The variable len can get a negative return value from cvtnum, which we check for, but which is impossible with the current unsigned variable type. Currently the if(len < 0) check is pointless.

Currently virtio-serial supports a maximum of 31 ports. Specifying the 'max_ports' parameter to be > 31 on the cmd line causes badness.

Commit 68a1c816 broke qemu on hosts not using guest base. It uses reserved_va unconditionally in mmap.c. To avoid to many #ifdef #endif blocks, define RESERVED_VA as either reserved_va or 0ul, and use it instead of reserved_va, similarly to what has been done with guest_base/GUEST_BASE.

Moving toward a single copy of the elf binary loading code. Fill in the details of the loaded image into a struct image_info.

At the bottom of the a.out support was the unimplemented load_aout_interp function. There were other portions of the support that didn't look right; when I went to look in the Linux kernel for clarification, I found that the support for such interpreters has been removed from binfmt_elf. There doesn't seem to be any reason to keep this broken support in qemu. Signed-off-by: NRichard Henderson <rth@twiddle.net> Signed-off-by: NEdgar E. Iglesias <edgar.iglesias@gmail.com>

First, adjust load_symbols to accept a load_bias parameter. At the same time, read the entire section header table in one go, use pread instead f lseek+read for the symbol and string tables, and properly free allocated structures on error exit paths. Second, adjust load_elf_interp to compute load_bias. This requires finding out the built-in load addresses. Which allows us to honor a pre-linked interpreter image when possible, and eliminate the hard-coded INTERP_MAP_SIZE value. Signed-off-by: NRichard Henderson <rth@twiddle.net> Signed-off-by: NEdgar E.

I caught padzero not properly initializing the .bss segment on a statically linked Alpha program. Rather than a minimal patch, replace the gross code with a single mmap+memset. Share more code between load_elf_interp and load_elf_binary. Legally, an ELF program need not have just a single .bss; and PT_LOAD segment can have memsz > filesz.

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.

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.

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: NCorentin Chary <corentincj@iksaif.net> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

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.
