2012-04-05Use DMADirection type for dma_bdrv_ioDavid Gibson
Currently dma_bdrv_io() takes a 'to_dev' boolean parameter to determine the direction of DMA it is emulating. We already have a DMADirection enum designed specifically to encode DMA directions. This patch uses it for dma_bdrv_io() as well. This involves removing the DMADirection definition from the #ifdef it was inside, but since that only existed to protect the definition of dma_addr_t from places where config.h is not included, there wasn't any reason for it to be there in the first place.

2012-04-05qdev: add blocksize property typeStefan Hajnoczi
Storage interfaces like virtio-blk can be configured with block size information so that the guest can take advantage of efficient I/O request sizes. According to the SCSI Block Commands (SBC) standard a device's block size is "almost always greater than one byte and may be a multiple of 512 bytes". QEMU currently has a 512 byte minimum block size because the block layer functions work at that granularity. Furthermore, the block size should be a power of 2 because QEMU calculates bitmasks from the value. Introduce a "blocksize" property type so devices can enforce these constraints on block size values. If the constraints are relaxed in the future then this property can be updated. Introduce the new PropertyValueNotPowerOf2 QError so QMP clients know exactly why a block size value was rejected.

2012-04-05ide: Adds wwn=hex qdev optionFloris Bos
Allow the user to specify a disk's World Wide Name. Linux guests can address disks by their unique World Wide Name number (e.g. /dev/disk/by-id/wwn-0x5001517959123522).

2012-04-05ide: Add "model=s" qdev optionFloris Bos
Allow the user to override the default disk model name "QEMU HARDDISK". Some Linux distributions use the /dev/disk/by-id/scsi-SATA_name-of-disk- model_serial addressing scheme when refering to partitions in /etc/fstab and elsewhere. This causes problems when starting a disk image taken from an existing physical server under qemu, because when running under qemu name-of-disk-model is always "QEMU HARDDISK". This patch introduces a model=s option which in combination with the existing serial=s option can be used to fake the disk the operating system was previously on, allowing the OS to boot properly.

2012-04-02qdev: give all devices a canonical pathPaolo Bonzini
A strong limitation of QOM right now is that unconverted ports (e.g. all...) do not give a canonical path to devices that are part of the board.

2012-04-02qdev: add children before qdev_initPaolo Bonzini
We want the composition tree to to be in order by the time we call qdev_init, so that a single set of the toplevel realize property can propagate all the way down the composition tree. This is not the case so far. Unfortunately, this is incompatible with calling qdev_init in the constructor wrappers for devices, so for now we need to unattach some devices that are created through those wrappers. This will be fixed by removing qdev_init and instead setting the toplevel realize property after machine init.

2012-04-02serial: clear LSR.TEMT when populating the TSRAnthony Liguori
We never actually clear the TEMT (transmit sending register empty) flag when populating the TSR. We set the flag, but since it's never cleared, setting it is sort of pointless.. I found this with a unit test case. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-04-02serial: fix retry logicAnthony Liguori
I'm not sure if the retry logic has ever worked when not using FIFO mode. I found this while writing a test case although code inspection confirms it is definitely broken. The TSR retry logic will never actually happen because it is guarded by an 'if (s->tsr_rety > 0)' but this is the only place that can ever make the variable greater than zero. That effectively makes the retry logic an 'if (0)'. I believe this is a typo and the intention was >= 0. Once this is fixed though, I see double transmits with my test case. This is because in the non FIFO case, serial_xmit may get invoked while LSR.THRE is still high because the character was processed but the retransmit timer was still active. We can handle this by simply checking for LSR.THRE and returning early. It's possible that the FIFO paths also need some attention.

2012-03-30pl031: switch clock base to rtc_clockPaolo Bonzini
This lets the user specify the desired semantics. By default, the RTC will follow adjustments from the host's NTP client, and will remain in sync when the virtual machine is stopped. The previous behavior, which provides determinism with both icount and qtest, remains available with "-rtc clock=vm". pl031 supports migration, so we need to convert the time base from rtc_clock to vm_clock and back for backwards compatibility. (The rtc_clock may not be synchronized on the two machines, especially with savevm/loadvm, so the conversion is needed anyway. And since any time base will do, why not pick the one base that is backwards compatible). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2012-03-19scsi: copy serial number into VPD page 0x83Paolo Bonzini
Currently QEMU passes the qdev device id to the guest in an ASCII-string designator in page 0x83. While this is fine, it does not match what real hardware does; usually the ASCII-string designator there hosts another copy of the serial number (there can be other designators, for example with a world-wide name). Do the same for QEMU SCSI disks. ATAPI does not support VPD pages, so it does not matter there. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-03-19scsi-cd: check ready condition before processing several commandsPaolo Bonzini
This commit is more or less obvious. What it caused is less obvious: SCSI CD drives failed to eject under Linux, though for example the "change" command worked okay. This happens because of the autoclose option in the Linux CD-ROM driver. The actual chain of events is quite complex and somehow involves udev helpers; the actual command that matters is READ TOC, though honestly it's not really clear to me how because it should always be invoked after autoclose, not before.
