2011-01-04Fix curses on big endian hostsAurelien Jarno
On big endian hosts, the curses interface is unusable: the emulated graphic card only displays garbage, while the monitor interface displays nothing (or rather only spaces). The curses interface is waiting for data in native endianness, so console_write_ch() should not do any conversion. The conversion should be done when reading the video buffer in hw/vga.c. I supposed this buffer is in little endian mode, though it's not impossible that the data is actually in guest endianness. I currently have no big endian guest to way (they all switch to graphic mode immediately). Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-12-19vga: Declare as little endianBlue Swirl
This patch replaces explicit bswaps with endianness hints to the mmio layer. CC: Alexander Graf <agraf@suse.de> Acked-by: Alexander Graf <agraf@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
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.

2010-08-22VGA: Don't register deprecated VBE rangeAlex Williamson
Old versions of the BOCHs VGA BIOS (cira 2003) made use of VBE registers at 0xff80/81. In VBE API version 0xb0c2 these were moved to 0x1ce/cf. Unfortunately, QEMU still registers handlers for the old range. If a guest attempts to assign an I/O device overlapping this region, QEMU exits with a hw_error. Windows guests seem to like to assign I/O devices to the high end of the address space, so it's pretty easy to hot add an rtl8139 to a Win2k8 guest and trigger the bug. I can't find any reason to register these handlers, so let's remove the cruft. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-06qemu_ram_alloc: Add DeviceState and name parametersAlex Williamson
These will be used to generate unique id strings for ramblocks. The name field is required, the device pointer is optional as most callers don't have a device. When there's no device or the device isn't a child of a bus implementing BusInfo.get_dev_path, the name should be unique for the platform.

2009-12-18VMware VGA: Only enable dirty log tracking when fifo is disabledAnthony Liguori
This patch enables dirty log tracking whenever it's needed and disables it when it is not. We unconditionally enable dirty log tracking on reset, restart dirty log tracking when PCI IO regions are remapped, and disable/enable it based on commands from the guest.

2009-12-18Make sure to enable dirty tracking of VBE vram mappingAnthony Liguori
Apparently, VBE maps the VGA vram to a fixed physical location. KVM requires that all mappings of the VGA vram have dirty tracking enabled on them. Any access to the VGA vram through the VBE mapping currently fails to result in dirty page tracking updates causing a black screen. This is the true root cause of VMware VGA not working correctly under KVM and likely also an issue with some of the std-vga black screen issues too. Cirrus does not enable VBE so it would not be a problem when using Cirrus. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Rebased-by: Dave Airlie <airlied@redhat.com>
2009-11-27Revert "vga: do not resize the screen on hw_invalidate"Aurelien Jarno
This causes ctrl+alt+u or ctrl+alt+f to not work when windows hasn't been resized first. Other graphic emulators do resize the screen on hw_invalidate. This reverts commit 0bd8246bfec1dfb2eb959f52db535572c0260f4c.
2009-11-07v3: don't call reset functions on cpu initializationGlauber Costa
There is absolutely no need to call reset functions when initializing devices. Since we are already registering them, calling qemu_system_reset() should suffice. Actually, it is what happens when we reboot the machine, and using the same process instead of a special case semantics will even allow us to find bugs easier. Furthermore, the fact that we initialize things like the cpu quite early, leads to the need to introduce synchronization stuff like qemu_system_cond. This patch removes it entirely. All we need to do is call qemu_system_reset() only when we're already sure the system is up and running I tested it with qemu (with and without io-thread) and qemu-kvm, and it seems to be doing okay - although qemu-kvm uses a slightly different patch. [ v2: user mode still needs cpu_reset, so put it in ifdef. ] [ v3: leave qemu_system_cond for now. ] Signed-off-by: Glauber Costa <glommer@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-08-27qdev: add return value to init() callbacks.Gerd Hoffmann
Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.

Hi all, currently the vga screen_dump code doesn't use the DisplayState interface properly and tries to replace it temporarily while taking the screenshot.
