From: Anthony PERARD Date: Tue, 7 May 2019 14:54:08 +0000 (+0100) Subject: libxl: Add device_{config,type} to libxl__ao_device X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=fdaef8e475faac954c8b9b0ba10eb15c6a8b40aa;p=people%2Flarsk%2Fxen.git libxl: Add device_{config,type} to libxl__ao_device These two fields help to give more information about the device been hotplug/hotunplug to callbacks. There is already `dev' of type `libxl__device', but it is mostly useful when the backend/frontend is xenstore. Some device (like `usbdev') don't have devid, so `dev' can't be used.
