2008-10-17scsi-generic: correct error managementaurel321-29/+103
this patch allows to fully use a tape device connected to qemu through the scsi-generic interface. Previous patch introduced tape SCSI commands management, this one improve error case management: - the SCSI controller command completion must be called with the status value, not the sense value. In the case of scsi-generic, the SCSI status is given by the field status of sg_io_hdr_t (the value is left shifted by one regarding status codes defined in /usr/include/scsi/scsi.h) - when a read is aborted due to a mark/EOF/EOD/EOM, the len reported to controller can be 0. LSI controller emulation doesn't know how to manage this. A workaround found is to call the completion routine with SCSI_REASON_DONE just after calling it with SCSI_REASON_DATA with len=0. This patch also manages correctly the block size of the tape device. This patch has been tested with a real tape device "HP C5683A", linux guest (debian etch) and tools like "mt", "tar" and "btape". Windows guest is not better supported than before...

2008-10-17i386/SVM: return amount of ASIDsaurel321-3/+3
With SVM the TLB supports tagging to distinguish TLB entries from different virtual CPUs. This tag is called an ASID. The amount of ASIDs is given in EBX of the SVM-CPUID-leaf. Currently we return 0, which might break hypervisors. Let's better return something >0 here, say 0x10. Since we're flushing the complete TLB on every VM entry and exit we're not making use of the ASID information anyways.

2008-10-14target-i386: Add Core Duo Definitionaurel322-2/+24
This patch adds a CPU definition for the Core Duo CPU. I tried to resemble the original as closely as possible and document what features are missing still. This patch enables the use of a recent CPU definition on 32 bit platforms. It also fixes two issues that went along the line: - invalid xlevel in core2duo spec While looking though the CPUIDs again, I found that xlevel is actually 8. - non-PSE36 support The CoreDuo CPUID does not expose the PSE36 capability, but CPUID 0x80000008 is tied to 36 bits. This broke Windows XP installation for me, so I just set it to 32 bits width when PSE36 is not available. The original CPU also exposes 32 bit width in CPUID 0x80000008.

2008-10-14Expand cache= option and use write-through caching by defaultaliguori7-38/+59
This patch changes the cache= option to accept none, writeback, or writethough to control the host page cache behavior. By default, writethrough caching is now used which internally is implemented by using O_DSYNC to open the disk images. When using -snapshot, writeback is used by default since data integrity it not at all an issue. cache=none has the same behavior as cache=off previously. The later syntax is still supported by now deprecated. I also cleaned up the O_DIRECT implementation to avoid many of the #ifdefs.

2008-10-13Introduce a buffered file wrapper for QEMUFilealiguori3-1/+281
This patch introduces a buffered QEMUFile wrapper. This allows QEMUFile's to be rate limited. It also makes it easier to implement a QEMUFile that is asynchronous since the current QEMUFile API requires that all reads and writes be synchronous. The only real non-obvious part of the API is the "frozen" concept. If the backend returns EAGAIN, the QEMUFile is said to be "frozen". This means no additional output will be sent to the backend until the file is unfrozen. qemu_file_put_notify can be used to unfreeze a frozen file. A synchronous interface is also provided to wait for an unfreeze event. This is used during the final part of live migration when the VM is no longer running.

2008-10-11Increase write buffer size in pflash emulation (Thomas Petazzoni).balrog1-3/+3
The current flash emulation code advertises a write buffer size of 16 bytes (1 << 4, according to offset 0x2A of the CFI table). This is very small compared to normal write buffer sizes, and makes the process of writing to the flash very slow (at least from U-Boot). This patch increases this size to 2048 bytes. Except the modification of the CFI table, the only other required modification is to use "value" instead of "cmd" to set pfl->counter, because cmd is truncated to the 8 lower bits of value, while the number of bytes for a write can now be greater than 255 bytes.

2008-10-08Fix IO performance regression in sparcaliguori9-233/+55
Replace signalfd with signal handler/pipe. There is no way to interrupt the CPU execution loop when a file descriptor becomes readable. This results in a large performance regression in sparc emulation during bootup. This patch switches us to signal handler/pipe which was originally suggested by Ian Jackson. The signal handler lets us interrupt the CPU emulation loop while the write to a pipe lets us avoid the select/signal race condition.
