* DisplayAllocator interface (Stefano Stabellini)aliguori2009-03-131-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi all, this patch adds a DisplayAllocator interface that allows display frontends (sdl in particular) to provide a preallocated display buffer for the graphical backend to use. Whenever a graphical backend cannot use qemu_create_displaysurface_from because its own internal pixel format cannot be exported directly (text mode or graphical mode with color depth 8 or 24), it creates another display buffer in memory using qemu_create_displaysurface and does the conversion. This new buffer needs to be blitted into the sdl surface buffer every time we need to update portions of the screen. We can avoid this using the DisplayAllocator interace: sdl provides its own implementation of qemu_create_displaysurface, giving back the sdl surface buffer directly (as we used to do before the DisplayState changes). Since the buffer returned by sdl could be in bgr format we need to put back in the handlers of that case. This approach is good if the two following conditions are true: 1) the sdl surface is a software surface that resides in main memory; 2) the host display color depth is either 16 or 32 bpp. If first condition is false we can have bad performances using sdl and vnc together. If the second condition is false performances are certainly not going to improve but they shouldn't get worse either. The first condition is always true, at least on linux/X11 systems; but I believe is true also on other platforms. The second condition is true in the vast majority of the cases. This patch should also have the good side effect of solving the sdl 2D slowness malc was reporting on MacOS, because SDL_BlitSurface is not going to be called anymore when the guest is in text mode or 24bpp. However the root problem is still present so I suspect we may still see some slowness on MacOS when the guest is in 32 or 16 bpp. 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@6839 c046a42c-6fe2-441c-8c8c-71466251a162

* vnc fixes and improvements (Stefano Stabellini)aliguori2009-01-261-0/+17
| | | | | | | | | | | | | | | | | this patch fixes a bug and improves the generic pixel conversion function in vnc.c. The bug is that when a new vnc client connects we need to reset the flag has_WMVi but currently we don't. The generic pixel conversion function is vnc_convert_pixel and currently is not very efficient since uses the division and multiplication operators. To make it more efficient I changed to use bit shift operators instead.

* re-fix screendump (Stefano Stabellini)aliguori2009-01-211-0/+2
| | | | | | | | | | | | | | | Removing the assumption about a single graphic console made get_graphic_console return NULL when called by vga_screen_dump. In this case returning NULL is correct but since NULL is not handled in qemu_console_resize it causes a segmentation fault. Just returning immediately from qemu_console_resize is sufficient to fix the problem.

* Fix character devices after DisplayState refactoringaliguori2009-01-161-6/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The DisplayState refactoring changed the machine init function to create a DisplayState for each VGA device instead of being passed an existing DisplayState. This change is critical to enable multiple graphics device support. Unfortunately, the serial/parallel/console code is structured today to run before machine init to fill out the CharDriverState table which the machine init function uses to determine whether to create the required devices. Since a 'vc' is a type of CharDriverState, the CharDriverState code requires that a DisplayState exist before it runs creating a circular dependency. To fix this, this splits the creation of the initial CharDriverState from the initialization of the text console. We can then in a second step associate a DisplayState with all TextConsoles. This allows us to create the CharDriverState's first, machine init, then associate the TextConsoles with a DisplayState. This code screams for more cleanup.

* graphical_console_init change (Stefano Stabellini)aliguori2009-01-161-18/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* DisplayState interface change (Stefano Stabellini)aliguori2009-01-151-27/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
