Hello All, When going through the Ogg format, I have a basic question. As per the RFC the Ogg format encapsulates the logical stream. Now consider the scenario where a raw mono stream is being encoded with Opus Codec. The stream is 48KHz and the length of the stream being encoded is worth 20ms of data. This makes it 960 half words (considering 16 bit format). Now if the final output is say 100

No, the header_type field is a property of a page, not a packet. In it, the continuation flag is used when a single packet spans multiple pages. This is required when a packet is larger than the maximum size of a page (about 64 kB), but in most uses of Opus will almost never be needed. > The Page Segment shall...

The header_type byte is a set of bit flags. 00 means none of them are set, in which case the "unset: ..." language of each flag from RFC 3533 applies. These pages are not continued pages. > The first packet in this ogg file makes sense. > > The second packet (I am taking a part of it) You me...

.../ unmap specific memory ranges, bump lib version to 0.7.0. Convert pci_device_write_u* funtions to take a value instead of a pointer. Fix bad parameter to pci_device_cfg_write in pci_device_cfg_write_u8. Populate device and vendor ID fields at device list creation. Make sure header_type is available in read_bridge_info. Don't pci_device_probe until absolutely necessary. Whitespace police. Initial support for reading expansion ROM via VGA BIOS address. Bump version to 0.9.0. Add linux_devmem.h to file list.

Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very
