Re: [libvirt] doc: write separate module for hostdev passthrough and in-use tracking

Hi, List, As the mail I've sent a week before: https://www.redhat.com/archives/libvir-list/2013-March/msg00730.html I'm willing to push this work forward so that the passthrough APIs could be reused by qemu driver and libxl driver (which doesn't support pci passthrough yet and tries to add this function recently), or other drivers. But since this work affacts a lot, I'm not sure if I can control it in a correct way. I write a draft to describe what I'm considering how to do, as in the following and in attachment. Hope to get your review, comment and guidence to improve the work before start coding. Any feedback will be very appreciated! Thanks! Chunyan ------------------------ DRAFT: Write separate module for hostdev passthrough 1. Purposes: * Move hostdev passthrough APIs from qemu_hostdev.ch to separate module so that they could be reused by other hypervisors too * Maintain global in-use state of hostdevs 2. Module design (draft): * New module name: hostdev_driver * New module files: hostdev_driver.ch hostdev_conf.ch * New Definitions: ## [src/driver.h] typedef struct _virHostdevDriver virHostdevDriver; typedef virHostdevDriver *virHostdevDriverPtr; struct _virHosedevDriver { const char *name; virDrvOpen open; virDrvClose close; virDrvPrepareHostdevs prepareHostdevs; virDrvPreparePciHostdevs preparePciHostdevs; virDrvprepareUsbHostdevs prepareUsbHostdevs; virDrvReattachHostdevs reattachHostdevs; virDrvReattachPciHostdevs reattachPciHostdevs; virDrvReattachUsbHostdevs reattachUsbHostdevs; virDrvGetActivePciHostdevList getActivePciHostdevList; virDrvGetActiveUsbHostdevList getActiveUsbHostdevList; virDrvGetDomainActivePciHostdevList getDomainActivePciHostdevList; virDrvGetDomainActiveUsbHostdevList getDomainActiveUsbHostdevList; };
