2010-05-20tcg-i386: Eliminate extra move from qemu_ld64.Richard Henderson
If the address register overlaps one of the output registers simply issue the clobbering load last, rather than emitting an extra move of the address register. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-05-20tcg-i386: Tidy move operations.Richard Henderson

2010-05-19target-sparc: Simplify ICC generation.Richard Henderson
Use int32 types instead of target_ulong when computing ICC. This simplifies the generated code for 32-bit host and 64-bit guest. Use the same simplified expressions for ICC as were already used for XCC in carry flag generation. Simplify the ADD carry generation to not consider a possible carry-in. Use the more complex carry computation for ADDX only. Use the same carry algorithm for the XCC result of ADDX. Similarly for SUB/SUBX. Use the ADD carry generation functions for TADD/TADDTV. Similarly for SUB and TSUB/TSUBTV. Tidy the code with respect to CODING_STYLE. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-05-19Fix cross compilationStefan Weil
This patch enhances the algorithm which finds the correct settings for SDL. For cross compilations (when cross_prefix is set), it looks for sdl-config with cross prefix. Here is the complete search order: $(cross_prefix}pkg-config (old, only used for cross compilation) ${cross_prefix}sdl_config (new, only used for cross compilation) pkg-config (old, needs PATH) sdl-config (old, needs PATH) Cross SDL packages (or the user) now can simply set a link (for example /usr/bin/i586-mingw32msvc-sdl-config -> /usr/i586-mingw32msvc/bin/sdl-config) which allows cross compilations without PATH modifications. Without the patch, configure and make (which calls configure) typically need a non-standard PATH. Failing to set this special PATH results in broken builds.

2010-05-18target-s390: enable SIGP Initial ResetAlexander Graf
For SMP to work with KVM, we need to properly emulate the SIGP Initial Reset Command. Recent (2.6.32) kernels issue that before the SIGP Reset command that actually wakes up the vcpu. This patch makes -smp work on S390x. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-05-18target-s390: add firmware codeAlexander Graf
This patch adds a firmware blob to the S390 target. The blob is a simple implementation of a virtio client that tries to read the second stage bootloader from sectors described as of offset 0x20 in the MBR. In combination with an updated zipl this allows for booting from virtio block devices. This firmware is built from the same sources as the second stage bootloader. You can find a virtio capable s390-tools in this repo: git://repo.or.cz/s390-tools.git Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-05-18PPC/KVM: make iothread workAlexander Graf
When running with --enable-io-thread the timer we have doesn't help, because it doesn't wake up the CPU thread. So instead we need to actually kick it. While at it I refined the logic a bit to not dumbly trigger a timer every 500ms, but rather do it more often after an interrupt got injected. If there's no level based interrupt to be expected, we don't need the timer anyways. This makes qemu-system-ppc with --enable-io-thread work when using KVM.

2010-05-18qemu-sockets: avoid strlen of NULL pointerJens Osterkamp
If the user wants to create a chardev of type socket but forgets to give a host= option, qemu_opt_get returns NULL. This NULL pointer is then fed into strlen a few lines below without a check which results in a segfault. This fixes it.

2010-05-18linux-user: rlimit conversion between host and target.takasi-y@ops.dti.ne.jp
rlim_t conversion between host and target added. Otherwise there are some incorrect case like - RLIM_INFINITY on 32bit target -> 64bit host. - RLIM_INFINITY on 64bit host -> mips and sparc target ? - Big value(for 32bit target) on 64bit host -> 32bit target. One is added into getrlimit, setrlimit, and ugetrlimit. It converts both RLIM_INFINITY and value bigger than target can hold(>31bit) to RLIM_INFINITY. Another one is added to guest_stack_size calculation introduced by 703e0e89. The rule is mostly same except the result on the case is keeping the value of guest_stack_size. Slightly tested for SH4, and x86_64 -linux-user on x86_64-pc-linux host.

2010-05-17block: Remove special case for vvfatKevin Wolf
The special case doesn't really us buy anything. Without it vvfat works more consistently as a protocol. We get raw on top of vvfat now, which works just as well as using vvfat directly. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2010-05-17block/vdi: Fix image opening and creation for odd disk sizesStefan Weil
The fix is based on a patch from Kevin Wolf. Here his comment: "The number of blocks needs to be rounded up to cover all of the virtual hard disk. Without this fix, we can't even open our own images if their size is not a multiple of the block size." While Kevin's patch addressed vdi_create, my modification also fixes vdi_open which now accepts images with odd disk sizes. v3: Don't allow reading of disk images with too large disk sizes. Neither VBoxManage nor old versions of qemu-img read such images. This change requires rounding of odd disk sizes before we do the checks.

2010-05-17dmg: use qemu block APIChristoph Hellwig
Use bdrv_pwrite to access the backing device instead of pread, and convert the driver to implementing the bdrv_open method which gives it an already opened BlockDriverState for the underlying device. Dmg actually does an lseek to a negative offset in the open routine, which we replace with offset arithmetics after doing a bdrv_getlength.

2010-05-17dmg: use preadChristoph Hellwig
Use pread instead of lseek + read in preparation of using the qemu block API. Note that dmg actually uses the implicit file offset a lot in dmg_open, and we had to replace it with an offset variable. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-17dmg: fix reading of uncompressed chunksChristoph Hellwig
When dmg_read_chunk encounters an uncompressed chunk it currently calls read without any previous adjustment of the file postion. This seems very wrong, and the "reference" implementation in dmg2img does a search to the same offset as done in the various compression cases, so do the same here.

2010-05-17block/vpc: Fix conversion from size to disk geometryStefan Weil
The VHD algorithm calculates a disk geometry which is usually smaller than the requested size. QEMU tried to round up but failed for certain sizes: qemu-img create -f vpc disk.vpc 9437184 would create an image with 9435136 bytes (which is too small for qemu-img convert). Instead of hacking the geometry algorithm, the patch increases the number of sectors until we get enough sectors.

2010-05-17block/vdi: Allow disk images of size 0Stefan Weil
Even it is not very useful, users may create images of size 0. Without the special option CONFIG_ZERO_MALLOC, qemu_mallocz aborts execution when it is told to allocate 0 bytes, so avoid this kind of call.

2010-05-17ide: Fix ide_dma_cancelKevin Wolf
When cancelling a request, bdrv_aio_cancel may decide that it waits for completion of a request rather than for cancellation.
