2008-12-07LSI53C895A: Handle empty SCRIPTS opcode (Justin Chevrier)balrog
Basically after each DMA transfer the Openserver driver would issue an empty (0) SCRIPTS opcode. As the opcode is essentially a NOP it has no second DWORD and therefore the DSP should only be incremented by 4 bytes instead of the 8 bytes we currently do. Here's a snippet of the log: lsi_scsi: Data ready tag=0x100d9 len=16384 ... lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a09000 lsi_scsi: DMA addr=0x07a09000 len=1024 lsi_scsi: SCRIPTS dsp=068c5e58 opcode 00000000 arg 01000400 lsi_scsi: Wrong phase got 1 expected 0 Note the 2nd DWORD after the empty opcode; the next opcode in the DMA transfer sequence. As can be expected the address after that has the next DMA address to use. After the attached patch the DMA transfer is able to complete successfully: lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a0d000 lsi_scsi: DMA addr=0x07a0d000 len=1024 lsi_scsi: SCRIPTS dsp=068c5e5c opcode 01000400 arg 07a0d400 lsi_scsi: DMA addr=0x07a0d400 len=1024 ... Tested againsted Openserver 5.0.5 and Debian ARM.

2008-12-04do boundary check based on absolute value (Glauber Costa)aliguori
For backward operations, dstpitch and srcpitch can be negative. This leads BLTUNSAFE macro into an overflow, and as a result, it avoids performing operations that are perfectly valid. The visible effect that led to that patch was the gnome-panel bar in Fedora10. Before this patch, you could see garbage clobbering a big portion of the bar. After this patch, this garbage is gone.

2008-12-04Use writeback caching by default with qcow2aliguori
qcow2 writes a cluster reference count on every cluster update. This causes performance to crater when using anything but cache=writeback. This is most noticeable when using savevm. Right now, qcow2 isn't a reliable format regardless of the type of cache your using because metadata is not updated in the correct order. Considering this, I think it's somewhat reasonable to use writeback caching by default with qcow2 files. It at least avoids the massive performance regression for users until we sort out the issues in qcow2.

2008-12-04Add virtio-balloon supportaliguori
This adds a VirtIO based balloon driver. It uses madvise() to actually balloon the memory when possible. Until 2.6.27, KVM forced memory pinning so we must disable ballooning unless the kernel actually supports it when using KVM. It's always safe when using TCG.

2008-12-04Remove TARGET_PAGE_SIZE from virtio interface (Hollis Blanchard)aliguori
TARGET_PAGE_SIZE should only be used internal to qemu, not in guest/host interfaces. The virtio frontend code in Linux uses two constants (PFN shift and vring alignment) for the interface, so update qemu to match. I've tested this with PowerPC KVM and confirmed that it fixes virtio problems when using non-TARGET_PAGE_SIZE pages in the guest.

2008-12-02Change order of metadata update to prevent loosing guest data because of ↵aliguori
unexpected exit (Gleb Natapov) Currently the order is this (during cow since it's the interesting case): 1. Decrement refcount of old clusters 2. Increment refcount for newly allocated clusters 3. Copy content of old sectors that will not be rewritten 4. Update L2 table with pointers to new clusters 5. Write guest data into new clusters (asynchronously) There are several problems with this order. The first one is that if qemu crashes (or killed or host reboots) after new clusters are linked into L2 table but before user data is written there, then on the next reboot guest will find neither old data nor new one in those sectors and this is not what gust expects even when journaling file system is in use. The other problem is that if qemu is killed between steps 1 and 4 then refcount of old cluster will be incorrect and may cause snapshot corruption. The patch change the order to be like this: 1. Increment refcount for newly allocated clusters 2. Write guest data into new clusters (asynchronously) 3. Copy content of old sectors that were not rewritten 4. Update L2 table with pointers to new clusters 5. Decrement refcount of old clusters Unexpected crash may cause cluster leakage, but guest data should be safe.
