* qdev: update pci device registration.Gerd Hoffmann2009-07-091-1/+9
| | | | | | | | | Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunch of parameters. Also adds config_read and config_write callbacks to PCIDeviceInfo, so drivers needing these can be converted to the qdev device API too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
* monitor: Drop pci_addr prefix from hotplug commandsJan Kiszka2009-06-291-1/+2

* qemu/pci: MSI-X support functionsMichael S. Tsirkin2009-06-241-0/+23
| | | | | | | | | | | Add functions implementing MSI-X support. First user will be virtio-pci. Note that platform must set a flag to declare MSI supported: this is a safety measure to avoid breaking platforms which should support MSI-X but currently lack this in the interrupt controller emulation. For PC this will be set by APIC. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* qemu/pci: check constant registers on loadMichael S. Tsirkin2009-06-241-0/+5
| | | | | | | | | | | | | | Add "cmask" table of constant register masks: if a bit is not writeable and is set in cmask table, this bit is checked on load. An attempt to load an image that would change such a register causes load to fail. Use this table to make sure that load does not modify registers that guest can not change (directly or indirectly). Note: we can't just assume that read-only registers never change, because the guest could change a register indirectly. Signed-off-by: Michael S.

* qemu/pci: make default_write_config use mask tableMichael S. Tsirkin2009-06-241-1/+17
| | | | | | | | | | | | | | | | Change much of hw/pci to use symbolic constants and a table-driven design: add a mask table with writable bits set and readonly bits unset. Detect change by comparing original and new registers. This makes it easy to support capabilities where read-only/writeable bit layout differs between devices, depending on capabilities present. As a result, writing a single byte in BAR registers now works as it should. Writing to upper limit registers in the bridge also works as it should. Code is also shorter. Signed-off-by: Michael S.

* Make first argument of monitor command pci_add workMarkus Armbruster2009-06-221-1/+1
| | | | | | | | | | | Simply pass the PCI address through qemu_pci_hot_add_nic() to pci_nic_init() and through qemu_pci_hot_add_storage() to pci_create(). Before, pci_device_hot_add() passed along the PCI bus to use, and ignored any user-specified slot.

* Support addr=... in option argument of -net nicMarkus Armbruster2009-06-221-2/+2
| | | | | | | | | | | | | | | | | Make net_client_init() accept addr=, put the value into struct NICinfo. Use it in pci_nic_init(), and remove arguments bus and devfn. Don't support addr= in third argument of monitor command pci_add, because that clashes with its first argument. Admittedly unelegant. Machines "malta" and "r2d" have a default NIC with a well-known PCI address. Deal with that the same way as the NIC model: make pci_nic_init() take an optional default to be used when the user doesn't specify one.

* Clean some PCI defines (Stefan Weil)aliguori2009-03-281-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this patch adds some more defines from linux/pci_regs.h to hw/pci.h. There is now no longer a need to define them in eepro100.c, so they were removed there. Some defines from linux/pci_regs.h had similar, but not the same defines in hw/pci.h (PCI_REVISION_ID / PCI_REVISION, PCI_SUBSYSTEM_VENDOR_ID / PCI_SUBVENDOR_ID, PCI_SUBSYSTEM_ID / PCI_SUBDEVICE_ID). I suggest to use the "standard" from linux/pci_regs.h and replace the "old" Qemu ones. To facilitate the migration, my patch does not remove the old defines but marks them as obsolete. After a migration to the "standard" defines, pci.h could use linux/pci_regs.h which is far more complete. The patch is needed for an updated maintainer version of hw/eepro100.c which I'd like to see in Qemu stable. * Remove declarations already declared in header file from eepro100.c * Add missing declarations from pci_regs.h to pci.h * Mark "non-standard" declarations in pci.h as obsolete Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6901 c046a42c-6fe2-441c-8c8c-71466251a162

* monitor: Rework API (Jan Kiszka)aliguori2009-03-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch 5/7 This patch changes the graphical_console_init function to return an allocated DisplayState instead of a QEMUConsole. This patch contains just the graphical_console_init change and few other modifications mainly in console.c and vl.c. It was necessary to move the display frontends (e.g. sdl and vnc) initialization after machine->init in vl.c. This patch does *not* include any required changes to any device, these changes come with the following patches. Patch 6/7 This patch changes the QEMUMachine init functions not to take a DisplayState as an argument because is not needed any more; In few places the graphic hardware initialization function was called only if DisplayState was not NULL, now they are always called. Apart from these cases, the rest are all mechanical substitutions. Patch 7/7 This patch updates the graphic device code to use the new graphical_console_init function. As for the previous patch, in few places graphical_console_init was called only if DisplayState was not NULL, now it is always called.

* pci: add default pci subsystem id for all devices (Gerd Hoffman)aliguori2008-12-111-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
