Subject: [PATCH v2 0/3] vdpa: add two ioctl commands to support generic vDPA
Date: Tue, 15 Mar 2022 11:25:50 +0800 [thread overview]
Message-ID: <20220315032553.455-1-longpeng2@huawei.com> (raw)
From: Longpeng <longpeng2@huawei.com>
To support generic vdpa deivce[1], we need add the following ioctls:
- GET_CONFIG_SIZE: the size of the virtio config space (Patch 1)
- GET_VQS_COUNT: the count of virtqueues that exposed (Patch 2)
Changes v2 -> v3:
Patch 2:
- use a separate patch for the u32 converting. [Jason]
Changes v1(RFC) -> v2:
Patch 1:
- be more verbose in commit message and the comment for get_config_size
[Jason]
Patch 2:
- change the type of nvqs to u32 [Jason]
Patch 3:
- drop from this series because Gautam sent another proposal[2]
