2010-07-26vnc: better default values for VNC optionsCorentin Chary1-7/+7
vnc_jpeg and vnc_png are now "auto" by default, this means that if the dependencies are installed (libjpeg or libpng), then they will be enabled. vnc_thread is disabled by default. It should be enabled by default as soon as it's stable enougth. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-07-26vnc: threaded VNC serverCorentin Chary7-26/+682
Implement a threaded VNC server using the producer-consumer model. The main thread will push encoding jobs (a list a rectangles to update) in a queue, and the VNC worker thread will consume that queue and send framebuffer updates to the output buffer. The threaded VNC server can be enabled with ./configure --enable-vnc-thread. If you don't want it, just use ./configure --disable-vnc-thread and a syncrhonous queue of job will be used (which as exactly the same behavior as the old queue). If you disable the VNC thread, all thread related code will not be built and there will be no overhead.

2010-07-26vnc: tight: stop using qdict for palette stuffCorentin Chary4-129/+235
Profiling with callgrind seems to show that a lot of time is spent in the palette code (mostly due to memory allocation and qdict to int conversion). This patch adds a VncPalette implementation. The palette is stored in a hash table, like qdict, but which does way less memory allocations, and doesn't suffer from the QObject overhead.

2010-07-26vnc: tight: specific zlib level and filters for each compression levelCorentin Chary1-1/+18
Disable png filters for lower compression levels. This should lower the CPU consumption and reduce encoding time. This isn't in tight_conf because: * tight_conf structure must not change, because it's shared with other tight implementations (libvncserver, etc..). * it'd exceed the 80 col limit. * PNG_ macros are only defined if CONFIG_VNC_PNG is defined Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: tight add PNG encodingCorentin Chary6-54/+342
Introduce a new encoding: VNC_ENCODING_TIGHT_PNG [1] (-269) with a new tight filter VNC_TIGHT_PNG (0x0A). When the client tells it supports the Tight PNG encoding, the server will use tight, but will always send encoding pixels using PNG instead of zlib. If the client also told it support JPEG, then the server can send JPEG, because PNG will only be used in the cases zlib was used in normal tight. This encoding was introduced to speed up HTML5 based VNC clients like noVNC [2], but can also be used on devices like iPhone where PNG can be rendered in hardware.

2010-07-22scsi: Dequeue requests before invoking completion callbackJan Kiszka2-1/+12
The request completion callback of the LSI controller may start the next request that can use the same tag as the completed one. As the latter is still enqueued at that point, scsi_send_command will complain about the tag reuse and cancel the completed request. That will cause a double free later on when the completion path cleans up as well. Fix this by dequeuing the request before invoking the callback.

2010-07-22e1000: Fix wrong microwire EEPROM state initializationIzumi Tsutsui1-9/+8
This change fixes initialization of e1000's microwire EEPROM internal state values so that qemu's e1000 emulation works on NetBSD, which doesn't use Intel's em driver but has its own wm driver for the Intel i8254x Gigabit Ethernet. Previously set_eecd() function in e1000.c clears EEPROM internal state values on SK rising edge during CS==L, but according to FM93C06 EEPROM (which is MicroWire compatible) data sheet, EEPROM internal status should be cleared on CS rise edge regardless of SK input: "... a rising edge on this (CS) signal is required to reset the internal state-machine to accept a new cycle .." and nothing should be changed during CS (chip select) is inactive. Intel's em driver seems to explicitly raise SK output after CS is negated in em_standby_eeprom() so many other OSes that use Intel's driver don't have this problem even on the previous e1000.c implementation, but I can't find any articles that say the MICROWIRE or EEPROM spec requires such sequence, and actually hardware works fine without it (i.e. real i82540EM has been working on NetBSD). This fix also changes initialization to clear each state value in struct eecd_state individually rather than using memset() against the whole structre. The old_eecd member stores the last SK and CS signal levels and it should be preserved even after reset of internal EEPROM state to detect next signal edges for proper EEPROM emulation.

2010-07-22Rework debug exception processing for gdb useJan Kiszka2-12/+16
Guest debugging is currently broken under CONFIG_IOTHREAD. The reason is inconsistent or even lacking signaling the debug events from the source VCPU to the main loop and the gdbstub. This patch addresses the issue by pushing this signaling into a CPUDebugExcpHandler: cpu_debug_handler is registered as first handler, thus will be executed last after potential breakpoint emulation handlers. It sets informs the gdbstub about the debug event source, requests a debug exit of the main loop and stops the current VCPU. This mechanism works both for TCG and KVM, with and without IO-thread.
