2011-06-19xen: fix interrupt routingStefano Stabellini
Compared to the last version I only added a comment to the code. - remove i440FX-xen and i440fx_write_config_xen we don't need to intercept pci config writes to i440FX anymore; - introduce PIIX3-xen and piix3_write_config_xen we do need to intercept pci config write to the PCI-ISA bridge to update the PCI link routing; - set the number of PIIX3-xen interrupts line to 128; Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-08piix_pci: Introduces Xen specific call for irq.Anthony PERARD
This patch introduces Xen specific call in piix_pci. The specific part for Xen is in write_config, set_irq and get_pirq.

2011-05-08pc, Disable vmport initialisation with Xen.Anthony PERARD
This is because there is not synchronisation of the vcpu register between Xen and QEMU, so vmport can't work properly. This patch introduces no_vmport parameter to pc_basic_device_init. Signed-off-by: Anthony PERARD <anthony.perard@citrix.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-08pc_memory_init: Move memory calculation to the caller.Anthony PERARD
This patch moves above_4g_mem_size and below_4g_mem_size calculation in the caller of pc_memory_init (pc_init1). And the prototype of pc_memory_init is changed because there is no need anymore to have variable pointer and the ram_size parameter.

2010-07-02pc: Fix CMOS info for drives defined with -deviceMarkus Armbruster
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.

2010-05-03hw: better i440 emulationBernhard M. Wiedemann
updated version of an old patch http://xenon.stanford.edu/~eswierk/misc/qemu-linuxbios/qemu-piix-ram-size.patch that together with http://www.mail-archive.com/linuxbios@linuxbios.org/msg02390.html (which is already in coreboot trunk) allows coreboot to autodetect the amount of RAM within qemu/kvm from a register in i440 northbridge. The message on the old patch states: Unfortunately the current version of qemu does not set these registers, but I have patched qemu so that it emulates the i440 more faithfully in this regard.

2010-02-19QEMU e820 reservation patchJes Sorensen
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. This matches a corresponding patch for Seabios, however older versions of Seabios will default to the hardcoded address range and stay compatible with current QEMU.

2009-11-12serial: Add interface to set reference oscillator frequencyStefan Weil
Many (most?) serial interfaces have a programmable clock which provides the reference frequency ("baudbase"). So a fixed baudbase which is only set once can be wrong. omap1.c is an example which could use the new interface to change baudbase when the programmable clock changes. ar7 system emulation (still not part of standard QEMU) is similar to omap and already uses serial_set_frequency.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.
