2011-09-22hw/9pfs: Add fs driver specific details to fscontextAneesh Kumar K.V9-52/+105
Add a new context flag PATHNAME_FSCONTEXT and indicate whether the fs driver track fid using path names. Also add a private pointer that help us to track fs driver specific values in there Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-22hw/9pfs: Add init callback to fs driverAneesh Kumar K.V3-2/+14
This call back can be used to do fs driver specific initialization. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-22hw/9pfs: Move fid pathname tracking to seperate data type.Aneesh Kumar K.V9-299/+548
This enables us to add handles to track fids later. The V9fsPath added is similar to V9fsString except that the size include the NULL byte also. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-22hw/9pfs: Use read-write lock for protecting fid path.Aneesh Kumar K.V8-87/+155
On rename we take the write lock and this ensure path doesn't change as we operate on them. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-22hw/9pfs: Make v9fs_string* functions non-staticAneesh Kumar K.V2-5/+10
We will use them later in other files Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

2011-09-21block/curl: Don't finish AIOCBs too earlyNick Thomas1-19/+49
The previous behaviour was to finish AIOCBs inside curl_aio_readv() if the data was cached. This caused the following failed assertion at hw/ide/pci.c:314: bmdma_cmd_writeb "Assertion `bm->bus->dma->aiocb == ((void *)0)' failed." By scheduling a QEMUBH and performing the completion inside the callback, we avoid this problem. Signed-off-by: Nick Thomas <nick@bytemark.co.uk> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-09-21ahci: add port I/O index-data pairDaniel Verkamp4-3/+76
Implement an I/O space index-data register pair as defined by the AHCI spec, including the corresponding SATA PCI capability and BAR. This allows real-mode code to access the AHCI registers; real-mode code cannot address the memory-mapped register space because it is beyond the first megabyte.

2011-09-21trace: Update docs to use example events that existLluís Vilanova1-7/+9
The events 'qemu_malloc' and 'qemu_free' used in the examples no longer exist, so use 'qemu_vmalloc' and 'qemu_vfree' instead. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-09-21trace: use binary file open mode in simpletraceStefan Hajnoczi1-1/+1
For Windows portability the simple trace backend must use the 'b' file open mode. This prevents the stdio library from mangling 0x0a/0x0d newline characters. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-09-21trace: portable simple trace backend using glibStefan Hajnoczi1-26/+48
Convert the simple trace backend to glib so that it works under Windows. We cannot use pthread directly but glib provides portable abstractions. Also use glib atomics instead of newish gcc builtins which may not be supported on Windows toolchains. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>

2011-09-21trace: allow trace events with string argumentsStefan Hajnoczi1-5/+3
String arguments are useful for producing human-readable traces without post-processing (e.g. stderr backend). Although the simple backend cannot handles strings all others can. Strings should be allowed and the simple backend can be extended to support them. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>

2011-09-21configure: Make missing pkg-config an error rather than a warningPeter Maydell1-2/+2
If pkg-config doesn't exist then make configure fail immediately with a useful error message. Now that glib is a required dependency, proceeding despite the missing pkg-config will just cause us to fail later with a misleading message about glib not being present.

2011-09-21soc_dma: drop soc_dma_port_add_mem_ram()Avi Kivity3-12/+8
It's a trivial wrapper for soc_dma_port_add_mem(), which makes the memory API conversion more difficult because it takes a ram addr_t. Drop. Acked-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Avi Kivity <avi@redhat.com>

2011-09-20block: avoid SIGUSR2Frediano Ziglio2-29/+9
Now that iothread is always compiled sending a signal seems only an additional step. This patch also avoid writing to two pipe (one from signal and one in qemu_service_io). Work with kvm enabled or disabled. strace output is more readable (less syscalls).

2011-09-20scsi: fix sign extension problemsPaolo Bonzini1-15/+7
When assigning a 32-bit value to cmd->xfer (which is 64-bits) it can be erroneously sign extended because the intermediate 32-bit computation is signed.

2011-09-20rbd: ignore failures when reading from default conf locationSage Weil1-10/+4
