Introduction 1.1. Project/Component Working Name: Extensions for LDC transport API 1.2. Name of Document Author/Supplier: Author: Sriharsha Basavapatna 1.3 Date of This Document: 03 August, 2010 4. Technical Description 4.1 Project Summary This case provides a new LDC transport API for LDC clients such as VIO drivers, that need to know whether direct mapped shared memory can be used for data buffers. The LDC transport API was approved under PSARC/2006/152. This case provides an extension of the APIs defined in the original LDC transport API specification. 4.2 Problem and Requirements Currently, the LDC transport API does not provide an interface to obtain the amount of available direct mapping space for the client. Also, there is no restriction on the amount of direct mapping space per LDC. This poses problems for clients that may need to know whether sufficient space is available for direct mapping data buffers exported by a peer LDC end point. For example, the vnet and the vswitch LDC clients need to determine this information prior to negotiating their mode of data transfer. They need to know whether sufficient space is available to direct map the data buffer area and to operate in RxDringData mode (Reference [2]). To achieve the above objectives, the following interface is required: Given a LDC handle, provide the amount of direct mapping space available to the client on that LDC. 4.3 Changes From the Previous Case This project is an extension to the approved case, PSARC/2006/152 - "Logical Domain Channels Transport API". The existing APIs are not changed. But a new API is added, which extends the capabilities of the existing interfaces. The change includes: - A new API function (ldc_info()) to return the amount of direct map space available on a given LDC handle to the client. 4.4 Project Description Please see the new section "Channel Information" on page 12, in the documents provided in the case directory. 4.5 Interfaces 4.5.1 Exported Interfaces Interface Name | Classification | Comment ----------------------|------------------------|---------------------- Data Types: | | ----------- | | ldc_info_t | Consolidation Private | Channel Information | | Functions: | | ----------- | | ldc_info | Consolidation Private | Get Channel Info 4.5.2 Imported Interfaces None 5.
