* ioemu rendering fixesKeir Fraser2008-04-015-15/+47
| | | | | | | | | | | | | | | | | | | | - no need to call the colourdepth callback in text mode: the buffer cannot be shared anyway; - line size changes are currently undetected: since we added a linesize parameter to the resize callback, we also need to detect line size changes and call dpy_resize accordingly; - 8 bit colour depth with the shared framebuffer is broken: in order to fix it I disabled the shared buffer in vnc for the 8bit colour depth case (it has to be done in software anyway..) and implemented paletted colours in both opengl and sdl; - opengl rendering is broken when there is padding in the framebuffer lines: removing unnecessary GL_UNPACK_ALIGNMENT settings so that the GL_UNPACK_ROW_LENGTH parameter can work properly.

* ioemu: actually check for errors in bdrv_flush et alKeir Fraser2008-03-319-18/+30
| | | | | | | | | | | | bdrv_flush is declared to return void, but this is wrong because it means that the implementations have nowhere to report their errors. Indeed, the implementations generally ignore errors. This patch corrects this by making it return int (implicitly, either 0 or -errno, as for other similar functions). All of the implementations and callers are adjusted too. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* ioemu: Fix L1 table endianess of qcow images created by tapdiskKeir Fraser2008-03-261-0/+58
| | | | | | | | | | | | | | | The qemu/ioemu implementation of the qcow format uses a big endian L1 table. tapdisk omits the necessary conversion, so qcow images have the wrong endianess and cannot be read by correct implementations of qcow. This patch detects broken tapdisk images and converts their L1 tables to big endian when the image file is opened in ioemu for the first time. The fixed image has a new flag EXTHDR_L1_BIG_ENDIAN set in the extended header. Note that a converted image cannot be opened by tapdisk again. Signed-off-by: Kevin Wolf <kwolf@suse.de>

* ioemu: SDL rendering using OpenGLKeir Fraser2008-03-184-12/+203
| | | | | | | | | | | | | | | | | | Add opengl support for rendering the guest framebuffer in the SDL window. SDL is needed anyway to open the window and handle the events. Opengl rendering is optional and can be turned off at both compile time and in the vm configuration file. Some of the benefits of using opengl are: - faster rendering, less CPU intensive, especially with good graphic cards; - makes the window resizing possible and hardware accelerated, thus very efficient and smooth; - allows other optimizations like sharing directly a buffer in vram with the guest (not yet implemented).

| | | | | | | | | | Add support for a tap:ioemu pseudo driver. Devices using this driver won't use tapdisk (containing the code duplication) any more, but will connect to the qemu-dm of the domain. In this way no working configuration should be broken right now as you can still choose to use the tapdisk drivers. Signed-off-by: Kevin Wolf <kwolf@suse.de>

* ioemu: sdl blittingKeir Fraser2008-03-034-17/+81
| | | | | | | | | | | | | Right now qemu takes care of converting pixels between the guest pixel format and the sdl pixel format, after that qemu also memcpy the converted pixels to the sdl buffer in video ram. This process can be improved using the SDL blit capabilities: the patch I am attaching creates an SDL Surface from the Cirrus VGA framebuffer and uses SDL blitting functions to convert and write pixels to video ram. SDL blitting functions are optimized and can even be hardware accelerated on some platforms. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | correct log file. At the same time, this patch renames the logfile to be 'qemu-dm-{NAME}.log' instead of qemu-dm-{ID}.log. This makes it easier to track/find the QEMU logfile associated with a VM. It will also save 1 backup qemu-dm-{NAME}.log.1 so if a domain crashes & restart, you don't loose/overwrite the logfile immediately. Finally it changes the QEMU monitor prompt back to '(qemu)' instead of '(HVMXen)' because automated tools /scripts interacting with QEMU's monitor need a consistent prompt to look for & changing it for Xen serves no useful purpose.

| * ioemu: VNC updates should be sent only when requested.Keir Fraser2008-02-261-22/+174
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reading qemu code I realized that the qemu vnc server sometimes sends framebuffer updates even if the client didn't request any. This is not consistent with the RFB protocol spec and can break some clients. This patch strictly enforces compliance with the RFB protocol making sure framebuffer updates are sent only if the client requested one. Doing so is more difficult than it seems because some framebuffer pseudo-encoding updates cannot be discarded but must be sent anyway: for example desktop resize and pixel format change messages. To solve the problem I wrote a queue that stores those messages and sends them as soon as the client asks for an update. Since 90% of the times the queue is used to store only few elements, the queue allocates 10 elements at the beginning and every time it runs out of elements allocates other 10 elements. This is should drastically limit the number of malloc and free needed to maintain the queue. I did some stress tests in the last couple of days and seems to work well.

This is useful for Xen as new OSes may not support the old 100Mbps NICs we currently support (especially on non-x86). Drivers for e1000 should be more readily available.
