2009-04-10Make PCI config status register read-onlyaliguori
From the documentation I can find, this register is supposed to be read-only. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@7070 c046a42c-6fe2-441c-8c8c-71466251a162
2009-03-05monitor: Rework API (Jan Kiszka)aliguori
Refactor the monitor API and prepare it for decoupled terminals: term_print functions are renamed to monitor_* and all monitor services gain a new parameter (mon) that will once refer to the monitor instance the output is supposed to appear on. However, the argument remains unused for now. All monitor command callbacks are also extended by a mon parameter so that command handlers are able to pass an appropriate reference to monitor output services. For the case that monitor outputs so far happen without clearly identifiable context, the global variable cur_mon is introduced that shall once provide a pointer either to the current active monitor (while processing commands) or to the default one. On the mid or long term, those use case will be obsoleted so that this variable can be removed again. Due to the broad usage of the monitor interface, this patch mostly deals with converting users of the monitor API. A few of them are already extended to pass 'mon' from the command handler further down to internal functions that invoke monitor_printf. At this chance, monitor-related prototypes are moved from console.h to a new monitor.h. The same is done for the readline API.

2008-12-11pci: add default pci subsystem id for all devices (Gerd Hoffman)aliguori
This sets a default PCI subsystem ID for all emulated PCI devices. PCI specs require this, so do it. In many cases it is enougth to know the PCI ID to handle a device correctly. Sometimes a device driver must identify the exact piece of hardware (via PCI Subsystem ID) though. What does this patch to qemu devices: Right now the emulated PCI devices have no PCI subsystem ID, only the PCI ID. The discussed patch sets a default PCI subsystem ID for all emulated devices. Which will make the qemu devices look pretty much like in the laptop case: all PCI subsystem IDs will point to qemu by default. If a driver emulates a very specific piece of hardware where it has to emulate more than just the PCI chip, it can overwrite the PCI subsystem ID without problems. The es1370 driver does that for example.

2008-12-09KVM: Coalesced MMIO supportaliguori
MMIO exits are more expensive in KVM or Xen than in QEMU because they involve, at least, privilege transitions. However, MMIO write operations can be effectively batched if those writes do not have side effects. Good examples of this include VGA pixel operations when in a planar mode. As it turns out, we can get a nice boost in other areas too. Laurent mentioned a 9.7% performance boost in iperf with the coalesced MMIO changes for the e1000 when he originally posted this work for KVM.
