Subject: [PATCH v3 02/10] update linux headers
Date: Sat, 19 Mar 2022 15:20:04 +0800 [thread overview]
Message-ID: <20220319072012.525-3-longpeng2@huawei.com> (raw)

Update linux headers to 5.xxx (kernel part is not merged yet)
To support generic vdpa deivce, we need add the following ioctls:
- VHOST_VDPA_GET_CONFIG_SIZE: get the configuration size.
- VHOST_VDPA_GET_VQS_COUNT: get the count of supported virtqueues.
