2011-06-19cirrus_vga: reset lfb_addr after a pci config write if the BAR is unmappedStefano Stabellini
If the cirrus_vga PCI BAR is unmapped than we should not only reset map_addr but also lfb_addr, otherwise we'll keep trying to map the old lfb_addr in map_linear_vram.

2011-01-10vga: tag as not hotplugable.Gerd Hoffmann
This patch tags all vga cards as not hotpluggable. The qemu standard vga will never ever be hotpluggable. For cirrus + vmware it might be possible to get that work some day. Todays we can't handle that for a number of reasons though. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2011-01-04cirrus_vga: fix division by 0 for color expansion ropAurelien Jarno
Commit d85d0d3883f5a567fa2969a0396e42e0a662b3fa introduces a regression with Windows ME that leads to a division by 0 and a crash. It uses the color expansion rop with the source pitch set to 0. This is something allowed, as the manual explicitely says "When the source of color-expand data is display memory, the source pitch is ignored.". This patch fixes this regression by computing sx, sy and others variables only if they are going to be used later, that is for a plain copy ROP. It basically consists in moving code. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-12-11Add endianness as io mem parameterAlexander Graf
As stated before, devices can be little, big or native endian. The target endianness is not of their concern, so we need to push things down a level. This patch adds a parameter to cpu_register_io_memory that allows a device to choose its endianness. For now, all devices simply choose native endian, because that's the same behavior as before.

2010-11-22pci: Replace unneeded type casts in calls of pci_register_barStefan Weil

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.

2009-12-12qdev: Replace device names containing whitespaceMarkus Armbruster
Device names with whitespace require quoting in the shell and in the monitor. Some of the offenders are also overly long. Some have a more convenient alias, some don't.

2009-12-03qemu: cleanup unused macros in cirrusMichael S. Tsirkin

2009-12-03qemu: make cirrus init value pci spec compliantMichael S. Tsirkin
PCI memory should be disabled at reset, otherwise we might claim transactions at address 0. I/O should also be disabled, although for cirrus it is harmless to enable it as we do not have I/O bar. Note: bios fix needed for this patch to work was already applied: previously bios incorrently assumed that it does not need to enable i/o unless device has i/o bar. Signed-off-by: Michael S.

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.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
