2010-01-26PCI: Convert pci_info() to QObjectLuiz Capitulino
The returned QObject is a QList of all buses. Each bus is represented by a QDict, which has a key with a QList of all PCI devices attached to it. Each device is represented by a QDict. As has happended to other complex conversions, it's hard to split this commit as part of it are new functions which are called by each other. IMPORTANT: support for printing PCI bridge attached devices is NOT part of this commit, it's going to be added by the next commit, as it's untested.

2010-01-13pci: Add missing 'const' in argument to pci_get_xxxStefan Weil
pci_get_byte, pci_get_word, pci_get_long and pci_get_quad all take a const uint8_t pointer, because they only read the configuration data. Their prototypes should reflect this fact. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-01-11pci: allow loading roms via fw_cfg.Gerd Hoffmann
This patch adds a pci bus property 'rombar' which specifies whenever the pci rom should be loaded via pci rom bar (default) or via fw_cfg. The later can be used for compatibility with older qemu versions where no pci rom bar is present. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-12-18pci romfiles: add property, add default to PCIDeviceInfoGerd Hoffmann
This patch adds a romfile property to the pci bus. It allows to specify a romfile to load into the rom bar of the pci device. The default value comes from a new field in PCIDeviceInfo. The property allows to change the file and also to disable the rom loading using an empty string. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-18Support PCI based option rom loadingAnthony Liguori
Currently, we preload option roms into the option rom space in memory. This prevents DDIM from functioning correctly which severely limits the number of roms we can support. This patch introduces a pci_add_option_rom() which registers the PCI_ROM_ADDRESS bar which points to our option rom. It also converts over the cirrus vga adapter, the rtl8139, virtio, and the e1000 to use this new mechanism. The result is that PXE boot functions even with three unique types of cards.

2009-11-09pci: implement pci bridge filtering.Isaku Yamahata
This patch implements pci bridge filtering. TODO: currently almost all the map funcions assumes filtered_size == size and addr & ~(size - 1) == addr.

2009-11-09pci: initialize pci config headers depending it pci header type.Isaku Yamahata
- Only sets default subsystem id for header type 00.(normal header type) because header type 01 doesn't have subsystem id, and uses the register for other purpose. So setting default subsystem id doesn't make sense. - initialize wmask more for header type 01.(bridge header type) Without those wmasks, linux was confused not boot, and lspci was confused not to print out expected IO/memory range.

2009-11-09pci: add helper functions to check ranges overlap.Isaku Yamahata
add helper function to check ranges overlap suggested by Michael S. Tsirkin <mst@redhat.com>. His original suggestion was to use [first, last], however I chosen to use offset, length pair, i.e. [offset, offset + length) because pci configuration space related functions all uses offset and length pair, so it helps to avoid to type constant twice.

2009-11-09pci: make pci configuration transaction more accurate.Isaku Yamahata
This patch sorts out/enhances pci code to track pci bus topology more accurately. - Track host bus bridge with pci domain number. Although the current qemu implementation supports only pci domian 0 yet. - Track pci bridge parent-child relationship. When looking down from pci host bus for pci sub bus, be aware of secondary bus/subordinate bus. Thus pci configuration transaction is more accurately emulated. This patch adds new member to PCIBus to track pci bus topology. Since qdev already tracks down bus relationship, those new member wouldn't be necessary. However it would be addressed later because not all the pci device isn't converted to qdev yet.

2009-11-09pci: 64bit bar support.Isaku Yamahata
implemented pci 64bit bar support. The tricky bit is pci_update_mapping(). An OS is allowed to set the BAR such that OS can't address the area pointed by BAR. It doesn't make sense, though. In that case, don't map the BAR. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-09pci: typedef pcibus_t as uint64_t instead of uint32_t.Isaku Yamahata
This patch is preliminary for 64bit bar. For 64bit bar support, change pcibus_t which represents pci bus addr/size from uint32_t to uint64_t. And also change FMT_pcibus for printf. In pci_update_mapping() checks 32bit overflow. So the check must be updated too. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-10-05Fix pci_add nic not to exit on bad modelMarkus Armbruster
Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to create the NIC. When MODEL is unknown or "?", this prints to stderr and terminates the program. Change pci_nic_init() not to treat "?" specially, and to return NULL on failure. Switch uses during startup to new convenience wrapper pci_nic_init_nofail(), which behaves just like pci_nic_init() used to do. Bonus bug fix: we now check for qdev_init() failing there.

2009-10-05Fix pci_add storage not to exit on bad first argumentMarkus Armbruster
Monitor command "pci_add ADDR storage ..." does its work in qemu_pci_hot_add_nic(). It called pci_create(..., ADDR) to create the device. That's wrong, because pci_create() terminates the program when ADDR is invalid. Use pci_get_bus_devfn() and pci_create_noinit() instead.
