2015-10-29mmc: dw_mmc: fix the wrong setting for UHS-DDR50 modeJaehoon Chung

2015-10-29nvme: LightNVM supportMatias Bjørling
The first generation of Open-Channel SSDs is based on NVMe. The NVMe driver is extended with support for the LightNVM command set. Detection is made through PCI IDs. Current supported devices are the qemu nvme simulator and CNEX Labs Westlake SSD. The qemu nvme enables support through vendor specific bits in the namespace identification and the CNEX Labs Westlake SSD implements a LightNVM compatible firmware and is detected using the same method as qemu. After detection, vendor specific codes are used to identify the device and enumerate supported features.

2015-10-29lightnvm: Support for Open-Channel SSDsMatias Bjørling
Open-channel SSDs are devices that share responsibilities with the host in order to implement and maintain features that typical SSDs keep strictly in firmware. These include (i) the Flash Translation Layer (FTL), (ii) bad block management, and (iii) hardware units such as the flash controller, the interface controller, and large amounts of flash chips. In this way, Open-channels SSDs exposes direct access to their physical flash storage, while keeping a subset of the internal features of SSDs. LightNVM is a specification that gives support to Open-channel SSDs LightNVM allows the host to manage data placement, garbage collection, and parallelism. Device specific responsibilities such as bad block management, FTL extensions to support atomic IOs, or metadata persistence are still handled by the device. The implementation of LightNVM consists of two parts: core and (multiple) targets. The core implements functionality shared across targets. This is initialization, teardown and statistics. The targets implement the interface that exposes physical flash to user-space applications. Examples of such targets include key-value store, object-store, as well as traditional block devices, which can be application-specific.

2015-10-29megaraid_sas: JBOD sequence number supportsumit.saxena@avagotech.com
Implemented JBOD map which will provide quick access for JBOD path and also provide sequence number. This will help hardware to fail command to the FW in case of any sequence mismatch. Fast Path I/O for JBOD will refer JBOD map (which has sequence number per JBOD device) instead of RAID map. Previously, the driver used RAID map to get device handle for fast path I/O and this not have sequence number information. Now, driver will use JBOD map instead. As part of error handling, if JBOD map is failed/not supported by firmware, driver will continue using legacy behavior. Now there will be three IO paths for JBOD (syspd): - JBOD map with sequence number (Fast Path) - RAID map without sequence number (Fast Path) - FW path via h/w exception queue deliberately setup devhandle 0xFFFF (FW path). Relevant data structures: - Driver send new DCMD MR_DCMD_SYSTEM_PD_MAP_GET_INFO for this purpose. - struct MR_PD_CFG_SEQ- This structure represent map of single physical device. - struct MR_PD_CFG_SEQ_NUM_SYNC- This structure represent whole JBOD map in general(size, count of sysPDs configured, struct MR_PD_CFG_SEQ of syspD with 0 index). - JBOD sequence map size is: sizeof(struct MR_PD_CFG_SEQ_NUM_SYNC) + (sizeof(struct MR_PD_CFG_SEQ) * (MAX_PHYSICAL_DEVICES - 1)) which is allocated while setting up JBOD map at driver load time.
