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...

2008-10-13Fix some issues with QEMUFilealiguori1-2/+3
This patch allows QEMUFile's read and write operations to return negative error codes. This is necessary to detect things like closed streams during live migration. It also removes unused code for QEMUFileFD write path. Finally, it makes sure to avoid attempting to flush an output buffer if the file is only being used for input. This was spotted by Uri Lublin.

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.

2008-10-09Fix IDE DIAGNOSE for packet devices (Vincent Sanders)aliguori1-2/+9
The DIAGNOSE command in the qemu IDE implementation has an error when use dfor packet devices. The status register value is dependant on the drive being a packet device or not, this patch corrects the returned status. From the ATA/PI specification (V6 draft): "If the device implements the PACKET command feature set, the device SHALL clear bits 6,5,4,3,2 and 0 in the Status register to zero." A selection of physical devices have been checked and do conform to the specifications behaviour.

2008-10-06Introduce v3 of savevm protocolaliguori1-0/+9
The current savevm/loadvm protocol has some draw backs. It does not support the ability to do progressive saving which means it cannot be used for live checkpointing or migration. The sections sizes are 32-bit integers which means that it will not function when using more than 4GB of memory for a guest. It attempts to seek within the output file which means it cannot be streamed. The current protocol also is pretty lax about how it supports forward compatibility. If a saved section version is greater than what the restore code support, the restore code generally treats the saved data as being in whatever version it supports. This means that restoring a saved VM on an older version of QEMU will likely result in silent guest failure. This patch introduces a new version of the savevm protocol. It has the following features: * Support for progressive save of sections (for live checkpoint/migration) * An asynchronous API for doing save * Support for interleaving multiple progressive save sections (for future support of memory hot-add/storage migration) * Fully streaming format * Strong section version checking Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5434 c046a42c-6fe2-441c-8c8c-71466251a162

2008-09-22LSI SCSI: raise UDC on infinite loop (Marcelo Tosatti)aliguori1-2/+8
Raise UDC (Unexpected Disconnect) when a large enough number of instructions has been executed by the SCRIPTS processor. This "solution" is much simpler than temporarily interrupting execution. This remedies the situation with Windows which downloads SCRIPTS code that busy loops on guest main memory. Their drivers _do_ handle UDC appropriately (at least XP and 2003). It would be nicer to actually detect infinite loops, but until then, this bandaid seems acceptable. Since the situation seems to be rare enough, raise the number of instructions to 10000 (previously 1000). Three people other than myself had success with this patch.
