2014-02-05pcihp: make pci_read() mmio calback compatible with legacy ACPI hotplugIgor Mammedov
due to recent change introduced by: "pcihp: reduce number of device check events" 'up' field is cleared right after it's read. This is incompatible with legacy BIOS ACPI code where PCNF ACPI method reads this field 32 times. To make pci_read mmio callback compatible with legacy 'up' behavior, pcihp code will need to know in which mode it runs add 'legacy_piix' field to AcpiPciHpState structure and alter register behavior accordingly.

2014-02-05pcihp: reduce number of device check eventsMichael S. Tsirkin
PIIX created a made-up value for the UP register since it was read by guest 32 times for each interrupt. There's no reason to do this for the new PCIHP: register is only read once for each interrupt, so clean up code by making read act as an interrupt acknowledgement: the new UP register clear on read. In this way we cut down the number of bus rescans by a factor of 32, and drop a bunch of code that's now unused. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2014-01-27Fix lan9118 buffer length handlingRoy Franz
The 9118 ethernet controller supports transmission of multi-buffer packets with arbitrary byte alignment of the start and end bytes. All writes to the packet fifo are 32 bits, so the controller discards bytes at the beginning and end of each buffer based on the 'Data start offset' and 'Buffer size' of the TX command 'A' format. This patch uses the provided buffer length to limit the bytes transmitted. Previously all the bytes of the last 32-bit word written to the TX fifo were added to the internal transmit buffer structure resulting in more bytes being transmitted than were submitted to the hardware in the command. This resulted in extra bytes being inserted into the middle of multi-buffer packets when the non-final buffers had non-32bit aligned ending addresses.

2014-01-27Fix lan9118 TX "CMD A" handlingRoy Franz
The 9118 ethernet controller supports transmission of multi-buffer packets with arbitrary byte alignment of the start and end bytes. All writes to the packet fifo are 32 bits, so the controller discards bytes at the beginning and end of each buffer based on the 'Data start offset' and 'Buffer size' of the TX command 'A' format. This patch changes the buffer size and offset internal state variables to be updated on every "TX command A" write. Previously they were only updated for the first segment, which resulted incorrect behavior for packets with more than one segment. Each segment of the packet has its own CMD A command, with its own buffer size and start offset. Also update extraction of fields from the CMD A word to use extract32().

2014-01-24block: rename buffer_alignment to guest_block_sizePaolo Bonzini
The alignment field is now set to the value that is promised to the guest, rather than required by the host. The next patches will make QEMU aware of the host-provided values, so make this clear. The alignment is also not about memory buffers, but about the sectors on the disk, change the documentation of the field. At this point, the field is set by the device emulation, but completely ignored by the block layer.
