2010-04-08update bochs vbe interfaceGerd Hoffmann1-2/+4
The bochs vbe interface got a new register a while back, which specifies the linear framebuffer size in 64k units. This patch adds support for the new register to qemu.

2009-12-18VMware VGA: Only enable dirty log tracking when fifo is disabledAnthony Liguori1-0/+22
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 Liguori1-0/+24
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 Jarno1-3/+3
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 Costa1-1/+0
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>

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-9/+9
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-08-27qdev: add return value to init() callbacks.Gerd Hoffmann1-2/+3
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.

2009-08-24make vga screen_dump use DisplayState properlyStefano Stabellini1-69/+21
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. A better approach is to register a DisplayChangeListener, call vga_hw_update, and finally write the ppm in the next call from dpy_update. Testing is appreciated.

2009-05-22Introduce reset notifier orderJan Kiszka1-1/+1
Add the parameter 'order' to qemu_register_reset and sort callbacks on registration. On system reset, callbacks with lower order will be invoked before those with higher order. Update all existing users to the standard order 0. Note: At least for x86, the existing users seem to assume that handlers are called in their registration order. Therefore, the patch preserves this property. If someone feels bored, (s)he could try to identify this dependency and express it properly on callback registration.

2009-04-17vga: Cleanup dirty logging (Jan Kiszka)aliguori1-17/+0
In theory, there are no more quirks in the KVM slot management that requires dirty log start/stop all over the place. We just have to start the logging each time the mapping may have changed. This patch drops vga_dirty_log_stop for both standard and cirrus VGA. It also reverts #6851 as it was obviously a tribute to the old slot system.
