the type is not registered. This was revealed by the combination of kvmclock's kvm_enabled() check and early QOM type registration. Check whether the class exists before calling object_new(), so that the caller (e.g., qdev_create) can fail gracefully, telling us which device could not be created.

2012-02-17hw/pl031: Actually raise interrupt on timer expiryPeter Maydell1-1/+1

2012-02-17arm_boot: Pass base address of GIC CPU interface, not whole GICPeter Maydell5-13/+18
The arm_boot secondary boot loader code needs the address of the GIC CPU interface. Obtaining this from the base address of the private peripheral region was possible for A9 and 11MPcore, but the A15 puts the GIC CPU interface in a different place. So make boards pass in the GIC CPU interface address directly. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-02-17hw/vexpress.c: Instantiate the motherboard CLCDPeter Maydell1-1/+1
Instantiate the CLCD on the vexpress motherboard as well as one on the daughterboard -- the A15 daughterboard does not have a CLCD and so relies on the motherboard one. At the moment QEMU doesn't provide infrastructure for selecting which display device gets to actually show graphics -- the first one registered is it. Fortunately this works for the major use case (Linux): if the daughterboard has a CLCD it will come first and be used, otherwise we fall back to the motherboard CLCD. So we don't (currently) need to implement the control register which allows software to tell the mux which video output to pass through to the outside world.

2012-02-17hw/vexpress.c: Move secondary CPU boot code to SRAMPeter Maydell1-14/+2
On real Versatile Express hardware, the boot ROM puts the secondary CPU bootcode/holding pen in SRAM. We can therefore rely on Linux not trashing this memory until secondary CPUs have booted up, and can put our QEMU-specific pen code in the same place. This allows us to drop the odd "hack" RAM page we were using before. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
