2009-06-29support colon in filenamesRam Pai1-0/+1
Problem: It is impossible to feed filenames with the character colon because qemu interprets such names as a protocol. For example filename scsi:0, is interpreted as a protocol by name "scsi". This patch allows user to espace colon characters. For example the above filename can now be expressed either as 'scsi\:0' or as file:scsi:0 anything following the "file:" tag is interpreted verbatin. However if "file:" tag is omitted then any colon characters in the string must be escaped using backslash. Here are couple of examples: scsi\:0\:abc is a local file scsi:0:abc http\://myweb is a local file by name http://myweb file:scsi:0:abc is a local file scsi:0:abc file:http://myweb is a local file by name http://myweb Signed-off-by: Ram Pai <linuxram@us.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-03-13DisplayAllocator interface (Stefano Stabellini)aliguori1-0/+1
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

2009-03-05monitor: Rework API (Jan Kiszka)aliguori1-0/+3
Refactor the monitor API and prepare it for decoupled terminals: term_print functions are renamed to monitor_* and all monitor services gain a new parameter (mon) that will once refer to the monitor instance the output is supposed to appear on. However, the argument remains unused for now. All monitor command callbacks are also extended by a mon parameter so that command handlers are able to pass an appropriate reference to monitor output services. For the case that monitor outputs so far happen without clearly identifiable context, the global variable cur_mon is introduced that shall once provide a pointer either to the current active monitor (while processing commands) or to the default one. On the mid or long term, those use case will be obsoleted so that this variable can be removed again. Due to the broad usage of the monitor interface, this patch mostly deals with converting users of the monitor API. A few of them are already extended to pass 'mon' from the command handler further down to internal functions that invoke monitor_printf. At this chance, monitor-related prototypes are moved from console.h to a new monitor.h. The same is done for the readline API.

2009-01-15DisplayState interface change (Stefano Stabellini)aliguori1-0/+3
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

2008-10-31Make bottom halves more robustaliguori1-0/+1
Bottom halves are supposed to not complete until the next iteration of the main loop. This is very important to ensure that guests can not cause stack overflows in the block driver code. Right now, if you attempt to schedule a bottom half within a bottom half callback, you will enter an infinite loop. This patch uses the same logic that we use for the IOHandler loop to make the bottom half processing robust in list manipulation while in a callback. This patch also introduces idle scheduling for bottom halves. qemu_bh_poll() returns an indication of whether any bottom halves were successfully executed. qemu_aio_wait() uses this to immediately return if a bottom half was executed instead of waiting for a completion notification. qemu_bh_schedule_idle() works around this by not reporting the callback has run in the qemu_bh_poll loop. qemu_aio_wait() probably needs some refactoring but that would require a larger code audit. idle scheduling seems like a good compromise.

Replace signalfd with signal handler/pipe. There is no way to interrupt the CPU execution loop when a file descriptor becomes readable. This results in a large performance regression in sparc emulation during bootup. This patch switches us to signal handler/pipe which was originally suggested by Ian Jackson.
