2010-11-21pc: disable the BOCHS BIOS panic portBernhard Kohl1-2/+2
We have an OS which writes to port 0x400 when probing for special hardware. This causes an exit of the VM. With SeaBIOS this port isn't used anyway.

2010-07-06qemu_ram_alloc: Add DeviceState and name parametersAlex Williamson1-3/+4
These will be used to generate unique id strings for ramblocks. The name field is required, the device pointer is optional as most callers don't have a device. When there's no device or the device isn't a child of a bus implementing BusInfo.get_dev_path, the name should be unique for the platform.

2010-07-02pc: Fix CMOS info for drives defined with -deviceMarkus Armbruster1-35/+59
Drives defined with -drive if=ide get get created along with the IDE controller, inside machine->init(). That's before cmos_init(). Drives defined with -device get created during generic device init. That's after cmos_init(). Because of that, CMOS has no information on them (type, geometry, translation). Older versions of Windows such as XP reportedly choke on that. Split off the part of CMOS initialization that needs to know about -device devices, and turn it into a reset handler, so it runs after device creation.

2010-06-14pass info about hpets to seabios.]Gleb Natapov1-0/+3
Currently HPET ACPI table is created regardless of whether qemu actually created hpet device. This may confuse some guests that don't check that hpet is functional before using it. Solve this by passing info about hpets in qemu to seabios via fw config interface. Additional benefit is that seabios no longer uses hard coded hpet configuration. Proposed interface supports up to 8 hpets. This is the number defined by hpet spec. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-06-13hpet/rtc: Rework RTC IRQ replacement by HPETJan Kiszka1-6/+8
Allow the intercept the RTC IRQ for the HPET legacy mode. Then push routing to IRQ8 completely into the HPET. This allows to turn hpet_in_legacy_mode() into a private function. Furthermore, this stops the RTC from clearing IRQ8 even if the HPET is in control. This patch comes with a side effect: The RTC timers will no longer be stoppend when there is no IRQ consumer, possibly causing a minor performance degration. But as the guest may want to redirect the RTC to the SCI in that mode, it should normally disable unused IRQ source anyway.

2010-06-13hpet: Convert to qdevJan Kiszka1-1/+6
Register the HPET as a sysbus device and create it that way. As it can route its IRQs to any ISA IRQ, we need to connect it to all 24 of them.

2010-03-16error: Replace qemu_error() by error_report()Markus Armbruster1-3/+3
error_report() terminates the message with a newline. Strip it it from its arguments. This fixes a few error messages lacking a newline: net_handle_fd_param()'s "No file descriptor named %s found", and tap_open()'s "vnet_hdr=1 requested, but no kernel support for IFF_VNET_HDR available" (all three versions). There's one place that passes arguments without newlines intentionally: load_vmstate(). Fix it up.
2010-03-16pc: Factor common code out of pc_boot_set() and cmos_init()Markus Armbruster1-20/+8
Code duplicated in commit 0ecdffbb. The two versions are similar, but not identical: * cmos_init() reports errors to stderr, pc_boot_set() via qemu_error(). The latter is fine for both, so pick that for the common code. * cmos_init() obeys fd_bootchk, pc_boot_set() ignores it. Make it a parameter of the common code.
2010-03-16pc: Fix error reporting for -boot onceMarkus Armbruster1-4/+3
Commit 0ecdffbb created pc_boot_set() for use from monitor command "boot_set", via qemu_boot_set(). pc_boot_set() reports errors to cur_mon, which works fine for monitor code. Commit e0f084bf reused the function int reset handler restore_boot_devices(). Use of cur_mon is problematic in that context. For instance, the "Too many boot devices for PC" error for "-boot order=abcdefgh,once=c" goes to the monitor instead of stderr. The monitor may not even exist. Fix by switching to qemu_error().
2010-03-04x86: Extend validity of bsp_to_cpuJan Kiszka1-1/+2

Hi, Kevin and I have agreed on the approach for this one now. So here is the latest version of the patch for QEMU, submitting e820 reservation entries via fw_cfg. Cheers, Jes Use qemu-cfg to provide the BIOS with an optional table of e820 entries. Notify the BIOS of the location of the TSS+EPT range to by reserving it via the e820 table.
