2008-10-31Make DMA bottom-half driven (v2)aliguori
The current DMA routines are driven by a call in main_loop_wait() after every select. This patch converts the DMA code to be driven by a constantly rescheduled bottom half. The advantage of using a scheduled bottom half is that we can stop scheduling the bottom half when there no DMA channels are runnable. This means we can potentially detect this case and sleep longer in the main loop. The only two architectures implementing DMA_run() are cris and i386. For cris, I converted it to a simple repeating bottom half. I've only compile tested this as cris does not seem to work on a 64-bit host. It should be functionally identical to the previous implementation so I expect it to work. For x86, I've made sure to only fire the DMA bottom half if there is a DMA channel that is runnable. The effect of this is that unless you're using sb16 or a floppy disk, the DMA bottom half never fires. You probably should test this malc. My own benchmarks actually show slight improvement by it's possible the change in timing could affect your demos. Since v1, I've changed the code to use a BH instead of a timer. cris at least seems to depend on faster than 10ms polling.

2008-10-17scsi-generic: correct error managementaurel32
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 QEMUFilealiguori
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).balrog
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)aliguori
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 protocolaliguori
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
