2011-08-25cirrus: wrap memory update in a transactionAvi Kivity1-0/+2

2011-08-25ppc_oldworld, ppc_newworld: fix escc BAR related crashAvi Kivity2-3/+8
ppc maps the escc mmio region both at a fixed offset (as a sysbus area) and as part of a PCI BAR. This crashes, since a MemoryRegion may have only one parent. Use an alias so we have a separate MemoryRegion for the BAR. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-08-24gt64xxx: fix crash in gt64120_pci_mapping()Avi Kivity1-1/+5
The map/unmap code was assymetric - unmap used the local MemoryRegion while map used isa_mmio_init(), which cannot handle dynamic mappings. Fix by using isa_mmio_setup() and the local MemoryRegion.

2011-08-24pci: Error on PCI capability collisionsJan Kiszka1-0/+38
Nothing good can happen when we overlap capabilities. This may happen when plugging in assigned devices or when devices models contain bugs. Detect the overlap and report it.

2011-08-23hw/omap_gpmc: Don't try to map CS0 twice on resetPeter Maydell1-1/+0
Remove a spurious second map of the OMAP GPMC CS0 region on reset. This fixes an assertion failure when we try to add the region to its container when it was already added. (The old code did not complain about mismatched map/unmap calls, but the new MemoryRegion implementation does.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Edgar E.

2011-08-22vga: Use linear mapping + dirty logging in chain 4 memory access modeJan Kiszka2-1/+52
Most VGA memory access modes require MMIO handling as they demand weird logic to get a byte from or into the video RAM. However, there is one exception: chain 4 mode with all memory planes enabled for writing. This mode actually allows lineary mapping, which can then be combined with dirty logging to accelerate KVM. This patch accelerates specifically VBE accesses like they are used by grub in graphical mode. Not only the standard VGA adapter benefits from this, also vmware and spice in VGA mode.

2011-08-22440fx: fix PAM, PCI holesAvi Kivity4-46/+115
The current implementation of PAM and the PCI holes is broken in several ways: - PCI BARs are not restricted to the PCI hole (a BAR may hide memory) - PCI devices do not respect PAM (if a PCI device maps a region while PAM maps the region to RAM, the request will be honored) This patch fixes things by introducing a pci address space, and using memory region aliases to represent PAM regions, SMRAM, and PCI holes. The memory hierarchy looks something like system_memory | +--- low memory alias (0-0xe0000000) | | | +-- ram@0 | +--- high memory alias (0x100000000-EOM) | | | +-- ram@0xe0000000 | +--- pci hole alias (end of low memory-0x100000000) | | | +-- pci@end-of-low-memory | | +--- pam[n] (0xc0000-0xc3fff etc) (when set to pci, priority 1) | | | +-- pci@0xc4000 etc | +--- smram (0xa0000-0xbffff) (when set to pci/vga, priority 1) | +-- pci@0xa0000 etc ram (simple ram region) pci | +--- BARn | +--- VGA 0xa0000-0xbffff | +--- ROMs Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
