2016-01-13isa: Clean up inappropriate hw_error()Markus Armbruster1-11/+0
isa_bus_irqs(), isa_create() and isa_try_create() call hw_error() when passed a null bus. Use of hw_error() has always been questionable, because these are used only during machine initialization, and printing CPU registers isn't useful there. Since the previous commit, passing a null bus is a programming error. Drop the hw_error() and simply let it crash. Cc: Richard Henderson <rth@twiddle.net> Cc: "Michael S.

2016-01-13isa: Clean up error handling around isa_bus_new()Markus Armbruster5-7/+19
We can have at most one ISA bus. If you try to create another one, isa_bus_new() complains to stderr and returns null. isa_bus_new() is called in two contexts, machine's init() and device's realize() methods. Since complaining to stderr is not proper in the latter context, convert isa_bus_new() to Error. Machine's init(): * mips_jazz_init(), called from the init() methods of machines "magnum" and "pica" * mips_r4k_init(), the init() method of machine "mips" * pc_init1() called from the init() methods of non-q35 PC machines * typhoon_init(), called from clipper_init(), the init() method of machine "clipper" These callers always create the first ISA bus, hence isa_bus_new() can't fail. Simply pass &error_abort. Device's realize(): * i82378_realize(), of PCI device "i82378" * ich9_lpc_realize(), of PCI device "ICH9-LPC" * pci_ebus_realize(), of PCI device "ebus" * piix3_realize(), of PCI device "pci-piix3", abstract parent of "PIIX3" and "PIIX3-xen" * piix4_realize(), of PCI device "PIIX4" * vt82c686b_realize(), of PCI device "VT82C686B" Propagate the error. Note that these devices are typically created only by machine init() methods with qdev_init_nofail() or similar. If we screwed up and created an ISA bus before that call, we now give up right away. Before, we'd hobble on, and typically die in isa_bus_irqs(). Similar if someone finds a way to hot-plug one of these critters. Cc: Richard Henderson <rth@twiddle.net> Cc: "Michael S.

2015-10-22hw/isa/lpc_ich9: inject the SMI on the VCPU that is writing to APM_CNTLaszlo Ersek1-1/+1
Commit 4d00636e97b7 ("ich9: Add the lpc chip", Nov 14 2012) added the ich9_apm_ctrl_changed() ioport write callback function such that it would inject the SMI, in response to a write to the APM_CNT register, on the first CPU, invariably. Since this register is used by guest code to trigger an SMI synchronously, the interrupt should be injected on the VCPU that is performing the write. apm_ioport_writeb() is the .write callback of the "apm_ops" MemoryRegionOps [hw/isa/apm.c]; it is parametrized to call ich9_apm_ctrl_changed() by ich9_lpc_init() [hw/isa/lpc_ich9.c], via apm_init(). Therefore this change affects no other board. ich9_generate_smi() is an unrelated function that is called by the TCO watchdog; a watchdog is likely in its right to (asynchronously) inject interrupts on the first CPU only. This patch allows the combined edk2/OVMF SMM driver stack to work with multiple VCPUs on TCG, using both qemu-system-i386 and qemu-system-x86_64.

2015-07-08ich9: implement strap SPKR pin logicPaulo Alcantara1-0/+6
If the signal is sampled high, this indicates that the system is strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system reboot feature). The status of this strap is readable via the NO_REBOOT bit (CC: offset 0x3410:bit 5). The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit may be set or cleared by software if the strap is sampled low but may not override the strap when it indicates "No Reboot". This patch implements the logic where hardware has ability to set SPKR pin through a property named "noreboot" and it's sampled high by default.

2015-07-07ich9: add TCO interface emulationPaulo Alcantara1-2/+13
This interface provides some registers within a 32-byte range and can be acessed through PCI-to-LPC bridge interface (PMBASE + 0x60). It's commonly used as a watchdog timer to detect system lockups through SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If NO_REBOOT bit is not set in GCS (General Control and Status register), the system will be resetted upon second timeout if TCO_RLD register wasn't previously written to prevent timeout. This patch adds support to TCO watchdog logic and few other features like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection, etc. are not implemented yet.

2015-07-06piix4/ich9: do not raise SMI on ACPI enable/disable commandsPaolo Bonzini1-0/+3
These commands are handled entirely by QEMU. Do not raise an SMI when they happen, because Windows (at least 2008r2) expects these commands to work and (depending on the value of APMC_EN at startup) the firmware might not have installed an SMI handler. When this happens (e.g. the kernel supports SMIs, or you are using TCG, but you have used "-machine smm=off") RIP is moved to 0x38000 where there is no code to execute. Acked-by: Michael S.

2015-04-02hw: Mark devices picking up char backends actively FIXMEMarkus Armbruster1-0/+2
Character devices defined with -serial and -parallel are for board initialization to wire up. Board code examines serial_hds[] and parallel_hds[] to find them, and creates devices with their qdev chardev properties set accordingly. Except a few devices go on a fishing expedition for a suitable backend instead of exposing a chardev property for board code to set: they use serial_hds[] (often via qemu_char_get_next_serial()) or parallel_hds[] in their realize() or init() method to connect to a backend. Picking up backends that way works when the devices are created by board code. But it's inappropriate for -device or device_add. Not only is it inconsistent with how the other characrer device models work (they connect to a backend explicitly identified by a "chardev" property), it breaks when the backend has been picked up by the board or a previous -device / device_add already. Example: $ qemu-system-ppc64 -M bamboo -S -device i82378 -device pc87312 -device pc87312 qemu-system-ppc64: -device pc87312: Property 'isa-parallel.chardev' can't take value 'parallel0', it's in use Mark them with suitable FIXME comments.

Device models should access their block backends only through the block-backend.h API. Convert them, and drop direct includes of inappropriate headers. Just four uses of BlockDriverState are left: * The Xen paravirtual block device backend (xen_disk.c) opens images itself when set up via xenbus, bypassing blockdev.c. I figure it should go through qmp_blockdev_add() instead. * Device model "usb-storage" prompts for keys. No other device model does, and this one probably shouldn't do it, either. * ide_issue_trim_cb() uses bdrv_aio_discard() instead of blk_aio_discard() because it fishes its backend out of a BlockAIOCB, which has only the BlockDriverState. * PC87312State has an unused BlockDriverState[] member.

Moving properties adding into instances_init will fix missing property error when global/compat property mechanism is used.

After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2014-05-05PortioList: Store PortioList in device stateKirill Batuzov1-3/+8
PortioList is an abstraction used for construction of MemoryRegionPortioList from MemoryRegionPortio. It can be used later to unmap created memory regions. It also requires proper cleanup because some of the memory inside is allocated dynamically. By moving PortioList ot device state we make it possible to cleanup later and avoid leaking memory. This change spans several target platforms. The following testcases cover all changed lines: qemu-system-ppc -M prep qemu-system-i386 -vga qxl qemu-system-i386 -M isapc -soundhw adlib -device ib700,id=watchdog0,bus=isa.0 Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
