The Hammerhead platform is built around a AVR32 32-bit microcontroller from Atmel. It offers versatile peripherals, such as ethernet, usb device, usb host etc. The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered Device (PD). Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing. This patch does include the basic support for the fpga device driver, but not the device driver itself.

(I did not compile or test it, please let me know, or help fixing it, if something is wrong with the conversion) This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read. The state will remain "FREEZING" until one of these things happens: 1) Userspace cancels the freezing operation by writing "RUNNING" to the freezer.state file 2) Userspace retries the freezing operation by writing "FROZEN" to the freezer.state file (writing "FREEZING" is not legal and returns EIO) 3) The tasks that blocked the cgroup from entering the "FROZEN" state disappear from the cgroup's set of tasks.

This patch series introduces a cgroup subsystem that utilizes the swsusp freezer to freeze a group of tasks. It's immediately useful for batch job management scripts. It should also be useful in the future for implementing container checkpoint/restart. The freezer subsystem in the container filesystem defines a cgroup file named freezer.state. Reading freezer.state will return the current state of the cgroup. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This patch: The first step in making the refrigerator() available to all architectures, even for those without power management. The purpose of such a change is to be able to use the refrigerator() in a new control group subsystem which will implement a control group freezer.

This patch lets the user enable support for EVKLCD100 and EVKLCD101 (refered to by EVKLCD10X). By enabling EVKLCD10X support the LCD controller and AC97 controller platform devices are added. The user can also choose between the EVKLCD100 (QVGA display) and the EVKLCD101 (VGA display), this is added to automagically select the correct panel timing and resolution parameters. Enabling support for EVKLCD10X addon board will cripple the MCI platform device a bit since they share two GPIO lines (detect and write-protect). These two lines are disabled when EVKLCD10X is enabled. The default configurations are based upon ATNGW100, but with added AC97C and LCDC driver. Virtual terminal is also enabled by default for EVKLCD10X boards. Verified on hardware with a NGW100 + EVKLCD100/101.

This adds support for DMA transfers through the generic DMA engine framework with the DMA slave extensions. The driver has been tested using mmc-block and ext3fs on several SD, SDHC and MMC+ cards. Reads and writes work fine, with read transfer rates up to 7.5 MiB/s on fast cards with debugging disabled. Unfortunately, the driver has been known to lock up from time to time with DMA enabled, so DMA support is currently optional and marked EXPERIMENTAL. However, I didn't see any problems while testing 13 different cards (MMC, SD and SDHC of different brands and sizes), so I suspect the "Initialize BLKR before sending data transfer command" fix that was posted earlier fixed this as well.

The Atmel MCI controller can drive multiple cards through separate sets of pins, but only one at a time. This patch adds support for multiplexing access to the controller so that multiple card slots can be used as if they were hooked up to separate mmc controllers. The atmel-mci driver registers each slot as a separate mmc_host. Both access the same common controller state, but they also have some state on their own for card detection/write protect handling, and separate shadows of the MR and SDCR registers. When one of the slots receives a request from the mmc core, the common controller state is checked. If it's idle, the request is submitted immediately. If not, the request is added to a queue. When a request is done, the queue is checked and if there is a queued request, it is submitted before the completion callback is called. This patch also includes a few cleanups and fixes, including a locking overhaul. I had to change the locking extensively in any case, so I might as well try to get it right. The driver no longer takes any irq-safe locks, which may or may not improve the overall system performance. This patch also adds a bit of documentation of the internal data structures.

Add the necessary platform infrastructure to support multiple mmc/sdcard slots all at once through a single controller. Currently, the driver will use the first valid slot it finds and stick with that, but later patches will add support for switching between several slots on the fly. Extend the platform data structure with per-slot information: MMC/SDcard bus width and card detect/write protect pins. This will affect the pin muxing as well as the capabilities announced to the mmc core. Note that board code is now required to supply a mci_platform_data struct to at32_add_device_mci().
