Toshi explains: "No, the default values need to be set to the fallback types, i.e. minimal supported mode. For WC and WT, UC is the fallback type. When PAT is disabled, pat_init() does update the tables below to enable WT per the default BIOS setup. However, when PAT is enabled, but CPU has PAT -errata, WT falls back to UC per the default values." Revert: ca1fec58 'x86/mm/pat: Adjust default caching mode translation tables' Requested-by:

A new BLK namespace "seed" device is created whenever the current seed is successfully probed. However, if that namespace is assigned to a BTT it may never directly experience a successful probe as it is a subordinate device to a BTT configuration. The effect of the current code is that no new namespaces can be instantiated, after the seed namespace, to consume available BLK DPA capacity. Fix this by treating a successful BTT probe event as a successful probe event for the backing namespace. Reported-by:

This patch adds the core module of the MOST driver to the kernel's driver staging area. This module is part of the MOST driver and handles the configuration interface in sysfs, the buffer management and the data routing. MOST defines the protocol, hardware and software layers necessary to allow for the efficient and low-cost transport of control, real-time and packet data using a single medium (physical layer). Media currently in use are fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST also supports various speed grades up to 150 Mbps. For more information on MOST, visit the MOST Cooperation website: www.mostcooperation.com. Cars continue to evolve into sophisticated consumer electronics platforms, increasing the demand for reliable and simple solutions to support audio, video and data communications. MOST can be used to connect multiple consumer devices via optical or electrical physical layers directly to one another or in a network configuration. As a synchronous network, MOST provides excellent Quality of Service and seamless connectivity for audio/video streaming. Therefore, the driver perfectly fits to the mission of Automotive Grade Linux to create open source software solutions for automotive applications. The driver consists basically of three layers. The hardware layer, the core layer and the application layer. The core layer consists of the core module only. This module handles the communication flow through all three layers, the configuration of the driver, the configuration interface representation in sysfs, and the buffer management. For each of the other two layers a selection of modules is provided. These modules can arbitrarily be combined to meet the needs of the desired system architecture. A module of the hardware layer is referred to as an HDM (hardware dependent module). Each module of this layer handles exactly one of the peripheral interfaces of a network interface controller (e.g. USB, MediaLB, I2C). A module of the application layer is referred to as an AIM (application interfacing module). The modules of this layer give access to MOST via one the following ways: character devices, ALSA, Networking or V4L2. To physically access MOST, an Intelligent Network Interface Controller (INIC) is needed. For more information on available controllers visit: www.microchip.com Signed-off-by:

After IO partition recovery, it was possible to get into a situation where a visornic device would repeatedly report: NETDEV WATCHDOG: eth0 (): transmit queue 0 timed out The actual problem would affect any visornic device that was rapidly transmitting at the same time the IO partition was being recovered. Once you hit the problem, the only way to resume use of the nic would be to reboot the Linux client partition. The problem was caused by chstat.sent_xmit and chstat.got_xmit_done NOT getting cleared during IO partition recovery. This is necessary because outstanding xmits would essentially be "abandoned" during such recovery. These fields are now cleared in virtnic_serverdown_complete().

Logic to check for failures of visorchannel_signalinsert() and visorchannel_signalremove() were added, and a new sent_post_failed counter tracks the number of times we failed to post a rcv buffer to the IO partition. Signed-off-by:
