| | | | | | | | | | | | | | | | The initialize_mountpoint/uninitialise_mountpoint functions are really about setting or clearing the layout driver to be used on this filesystem.

| * NFSv4.1: pnfs: add LAYOUTGET and GETDEVICEINFO infrastructureAndy Adamson2010-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to actually send LAYOUTGET and GETDEVICEINFO. This also adds in the machinery to handle layout state and the deviceid cache. Note that GETDEVICEINFO is not called directly by the generic layer. Instead it is called by the drivers while parsing the LAYOUTGET opaque data in response to an unknown device id embedded therein. RFC 5661 only encodes device ids within the driver-specific opaque data.

| * NFS: client needs to maintain list of inodes with active layoutsAndy Adamson2010-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In particular, server reboot will invalidate all layouts. Note that in order to have an active layout, we must get a successful response from the server. To avoid adding that machinery, this patch just includes a stub that fakes up a successful return. Since the layout is never referenced for io, this is not a problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This information will be used to determine which layout driver, if any, to use for subsequent IO on this filesystem. Each driver is assigned an integer id, with 0 reserved to indicate no driver. The server can in theory return multiple ids.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The APB DMA block handles DMA transfers to and from some peripherals in the Tegra SOC. It reads from sequential addresses on the memory bus, and writes repeatedly to the same address on the APB bus. Two transfer modes are supported, oneshot for transferring a known size to or from a peripheral, and continuous for streaming data. In continuous mode, a callback occurs when the buffer is half full to allow the existing data to be handled and a new request queued.x v2 changes: dma API no longer uses PTR_ERR Signed-off-by: Erik Gilling <konkers@android.com> Signed-off-by: Colin Cross <ccross@android.com>

Setting a pingroup to TEGRA_MUX_SAFE will automatically select a mux setting that is guaranteed not to conflict with any of the hardware blocks. Signed-off-by: Gary King <gking@nvidia.com>

| * | | | microblaze: Support C optimized lib functions for little-endianMichal Simek2010-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimized C library functions can rapidly speedup the kernel. memset doesn't need to be optimized because there is no difference in behavior on little/big endian cpu. Signed-off-by: Michal Simek <monstr@monstr.eu>

| * | | | microblaze: Support timer on AXI liteMichal Simek2010-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New microblaze systems uses two buses. One for memories and flashes and the second for low-speed peripherals which can run on different CLK. This is the reason why the kernel is trying to read clock-frequency directly from node. If there is then the kernel will work with it. If not then cpu CLK is used. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | | | microblaze: Add support for little-endian MicroblazeMichal Simek2010-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Microblaze little-endian toolchain exports __MICROBLAZEEL__ which is used in the kernel to identify little/big endian. The most of the changes are in loading values from DTB which is always big endian. Little endian platforms are based on new AXI bus which has impact to early uartlite initialization.
