2011-10-28block: reinitialize across bdrv_close()/bdrv_open()Stefan Hajnoczi
Several BlockDriverState fields are not being reinitialized across bdrv_close()/bdrv_open(). Make sure they are reset to their default values. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-10-28block: set bs->read_only before .bdrv_open()Stefan Hajnoczi
Several block drivers set bs->read_only in .bdrv_open() but block.c:bdrv_open_common() clobbers its value. Additionally, QED uses bdrv_is_read_only() in .bdrv_open() to decide whether to perform consistency checks. The correct ordering is to initialize bs->read_only from the open flags before calling .bdrv_open(). This way block drivers can override it if necessary and can use bdrv_is_read_only() in .bdrv_open().

2011-10-28qemu-io: delete bs instead of leaking itStefan Hajnoczi
Using bdrv_close() is not enough to free a BlockDriverState. Since we explicitly create it with bdrv_new(), use bdrv_delete() to close and delete it. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-10-28Teach block/vdi about "discarded" (no longer allocated) blocksEric Sunshine
An entry in the VDI block map will hold an offset to the actual block if the block is allocated, or one of two specially-interpreted values if not allocated. Using VirtualBox terminology, value VDI_IMAGE_BLOCK_FREE (0xffffffff) represents a never-allocated block (semantically arbitrary content). VDI_IMAGE_BLOCK_ZERO (0xfffffffe) represents a "discarded" block (semantically zero-filled). block/vdi knows only about VDI_IMAGE_BLOCK_FREE. Teach it about VDI_IMAGE_BLOCK_ZERO.

2011-10-28iSCSI block driverRonnie Sahlberg
This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-10-26target-sparc: Implement ALIGNADDR* inline.Richard Henderson
While ALIGNADDR was implemented out-of-line, ALIGNADDRL was not implemeneted at all. However, this is a very simple operation so we're better off doing this inline. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-10-26target-sparc: Do exceptions management fully inside the helpers.Richard Henderson
This reduces the size of the individual translation blocks, since we only emit a single call for each FOP rather than three. In addition, clear_float_exceptions expands inline to a single byte store. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-10-26target-sparc: Change fpr representation to doubles.Richard Henderson
This allows a more efficient representation for 64-bit hosts. It should be about the same for 32-bit hosts, as we can still access the individual pieces of the double. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-10-26target-sparc: Add accessors for double-precision fpr access.Richard Henderson
Begin using i64 quantities to manipulate double-precision values. On a 64-bit host this will, for the moment, generate less efficient code; on a 32-bit host code quality should be largely unchanged. Code quality for 64-bit will be adjusted with a subsequent patch. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-10-26target-sparc: Add accessors for single-precision fpr access.Richard Henderson
Load, store, and "create destination". This version attempts to change the behaviour of the translator as little as possible. We previously used cpu_tmp32 as the temporary destination, and we continue to use that. This will eventually allow a change in representation of the fprs. Change the name of the cpu_fpr array to make certain that all instances are converted. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-10-25target-sparc: Fix order of function parametersStefan Weil
The MinGW-w64 gcc complains about wrong parameters for gen_helper_fpadd16_s and three other functions. gen_helper_fpadd16_s is declared like this (hidden in lots of macros): static inline void gen_helper_fpadd16s(TCGv_i32 retval, TCGv_ptr arg1, TCGv_i32 arg2, TCGv_i32 arg3); So it looks like cpu_env should be the 2nd parameter. Please review this patch as I have no environment to test it (maybe the 1st parameter should be cpu_dst?).
