New Features

This section should contain new features added in this release. Sample format:
|
|
|
|
|
|
|
|
|
|
* **Add a title in the past tense with a full stop.**
|
|
|
|
|
|
|
|
|
|
Add a short 1-2 sentence description in the past tense. The description
|
|
|
|
|
should be enough to allow someone scanning the release notes to understand
|
|
|
|
|
the new feature.
|
|
|
|
|
|
|
|
|
|
If the feature adds a lot of sub-features you can use a bullet list like this.
|
|
|
|
|
|
|
|
|
|
* Added feature foo to do something.
|
|
|
|
|
* Enhanced feature bar to do something else.
|
|
|
|
|
|
|
|
|
|
Refer to the previous release notes for examples.

virtio: support specification 1.0
Modern (v1.0) virtio pci device defines several pci capabilities.
Each cap has a configure structure corresponding to it, and the
cap.bar and cap.offset fields tell us where to find it.
Firstly, we map the pci resources by rte_eal_pci_map_device().
We then could easily locate a cfg structure by:
cfg_addr = dev->mem_resources[cap.bar].addr + cap.offset;
Therefore, the entrance of enabling modern (v1.0) pci device support
is to iterate the pci capability lists, and to locate some configs
we care; and they are:
- common cfg
For generic virtio and virtqueue configuration, such as setting/getting
features, enabling a specific queue, and so on.
- nofity cfg
Combining with `queue_notify_off' from common cfg, we could use it to
notify a specific virt queue.
- device cfg
Where virtio_net_config structure is located.
- isr cfg
Where to read isr (interrupt status).
If any of above cap is not found, we fallback to the legacy virtio
handling.
If succeed, hw->vtpci_ops is assigned to modern_ops, where all
operations are implemented by reading/writing a (or few) specific
configuration space from above 4 cfg structures. And that's basically
how this patch works.
Besides those changes, virtio 1.0 introduces a new status field:
FEATURES_OK, which is set after features negotiation is done.
Last, set the VIRTIO_F_VERSION_1 feature flag.
