2009-01-16fix screendump (Stefano Stabellini)aliguori1-2/+1
this patch fixes the screendump functionality that was recently broken; it must be applied *after* PATCH 5, 6 and 7 of the original displaystate change patch series. In fact the other patches make much easier to solve the screendump problem because they make the console switching mechanism more robust.

2009-01-16graphical_console_init change (Stefano Stabellini)aliguori1-2/+1
Patch 5/7 This patch changes the graphical_console_init function to return an allocated DisplayState instead of a QEMUConsole. This patch contains just the graphical_console_init change and few other modifications mainly in console.c and vl.c. It was necessary to move the display frontends (e.g. sdl and vnc) initialization after machine->init in vl.c. This patch does *not* include any required changes to any device, these changes come with the following patches. Patch 6/7 This patch changes the QEMUMachine init functions not to take a DisplayState as an argument because is not needed any more; In few places the graphic hardware initialization function was called only if DisplayState was not NULL, now they are always called. Apart from these cases, the rest are all mechanical substitutions. Patch 7/7 This patch updates the graphic device code to use the new graphical_console_init function. As for the previous patch, in few places graphical_console_init was called only if DisplayState was not NULL, now it is always called. Apart from these cases, the rest are all mechanical substitutions.

2009-01-15DisplayState interface change (Stefano Stabellini)aliguori1-0/+2
This patch changes the DisplayState interface adding support for multiple frontends at the same time (sdl and vnc) and implements most of the benefit of the shared_buf patch without the added complexity. Currently DisplayState is managed by sdl (or vnc) and sdl (or vnc) is also responsible for allocating the data and setting the depth. Vga.c (or another backend) will do any necessary conversion. The idea is to change it so that is vga.c (or another backend) together with console.c that fully manage the DisplayState interface allocating data and setting the depth (either 16 or 32 bit, if the guest uses a different resolution or is in text mode, vga.c (or another backend) is in charge of doing the conversion seamlessly). The other idea is that DisplayState supports *multiple* frontends like sdl and vnc; each of them can register some callbacks to be called when a display event occurs. The interesting changes are: - the new structures and related functions in console.h and console.c in particular the following functions are very helpful to manage a DisplaySurface: qemu_create_displaysurface qemu_resize_displaysurface qemu_create_displaysurface_from qemu_free_displaysurface - console_select and qemu_console_resize in console.c this two functions manage multiple consoles on a single host display - moving code around in hw/vga.c as for the shared_buf patch this is necessary to be able to handle a dynamic DisplaySurface bpp - changes to vga_draw_graphic in hw/vga.c this is the place where the DisplaySurface buffer is shared with the videoram, when possible; Compared to the last version the only changes are: - do not remove support to dpy_copy in cirrus_vga - change the name of the displaysurface handling functions Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6336 c046a42c-6fe2-441c-8c8c-71466251a162
2009-01-05Add cirrus reset handlerblueswir11-0/+1
The vga reset handler overwrites some cirrus registers, causing reboots to corrupt cirrus state to the point that guests can only bring up 640x480 resolutions. Fix by adding a dedicated cirrus reset handler (which calls the common vga handler).

2008-11-24vga optimization (Glauber Costa)aliguori1-0/+9
Hypervisors like KVM perform badly while doing mmio on a loop, because it'll generate an exit on each access. This is the case with VGA, which results in very bad performance. In this patch, we map the linear frame buffer as RAM, make sure it has dirty region tracking enabled, and then just let the region to be written.
