2009-06-16allow CPUID vendor overrideAndre Przywara
KVM-enabled QEMU will always report the vendor ID of the physical CPU it is running on. Allow to override this if explicitly requested on the command line. It will not suffice to name a CPU type (like -cpu phenom), but you have to explicitly set the vendor: -cpu phenom,vendor=AuthenticAMD Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-06-16vnc: improve numpad support for qemu console.Gerd Hoffmann

2009-06-16Remove io_index argument from cpu_register_io_memory()Avi Kivity
The parameter is always zero except when registering the three internal io regions (ROM, unassigned, notdirty). Remove the parameter to reduce the API's power, thus facilitating future change. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-06-16l2_allocate: Write complete sectorsKevin Wolf
When modifying the L1 table, l2_allocate() needs to write complete sectors instead of single entries. The L1 table is already in memory, reading it from disk in the block layer to align the request is wasted performance.

2009-06-16qcow2: Rename global functionsKevin Wolf
The qcow2 source is now split into several more manageable files. During the conversion quite some functions that were static before needed to be changed to be global to make the source compile again. We were lucky enough not to get name conflicts with these additional global names, but they are not nice. This patch adds a qcow2_ prefix to all of the global functions in qcow2.

2009-06-16qcow2: Split out guest cluster functionsKevin Wolf
qcow2-cluster.c contains all functions related to the management of guest clusters, i.e. what the guest sees on its virtual disk. This code is about mapping these guest clusters to host clusters in the image file using the two-level lookup tables.

2009-06-16qcow2: Split out refcount handlingKevin Wolf
qcow2-refcount.c contains all functions which are related to cluster allocation and management in the image file. A large part of this is the reference counting of these clusters. Also a header file qcow2.h is introduced which will contain the interface of the split qcow2 modules. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-16qcow2: Change default cluster size to 64kKevin Wolf
Larger cluster sizes mean less metadata. This has been discussion a few times, let's do it now. This turns 64k clusters on by default for new images. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-16vnc: rework VncState release workflow.Gerd Hoffmann
Split socket closing and releasing of VncState into two steps. First close the socket and set the variable to -1 to indicate shutdown in progress. Do the actual release in a few places where we can be sure it doesn't cause trouble in form of use-after-free. Add some checks for a valid socket handle to make sure we don't try to use the closed socket. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-16raw-posix: Remove O_RDWR when attempting to open a file read-onlyAvi Kivity
When we open a file, we first attempt to open it read-write, then fall back to read-only. Unfortunately we reuse the flags from the previous attempt, so both attempts try to open the file with write permissions, and fail. Fix by clearing the O_RDWR flag from the previous attempt.

2009-06-16raw-posix: open flags use BDRV_ namespace, not posix namespaceAvi Kivity

2009-06-16linux-user: remove duplicate tswap32() from do_getsockopt()Laurent Vivier
This issue has been detected with tests/linux-tests.c: linux-test.c:330: getsockopt 327 len = sizeof(val); 328 chk_error(getsockopt(server_fd, SOL_SOCKET, SO_TYPE, &val, &len)); 329 if (val != SOCK_STREAM) 330 error("getsockopt"); In linux-user/syscall.c:do_getsockopt(), we have: ... val = tswap32(val); ... if (put_user_u32(val, optval_addr)) ... whereas "put_user_u32" calls in the end "__put_user" which uses "tswap32". So the "val = tswap32(val);" is useless and wrong. This patch removes it. Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>

2009-06-16RFC: fix fcntl support in linux-user - new tryArnaud Patard (Rtp)
Hi, This is a new try to fix the fcntl support in linux-user. I tried to adress all comments but as the previous version is several weeks old, it's possible that I've missed some. This patch doesn't handle linux specific fcntl flags. My plan is to get this version of the patch reviewed/fixed and then, add them if wanted.

2009-06-16Return EOPNOTSUPP instead of ENOSYS for *xattr* syscallsArnaud Patard
In current code, we're sending ENOSYS to target when a syscall for the xattrs is done. This makes applications like ls complain loudly about that and breaks scripts parsing the output. Moreover, iirc, implemented features of filesystems are are sending EOPNOTSUPP (I've not checked so I may be a little bit wrong on that...). So, I'm proposing to return -EOPNOTSUPP and make ls happy Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
2009-06-16Fix struct termios host - target translationArnaud Patard
When converting the termios structure between host and target in target_to_host_termios and host_to_target_termios, the c_cc[] array is never initialised. Calling memset() before using it allows to run successfully "stty echo / stty -echo" on arm-linux-user target (host being x86 and mips).

2009-06-16linux-user: fix utimensatRiku Voipio
The glibc function for utimensat glibc returns -EINVAL when the path is null which is a different behaviour with the syscall. path can be null because internally the glibc is using utimensat with path null when implmenting futimens. If path is null, call futimes instead. don't try to copy timespec from user if is NULL. Add configure check for older systems Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
