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.

2008-10-08Fix 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.

Introduce a max_cpus per-machine variable, allowing individual boards to limit it's number of CPUs.

This adds support for running the sparse checker during the build process. Left it off by default for now, build becomes very noisy with sparse checking turned on as it has to complain alot (partly even in the system headers!). The qemu code base needs quite some cleanups before we should consider turning it on by default.

2008-10-06Switch the memory savevm handler to be "live"aliguori1-141/+152
This patch replaces the static memory savevm/loadvm handler with a "live" one. This handler is used even if performing a non-live migration. The key difference between this handler and the previous is that each page is prefixed with the address of the page. The QEMUFile rate limiting code, in combination with the live migration dirty tracking bits, is used to determine which pages should be sent and how many should be sent. The live save code "converges" when the number of dirty pages reaches a fixed amount. Currently, this is 10 pages. This is something that should eventually be derived from whatever the bandwidth limitation is.

2008-10-06Introduce v3 of savevm protocolaliguori3-45/+248
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

2008-10-06Add bdrv_flush_all()aliguori2-0/+12
This patch adds a bdrv_flush_all() function. It's necessary to ensure that all IO operations have been flushed to disk before completely a live migration. N.B. we don't actually use this now. We really should flush the block drivers using an live savevm callback to avoid unnecessary guest down time.

2008-10-06Allow the monitor to be suspended during non-blocking opaliguori2-1/+20
Live migration happens in the background, but it is useful to make the monitor command appear as if it's blocking. This allows a management tool to immediately know when the live migration has completed without having to poll the migration status. This patch allows the monitor to be suspended from a monitor callback which will prevent new monitor commands from being executed.
